6 latexmk - generate LaTeX document

9 latexmk [options] [file ...]
10
12 Latexmk completely automates the process of compiling a LaTeX document.
13 Essentially, it is like a specialized relative of the general make
14 utility, but one which determines dependencies automatically and has
15 some other very useful features. In its basic mode of operation
16 latexmk is given the name of the primary source file for a document,
17 and it issues the appropriate sequence of commands to generate a .dvi,
18 .ps, .pdf and/or hardcopy version of the document.
19
20 By default latexmk will run the commands necessary to generate a .dvi
21 file.
22
23 Latexmk can also be set to run continuously with a suitable previewer.
24 In that case the latex program (or one of its relatives), etc, are
25 rerun whenever one of the source files is modified, and the previewer
26 automatically updates the on-screen view of the compiled document.
27
28 Latexmk determines which are the source files by examining the log
29 file. (Optionally, it also examines the list of input and output files
30 generated by the -recorder option of modern versions of latex (and
31 pdflatex, xelatex, lualatex, etc). See the documentation for the
32 -recorder option of latexmk below.) When latexmk is run, it examines
33 properties of the source files, and if any have been changed since the
34 last document generation, latexmk will run the various LaTeX processing
35 programs as necessary. In particular, it will repeat the run of latex
36 (or a related program)) often enough to resolve all cross references;
37 depending on the macro packages used. With some macro packages and
38 document classes, four, or even more, runs may be needed. If necessary,
39 latexmk will also run bibtex, biber, and/or makeindex. In addition,
40 latexmk can be configured to generate other necessary files. For exam‐
41 ple, from an updated figure file it can automatically generate a file
42 in encapsulated postscript or another suitable format for reading by
43 LaTeX.
44
45 Latexmk has two different previewing options. With the simple -pv
46 option, a dvi, postscript or pdf previewer is automatically run after
47 generating the dvi, postscript or pdf version of the document. The
48 type of file to view is selected according to configuration settings
49 and command line options.
50
51 The second previewing option is the powerful -pvc option (mnemonic:
52 "preview continuously"). In this case, latexmk runs continuously, reg‐
53 ularly monitoring all the source files to see if any have changed.
54 Every time a change is detected, latexmk runs all the programs neces‐
55 sary to generate a new version of the document. A good previewer will
56 then automatically update its display. Thus the user can simply edit a
57 file and, when the changes are written to disk, latexmk completely
58 automates the cycle of updating the .dvi (and/or the .ps and .pdf)
59 file, and refreshing the previewer's display. It's not quite WYSIWYG,
60 but usefully close.
61
62 For other previewers, the user may have to manually make the previewer
63 update its display, which can be (e.g., with some versions of xdvi and
64 gsview) as simple as forcing a redraw of its display.
65
66 Latexmk has the ability to print a banner in gray diagonally across
67 each page when making the postscript file. It can also, if needed,
68 call an external program to do other postprocessing on generated dvi
69 and postscript files. (See the options -dF and -pF, and the documenta‐
70 tion for the $dvi_filter and $ps_filter configuration variables.)
71 These capabilities are leftover from older versions of latexmk, but are
72 currently non-functional. More flexibility can be obtained in current
73 versions, since the command strings for running latex, pdflatex, etc
74 can now be configured to run multiple commands. This also extends the
75 possibility of postprocessing generated files.
76
77 Latexmk is highly configurable, both from the command line and in con‐
78 figuration files, so that it can accommodate a wide variety of user
79 needs and system configurations. Default values are set according to
80 the operating system, so latexmk often works without special configura‐
81 tion on MS-Windows, cygwin, Linux, OS-X, and other UNIX systems. See
82 the section "Configuration/Initialization (rc) Files", and then the
83 later sections "How to Set Variables in Initialization Files", "Format
84 of Command Specifications", "List of Configuration Variables Usable in
85 Initialization Files", "Custom Dependencies", and "Advanced Configura‐
86 tion"
87
88 A very annoying complication handled very reliably by latexmk, is that
89 LaTeX is a multiple pass system. On each run, LaTeX reads in informa‐
90 tion generated on a previous run, for things like cross referencing and
91 indexing. In the simplest cases, a second run of LaTeX suffices, and
92 often the log file contains a message about the need for another pass.
93 However, there is a wide variety of add-on macro packages to LaTeX,
94 with a variety of behaviors. The result is to break simple-minded
95 determinations of how many runs are needed and of which programs.
96 Latexmk has a highly general and efficient solution to these issues.
97 The solution involves retaining between runs information on the source
98 files, and a symptom is that latexmk generates an extra file (with
99 extension .fdb_latexmk, by default) that contains the source file
100 information.
101
102
104 In general the command line to invoke latexmk has the form
105
106 latexmk [options] [file]
107
108 All options can be introduced by single or double "-" characters, e.g.,
109 "latexmk -help" or "latexmk --help".
110
111 Note 1: In addition to the options in the list below, latexmk recog‐
112 nizes almost all the options recognized by the latex, pdflatex programs
113 (and their relatives) in their current TeXLive and MiKTeX implementa‐
114 tions. Some of the options for these programs also trigger special
115 action or behavior by latexmk, in which case they have specific expla‐
116 nations in this document. Otherwise, they are just passed through to a
117 called latex or pdflatex program. Run latexmk with the -showextraop‐
118 tions to get a list of the options that latexmk accepts and that are
119 simply passed through to latex or pdflatex (etc). See also the expla‐
120 nation of the -showextraoptions option for more information.
121
122 Note 2: In this documentation, the program pdflatex is often referred
123 to. Users of programs like lualatex and xelatex should know that from
124 latexmk's point of view, these other programs behave very like pdfla‐
125 tex, i.e., they make a pdf file from a tex file, etc. So whenever
126 pdflatex is mentioned without mention of the other programs, the state‐
127 ments apply equally to lualatex, xelatex, and any other similar pro‐
128 grams. Latexmk can be easily configured to use whichever of these pro‐
129 grams is needed. See the documentation for the following options:
130 -pdflua, -pdfxe, -lualatex, and -xelatex, and also see the documenta‐
131 tion for the $pdflatex, $lualatex, and $xelatex configuration vari‐
132 ables. At present latexmk does not do automatic detection of which
133 program is to be used.
134
135
136 Definitions of options and arguments
137
138
139 file One or more files can be specified. If no files are specified,
140 latexmk will, by default, run on all files in the current work‐
141 ing directory with a ".tex" extension. This behavior can be
142 changed: see the description concerning the @default_files vari‐
143 able in the section "List of configuration variables usable in
144 initialization files".
145
146 If a file is specified without an extension, then the ".tex"
147 extension is automatically added, just as LaTeX does. Thus, if
148 you specify:
149
150 latexmk foo
151
152 then latexmk will operate on the file "foo.tex".
153
154 There are certain restrictions on what characters can be in a
155 filename; certain characters are either prohibited or problem‐
156 atic for the latex etc programs. These characters are: "$",
157 "%", "\", "~", the double quote character, and the control char‐
158 acters null, tab, form feed, carriage return, line feed, and
159 delete. In addition "&" is prohibited when it is the first
160 character of a filename.
161
162 Latexmk gives a fatal error when it detects any of the above
163 characters in the TeX filename(s) specified on the command line.
164 However before testing for illegal characters, latexmk removes
165 matching pairs of double quotes from a filename. This matches
166 the behavior of latex etc, and deals with problems that occa‐
167 sionally result from filenames that have been incorrectly quoted
168 on the command line. In addition, under Microsoft Windows, the
169 forward slash character "\" is a directory separator, so latexmk
170 replaces it by a backward slash "/", which is also a legal
171 directory separator in Windows, and is accepted by latex etc.
172
173
174 -auxdir=FOO or -aux-directory=FOO
175 Sets the directory for auxiliary output files of (pdf)latex
176 (.aux, .log etc). This achieves its effect by the -aux-direc‐
177 tory option of (pdf)latex, which currently is only implemented
178 on the MiKTeX version of (pdf)latex.
179
180 See also the -outdir/-output-directory options, and the
181 $aux_dir, $out_dir, and $search_path_separator configuration
182 variables of latexmk. In particular, see the documentation of
183 $out_dir for some complications on what directory names are
184 suitable.
185
186 If you also use the -cd option, and the specified auxiliary out‐
187 put directory is a relative path, then the path is interpreted
188 relative to the document directory.
189
190
191 -bibtex
192 When the source file uses bbl files for bibliography, run bibtex
193 or biber as needed to regenerate the bbl files.
194
195 This property can also be configured by setting the $bibtex_use
196 variable to 2 in a configuration file.
197
198
199 -bibtex-
200 Never run bibtex or biber. Also, always treat .bbl files as
201 precious, i.e., do not delete them in a cleanup operation.
202
203 A common use for this option is when a document comes from an
204 external source, complete with its bbl file(s), and the user
205 does not have the corresponding bib files available. In this
206 situation use of the -bibtex- option will prevent latexmk from
207 trying to run bibtex or biber, which would result in overwriting
208 of the bbl files.
209
210 This property can also be configured by setting the $bibtex_use
211 variable to 0 in a configuration file.
212
213
214 -bibtex-cond
215 When the source file uses bbl file(s) for the bibliography, run
216 bibtex or biber as needed to regenerate the bbl files, but only
217 if the relevant bib file(s) exist. Thus when the bib files are
218 not available, bibtex or biber is not run, thereby avoiding
219 overwriting of the bbl file(s). Also, always treat .bbl files
220 as precious, i.e., do not delete them in a cleanup operation.
221
222 This is the default setting. It can also be configured by set‐
223 ting the $bibtex_use variable to 1 in a configuration file.
224
225 The reason for using this setting is that sometimes a .bbl file
226 is available containing the bibliography for a document, but the
227 .bib file is not available. An example would be for a scien‐
228 tific journal where authors submit .tex and .bbl files, but not
229 the original .bib file. In that case, running bibtex or biber
230 would not work, and the .bbl file should be treated as a user
231 source file, and not as a file that can be regenerated on
232 demand.
233
234 (Note that it is possible for latexmk to decide that the bib
235 file does not exist, even though the bib file does exist and
236 bibtex or biber finds it. The problem is that the bib file may
237 not be in the current directory but in some search path; the
238 places latexmk and bibtex or biber cause to be searched need not
239 be identical. On modern installations of TeX and related pro‐
240 grams this problem should not arise, since latexmk uses the
241 kpsewhich program to do the search, and kpsewhich should use the
242 same search path as bibtex and biber. If this problem arises,
243 use the -bibtex option when invoking latexmk.)
244
245 Note that this value does not work properly if the document uses
246 biber instead of bibtex. (There's a long story why not.)
247
248
249 -bibtex-cond1
250 The same as -bibtex-cond1 except that .bbl files are only
251 treated as precious if one or more bibfiles fails to exist.
252
253 Thus if all the bib files exist, bibtex or biber is run to gen‐
254 erate .bbl files as needed, and then it is appropriate to delete
255 the bbl files in a cleanup operation since they can be re-gener‐
256 ated.
257
258 This property can also be configured by setting the $bibtex_use
259 variable to 1.5 in a configuration file.
260
261
262 -bm <message>
263 A banner message to print diagonally across each page when con‐
264 verting the dvi file to postscript. The message must be a sin‐
265 gle argument on the command line so be careful with quoting spa‐
266 ces and such.
267
268 Note that if the -bm option is specified, the -ps option is
269 assumed.
270
271
272 -bi <intensity>
273 How dark to print the banner message. A decimal number between
274 0 and 1. 0 is black and 1 is white. The default is 0.95, which
275 is OK unless your toner cartridge is getting low.
276
277
278 -bs <scale>
279 A decimal number that specifies how large the banner message
280 will be printed. Experimentation is necessary to get the right
281 scale for your message, as a rule of thumb the scale should be
282 about equal to 1100 divided by the number of characters in the
283 message. The default is 220.0 which is just right for 5 charac‐
284 ter messages.
285
286
287 -commands
288 List the commands used by latexmk for processing files, and then
289 exit.
290
291
292 -c Clean up (remove) all regeneratable files generated by latex and
293 bibtex or biber except dvi, postscript and pdf. These files are
294 a combination of log files, aux files, latexmk's database file
295 of source file information, and those with extensions specified
296 in the @generated_exts configuration variable. In addition,
297 files specified by the $clean_ext and @generated_exts configura‐
298 tion variables are removed.
299
300 This cleanup is instead of a regular make. See the -gg option
301 if you want to do a cleanup then a make.
302
303 Treatment of .bbl files: If $bibtex_use is set to 0 or 1, bbl
304 files are always treated as non-regeneratable. If $bibtex_use
305 is set to 1.5, bbl files are counted as non-regeneratable condi‐
306 tionally: If the bib file exists, then bbl files are regenerat‐
307 able, and are deleted in a clean up. But if $bibtex_use is 1.5
308 and a bib file doesn't exist, then the bbl files are treated as
309 non-regeneratable and hence are not deleted.
310
311 In contrast, if $bibtex_use is set to 2, bbl files are always
312 treated as regeneratable, and are deleted in a cleanup.
313
314 Treatment of files generated by custom dependencies: If
315 $cleanup_includes_cusdep_generated is nonzero, regeneratable
316 files are considered as including those generated by custom
317 dependencies and are also deleted. Otherwise these files are
318 not deleted.
319
320
321 -C Clean up (remove) all regeneratable files generated by latex and
322 bibtex or biber. This is the same as the -c option with the
323 addition of dvi, postscript and pdf files, and those specified
324 in the $clean_full_ext configuration variable.
325
326 This cleanup is instead of a regular make. See the -gg option
327 if you want to do a cleanup than a make.
328
329 See the -c option for the specification of whether or not .bbl
330 files are treated as non-regeneratable or regeneratable.
331
332 If $cleanup_includes_cusdep_generated is nonzero, regeneratable
333 files are considered as including those generated by custom
334 dependencies and are also deleted. Otherwise these files are
335 not deleted.
336
337
338 -CA (Obsolete). Now equivalent to the -C option. See that option
339 for details.
340
341
342 -cd Change to the directory containing the main source file before
343 processing it. Then all the generated files (.aux, .log, .dvi,
344 .pdf, etc) will be relative to the source file.
345
346 This option is particularly useful when latexmk is invoked from
347 a GUI configured to invoke latexmk with a full pathname for the
348 source file.
349
350 This option works by setting the $do_cd configuration variable
351 to one; you can set that variable if you want to configure
352 latexmk to have the effect of the -cd option without specifying
353 it on the command line. See the documentation for that vari‐
354 able.
355
356
357 -cd- Do NOT change to the directory containing the main source file
358 before processing it. Then all the generated files (.aux, .log,
359 .dvi, .pdf, etc) will be relative to the current directory
360 rather than the source file.
361
362 This is the default behavior and corresponds to the behavior of
363 the latex and pdflatex programs. However, it is not desirable
364 behavior when latexmk is invoked by a GUI configured to invoke
365 latexmk with a full pathname for the source file. See the -cd
366 option.
367
368 This option works by setting the $do_cd configuration variable
369 to zero. See the documentation for that variable for more
370 information.
371
372
373 -CF Remove the file containing the database of source file informa‐
374 tion, before doing the other actions requested.
375
376
377 -d Set draft mode. This prints the banner message "DRAFT" across
378 your page when converting the dvi file to postscript. Size and
379 intensity can be modified with the -bs and -bi options. The -bm
380 option will override this option as this is really just a short
381 way of specifying:
382
383 latexmk -bm DRAFT
384
385 Note that if the -d option is specified, the -ps option is
386 assumed.
387
388
389 -deps Show a list of dependent files after processing. This is in the
390 form of a dependency list of the form used by the make program,
391 and it is therefore suitable for use in a Makefile. It gives an
392 overall view of the files without listing intermediate files, as
393 well as latexmk can determine them.
394
395 By default the list of dependent files is sent to stdout (i.e.,
396 normally to the screen unless you've redirected latexmk's out‐
397 put). But you can set the filename where the list is sent by the
398 -deps-out= option.
399
400 See the section "USING latexmk WITH make" for an example of how
401 to use a dependency list with make.
402
403 Users familiar with GNU automake and gcc will find that the
404 -deps option is very similar in its purpose and results to the
405 -M option to gcc. (In fact, latexmk also has options -M, -MF,
406 and -MP options that behave like those of gcc.)
407
408
409 -dependents
410 Equivalent to -deps.
411
412
413 -deps- Do not show a list of dependent files after processing. (This
414 is the default.)
415
416
417 -dependents-
418 Equivalent to -deps-.
419
420
421 -deps-out=FILENAME
422 Set the filename to which the list of dependent files is writ‐
423 ten. If the FILENAME argument is omitted or set to "-", then
424 the output is sent to stdout.
425
426 Use of this option also turns on the output of the list of
427 dependent files after processing.
428
429
430 -dF Dvi file filtering. The argument to this option is a filter
431 which will generate a filtered dvi file with the extension
432 ".dviF". All extra processing (e.g. conversion to postscript,
433 preview, printing) will then be performed on this filtered dvi
434 file.
435
436 Example usage: To use dviselect to select only the even pages of
437 the dvi file:
438
439 latexmk -dF "dviselect even" foo.tex
440
441
442 -diagnostics
443 Print detailed diagnostics during a run. This may help for
444 debugging problems or to understand latexmk's behavior in diffi‐
445 cult situations.
446
447
448 -dvi Generate dvi version of document.
449
450
451 -dvi- Turn off generation of dvi version of document. (This may get
452 overridden, if some other file is made (e.g., a .ps file) that
453 is generated from the dvi file, or if no generated file at all
454 is requested.)
455
456
457 -e <code>
458 Execute the specified initialization code before processing.
459 The code is Perl code of the same form as is used in latexmk's
460 initialization files. For more details, see the information on
461 the -r option, and the section about "Configuration/initializa‐
462 tion (RC) files". The code is typically a sequence of assign‐
463 ment statements separated by semicolons.
464
465 The code is executed when the -e option is encountered during
466 latexmk's parsing of its command line. See the -r option for a
467 way of executing initialization code from a file. An error
468 results in latexmk stopping. Multiple instances of the -r and
469 -e options can be used, and they are executed in the order they
470 appear on the command line.
471
472 Some care is needed to deal with proper quoting of special char‐
473 acters in the code on the command line. For example, suppose
474 you want to set the latex command to use its -shell-escape
475 option, then under UNIX/Linux you could use the line
476
477 latexmk -e '$latex=q/latex %O -shell-escape %S/' file.tex
478
479 Note that the single quotes block normal UNIX/Linux command
480 shells from treating the characters inside the quotes as spe‐
481 cial. (In this example, the q/.../ construct is a Perl idiom
482 equivalent to using single quotes. This avoids the complica‐
483 tions of getting a quote character inside an already quoted
484 string in a way that is independent of both the shell and the
485 operating-system.)
486
487 The above command line will NOT work under MS-Windows with
488 cmd.exe or command.com or 4nt.exe. For MS-Windows with these
489 command shells you could use
490
491 latexmk -e "$latex=q/latex %O -shell-escape %S/" file.tex
492
493 or
494
495 latexmk -e "$latex='latex %O -shell-escape %S'" file.tex
496
497 The last two examples will NOT work with UNIX/Linux command
498 shells.
499
500 (Note: the above examples show are to show how to use the -e to
501 specify initialization code to be executed. But the particular
502 effect can be achieved also by the use of the -latex option with
503 less problems in dealing with quoting.)
504
505
506 -f Force latexmk to continue document processing despite errors.
507 Normally, when latexmk detects that LaTeX or another program has
508 found an error which will not be resolved by further processing,
509 no further processing is carried out.
510
511 Note: "Further processing" means the running of other programs
512 or the rerunning of latex (etc) that would be done if no errors
513 had occurred. If instead, or additionally, you want the latex
514 (etc) program not to pause for user input after an error, you
515 should arrange this by an option that is passed to the program,
516 e.g., by latexmk's option -interaction=nonstopmode.
