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="COMMAND"
587 This sets the string specifying the command to run latex, and is
588 typically used to add desired options. Since the string nor‐
589 mally contains spaces, it should be quoted, e.g.,
590
591 latexmk -latex="latex --shell-escape %O %S" foo.tex
592
593 The specification of the contents of the string are the same as
594 for the $latex configuration variable. Depending on your oper‐
595 ating system and the command-line shell you are using, you may
596 need to change the single quotes to double quotes (or something
597 else).
598
599 To set the command for running pdflatex (rather than the command
600 for latex) see the -pdflatex option.
601
602
603 -logfilewarninglist
604 -logfilewarnings After a run of (pdf)latex, give a list of warn‐
605 ings about undefined citations and references (unless silent
606 mode is on).
607
608 See also the $silence_logfile_warnings configuration variable.
609
610
611 -logfilewarninglist-
612 -logfilewarnings- After a run of (pdf)latex, do not give a list
613 of warnings about undefined citations and references. (Default)
614
615 See also the $silence_logfile_warnings configuration variable.
616
617
618 -lualatex
619 Use lualatex. That is, use lualatex to process the source
620 file(s) to pdf. The generation of dvi and postscript files is
621 turned off.
622
623 This option is equivalent to using the following set of options
624
625 -pdflua -dvi- -ps-
626
627 (Note: Note that the method of implementation of this option,
628 but not its intended effect, differ from some earlier versions
629 of latexmk.)
630
631
632 -M Show list of dependent files after processing. This is equiva‐
633 lent to the -deps option.
634
635
636 -MF file
637 If a list of dependents is made, the -MF specifies the file to
638 write it to.
639
640
641 -MP If a list of dependents is made, include a phony target for each
642 source file. If you use the dependents list in a Makefile, the
643 dummy rules work around errors the program make gives if you
644 remove header files without updating the Makefile to match.
645
646
647 -new-viewer
648 When in continuous-preview mode, always start a new viewer to
649 view the generated file. By default, latexmk will, in continu‐
650 ous-preview mode, test for a previously running previewer for
651 the same file and not start a new one if a previous previewer is
652 running. However, its test sometimes fails (notably if there is
653 an already-running previewer that is viewing a file of the same
654 name as the current file, but in a different directory). This
655 option turns off the default behavior.
656
657
658 -new-viewer-
659 The inverse of the -new-viewer option. It puts latexmk in its
660 normal behavior that in preview-continuous mode it checks for an
661 already-running previewer.
662
663
664 -nobibtex
665 Never run bibtex or biber. Equivalent to the -bibtex- option.
666
667
668 -norc Turn off the automatic reading of initialization (rc) files.
669
670 N.B. Normally the initialization files are read and obeyed, and
671 then command line options are obeyed in the order they are
672 encountered. But -norc is an exception to this rule: it is
673 acted on first, no matter where it occurs on the command line.
674
675
676 -outdir=FOO or -output-directory=FOO
677
678 Sets the directory for the output files of (pdf)latex. This
679 achieves its effect by the -output-directory option of
680 (pdf)latex, which currently (Dec. 2011 and later) is implemented
681 on the common versions of (pdf)latex, i.e., MiKTeX and TeXLive.
682 It may not be present in other versions.
683
684 See also the -auxdir/-aux-directory options, and the $aux_dir,
685 $out_dir, and $search_path_separator configuration variables of
686 latexmk. In particular, see the documentation of $out_dir for
687 some complications on what directory names are suitable.
688
689 If you also use the -cd option, and the specified output direc‐
690 tory is a relative path, then the path is interpreted relative
691 to the document directory.
692
693
694 -p Print out the document. By default the file to be printed is
695 the first in the list postscript, pdf, dvi that is being made.
696 But you can use the -print=... option to change the type of file
697 to be printed, and you can configure this in a start up file (by
698 setting the $print_type variable).
699
700 However, printing is enabled by default only under UNIX/Linux
701 systems, where the default is to use the lpr command and only on
702 postscript files. In general, the correct behavior for printing
703 very much depends on your system's software. In particular,
704 under MS-Windows you must have suitable program(s) available,
705 and you must have configured the print commands used by latexmk.
706 This can be non-trivial. See the documentation on the $lpr,
707 $lpr_dvi, and $lpr_pdf configuration variables to see how to set
708 the commands for printing.
709
710 This option is incompatible with the -pv and -pvc options, so it
711 turns them off.
712
713
714 -pdf Generate pdf version of document using pdflatex. (If you wish
715 to use lualatex or xelatex, you can use whichever of the options
716 -pdflua, -pdfxe, -lualatex or -xelatex applies.) To configure
717 latexmk to have such behavior by default, see the section on
718 "Configuration/initialization (rc) files".
719
720
721 -pdfdvi
722 Generate pdf version of document from the dvi file, by default
723 using dvipdf.
724
725
726 -pdflua
727 Generate pdf version of document using lualatex.
728
729
730 -pdfps Generate pdf version of document from the .ps file, by default
731 using ps2pdf.
732
733
734 -pdfxe Generate pdf version of document using xelatex. Note that to
735 optimize processing time, latexmk uses xelatex to generate an
736 .xdv file rather than a pdf file directly. Only after possibly
737 multiple runs to generate a fully up-to-date .xdv file does
738 latexmk then call xdvipdfmx to generate the final .pdf file.
739
740 (Note: When the document includes large graphics files, espe‐
741 cially .png files, the last step can be quite time consuming,
742 even when the creation of the .xdv file by xelatex is fast. So
743 the use of the intermediate .xdv file can result in substantial
744 gains in procesing time, since the .pdf file is produced once
745 rather than on every run of xelatex. See the documentation on
746 the -pdfxe option for why an .xdv file is used.
747
748
749 -pdf- Turn off generation of pdf version of document. (This can be
750 used to override a setting in a configuration file. It may get
751 overridden if some other option requires the generation of a pdf
752 file.)
753
754 If after all options have been processed, pdf generation is
755 still turned off, then generation of a dvi file will be turned
756 on, and then the program used to compiled a document will be
757 latex (or, more precisely, whatever program is configured to be
758 used in the $latex configuration variable).
759
760
761 -pdflatex="COMMAND"
762 This sets the string specifying the command to run pdflatex, and
763 is typically used to add desired options. Since the string nor‐
764 mally contains spaces, it should be quoted, e.g.,
765
766 latexmk -pdf -pdflatex="pdflatex --shell-escape %O %S"
767 foo.tex
768
769 The specification of the contents of the string are the same as
770 for the $pdflatex configuration variable. (The option -pdflatex
771 in fact sets the variable $pdflatex.) Depending on your operat‐
772 ing system and the command-line shell you are using, you may
773 need to change the single quotes to double quotes (or something
774 else).
775
776 To set the command for running latex (rather than the command
777 for pdflatex) see the -latex option.
778
779
780 -pdflualatex="COMMAND"
781 This sets the string specifying the command to run lualatex. It
782 behaves like the -pdflatex option, but sets the variable $luala‐
783 tex.
784
785
786 -pdfxelatex="COMMAND"
787 This sets the string specifying the command to run xelatex. It
788 behaves like the -pdflatex option, but sets the variable $xela‐
789 tex.
790
791 Warning: It is important to ensure that the -no-pdf is used when
792 xelatex is invoked; see the explanation for the variable $xela‐
793 tex for why this is necessary. If you provide %O in the command
794 specification, this will be done automatically.
795
796 An example of the use of the -pdfxelatex option:
797
798 latexmk -pdfxe -pdfxelatex="xelatex --shell-escape %O %S"
799 foo.tex
800
801
802
803 -pretex=CODE
804
805 Given that CODE is some TeX code, this options sets that code to
806 be executed before inputting source file. This only works if
807 the command for invoking the relevant *latex is suitably config‐
808 ured. See the documentation of the variable $pre_tex_code, and
809 the substitution strings %P and %U for more details. This
810 option works by setting the variable $pre_tex_code.
811
812 See also the -usepretex option.
813
814 An example:
815
816 latexmk -pretex='\AtBeginDocument{Message\par}' -usepretex
817 foo.tex
818
819 But this is better written
820
821 latexmk -usepretex='\AtBeginDocument{Message\par}' foo.tex
822
823 If you already have a suitable command configured, you only need
824
825 latexmk -pretex='\AtBeginDocument{Message\par}' foo.tex
826
827
828 -print=dvi, -print=ps, -print=pdf, -print=auto,
829 Define which kind of file is printed. This option also ensures
830 that the requisite file is made, and turns on printing.
831
832 The (default) case -print=auto determines the kind of print file
833 automatically from the set of files that is being made. The
834 first in the list postscript, pdf, dvi that is among the files
835 to be made is the one used for print out.
836
837
838 -ps Generate postscript version of document.
839
840
841 -ps- Turn off generation of postscript version of document. This can
842 be used to override a setting in a configuration file. (It may
843 get overridden by some other option that requires a postscript
844 file, for example a request for printing.)
845
846
847 -pF Postscript file filtering. The argument to this option is a
848 filter which will generate a filtered postscript file with the
849 extension ".psF". All extra processing (e.g. preview, printing)
850 will then be performed on this filtered postscript file.
851
852 Example of usage: Use psnup to print two pages on the one page:
853
854 latexmk -ps -pF 'psnup -2' foo.tex
855
856 or
857
858 latexmk -ps -pF "psnup -2" foo.tex
859
860 Whether to use single or double quotes round the "psnup -2" will
861 depend on your command interpreter, as used by the particular
862 version of perl and the operating system on your computer.
863
864
865 -pv Run file previewer. If the -view option is used, this will
866 select the kind of file to be previewed (.dvi, .ps or .pdf).
867 Otherwise the viewer views the "highest" kind of file selected,
868 by the -dvi, -ps, -pdf, -pdfps options, in the order .dvi, .ps,
869 .pdf (low to high). If no file type has been selected, the dvi
870 previewer will be used. This option is incompatible with the -p
871 and -pvc options, so it turns them off.
872
873
874 -pv- Turn off -pv.
875
876
877 -pvc Run a file previewer and continually update the .dvi, .ps,
878 and/or .pdf files whenever changes are made to source files (see
879 the Description above). Which of these files is generated and
880 which is viewed is governed by the other options, and is the
881 same as for the -pv option. The preview-continuous option -pvc
882 can only work with one file. So in this case you will normally
883 only specify one filename on the command line. It is also
884 incompatible with the -p and -pv options, so it turns these
885 options off.
886
887 The -pvc option also turns off force mode (-f), as is normally
888 best for continuous preview mode. If you really want force
889 mode, use the options in the order -pvc -f.
890
891 With a good previewer the display will be automatically updated.
892 (Under some but not all versions of UNIX/Linux "gv -watch" does
893 this for postscript files; this can be set by a configuration
894 variable. This would also work for pdf files except for an
895 apparent bug in gv that causes an error when the newly updated
896 pdf file is read.) Many other previewers will need a manual
897 update.
898
899 Important note: the acroread program on MS-Windows locks the pdf
900 file, and prevents new versions being written, so it is a bad
901 idea to use acroread to view pdf files in preview-continuous
902 mode. It is better to use a different viewer: SumatraPDF and
903 gsview are good possibilities.
904
905 There are some other methods for arranging an update, notably
906 useful for many versions of xdvi and xpdf. These are best set
907 in latexmk's configuration; see below.
908
909 Note that if latexmk dies or is stopped by the user, the
910 "forked" previewer will continue to run. Successive invocations
911 with the -pvc option will not fork new previewers, but latexmk
912 will normally use the existing previewer. (At least this will
913 happen when latexmk is running under an operating system where
914 it knows how to determine whether an existing previewer is run‐
915 ning.)
916
917
918 -pvc- Turn off -pvc.
919
920
921 -pvctimeout
922 Do timeout in pvc mode after period of inactivity, which is 30
923 min. by default. Inactivity means a period when latexmk has
924 detected no file changes and hence has not taken any actions
925 like compiling the document.
926
927
928 -pvctimeout-
929 Don't do timeout in pvc mode after inactivity.
930
931
932 -pvctimeoutmins=<time>
933 Set period of inactivity in minutes for pvc timeout.
934
935
936 -quiet Same as -silent
937
938
939 -r <rcfile>
940 Read the specified initialization file ("RC file") before pro‐
941 cessing.
942
943 Be careful about the ordering: (1) Standard initialization files
944 -- see the section below on "Configuration/initialization (RC)
945 files" -- are read first. (2) Then the options on the command
946 line are acted on in the order they are given. Therefore if an
947 initialization file is specified by the -r option, it is read
948 during this second step. Thus an initialization file specified
949 with the -r option can override both the standard initialization
950 files and previously specified options. But all of these can be
951 overridden by later options.
952
953 The contents of the RC file just comprise a piece of code in the
954 Perl programming language (typically a sequence of assignment
955 statements); they are executed when the -r option is encountered
956 during latexmk's parsing of its command line. See the -e option
957 for a way of giving initialization code directly on latexmk's
958 command line. An error results in latexmk stopping. Multiple
959 instances of the -r and -e options can be used, and they are
960 executed in the order they appear on the command line.
961
962
963 -recorder
964 Give the -recorder option with latex and pdflatex. In (most)
965 modern versions of these programs, this results in a file of
966 extension .fls containing a list of the files that these pro‐
967 grams have read and written. Latexmk will then use this file to
968 improve its detection of source files and generated files after
969 a run of latex or pdflatex. This is the default setting of
970 latexmk, unless overridden in an initialization file.
971
972 For further information, see the documentation for the $recorder
973 configuration variable.
974
975
976 -recorder-
977 Do not supply the -recorder option with latex and pdflatex.
978
979
980 -rules Show a list of latemk's rules and dependencies after processing.
981
982
983 -rules-
984 Do not show a list of latexmk's rules and dependencies after
985 processing. (This is the default.)
986
987
988 -showextraoptions
989 Show the list of extra latex and pdflatex options that latexmk
990 recognizes, but that it simply passes through to the programs
991 latex, pdflatex, etc when they are run. These options are
992 (currently) a combination of those allowed by the TeXLive and
993 MiKTeX implementations. (If a particular option is given to
994 latexmk but is not handled by the particular implementation of
995 latex or pdflatex that is being used, that program will probably
996 give an error message.) These options are very numerous, but
997 are not listed in this documentation because they have no effect
998 on latexmk's actions.
999
1000 There are a few options (-includedirectory=dir, -initialize,
1001 -ini) that are not recognized, either because they don't fit
1002 with latexmk's intended operations, or because they need special
1003 processing by latexmk that isn't implemented (at least, not
1004 yet).
1005
1006 There are also options that are accepted by latex etc, but
1007 instead trigger actions by latexmk: -help, -version.
1008
1009 Finally, there are certain options for latex and pdflatex (e.g.,
1010 -recorder) that trigger special actions or behavior by latexmk
1011 itself as well as being passed in some form to the called latex
1012 and pdflatex program, or that affect other programs as well.