517
518
519 -f- Turn off the forced processing-past-errors such as is set by the
520 -f option. This could be used to override a setting in a con‐
521 figuration file.
522
523
524 -g Force latexmk to process document fully, even under situations
525 where latexmk would normally decide that no changes in the
526 source files have occurred since the previous run. This option
527 is useful, for example, if you change some options and wish to
528 reprocess the files.
529
530
531 -g- Turn off -g.
532
533
534 -gg "Super go mode" or "clean make": clean out generated files as if
535 -C had been given, and then do a regular make.
536
537
538 -h, -help
539 Print help information.
540
541
542 -jobname=STRING
543 Set the basename of output files(s) to STRING, instead of the
544 default, which is the basename of the specified TeX file. (At
545 present, STRING should not contain spaces.)
546
547 This is like the same option for current implementations of the
548 latex, pdflatex, etc, and the passing of this option to these
549 programs is part of latexmk's implementation of -jobname.
550
551 There is one enhancement, that the STRING may contain the place‐
552 holder '%A'. This will be substituted by the basename of the TeX
553 file. The primary purpose is when multiple files are specified
554 on the command line to latexmk, and you wish to use a jobname
555 with a different file-dependent value for each file. For exam‐
556 ple, suppose you had .tex files test1.tex and test2.tex, and you
557 wished to compare the results of compilation by pdflatex and
558 those with xelatex. Then under a unix-type operating system you
559 could use the command line
560
561 latexmk -pdf -jobname=%A-pdflatex *.tex
562 latexmk -pdfxe -jobname=%A-xelatex *.tex
563
564 Then the .aux, .log, and .pdf files from the use of pdflatex
565 would have basenames test1-pdflatex and test2-pdflatex, while
566 from xelatex, the basenames would be test1-xelatex and
567 test2-xelatex.
568
569 Under MS-Windows with cmd.exe, you would need to double the per‐
570 cent sign, so that the percent character is passed to latexmk
571 rather than being used to substitute an environment variable:
572
573 latexmk -pdf -jobname=%%A-pdflatex *.tex
574 latexmk -pdfxe -jobname=%%A-xelatex *.tex
575
576
577 -l Run in landscape mode, using the landscape mode for the preview‐
578 ers and the dvi to postscript converters. This option is not
579 normally needed nowadays, since current previewers normally
580 determine this information automatically.
581
582
583 -l- Turn off -l.
584
585
586 -latex This sets the generation of dvi files by latex, and turns off
587 the generation of pdf and ps files.
588
589 Note: to set the command used when latex is specified, see the
590 -latex="COMMAND" option.
591
592
593 -latex="COMMAND"
594 This sets the string specifying the command to run latex, and is
595 typically used to add desired options. Since the string nor‐
596 mally contains spaces, it should be quoted, e.g.,
597
598 latexmk -latex="latex --shell-escape %O %S" foo.tex
599
600 The specification of the contents of the string are the same as
601 for the $latex configuration variable. Depending on your oper‐
602 ating system and the command-line shell you are using, you may
603 need to change the single quotes to double quotes (or something
604 else).
605
606 Note: This option when provided with the COMMAND argument only
607 sets the command for invoking latex; it does not turn on the use
608 of latex. That is done by other options or in an initialization
609 file.
610
611 To set the command for running pdflatex (rather than the command
612 for latex) see the -pdflatex option.
613
614
615 -logfilewarninglist
616 -logfilewarnings After a run of (pdf)latex, give a list of warn‐
617 ings about undefined citations and references (unless silent
618 mode is on).
619
620 See also the $silence_logfile_warnings configuration variable.
621
622
623 -logfilewarninglist-
624 -logfilewarnings- After a run of (pdf)latex, do not give a list
625 of warnings about undefined citations and references. (Default)
626
627 See also the $silence_logfile_warnings configuration variable.
628
629
630 -lualatex
631 Use lualatex. That is, use lualatex to process the source
632 file(s) to pdf. The generation of dvi and postscript files is
633 turned off.
634
635 This option is equivalent to using the following set of options
636
637 -pdflua -dvi- -ps-
638
639 (Note: Note that the method of implementation of this option,
640 but not its intended effect, differ from some earlier versions
641 of latexmk.)
642
643
644 -lualatex="COMMAND"
645 This sets the string specifying the command to run lualatex. It
646 behaves like the -pdflatex option, but sets the variable $luala‐
647 tex.
648
649 Note: This option when provided with the COMMAND argument only
650 sets the command for invoking lualatex; it does not turn on the
651 use of lualatex. That is done by other options or in an initial‐
652 ization file.
653
654
655 -M Show list of dependent files after processing. This is equiva‐
656 lent to the -deps option.
657
658
659 -MF file
660 If a list of dependents is made, the -MF specifies the file to
661 write it to.
662
663
664 -MP If a list of dependents is made, include a phony target for each
665 source file. If you use the dependents list in a Makefile, the
666 dummy rules work around errors the program make gives if you
667 remove header files without updating the Makefile to match.
668
669
670 -MSWinBackSlash
671 This option only has an effect when latexmk is running under MS-
672 Windows. This is that when latexmk runs a command under MS-Win‐
673 dows, the Windows standard directory separator "\" is used to
674 separate directory components in a file name. Internally,
675 latexmk uses "/" for the directory separator character, which is
676 the character used by Unix-like systems.
677
678 This is the default behavior. However the default may have been
679 overridden by a configuration file (latexmkrc file) which sets
680 $MSWin_back_slash=0.
681
682
683 -MSWinBackSlash-
684 This option only has an effect when latexmk is running under MS-
685 Windows. This is that when latexmk runs a command under MS-Win‐
686 dows, the substitution of "\" for the separator character
687 between directory components of a file name is not done. Instead
688 the forward slash "/" is used, the same as on Unix-like systems.
689 This is acceptable in most situations under MS-Windows, provided
690 that filenames are properly quoted, as latexmk does by default.
691
692 See the documentation for the configuration variable
693 $MSWin_back_slash for more details.
694
695
696 -new-viewer
697 When in continuous-preview mode, always start a new viewer to
698 view the generated file. By default, latexmk will, in continu‐
699 ous-preview mode, test for a previously running previewer for
700 the same file and not start a new one if a previous previewer is
701 running. However, its test sometimes fails (notably if there is
702 an already-running previewer that is viewing a file of the same
703 name as the current file, but in a different directory). This
704 option turns off the default behavior.
705
706
707 -new-viewer-
708 The inverse of the -new-viewer option. It puts latexmk in its
709 normal behavior that in preview-continuous mode it checks for an
710 already-running previewer.
711
712
713 -nobibtex
714 Never run bibtex or biber. Equivalent to the -bibtex- option.
715
716
717 -norc Turn off the automatic reading of initialization (rc) files.
718
719 N.B. Normally the initialization files are read and obeyed, and
720 then command line options are obeyed in the order they are
721 encountered. But -norc is an exception to this rule: it is
722 acted on first, no matter where it occurs on the command line.
723
724
725 -outdir=FOO or -output-directory=FOO
726
727 Sets the directory for the output files of (pdf)latex. This
728 achieves its effect by the -output-directory option of
729 (pdf)latex, which currently (Dec. 2011 and later) is implemented
730 on the common versions of (pdf)latex, i.e., MiKTeX and TeXLive.
731 It may not be present in other versions.
732
733 See also the -auxdir/-aux-directory options, and the $aux_dir,
734 $out_dir, and $search_path_separator configuration variables of
735 latexmk. In particular, see the documentation of $out_dir for
736 some complications on what directory names are suitable.
737
738 If you also use the -cd option, and the specified output direc‐
739 tory is a relative path, then the path is interpreted relative
740 to the document directory.
741
742
743 -p Print out the document. By default the file to be printed is
744 the first in the list postscript, pdf, dvi that is being made.
745 But you can use the -print=... option to change the type of file
746 to be printed, and you can configure this in a start up file (by
747 setting the $print_type variable).
748
749 However, printing is enabled by default only under UNIX/Linux
750 systems, where the default is to use the lpr command and only on
751 postscript files. In general, the correct behavior for printing
752 very much depends on your system's software. In particular,
753 under MS-Windows you must have suitable program(s) available,
754 and you must have configured the print commands used by latexmk.
755 This can be non-trivial. See the documentation on the $lpr,
756 $lpr_dvi, and $lpr_pdf configuration variables to see how to set
757 the commands for printing.
758
759 This option is incompatible with the -pv and -pvc options, so it
760 turns them off.
761
762
763 -pdf Generate pdf version of document using pdflatex. (If you wish
764 to use lualatex or xelatex, you can use whichever of the options
765 -pdflua, -pdfxe, -lualatex or -xelatex applies.) To configure
766 latexmk to have such behavior by default, see the section on
767 "Configuration/initialization (rc) files".
768
769
770 -pdfdvi
771 Generate pdf version of document from the dvi file, by default
772 using dvipdf.
773
774
775 -pdflua
776 Generate pdf version of document using lualatex.
777
778
779 -pdfps Generate pdf version of document from the .ps file, by default
780 using ps2pdf.
781
782
783 -pdfxe Generate pdf version of document using xelatex. Note that to
784 optimize processing time, latexmk uses xelatex to generate an
785 .xdv file rather than a pdf file directly. Only after possibly
786 multiple runs to generate a fully up-to-date .xdv file does
787 latexmk then call xdvipdfmx to generate the final .pdf file.
788
789 (Note: The reason why latexmk arranges for xelatex to make an
790 .xdv file instead of the xelatex's default of a .pdf file is as
791 follows: When the document includes large graphics files, espe‐
792 cially .png files, the production of a .pdf file can be quite
793 time consuming, even when the creation of the .xdv file by xela‐
794 tex is fast. So the use of the intermediate .xdv file can
795 result in substantial gains in procesing time, since the .pdf
796 file is produced once rather than on every run of xelatex.)
797
798
799 -pdf- Turn off generation of pdf version of document. (This can be
800 used to override a setting in a configuration file. It may get
801 overridden if some other option requires the generation of a pdf
802 file.)
803
804 If after all options have been processed, pdf generation is
805 still turned off, then generation of a dvi file will be turned
806 on, and then the program used to compiled a document will be
807 latex (or, more precisely, whatever program is configured to be
808 used in the $latex configuration variable).
809
810
811 -pdflatex
812 This sets the generation of pdf files by pdflatex, and turns off
813 the generation of dvi and ps files.
814
815 Note: to set the command used when pdflatex is specified, see
816 the -pdflatex="COMMAND" option.
817
818
819 -pdflatex="COMMAND"
820 This sets the string specifying the command to run pdflatex, and
821 is typically used to add desired options. Since the string nor‐
822 mally contains spaces, it should be quoted, e.g.,
823
824 latexmk -pdf -pdflatex="pdflatex --shell-escape %O %S"
825 foo.tex
826
827 The specification of the contents of the string are the same as
828 for the $pdflatex configuration variable. (The option -pdflatex
829 in fact sets the variable $pdflatex.) Depending on your operat‐
830 ing system and the command-line shell you are using, you may
831 need to change the single quotes to double quotes (or something
832 else).
833
834 Note: This option when provided with the COMMAND argument only
835 sets the command for invoking pdflatex; it does not turn on the
836 use of pdflatex. That is done by other options or in an initial‐
837 ization file.
838
839 To set the command for running latex (rather than the command
840 for pdflatex) see the -latex option.
841
842
843 -pdflualatex="COMMAND"
844 Equivalent to -lualatex="COMMAND".
845
846
847 -pdfxelatex="COMMAND"
848 Equivalent to -xelatex="COMMAND".
849
850
851 -pretex=CODE
852
853 Given that CODE is some TeX code, this options sets that code to
854 be executed before inputting source file. This only works if
855 the command for invoking the relevant *latex is suitably config‐
856 ured. See the documentation of the variable $pre_tex_code, and
857 the substitution strings %P and %U for more details. This
858 option works by setting the variable $pre_tex_code.
859
860 See also the -usepretex option.
861
862 An example:
863
864 latexmk -pretex='\AtBeginDocument{Message\par}' -usepretex
865 foo.tex
866
867 But this is better written
868
869 latexmk -usepretex='\AtBeginDocument{Message\par}' foo.tex
870
871 If you already have a suitable command configured, you only need
872
873 latexmk -pretex='\AtBeginDocument{Message\par}' foo.tex
874
875
876 -print=dvi, -print=ps, -print=pdf, -print=auto,
877 Define which kind of file is printed. This option also ensures
878 that the requisite file is made, and turns on printing.
879
880 The (default) case -print=auto determines the kind of print file
881 automatically from the set of files that is being made. The
882 first in the list postscript, pdf, dvi that is among the files
883 to be made is the one used for print out.
884
885
886 -ps Generate postscript version of document.
887
888
889 -ps- Turn off generation of postscript version of document. This can
890 be used to override a setting in a configuration file. (It may
891 get overridden by some other option that requires a postscript
892 file, for example a request for printing.)
893
894
895 -pF Postscript file filtering. The argument to this option is a
896 filter which will generate a filtered postscript file with the
897 extension ".psF". All extra processing (e.g. preview, printing)
898 will then be performed on this filtered postscript file.
899
900 Example of usage: Use psnup to print two pages on the one page:
901
902 latexmk -ps -pF 'psnup -2' foo.tex
903
904 or
905
906 latexmk -ps -pF "psnup -2" foo.tex
907
908 Whether to use single or double quotes round the "psnup -2" will
909 depend on your command interpreter, as used by the particular
910 version of perl and the operating system on your computer.
911
912
913 -pv Run file previewer. If the -view option is used, this will
914 select the kind of file to be previewed (.dvi, .ps or .pdf).
915 Otherwise the viewer views the "highest" kind of file selected,
916 by the -dvi, -ps, -pdf, -pdfps options, in the order .dvi, .ps,
917 .pdf (low to high). If no file type has been selected, the dvi
918 previewer will be used. This option is incompatible with the -p
919 and -pvc options, so it turns them off.
920
921
922 -pv- Turn off -pv.
923
924
925 -pvc Run a file previewer and continually update the .dvi, .ps,
926 and/or .pdf files whenever changes are made to source files (see
927 the Description above). Which of these files is generated and
928 which is viewed is governed by the other options, and is the
929 same as for the -pv option. The preview-continuous option -pvc
930 can only work with one file. So in this case you will normally
931 only specify one filename on the command line. It is also
932 incompatible with the -p and -pv options, so it turns these
933 options off.
934
935 The -pvc option also turns off force mode (-f), as is normally
936 best for continuous preview mode. If you really want force
937 mode, use the options in the order -pvc -f.
938
939 With a good previewer the display will be automatically updated.
940 (Under some but not all versions of UNIX/Linux "gv -watch" does
941 this for postscript files; this can be set by a configuration
942 variable. This would also work for pdf files except for an
943 apparent bug in gv that causes an error when the newly updated
944 pdf file is read.) Many other previewers will need a manual
945 update.
946
947 Important note: the acroread program on MS-Windows locks the pdf
948 file, and prevents new versions being written, so it is a bad
949 idea to use acroread to view pdf files in preview-continuous
950 mode. It is better to use a different viewer: SumatraPDF and
951 gsview are good possibilities.
952
953 There are some other methods for arranging an update, notably
954 useful for many versions of xdvi and xpdf. These are best set
955 in latexmk's configuration; see below.
956
957 Note that if latexmk dies or is stopped by the user, the
958 "forked" previewer will continue to run. Successive invocations
959 with the -pvc option will not fork new previewers, but latexmk
960 will normally use the existing previewer. (At least this will
961 happen when latexmk is running under an operating system where
962 it knows how to determine whether an existing previewer is run‐
963 ning.)
964
965
966 -pvc- Turn off -pvc.
967
968
969 -pvctimeout
970 Do timeout in pvc mode after period of inactivity, which is 30
971 min. by default. Inactivity means a period when latexmk has
972 detected no file changes and hence has not taken any actions
973 like compiling the document.
974
975
976 -pvctimeout-
977 Don't do timeout in pvc mode after inactivity.
978
979
980 -pvctimeoutmins=<time>
981 Set period of inactivity in minutes for pvc timeout.
982
983
984 -quiet Same as -silent
985
986
987 -r <rcfile>
988 Read the specified initialization file ("RC file") before pro‐
989 cessing.
990
991 Be careful about the ordering: (1) Standard initialization files
992 -- see the section below on "Configuration/initialization (RC)
993 files" -- are read first. (2) Then the options on the command
994 line are acted on in the order they are given. Therefore if an
995 initialization file is specified by the -r option, it is read
996 during this second step. Thus an initialization file specified
997 with the -r option can override both the standard initialization
998 files and previously specified options. But all of these can be
999 overridden by later options.
1000
1001 The contents of the RC file just comprise a piece of code in the
1002 Perl programming language (typically a sequence of assignment
1003 statements); they are executed when the -r option is encountered
1004 during latexmk's parsing of its command line. See the -e option
1005 for a way of giving initialization code directly on latexmk's
1006 command line. An error results in latexmk stopping. Multiple
1007 instances of the -r and -e options can be used, and they are
1008 executed in the order they appear on the command line.
1009
1010
1011 -recorder
1012 Give the -recorder option with latex and pdflatex. In (most)
1013 modern versions of these programs, this results in a file of
1014 extension .fls containing a list of the files that these pro‐
1015 grams have read and written. Latexmk will then use this file to
1016 improve its detection of source files and generated files after
1017 a run of latex or pdflatex. This is the default setting of
1018 latexmk, unless overridden in an initialization file.
1019
1020 For further information, see the documentation for the $recorder
1021 configuration variable.
1022
1023
1024 -recorder-
1025 Do not supply the -recorder option with latex and pdflatex.
1026
1027
1028 -rules Show a list of latemk's rules and dependencies after processing.
1029
1030
1031 -rules-
1032 Do not show a list of latexmk's rules and dependencies after
1033 processing. (This is the default.)
1034
1035
1036 -showextraoptions
1037 Show the list of extra latex and pdflatex options that latexmk
1038 recognizes, but that it simply passes through to the programs
1039 latex, pdflatex, etc when they are run. These options are
1040 (currently) a combination of those allowed by the TeXLive and
1041 MiKTeX implementations. (If a particular option is given to
1042 latexmk but is not handled by the particular implementation of
1043 latex or pdflatex that is being used, that program will probably
1044 give an error message.) These options are very numerous, but
1045 are not listed in this documentation because they have no effect
1046 on latexmk's actions.
1047
1048 There are a few options (-includedirectory=dir, -initialize,
1049 -ini) that are not recognized, either because they don't fit
1050 with latexmk's intended operations, or because they need special
1051 processing by latexmk that isn't implemented (at least, not
1052 yet).
1053
1054 There are also options that are accepted by latex etc, but
1055 instead trigger actions by latexmk: -help, -version.
1056
1057 Finally, there are certain options for latex and pdflatex (e.g.,
1058 -recorder) that trigger special actions or behavior by latexmk
1059 itself as well as being passed in some form to the called latex
1060 and pdflatex program, or that affect other programs as well.
1061 These options do have entries in this documentation. These
1062 options are: -jobname=STRING, -aux-directory=dir, -output-direc‐
1063 tory=DIR, -quiet, and -recorder.
1064
1065
1066 -silent
1067 Run commands silently, i.e., with options that reduce the amount
1068 of diagnostics generated. For example, with the default set‐
1069 tings, the command "latex -interaction=batchmode" is used for
1070 latex, and similarly for its friends.
1071
1072 See also the -logfilewarninglist and -logfilewarninglist-
1073 options.
1074
1075 Also reduce the number of informational messages that latexmk
1076 itself generates.
1077
1078 To change the options used to make the commands run silently,
1079 you need to configure latexmk with changed values of its config‐
1080 uration variables, the relevant ones being $bib‐
1081 tex_silent_switch, $biber_silent_switch, $dvipdf_silent_switch,
1082 $dvips_silent_switch, $latex_silent_switch, $luala‐
1083 tex_silent_switch $makeindex_silent_switch, $pdfla‐
1084 tex_silent_switch, and $xelatex_silent_switch
1085
1086
1087 -stdtexcmds
1088 Sets the commands for latex, etc, so that they are the standard
1089 ones. This is useful to override special configurations.
1090
1091 The result is that $latex = 'latex %O %S', and similarly for
1092 $pdflatex, $lualatex, and $xelatex. (The option -no-pdf needed
1093 for $xelatex is provided automatically, given that %O appears in
1094 the definition.)
1095
1096
1097 -time Show CPU time used. See also the configuration variable
1098 $show_time.
1099
1100
1101 -time- Do not show CPU time used. See also the configuration variable
1102 $show_time.
1103
1104
1105 -use-make
1106 When after a run of latex or pdflatex, there are warnings about
1107 missing files (e.g., as requested by the LaTeX \input, \include,
1108 and \includgraphics commands), latexmk tries to make them by a
1109 custom dependency. If no relevant custom dependency with an
1110 appropriate source file is found, and if the -use-make option is
1111 set, then as a last resort latexmk will try to use the make pro‐
1112 gram to try to make the missing files.
1113
1114 Note that the filename may be specified without an extension,
1115 e.g., by \includegraphics{drawing} in a LaTeX file. In that
1116 case, latexmk will try making drawing.ext with ext set in turn
1117 to the possible extensions that are relevant for latex (or as
1118 appropriate pdflatex).
1119
1120 See also the documentation for the $use_make_for_missing_files
1121 configuration variable.
1122
1123
1124 -use-make-
1125 Do not use the make program to try to make missing files.
1126 (Default.)
1127
1128
1129 -usepretex
1130 Sets the command lines for latex, etc, so that they use the code
1131 that is defined by the variable $pre_tex_code or that is set by
1132 the option -pretex=CODE to execute the specified TeX code before
1133 the source file is read. This option overrides any previous
1134 definition of the command lines.
1135
1136 The result is that $latex = 'latex %O %P', and similarly for
1137 $pdflatex, $lualatex, and $xelatex. (The option -no-pdf needed
1138 for $xelatex is provided automatically, given that %O appears in
1139 the definition.)
1140
1141
1142 -usepretex=CODE
1143 Equivalent to -pretex=CODE -usepretex. Example
1144
1145 latexmk -usepretex='\AtBeginDocument{Message\par}' foo.tex
1146
1147
1148 -v, -version
1149 Print version number of latexmk.
1150
1151
1152 -verbose
1153 Opposite of -silent. This is the default setting.
1154
1155
1156 -view=default, -view=dvi, -view=ps, -view=pdf, -view=none
1157 Set the kind of file used when previewing is requested (e.g., by
1158 the -pv or -pvc switches). The default is to view the "highest"
1159 kind of requested file (in the low-to-high order .dvi, .ps,
1160 .pdf).
1161
1162 Note the possibility -view=none where no viewer is opened at
1163 all. One example of is use is in conjunction with the -pvc
1164 option, when you want latexmk to do a compilation automatically
1165 whenever source file(s) change, but do not want a previewer to
1166 be opened.
1167
1168
1169 -Werror
1170 This causes latexmk to return a non-zero status code if any of
1171 the files processed gives a warning about problems with cita‐
1172 tions or references (i.e., undefined citations or references or
1173 about multiply defined references). This is after latexmk has
1174 completed all the runs it needs to try and resolve references
1175 and citations. Thus -Werror causes latexmk to treat such warn‐
1176 ings as errors, but only when they occur on the last run of
1177 (pdf)latex and only after processing is complete. Also can be
1178 set by the configuration variable $warnings_as_errors.
1179
1180
1181 -xelatex
1182 Use xelatex. That is, use xelatex to process the source file(s)
1183 to pdf. The generation of dvi and postscript files is turned
1184 off.
1185
1186 This option is equivalent to using the following set of options
1187
1188 -pdfxe -dvi- -ps-
1189
1190 [Note: Note that the method of implementation of this option,
1191 but not its intended primary effect, differ from some earlier
1192 versions of latexmk. Latexmk first uses xelatex to make an .xdv
1193 file, and does all the extra runs needed (including those of
1194 bibtex, etc). Only after that does it make the pdf file from
1195 the .xdv file, using xdvipdfmx. See the documentation for the
1196 -pdfxe for why this is done.]
1197
1198
1199 -xelatex="COMMAND"
1200 This sets the string specifying the command to run xelatex. It
1201 sets the variable $xelatex.
1202
1203 Warning: It is important to ensure that the -no-pdf is used when
1204 xelatex is invoked, since latexmk expects xelatex to produce an
1205 .xdv file, not a .pdf file. If you provide %O in the command
1206 specification, this will be done automatically. See the docu‐
1207 mentation for the -pdfxe option for why latexmk makes a .xdv
1208 file rather than a .pdf file when xelatex is used.
1209
1210 An example of the use of the -pdfxelatex option:
1211
1212 latexmk -pdfxe -pdfxelatex="xelatex --shell-escape %O %S"
1213 foo.tex
1214
1215 Note: This option when provided with the COMMAND argument only
1216 sets the command for invoking lualatex; it does not turn on the
1217 use of lualatex. That is done by other options or in an initial‐
1218 ization file.
1219
1220
1221 Compatibility between options
1222
1223 The preview-continuous option -pvc can only work with one file. So in
1224 this case you will normally only specify one filename on the command
1225 line.
1226
1227 Options -p, -pv and -pvc are mutually exclusive. So each of these
1228 options turns the others off.
1229
1230
1232 % latexmk thesis # run latex enough times to resolve
1233 cross-references
1234
1235 % latexmk -pvc -ps thesis# run latex enough times to resolve
1236 cross-references, make a postscript
1237 file, start a previewer. Then
1238 watch for changes in the source
1239 file thesis.tex and any files it
1240 uses. After any changes rerun latex
1241 the appropriate number of times and
1242 remake the postscript file. If latex
1243 encounters an error, latexmk will
1244 keep running, watching for
1245 source file changes.
1246
1247 % latexmk -c # remove .aux, .log, .bbl, .blg, .dvi,
1248 .pdf, .ps & .bbl files
1249
1250
1251
1253 Some possibilities:
1254
1255 a. If you get a strange error, do look carefully at the output that is
1256 on the screen and in log files. While there is much that is notori‐
1257 ously verbose in the output of latex (and that is added to by latexmk),
1258 the verbosity is there for a reason: to enable the user to diagnose
1259 problems. Latexmk does repeat some messages at the end of a run that
1260 it thinks would otherwise be easy to miss in the middle of other out‐
1261 put.
1262
1263 b. Generally, remember that latexmk does its work by running other pro‐
1264 grams. Your first priority in dealing with errors should be to examine
1265 what went wrong with the individual programs. Then you need to correct
1266 the causes of errors in the runs of these programs. (Often these come
1267 from errors in the source document, but they could also be about miss‐
1268 ing LaTeX packages, etc.)
1269
1270 c. If latexmk doesn't run the programs the way you would like, then you
1271 need to look in this documentation at the list of command line options
1272 and then at the sections on configuration/initialization files. A lot
1273 of latexmk's behavior is configurable to deal with particular situa‐
1274 tions. (But there is a lot of reading!)
1275
1276 The remainder of these notes consists of ideas for dealing with more
1277 difficult situations.
1278
1279 d. Further tricks can involve replacing the standard commands that
1280 latexmk runs by other commands or scripts.
1281
1282 e. For possible examples of code for use in an RC file, see the direc‐
1283 tory example_rcfiles in the distribution of latexmk (e.g., at
1284 http://mirror.ctan.org/support/latexmk/example_rcfiles). Even if these
1285 examples don't do what you want, they may provide suitable inspiration.
1286
1287 f. There's a useful trick that can be used when you use lualatex
1288 instead of pdflatex (and in some related situations). The problem is
1289 that latexmk won't notice a dependency on a file, bar.baz say, that is
1290 input by the lua code in your document instead of by the LaTeX part.
1291 (Thus if you change bar.baz and rerun latexmk, then latexmk will think
1292 no files have changed and not rerun lualatex, whereas if you had
1293 '\input{bar.baz}' in the LaTeX part of the document, latexmk would
1294 notice the change.) One solution is just to put the following some‐
1295 where in the LaTeX part of the document:
1296
1297 \typeout{(bar.baz)}
1298
1299 This puts a line in the log file that latexmk will treat as implying
1300 that the file bar.baz was read. (At present I don't know a way of
1301 doing this automatically.) Of course, if the file has a different
1302 name, change bar.baz to the name of your file.

1306 h. Look on tex.stackexchange, i.e., at http://tex.stackex‐

1308 your problem.

1312 j. Or ask me (the author of latexmk). My e-mail is at the end of this
1313 documentation.
1314
1315
1316
1318 When one of the latex engines is run, the usual situation is that latex
1319 produces a .dvi file, while pdflatex and lualatex produce a .pdf file.
1320 For xelatex the default is to produce a .pdf file, but to optimize pro‐
1321 cessing time latexmk runs xelatex its -no-pdf option so that it pro‐
1322 duces an .xdv file. Further processing by latexmk takes this as a
1323 starting point.
1324
1325 However, the actual output file may differ from the normal expectation;
1326 and then latexmk can adjust its processing to accommodate this situa‐
1327 tion. The difference in output file type can happen for two reasons:
1328 One is that for latex, pdflatex and lualatex the document itself can
1329 override the defaults. The other is that there may be a configuration,
1330 or misconfiguration, such that the program that latexmk invokes to com‐
1331 pile the document is not the expected one, or is given options incom‐
1332 patible with what latexmk initially expects. (E.g., the -output-for‐
1333 mat=... option could be used with lualatex, or xelatex gets invoked
1334 without the -no-pdf option.)
1335
1336 Under latex and pdflatex, control of the output format by the document
1337 is done by setting the \pdfoutput macro. Under lualatex, the \output‐
1338 mode macro is used instead.
1339
1340 One example of an important use-case for document control of the output
1341 format is a document that uses the psfrag package to insert graphical
1342 elements in the output file. The psfrag package achieves its effects by
1343 inserting postscript code in the output of the compilation of the docu‐
1344 ment. This entails the use of compilation to a .dvi file, followed by
1345 the use of conversion to a postscript file (either directly, as by
1346 dvips or implicitly, as an intermediate step by dvipdf). Then it is
1347 useful to force output to be of the .dvi format by inserting \pdfout‐
1348 put=0 in the preamble of the document.
1349
1350 Another example is where the document uses graphics file of the .pdf,
1351 .jpg, and png types. With the default setting for the graphicx pack‐
1352 age, these can be processed in compilation to .pdf but not with compi‐
1353 lation to .dvi. In this case, it is useful to insert \pdfoutput=1 in
1354 the preamble of the document to force compilation to .pdf output for‐
1355 mat.
1356
1357 In all of these cases, it is needed that latexmk has to adjust its pro‐
1358 cessing to deal with a mismatch between the actual output format (out
1359 of .pdf, .dvi, .xdv) and the initially expected output, if possible.
1360 Latexmk does this provided the following conditions are met.
1361
1362 The first is that latexmk's $allow_switch configuration variable is set
1363 to a non-zero value as it is by default. If this variable is zero, a
1364 mismatch of filetypes in the compilation results in an erro.
1365
1366 The second condition for latexmk to be able to handle a change of out‐
1367 put type is that no explicit requests for .dvi or .ps output files are
1368 made. Explicit requests are by the -dvi and -ps, -print=dvi,
1369 -print=ps, -view=dvi, and -view=ps options, and by corresponding set‐
1370 tings of the $dvi_mode, $postscript_mode, $print_type, and $view con‐
1371 figuration variables. The print-type and view-type restrictions only
1372 apply when printing and viewing are explicitly requested, respectively.
1373 For this purpose, the use of the -pdfdvi and -pdfps options (and the
1374 corresponding setting of the $pdf_mode variable) does not count as an
1375 explicit request for the .dvi and .ps files; they are merely regarded
1376 as a request for making a .pdf file together with an initial proposal
1377 for the processing route to make it.
1378
1379 Note that when accommodating a change in output file type, there is
1380 involved a substantial change in the network of rules that latexmk uses
1381 in its actions. The second condition applied to accommodate a change
1382 is to avoid situations where the change in the rule network is too rad‐
1383 ical to be readily handled automatically.
1384
1385
1386
1388 In this section is explained which configuration files are read by
1389 latexmk. Subsequent sections "How to Set Variables in Initialization
1390 Files", "Format of Command Specifications", "List of Configuration
1391 Variables Usable in Initialization Files", "Custom Dependencies", and
1392 "Advanced Configuration" give details on what can be configured and
1393 how.
1394
1395 Latexmk can be customized using initialization files, which are read at
1396 startup in the following order:
1397
1398 1) The system RC file, if it exists.
1399 On a UNIX system, latexmk searches for following places for its sys‐
1400 tem RC file, in the following order, and reads the first it finds:
1401 "/opt/local/share/latexmk/LatexMk",
1402 "/usr/local/share/latexmk/LatexMk",
1403 "/usr/local/lib/latexmk/LatexMk".
1404 On a Fedora system, it only looks for "/etc/latexmk.conf".
1405 On a MS-Windows system it looks for "C:\latexmk\LatexMk".
1406 On a cygwin system (i.e., a MS-Windows system in which Perl is that
1407 of cygwin), latexmk reads the first it finds of
1408 "/cygdrive/c/latexmk/LatexMk",
1409 "/opt/local/share/latexmk/LatexMk",
1410 "/usr/local/share/latexmk/LatexMk",
1411 "/usr/local/lib/latexmk/LatexMk".
1412
1413 In addition, it then tries the same set of locations, but with the file
1414 name replaced "LatexMk" replaced by "latexmkrc".
1415
1416 If the environment variable LATEXMKRCSYS is set, its value is used as
1417 the name of the system RC file, instead of any of the above.
1418
1419 2) The user's RC file, if it exists. This can be in one of two places.
1420 The traditional one is ".latexmkrc" in the user's home directory. The
1421 other possibility is "latexmk/latexmkrc" in the user's XDG configura‐
1422 tion home directory. The actual file read is the first of "$XDG_CON‐
1423 FIG_HOME/latexmk/latexmkrc" or "$HOME/.latexmkrc" which exists. (See
1424 https://specifications.freedesktop.org/basedir-spec/basedir-spec-lat‐
1425 est.html for details on the XDG Base Directory Specification.)
1426
1427 Here $HOME is the user's home directory. [Latexmk determines the
1428 user's home directory as follows: It is the value of the environment
1429 variable HOME, if this variable exists, which normally is the case on
1430 UNIX-like systems (including Linux and OS-X). Otherwise the environ‐
1431 ment variable USERPROFILE is used, if it exists, which normally is the
1432 case on MS-Windows systems. Otherwise a blank string is used instead of
1433 $HOME, in which case latexmk does not look for an RC file in it.]
1434
1435 $XDG_CONFIG_HOME is the value of the environment variable XDG_CON‐
1436 FIG_HOME if it exists. If this environment variable does not exist,
1437 but $HOME is non-blank, then $XDG_CONFIG_HOME is set to the default
1438 value of $HOME/.config. Otherwise $XDG_CONFIG_HOME is blank, and
1439 latexmk does not look for an RC file under it.
1440
1441
1442 3) The RC file in the current working directory. This file can be
1443 named either "latexmkrc" or ".latexmkrc", and the first of these to be
1444 found is used, if any.
1445
1446 4) Any RC file(s) specified on the command line with the -r option.
1447
1448 Each RC file is a sequence of Perl commands. Naturally, a user can use
1449 this in creative ways. But for most purposes, one simply uses a
1450 sequence of assignment statements that override some of the built-in
1451 settings of Latexmk. Straightforward cases can be handled without
1452 knowledge of the Perl language by using the examples in this document
1453 as templates. Comment lines are introduced by the "#" character.
1454
1455 Note that command line options are obeyed in the order in which they
1456 are written; thus any RC file specified on the command line with the -r
1457 option can override previous options but can be itself overridden by
1458 later options on the command line. There is also the -e option, which
1459 allows initialization code to be specified in latexmk's command line.
1460
1461 For possible examples of code for in an RC file, see the directory
1462 example_rcfiles in the distribution of latexmk (e.g., at http://mir‐
1463 ror.ctan.org/support/latexmk/example_rcfiles).
1464
1465
1467 The important variables that can be configured are described in the
1468 section "List of configuration variables usable in initialization
1469 files". (See the earlier section "Configuration/Initialization (rc)
1470 Files" for the files where the configurations are done.) Syntax for
1471 setting these variables is of the following forms:
1472
1473 $bibtex = 'bibtex %O %B';
1474
1475 for the setting of a string variable,
1476
1477 $preview_mode = 1;
1478
1479 for the setting of a numeric variable, and
1480
1481 @default_files = ('paper', 'paper1');
1482
1483 for the setting of an array of strings. It is possible to append an
1484 item to an array variable as follows:
1485
1486 push @default_files, 'paper2';
1487
1488 Note that simple "scalar" variables have names that begin with a $
1489 character and array variables have names that begin with a @ character.
1490 Each statement ends with a semicolon.
1491
1492 Strings should be enclosed in single quotes. (You could use double
1493 quotes, as in many programming languages. But then the Perl program‐
1494 ming language brings into play some special rules for interpolating
1495 variables into strings. People not fluent in Perl will want to avoid
1496 these complications.)
1497
1498 You can do much more complicated things, but for this you will need to
1499 consult a manual for the Perl programming language.
1500
1501
1502
1503
1505 Some of the variables set the commands that latexmk uses for carrying
1506 out its work, for example to generate a .dvi file from a .tex file or
1507 to view a postscript file. This section describes some important fea‐
1508 tures of how the commands are specified. (Note that some of the possi‐
1509 bilities listed here do not apply to the $kpsewhich variable; see its
1510 documentation.)
1511
1512 Placeholders: Supposed you wanted latexmk to use the command elatex in
1513 place of the regular latex command, and suppose moreover that you
1514 wanted to give it the option "--shell-escape". You could do this by
1515 the following setting:
1516
1517 $latex = 'elatex --shell-escape %O %S';
1518
1519 The two items starting with the % character are placeholders. These
1520 are substituted by appropriate values before the command is run. Thus
1521 %S will be replaced by the source file that elatex will be applied to,
1522 and %O will be replaced by any options that latexmk has decided to use
1523 for this command. (E.g., if you used the -silent option in the invoca‐
1524 tion of latexmk, it results in the replacement of %O by "-interac‐
1525 tion=batchmode".)
1526
1527 The available placeholders are:
1528
1529 %A basename of the main tex file. Unlike %R, this is unaffected by
1530 the setting of a jobname by the -jobname option or the $jobname
1531 configuration value.
1532
1533 %B base of filename for current command. E.g., if a postscript
1534 file document.ps is being made from the dvi file document.dvi,
1535 then the basename is document.
1536
1537 %D destination file (e.g., the name of the postscript file when
1538 converting a dvi file to postscript).
1539
1540 %O options
1541
1542 %P If the variable $pre_tex_code is non-empty, then %P is substi‐
1543 tuted by the contents of $pre_tex_code followed by
1544 \input{SOURCE}, where SOURCE stands for the name of the source
1545 file. Appropriate quoting is done. This enables TeX code to be
1546 passed to one of the *latex engines to be executed before the
1547 source file is read.
1548
1549 If the variable $pre_tex_code is the empty string, then %P is
1550 equivalent to %S.
1551
1552 %R root filename. This is the base name for the main tex file.
1553
1554 By default this is the basename of the main tex file. However
1555 the value can be changed by the use of the -jobname option or
1556 the $jobname configuration variable.