1013 These options do have entries in this documentation. These
1014 options are: -jobname=STRING, -aux-directory=dir, -output-direc‐
1015 tory=DIR, -quiet, and -recorder.
1016
1017
1018 -silent
1019 Run commands silently, i.e., with options that reduce the amount
1020 of diagnostics generated. For example, with the default set‐
1021 tings, the command "latex -interaction=batchmode" is used for
1022 latex, and similarly for its friends.
1023
1024 See also the -logfilewarninglist and -logfilewarninglist-
1025 options.
1026
1027 Also reduce the number of informational messages that latexmk
1028 itself generates.
1029
1030 To change the options used to make the commands run silently,
1031 you need to configure latexmk with changed values of its config‐
1032 uration variables, the relevant ones being $bib‐
1033 tex_silent_switch, $biber_silent_switch, $dvipdf_silent_switch,
1034 $dvips_silent_switch, $latex_silent_switch, $luala‐
1035 tex_silent_switch $makeindex_silent_switch, $pdfla‐
1036 tex_silent_switch, and $xelatex_silent_switch
1037
1038
1039 -stdtexcmds
1040 Sets the commands for latex, etc, so that they are the standard
1041 ones. This is useful to override special configurations.
1042
1043 The result is that $latex = 'latex %O %S', and similarly for
1044 $pdflatex, $lualatex, and $xelatex. (The option -no-pdf needed
1045 for $xelatex is provided automatically, given that %O appears in
1046 the definition.)
1047
1048
1049 -time Show CPU time used. See also the configuration variable
1050 $show_time.
1051
1052
1053 -time- Do not show CPU time used. See also the configuration variable
1054 $show_time.
1055
1056
1057 -use-make
1058 When after a run of latex or pdflatex, there are warnings about
1059 missing files (e.g., as requested by the LaTeX \input, \include,
1060 and \includgraphics commands), latexmk tries to make them by a
1061 custom dependency. If no relevant custom dependency with an
1062 appropriate source file is found, and if the -use-make option is
1063 set, then as a last resort latexmk will try to use the make pro‐
1064 gram to try to make the missing files.
1065
1066 Note that the filename may be specified without an extension,
1067 e.g., by \includegraphics{drawing} in a LaTeX file. In that
1068 case, latexmk will try making drawing.ext with ext set in turn
1069 to the possible extensions that are relevant for latex (or as
1070 appropriate pdflatex).
1071
1072 See also the documentation for the $use_make_for_missing_files
1073 configuration variable.
1074
1075
1076 -use-make-
1077 Do not use the make program to try to make missing files.
1078 (Default.)
1079
1080
1081 -usepretex
1082 Sets the command lines for latex, etc, so that they use the code
1083 that is defined by the variable $pre_tex_code or that is set by
1084 the option -pretex=CODE to execute the specified TeX code before
1085 the source file is read. This option overrides any previous
1086 definition of the command lines.
1087
1088 The result is that $latex = 'latex %O %P', and similarly for
1089 $pdflatex, $lualatex, and $xelatex. (The option -no-pdf needed
1090 for $xelatex is provided automatically, given that %O appears in
1091 the definition.)
1092
1093
1094 -usepretex=CODE
1095 Equivalent to -pretex=CODE -usepretex. Example
1096
1097 latexmk -usepretex='\AtBeginDocument{Message\par}' foo.tex
1098
1099
1100 -v, -version
1101 Print version number of latexmk.
1102
1103
1104 -verbose
1105 Opposite of -silent. This is the default setting.
1106
1107
1108 -view=default, -view=dvi, -view=ps, -view=pdf, -view=none
1109 Set the kind of file used when previewing is requested (e.g., by
1110 the -pv or -pvc switches). The default is to view the "highest"
1111 kind of requested file (in the low-to-high order .dvi, .ps,
1112 .pdf).
1113
1114 Note the possibility -view=none where no viewer is opened at
1115 all. One example of is use is in conjunction with the -pvc
1116 option, when you want latexmk to do a compilation automatically
1117 whenever source file(s) change, but do not want a previewer to
1118 be opened.
1119
1120
1121 -Werror
1122 This causes latexmk to return a non-zero status code if any of
1123 the files processed gives a warning about problems with cita‐
1124 tions or references (i.e., undefined citations or references or
1125 about multiply defined references). This is after latexmk has
1126 completed all the runs it needs to try and resolve references
1127 and citations. Thus -Werror causes latexmk to treat such warn‐
1128 ings as errors, but only when they occur on the last run of
1129 (pdf)latex and only after processing is complete. Also can be
1130 set by the configuration variable $warnings_as_errors.
1131
1132
1133 -xelatex
1134 Use xelatex. That is, use xelatex to process the source file(s)
1135 to pdf. The generation of dvi and postscript files is turned
1136 off.
1137
1138 This option is equivalent to using the following set of options
1139
1140 -pdfxe -dvi- -ps-
1141
1142 [Note: Note that the method of implementation of this option,
1143 but not its intended primary effect, differ from some earlier
1144 versions of latexmk. Latexmk first uses xelatex to make an .xdv
1145 file, and does all the extra runs needed (including those of
1146 bibtex, etc). Only after that does it make the pdf file from
1147 the .xdv file, using xdvipdfmx. This procedure can result in
1148 considerable savings in run time, since the xdv-to-pdf conver‐
1149 sion is quite time-consuming when large graphics files are used
1150 in the document.]
1151
1152
1153
1154 Compatibility between options
1155
1156 The preview-continuous option -pvc can only work with one file. So in
1157 this case you will normally only specify one filename on the command
1158 line.
1159
1160 Options -p, -pv and -pvc are mutually exclusive. So each of these
1161 options turns the others off.
1162
1163
1165 % latexmk thesis # run latex enough times to resolve
1166 cross-references
1167
1168 % latexmk -pvc -ps thesis# run latex enough times to resolve
1169 cross-references, make a postscript
1170 file, start a previewer. Then
1171 watch for changes in the source
1172 file thesis.tex and any files it
1173 uses. After any changes rerun latex
1174 the appropriate number of times and
1175 remake the postscript file. If latex
1176 encounters an error, latexmk will
1177 keep running, watching for
1178 source file changes.
1179
1180 % latexmk -c # remove .aux, .log, .bbl, .blg, .dvi,
1181 .pdf, .ps & .bbl files
1182
1183
1184
1186 Some possibilities:
1187
1188 a. If you get a strange error, do look carefully at the output that is
1189 on the screen and in log files. While there is much that is notori‐
1190 ously verbose in the output of latex (and that is added to by latexmk),
1191 the verbosity is there for a reason: to enable the user to diagnose
1192 problems. Latexmk does repeat some messages at the end of a run that
1193 it thinks would otherwise be easy to miss in the middle of other out‐
1194 put.
1195
1196 b. Generally, remember that latexmk does its work by running other pro‐
1197 grams. Your first priority in dealing with errors should be to examine
1198 what went wrong with the individual programs. Then you need to correct
1199 the causes of errors in the runs of these programs. (Often these come
1200 from errors in the source document, but they could also be about miss‐
1201 ing LaTeX packages, etc.)
1202
1203 c. If latexmk doesn't run the programs the way you would like, then you
1204 need to look in this documentation at the list of command line options
1205 and then at the sections on configuration/initialization files. A lot
1206 of latexmk's behavior is configurable to deal with particular situa‐
1207 tions. (But there is a lot of reading!)
1208
1209 The remainder of these notes consists of ideas for dealing with more
1210 difficult situations.
1211
1212 d. Further tricks can involve replacing the standard commands that
1213 latexmk runs by other commands or scripts.
1214
1215 e. For possible examples of code for use in an RC file, see the direc‐
1216 tory example_rcfiles in the distribution of latexmk (e.g., at
1217 http://mirror.ctan.org/support/latexmk/example_rcfiles). Even if these
1218 examples don't do what you want, they may provide suitable inspiration.
1219
1220 f. There's a useful trick that can be used when you use lualatex
1221 instead of pdflatex (and in some related situations). The problem is
1222 that latexmk won't notice a dependency on a file, bar.baz say, that is
1223 input by the lua code in your document instead of by the LaTeX part.
1224 (Thus if you change bar.baz and rerun latexmk, then latexmk will think
1225 no files have changed and not rerun lualatex, whereas if you had
1226 '\input{bar.baz}' in the LaTeX part of the document, latexmk would
1227 notice the change.) One solution is just to put the following some‐
1228 where in the LaTeX part of the document:
1229
1230 \typeout{(bar.baz)}
1231
1232 This puts a line in the log file that latexmk will treat as implying
1233 that the file bar.baz was read. (At present I don't know a way of
1234 doing this automatically.) Of course, if the file has a different
1235 name, change bar.baz to the name of your file.
1236

1239 h. Look on tex.stackexchange, i.e., at http://tex.stackex‐
1240 change.com/questions/tagged/latexmk Someone may have already solved
1241 your problem.

1246 documentation.
1247
1248
1249
1251 When one of the latex engines is run, the usual situation is that latex
1252 produces a .dvi file, while pdflatex and lualatex produce a .pdf file.
1253 For xelatex the default is to produce a .pdf file, but to optimize pro‐
1254 cessing time latexmk runs xelatex its -no-pdf option so that it pro‐
1255 duces an .xdv file. Further processing by latexmk takes this as a
1256 starting point.
1257
1258 However, the actual output file may differ from the normal expectation;
1259 and then latexmk can adjust its processing to accommodate this situa‐
1260 tion. The difference in output file type can happen for two reasons:
1261 One is that for latex, pdflatex and lualatex the document itself can
1262 override the defaults. The other is that there may be a configuration,
1263 or misconfiguration, such that the program that latexmk invokes to com‐
1264 pile the document is not the expected one, or is given options incom‐
1265 patible with what latexmk initially expects. (E.g., the -output-for‐
1266 mat=... option could be used with lualatex, or xelatex gets invoked
1267 without the -no-pdf option.)
1268
1269 Under latex and pdflatex, control of the output format by the document
1270 is done by setting the \pdfoutput macro. Under lualatex, the \output‐
1271 mode macro is used instead.
1272
1273 One example of an important use-case for document control of the output
1274 format is a document that uses the psfrag package to insert graphical
1275 elements in the output file. The psfrag package achieves its effects by
1276 inserting postscript code in the output of the compilation of the docu‐
1277 ment. This entails the use of compilation to a .dvi file, followed by
1278 the use of conversion to a postscript file (either directly, as by
1279 dvips or implicitly, as an intermediate step by dvipdf). Then it is
1280 useful to force output to be of the .dvi format by inserting \pdfout‐
1281 put=0 in the preamble of the document.
1282
1283 Another example is where the document uses graphics file of the .pdf,
1284 .jpg, and png types. With the default setting for the graphicx pack‐
1285 age, these can be processed in compilation to .pdf but not with compi‐
1286 lation to .dvi. In this case, it is useful to insert \pdfoutput=1 in
1287 the preamble of the document to force compilation to .pdf output for‐
1288 mat.
1289
1290 In all of these cases, it is needed that latexmk has to adjust its pro‐
1291 cessing to deal with a mismatch between the actual output format (out
1292 of .pdf, .dvi, .xdv) and the initially expected output, if possible.
1293 Latexmk does this provided the following conditions are met.
1294
1295 The first is that latexmk's $allow_switch configuration variable is set
1296 to a non-zero value as it is by default. If this variable is zero, a
1297 mismatch of filetypes in the compilation results in an erro.
1298
1299 The second condition for latexmk to be able to handle a change of out‐
1300 put type is that no explicit requests for .dvi or .ps output files are
1301 made. Explicit requests are by the -dvi and -ps, -print=dvi,
1302 -print=ps, -view=dvi, and -view=ps options, and by corresponding set‐
1303 tings of the $dvi_mode, $postscript_mode, $print_type, and $view con‐
1304 figuration variables. The print-type and view-type restrictions only
1305 apply when printing and viewing are explicitly requested, respectively.
1306 For this purpose, the use of the -pdfdvi and -pdfps options (and the
1307 corresponding setting of the $pdf_mode variable) does not count as an
1308 explicit request for the .dvi and .ps files; they are merely regarded
1309 as a request for making a .pdf file together with an initial proposal
1310 for the processing route to make it.
1311
1312 Note that when accommodating a change in output file type, there is
1313 involved a substantial change in the network of rules that latexmk uses
1314 in its actions. The second condition applied to accommodate a change
1315 is to avoid situations where the change in the rule network is too rad‐
1316 ical to be readily handled automatically.
1317
1318
1319
1321 In this section is explained which configuration files are read by
1322 latexmk. Subsequent sections "How to Set Variables in Initialization
1323 Files", "Format of Command Specifications", "List of Configuration
1324 Variables Usable in Initialization Files", "Custom Dependencies", and
1325 "Advanced Configuration" give details on what can be configured and
1326 how.
1327
1328 Latexmk can be customized using initialization files, which are read at
1329 startup in the following order:
1330
1331 1) The system RC file, if it exists.
1332 On a UNIX system, latexmk searches for following places for its sys‐
1333 tem RC file, in the following order, and reads the first it finds:
1334 "/opt/local/share/latexmk/LatexMk",
1335 "/usr/local/share/latexmk/LatexMk",
1336 "/usr/local/lib/latexmk/LatexMk".
1337 On a Fedora system, it only looks for "/etc/latexmk.conf".
1338 On a MS-Windows system it looks for "C:\latexmk\LatexMk".
1339 On a cygwin system (i.e., a MS-Windows system in which Perl is that
1340 of cygwin), latexmk reads the first it finds of
1341 "/cygdrive/c/latexmk/LatexMk",
1342 "/opt/local/share/latexmk/LatexMk",
1343 "/usr/local/share/latexmk/LatexMk",
1344 "/usr/local/lib/latexmk/LatexMk".
1345
1346 In addition, it then tries the same set of locations, but with the file
1347 name replaced "LatexMk" replaced by "latexmkrc".
1348
1349 If the environment variable LATEXMKRCSYS is set, its value is used as
1350 the name of the system RC file, instead of any of the above.
1351
1352 2) The user's RC file, if it exists. This can be in one of two places.
1353 The traditional one is ".latexmkrc" in the user's home directory. The
1354 other possibility is "latexmk/latexmkrc" in the user's XDG configura‐
1355 tion home directory. The actual file read is the first of "$XDG_CON‐
1356 FIG_HOME/latexmk/latexmkrc" or "$HOME/.latexmkrc" which exists. (See
1357 https://specifications.freedesktop.org/basedir-spec/basedir-spec-lat‐
1358 est.html for details on the XDG Base Directory Specification.)