1557
1558 %S source file (e.g., the name of the dvi file when converting a
1559 .dvi file to ps).
1560
1561 %T The name of the primary tex file.
1562
1563 %U If the variable $pre_tex_code is non-empty, then its value is
1564 substituted for %U (appropriately quoted). Otherwise it is
1565 replaced by a null string.
1566
1567 %Y Name of directory for auxiliary output files (see the configura‐
1568 tion variable $aux_dir). A directory separation character ('/')
1569 is appended if $aux_dir is non-empty and does not end in a suit‐
1570 able character, with suitable characters being those appropriate
1571 to UNIX and MS-Windows, i.e., ':', '/' and '\'. Note that if
1572 after initialization, $out_dir is set, but $aux_dir is not set
1573 (i.e., it is blank), then latexmk sets $aux_dir to the same
1574 value $out_dir.
1575
1576 %Z Name of directory for output files (see the configuration vari‐
1577 able $out_dir). A directory separation character ('/') is
1578 appended if $out_dir is non-empty and does not end in a suitable
1579 character, with suitable characters being those appropriate to
1580 UNIX and MS-Windows, i.e., ':', '/' and '\'.
1581
1582 If for some reason you need a literal % character in your string not
1583 subject to the above rules, use "%%".
1584
1585 Appropriate quoting will be applied to the filename substitutions, so
1586 you mustn't supply them yourself even if the names of your files have
1587 spaces in them. (But if your TeX filenames have spaces in them, beware
1588 that some older versions of the TeX program cannot correctly handle
1589 filenames containing spaces.) In case latexmk's quoting does not work
1590 correctly on your system, you can turn it off -- see the documentation
1591 for the variable $quote_filenames.
1592
1593 The distinction between %B and %R needs a bit of care, since they are
1594 often the same, but not always. For example on a simple document, the
1595 basename of a bibtex run is the same as for the texfile. But in a doc‐
1596 ument with several bibliographies, the bibliography files will have a
1597 variety of names. Since bibtex is invoked with the basename of the
1598 bibliography file, the setting for the bibtex command should therefore
1599 be
1600
1601 $bibtex = 'bibtex %O %B';
1602
1603 Generally, you should use %B rather than %R. Similarly for most pur‐
1604 poses, the name %T of the primary texfile is not a useful placeholder.
1605
1606 See the default values in the section "List of configuration variables
1607 usable in initialization files" for what is normally the most appropri‐
1608 ate usage.
1609
1610 If you omit to supply any placeholders whatever in the specification of
1611 a command, latexmk will supply what its author thinks are appropriate
1612 defaults. This gives compatibility with configuration files for previ‐
1613 ous versions of latexmk, which didn't use placeholders.
1614
1615 "Detaching" a command: Normally when latexmk runs a command, it waits
1616 for the command to run to completion. This is appropriate for commands
1617 like latex, of course. But for previewers, the command should normally
1618 run detached, so that latexmk gets the previewer running and then
1619 returns to its next task (or exits if there is nothing else to do). To
1620 achieve this effect of detaching a command, you need to precede the
1621 command name with "start ", as in
1622
1623 $dvi_previewer = 'start xdvi %O %S';
1624
1625 This will be translated to whatever is appropriate for your operating
1626 system.
1627
1628 Notes: (1) In some circumstances, latexmk will always run a command
1629 detached. This is the case for a previewer in preview continuous mode,
1630 since otherwise previewing continuously makes no sense. (2) This pre‐
1631 cludes the possibility of running a command named start. (3) If the
1632 word start occurs more than once at the beginning of the command
1633 string, that is equivalent to having just one. (4) Under cygwin, some
1634 complications happen, since cygwin amounts to a complicated merging of
1635 UNIX and MS-Windows. See the source code for how I've handled the
1636 problem.
1637
1638 Command names containing spaces: Under MS-Windows it is common that the
1639 name of a command includes spaces, since software is often installed in
1640 a subdirectory of "C:\Program Files". Such command names should be
1641 enclosed in double quotes, as in
1642
1643 $lpr_pdf = '"c:/Program Files/Ghostgum/gsview/gsview32.exe" /p
1644 %S';
1645 $pdf_previewer = 'start "c:/Program Files/SumatraPDF/Suma‐
1646 traPDF.exe" %O %S';
1647 $pdf_previewer = 'start "c:/Program Files/SumatraPDF (x86)/Suma‐
1648 traPDF.exe" %O %S';
1649
1650
1651 (Note about the above example: Under MS-Windows forward slashes are
1652 equivalent to backslashes in a filename under almost all circumstances,
1653 provided that the filename is inside double quotes. It is easier to
1654 use forward slashes in examples like the one above, since then one does
1655 not have to worry about the rules for dealing with forward slashes in
1656 strings in the Perl language.)
1657
1658 Command names under Cygwin: If latexmk is executed by Cygwin's Perl,
1659 be particularly certain that pathnames in commands have forward slashes
1660 not the usual backslashes for the separator of pathname components.
1661 See the above examples. Backslashes often get misinterpreted by the
1662 Unix shell used by Cygwin's Perl to execute external commands. Forward
1663 slashes don't suffer from this problem, and (when quoted, as above) are
1664 equally acceptable to MS-Windows.
1665
1666 Using MS-Windows file associations: A useful trick under modern ver‐
1667 sions of MS-Windows (e.g., WinXP) is to use just the command 'start' by
1668 itself:
1669
1670 $dvi_previewer = 'start %S';
1671
1672 Under MS-Windows, this will cause to be run whatever program the system
1673 has associated with dvi files. (The same applies for a postscript
1674 viewer and a pdf viewer.) But note that this trick is not always suit‐
1675 able for the pdf previwer, if your system has acroread for the default
1676 pdf viewer. As explained elsewhere, acroread under MS-Windows does not
1677 work well with latex and latexmk, because acroread locks the pdf file.
1678
1679 Not using a certain command: If a command is not to be run, the command
1680 name NONE is used, as in
1681
1682 $lpr = 'NONE lpr';
1683
1684 This typically is used when an appropriate command does not exist on
1685 your system. The string after the "NONE" is effectively a comment.
1686
1687 Options to commands: Setting the name of a command can be used not only
1688 for changing the name of the command called, but also to add options to
1689 command. Suppose you want latexmk to use latex with source specials
1690 enabled. Then you might use the following line in an initialization
1691 file:
1692
1693 $latex = 'latex --src-specials %O %S';
1694
1695 Running a subroutine instead of an external command: Use a specifica‐
1696 tion starting with "internal", as in
1697
1698 $latex = 'internal mylatex %O %S';
1699 sub mylatex {
1700 my @args = @_;
1701 # Possible preprocessing here
1702 return system 'latex', @args;
1703 }
1704
1705 For some of the more exotic possibilities that then become available,
1706 see the section "ADVANCED CONFIGURATION: Some extra resources and
1707 advanced tricks". Also see some of the examples in the directory exam‐
1708 ple_rcfiles in the latexmk distribution.
1709
1710 Advanced tricks: Normally one specifies a single command for the com‐
1711 mands invoked by latexmk. Naturally, if there is some complicated
1712 additional processing you need to do in your special situation, you can
1713 write a script (or batch file) to do the processing, and then configure
1714 latexmk to use your script in place of the standard program.
1715
1716 You can also use a Perl subroutine instead of a script -- see above.
1717 This is generally the most flexible and portable solution.
1718
1719 It is also possible to configure latexmk to run multiple commands. For
1720 example, if when running pdflatex to generate a pdf file from a tex
1721 file you need to run another program after pdflatex to perform some
1722 extra processing, you could do something like:
1723
1724 $pdflatex = 'pdflatex --shell-escape %O %S; pst2pdf_for_latexmk
1725 %B';
1726
1727 This definition assumes you are using a UNIX-like system (which
1728 includes Linux and OS-X), so that the two commands to be run are sepa‐
1729 rated by the semicolon in the middle of the string.
1730
1731 If you are using MS-Windows, you would replace the above line by
1732
1733 $pdflatex = 'cmd /c pdflatex --shell-escape %O %S'
1734 . '&& pst2pdf_for_latexmk %B';
1735
1736 Here, the UNIX command separator ; is replaced by &&. In addition,
1737 there is a problem that some versions of Perl on MS-Windows do not obey
1738 the command separator; this problem is overcome by explicitly invoking
1739 the MS-Windows command-line processor cmd.exe.
1740
1741
1743 In this section are specified the variables whose values can be
1744 adjusted to configure latexmk. (See the earlier section "Configura‐
1745 tion/Initialization (rc) Files" for the files where the configurations
1746 are done.)
1747
1748 Default values are indicated in brackets. Note that for variables that
1749 are boolean in character, concerning whether latexmk does or does not
1750 behave in a certain way, a non-zero value, normally 1, indicates true,
1751 i.e., the behavior occurs, while a zero value indicates a false value,
1752 i.e., the behavior does not occur.
1753
1754
1755 $allow_switch [1]
1756
1757 This controls what happens when the output extension of latex,
1758 pdflatex, lualatex or xelatex differs from what is expected.
1759 (The possible extensions are .dvi, .pdf, .xdv.) This can happen
1760 with the use of the \pdfoutput macro in a document compiled
1761 under latex or pdflatex, or with the use of the \outputmode
1762 macro under lualatex. It can also happen with certain kinds of
1763 incorrect configuration.
1764
1765 In such a case, latexmk can appropriately adjust its network of
1766 rules. The adjustment is made if $allow_switch is on, and if no
1767 request for a dvi or ps file has been made.
1768
1769 See the section ALLOWING FOR CHANGE OF OUTPUT EXTENSION.
1770
1771
1772 $always_view_file_via_temporary [0]
1773 Whether .ps and .pdf files are initially to be made in a tempo‐
1774 rary directory and then moved to the final location. (This
1775 applies to dvips, dvipdf, and ps2pdf operations, and the filter‐
1776 ing operators on .dvi and .ps files. It does not apply to
1777 pdflatex, unfortunately, since pdflatex provides no way of spec‐
1778 ifying a chosen name for the output file.)
1779
1780 This use of a temporary file solves a problem that the making of
1781 these files can occupy a substantial time. If a viewer (notably
1782 gv) sees that the file has changed, it may read the new file
1783 before the program writing the file has not yet finished its
1784 work, which can cause havoc.
1785
1786 See the $pvc_view_file_via_temporary variable for a setting that
1787 applies only if preview-continuous mode (-pvc option) is used.
1788 See $tmpdir for the setting of the directory where the temporary
1789 file is created.
1790
1791
1792 $analyze_input_log_always [1]
1793
1794 After a run of latex (etc), always analyze .log for input files
1795 in the <...> and (...) constructions. Otherwise, only do the
1796 analysis when fls file doesn't exist or is out of date.
1797
1798 Under normal circumstances, the data in the fls file is reli‐
1799 able, and the test of the log file gets lots of false positives;
1800 usually $analyze_input_log_always is best set to zero. But the
1801 test of the log file is needed at least in the following situa‐
1802 tion: When a user needs to persuade latexmk that a certain file
1803 is a source file, and latexmk doesn't otherwise find it. Then
1804 the user can write code that causes a line with (...) to be
1805 written to log file. One important case is for lualatex, which
1806 doesn't always generate lines in the .fls file for input lua
1807 files. (The situation with lualatex is HIGHLY version depen‐
1808 dent, e.g., there was a big change between TeXLive 2016 and
1809 TeXLive 2017.)
1810
1811 To keep backward compatibility with older versions of latexmk,
1812 the default is to set $analyze_input_log_always to 1.
1813
1814
1815 $auto_rc_use [1]
1816 Whether to automatically read the standard initialization (rc)
1817 files, which are the system RC file, the user's RC file, and the
1818 RC file in the current directory. The command line option -norc
1819 can be used to turn this setting off. Each RC file could also
1820 turn this setting off, i.e., it could set $auto_rc_use to zero
1821 to prevent automatic reading of the later RC files.
1822
1823 This variable does not affect the reading of RC files specified
1824 on the command line by the -r option.
1825
1826 $aux_dir [""]
1827 The directory in which auxiliary files (aux, log, etc) are to be
1828 written by a run of (pdf)latex. If this variable is not set,
1829 but $out_dir is set, then $aux_dir is set to $out_dir, which is
1830 the directory to which general output files are to be written.
1831
1832 Important note: The effect of $aux_dir, if different from
1833 $out_dir, is achieved by giving (pdf)latex the -aux-directory.
1834 Currently (Dec. 2011 and later) this only works on the MiKTeX
1835 version of (pdf)latex.
1836
1837 See also the documentation of $out_dir for some complications on
1838 what directory names are suitable.
1839
1840 If you also use the -cd option, and $out_dir (or $aux_dir) con‐
1841 tains a relative path, then the path is interpreted relative to
1842 the document directory.
1843
1844 $banner [0]
1845 If nonzero, the banner message is printed across each page when
1846 converting the dvi file to postscript. Without modifying the
1847 variable $banner_message, this is equivalent to specifying the
1848 -d option.
1849
1850 Note that if $banner is nonzero, the $postscript_mode is assumed
1851 and the postscript file is always generated, even if it is newer
1852 than the dvi file.
1853
1854 $banner_intensity [0.95]
1855 Equivalent to the -bi option, this is a decimal number between 0
1856 and 1 that specifies how dark to print the banner message. 0 is
1857 black, 1 is white. The default is just right if your toner car‐
1858 tridge isn't running too low.
1859
1860 $banner_message ["DRAFT"]
1861 The banner message to print across each page when converting the
1862 dvi file to postscript. This is equivalent to the -bm option.
1863
1864 $banner_scale [220.0]
1865 A decimal number that specifies how large the banner message
1866 will be printed. Experimentation is necessary to get the right
1867 scale for your message, as a rule of thumb the scale should be
1868 about equal to 1100 divided by the number of characters in the
1869 message. The Default is just right for 5 character messages.
1870 This is equivalent to the -bs option.
1871
1872 @BIBINPUTS
1873 This is an array variable, now mostly obsolete, that specifies
1874 directories where latexmk should look for .bib files. By
1875 default it is set from the BIBINPUTS environment variable of the
1876 operating system. If that environment variable is not set, a
1877 single element list consisting of the current directory is set.
1878 The format of the directory names depends on your operating sys‐
1879 tem, of course. Examples for setting this variable are:
1880
1881 @BIBINPUTS = ( ".", "C:\\bibfiles" );
1882 @BIBINPUTS = ( ".", "\\server\bibfiles" );
1883 @BIBINPUTS = ( ".", "C:/bibfiles" );
1884 @BIBINPUTS = ( ".", "//server/bibfiles" );
1885 @BIBINPUTS = ( ".", "/usr/local/texmf/bibtex/bib" );
1886
1887 Note that under MS Windows, either a forward slash "/" or a
1888 backward slash "\" can be used to separate pathname components,
1889 so the first two and the second two examples are equivalent.
1890 Each backward slash should be doubled to avoid running afoul of
1891 Perl's rules for writing strings.
1892
1893 Important note: This variable is now mostly obsolete in the cur‐
1894 rent version of latexmk, since it has a better method of search‐
1895 ing for files using the kpsewhich command. However, if your
1896 system is an unusual one without the kpsewhich command, you may
1897 need to set the variable @BIBINPUTS.
1898
1899 $biber ["biber %O %S"]
1900 The biber processing program.
1901
1902 $biber_silent_switch ["--onlylog"]
1903 Switch(es) for the biber processing program when silent mode is
1904 on.
1905
1906 $bibtex ["bibtex %O %S"]
1907 The BibTeX processing program.
1908
1909 $bibtex_fudge [1]
1910 When using bibtex, whether to take special action to allow bib‐
1911 tex to work when $out_dir or $aux_dir is specified. In May
1912 2018, there was planned an update to bibtex to correct a bug,
1913 after that update, the special action will no longer be
1914 required.
1915
1916 $bibtex_silent_switch ["-terse"]
1917 Switch(es) for the BibTeX processing program when silent mode is
1918 on.
1919
1920 $bibtex_use [1]
1921 Under what conditions to run bibtex or biber. When latexmk dis‐
1922 covers from the log file that one (or more) bibtex/biber-gener‐
1923 ated bibliographies are used, it can run bibtex or biber when‐
1924 ever it appears necessary to regenerate the bbl file(s) from
1925 their source bib database file(s). But sometimes, the bib
1926 file(s) are not available (e.g., for a document obtained from an
1927 external archive), but the bbl files are provided. In that case
1928 use of bibtex or biber will result in incorrect overwriting of
1929 the precious bbl files. The variable $bibtex_use controls
1930 whether this happens, and also controls whether or not .bbl
1931 files are deleted in a cleanup operation.
1932
1933 The possible values of $bibtex_use are:
1934 0: never use BibTeX or biber; never delete .bbl files in a
1935 cleanup.
1936 1: only use bibtex or biber if the bib files exist; never
1937 delete .bbl files in a cleanup.
1938 1.5: only use bibtex or biber if the bib files exist; condi‐
1939 tionally delete .bbl files in a cleanup (i.e., delete them only
1940 when the bib files all exist).
1941 2: run bibtex or biber whenever it appears necessary to update
1942 the bbl files, without testing for the existence of the bib
1943 files; always delete .bbl files in a cleanup.
1944
1945 Note that the value 1.5 does not work properly if the document
1946 uses biber instead of bibtex. (There's a long story why not.)
1947
1948
1949 $cleanup_includes_cusdep_generated [0]
1950 If nonzero, specifies that cleanup also deletes files that are
1951 generated by custom dependencies. (When doing a clean up, e.g.,
1952 by use of the -C option, custom dependencies are those listed in
1953 the .fdb_latexmk file from a previous run.)
1954
1955 $cleanup_includes_generated [0]
1956 If nonzero, specifies that cleanup also deletes files that are
1957 detected in the fls file (or failing that, in log file) as being
1958 generated. It will also include files made from these first
1959 generation generated files.
1960
1961 This operation is somewhat dangerous, and can have unintended
1962 consequences, since the files to be deleted are determined from
1963 a file created by (pdf)latex, which can contain erroneous infor‐
1964 mation. Therefore this variable is turned off by default, and
1965 then files to be deleted are restricted to those explictly spec‐
1966 ified by patterns configured in the variables clean_ext,
1967 clean_full_ext, and @generated_exts, together with those very
1968 standard cases that are hardwired into latexmk (e.g., .log
1969 files).
1970
1971 $cleanup_mode [0]
1972 If nonzero, specifies cleanup mode: 1 for full cleanup, 2 for
1973 cleanup except for .dvi, .ps and .pdf files, 3 for cleanup
1974 except for dep and aux files. (There is also extra cleaning as
1975 specified by the $clean_ext, $clean_full_ext and @generated_exts
1976 variables.)
1977
1978 This variable is equivalent to specifying one of the -c or -C
1979 options. But there should be no need to set this variable from
1980 an RC file.
1981
1982 $clean_ext [""]
1983 Extra extensions of files for latexmk to remove when any of the
1984 clean-up options (-c or -C) is selected. The value of this
1985 variable is a string containing the extensions separated by spa‐
1986 ces.
1987
1988 It is also possible to specify a more general pattern of file to
1989 be deleted, by using the place holder %R, as in commands, and it
1990 is also possible to use wildcards. Thus setting
1991
1992 $clean_ext = "out %R-blx.bib %R-figures*.log pythontex-
1993 files-%R/*";
1994
1995 in an initialization file will imply that when a clean-up opera‐
1996 tion is specified, not only is the standard set of files
1997 deleted, but also files of the form FOO.out, FOO-blx.bib, %R-
1998 figures*.log, and pythontex-files-FOO/*, where FOO stands for
1999 the basename of the file being processed (as in FOO.tex).
2000
2001 The files to be deleted are relative to the directory specified
2002 by $aux_dir. (Note that if $out_dir but not $aux_dir is set,
2003 then in its initialization, latexmk sets $aux_dir equal to
2004 $out_dir. A normal situation is therefore that $aux_dir equals
2005 $out_dir, which is the only case supported by TeXLive, unlike
2006 MiKTeX.)
2007
2008 The filenames specfied for a clean-up operation can refer not
2009 only to regular files but also to directories. Directories are
2010 only deleted if they are empty. An example of an application is
2011 to pythontex, which creates files in a particular directory.
2012 You can arrange to remove both the files and the directory by
2013 setting
2014
2015 $clean_ext = "pythontex-files-%R pythontex-files-%R";
2016
2017 See also the variable @generated_exts.
2018
2019 $clean_full_ext [""]
2020 Extra extensions of files for latexmk to remove when the -C
2021 option is selected, i.e., extensions of files to remove when the
2022 .dvi, etc files are to be cleaned-up.
2023
2024 More general patterns are allowed, as for $clean_ext.
2025
2026 The files specified by $clean_full_ext to be deleted are rela‐
2027 tive to the directory specified by $out_dir.
2028
2029
2030 $compiling_cmd [""], $failure_cmd [""], $warning_cmd [""], $success_cmd
2031 [""]
2032
2033 These variables specify commands that are executed at certain
2034 points of compilations. One motivation for their existance is
2035 to allow very useful convenient visual indications of compila‐
2036 tion status even when the window receiving the screen output of
2037 the compilation is hidden. This is particularly useful in pre‐
2038 view-continuous mode.
2039
2040 The commands are executed at the following points: $compil‐
2041 ing_cmd at the start of compilation, $success_cmd at the end of
2042 a completely successful compilation, $failure_cmd at the end of
2043 an unsuccessful compilation, $warning_cmd at the of an otherwise
2044 successful compilation that gives warnings about undefined cita‐
2045 tions or references or about multiply defined references. If any
2046 of above variables is undefined or blank (the default situa‐
2047 tion), then the corresponding command is not executed.
2048
2049 However, when $warning_cmd is not set, then in the case of a
2050 compilation with warnings about references or citations, but
2051 with no other error, one or other of $success_cmd or $fail‐
2052 ure_cmd is used (if it is set) according to the setting of
2053 $warnings_as_errors.
2054
2055 An example of a simple setting of these variables is as follows
2056
2057 $compiling_cmd = "xdotool search --name \"%D\" set_window
2058 --name \"%D compiling\"";
2059 $success_cmd = "xdotool search --name \"%D\" set_window
2060 --name \"%D OK\"";
2061 $warning_cmd = "xdotool search --name \"%D\" ".
2062 "set_window --name \"%D CITE/REF ISSUE\"";
2063 $failure_cmd = "xdotool search --name \"%D\" set_window
2064 --name \"%D FAILURE\"";
2065
2066 These assume that the program xdotool is installed, that the
2067 previewer is using an X-Window system for display, and that the
2068 title of the window contains the name of the displayed file, as
2069 it normally does. When the commands are executed, the place‐
2070 holder string %D is replaced by the name of the destination
2071 file, which is the previewed file. The above commands result in
2072 an appropriate string being appended to the filename in the win‐
2073 dow title: " compiling", " OK", or " FAILURE".
2074
2075 Other placeholders that can be used are %S, %T, and %R, with %S
2076 and %T normally being identical. These can be useful for a com‐
2077 mand changing the title of the edit window. The visual indica‐
2078 tion in a window title can useful, since the user does not have
2079 to keep shifting attention to the (possibly hidden) compilation
2080 window to know the status of the compilation.
2081
2082 More complicated situations can best be handled by defining a
2083 Perl subroutine to invoke the necessary commands, and using the
2084 "internal" keyword in the definitions to get the subroutine to
2085 be invoked. (See the section "Format of Command Specifications"
2086 for how to do this.)
2087
2088 Naturally, the above settings that invoke the xdotool program
2089 are only applicable when the X-Window system is used for the
2090 relevant window(s). For other cases, you will have to find what
2091 software solutions are available.
2092
2093
2094 @cus_dep_list [()]
2095 Custom dependency list -- see section on "Custom Dependencies".
2096
2097 @default_excluded_files [()]
2098 When latexmk is invoked with no files specified on the command
2099 line, then, by default, it will process all files in the current
2100 directory with the extension .tex. (In general, it will process
2101 the files specified in the @default_files variable.)
2102
2103 But sometimes you want to exclude particular files from this
2104 default list. In that case you can specify the excluded files
2105 in the array @default_excluded_files. For example if you wanted
2106 to process all .tex files with the exception of common.tex,
2107 which is a not a standard alone LaTeX file but a file input by
2108 some or all of the others, you could do
2109
2110 @default_files = ("*.tex");
2111
2112 @default_excluded_files = ("common.tex");
2113
2114 If you have a variable or large number of files to be processed,
2115 this method saves you from having to list them in detail in
2116 @default_files and having to update the list every time you
2117 change the set of files to be processed.
2118
2119 Notes: 1. This variable has no effect except when no files are
2120 specified on the latexmk command line. 2. Wildcards are allowed
2121 in @default_excluded_files.
2122
2123 @default_files [("*.tex")]
2124 Default list of files to be processed.
2125
2126 If no filenames are specified on the command line, latexmk pro‐
2127 cesses all tex files specified in the @default_files variable,
2128 which by default is set to all tex files ("*.tex") in the cur‐
2129 rent directory. This is a convenience: just run latexmk and it
2130 will process an appropriate set of files. But sometimes you
2131 want only some of these files to be processed. In this case you
2132 can list the files to be processed by setting @default_files in
2133 an initialization file (e.g., the file "latexmkrc" in the cur‐
2134 rent directory). Then if no files are specified on the command
2135 line then the files you specify by setting @default_files are
2136 processed.
2137
2138 Three examples:
2139
2140 @default_files = ("paper_current");
2141
2142 @default_files = ("paper1", "paper2.tex");
2143
2144 @default_files = ("*.tex", "*.dtx");
2145
2146 Note that more than file may be given, and that the default
2147 extension is ".tex". Wild cards are allowed. The parentheses
2148 are because @default_files is an array variable, i.e., a
2149 sequence of filename specifications is possible.
2150
2151 If you want latexmk to process all .tex files with a few excep‐
2152 tions, see the @default_excluded_files array variable.
2153
2154 $dependents_phony [0]
2155 If a list of dependencies is output, this variable determines
2156 whether to include a phony target for each source file. If you
2157 use the dependents list in a Makefile, the dummy rules work
2158 around errors make gives if you remove header files without
2159 updating the Makefile to match.
2160
2161 $dependents_list [0]
2162 Whether to display a list(s) of dependencies at the end of a
2163 run.
2164
2165 $deps_file ["-"]
2166 Name of file to receive list(s) of dependencies at the end of a
2167 run, to be used if $dependesnt_list is set. If the filename is
2168 "-", then the dependency list is set to stdout (i.e., normally
2169 the screen).
2170
2171 $do_cd [0]
2172 Whether to change working directory to the directory specified
2173 for the main source file before processing it. The default
2174 behavior is not to do this, which is the same as the behavior of
2175 latex and pdflatex programs. This variable is set by the -cd
2176 and -cd- options on latexmk's command line.
2177
2178 $dvi_filter [empty]
2179 The dvi file filter to be run on the newly produced dvi file
2180 before other processing. Equivalent to specifying the -dF
2181 option.
2182
2183 $dvi_mode [See below for default]
2184 If nonzero, generate a dvi version of the document. Equivalent
2185 to the -dvi option.
2186
2187 The variable $dvi_mode defaults to 0, but if no explicit
2188 requests are made for other types of file (postscript, pdf),
2189 then $dvi_mode will be set to 1. In addition, if a request for
2190 a file for which a .dvi file is a prerequisite, then $dvi_mode
2191 will be set to 1.
2192
2193 $dvi_previewer ["start xdvi %O %S" under UNIX]
2194 The command to invoke a dvi-previewer. [Under MS-Windows the
2195 default is "start"; then latexmk arranges to use the MS-Windows
2196 start program, which will cause to be run whatever command the
2197 system has associated with .dvi files.]
2198
2199 Important note: Normally you will want to have a previewer run
2200 detached, so that latexmk doesn't wait for the previewer to ter‐
2201 minate before continuing its work. So normally you should pre‐
2202 fix the command by "start ", which flags to latexmk that it
2203 should do the detaching of the previewer itself (by whatever
2204 method is appropriate to the operating system). But sometimes
2205 letting latexmk do the detaching is not appropriate (for a vari‐
2206 ety of non-trivial reasons), so you should put the "start " bit
2207 in yourself, whenever it is needed.
2208
2209 $dvi_previewer_landscape ["start xdvi %O %S"]
2210 The command to invoke a dvi-previewer in landscape mode. [Under
2211 MS-Windows the default is "start"; then latexmk arranges to use
2212 the MS-Windows start program, which will cause to be run what‐
2213 ever command the system has associated with .dvi files.]
2214
2215 $dvipdf ["dvipdf %O %S %D"]
2216 Command to convert .dvi to .pdf file. A common reconfiguration
2217 is to use the dvipdfm command, which needs its arguments in a
2218 different order:
2219
2220 $dvipdf = "dvipdfm %O -o %D %S";
2221
2222 WARNING: The default dvipdf script generates pdf files with
2223 bitmapped fonts, which do not look good when viewed by acroread.
2224 That script should be modified to give dvips the options "-P
2225 pdf" to ensure that type 1 fonts are used in the pdf file.
2226
2227 $dvipdf_silent_switch ["-q"]
2228 Switch(es) for dvipdf program when silent mode is on.
2229
2230 N.B. The standard dvipdf program runs silently, so adding the
2231 silent switch has no effect, but is actually innocuous. But if
2232 an alternative program is used, e.g., dvipdfmx, then the silent
2233 switch has an effect. The default setting is correct for
2234 dvipdfm and dvipdfmx.
2235
2236 $dvips ["dvips %O -o %D %S"]
2237 The program to used as a filter to convert a .dvi file to a .ps
2238 file. If pdf is going to be generated from pdf, then the value
2239 of the $dvips_pdf_switch variable -- see below -- will be
2240 included in the options substituted for "%O".
2241
2242 $dvips_landscape ["dvips -tlandscape %O -o %D %S"]
2243 The program to used as a filter to convert a .dvi file to a .ps
2244 file in landscape mode.
2245
2246 $dvips_pdf_switch ["-P pdf"]
2247 Switch(es) for dvips program when pdf file is to be generated
2248 from .ps file.
2249
2250 $dvips_silent_switch ["-q"]
2251 Switch(es) for dvips program when silent mode is on.
2252
2253 $dvi_update_command [""]
2254 When the dvi previewer is set to be updated by running a com‐
2255 mand, this is the command that is run. See the information for
2256 the variable $dvi_update_method for further information, and see
2257 information on the variable $pdf_update_method for an example
2258 for the analogous case of a pdf previewer.
2259
2260 $dvi_update_method [2 under UNIX, 1 under MS-Windows]
2261 How the dvi viewer updates its display when the dvi file has
2262 changed. The values here apply equally to the
2263 $pdf_update_method and to the $ps_update_method variables.
2264 0 => update is automatic,
2265 1=> manual update by user, which may only mean a mouse click
2266 on the viewer's window or may mean a more serious action.
2267 2 => Send the signal, whose number is in the variable
2268 $dvi_update_signal. The default value under UNIX is suitable
2269 for xdvi.
2270 3 => Viewer cannot do an update, because it locks the file.
2271 (As with acroread under MS-Windows.)
2272 4 => run a command to do the update. The command is speci‐
2273 fied by the variable $dvi_update_command.
2274
2275 See information on the variable $pdf_update_method for an exam‐
2276 ple of updating by command.
2277
2278 $dvi_update_signal [Under UNIX: SIGUSR1, which is a system-dependent
2279 value]
2280 The number of the signal that is sent to the dvi viewer when it
2281 is updated by sending a signal -- see the information on the
2282 variable $dvi_update_method. The default value is the one
2283 appropriate for xdvi on a UNIX system.
2284
2285 $failure_cmd [undefined]
2286 See the documentation for $compiling_cmd.
2287
2288 $fdb_ext ["fdb_latexmk"]
2289 The extension of the file which latexmk generates to contain a
2290 database of information on source files. You will not normally
2291 need to change this.
2292
2293 $filetime_causality_threshold [5]; $filetime_offset_report_threshold
2294 [30]. (Units of seconds.)
2295
2296 These variables control how latexmk deals with the following
2297 issue, which can affect the use of files that are on a remote
2298 filesystem (network share) instead of being on a file system
2299 local to the computer running latexmk. Almost users will not
2300 have to worry about these settings, and can ignore the following
2301 explanation.
2302
2303 In almost all situations, latexmk does not need to use the time
2304 stamps of the files it works with. However, there are a couple
2305 of situations when it needs to know whether a certain file was
2306 created in the current run of a program (e.g., (pdf)latex) or is
2307 a leftover file from a previous run. It does this by comparing
2308 the modification time of the file with the system time just
2309 before the program was started. If the modification time is ear‐
2310 lier than when the program was started, the file is a leftover
2311 file, which latexmk treats as if it were not created. If the
2312 filetime is at least the program start time, then it can be
2313 assumed that the file was created in the current run.
2314
2315 Unfortunately, this test can fail if the file is on a remote
2316 system, since its system time is not necessarily synchronized
2317 with that of the local system; the timestamps on the remote
2318 files are set by the remote system, not the local system. Gen‐
2319 erally, modern operating systems regularly synchronize their
2320 time with a server, so the non-synchronization is mostly small
2321 (a second or so, or a few seconds). But even a small difference
2322 can mess up latexmk's test.
2323
2324 Latexmk measures the time difference between the time on the two
2325 systems and compensates for this. But the measurement (in a
2326 system-independent way) is only accurate to a second or two. So
2327 latexmk allows for a threshold on the difference between file
2328 and system time before it concludes that a file is a leftover
2329 file from a previous run. The configuration variable $file‐
2330 time_causality_theshhold, which in units of seconds, specifies
2331 this threshold. Luckily high precision is not needed. The pre‐
2332 vious run is normally the previous run in a human run-edit-run
2333 cycle, and is at least many seconds back. A few seconds is
2334 therefore appropriate for the threshold, $filetime_causal‐
2335 ity_theshhold; it should be non-negative always, and should be
2336 bigger than 2 if a remote filesystem or network share is used.
2337
2338 If the difference in system times on the two systems is large,
2339 it normally indicates that at least one of the systems is mis‐
2340 configured. The variable $filetime_offset_report_threshold
2341 specifies the smallest size of the difference (or offset) in
2342 seconds between the times of the local and remote system beyond
2343 which the offset is reported. This is reported at the point in
2344 the latexmk's progress that it measures the offset. The report
2345 is made if silent mode is used and diagnostic mode is not on.
2346
2347
2348 $force_mode [0]
2349 If nonzero, continue processing past minor latex errors includ‐
2350 ing unrecognized cross references. Equivalent to specifying the
2351 -f option.
2352
2353 @generated_exts [( aux , bbl , idx , ind , lof , lot , out , toc ,
2354 $fdb_ext )]
2355 This contains a list of extensions for files that are generated
2356 during a LaTeX run and that are read in by LaTeX in later runs,
2357 either directly or indirectly.
2358
2359 This list specifies files known to be generated by latex (and
2360 pdflatex, etc). It is used in two ways: (a) The specified files
2361 are deleted in a cleanup operation (with the -c, -C, -CA, -g and
2362 -gg options), and (b) It affects the determination of whether a
2363 rerun of (pdf)LaTeX is needed after a run that gives an error.
2364
2365 (Concerning item (b): Normally, a change of a source file during
2366 a run should provoke a rerun. This includes a file generated by
2367 LaTeX, e.g., an aux file, that is read in on subsequent runs.
2368 But after a run that results in an error, a new run should not
2369 occur until the user has made a change in the files. But the
2370 user may have corrected an error in a source .tex file during
2371 the run. So latexmk needs to distinguish user-generated and
2372 automatically generated files; it determines the automatically
2373 generated files as those with extensions in the list in @gener‐
2374 ated_exts.)
2375
2376 A convenient way to add an extra extension to the list, without
2377 losing the already defined ones is to use a push command in the
2378 line in an RC file. E.g.,
2379
2380 push @generated_exts, "end";
2381
2382 adds the extension "end" to the list of predefined generated
2383 extensions. (This extension is used by the RevTeX package, for
2384 example.)
2385
2386 $go_mode [0]
2387 If nonzero, process files regardless of timestamps, and is then
2388 equivalent to the -g option.
2389
2390 %hash_calc_ignore_pattern
2391 !!!This variable is for experts only!!!
2392
2393 The general rule latexmk uses for determining when an extra run
2394 of some program is needed is that one of the source files has
2395 changed. But consider for example a latex package that causes
2396 an encapsulated postscript file (an "eps" file) to be made that
2397 is to be read in on the next run. The file contains a comment
2398 line giving its creation date and time. On the next run the
2399 time changes, latex sees that the eps file has changed, and
2400 therefore reruns latex. This causes an infinite loop, that is
2401 only terminated because latexmk has a limit on the number of
2402 runs to guard against pathological situations.
2403
2404 But the changing line has no real effect, since it is a comment.
2405 You can instruct latex to ignore the offending line as follows:
2406
2407 $hash_calc_ignore_pattern{'eps'} = '^%%CreationDate: ';
2408
2409 This creates a rule for files with extension .eps about lines to
2410 ignore. The left-hand side is a Perl idiom for setting an item
2411 in a hash. Note that the file extension is specified without a
2412 period. The value, on the right-hand side, is a string contain‐
2413 ing a regular expresssion. (See documentation on Perl for how
2414 they are to be specified in general.) This particular regular
2415 expression specifies that lines beginning with "%%CreationDate:
2416 " are to be ignored in deciding whether a file of the given
2417 extension .eps has changed.
2418
2419 There is only one regular expression available for each exten‐
2420 sion. If you need more one pattern to specify lines to ignore,
2421 then you need to combine the patterns into a single regular
2422 expression. The simplest method is separate the different sim‐
2423 ple patterns by a vertical bar character (indicating "alterna‐
2424 tion" in the jargon of regular expressions). For example,
2425
2426 $hash_calc_ignore_pattern{'eps'} = '^%%CreationDate:
2427 |^%%Title: ';
2428
2429 causes lines starting with either "^%%CreationDate: " or
2430 "^%%Title: " to be ignored.
2431
2432 It may happen that a pattern to be ignored is specified in, for
2433 example, in a system or user initialization file, and you wish
2434 to remove this in a file that is read later. To do this, you
2435 use Perl's delete function, e.g.,
2436
2437 delete $hash_calc_ignore_pattern{'eps'};
2438
2439
2440 $jobname [""]
2441
2442 This specifies the jobname, i.e., the basename that is used for
2443 generated files (.aux, .log, .dvi, .ps, .pdf, etc). If this
2444 variable is a null string, then the basename is the basename of
2445 the main tex file. (At present, the string in $jobname should
2446 not contain spaces.)
2447
2448 The placeholder '%A' is permitted. This will be substituted by
2449 the basename of the TeX file. The primary purpose is when a
2450 variety of tex files are to be processed, and you want to use a
2451 different jobname for each but one that is distinct for each.
2452 Thus if you wanted to compare compilations of a set of files on
2453 different operating systems, with distinct filenames for all the
2454 cases, you could set
2455
2456 $jobname = "%A-$^O";
2457
2458 in an initialization file. (Here $^O is a variable provided by
2459 perl that contains perl's name for the operating system.)
2460
2461 Suppose you had .tex files test1.tex and test2.tex. Then when
2462 you run
2463
2464 latexmk -pdf *.tex
2465
2466 both files will be compiled. The .aux, .log, and .pdf files
2467 will have basenames test1-MSWin32 ante test2-MSWin32 on a MS-
2468 Windows system, test1-darwin and test2-darwin on an OS-X system,
2469 and a variety of similar cases on linux systems.