1359
1360 Here $HOME is the user's home directory. [Latexmk determines the
1361 user's home directory as follows: It is the value of the environment
1362 variable HOME, if this variable exists, which normally is the case on
1363 UNIX-like systems (including Linux and OS-X). Otherwise the environ‐
1364 ment variable USERPROFILE is used, if it exists, which normally is the
1365 case on MS-Windows systems. Otherwise a blank string is used instead of
1366 $HOME, in which case latexmk does not look for an RC file in it.]
1367
1368 $XDG_CONFIG_HOME is the value of the environment variable XDG_CON‐
1369 FIG_HOME if it exists. If this environment variable does not exist,
1370 but $HOME is non-blank, then $XDG_CONFIG_HOME is set to the default
1371 value of $HOME/.config. Otherwise $XDG_CONFIG_HOME is blank, and
1372 latexmk does not look for an RC file under it.
1373
1374
1375 3) The RC file in the current working directory. This file can be
1376 named either "latexmkrc" or ".latexmkrc", and the first of these to be
1377 found is used, if any.
1378
1379 4) Any RC file(s) specified on the command line with the -r option.
1380
1381 Each RC file is a sequence of Perl commands. Naturally, a user can use
1382 this in creative ways. But for most purposes, one simply uses a
1383 sequence of assignment statements that override some of the built-in
1384 settings of Latexmk. Straightforward cases can be handled without
1385 knowledge of the Perl language by using the examples in this document
1386 as templates. Comment lines are introduced by the "#" character.
1387
1388 Note that command line options are obeyed in the order in which they
1389 are written; thus any RC file specified on the command line with the -r
1390 option can override previous options but can be itself overridden by
1391 later options on the command line. There is also the -e option, which
1392 allows initialization code to be specified in latexmk's command line.
1393
1394 For possible examples of code for in an RC file, see the directory
1395 example_rcfiles in the distribution of latexmk (e.g., at http://mir‐
1396 ror.ctan.org/support/latexmk/example_rcfiles).
1397
1398
1400 The important variables that can be configured are described in the
1401 section "List of configuration variables usable in initialization
1402 files". (See the earlier section "Configuration/Initialization (rc)
1403 Files" for the files where the configurations are done.) Syntax for
1404 setting these variables is of the following forms:
1405
1406 $bibtex = 'bibtex %O %B';
1407
1408 for the setting of a string variable,
1409
1410 $preview_mode = 1;
1411
1412 for the setting of a numeric variable, and
1413
1414 @default_files = ('paper', 'paper1');
1415
1416 for the setting of an array of strings. It is possible to append an
1417 item to an array variable as follows:
1418
1419 push @default_files, 'paper2';
1420
1421 Note that simple "scalar" variables have names that begin with a $
1422 character and array variables have names that begin with a @ character.
1423 Each statement ends with a semicolon.
1424
1425 Strings should be enclosed in single quotes. (You could use double
1426 quotes, as in many programming languages. But then the Perl program‐
1427 ming language brings into play some special rules for interpolating
1428 variables into strings. People not fluent in Perl will want to avoid
1429 these complications.)
1430
1431 You can do much more complicated things, but for this you will need to
1432 consult a manual for the Perl programming language.
1433
1434
1435
1436
1438 Some of the variables set the commands that latexmk uses for carrying
1439 out its work, for example to generate a .dvi file from a .tex file or
1440 to view a postscript file. This section describes some important fea‐
1441 tures of how the commands are specified. (Note that some of the possi‐
1442 bilities listed here do not apply to the $kpsewhich variable; see its
1443 documentation.)
1444
1445 Placeholders: Supposed you wanted latexmk to use the command elatex in
1446 place of the regular latex command, and suppose moreover that you
1447 wanted to give it the option "--shell-escape". You could do this by
1448 the following setting:
1449
1450 $latex = 'elatex --shell-escape %O %S';
1451
1452 The two items starting with the % character are placeholders. These
1453 are substituted by appropriate values before the command is run. Thus
1454 %S will be replaced by the source file that elatex will be applied to,
1455 and %O will be replaced by any options that latexmk has decided to use
1456 for this command. (E.g., if you used the -silent option in the invoca‐
1457 tion of latexmk, it results in the replacement of %O by "-interac‐
1458 tion=batchmode".)
1459
1460 The available placeholders are:
1461
1462 %A basename of the main tex file. Unlike %R, this is unaffected by
1463 the setting of a jobname by the -jobname option or the $jobname
1464 configuration value.
1465
1466 %B base of filename for current command. E.g., if a postscript
1467 file document.ps is being made from the dvi file document.dvi,
1468 then the basename is document.
1469
1470 %D destination file (e.g., the name of the postscript file when
1471 converting a dvi file to postscript).
1472
1473 %O options
1474
1475 %P If the variable $pre_tex_code is non-empty, then %P is substi‐
1476 tuted by the contents of $pre_tex_code followed by
1477 \input{SOURCE}, where SOURCE stands for the name of the source
1478 file. Appropriate quoting is done. This enables TeX code to be
1479 passed to one of the *latex engines to be executed before the
1480 source file is read.
1481
1482 If the variable $pre_tex_code is the empty string, then %P is
1483 equivalent to %S.
1484
1485 %R root filename. This is the base name for the main tex file.
1486
1487 By default this is the basename of the main tex file. However
1488 the value can be changed by the use of the -jobname option or
1489 the $jobname configuration variable.
1490
1491 %S source file (e.g., the name of the dvi file when converting a
1492 .dvi file to ps).
1493
1494 %T The name of the primary tex file.
1495
1496 %U If the variable $pre_tex_code is non-empty, then its value is
1497 substituted for %U (appropriately quoted). Otherwise it is
1498 replaced by a null string.
1499
1500 %Y Name of directory for auxiliary output files (see the configura‐
1501 tion variable $aux_dir). A directory separation character ('/')
1502 is appended if $aux_dir is non-empty and does not end in a suit‐
1503 able character, with suitable characters being those appropriate
1504 to UNIX and MS-Windows, i.e., ':', '/' and '\'. Note that if
1505 after initialization, $out_dir is set, but $aux_dir is not set
1506 (i.e., it is blank), then latexmk sets $aux_dir to the same
1507 value $out_dir.
1508
1509 %Z Name of directory for output files (see the configuration vari‐
1510 able $out_dir). A directory separation character ('/') is
1511 appended if $out_dir is non-empty and does not end in a suitable
1512 character, with suitable characters being those appropriate to
1513 UNIX and MS-Windows, i.e., ':', '/' and '\'.
1514
1515 If for some reason you need a literal % character in your string not
1516 subject to the above rules, use "%%".
1517
1518 Appropriate quoting will be applied to the filename substitutions, so
1519 you mustn't supply them yourself even if the names of your files have
1520 spaces in them. (But if your TeX filenames have spaces in them, beware
1521 that some older versions of the TeX program cannot correctly handle
1522 filenames containing spaces.) In case latexmk's quoting does not work
1523 correctly on your system, you can turn it off -- see the documentation
1524 for the variable $quote_filenames.
1525
1526 The distinction between %B and %R needs a bit of care, since they are
1527 often the same, but not always. For example on a simple document, the
1528 basename of a bibtex run is the same as for the texfile. But in a doc‐
1529 ument with several bibliographies, the bibliography files will have a
1530 variety of names. Since bibtex is invoked with the basename of the
1531 bibliography file, the setting for the bibtex command should therefore
1532 be
1533
1534 $bibtex = 'bibtex %O %B';
1535
1536 Generally, you should use %B rather than %R. Similarly for most pur‐
1537 poses, the name %T of the primary texfile is not a useful placeholder.
1538
1539 See the default values in the section "List of configuration variables
1540 usable in initialization files" for what is normally the most appropri‐
1541 ate usage.
1542
1543 If you omit to supply any placeholders whatever in the specification of
1544 a command, latexmk will supply what its author thinks are appropriate
1545 defaults. This gives compatibility with configuration files for previ‐
1546 ous versions of latexmk, which didn't use placeholders.
1547
1548 "Detaching" a command: Normally when latexmk runs a command, it waits
1549 for the command to run to completion. This is appropriate for commands
1550 like latex, of course. But for previewers, the command should normally
1551 run detached, so that latexmk gets the previewer running and then
1552 returns to its next task (or exits if there is nothing else to do). To
1553 achieve this effect of detaching a command, you need to precede the
1554 command name with "start ", as in
1555
1556 $dvi_previewer = 'start xdvi %O %S';
1557
1558 This will be translated to whatever is appropriate for your operating
1559 system.
1560
1561 Notes: (1) In some circumstances, latexmk will always run a command
1562 detached. This is the case for a previewer in preview continuous mode,
1563 since otherwise previewing continuously makes no sense. (2) This pre‐
1564 cludes the possibility of running a command named start. (3) If the
1565 word start occurs more than once at the beginning of the command
1566 string, that is equivalent to having just one. (4) Under cygwin, some
1567 complications happen, since cygwin amounts to a complicated merging of
1568 UNIX and MS-Windows. See the source code for how I've handled the
1569 problem.
1570
1571 Command names containing spaces: Under MS-Windows it is common that the
1572 name of a command includes spaces, since software is often installed in
1573 a subdirectory of "C:\Program Files". Such command names should be
1574 enclosed in double quotes, as in
1575
1576 $lpr_pdf = '"c:/Program Files/Ghostgum/gsview/gsview32.exe" /p
1577 %S';
1578 $pdf_previewer = 'start "c:/Program Files/SumatraPDF/Suma‐
1579 traPDF.exe" %O %S';
1580 $pdf_previewer = 'start "c:/Program Files/SumatraPDF (x86)/Suma‐
1581 traPDF.exe" %O %S';
1582
1583
1584 (Note about the above example: Under MS-Windows forward slashes are
1585 equivalent to backslashes in a filename under almost all circumstances,
1586 provided that the filename is inside double quotes. It is easier to
1587 use forward slashes in examples like the one above, since then one does
1588 not have to worry about the rules for dealing with forward slashes in
1589 strings in the Perl language.)
1590
1591 Command names under Cygwin: If latexmk is executed by Cygwin's Perl,
1592 be particularly certain that pathnames in commands have forward slashes
1593 not the usual backslashes for the separator of pathname components.
1594 See the above examples. Backslashes often get misinterpreted by the
1595 Unix shell used by Cygwin's Perl to execute external commands. Forward
1596 slashes don't suffer from this problem, and (when quoted, as above) are
1597 equally acceptable to MS-Windows.
1598
1599 Using MS-Windows file associations: A useful trick under modern ver‐
1600 sions of MS-Windows (e.g., WinXP) is to use just the command 'start' by
1601 itself:
1602
1603 $dvi_previewer = 'start %S';
1604
1605 Under MS-Windows, this will cause to be run whatever program the system
1606 has associated with dvi files. (The same applies for a postscript
1607 viewer and a pdf viewer.) But note that this trick is not always suit‐
1608 able for the pdf previwer, if your system has acroread for the default
1609 pdf viewer. As explained elsewhere, acroread under MS-Windows does not
1610 work well with latex and latexmk, because acroread locks the pdf file.
1611
1612 Not using a certain command: If a command is not to be run, the command
1613 name NONE is used, as in
1614
1615 $lpr = 'NONE lpr';
1616
1617 This typically is used when an appropriate command does not exist on
1618 your system. The string after the "NONE" is effectively a comment.
1619
1620 Options to commands: Setting the name of a command can be used not only
1621 for changing the name of the command called, but also to add options to
1622 command. Suppose you want latexmk to use latex with source specials
1623 enabled. Then you might use the following line in an initialization
1624 file:
1625
1626 $latex = 'latex --src-specials %O %S';
1627
1628 Running a subroutine instead of an external command: Use a specifica‐
1629 tion starting with "internal", as in
1630
1631 $latex = 'internal mylatex %O %S';
1632 sub mylatex {
1633 my @args = @_;
1634 # Possible preprocessing here
1635 return system 'latex', @args;
1636 }
1637
1638 For some of the more exotic possibilities that then become available,
1639 see the section "ADVANCED CONFIGURATION: Some extra resources and
1640 advanced tricks". Also see some of the examples in the directory exam‐
1641 ple_rcfiles in the latexmk distribution.
1642
1643 Advanced tricks: Normally one specifies a single command for the com‐
1644 mands invoked by latexmk. Naturally, if there is some complicated
1645 additional processing you need to do in your special situation, you can
1646 write a script (or batch file) to do the processing, and then configure
1647 latexmk to use your script in place of the standard program.
1648
1649 You can also use a Perl subroutine instead of a script -- see above.
1650 This is generally the most flexible and portable solution.
1651
1652 It is also possible to configure latexmk to run multiple commands. For
1653 example, if when running pdflatex to generate a pdf file from a tex
1654 file you need to run another program after pdflatex to perform some
1655 extra processing, you could do something like:
1656
1657 $pdflatex = 'pdflatex --shell-escape %O %S; pst2pdf_for_latexmk
1658 %B';
1659
1660 This definition assumes you are using a UNIX-like system (which
1661 includes Linux and OS-X), so that the two commands to be run are sepa‐
1662 rated by the semicolon in the middle of the string.
1663
1664 If you are using MS-Windows, you would replace the above line by
1665
1666 $pdflatex = 'cmd /c pdflatex --shell-escape %O %S'
1667 . '&& pst2pdf_for_latexmk %B';
1668
1669 Here, the UNIX command separator ; is replaced by &&. In addition,
1670 there is a problem that some versions of Perl on MS-Windows do not obey
1671 the command separator; this problem is overcome by explicitly invoking
1672 the MS-Windows command-line processor cmd.exe.
1673
1674
1676 In this section are specified the variables whose values can be
1677 adjusted to configure latexmk. (See the earlier section "Configura‐
1678 tion/Initialization (rc) Files" for the files where the configurations
1679 are done.)
1680
1681 Default values are indicated in brackets. Note that for variables that
1682 are boolean in character, concerning whether latexmk does or does not
1683 behave in a certain way, a non-zero value, normally 1, indicates true,
1684 i.e., the behavior occurs, while a zero value indicates a false value,
1685 i.e., the behavior does not occur.
1686
1687
1688 $allow_switch [1]
1689
1690 This controls what happens when the output extension of latex,
1691 pdflatex, lualatex or xelatex differs from what is expected.
1692 (The possible extensions are .dvi, .pdf, .xdv.) This can happen
1693 with the use of the \pdfoutput macro in a document compiled
1694 under latex or pdflatex, or with the use of the \outputmode
1695 macro under lualatex. It can also happen with certain kinds of
1696 incorrect configuration.
1697
1698 In such a case, latexmk can appropriately adjust its network of
1699 rules. The adjustment is made if $allow_switch is on, and if no
1700 request for a dvi or ps file has been made.
1701
1702 See the section ALLOWING FOR CHANGE OF OUTPUT EXTENSION.
1703
1704
1705 $always_view_file_via_temporary [0]
1706 Whether .ps and .pdf files are initially to be made in a tempo‐
1707 rary directory and then moved to the final location. (This
1708 applies to dvips, dvipdf, and ps2pdf operations, and the filter‐
1709 ing operators on .dvi and .ps files. It does not apply to
1710 pdflatex, unfortunately, since pdflatex provides no way of spec‐
1711 ifying a chosen name for the output file.)