2470
2471
2472 $kpsewhich ["kpsewhich %S"]
2473 The program called to locate a source file when the name alone
2474 is not sufficient. Most filenames used by latexmk have suffi‐
2475 cient path information to be found directly. But sometimes,
2476 notably when a .bib or a .bst file is found from the log file of
2477 a bibtex or biber run, only the base name of the file is known,
2478 but not its path. The program specified by $kpsewhich is used to
2479 find it.
2480
2481 (For advanced users: Because of the different way in which
2482 latexmk uses the command specified in $kpsewhich, some of the
2483 possibilities listed in the FORMAT OF COMMAND SPECIFICATIONS do
2484 not apply. The internal and start keywords are not available. A
2485 simple command specification with possible options and then "%S"
2486 is all that is guaranteed to work. Note that for other com‐
2487 mands, "%S" is substituted by a single source file. In contrast,
2488 for $kpsewhich, "%S" may be substituted by a long list of space-
2489 separated filenames, each of which is quoted. The result on
2490 STDOUT of running the command is then piped to latexmk.)
2491
2492 See also the @BIBINPUTS variable for another way that latexmk
2493 also uses to try to locate files; it applies only in the case of
2494 .bib files.
2495
2496 $kpsewhich_show [0]
2497 Whether to show diagnostics about invocations of kpsewhich: the
2498 command line use to invoke it and the results. These diagnos‐
2499 tics are shown if $kpsewhich_show is non-zero or if diagnostics
2500 mode is on. (But in the second case, lots of other diagnostics
2501 are also shown.) Without these diagnostics there is nothing
2502 visible in latexmk's screen output about invocations of kpse‐
2503 which.
2504
2505 $landscape_mode [0]
2506 If nonzero, run in landscape mode, using the landscape mode pre‐
2507 viewers and dvi to postscript converters. Equivalent to the -l
2508 option. Normally not needed with current previewers.
2509
2510 $latex ["latex %O %S"]
2511 Specifies the command line for the LaTeX processing program.
2512 Note that as with other programs, you can use this variable not
2513 just to change the name of the program used, but also specify
2514 options to the program. E.g.,
2515
2516 $latex = "latex --src-specials %O %S";
2517
2518 To do a coordinated setting of all of $latex, $pdflatex, $luala‐
2519 tex, and $xelatex, see the section "Advanced Configuration".
2520
2521
2522 %latex_input_extensions
2523 This variable specifies the extensions tried by latexmk when it
2524 finds that a LaTeX run resulted in an error that a file has not
2525 been found, and the file is given without an extension. This
2526 typically happens when LaTeX commands of the form \input{file}
2527 or \includegraphics{figure}, when the relevant source file does
2528 not exist.
2529
2530 In this situation, latexmk searches for custom dependencies to
2531 make the missing file(s), but restricts it to the extensions
2532 specified by the variable %latex_input_extensions. The default
2533 extensions are 'tex' and 'eps'.
2534
2535 (For Perl experts: %latex_input_extensions is a hash whose keys
2536 are the extensions. The values are irrelevant.) Two subrou‐
2537 tines are provided for manipulating this and the related vari‐
2538 able %pdflatex_input_extensions, add_input_ext and
2539 remove_input_ext. They are used as in the following examples
2540 are possible lines in an initialization file:
2541
2542 remove_input_ext( 'latex', 'tex' );
2543
2544 removes the extension 'tex' from latex_input_extensions
2545
2546 add_input_ext( 'latex', 'asdf' );
2547
2548 add the extension 'asdf to latex_input_extensions. (Naturally
2549 with such an extension, you should have made an appropriate cus‐
2550 tom dependency for latexmk, and should also have done the appro‐
2551 priate programming in the LaTeX source file to enable the file
2552 to be read. The standard extensions are handled by LaTeX and
2553 its graphics/graphicx packages.)
2554
2555 $latex_silent_switch ["-interaction=batchmode"]
2556 Switch(es) for the LaTeX processing program when silent mode is
2557 on.
2558
2559 If you use MikTeX, you may prefer the results if you configure
2560 the options to include -c-style-errors, e.g., by the following
2561 line in an initialization file
2562
2563 $latex_silent_switch = "-interaction=batchmode -c-style-
2564 errors";
2565
2566
2567 $lpr ["lpr %O %S" under UNIX/Linux, "NONE lpr" under MS-Windows]
2568 The command to print postscript files.
2569
2570 Under MS-Windows (unlike UNIX/Linux), there is no standard pro‐
2571 gram for printing files. But there are ways you can do it. For
2572 example, if you have gsview installed, you could use it with the
2573 option "/p":
2574
2575 $lpr = '"c:/Program Files/Ghostgum/gsview/gsview32.exe" /p';
2576
2577 If gsview is installed in a different directory, you will need
2578 to make the appropriate change. Note the combination of single
2579 and double quotes around the name. The single quotes specify
2580 that this is a string to be assigned to the configuration vari‐
2581 able $lpr. The double quotes are part of the string passed to
2582 the operating system to get the command obeyed; this is neces‐
2583 sary because one part of the command name ("Program Files") con‐
2584 tains a space which would otherwise be misinterpreted.
2585
2586 $lpr_dvi ["NONE lpr_dvi"]
2587 The printing program to print dvi files.
2588
2589 $lpr_pdf ["NONE lpr_pdf"]
2590 The printing program to print pdf files.
2591
2592 Under MS-Windows you could set this to use gsview, if it is
2593 installed, e.g.,
2594
2595 $lpr = '"c:/Program Files/Ghostgum/gsview/gsview32.exe" /p';
2596
2597 If gsview is installed in a different directory, you will need
2598 to make the appropriate change. Note the double quotes around
2599 the name: this is necessary because one part of the command name
2600 ("Program Files") contains a space which would otherwise be mis‐
2601 interpreted.
2602
2603 $lualatex ["lualatex %O %S"]
2604 Specifies the command line for the LaTeX processing program that
2605 is to be used when the lualatex program is called for (e.g., by
2606 the option -lualatex.
2607
2608 To do a coordinated setting of all of $latex, $pdflatex, $luala‐
2609 tex, and $xelatex, see the section "Advanced Configuration".
2610
2611
2612 %lualatex_input_extensions
2613 This variable specifies the extensions tried by latexmk when it
2614 finds that a lualatex run resulted in an error that a file has
2615 not been found, and the file is given without an extension.
2616 This typically happens when LaTeX commands of the form
2617 \input{file} or \includegraphics{figure}, when the relevant
2618 source file does not exist.
2619
2620 In this situation, latexmk searches for custom dependencies to
2621 make the missing file(s), but restricts it to the extensions
2622 specified by the variable %pdflatex_input_extensions. The
2623 default extensions are 'tex', 'pdf', 'jpg, and 'png'.
2624
2625 See details of the %latex_input_extensions for other information
2626 that equally applies to %lualatex_input_extensions.
2627
2628 $lualatex_silent_switch ["-interaction=batchmode"]
2629 Switch(es) for the lualatex program (specified in the variable
2630 $lualatex) when silent mode is on.
2631
2632 See details of the $latex_silent_switch for other information
2633 that equally applies to $lualatex_silent_switch.
2634
2635 $make ["make"]
2636 The make processing program.
2637
2638 $makeindex ["makeindex %O -o %D %S"]
2639 The index processing program.
2640
2641 $makeindex_silent_switch ["-q"]
2642 Switch(es) for the index processing program when silent mode is
2643 on.
2644
2645 $max_repeat [5]
2646 The maximum number of times latexmk will run latex/pdflatex
2647 before deciding that there may be an infinite loop and that it
2648 needs to bail out, rather than rerunning latex/pdflatex again to
2649 resolve cross-references, etc. The default value covers all
2650 normal cases.
2651
2652 (Note that the "etc" covers a lot of cases where one run of
2653 latex/pdflatex generates files to be read in on a later run.)
2654
2655 $MSWin_back_slash [1]
2656 This configuration variable only has an effect when latexmk is
2657 running under MS-Windows. With the default value of 1 for this
2658 variable, when a command is executed under MS-Windows, latexmk
2659 substitutes "\" for the separator character between components
2660 of a directory name. Internally, latexmk uses "/" for the
2661 directory separator character, which is the character used by
2662 Unix-like systems.
2663
2664 For almost all programs and for almost all filenames under MS-
2665 Windows, both "\" and "/" are acceptable as the directory sepa‐
2666 rator character, provided at least that filenames are properly
2667 quoted. But it is possible that programs exist that only accept
2668 "\" on the command line, since that is the standard directory
2669 separator for MS-Windows. So for safety latexmk makes the sub‐
2670 stitution from "/" to "\", by default.
2671
2672 However there are also programs on MS-Windows for which a back
2673 slash "\" is interpreted differently than as a directory separa‐
2674 tor; for these the directory separator should be "/". Programs
2675 with this behavior include all the *latex programs in the
2676 TeXLive implementation (but not the MiKTeX implementation).
2677 Hence if you use TeXLive on MS-Windows, then $MSWin_back_slash
2678 should be set to zero.
2679
2680
2681 $new_viewer_always [0]
2682 This variable applies to latexmk only in continuous-preview
2683 mode. If $new_viewer_always is 0, latexmk will check for a pre‐
2684 viously running previewer on the same file, and if one is run‐
2685 ning will not start a new one. If $new_viewer_always is non-
2686 zero, this check will be skipped, and latexmk will behave as if
2687 no viewer is running.
2688
2689 $out_dir [""]
2690 If non-blank, this variable specifies the directory in which
2691 output files are to be written by a run of (pdf)latex. See also
2692 the variable $aux_dir.
2693
2694 The effect of this variable (when non-blank) is achieved by
2695 using the -output-directory option of (pdf)latex. This exists
2696 in the usual current (Dec. 2011 and later) implementations of
2697 TeX, i.e., MiKTeX and TeXLive. But it may not be present in
2698 other versions.
2699
2700 If you also use the -cd option, and $out_dir (or $aux_dir) con‐
2701 tains a relative path, then the path is interpreted relative to
2702 the document directory.
2703
2704 Commonly, the directory specified for output files is a subdi‐
2705 rectory of the current working directory. However, if you spec‐
2706 ify some other directory, e.g., "/tmp/foo" or "../output", be
2707 aware that this could cause problems, e.g., with makeindex or
2708 bibtex. This is because modern versions of these programs, by
2709 default, will refuse to work when they find that they are asked
2710 to write to a file in a directory that appears not to be the
2711 current working directory or one of its subdirectories. This is
2712 part of security measures by the whole TeX system that try to
2713 prevent malicious or errant TeX documents from incorrectly mess‐
2714 ing with a user's files. If for $out_dir or $aux_dir you really
2715 do need to specify an absolute pathname (e.g., "/tmp/foo") or a
2716 path (e.g., "../output") that includes a higher-level directory,
2717 and you need to use makeindex or bibtex, then you need to dis‐
2718 able the security measures (and assume any risks). One way of
2719 doing this is to temporarily set an operating system environment
2720 variable openout_any to "a" (as in "all"), to override the
2721 default "paranoid" setting.
2722
2723 $pdf_mode [0]
2724 If zero, do NOT generate a pdf version of the document. If
2725 equal to 1, generate a pdf version of the document using pdfla‐
2726 tex, using the command specified by the $pdflatex variable. If
2727 equal to 2, generate a pdf version of the document from the ps
2728 file, by using the command specified by the $ps2pdf variable.
2729 If equal to 3, generate a pdf version of the document from the
2730 dvi file, by using the command specified by the $dvipdf vari‐
2731 able. If equal to 4, generate a pdf version of the document
2732 using lualatex, using the command specified by the $lualatex
2733 variable. If equal to 5, generate a pdf version (and an xdv
2734 version) of the document using xelatex, using the commands spec‐
2735 ified by the $xelatex and xdvipdfmx variables.
2736
2737 In $pdf_mode=2, it is ensured that .dvi and .ps files are also
2738 made. In $pdf_mode=3, it is ensured that a .dvi file is also
2739 made. But this may be overridden by the document.
2740
2741 $pdflatex ["pdflatex %O %S"]
2742 Specifies the command line for the LaTeX processing program in a
2743 version that makes a pdf file instead of a dvi file.
2744
2745 An example use of this variable is to add certain options to the
2746 command line for the program, e.g.,
2747
2748 $pdflatex = "pdflatex --shell-escape %O %S";
2749
2750 (In some earlier versions of latexmk, you needed to use an
2751 assignment to $pdflatex to allow the use of lualatex or xelatex
2752 instead of pdflatex. There are now separate configuration vari‐
2753 ables for the use of lualatex or xelatex. See $lualatex and
2754 $xelatex.)
2755
2756 To do a coordinated setting of all of $latex, $pdflatex, $luala‐
2757 tex, and $xelatex, see the section "Advanced Configuration".
2758
2759 %pdflatex_input_extensions
2760 This variable specifies the extensions tried by latexmk when it
2761 finds that a pdflatex run resulted in an error that a file has
2762 not been found, and the file is given without an extension.
2763 This typically happens when LaTeX commands of the form
2764 \input{file} or \includegraphics{figure}, when the relevant
2765 source file does not exist.
2766
2767 In this situation, latexmk searches for custom dependencies to
2768 make the missing file(s), but restricts it to the extensions
2769 specified by the variable %pdflatex_input_extensions. The
2770 default extensions are 'tex', 'pdf', 'jpg, and 'png'.
2771
2772 See details of the %latex_input_extensions for other information
2773 that equally applies to %pdflatex_input_extensions.
2774
2775 $pdflatex_silent_switch ["-interaction=batchmode"]
2776 Switch(es) for the pdflatex program (specified in the variable
2777 $pdflatex) when silent mode is on.
2778
2779 See details of the $latex_silent_switch for other information
2780 that equally applies to $pdflatex_silent_switch.
2781
2782 $pdf_previewer ["start acroread %O %S"]
2783 The command to invoke a pdf-previewer.
2784
2785 On MS-Windows, the default is changed to "cmd /c start """;
2786 under more recent versions of Windows, this will cause to be run
2787 whatever command the system has associated with .pdf files. But
2788 this may be undesirable if this association is to acroread --
2789 see the notes in the explanation of the -pvc option.]
2790
2791 On OS-X the default is changed to "open %S", which results in
2792 OS-X starting up (and detaching) the viewer associated with the
2793 file. By default, for pdf files this association is to OS-X's
2794 preview, which is quite satisfactory.
2795
2796 WARNING: Problem under MS-Windows: if acroread is used as the
2797 pdf previewer, and it is actually viewing a pdf file, the pdf
2798 file cannot be updated. Thus makes acroread a bad choice of
2799 previewer if you use latexmk's previous-continuous mode (option
2800 -pvc) under MS-windows. This problem does not occur if, for
2801 example, SumatraPDF or gsview is used to view pdf files.
2802
2803 Important note: Normally you will want to have a previewer run
2804 detached, so that latexmk doesn't wait for the previewer to ter‐
2805 minate before continuing its work. So normally you should pre‐
2806 fix the command by "start ", which flags to latexmk that it
2807 should do the detaching of the previewer itself (by whatever
2808 method is appropriate to the operating system). But sometimes
2809 letting latexmk do the detaching is not appropriate (for a vari‐
2810 ety of non-trivial reasons), so you should put the "start " bit
2811 in yourself, whenever it is needed.
2812
2813 $pdf_update_command [""]
2814 When the pdf previewer is set to be updated by running a com‐
2815 mand, this is the command that is run. See the information for
2816 the variable $pdf_update_method.
2817
2818 $pdf_update_method [1 under UNIX, 3 under MS-Windows]
2819 How the pdf viewer updates its display when the pdf file has
2820 changed. See the information on the variable $dvi_update_method
2821 for the codes. (Note that information needs be changed slightly
2822 so that for the value 4, to run a command to do the update, the
2823 command is specified by the variable $pdf_update_command, and
2824 for the value 2, to specify update by signal, the signal is
2825 specified by $pdf_update_signal.)
2826
2827 Note that acroread under MS-Windows (but not UNIX) locks the pdf
2828 file, so the default value is then 3.
2829
2830 Arranging to use a command to get a previewer explicitly updated
2831 requires three variables to be set. For example:
2832
2833 $pdf_previewer = "start xpdf -remote %R %O %S";
2834 $pdf_update_method = 4;
2835 $pdf_update_command = "xpdf -remote %R -reload";
2836
2837 The first setting arranges for the xpdf program to be used in
2838 its "remote server mode", with the server name specified as the
2839 rootname of the TeX file. The second setting arranges for
2840 updating to be done in response to a command, and the third set‐
2841 ting sets the update command.
2842
2843 $pdf_update_signal [Under UNIX: SIGHUP, which is a system-dependent
2844 value]
2845 The number of the signal that is sent to the pdf viewer when it
2846 is updated by sending a signal -- see the information on the
2847 variable $pdf_update_method. The default value is the one
2848 appropriate for gv on a UNIX system.
2849
2850 $pid_position[1 under UNIX, -1 under MS-Windows]
2851 The variable $pid_position is used to specify which word in
2852 lines of the output from $pscmd corresponds to the process ID.
2853 The first word in the line is numbered 0. The default value of
2854 1 (2nd word in line) is correct for Solaris 2.6, Linux, and OS-X
2855 with their default settings of $pscmd.
2856
2857 Setting the variable to -1 is used to indicate that $pscmd is
2858 not to be used.
2859
2860 $postscript_mode [0]
2861 If nonzero, generate a postscript version of the document.
2862 Equivalent to the -ps option.
2863
2864 If some other request is made for which a postscript file is
2865 needed, then $postscript_mode will be set to 1.
2866
2867 $pre_tex_code ['']
2868
2869 Sets TeX code to be executed before inputting the source file.
2870 This works if the relevant one of $latex, etc contains a suit‐
2871 able command line with a %P or %U substitution. For example you
2872 could do
2873
2874 $latex = 'latex %O %P';
2875 $pre_tex_code = '\AtBeginDocument{An initial message\par}';
2876
2877 To set all of $latex, $pdflatex, $lualatex, and $xelatex you
2878 could use the subroutine alt_tex_cmds:
2879
2880 &alt_tex_cmds;
2881 $pre_tex_code = '\AtBeginDocument{An initial message\par}';
2882
2883
2884
2885 $preview_continuous_mode [0]
2886 If nonzero, run a previewer to view the document, and continue
2887 running latexmk to keep .dvi up-to-date. Equivalent to the -pvc
2888 option. Which previewer is run depends on the other settings,
2889 see the command line options -view=, and the variable $view.
2890
2891 $preview_mode [0]
2892 If nonzero, run a previewer to preview the document. Equivalent
2893 to the -pv option. Which previewer is run depends on the other
2894 settings, see the command line options -view=, and the variable
2895 $view.
2896
2897 $printout_mode [0]
2898 If nonzero, print the document using the command specified in
2899 the $lpr variable. Equivalent to the -p option. This is recom‐
2900 mended not to be set from an RC file, otherwise you could waste
2901 lots of paper.
2902
2903 $print_type = ["auto"]
2904 Type of file to printout: possibilities are "auto", "dvi",
2905 "none", "pdf", or "ps". See the option -print= for the meaning
2906 of the "auto" value.
2907
2908 $pscmd Command used to get all the processes currently run by the user.
2909 The -pvc option uses the command specified by the variable
2910 $pscmd to determine if there is an already running previewer,
2911 and to find the process ID (needed if latexmk needs to signal
2912 the previewer about file changes).
2913
2914 Each line of the output of this command is assumed to correspond
2915 to one process. See the $pid_position variable for how the
2916 process number is determined.
2917
2918 The default for pscmd is "NONE" under MS-Windows and cygwin
2919 (i.e., the command is not used), "ps -ww -u $ENV{USER}" under
2920 OS-X, and "ps -f -u $ENV{USER}" under other operating systems
2921 (including Linux). In these specifications "$ENV{USER}" is sub‐
2922 stituted by the username.