1712
1713 This use of a temporary file solves a problem that the making of
1714 these files can occupy a substantial time. If a viewer (notably
1715 gv) sees that the file has changed, it may read the new file
1716 before the program writing the file has not yet finished its
1717 work, which can cause havoc.
1718
1719 See the $pvc_view_file_via_temporary variable for a setting that
1720 applies only if preview-continuous mode (-pvc option) is used.
1721 See $tmpdir for the setting of the directory where the temporary
1722 file is created.
1723
1724
1725 $analyze_input_log_always [1]
1726
1727 After a run of latex (etc), always analyze .log for input files
1728 in the <...> and (...) constructions. Otherwise, only do the
1729 analysis when fls file doesn't exist or is out of date.
1730
1731 Under normal circumstances, the data in the fls file is reli‐
1732 able, and the test of the log file gets lots of false positives;
1733 usually $analyze_input_log_always is best set to zero. But the
1734 test of the log file is needed at least in the following situa‐
1735 tion: When a user needs to persuade latexmk that a certain file
1736 is a source file, and latexmk doesn't otherwise find it. Then
1737 the user can write code that causes a line with (...) to be
1738 written to log file. One important case is for lualatex, which
1739 doesn't always generate lines in the .fls file for input lua
1740 files. (The situation with lualatex is HIGHLY version depen‐
1741 dent, e.g., there was a big change between TeXLive 2016 and
1742 TeXLive 2017.)
1743
1744 To keep backward compatibility with older versions of latexmk,
1745 the default is to set $analyze_input_log_always to 1.
1746
1747
1748 $auto_rc_use [1]
1749 Whether to automatically read the standard initialization (rc)
1750 files, which are the system RC file, the user's RC file, and the
1751 RC file in the current directory. The command line option -norc
1752 can be used to turn this setting off. Each RC file could also
1753 turn this setting off, i.e., it could set $auto_rc_use to zero
1754 to prevent automatic reading of the later RC files.
1755
1756 This variable does not affect the reading of RC files specified
1757 on the command line by the -r option.
1758
1759 $aux_dir [""]
1760 The directory in which auxiliary files (aux, log, etc) are to be
1761 written by a run of (pdf)latex. If this variable is not set,
1762 but $out_dir is set, then $aux_dir is set to $out_dir, which is
1763 the directory to which general output files are to be written.
1764
1765 Important note: The effect of $aux_dir, if different from
1766 $out_dir, is achieved by giving (pdf)latex the -aux-directory.
1767 Currently (Dec. 2011 and later) this only works on the MiKTeX
1768 version of (pdf)latex.
1769
1770 See also the documentation of $out_dir for some complications on
1771 what directory names are suitable.
1772
1773 If you also use the -cd option, and $out_dir (or $aux_dir) con‐
1774 tains a relative path, then the path is interpreted relative to
1775 the document directory.
1776
1777 $banner [0]
1778 If nonzero, the banner message is printed across each page when
1779 converting the dvi file to postscript. Without modifying the
1780 variable $banner_message, this is equivalent to specifying the
1781 -d option.
1782
1783 Note that if $banner is nonzero, the $postscript_mode is assumed
1784 and the postscript file is always generated, even if it is newer
1785 than the dvi file.
1786
1787 $banner_intensity [0.95]
1788 Equivalent to the -bi option, this is a decimal number between 0
1789 and 1 that specifies how dark to print the banner message. 0 is
1790 black, 1 is white. The default is just right if your toner car‐
1791 tridge isn't running too low.
1792
1793 $banner_message ["DRAFT"]
1794 The banner message to print across each page when converting the
1795 dvi file to postscript. This is equivalent to the -bm option.
1796
1797 $banner_scale [220.0]
1798 A decimal number that specifies how large the banner message
1799 will be printed. Experimentation is necessary to get the right
1800 scale for your message, as a rule of thumb the scale should be
1801 about equal to 1100 divided by the number of characters in the
1802 message. The Default is just right for 5 character messages.
1803 This is equivalent to the -bs option.
1804
1805 @BIBINPUTS
1806 This is an array variable, now mostly obsolete, that specifies
1807 directories where latexmk should look for .bib files. By
1808 default it is set from the BIBINPUTS environment variable of the
1809 operating system. If that environment variable is not set, a
1810 single element list consisting of the current directory is set.
1811 The format of the directory names depends on your operating sys‐
1812 tem, of course. Examples for setting this variable are:
1813
1814 @BIBINPUTS = ( ".", "C:\\bibfiles" );
1815 @BIBINPUTS = ( ".", "\\server\bibfiles" );
1816 @BIBINPUTS = ( ".", "C:/bibfiles" );
1817 @BIBINPUTS = ( ".", "//server/bibfiles" );
1818 @BIBINPUTS = ( ".", "/usr/local/texmf/bibtex/bib" );
1819
1820 Note that under MS Windows, either a forward slash "/" or a
1821 backward slash "\" can be used to separate pathname components,
1822 so the first two and the second two examples are equivalent.
1823 Each backward slash should be doubled to avoid running afoul of
1824 Perl's rules for writing strings.
1825
1826 Important note: This variable is now mostly obsolete in the cur‐
1827 rent version of latexmk, since it has a better method of search‐
1828 ing for files using the kpsewhich command. However, if your
1829 system is an unusual one without the kpsewhich command, you may
1830 need to set the variable @BIBINPUTS.
1831
1832 $biber ["biber %O %S"]
1833 The biber processing program.
1834
1835 $biber_silent_switch ["--onlylog"]
1836 Switch(es) for the biber processing program when silent mode is
1837 on.
1838
1839 $bibtex ["bibtex %O %S"]
1840 The BibTeX processing program.
1841
1842 $bibtex_fudge [1]
1843 When using bibtex, whether to take special action to allow bib‐
1844 tex to work when $out_dir or $aux_dir is specified. In May
1845 2018, there was planned an update to bibtex to correct a bug,
1846 after that update, the special action will no longer be
1847 required.
1848
1849 $bibtex_silent_switch ["-terse"]
1850 Switch(es) for the BibTeX processing program when silent mode is
1851 on.
1852
1853 $bibtex_use [1]
1854 Under what conditions to run bibtex or biber. When latexmk dis‐
1855 covers from the log file that one (or more) bibtex/biber-gener‐
1856 ated bibliographies are used, it can run bibtex or biber when‐
1857 ever it appears necessary to regenerate the bbl file(s) from
1858 their source bib database file(s). But sometimes, the bib
1859 file(s) are not available (e.g., for a document obtained from an
1860 external archive), but the bbl files are provided. In that case
1861 use of bibtex or biber will result in incorrect overwriting of
1862 the precious bbl files. The variable $bibtex_use controls
1863 whether this happens, and also controls whether or not .bbl
1864 files are deleted in a cleanup operation.
1865
1866 The possible values of $bibtex_use are:
1867 0: never use BibTeX or biber; never delete .bbl files in a
1868 cleanup.
1869 1: only use bibtex or biber if the bib files exist; never
1870 delete .bbl files in a cleanup.
1871 1.5: only use bibtex or biber if the bib files exist; condi‐
1872 tionally delete .bbl files in a cleanup (i.e., delete them only
1873 when the bib files all exist).
1874 2: run bibtex or biber whenever it appears necessary to update
1875 the bbl files, without testing for the existence of the bib
1876 files; always delete .bbl files in a cleanup.
1877
1878 Note that the value 1.5 does not work properly if the document
1879 uses biber instead of bibtex. (There's a long story why not.)
1880
1881
1882 $cleanup_includes_cusdep_generated [0]
1883 If nonzero, specifies that cleanup also deletes files that are
1884 generated by custom dependencies. (When doing a clean up, e.g.,
1885 by use of the -C option, custom dependencies are those listed in
1886 the .fdb_latexmk file from a previous run.)
1887
1888 $cleanup_includes_generated [0]
1889 If nonzero, specifies that cleanup also deletes files that are
1890 detected in the fls file (or failing that, in log file) as being
1891 generated. It will also include files made from these first
1892 generation generated files.
1893
1894 This operation is somewhat dangerous, and can have unintended
1895 consequences, since the files to be deleted are determined from
1896 a file created by (pdf)latex, which can contain erroneous infor‐
1897 mation. Therefore this variable is turned off by default, and
1898 then files to be deleted are restricted to those explictly spec‐
1899 ified by patterns configured in the variables clean_ext,
1900 clean_full_ext, and @generated_exts, together with those very
1901 standard cases that are hardwired into latexmk (e.g., .log
1902 files).
1903
1904 $cleanup_mode [0]
1905 If nonzero, specifies cleanup mode: 1 for full cleanup, 2 for
1906 cleanup except for .dvi, .ps and .pdf files, 3 for cleanup
1907 except for dep and aux files. (There is also extra cleaning as
1908 specified by the $clean_ext, $clean_full_ext and @generated_exts
1909 variables.)
1910
1911 This variable is equivalent to specifying one of the -c or -C
1912 options. But there should be no need to set this variable from
1913 an RC file.
1914
1915 $clean_ext [""]
1916 Extra extensions of files for latexmk to remove when any of the
1917 clean-up options (-c or -C) is selected. The value of this
1918 variable is a string containing the extensions separated by spa‐
1919 ces.
1920
1921 It is also possible to specify a more general pattern of file to
1922 be deleted, by using the place holder %R, as in commands, and it
1923 is also possible to use wildcards. Thus setting
1924
1925 $clean_ext = "out %R-blx.bib %R-figures*.log pythontex-
1926 files-%R/*";
1927
1928 in an initialization file will imply that when a clean-up opera‐
1929 tion is specified, not only is the standard set of files
1930 deleted, but also files of the form FOO.out, FOO-blx.bib, %R-
1931 figures*.log, and pythontex-files-FOO/*, where FOO stands for
1932 the basename of the file being processed (as in FOO.tex).
1933
1934 The files to be deleted are relative to the directory specified
1935 by $aux_dir. (Note that if $out_dir but not $aux_dir is set,
1936 then in its initialization, latexmk sets $aux_dir equal to
1937 $out_dir. A normal situation is therefore that $aux_dir equals
1938 $out_dir, which is the only case supported by TeXLive, unlike
1939 MiKTeX.)
1940
1941 The filenames specfied for a clean-up operation can refer not
1942 only to regular files but also to directories. Directories are
1943 only deleted if they are empty. An example of an application is
1944 to pythontex, which creates files in a particular directory.
1945 You can arrange to remove both the files and the directory by
1946 setting
1947
1948 $clean_ext = "pythontex-files-%R pythontex-files-%R";
1949
1950 See also the variable @generated_exts.
1951
1952 $clean_full_ext [""]
1953 Extra extensions of files for latexmk to remove when the -C
1954 option is selected, i.e., extensions of files to remove when the
1955 .dvi, etc files are to be cleaned-up.
1956
1957 More general patterns are allowed, as for $clean_ext.
1958
1959 The files specified by $clean_full_ext to be deleted are rela‐
1960 tive to the directory specified by $out_dir.
1961
1962
1963 $compiling_cmd [""], $failure_cmd [""], $warning_cmd [""], $success_cmd
1964 [""]
1965
1966 These variables specify commands that are executed at certain
1967 points of compilations during preview-continuous mode. One
1968 motivation for their existance is to allow very useful conve‐
1969 nient visual indications of compilation status even when the
1970 window receiving the screen output of the compilation is hidden.
1971
1972 The commands are executed at the following points: $compil‐
1973 ing_cmd at the start of compilation, $success_cmd at the end of
1974 a completely successful compilation, $failure_cmd at the end of
1975 an unsuccessful compilation, $warning_cmd at the of an otherwise
1976 successful compilation that gives warnings about undefined cita‐
1977 tions or references or about multiply defined references. If any
1978 of above variables is undefined or blank (the default situa‐
1979 tion), then the corresponding command is not executed.
1980
1981 However, when $warning_cmd is not set, then in the case of a
1982 compilation with warnings about references or citations, but
1983 with no other error, one or other of $success_cmd or $fail‐
1984 ure_cmd is used (if it is set) according to the setting of
1985 $warnings_as_errors.
1986
1987 An example of a simple setting of these variables is as follows
1988
1989 $compiling_cmd = "xdotool search --name \"%D\" set_window
1990 --name \"%D compiling\"";
1991 $success_cmd = "xdotool search --name \"%D\" set_window
1992 --name \"%D OK\"";
1993 $warning_cmd = "xdotool search --name \"%D\" ".
1994 "set_window --name \"%D CITE/REF ISSUE\"";
1995 $failure_cmd = "xdotool search --name \"%D\" set_window
1996 --name \"%D FAILURE\"";
1997
1998 These assume that the program xdotool is installed, that the
1999 previewer is using an X-Window system for display, and that the
2000 title of the window contains the name of the displayed file, as
2001 it normally does. When the commands are executed, the place‐
2002 holder string %D is replaced by the name of the destination
2003 file, which is the previewed file. The above commands result in
2004 an appropriate string being appended to the filename in the win‐
2005 dow title: " compiling", " OK", or " FAILURE".
2006
2007 Other placeholders that can be used are %S, %T, and %R, with %S
2008 and %T normally being identical. These can be useful for a com‐
2009 mand changing the title of the edit window. The visual indica‐
2010 tion in a window title can useful, since the user does not have
2011 to keep shifting attention to the (possibly hidden) compilation
2012 window to know the status of the compilation.
2013
2014 More complicated situations can best be handled by defining a
2015 Perl subroutine to invoke the necessary commands, and using the
2016 "internal" keyword in the definitions to get the subroutine to
2017 be invoked. (See the section "Format of Command Specifications"
2018 for how to do this.)
2019
2020 Naturally, the above settings that invoke the xdotool program
2021 are only applicable when the X-Window system is used for the
2022 relevant window(s). For other cases, you will have to find what
2023 software solutions are available.
2024
2025
2026 @cus_dep_list [()]
2027 Custom dependency list -- see section on "Custom Dependencies".
2028
2029 @default_excluded_files [()]
2030 When latexmk is invoked with no files specified on the command
2031 line, then, by default, it will process all files in the current
2032 directory with the extension .tex. (In general, it will process
2033 the files specified in the @default_files variable.)
2034
2035 But sometimes you want to exclude particular files from this
2036 default list. In that case you can specify the excluded files
2037 in the array @default_excluded_files. For example if you wanted
2038 to process all .tex files with the exception of common.tex,
2039 which is a not a standard alone LaTeX file but a file input by
2040 some or all of the others, you could do
2041
2042 @default_files = ("*.tex");
2043
2044 @default_excluded_files = ("common.tex");
2045
2046 If you have a variable or large number of files to be processed,
2047 this method saves you from having to list them in detail in
2048 @default_files and having to update the list every time you
2049 change the set of files to be processed.
2050
2051 Notes: 1. This variable has no effect except when no files are
2052 specified on the latexmk command line. 2. Wildcards are allowed
2053 in @default_excluded_files.
2054
2055 @default_files [("*.tex")]
2056 Default list of files to be processed.
2057
2058 If no filenames are specified on the command line, latexmk pro‐
2059 cesses all tex files specified in the @default_files variable,
2060 which by default is set to all tex files ("*.tex") in the cur‐
2061 rent directory. This is a convenience: just run latexmk and it
2062 will process an appropriate set of files. But sometimes you
2063 want only some of these files to be processed. In this case you
2064 can list the files to be processed by setting @default_files in
2065 an initialization file (e.g., the file "latexmkrc" in the cur‐
2066 rent directory). Then if no files are specified on the command
2067 line then the files you specify by setting @default_files are
2068 processed.
2069
2070 Three examples:
2071
2072 @default_files = ("paper_current");
2073
2074 @default_files = ("paper1", "paper2.tex");
2075
2076 @default_files = ("*.tex", "*.dtx");
2077
2078 Note that more than file may be given, and that the default
2079 extension is ".tex". Wild cards are allowed. The parentheses
2080 are because @default_files is an array variable, i.e., a
2081 sequence of filename specifications is possible.
2082
2083 If you want latexmk to process all .tex files with a few excep‐
2084 tions, see the @default_excluded_files array variable.
2085
2086 $dependents_phony [0]
2087 If a list of dependencies is output, this variable determines
2088 whether to include a phony target for each source file. If you
2089 use the dependents list in a Makefile, the dummy rules work
2090 around errors make gives if you remove header files without
2091 updating the Makefile to match.
2092
2093 $dependents_list [0]
2094 Whether to display a list(s) of dependencies at the end of a
2095 run.
2096
2097 $deps_file ["-"]
2098 Name of file to receive list(s) of dependencies at the end of a
2099 run, to be used if $dependesnt_list is set. If the filename is
2100 "-", then the dependency list is set to stdout (i.e., normally
2101 the screen).
2102
2103 $do_cd [0]
2104 Whether to change working directory to the directory specified
2105 for the main source file before processing it. The default
2106 behavior is not to do this, which is the same as the behavior of
2107 latex and pdflatex programs. This variable is set by the -cd
2108 and -cd- options on latexmk's command line.
2109
2110 $dvi_filter [empty]
2111 The dvi file filter to be run on the newly produced dvi file
2112 before other processing. Equivalent to specifying the -dF
2113 option.
2114
2115 $dvi_mode [See below for default]
2116 If nonzero, generate a dvi version of the document. Equivalent
2117 to the -dvi option.
2118
2119 The variable $dvi_mode defaults to 0, but if no explicit
2120 requests are made for other types of file (postscript, pdf),
2121 then $dvi_mode will be set to 1. In addition, if a request for
2122 a file for which a .dvi file is a prerequisite, then $dvi_mode
2123 will be set to 1.
2124
2125 $dvi_previewer ["start xdvi %O %S" under UNIX]
2126 The command to invoke a dvi-previewer. [Under MS-Windows the
2127 default is "start"; then latexmk arranges to use the MS-Windows
2128 start program, which will cause to be run whatever command the
2129 system has associated with .dvi files.]
2130
2131 Important note: Normally you will want to have a previewer run
2132 detached, so that latexmk doesn't wait for the previewer to ter‐
2133 minate before continuing its work. So normally you should pre‐
2134 fix the command by "start ", which flags to latexmk that it
2135 should do the detaching of the previewer itself (by whatever
2136 method is appropriate to the operating system). But sometimes
2137 letting latexmk do the detaching is not appropriate (for a vari‐
2138 ety of non-trivial reasons), so you should put the "start " bit
2139 in yourself, whenever it is needed.
2140
2141 $dvi_previewer_landscape ["start xdvi %O %S"]
2142 The command to invoke a dvi-previewer in landscape mode. [Under
2143 MS-Windows the default is "start"; then latexmk arranges to use
2144 the MS-Windows start program, which will cause to be run what‐
2145 ever command the system has associated with .dvi files.]
2146
2147 $dvipdf ["dvipdf %O %S %D"]
2148 Command to convert .dvi to .pdf file. A common reconfiguration
2149 is to use the dvipdfm command, which needs its arguments in a
2150 different order:
2151
2152 $dvipdf = "dvipdfm %O -o %D %S";
2153
2154 WARNING: The default dvipdf script generates pdf files with
2155 bitmapped fonts, which do not look good when viewed by acroread.
2156 That script should be modified to give dvips the options "-P
2157 pdf" to ensure that type 1 fonts are used in the pdf file.
2158
2159 $dvipdf_silent_switch ["-q"]
2160 Switch(es) for dvipdf program when silent mode is on.
2161
2162 N.B. The standard dvipdf program runs silently, so adding the
2163 silent switch has no effect, but is actually innocuous. But if
2164 an alternative program is used, e.g., dvipdfmx, then the silent
2165 switch has an effect. The default setting is correct for
2166 dvipdfm and dvipdfmx.
2167
2168 $dvips ["dvips %O -o %D %S"]
2169 The program to used as a filter to convert a .dvi file to a .ps
2170 file. If pdf is going to be generated from pdf, then the value
2171 of the $dvips_pdf_switch variable -- see below -- will be
2172 included in the options substituted for "%O".
2173
2174 $dvips_landscape ["dvips -tlandscape %O -o %D %S"]
2175 The program to used as a filter to convert a .dvi file to a .ps
2176 file in landscape mode.
2177
2178 $dvips_pdf_switch ["-P pdf"]
2179 Switch(es) for dvips program when pdf file is to be generated
2180 from .ps file.
2181
2182 $dvips_silent_switch ["-q"]
2183 Switch(es) for dvips program when silent mode is on.
2184
2185 $dvi_update_command [""]
2186 When the dvi previewer is set to be updated by running a com‐
2187 mand, this is the command that is run. See the information for
2188 the variable $dvi_update_method for further information, and see
2189 information on the variable $pdf_update_method for an example
2190 for the analogous case of a pdf previewer.
2191
2192 $dvi_update_method [2 under UNIX, 1 under MS-Windows]
2193 How the dvi viewer updates its display when the dvi file has
2194 changed. The values here apply equally to the
2195 $pdf_update_method and to the $ps_update_method variables.
2196 0 => update is automatic,
2197 1=> manual update by user, which may only mean a mouse click
2198 on the viewer's window or may mean a more serious action.
2199 2 => Send the signal, whose number is in the variable
2200 $dvi_update_signal. The default value under UNIX is suitable
2201 for xdvi.
2202 3 => Viewer cannot do an update, because it locks the file.
2203 (As with acroread under MS-Windows.)
2204 4 => run a command to do the update. The command is speci‐
2205 fied by the variable $dvi_update_command.
2206
2207 See information on the variable $pdf_update_method for an exam‐
2208 ple of updating by command.
2209
2210 $dvi_update_signal [Under UNIX: SIGUSR1, which is a system-dependent
2211 value]
2212 The number of the signal that is sent to the dvi viewer when it
2213 is updated by sending a signal -- see the information on the
2214 variable $dvi_update_method. The default value is the one
2215 appropriate for xdvi on a UNIX system.
2216
2217 $failure_cmd [undefined]
2218 See the documentation for $compiling_cmd.
2219
2220 $fdb_ext ["fdb_latexmk"]
2221 The extension of the file which latexmk generates to contain a
2222 database of information on source files. You will not normally
2223 need to change this.
2224
2225 $filetime_causality_threshold [5]; $filetime_offset_report_threshold
2226 [30]. (Units of seconds.)
2227
2228 These variables control how latexmk deals with the following
2229 issue, which can affect the use of files that are on a remote
2230 filesystem (network share) instead of being on a file system
2231 local to the computer running latexmk. Almost users will not
2232 have to worry about these settings, and can ignore the following
2233 explanation.
2234
2235 In almost all situations, latexmk does not need to use the time
2236 stamps of the files it works with. However, there are a couple
2237 of situations when it needs to know whether a certain file was
2238 created in the current run of a program (e.g., (pdf)latex) or is
2239 a leftover file from a previous run. It does this by comparing
2240 the modification time of the file with the system time just
2241 before the program was started. If the modification time is ear‐
2242 lier than when the program was started, the file is a leftover
2243 file, which latexmk treats as if it were not created. If the
2244 filetime is at least the program start time, then it can be
2245 assumed that the file was created in the current run.
2246
2247 Unfortunately, this test can fail if the file is on a remote
2248 system, since its system time is not necessarily synchronized
2249 with that of the local system; the timestamps on the remote
2250 files are set by the remote system, not the local system. Gen‐
2251 erally, modern operating systems regularly synchronize their
2252 time with a server, so the non-synchronization is mostly small
2253 (a second or so, or a few seconds). But even a small difference
2254 can mess up latexmk's test.
2255
2256 Latexmk measures the time difference between the time on the two
2257 systems and compensates for this. But the measurement (in a
2258 system-independent way) is only accurate to a second or two. So
2259 latexmk allows for a threshold on the difference between file
2260 and system time before it concludes that a file is a leftover
2261 file from a previous run. The configuration variable $file‐
2262 time_causality_theshhold, which in units of seconds, specifies
2263 this threshold. Luckily high precision is not needed. The pre‐
2264 vious run is normally the previous run in a human run-edit-run
2265 cycle, and is at least many seconds back. A few seconds is
2266 therefore appropriate for the threshold, $filetime_causal‐
2267 ity_theshhold; it should be non-negative always, and should be
2268 bigger than 2 if a remote filesystem or network share is used.
2269
2270 If the difference in system times on the two systems is large,
2271 it normally indicates that at least one of the systems is mis‐
2272 configured. The variable $filetime_offset_report_threshold
2273 specifies the smallest size of the difference (or offset) in
2274 seconds between the times of the local and remote system beyond
2275 which the offset is reported. This is reported at the point in
2276 the latexmk's progress that it measures the offset. The report
2277 is made if silent mode is used and diagnostic mode is not on.
2278
2279
2280 $force_mode [0]
2281 If nonzero, continue processing past minor latex errors includ‐
2282 ing unrecognized cross references. Equivalent to specifying the
2283 -f option.
2284
2285 @generated_exts [( aux , bbl , idx , ind , lof , lot , out , toc ,
2286 $fdb_ext )]
2287 This contains a list of extensions for files that are generated
2288 during a LaTeX run and that are read in by LaTeX in later runs,
2289 either directly or indirectly.
2290
2291 This list specifies files known to be generated by latex (and
2292 pdflatex, etc). It is used in two ways: (a) The specified files
2293 are deleted in a cleanup operation (with the -c, -C, -CA, -g and
2294 -gg options), and (b) It affects the determination of whether a
2295 rerun of (pdf)LaTeX is needed after a run that gives an error.
2296
2297 (Concerning item (b): Normally, a change of a source file during
2298 a run should provoke a rerun. This includes a file generated by
2299 LaTeX, e.g., an aux file, that is read in on subsequent runs.
2300 But after a run that results in an error, a new run should not
2301 occur until the user has made a change in the files. But the
2302 user may have corrected an error in a source .tex file during
2303 the run. So latexmk needs to distinguish user-generated and
2304 automatically generated files; it determines the automatically
2305 generated files as those with extensions in the list in @gener‐
2306 ated_exts.)
2307
2308 A convenient way to add an extra extension to the list, without
2309 losing the already defined ones is to use a push command in the
2310 line in an RC file. E.g.,
2311
2312 push @generated_exts, "end";
2313
2314 adds the extension "end" to the list of predefined generated
2315 extensions. (This extension is used by the RevTeX package, for
2316 example.)
2317
2318 $go_mode [0]
2319 If nonzero, process files regardless of timestamps, and is then
2320 equivalent to the -g option.
2321
2322 %hash_calc_ignore_pattern
2323 !!!This variable is for experts only!!!
2324
2325 The general rule latexmk uses for determining when an extra run
2326 of some program is needed is that one of the source files has
2327 changed. But consider for example a latex package that causes
2328 an encapsulated postscript file (an "eps" file) to be made that
2329 is to be read in on the next run. The file contains a comment
2330 line giving its creation date and time. On the next run the
2331 time changes, latex sees that the eps file has changed, and
2332 therefore reruns latex. This causes an infinite loop, that is
2333 only terminated because latexmk has a limit on the number of
2334 runs to guard against pathological situations.
2335
2336 But the changing line has no real effect, since it is a comment.
2337 You can instruct latex to ignore the offending line as follows:
2338
2339 $hash_calc_ignore_pattern{'eps'} = '^%%CreationDate: ';
2340
2341 This creates a rule for files with extension .eps about lines to
2342 ignore. The left-hand side is a Perl idiom for setting an item
2343 in a hash. Note that the file extension is specified without a
2344 period. The value, on the right-hand side, is a string contain‐
2345 ing a regular expresssion. (See documentation on Perl for how
2346 they are to be specified in general.) This particular regular
2347 expression specifies that lines beginning with "%%CreationDate:
2348 " are to be ignored in deciding whether a file of the given
2349 extension .eps has changed.
2350
2351 There is only one regular expression available for each exten‐
2352 sion. If you need more one pattern to specify lines to ignore,
2353 then you need to combine the patterns into a single regular
2354 expression. The simplest method is separate the different sim‐
2355 ple patterns by a vertical bar character (indicating "alterna‐
2356 tion" in the jargon of regular expressions). For example,
2357
2358 $hash_calc_ignore_pattern{'eps'} = '^%%CreationDate:
2359 |^%%Title: ';
2360
2361 causes lines starting with either "^%%CreationDate: " or
2362 "^%%Title: " to be ignored.
2363
2364 It may happen that a pattern to be ignored is specified in, for
2365 example, in a system or user initialization file, and you wish
2366 to remove this in a file that is read later. To do this, you
2367 use Perl's delete function, e.g.,
2368
2369 delete $hash_calc_ignore_pattern{'eps'};
2370
2371
2372 $jobname [""]
2373
2374 This specifies the jobname, i.e., the basename that is used for
2375 generated files (.aux, .log, .dvi, .ps, .pdf, etc). If this
2376 variable is a null string, then the basename is the basename of
2377 the main tex file. (At present, the string in $jobname should
2378 not contain spaces.)
2379
2380 The placeholder '%A' is permitted. This will be substituted by
2381 the basename of the TeX file. The primary purpose is when a
2382 variety of tex files are to be processed, and you want to use a
2383 different jobname for each but one that is distinct for each.
2384 Thus if you wanted to compare compilations of a set of files on
2385 different operating systems, with distinct filenames for all the
2386 cases, you could set
2387
2388 $jobname = "%A-$^O";
2389
2390 in an initialization file. (Here $^O is a variable provided by
2391 perl that contains perl's name for the operating system.)