2923
2924 $ps2pdf ["ps2pdf %O %S %D"]
2925 Command to convert .ps to .pdf file.
2926
2927 $ps_filter [empty]
2928 The postscript file filter to be run on the newly produced post‐
2929 script file before other processing. Equivalent to specifying
2930 the -pF option.
2931
2932 $ps_previewer ["start gv %O %S", but start %O %S under MS-Windows]
2933 The command to invoke a ps-previewer. (The default under MS-
2934 Windows will cause to be run whatever command the system has
2935 associated with .ps files.)
2936
2937 Note that gv could be used with the -watch option updates its
2938 display whenever the postscript file changes, whereas ghostview
2939 does not. However, different versions of gv have slightly dif‐
2940 ferent ways of writing this option. You can configure this
2941 variable appropriately.
2942
2943 WARNING: Linux systems may have installed one (or more) versions
2944 of gv under different names, e.g., ggv, kghostview, etc, but
2945 perhaps not one actually called gv.
2946
2947 Important note: Normally you will want to have a previewer run
2948 detached, so that latexmk doesn't wait for the previewer to ter‐
2949 minate before continuing its work. So normally you should pre‐
2950 fix the command by "start ", which flags to latexmk that it
2951 should do the detaching of the previewer itself (by whatever
2952 method is appropriate to the operating system). But sometimes
2953 letting latexmk do the detaching is not appropriate (for a vari‐
2954 ety of non-trivial reasons), so you should put the "start " bit
2955 in yourself, whenever it is needed.
2956
2957
2958 $ps_previewer_landscape ["start gv -swap %O %S", but start %O %S under
2959 MS-Windows]
2960 The command to invoke a ps-previewer in landscape mode.
2961
2962 $ps_update_command [""]
2963 When the postscript previewer is set to be updated by running a
2964 command, this is the command that is run. See the information
2965 for the variable $ps_update_method.
2966
2967 $ps_update_method [0 under UNIX, 1 under MS-Windows]
2968 How the postscript viewer updates its display when the .ps file
2969 has changed. See the information on the variable
2970 $dvi_update_method for the codes. (Note that information needs
2971 be changed slightly so that for the value 4, to run a command to
2972 do the update, the command is specified by the variable
2973 $ps_update_command, and for the value 2, to specify update by
2974 signal, the signal is specified by $ps_update_signal.)
2975
2976 $ps_update_signal [Under UNIX: SIGHUP, which is a system-dependent
2977 value]
2978 The number of the signal that is sent to the pdf viewer when it
2979 is updated by sending a signal -- see $ps_update_method. The
2980 default value is the one appropriate for gv on a UNIX system.
2981
2982 $pvc_timeout [0]
2983 If this variable is nonzero, there will be a timeout in pvc
2984 mode after a period of inactivity. Inactivity means a period
2985 when latexmk has detected no file changes and hence has not
2986 taken any actions like compiling the document. The period of
2987 inactivity is in the variable $pvc_timeout_mins.
2988
2989
2990 $pvc_timeout_mins [30]
2991 The period of inactivity, in minutes, after which pvc mode times
2992 out. This is used if $pvc_timeout is nonzero.
2993
2994 $pvc_view_file_via_temporary [1]
2995 The same as $always_view_file_via_temporary, except that it only
2996 applies in preview-continuous mode (-pvc option).
2997
2998 $quote_filenames [1]
2999 This specifies whether substitutions for placeholders in command
3000 specifications (as in $pdflatex) are surrounded by double
3001 quotes. If this variable is 1 (or any other value Perl regards
3002 as true), then quoting is done. Otherwise quoting is omitted.
3003
3004 The quoting method used by latexmk is tested to work correctly
3005 under UNIX systems (including Linux and Mac OS-X) and under MS-
3006 Windows. It allows the use of filenames containing special
3007 characters, notably spaces. (But note that many versions of
3008 latex and pdflatex cannot correctly deal with TeX files whose
3009 names contain spaces. Latexmk's quoting only ensures that such
3010 filenames are correctly treated by the operating system in pass‐
3011 ing arguments to programs.)
3012
3013 $recorder [1]
3014 Whether to use the -recorder option to latex and pdflatex. Use
3015 of this option results in a file of extension .fls containing a
3016 list of the files that these programs have read and written.
3017 Latexmk will then use this file to improve its detection of
3018 source files and generated files after a run of latex or pdfla‐
3019 tex.
3020
3021 It is generally recommended to use this option (or to configure
3022 the $recorder variable to be on.) But it only works if
3023 (pdf)latex supports the -recorder option, which is true for most
3024 current implementations
3025
3026 Note about the name of the .fls file: Most implementations of
3027 (pdf)latex produce an .fls file with the same basename as the
3028 main document's LaTeX, e.g., for Document.tex, the .fls file is
3029 Document.fls. However, some implementations instead produce
3030 files named for the program, i.e., latex.fls or pdflatex.fls.
3031 In this second case, latexmk copies the latex.fls or pdfla‐
3032 tex.fls to a file with the basename of the main LaTeX document,
3033 e.g., Document.fls.
3034
3035 $search_path_separator [See below for default]
3036 The character separating paths in the environment variables TEX‐
3037 INPUTS, BIBINPUTS, and BSTINPUTS. This variable is mainly used
3038 by latexmk when the -outdir, -output-directory, -auxdir, and/or
3039 -aux-directory options are used. In that case latexmk needs to
3040 communicate appropriately modified search paths to bibtex,
3041 dvipdf, dvips, and (pdf)latex.
3042
3043 [Comment to technically savvy readers: (pdf)latex doesn't actu‐
3044 ally need the modified search path. But, surprisingly, dvipdf
3045 and dvips do, because sometimes graphics files get generated in
3046 the output or aux directories.]
3047
3048 The default under MSWin and Cygwin is ';' and under UNIX-like
3049 operating systems (including Linux and OS-X) is ':'. Normally
3050 the defaults give correct behavior. But there can be difficul‐
3051 ties if your operating system is of one kind, but some of your
3052 software is running under an emulator for the other kind of
3053 operating system; in that case you'll need to find out what is
3054 needed, and set $search_path_separator explicitly. (The same
3055 goes, of course, for unusual operating systems that are not in
3056 the MSWin, Linux, OS-X, Unix collection.)
3057
3058 $show_time [0]
3059 Whether to show CPU time used.
3060
3061 $silence_logfile_warnings [0]
3062 Whether after a run of (pdf)latex to summarize warnings in the
3063 log file about undefined citations and references. Setting
3064 $silence_logfile_warnings=0 gives the summary of warnings (pro‐
3065 vided silent mode isn't also set), and this is useful to locate
3066 undefined citations and references without searching through the
3067 much more verbose log file or the screen output of (pdf)latex.
3068 But the summary can also be excessively annoying. The default
3069 is not to give these warnings. The command line options
3070 -silence_logfile_warning_list and -silence_logfile_warning_list-
3071 also set this variable.
3072
3073 Note that multiple occurrences for the same undefined object on
3074 the same page and same line will be compressed to a single warn‐
3075 ing.
3076
3077 $silent [0]
3078 Whether to run silently. Setting $silent to 1 has the same
3079 effect as the -quiet of -silent options on the command line.
3080
3081 $sleep_time [2]
3082 The time to sleep (in seconds) between checking for source file
3083 changes when running with the -pvc option. This is subject to a
3084 minimum of one second delay, except that zero delay is also
3085 allowed.
3086
3087 A value of exactly 0 gives no delay, and typically results in
3088 100% CPU usage, which may not be desirable.
3089
3090 $texfile_search [""]
3091 This is an obsolete variable, replaced by the @default_files
3092 variable.
3093
3094 For backward compatibility, if you choose to set $tex‐
3095 file_search, it is a string of space-separated filenames, and
3096 then latexmk replaces @default_files with the filenames in $tex‐
3097 file_search to which is added "*.tex".
3098
3099 $success_cmd [undefined]
3100 See the documentation for $compiling_cmd.
3101
3102 $tmpdir [See below for default]
3103 Directory to store temporary files that latexmk may generate
3104 while running.
3105
3106 The default under MSWindows (including cygwin), is to set
3107 $tmpdir to the value of the first of whichever of the system
3108 environment variables TMPDIR or TEMP exists, otherwise to the
3109 current directory. Under other operating systems (expected to
3110 be UNIX/Linux, including OS-X), the default is the value of the
3111 system environment variable TMPDIR if it exists, otherwise
3112 "/tmp".
3113
3114 $use_make_for_missing_files [0]
3115 Whether to use make to try and make files that are missing after
3116 a run of latex or pdflatex, and for which a custom dependency
3117 has not been found. This is generally useful only when latexmk
3118 is used as part of a bigger project which is built by using the
3119 make program.
3120
3121 Note that once a missing file has been made, no further calls to
3122 make will be made on a subsequent run of latexmk to update the
3123 file. Handling this problem is the job of a suitably defined
3124 Makefile. See the section "USING latexmk WITH make" for how to
3125 do this. The intent of calling make from latexmk is merely to
3126 detect dependencies.
3127
3128 $view ["default"]
3129 Which kind of file is to be previewed if a previewer is used.
3130 The possible values are "default", "dvi", "ps", "pdf". The
3131 value of "default" means that the "highest" of the kinds of file
3132 generated is to be used (among .dvi, .ps and .pdf).
3133
3134
3135 $warnings_as_errors [0]
3136 Normally latexmk copies the behavior of latex in treating unde‐
3137 fined references and citations and multiply defined references
3138 as conditions that give a warning but not an error. The vari‐
3139 able $warnings_as_errors controls whether this behavior is modi‐
3140 fied.
3141
3142 When the variable is non-zero, latexmk at the end of its run
3143 will return a non-zero status code to the operating system if
3144 any of the files processed gives a warning about problems with
3145 citations or references (i.e., undefined citations or references
3146 or multiply defined references). This is after latexmk has com‐
3147 pleted all the runs it needs to try and resolve references and
3148 citations. Thus $warnings_as_errors being nonzero causes
3149 latexmk to treat such warnings as errors, but only when they
3150 occur on the last run of (pdf)latex and only after processing is
3151 complete. A non-zero value $warnings_as_errors can be set by
3152 the command-line option -Werror.
3153
3154 The default behavior is normally satisfactory in the usual edit-
3155 compile-edit cycle. But, for example, latexmk can also be used
3156 as part of a build process for some bigger project, e.g., for
3157 creating documentation in the build of a software application.
3158 Then it is often sensible to treat citation and reference warn‐
3159 ings as errors that require the overall build process to be
3160 aborted. Of course, since multiple runs of (pdf)latex are gen‐
3161 erally needed to resolve references and citations, what matters
3162 is not the warnings on the first run, but the warnings on the
3163 last run; latexmk takes this into account appropriately.
3164
3165 In addition, when preview-continuous mode is used, a non-zero
3166 value for $warnings_as_errors changes the use of the commands
3167 $failure_cmd, $warning_cmd, and $success_cmd after a complia‐
3168 tion. If there are citation or reference warnings, but no other
3169 errors, the behavior is as follows. If $warning_cmd is set, it
3170 is used. If it is not set, then then if $warnings_as_errors is
3171 non-zero and $failure_cmd is set, then $failure_cmd. Otherwise
3172 $success_cmd is used, if it is set. (The foregoing explanation
3173 is rather complicated, because latexmk has to deal with the case
3174 that one or more of the commands isn't set.)
3175
3176
3177 $xdvipdfmx ["xdvipdfmx -E -o %D %O %S"]
3178
3179 The program to make a pdf file from an xdv file (used in con‐
3180 junction with xelatex when $pdf_mode=5).
3181
3182 $xdvipdfmx_silent_switch ["-q"]
3183 Switch(es) for the xdvipdfmx program when silent mode is on.
3184
3185 $xelatex ["xelatex %O %S"]
3186 Specifies the command line for the LaTeX processing program of
3187 when the xelatex program is called for. See the documentation
3188 of the -xelatex option for some special properties of latexmk's
3189 use of xelatex.
3190
3191 Note about xelatex: latexmk uses xelatex to make an .xdv rather
3192 than .pdf file, with the .pdf file being created in a separate
3193 step. This is enforced by the use of the -no-pdf option. If %O
3194 is part of the command for invoking xelatex, then latexmk will
3195 insert the -no-pdf option automatically, otherwise you must pro‐
3196 vide the option yourself. See the documentation for the -pdfxe
3197 option for why latexmk makes a .xdv file rather than a .pdf file
3198 when xelatex is used.
3199
3200 To do a coordinated setting of all of $latex, $pdflatex, $luala‐
3201 tex, and $xelatex, see the section "Advanced Configuration".
3202
3203
3204 %xelatex_input_extensions
3205 This variable specifies the extensions tried by latexmk when it
3206 finds that an xelatex run resulted in an error that a file has
3207 not been found, and the file is given without an extension.
3208 This typically happens when LaTeX commands of the form
3209 \input{file} or \includegraphics{figure}, when the relevant
3210 source file does not exist.
3211
3212 In this situation, latexmk searches for custom dependencies to
3213 make the missing file(s), but restricts it to the extensions
3214 specified by the variable %xelatex_input_extensions. The
3215 default extensions are 'tex', 'pdf', 'jpg, and 'png'.
3216
3217 See details of the %latex_input_extensions for other information
3218 that equally applies to %xelatex_input_extensions.
3219
3220 $xelatex_silent_switch ["-interaction=batchmode"]
3221 Switch(es) for the xelatex program (specified in the variable
3222 $xelatex) when silent mode is on.
3223
3224 See details of the $latex_silent_switch for other information
3225 that equally applies to $xelatex_silent_switch.
3226
3227
3228
3229
3231 In any RC file a set of custom dependencies can be set up to convert a
3232 file with one extension to a file with another. An example use of this
3233 would be to allow latexmk to convert a .fig file to .eps to be included
3234 in the .tex file.
3235
3236
3237 Defining a custom dependency:
3238 The old method of configuring latexmk to use a custom dependency was to
3239 directly manipulate the @cus_dep_list array that contains information
3240 defining the custom dependencies. (See the section "Old Method of
3241 Defining Custom Dependencies" for details.) This method still works,
3242 but is no longer preferred.
3243
3244 A better method is to use the subroutines that allow convenient manipu‐
3245 lations of the custom dependency list. These are
3246
3247 add_cus_dep( fromextension, toextension, must, subroutine )
3248 remove_cus_dep( fromextension, toextension )
3249 show_cus_dep()
3250
3251 The arguments are as follows:
3252
3253 from extension:
3254 The extension of the file we are converting from (e.g. "fig").
3255 It is specified without a period.
3256
3257 to extension:
3258 The extension of the file we are converting to (e.g. "eps"). It
3259 is specified without a period.
3260
3261 must: If non-zero, the file from which we are converting must exist,
3262 if it doesn't exist latexmk will give an error message and exit
3263 unless the -f option is specified. If must is zero and the file
3264 we are converting from doesn't exist, then no action is taken.
3265 Generally, the appropriate value of must is zero.
3266
3267 function:
3268 The name of the subroutine that latexmk should call to perform
3269 the file conversion. The first argument to the subroutine is
3270 the base name of the file to be converted without any extension.
3271 The subroutines are declared in the syntax of Perl. The func‐
3272 tion should return 0 if it was successful and a nonzero number
3273 if it failed.
3274
3275
3276 Naturally add_cus_dep adds a custom dependency with the specified from
3277 and to extensions. If a custom dependency has been previously defined
3278 (e.g., in an rcfile that was read earlier), then it is replaced by the
3279 new one.
3280
3281 The subroutine remove_cus_dep removes the specified custom dependency.
3282 The subroutine show_cus_dep causes a list of the currently defined cus‐
3283 tom dependencies to be sent to the screen output.
3284
3285
3286 How custom dependencies are used:
3287 An instance of a custom dependency rule is created whenever latexmk
3288 detects that a run of latex/pdflatex needs to read a file, like a
3289 graphics file, whose extension is the to-extension of a custom depen‐
3290 dency. Then latexmk examines whether a file exists with the same name,
3291 but with the corresponding from-extension, as specified in the custom-
3292 dependency. If it does, then a corresponding instance of the custom
3293 dependency is created, after which the rule is invoked whenever the
3294 destination file (the one with the to-extension) is out-of-date with
3295 respect to the corresponding source file.
3296
3297 To make the new destination file, the Perl subroutine specified in the
3298 rule is invoked, with an argument that is the base name of the files in
3299 question. Simple cases just involve a subroutine invoking an external
3300 program; this can be done by following the templates below, even by
3301 those without knowledge of the Perl programming language. Of course,
3302 experts could do something much more elaborate.
3303
3304 One item in the specification of each custom-dependency rule, labeled
3305 "must" above, specifies how the rule should be applied when the source
3306 file fails to exist.
3307
3308 When latex reports that an input file (e.g., a graphics file) does not
3309 exist, latexmk tries to find a source file and a custom dependency that
3310 can be used to make it. If it succeeds, then it creates an instance of
3311 the custom dependency and invokes it to make the missing file, after
3312 which the next pass of latex etc will be able to read the newly created
3313 file.
3314
3315 Note for advanced usage: The operating system's environment variable
3316 TEXINPUTS can be used to specify a search path for finding files by
3317 latex etc. Correspondingly, when a missing file is reported, latexmk
3318 looks in the directories specified in TEXINPUTS as well as in the cur‐
3319 rent directory, to find a source file from which an instance of a cus‐
3320 tom dependency can be used to make the missing file.
3321
3322
3323 Function to implement custom dependency, traditional method:
3324 The function that implements a custom dependency gets the information
3325 on the files to be processed in two ways. The first is through its one
3326 argument; the argument contains the base name of the source and desti‐
3327 nation files. The second way is described later.
3328
3329 A simple and typical example of code in an initialization rcfile using
3330 the first method is:
3331
3332 add_cus_dep( 'fig', 'eps', 0, 'fig2eps' );
3333 sub fig2eps {
3334 system( "fig2dev -Leps \"$_[0].fig\" \"$_[0].eps\"" );
3335 }
3336
3337 The first line adds a custom dependency that converts a file with
3338 extension "fig", as created by the xfig program, to an encapsulated
3339 postscript file, with extension "eps". The remaining lines define a
3340 subroutine that carries out the conversion. If a rule for converting
3341 "fig" to "eps" files already exists (e.g., from a previously read-in
3342 initialization file), the latexmk will delete this rule before making
3343 the new one.
3344
3345 Suppose latexmk is using this rule to convert a file "figure.fig" to
3346 "figure.eps". Then it will invoke the fig2eps subroutine defined in
3347 the above code with a single argument "figure", which is the basename
3348 of each of the files (possibly with a path component). This argument
3349 is referred to by Perl as $_[0]. In the example above, the subroutine
3350 uses the Perl command system to invoke the program fig2dev. The double
3351 quotes around the string are a Perl idiom that signify that each string
3352 of the form of a variable name, $_[0] in this case, is to be substi‐
3353 tuted by its value.
3354
3355 If the return value of the subroutine is non-zero, then latexmk will
3356 assume an error occurred during the execution of the subroutine. In
3357 the above example, no explicit return value is given, and instead the
3358 return value is the value returned by the last (and only) statement,
3359 i.e., the invocation of system, which returns the value 0 on success.
3360
3361 If you use pdflatex instead of latex, then you will probably prefer to
3362 convert your graphics files to pdf format, in which case you would
3363 replace the above code in an initialization file by
3364
3365 add_cus_dep( 'fig', 'pdf, 0, 'fig2pdf' );
3366 sub fig2pdf {
3367 system( "fig2dev -Lpdf \"$_[0].fig\" \"$_[0].pdf\"" );
3368 }
3369
3370 Note 1: In the command lines given in the system commands in the above
3371 examples, double quotes have been inserted around the file names
3372 (implemented by '\"' in the Perl language). They immunize the running
3373 of the program against special characters in filenames. Very often
3374 these quotes are not necessary, i.e., they can be omitted. But it is
3375 normally safer to keep them in. Even though the rules for quoting vary
3376 between operating systems, command shells and individual pieces of
3377 software, the quotes in the above examples do not cause problems in the
3378 cases I have tested.