2392
2393 Suppose you had .tex files test1.tex and test2.tex. Then when
2394 you run
2395
2396 latexmk -pdf *.tex
2397
2398 both files will be compiled. The .aux, .log, and .pdf files
2399 will have basenames test1-MSWin32 ante test2-MSWin32 on a MS-
2400 Windows system, test1-darwin and test2-darwin on an OS-X system,
2401 and a variety of similar cases on linux systems.
2402
2403
2404 $kpsewhich ["kpsewhich %S"]
2405 The program called to locate a source file when the name alone
2406 is not sufficient. Most filenames used by latexmk have suffi‐
2407 cient path information to be found directly. But sometimes,
2408 notably when a .bib or a .bst file is found from the log file of
2409 a bibtex or biber run, only the base name of the file is known,
2410 but not its path. The program specified by $kpsewhich is used to
2411 find it.
2412
2413 (For advanced users: Because of the different way in which
2414 latexmk uses the command specified in $kpsewhich, some of the
2415 possibilities listed in the FORMAT OF COMMAND SPECIFICATIONS do
2416 not apply. The internal and start keywords are not available. A
2417 simple command specification with possible options and then "%S"
2418 is all that is guaranteed to work. Note that for other com‐
2419 mands, "%S" is substituted by a single source file. In contrast,
2420 for $kpsewhich, "%S" may be substituted by a long list of space-
2421 separated filenames, each of which is quoted. The result on
2422 STDOUT of running the command is then piped to latexmk.)
2423
2424 See also the @BIBINPUTS variable for another way that latexmk
2425 also uses to try to locate files; it applies only in the case of
2426 .bib files.
2427
2428 $kpsewhich_show [0]
2429 Whether to show diagnostics about invocations of kpsewhich: the
2430 command line use to invoke it and the results. These diagnos‐
2431 tics are shown if $kpsewhich_show is non-zero or if diagnostics
2432 mode is on. (But in the second case, lots of other diagnostics
2433 are also shown.) Without these diagnostics there is nothing
2434 visible in latexmk's screen output about invocations of kpse‐
2435 which.
2436
2437 $landscape_mode [0]
2438 If nonzero, run in landscape mode, using the landscape mode pre‐
2439 viewers and dvi to postscript converters. Equivalent to the -l
2440 option. Normally not needed with current previewers.
2441
2442 $latex ["latex %O %S"]
2443 Specifies the command line for the LaTeX processing program.
2444 Note that as with other programs, you can use this variable not
2445 just to change the name of the program used, but also specify
2446 options to the program. E.g.,
2447
2448 $latex = "latex --src-specials %O %S";
2449
2450 To do a coordinated setting of all of $latex, $pdflatex, $luala‐
2451 tex, and $xelatex, see the section "Advanced Configuration".
2452
2453
2454 %latex_input_extensions
2455 This variable specifies the extensions tried by latexmk when it
2456 finds that a LaTeX run resulted in an error that a file has not
2457 been found, and the file is given without an extension. This
2458 typically happens when LaTeX commands of the form \input{file}
2459 or \includegraphics{figure}, when the relevant source file does
2460 not exist.
2461
2462 In this situation, latexmk searches for custom dependencies to
2463 make the missing file(s), but restricts it to the extensions
2464 specified by the variable %latex_input_extensions. The default
2465 extensions are 'tex' and 'eps'.
2466
2467 (For Perl experts: %latex_input_extensions is a hash whose keys
2468 are the extensions. The values are irrelevant.) Two subrou‐
2469 tines are provided for manipulating this and the related vari‐
2470 able %pdflatex_input_extensions, add_input_ext and
2471 remove_input_ext. They are used as in the following examples
2472 are possible lines in an initialization file:
2473
2474 remove_input_ext( 'latex', 'tex' );
2475
2476 removes the extension 'tex' from latex_input_extensions
2477
2478 add_input_ext( 'latex', 'asdf' );
2479
2480 add the extension 'asdf to latex_input_extensions. (Naturally
2481 with such an extension, you should have made an appropriate cus‐
2482 tom dependency for latexmk, and should also have done the appro‐
2483 priate programming in the LaTeX source file to enable the file
2484 to be read. The standard extensions are handled by LaTeX and
2485 its graphics/graphicx packages.)
2486
2487 $latex_silent_switch ["-interaction=batchmode"]
2488 Switch(es) for the LaTeX processing program when silent mode is
2489 on.
2490
2491 If you use MikTeX, you may prefer the results if you configure
2492 the options to include -c-style-errors, e.g., by the following
2493 line in an initialization file
2494
2495 $latex_silent_switch = "-interaction=batchmode -c-style-
2496 errors";
2497
2498
2499 $lpr ["lpr %O %S" under UNIX/Linux, "NONE lpr" under MS-Windows]
2500 The command to print postscript files.
2501
2502 Under MS-Windows (unlike UNIX/Linux), there is no standard pro‐
2503 gram for printing files. But there are ways you can do it. For
2504 example, if you have gsview installed, you could use it with the
2505 option "/p":
2506
2507 $lpr = '"c:/Program Files/Ghostgum/gsview/gsview32.exe" /p';
2508
2509 If gsview is installed in a different directory, you will need
2510 to make the appropriate change. Note the combination of single
2511 and double quotes around the name. The single quotes specify
2512 that this is a string to be assigned to the configuration vari‐
2513 able $lpr. The double quotes are part of the string passed to
2514 the operating system to get the command obeyed; this is neces‐
2515 sary because one part of the command name ("Program Files") con‐
2516 tains a space which would otherwise be misinterpreted.
2517
2518 $lpr_dvi ["NONE lpr_dvi"]
2519 The printing program to print dvi files.
2520
2521 $lpr_pdf ["NONE lpr_pdf"]
2522 The printing program to print pdf files.
2523
2524 Under MS-Windows you could set this to use gsview, if it is
2525 installed, e.g.,
2526
2527 $lpr = '"c:/Program Files/Ghostgum/gsview/gsview32.exe" /p';
2528
2529 If gsview is installed in a different directory, you will need
2530 to make the appropriate change. Note the double quotes around
2531 the name: this is necessary because one part of the command name
2532 ("Program Files") contains a space which would otherwise be mis‐
2533 interpreted.
2534
2535 $lualatex ["lualatex %O %S"]
2536 Specifies the command line for the LaTeX processing program that
2537 is to be used when the lualatex program is called for (e.g., by
2538 the option -lualatex.
2539
2540 To do a coordinated setting of all of $latex, $pdflatex, $luala‐
2541 tex, and $xelatex, see the section "Advanced Configuration".
2542
2543
2544 %lualatex_input_extensions
2545 This variable specifies the extensions tried by latexmk when it
2546 finds that a lualatex run resulted in an error that a file has
2547 not been found, and the file is given without an extension.
2548 This typically happens when LaTeX commands of the form
2549 \input{file} or \includegraphics{figure}, when the relevant
2550 source file does not exist.
2551
2552 In this situation, latexmk searches for custom dependencies to
2553 make the missing file(s), but restricts it to the extensions
2554 specified by the variable %pdflatex_input_extensions. The
2555 default extensions are 'tex', 'pdf', 'jpg, and 'png'.
2556
2557 See details of the %latex_input_extensions for other information
2558 that equally applies to %lualatex_input_extensions.
2559
2560 $lualatex_silent_switch ["-interaction=batchmode"]
2561 Switch(es) for the lualatex program (specified in the variable
2562 $lualatex) when silent mode is on.
2563
2564 See details of the $latex_silent_switch for other information
2565 that equally applies to $lualatex_silent_switch.
2566
2567 $make ["make"]
2568 The make processing program.
2569
2570 $makeindex ["makeindex %O -o %D %S"]
2571 The index processing program.
2572
2573 $makeindex_silent_switch ["-q"]
2574 Switch(es) for the index processing program when silent mode is
2575 on.
2576
2577 $max_repeat [5]
2578 The maximum number of times latexmk will run latex/pdflatex
2579 before deciding that there may be an infinite loop and that it
2580 needs to bail out, rather than rerunning latex/pdflatex again to
2581 resolve cross-references, etc. The default value covers all
2582 normal cases.
2583
2584 (Note that the "etc" covers a lot of cases where one run of
2585 latex/pdflatex generates files to be read in on a later run.)
2586
2587 $MSWin_back_slash [1]
2588 This configuration variable only has an effect when latexmk is
2589 running under MS-Windows. It determines whether, when a command
2590 is executed under MS-Windows, there should be substituted "\"
2591 for the separator character between components of a directory
2592 name. Internally, latexmk uses "/" for the directory separator
2593 character, which is the character used by Unix-like systems.
2594
2595 For many programs under MS-Windows, both "\" and "/" are accept‐
2596 able as the directory separator character. But some programs
2597 only accept "\" on the command line. So for safety latexmk
2598 makes a translation, by default. It is conceivable that under
2599 certain situations this is undesirable, so the configuration can
2600 be changed. (A possible example might be when some of the soft‐
2601 ware is implemented using Cygwin, which provides a Unix-like
2602 environment inside MS-Windows.)
2603
2604 $new_viewer_always [0]
2605 This variable applies to latexmk only in continuous-preview
2606 mode. If $new_viewer_always is 0, latexmk will check for a pre‐
2607 viously running previewer on the same file, and if one is run‐
2608 ning will not start a new one. If $new_viewer_always is non-
2609 zero, this check will be skipped, and latexmk will behave as if
2610 no viewer is running.
2611
2612 $out_dir [""]
2613 If non-blank, this variable specifies the directory in which
2614 output files are to be written by a run of (pdf)latex. See also
2615 the variable $aux_dir.
2616
2617 The effect of this variable (when non-blank) is achieved by
2618 using the -output-directory option of (pdf)latex. This exists
2619 in the usual current (Dec. 2011 and later) implementations of
2620 TeX, i.e., MiKTeX and TeXLive. But it may not be present in
2621 other versions.
2622
2623 If you also use the -cd option, and $out_dir (or $aux_dir) con‐
2624 tains a relative path, then the path is interpreted relative to
2625 the document directory.
2626
2627 Commonly, the directory specified for output files is a subdi‐
2628 rectory of the current working directory. However, if you spec‐
2629 ify some other directory, e.g., "/tmp/foo" or "../output", be
2630 aware that this could cause problems, e.g., with makeindex or
2631 bibtex. This is because modern versions of these programs, by
2632 default, will refuse to work when they find that they are asked
2633 to write to a file in a directory that appears not to be the
2634 current working directory or one of its subdirectories. This is
2635 part of security measures by the whole TeX system that try to
2636 prevent malicious or errant TeX documents from incorrectly mess‐
2637 ing with a user's files. If for $out_dir or $aux_dir you really
2638 do need to specify an absolute pathname (e.g., "/tmp/foo") or a
2639 path (e.g., "../output") that includes a higher-level directory,
2640 and you need to use makeindex or bibtex, then you need to dis‐
2641 able the security measures (and assume any risks). One way of
2642 doing this is to temporarily set an operating system environment
2643 variable openout_any to "a" (as in "all"), to override the
2644 default "paranoid" setting.
2645
2646 $pdf_mode [0]
2647 If zero, do NOT generate a pdf version of the document. If
2648 equal to 1, generate a pdf version of the document using pdfla‐
2649 tex, using the command specified by the $pdflatex variable. If
2650 equal to 2, generate a pdf version of the document from the ps
2651 file, by using the command specified by the $ps2pdf variable.
2652 If equal to 3, generate a pdf version of the document from the
2653 dvi file, by using the command specified by the $dvipdf vari‐
2654 able. If equal to 4, generate a pdf version of the document
2655 using lualatex, using the command specified by the $lualatex
2656 variable. If equal to 5, generate a pdf version (and an xdv
2657 version) of the document using xelatex, using the commands spec‐
2658 ified by the $xelatex and xdvipdfmx variables.
2659
2660 In $pdf_mode=2, it is ensured that .dvi and .ps files are also
2661 made. In $pdf_mode=3, it is ensured that a .dvi file is also
2662 made. But this may be overridden by the document.
2663
2664 $pdflatex ["pdflatex %O %S"]
2665 Specifies the command line for the LaTeX processing program in a
2666 version that makes a pdf file instead of a dvi file.
2667
2668 An example use of this variable is to add certain options to the
2669 command line for the program, e.g.,
2670
2671 $pdflatex = "pdflatex --shell-escape %O %S";
2672
2673 (In some earlier versions of latexmk, you needed to use an
2674 assignment to $pdflatex to allow the use of lualatex or xelatex
2675 instead of pdflatex. There are now separate configuration vari‐
2676 ables for the use of lualatex or xelatex. See $lualatex and
2677 $xelatex.)
2678
2679 To do a coordinated setting of all of $latex, $pdflatex, $luala‐
2680 tex, and $xelatex, see the section "Advanced Configuration".
2681
2682 %pdflatex_input_extensions
2683 This variable specifies the extensions tried by latexmk when it
2684 finds that a pdflatex run resulted in an error that a file has
2685 not been found, and the file is given without an extension.
2686 This typically happens when LaTeX commands of the form
2687 \input{file} or \includegraphics{figure}, when the relevant
2688 source file does not exist.
2689
2690 In this situation, latexmk searches for custom dependencies to
2691 make the missing file(s), but restricts it to the extensions
2692 specified by the variable %pdflatex_input_extensions. The
2693 default extensions are 'tex', 'pdf', 'jpg, and 'png'.
2694
2695 See details of the %latex_input_extensions for other information
2696 that equally applies to %pdflatex_input_extensions.
2697
2698 $pdflatex_silent_switch ["-interaction=batchmode"]
2699 Switch(es) for the pdflatex program (specified in the variable
2700 $pdflatex) when silent mode is on.
2701
2702 See details of the $latex_silent_switch for other information
2703 that equally applies to $pdflatex_silent_switch.
2704
2705 $pdf_previewer ["start acroread %O %S"]
2706 The command to invoke a pdf-previewer.
2707
2708 On MS-Windows, the default is changed to "cmd /c start """;
2709 under more recent versions of Windows, this will cause to be run
2710 whatever command the system has associated with .pdf files. But
2711 this may be undesirable if this association is to acroread --
2712 see the notes in the explanation of the -pvc option.]
2713
2714 On OS-X the default is changed to "open %S", which results in
2715 OS-X starting up (and detaching) the viewer associated with the
2716 file. By default, for pdf files this association is to OS-X's
2717 preview, which is quite satisfactory.
2718
2719 WARNING: Problem under MS-Windows: if acroread is used as the
2720 pdf previewer, and it is actually viewing a pdf file, the pdf
2721 file cannot be updated. Thus makes acroread a bad choice of
2722 previewer if you use latexmk's previous-continuous mode (option
2723 -pvc) under MS-windows. This problem does not occur if, for
2724 example, SumatraPDF or gsview is used to view pdf files.
2725
2726 Important note: Normally you will want to have a previewer run
2727 detached, so that latexmk doesn't wait for the previewer to ter‐
2728 minate before continuing its work. So normally you should pre‐
2729 fix the command by "start ", which flags to latexmk that it
2730 should do the detaching of the previewer itself (by whatever
2731 method is appropriate to the operating system). But sometimes
2732 letting latexmk do the detaching is not appropriate (for a vari‐
2733 ety of non-trivial reasons), so you should put the "start " bit
2734 in yourself, whenever it is needed.
2735
2736 $pdf_update_command [""]
2737 When the pdf previewer is set to be updated by running a com‐
2738 mand, this is the command that is run. See the information for
2739 the variable $pdf_update_method.
2740
2741 $pdf_update_method [1 under UNIX, 3 under MS-Windows]
2742 How the pdf viewer updates its display when the pdf file has
2743 changed. See the information on the variable $dvi_update_method
2744 for the codes. (Note that information needs be changed slightly
2745 so that for the value 4, to run a command to do the update, the
2746 command is specified by the variable $pdf_update_command, and
2747 for the value 2, to specify update by signal, the signal is
2748 specified by $pdf_update_signal.)
2749
2750 Note that acroread under MS-Windows (but not UNIX) locks the pdf
2751 file, so the default value is then 3.
2752
2753 Arranging to use a command to get a previewer explicitly updated
2754 requires three variables to be set. For example:
2755
2756 $pdf_previewer = "start xpdf -remote %R %O %S";
2757 $pdf_update_method = 4;
2758 $pdf_update_command = "xpdf -remote %R -reload";
2759
2760 The first setting arranges for the xpdf program to be used in
2761 its "remote server mode", with the server name specified as the
2762 rootname of the TeX file. The second setting arranges for
2763 updating to be done in response to a command, and the third set‐
2764 ting sets the update command.
2765
2766 $pdf_update_signal [Under UNIX: SIGHUP, which is a system-dependent
2767 value]
2768 The number of the signal that is sent to the pdf viewer when it
2769 is updated by sending a signal -- see the information on the
2770 variable $pdf_update_method. The default value is the one
2771 appropriate for gv on a UNIX system.
2772
2773 $pid_position[1 under UNIX, -1 under MS-Windows]
2774 The variable $pid_position is used to specify which word in
2775 lines of the output from $pscmd corresponds to the process ID.
2776 The first word in the line is numbered 0. The default value of
2777 1 (2nd word in line) is correct for Solaris 2.6, Linux, and OS-X
2778 with their default settings of $pscmd.
2779
2780 Setting the variable to -1 is used to indicate that $pscmd is
2781 not to be used.
2782
2783 $postscript_mode [0]
2784 If nonzero, generate a postscript version of the document.
2785 Equivalent to the -ps option.
2786
2787 If some other request is made for which a postscript file is
2788 needed, then $postscript_mode will be set to 1.
2789
2790 $pre_tex_code ['']
2791
2792 Sets TeX code to be executed before inputting the source file.
2793 This works if the relevant one of $latex, etc contains a suit‐
2794 able command line with a %P or %U substitution. For example you
2795 could do
2796
2797 $latex = 'latex %O %P';
2798 $pre_tex_code = '\AtBeginDocument{An initial message\par}';
2799
2800 To set all of $latex, $pdflatex, $lualatex, and $xelatex you
2801 could use the subroutine alt_tex_cmds:
2802
2803 &alt_tex_cmds;
2804 $pre_tex_code = '\AtBeginDocument{An initial message\par}';
2805
2806
2807
2808 $preview_continuous_mode [0]
2809 If nonzero, run a previewer to view the document, and continue
2810 running latexmk to keep .dvi up-to-date. Equivalent to the -pvc
2811 option. Which previewer is run depends on the other settings,
2812 see the command line options -view=, and the variable $view.
2813
2814 $preview_mode [0]
2815 If nonzero, run a previewer to preview the document. Equivalent
2816 to the -pv option. Which previewer is run depends on the other
2817 settings, see the command line options -view=, and the variable
2818 $view.
2819
2820 $printout_mode [0]
2821 If nonzero, print the document using the command specified in
2822 the $lpr variable. Equivalent to the -p option. This is recom‐
2823 mended not to be set from an RC file, otherwise you could waste
2824 lots of paper.
2825
2826 $print_type = ["auto"]
2827 Type of file to printout: possibilities are "auto", "dvi",
2828 "none", "pdf", or "ps". See the option -print= for the meaning
2829 of the "auto" value.
2830
2831 $pscmd Command used to get all the processes currently run by the user.
2832 The -pvc option uses the command specified by the variable
2833 $pscmd to determine if there is an already running previewer,
2834 and to find the process ID (needed if latexmk needs to signal
2835 the previewer about file changes).
2836
2837 Each line of the output of this command is assumed to correspond
2838 to one process. See the $pid_position variable for how the
2839 process number is determined.
2840
2841 The default for pscmd is "NONE" under MS-Windows and cygwin
2842 (i.e., the command is not used), "ps -ww -u $ENV{USER}" under
2843 OS-X, and "ps -f -u $ENV{USER}" under other operating systems
2844 (including Linux). In these specifications "$ENV{USER}" is sub‐
2845 stituted by the username.
2846
2847 $ps2pdf ["ps2pdf %O %S %D"]
2848 Command to convert .ps to .pdf file.
2849
2850 $ps_filter [empty]
2851 The postscript file filter to be run on the newly produced post‐
2852 script file before other processing. Equivalent to specifying
2853 the -pF option.
2854
2855 $ps_previewer ["start gv %O %S", but start %O %S under MS-Windows]
2856 The command to invoke a ps-previewer. (The default under MS-
2857 Windows will cause to be run whatever command the system has
2858 associated with .ps files.)
2859
2860 Note that gv could be used with the -watch option updates its
2861 display whenever the postscript file changes, whereas ghostview
2862 does not. However, different versions of gv have slightly dif‐
2863 ferent ways of writing this option. You can configure this
2864 variable appropriately.
2865
2866 WARNING: Linux systems may have installed one (or more) versions
2867 of gv under different names, e.g., ggv, kghostview, etc, but
2868 perhaps not one actually called gv.
2869
2870 Important note: Normally you will want to have a previewer run
2871 detached, so that latexmk doesn't wait for the previewer to ter‐
2872 minate before continuing its work. So normally you should pre‐
2873 fix the command by "start ", which flags to latexmk that it
2874 should do the detaching of the previewer itself (by whatever
2875 method is appropriate to the operating system). But sometimes
2876 letting latexmk do the detaching is not appropriate (for a vari‐
2877 ety of non-trivial reasons), so you should put the "start " bit
2878 in yourself, whenever it is needed.
2879
2880
2881 $ps_previewer_landscape ["start gv -swap %O %S", but start %O %S under
2882 MS-Windows]
2883 The command to invoke a ps-previewer in landscape mode.
2884
2885 $ps_update_command [""]
2886 When the postscript previewer is set to be updated by running a
2887 command, this is the command that is run. See the information
2888 for the variable $ps_update_method.
2889
2890 $ps_update_method [0 under UNIX, 1 under MS-Windows]
2891 How the postscript viewer updates its display when the .ps file
2892 has changed. See the information on the variable
2893 $dvi_update_method for the codes. (Note that information needs
2894 be changed slightly so that for the value 4, to run a command to
2895 do the update, the command is specified by the variable
2896 $ps_update_command, and for the value 2, to specify update by
2897 signal, the signal is specified by $ps_update_signal.)
2898
2899 $ps_update_signal [Under UNIX: SIGHUP, which is a system-dependent
2900 value]
2901 The number of the signal that is sent to the pdf viewer when it
2902 is updated by sending a signal -- see $ps_update_method. The
2903 default value is the one appropriate for gv on a UNIX system.
2904
2905 $pvc_timeout [0]
2906 If this variable is nonzero, there will be a timeout in pvc
2907 mode after a period of inactivity. Inactivity means a period
2908 when latexmk has detected no file changes and hence has not
2909 taken any actions like compiling the document. The period of
2910 inactivity is in the variable $pvc_timeout_mins.
2911
2912
2913 $pvc_timeout_mins [30]
2914 The period of inactivity, in minutes, after which pvc mode times
2915 out. This is used if $pvc_timeout is nonzero.
2916
2917 $pvc_view_file_via_temporary [1]
2918 The same as $always_view_file_via_temporary, except that it only
2919 applies in preview-continuous mode (-pvc option).
2920
2921 $quote_filenames [1]
2922 This specifies whether substitutions for placeholders in command
2923 specifications (as in $pdflatex) are surrounded by double
2924 quotes. If this variable is 1 (or any other value Perl regards
2925 as true), then quoting is done. Otherwise quoting is omitted.
2926
2927 The quoting method used by latexmk is tested to work correctly
2928 under UNIX systems (including Linux and Mac OS-X) and under MS-
2929 Windows. It allows the use of filenames containing special
2930 characters, notably spaces. (But note that many versions of
2931 latex and pdflatex cannot correctly deal with TeX files whose
2932 names contain spaces. Latexmk's quoting only ensures that such
2933 filenames are correctly treated by the operating system in pass‐
2934 ing arguments to programs.)
2935
2936 $recorder [1]
2937 Whether to use the -recorder option to latex and pdflatex. Use
2938 of this option results in a file of extension .fls containing a
2939 list of the files that these programs have read and written.
2940 Latexmk will then use this file to improve its detection of
2941 source files and generated files after a run of latex or pdfla‐
2942 tex.
2943
2944 It is generally recommended to use this option (or to configure
2945 the $recorder variable to be on.) But it only works if
2946 (pdf)latex supports the -recorder option, which is true for most
2947 current implementations
2948
2949 Note about the name of the .fls file: Most implementations of
2950 (pdf)latex produce an .fls file with the same basename as the
2951 main document's LaTeX, e.g., for Document.tex, the .fls file is
2952 Document.fls. However, some implementations instead produce
2953 files named for the program, i.e., latex.fls or pdflatex.fls.
2954 In this second case, latexmk copies the latex.fls or pdfla‐
2955 tex.fls to a file with the basename of the main LaTeX document,
2956 e.g., Document.fls.
2957
2958 $search_path_separator [See below for default]
2959 The character separating paths in the environment variables TEX‐
2960 INPUTS, BIBINPUTS, and BSTINPUTS. This variable is mainly used
2961 by latexmk when the -outdir, -output-directory, -auxdir, and/or
2962 -aux-directory options are used. In that case latexmk needs to
2963 communicate appropriately modified search paths to bibtex,
2964 dvipdf, dvips, and (pdf)latex.
2965
2966 [Comment to technically savvy readers: (pdf)latex doesn't actu‐
2967 ally need the modified search path. But, surprisingly, dvipdf
2968 and dvips do, because sometimes graphics files get generated in
2969 the output or aux directories.]
2970
2971 The default under MSWin and Cygwin is ';' and under UNIX-like
2972 operating systems (including Linux and OS-X) is ':'. Normally
2973 the defaults give correct behavior. But there can be difficul‐
2974 ties if your operating system is of one kind, but some of your
2975 software is running under an emulator for the other kind of
2976 operating system; in that case you'll need to find out what is
2977 needed, and set $search_path_separator explicitly. (The same
2978 goes, of course, for unusual operating systems that are not in
2979 the MSWin, Linux, OS-X, Unix collection.)
2980
2981 $show_time [0]
2982 Whether to show CPU time used.
2983
2984 $silence_logfile_warnings [0]
2985 Whether after a run of (pdf)latex to summarize warnings in the
2986 log file about undefined citations and references. Setting
2987 $silence_logfile_warnings=0 gives the summary of warnings (pro‐
2988 vided silent mode isn't also set), and this is useful to locate
2989 undefined citations and references without searching through the
2990 much more verbose log file or the screen output of (pdf)latex.
2991 But the summary can also be excessively annoying. The default
2992 is not to give these warnings. The command line options
2993 -silence_logfile_warning_list and -silence_logfile_warning_list-
2994 also set this variable.
2995
2996 Note that multiple occurrences for the same undefined object on
2997 the same page and same line will be compressed to a single warn‐
2998 ing.
2999
3000 $silent [0]
3001 Whether to run silently. Setting $silent to 1 has the same
3002 effect as the -quiet of -silent options on the command line.
3003
3004 $sleep_time [2]
3005 The time to sleep (in seconds) between checking for source file
3006 changes when running with the -pvc option. This is subject to a
3007 minimum of one second delay, except that zero delay is also
3008 allowed.
3009
3010 A value of exactly 0 gives no delay, and typically results in
3011 100% CPU usage, which may not be desirable.
3012
3013 $texfile_search [""]
3014 This is an obsolete variable, replaced by the @default_files
3015 variable.
3016
3017 For backward compatibility, if you choose to set $tex‐
3018 file_search, it is a string of space-separated filenames, and
3019 then latexmk replaces @default_files with the filenames in $tex‐
3020 file_search to which is added "*.tex".
3021
3022 $success_cmd [undefined]
3023 See the documentation for $compiling_cmd.
3024
3025 $tmpdir [See below for default]
3026 Directory to store temporary files that latexmk may generate
3027 while running.
3028
3029 The default under MSWindows (including cygwin), is to set
3030 $tmpdir to the value of the first of whichever of the system
3031 environment variables TMPDIR or TEMP exists, otherwise to the
3032 current directory. Under other operating systems (expected to
3033 be UNIX/Linux, including OS-X), the default is the value of the
3034 system environment variable TMPDIR if it exists, otherwise
3035 "/tmp".
3036
3037 $use_make_for_missing_files [0]
3038 Whether to use make to try and make files that are missing after
3039 a run of latex or pdflatex, and for which a custom dependency
3040 has not been found. This is generally useful only when latexmk
3041 is used as part of a bigger project which is built by using the
3042 make program.
3043
3044 Note that once a missing file has been made, no further calls to
3045 make will be made on a subsequent run of latexmk to update the
3046 file. Handling this problem is the job of a suitably defined
3047 Makefile. See the section "USING latexmk WITH make" for how to
3048 do this. The intent of calling make from latexmk is merely to
3049 detect dependencies.
3050
3051 $view ["default"]
3052 Which kind of file is to be previewed if a previewer is used.
3053 The possible values are "default", "dvi", "ps", "pdf". The
3054 value of "default" means that the "highest" of the kinds of file
3055 generated is to be used (among .dvi, .ps and .pdf).
3056
3057
3058 $warnings_as_errors [0]
3059 Normally latexmk copies the behavior of latex in treating unde‐
3060 fined references and citations and multiply defined references
3061 as conditions that give a warning but not an error. The vari‐
3062 able $warnings_as_errors controls whether this behavior is modi‐
3063 fied.