3379
3380 Note 2: One case in which the quotes are important is when the files
3381 are in a subdirectory and your operating system is Microsoft Windows.
3382 Then the separator character for directory components can be either a
3383 forward slash '/' or Microsoft's more usual backward slash ´\'. For‐
3384 ward slashes are generated by latexmk, to maintain its sanity from
3385 software like MiKTeX that mixes both directory separators; but their
3386 correct use normally requires quoted filenames. (See a log file from a
3387 run of MiKTeX (at least in v. 2.9) for an example of the use of both
3388 directory separators.)
3389
3390 Note 3: The subroutines implementing custom dependencies in the exam‐
3391 ples given just have a single line invoking an external program.
3392 That's the usual situation. But since the subroutines are in the Perl
3393 language, you can implement much more complicated processing if you
3394 need it.
3395
3396
3397 Removing custom dependencies, and when you might need to do this:
3398 If you have some general custom dependencies defined in the system or
3399 user initialization file, you may find that for a particular project
3400 they are undesirable. So you might want to delete the unneeded ones.
3401 A situation where this would be desirable is where there are multiple
3402 custom dependencies with the same from-extension or the same to-exten‐
3403 sion. In that case, latexmk might choose a different one from the one
3404 you want for a specific project. As an example, to remove any "fig" to
3405 "eps" rule you would use:
3406
3407 remove_cus_dep( 'fig', 'eps' );
3408
3409 If you have complicated sets of custom dependencies, you may want to
3410 get a listing of the custom dependencies. This is done by using the
3411 line
3412
3413 show_cus_dep();
3414
3415 in an initialization file.
3416
3417
3418 Function implementing custom dependency, alternative methods:
3419 So far the examples for functions to implement custom dependencies have
3420 used the argument of the function to specify the base name of converted
3421 file. This method has been available since very old versions of
3422 latexmk, and many examples can be found, e.g., on the web.
3423
3424 However in later versions of latexmk the internal structure of the
3425 implementation of its "rules" for the steps of processing, including
3426 custom dependencies, became much more powerful. The function imple‐
3427 menting a custom dependency is executed within a special context where
3428 a number of extra variables and subroutines are defined. Publicly doc‐
3429 umented ones, intended to be long-term stable, are listed below, under
3430 the heading "Variables and subroutines for processing a rule".
3431
3432 Examples of their use is given in the following examples, concerning
3433 multiple index files and glossaries.
3434
3435 The only index-file conversion built-in to latexmk is from an ".idx"
3436 file written on one run of latex/pdflatex to an ".ind" file to be read
3437 in on a subsequent run. But with the index.sty package, for example,
3438 you can create extra indexes with extensions that you configure.
3439 Latexmk does not know how to deduce the extensions from the information
3440 it has. But you can easily write a custom dependency. For example if
3441 your latex file uses the command "\newindex{special}{ndx}{nnd}{Special
3442 index}" you will need to get latexmk to convert files with the exten‐
3443 sion .ndx to .nnd. The most elementary method is to define a custom
3444 dependency as follows:
3445
3446 add_cus_dep( 'ndx', 'nnd', 0, 'ndx2nnd' );
3447 sub ndx2nnd {
3448 return system( "makeindex -o \"$_[0].nnd\" \"$_[0].ndx\"" );
3449 }
3450 push @generated_exts, 'ndx', 'nnd';
3451
3452 Notice the added line compared with earlier examples. The extra line
3453 gets the extensions "ndx" and "nnd" added to the list of extensions for
3454 generated files; then the extra index files will be deleted by clean-up
3455 operations
3456
3457 But if you have yet more indexes with yet different extensions, e.g.,
3458 "adx" and "and", then you will need a separate function for each pair
3459 of extensions. This is quite annoying. You can use the Run_subst
3460 function to simplify the definitions to use a single function:
3461
3462 add_cus_dep( 'ndx', 'nnd', 0, 'dx2nd' );
3463 add_cus_dep( 'adx', 'and', 0, 'dx2nd' );
3464 sub dx2nd {
3465 return Run_subst( "makeindex -o %D %S" );
3466 }
3467 push @generated_exts, 'ndx', 'nnd', 'adx', 'and';
3468
3469 You could also instead use
3470
3471 add_cus_dep( 'ndx', 'nnd', 0, 'dx2nd' );
3472 add_cus_dep( 'adx', 'and', 0, 'dx2nd' );
3473 sub dx2nd {
3474 return Run_subst( $makeindex );
3475 }
3476 push @generated_exts, 'ndx', 'nnd', 'adx', 'and';
3477
3478 This last example uses the command specification in $makeindex, and so
3479 any customization you have made for the standard index also applies to
3480 your extra indexes.
3481
3482 Similar techniques can be applied for glossaries.
3483
3484 Those of you with experience with Makefiles, may get concerned that the
3485 .ndx file is written during a run of latex/pdflatex and is always later
3486 than the .nnd last read in. Thus the .nnd appears to be perpetually
3487 out-of-date. This situation, of circular dependencies, is endemic to
3488 latex, and is one of the issues that latexmk is programmed to overcome.
3489 It examines the contents of the files (by use of a checksum), and only
3490 does a remake when the file contents have actually changed.
3491
3492 Of course if you choose to write random data to the .nnd (or the .aux
3493 file, etc) that changes on each new run, then you will have a problem.
3494 For real experts: See the %hash_cal_ignore_pattern if you have to deal
3495 with such problems.
3496
3497
3498 Old Method of Defining Custom Dependencies:
3499 In much older versions of latexmk, the only method of defining custom
3500 dependencies was to directly manipulate the table of custom dependen‐
3501 cies. This is contained in the @cus_dep_list array. It is an array of
3502 strings, and each string in the array has four items in it, each sepa‐
3503 rated by a space, the from-extension, the to-extension, the "must"
3504 item, and the name of the subroutine for the custom dependency. These
3505 were all defined above.
3506
3507 An example of the old method of defining custom dependencies is as fol‐
3508 lows. It is the code in an RC file to ensure automatic conversion of
3509 .fig files to .eps files:
3510
3511 push @cus_dep_list, "fig eps 0 fig2eps";
3512 sub fig2eps {
3513 return system( "fig2dev -Lps \"$_[0].fig\" \"$_[0].eps\"" );
3514 }
3515
3516 This method still works, and is almost equivalent to the code given
3517 earlier that used the add_cus_dep subroutine. However, the old method
3518 doesn't delete any previous custom-dependency for the same conversion.
3519 So the new method is preferable.
3520
3521

3524 For most purposes, simple configuration for latexmk along the lines of
3525 the examples given is sufficient. But sometimes you need something
3526 harder. In this section, I indicate some extra possibilities. Gener‐
3527 ally to use these, you need to be fluent in the Perl language, since
3528 this is what is used in the rc files.
3529
3530 See also the section DEALING WITH ERRORS, PROBLEMS, ETC. See also the
3531 examples in the directory example_rcfiles in the latexmk distributions.
3532 Even if none of the examples apply to your case, they may give you use‐
3533 ful ideas

3536 Utility subroutines
3537 ensure_path( var, values ...)
3538
3539 The first parameter is the name of one of the system's environ‐
3540 ment variables for search paths. The remaining parameters are
3541 values that should be in the variable. For each of the value
3542 parameters, if it isn't already in the variable, then it is
3543 prepended to the variable; in that case the environment variable
3544 is created if it doesn't already exist. For separating values,
3545 the character appropriate the the operating system is used --
3546 see the configuration variable $search_path_separator.
3547
3548 Example:
3549
3550 ensure_path( 'TEXINPUTS', './custom_cls_sty_files//' );
3551
3552 (In this example, the trailing '//' is documented by TeX systems
3553 to mean that latex, pdflatex, etc search for files in the speci‐
3554 fied directory and in all subdirectories.)
3555
3556 Technically ensure_path works by setting Perl's variable
3557 $ENV{var}, where var is the name of the target variable. The
3558 changed value is then passed as an environment variable to any
3559 invoked programs.
3560
3561
3562 Variables and subroutines for processing a rule
3563 A step in the processing is called a rule. One possibility to implement
3564 the processing of a rule is by a Perl subroutine. This is always the
3565 case for custom dependencies. Also, for any other rule, you can use a
3566 subroutine by prefixing the command specification by the word "inter‐
3567 nal" -- see the section FORMAT OF COMMAND SPECIFICATIONS.
3568
3569 When you use a subroutine for processing a rule, all the possibilities
3570 of Perl programming are available, of course. In addition, some of
3571 latexmk's internal variables and subroutines are available. The ones
3572 listed below are intended to be available to (advanced) users, and
3573 their specifications will generally have stability under upgrades. Gen‐
3574 erally, the variables should be treated as read-only: Changing their
3575 values can have bad consequences, since it is liable to mess up the
3576 consistency of what latexmk is doing.
3577
3578 $rule This variable has the name of the rule, as known to latexmk.
3579 Note that the exact contents of this variable for a given rule
3580 may be dependent on the version of latexmk
3581
3582 $$Psource
3583 This gives the name of the primary source file. Note the double
3584 dollar signs.
3585
3586 $$Pdest
3587 This gives the name of the main output file if any. Note the
3588 double dollar signs.
3589
3590 rdb_ensure_file( $rule, file )
3591 This a subroutine that ensures that the given file is among the
3592 source files for the specified rule. It is typically used when,
3593 during the processing of a rule, it is known that a particular
3594 extra file is among the dependencies that latexmk should know,
3595 but its default methods don't find the dependency. Almost always
3596 the first argument is the name of the rule currently being pro‐
3597 cessed, so it is then appropriate to specify it by $rule.
3598
3599 For examples of its use, see some of the files in the directory
3600 example_rcfiles of latexmk's distribution. Currently the cases
3601 that use this subroutine are bib2gls-latexmkrc, excel‐
3602 tex_latexmkrc and texinfo-latexmkrc. These illustrate typical
3603 cases where latexmk's normal processing fails to detect certain
3604 extra source files.
3605
3606 rdb_remove_files( $rule, file, ... )
3607 This subroutine removes one or more files from the dependency
3608 list for the given rule.
3609
3610 rdb_list_source( $rule )
3611 This subroutine returns the list of source files (i.e., the
3612 dependency list) for the given rule.
3613
3614 rdb_set_source( $rule, file, ... )
3615
3616 rdb_set_source( $rule, @files )
3617 This subroutine sets the dependency list for the given rule to
3618 be the specified files. Files that are already in the list have
3619 unchanged information. Files that were not in the list are
3620 added to it. Files in the previous dependency list that are not
3621 in the newly specified list of files are removed from the depen‐
3622 dency list.
3623
3624 Run_subst( command_spec )
3625 This subroutine runs the command specified by command_spec. The
3626 specification is a string in the format listed in the section
3627 "Format of Command Specifications". An important action of the
3628 Run_subst is to make substitutions of placeholders, e.g., %S and
3629 %D for source and destination files; these get substituted
3630 before the command is run. In addition, the command after sub‐
3631 stitution is printed to the screen unless latexmk is running in
3632 silent mode.
3633
3634
3635 Coordinated Setting of Commands for *latex
3636 To set all of $latex, $pdflatex, $lualatex, and $xelatex to a common
3637 pattern, you can use one of the following subroutines, std_tex_cmds,
3638 alt_tex_cmds, and set_tex_cmds.
3639
3640 They work as follows
3641
3642 &std_tex_cmds;
3643
3644 This results in $latex = 'latex %O %S', and similarly for $pdflatex,
3645 $lualatex, and $xelatex. Note the ampersand in the invocation; this
3646 indicates to Perl that a subroutine is being called.
3647
3648 &alt_tex_cmds;
3649
3650 This results in $latex = 'latex %O %P', and similarly for $pdflatex,
3651 $lualatex, and $xelatex. Note the ampersand in the invocation; this
3652 indicates to Perl that a subroutine is being called.
3653
3654 set_tex_cmds( CMD_SPEC );
3655
3656 Here CMD_SPEC is the command line without the program name. This
3657 results in $latex = 'CMD_SPEC', and similarly for $pdflatex, $lualatex,
3658 and $xelatex. An example would be
3659
3660 set_tex_cmds( '--interaction=batchmode %O %S' );
3661
3662
3663 Advanced configuration: Using latexmk with make
3664 This section is targeted only at advanced users who use the make pro‐
3665 gram for complex projects, as for software development, with the depen‐
3666 dencies specified by a Makefile.
3667
3668 Now the basic task of latexmk is to run the appropriate programs to
3669 make a viewable version of a LaTeX document. However, the usual make
3670 program is not suited to this purpose for at least two reasons. First
3671 is that the use of LaTeX involves circular dependencies (e.g., via .aux
3672 files), and these cannot be handled by the standard make program. Sec‐
3673 ond is that in a large document the set of source files can change
3674 quite frequently, particularly with included graphics files; in this
3675 situation keeping a Makefile manually updated is inappropriate and
3676 error-prone, especially when the dependencies can be determined auto‐
3677 matically. Latexmk solves both of these problems robustly.
3678
3679 Thus for many standard LaTeX documents latexmk can be used by itself
3680 without the make program. In a complex project it simply needs to be
3681 suitably configured. A standard configuration would be to define cus‐
3682 tom dependencies to make graphics files from their source files (e.g.,
3683 as created by the xfig program). Custom dependencies are latexmk's
3684 equivalent of pattern rules in Makefiles.
3685
3686 Nevertheless there are projects for which a Makefile is appropriate,
3687 and it is useful to know how to use latexmk from a Makefile. A typical
3688 example would be to generate documentation for a software project.
3689 Potentially the interaction with the rest of the rules in the Makefile
3690 could be quite complicated, for example if some of the source files for
3691 a LaTeX document are generated by the project's software.
3692
3693 In this section, I give a couple of examples of how latexmk can be use‐
3694 fully invoked from a Makefile. The examples use specific features of
3695 current versions of GNU make, which is the default on both linux and
3696 OS-X systems. They may need modifications for other versions of make.
3697
3698 The simplest method is simply to delegate all the relevant tasks to
3699 latexmk, as is suitable for a straightforward LaTeX document. For this
3700 a suitable Makefile is like
3701
3702 .PHONY : FORCE_MAKE
3703 all : try.pdf
3704 %.pdf : %.tex FORCE_MAKE
3705 latexmk -pdf -dvi- -ps- $<
3706
3707 (Note: the last line must be introduced by a tab for the Makefile to
3708 function correctly!) Naturally, if making try.pdf from its associated
3709 LaTeX file try.tex were the only task to be performed, a direct use of
3710 latexmk without a Makefile would normally be better. The benefit of
3711 using a Makefile for a LaTeX document would be in a larger project,
3712 where lines such as the above would be only be a small part of a larger
3713 Makefile.
3714
3715 The above example has a pattern rule for making a .pdf file from a .tex
3716 file, and it is defined to use latexmk in the obvious way. There is a
3717 conventional default target named "all", with a prerequisite of
3718 try.pdf. So when make is invoked, by default it makes try.pdf. The
3719 only complication is that there may be many source files beyond
3720 try.tex, but these aren't specified in the Makefile, so changes in them
3721 will not by themselves cause latexmk to be invoked. Instead, the pat‐
3722 tern rule is equipped with a "phony" prerequisite FORCE_MAKE; this has
3723 the effect of causing the rule to be always out-of-date, so that
3724 latexmk is always run. It is latexmk that decides whether any action
3725 is needed, e.g., a rerun of pdflatex. Effectively the Makefile dele‐
3726 gates all decisions to latexmk, while make has no knowledge of the list
3727 of source files except for primary LaTeX file for the document. If
3728 there are, for example, graphics files to be made, these must be made
3729 by custom dependencies configured in latexmk.
3730
3731 But something better is needed in more complicated situations, for
3732 example, when the making of graphics files needs to be specified by
3733 rules in the Makefile. To do this, one can use a Makefile like the
3734 following:
3735
3736 TARGETS = document1.pdf document2.pdf
3737 DEPS_DIR = .deps
3738 LATEXMK = latexmk -recorder -use-make -deps \
3739 -e 'warn qq(In Makefile, turn off custom dependencies\n);' \
3740 -e '@cus_dep_list = ();' \
3741 -e 'show_cus_dep();'
3742 all : $(TARGETS)
3743 $(foreach file,$(TARGETS),$(eval -include $(DEPS_DIR)/$(file)P))
3744 $(DEPS_DIR) :
3745 mkdir $@
3746 %.pdf : %.tex
3747 if [ ! -e $(DEPS_DIR) ]; then mkdir $(DEPS_DIR); fi
3748 $(LATEXMK) -pdf -dvi- -ps- -deps-out=$(DEPS_DIR)/$@P $<
3749 %.pdf : %.fig
3750 fig2dev -Lpdf $< $@
3751
3752 (Again, the lines containing the commands for the rules should be
3753 started with tabs.) This example was inspired by how GNU automake han‐
3754 dles automatic dependency tracking of C source files.
3755
3756 After each run of latexmk, dependency information is put in a file in
3757 the .deps subdirectory. The Makefile causes these dependency files to
3758 be read by make, which now has the full dependency information for each
3759 target .pdf file. To make things less trivial it is specificed that
3760 two files document1.pdf and document2.pdf are the targets. The depen‐
3761 dency files are .deps/document1.pdfP and .deps/document2.pdfP.
3762
3763 There is now no need for the phony prerequisite for the rule to make
3764 .pdf files from .tex files. But I have added a rule to make .pdf files
3765 from .fig files produced by the xfig program; these are commonly used
3766 for graphics insertions in LaTeX documents. Latexmk is arranged to
3767 output a dependency file after each run. It is given the -recorder
3768 option, which improves its detection of files generated during a run of
3769 pdflatex; such files should not be in the dependency list. The -e
3770 options are used to turn off all custom dependencies, and to document
3771 this. Instead the -use-make is used to delegate the making of missing
3772 files to make itself.
3773
3774 Suppose in the LaTeX file there is a command \includegraphics{graph},
3775 and an xfig file "graph.fig" exists. On a first run, pdflatex reports
3776 a missing file, named "graph". Latexmk succeeds in making "graph.pdf"
3777 by calling "make graph.pdf", and after completion of its work, it lists
3778 "fig.pdf" among the dependents of the file latexmk is making. Then let
3779 "fig.fig" be updated, and then let make be run. Make first remakes
3780 "fig.pdf", and only then reruns latexmk.
3781
3782 Thus we now have a method by which all the subsidiary processing is
3783 delegated to make.
3784
3785
3787 latex(1), bibtex(1), lualatex(1), pdflatex(1), xelatex(1).
3788
3790 Sometimes a viewer (gv) tries to read an updated .ps or .pdf file after
3791 its creation is started but before the file is complete. Work around:
3792 manually refresh (or reopen) display. Or use one of the other preview‐
3793 ers and update methods.
3794
3795 (The following isn't really a bug, but concerns features of preview‐
3796 ers.) Preview continuous mode only works perfectly with certain pre‐
3797 viewers: Xdvi on UNIX/Linux works for dvi files. Gv on UNIX/Linux
3798 works for both postscript and pdf. Ghostview on UNIX/Linux needs a
3799 manual update (reopen); it views postscript and pdf. Gsview under MS-
3800 Windows works for both postscript and pdf, but only reads the updated
3801 file when its screen is refreshed. Acroread under UNIX/Linux views
3802 pdf, but the file needs to be closed and reopened to view an updated
3803 version. Under MS-Windows, acroread locks its input file and so the
3804 pdf file cannot be updated. (Remedy: configure latexmk to use suma‐
3805 trapdf instead.)