3064
3065 When the variable is non-zero, latexmk at the end of its run
3066 will return a non-zero status code to the operating system if
3067 any of the files processed gives a warning about problems with
3068 citations or references (i.e., undefined citations or references
3069 or multiply defined references). This is after latexmk has com‐
3070 pleted all the runs it needs to try and resolve references and
3071 citations. Thus $warnings_as_errors being nonzero causes
3072 latexmk to treat such warnings as errors, but only when they
3073 occur on the last run of (pdf)latex and only after processing is
3074 complete. A non-zero value $warnings_as_errors can be set by
3075 the command-line option -Werror.
3076
3077 The default behavior is normally satisfactory in the usual edit-
3078 compile-edit cycle. But, for example, latexmk can also be used
3079 as part of a build process for some bigger project, e.g., for
3080 creating documentation in the build of a software application.
3081 Then it is often sensible to treat citation and reference warn‐
3082 ings as errors that require the overall build process to be
3083 aborted. Of course, since multiple runs of (pdf)latex are gen‐
3084 erally needed to resolve references and citations, what matters
3085 is not the warnings on the first run, but the warnings on the
3086 last run; latexmk takes this into account appropriately.
3087
3088 In addition, when preview-continuous mode is used, a non-zero
3089 value for $warnings_as_errors changes the use of the commands
3090 $failure_cmd, $warning_cmd, and $success_cmd after a complia‐
3091 tion. If there are citation or reference warnings, but no other
3092 errors, the behavior is as follows. If $warning_cmd is set, it
3093 is used. If it is not set, then then if $warnings_as_errors is
3094 non-zero and $failure_cmd is set, then $failure_cmd. Otherwise
3095 $success_cmd is used, if it is set. (The foregoing explanation
3096 is rather complicated, because latexmk has to deal with the case
3097 that one or more of the commands isn't set.)
3098
3099
3100 $xdvipdfmx ["xdvipdfmx -o %D %O %S"]
3101
3102 The program to make a pdf file from an xdv file (used in con‐
3103 junction with xelatex when $pdf_mode=5).
3104
3105 $xdvipdfmx_silent_switch ["-q"]
3106 Switch(es) for the xdvipdfmx program when silent mode is on.
3107
3108 $xelatex ["xelatex %O %S"]
3109 Specifies the command line for the LaTeX processing program of
3110 when the xelatex program is called for. See the documentation
3111 of the -xelatex option for some special properties of latexmk's
3112 use of xelatex.
3113
3114 Note about xelatex: Now latexmk uses xelatex to make an .xdv
3115 rather than .pdf file, with the .pdf file being created in a
3116 separate step. This is enforced by the use of the -no-pdf
3117 option. If %O is part of the command for invoking xelatex, then
3118 latexmk will insert the -no-pdf option automatically, otherwise
3119 you must provide the option yourself
3120
3121 To do a coordinated setting of all of $latex, $pdflatex, $luala‐
3122 tex, and $xelatex, see the section "Advanced Configuration".
3123
3124
3125 %xelatex_input_extensions
3126 This variable specifies the extensions tried by latexmk when it
3127 finds that an xelatex run resulted in an error that a file has
3128 not been found, and the file is given without an extension.
3129 This typically happens when LaTeX commands of the form
3130 \input{file} or \includegraphics{figure}, when the relevant
3131 source file does not exist.
3132
3133 In this situation, latexmk searches for custom dependencies to
3134 make the missing file(s), but restricts it to the extensions
3135 specified by the variable %xelatex_input_extensions. The
3136 default extensions are 'tex', 'pdf', 'jpg, and 'png'.
3137
3138 See details of the %latex_input_extensions for other information
3139 that equally applies to %xelatex_input_extensions.
3140
3141 $xelatex_silent_switch ["-interaction=batchmode"]
3142 Switch(es) for the xelatex program (specified in the variable
3143 $xelatex) when silent mode is on.
3144
3145 See details of the $latex_silent_switch for other information
3146 that equally applies to $xelatex_silent_switch.
3147
3148
3149
3150
3152 In any RC file a set of custom dependencies can be set up to convert a
3153 file with one extension to a file with another. An example use of this
3154 would be to allow latexmk to convert a .fig file to .eps to be included
3155 in the .tex file.
3156
3157
3158 Defining a custom dependency:
3159 The old method of configuring latexmk to use a custom dependency was to
3160 directly manipulate the @cus_dep_list array that contains information
3161 defining the custom dependencies. (See the section "Old Method of
3162 Defining Custom Dependencies" for details.) This method still works,
3163 but is no longer preferred.
3164
3165 A better method is to use the subroutines that allow convenient manipu‐
3166 lations of the custom dependency list. These are
3167
3168 add_cus_dep( fromextension, toextension, must, subroutine )
3169 remove_cus_dep( fromextension, toextension )
3170 show_cus_dep()
3171
3172 The arguments are as follows:
3173
3174 from extension:
3175 The extension of the file we are converting from (e.g. "fig").
3176 It is specified without a period.
3177
3178 to extension:
3179 The extension of the file we are converting to (e.g. "eps"). It
3180 is specified without a period.
3181
3182 must: If non-zero, the file from which we are converting must exist,
3183 if it doesn't exist latexmk will give an error message and exit
3184 unless the -f option is specified. If must is zero and the file
3185 we are converting from doesn't exist, then no action is taken.
3186 Generally, the appropriate value of must is zero.
3187
3188 function:
3189 The name of the subroutine that latexmk should call to perform
3190 the file conversion. The first argument to the subroutine is
3191 the base name of the file to be converted without any extension.
3192 The subroutines are declared in the syntax of Perl. The func‐
3193 tion should return 0 if it was successful and a nonzero number
3194 if it failed.
3195
3196
3197 Naturally add_cus_dep adds a custom dependency with the specified from
3198 and to extensions. If a custom dependency has been previously defined
3199 (e.g., in an rcfile that was read earlier), then it is replaced by the
3200 new one.
3201
3202 The subroutine remove_cus_dep removes the specified custom dependency.
3203 The subroutine show_cus_dep causes a list of the currently defined cus‐
3204 tom dependencies to be sent to the screen output.
3205
3206
3207 How custom dependencies are used:
3208 An instance of a custom dependency rule is created whenever latexmk
3209 detects that a run of latex/pdflatex needs to read a file, like a
3210 graphics file, whose extension is the to-extension of a custom depen‐
3211 dency. Then latexmk examines whether a file exists with the same name,
3212 but with the corresponding from-extension, as specified in the custom-
3213 dependency. If it does, then a corresponding instance of the custom
3214 dependency is created, after which the rule is invoked whenever the
3215 destination file (the one with the to-extension) is out-of-date with
3216 respect to the corresponding source file.
3217
3218 To make the new destination file, the Perl subroutine specified in the
3219 rule is invoked, with an argument that is the base name of the files in
3220 question. Simple cases just involve a subroutine invoking an external
3221 program; this can be done by following the templates below, even by
3222 those without knowledge of the Perl programming language. Of course,
3223 experts could do something much more elaborate.
3224
3225 One item in the specification of each custom-dependency rule, labeled
3226 "must" above, specifies how the rule should be applied when the source
3227 file fails to exist.
3228
3229 When latex reports that an input file (e.g., a graphics file) does not
3230 exist, latexmk tries to find a source file and a custom dependency that
3231 can be used to make it. If it succeeds, then it creates an instance of
3232 the custom dependency and invokes it to make the missing file, after
3233 which the next pass of latex etc will be able to read the newly created
3234 file.
3235
3236 Note for advanced usage: The operating system's environment variable
3237 TEXINPUTS can be used to specify a search path for finding files by
3238 latex etc. Correspondingly, when a missing file is reported, latexmk
3239 looks in the directories specified in TEXINPUTS as well as in the cur‐
3240 rent directory, to find a source file from which an instance of a cus‐
3241 tom dependency can be used to make the missing file.
3242
3243
3244 Function to implement custom dependency, traditional method:
3245 The function that implements a custom dependency gets the information
3246 on the files to be processed in two ways. The first is through its one
3247 argument; the argument contains the base name of the source and desti‐
3248 nation files. The second way is described later.
3249
3250 A simple and typical example of code in an initialization rcfile using
3251 the first method is:
3252
3253 add_cus_dep( 'fig', 'eps', 0, 'fig2eps' );
3254 sub fig2eps {
3255 system( "fig2dev -Leps \"$_[0].fig\" \"$_[0].eps\"" );
3256 }
3257
3258 The first line adds a custom dependency that converts a file with
3259 extension "fig", as created by the xfig program, to an encapsulated
3260 postscript file, with extension "eps". The remaining lines define a
3261 subroutine that carries out the conversion. If a rule for converting
3262 "fig" to "eps" files already exists (e.g., from a previously read-in
3263 initialization file), the latexmk will delete this rule before making
3264 the new one.
3265
3266 Suppose latexmk is using this rule to convert a file "figure.fig" to
3267 "figure.eps". Then it will invoke the fig2eps subroutine defined in
3268 the above code with a single argument "figure", which is the basename
3269 of each of the files (possibly with a path component). This argument
3270 is referred to by Perl as $_[0]. In the example above, the subroutine
3271 uses the Perl command system to invoke the program fig2dev. The double
3272 quotes around the string are a Perl idiom that signify that each string
3273 of the form of a variable name, $_[0] in this case, is to be substi‐
3274 tuted by its value.
3275
3276 If the return value of the subroutine is non-zero, then latexmk will
3277 assume an error occurred during the execution of the subroutine. In
3278 the above example, no explicit return value is given, and instead the
3279 return value is the value returned by the last (and only) statement,
3280 i.e., the invocation of system, which returns the value 0 on success.
3281
3282 If you use pdflatex instead of latex, then you will probably prefer to
3283 convert your graphics files to pdf format, in which case you would
3284 replace the above code in an initialization file by
3285
3286 add_cus_dep( 'fig', 'pdf, 0, 'fig2pdf' );
3287 sub fig2pdf {
3288 system( "fig2dev -Lpdf \"$_[0].fig\" \"$_[0].pdf\"" );
3289 }
3290
3291 Note 1: In the command lines given in the system commands in the above
3292 examples, double quotes have been inserted around the file names
3293 (implemented by '\"' in the Perl language). They immunize the running
3294 of the program against special characters in filenames. Very often
3295 these quotes are not necessary, i.e., they can be omitted. But it is
3296 normally safer to keep them in. Even though the rules for quoting vary
3297 between operating systems, command shells and individual pieces of
3298 software, the quotes in the above examples do not cause problems in the
3299 cases I have tested.
3300
3301 Note 2: One case in which the quotes are important is when the files
3302 are in a subdirectory and your operating system is Microsoft Windows.
3303 Then the separator character for directory components can be either a
3304 forward slash '/' or Microsoft's more usual backward slash ´\'. For‐
3305 ward slashes are generated by latexmk, to maintain its sanity from
3306 software like MiKTeX that mixes both directory separators; but their
3307 correct use normally requires quoted filenames. (See a log file from a
3308 run of MiKTeX (at least in v. 2.9) for an example of the use of both
3309 directory separators.)
3310
3311 Note 3: The subroutines implementing custom dependencies in the exam‐
3312 ples given just have a single line invoking an external program.
3313 That's the usual situation. But since the subroutines are in the Perl
3314 language, you can implement much more complicated processing if you
3315 need it.
3316
3317
3318 Removing custom dependencies, and when you might need to do this:
3319 If you have some general custom dependencies defined in the system or
3320 user initialization file, you may find that for a particular project
3321 they are undesirable. So you might want to delete the unneeded ones.
3322 A situation where this would be desirable is where there are multiple
3323 custom dependencies with the same from-extension or the same to-exten‐
3324 sion. In that case, latexmk might choose a different one from the one
3325 you want for a specific project. As an example, to remove any "fig" to
3326 "eps" rule you would use:
3327
3328 remove_cus_dep( 'fig', 'eps' );
3329
3330 If you have complicated sets of custom dependencies, you may want to
3331 get a listing of the custom dependencies. This is done by using the
3332 line
3333
3334 show_cus_dep();
3335
3336 in an initialization file.
3337
3338
3339 Function implementing custom dependency, alternative methods:
3340 So far the examples for functions to implement custom dependencies have
3341 used the argument of the function to specify the base name of converted
3342 file. This method has been available since very old versions of
3343 latexmk, and many examples can be found, e.g., on the web.
3344
3345 However in later versions of latexmk the internal structure of the
3346 implementation of its "rules" for the steps of processing, including
3347 custom dependencies, became much more powerful. The function imple‐
3348 menting a custom dependency is executed within a special context where
3349 a number of extra variables and subroutines are defined. Publicly doc‐
3350 umented ones, intended to be long-term stable, are listed below, under
3351 the heading "Variables and subroutines for processing a rule".
3352
3353 Examples of their use is given in the following examples, concerning
3354 multiple index files and glossaries.
3355
3356 The only index-file conversion built-in to latexmk is from an ".idx"
3357 file written on one run of latex/pdflatex to an ".ind" file to be read
3358 in on a subsequent run. But with the index.sty package, for example,
3359 you can create extra indexes with extensions that you configure.
3360 Latexmk does not know how to deduce the extensions from the information
3361 it has. But you can easily write a custom dependency. For example if
3362 your latex file uses the command "\newindex{special}{ndx}{nnd}{Special
3363 index}" you will need to get latexmk to convert files with the exten‐
3364 sion .ndx to .nnd. The most elementary method is to define a custom
3365 dependency as follows:
3366
3367 add_cus_dep( 'ndx', 'nnd', 0, 'ndx2nnd' );
3368 sub ndx2nnd {
3369 return system( "makeindex -o \"$_[0].nnd\" \"$_[0].ndx\"" );
3370 }
3371 push @generated_exts, 'ndx', 'nnd';
3372
3373 Notice the added line compared with earlier examples. The extra line
3374 gets the extensions "ndx" and "nnd" added to the list of extensions for
3375 generated files; then the extra index files will be deleted by clean-up
3376 operations
3377
3378 But if you have yet more indexes with yet different extensions, e.g.,
3379 "adx" and "and", then you will need a separate function for each pair
3380 of extensions. This is quite annoying. You can use the Run_subst
3381 function to simplify the definitions to use a single function:
3382
3383 add_cus_dep( 'ndx', 'nnd', 0, 'dx2nd' );
3384 add_cus_dep( 'adx', 'and', 0, 'dx2nd' );
3385 sub dx2nd {
3386 return Run_subst( "makeindex -o %D %S" );
3387 }
3388 push @generated_exts, 'ndx', 'nnd', 'adx', 'and';
3389
3390 You could also instead use
3391
3392 add_cus_dep( 'ndx', 'nnd', 0, 'dx2nd' );
3393 add_cus_dep( 'adx', 'and', 0, 'dx2nd' );
3394 sub dx2nd {
3395 return Run_subst( $makeindex );
3396 }
3397 push @generated_exts, 'ndx', 'nnd', 'adx', 'and';
3398
3399 This last example uses the command specification in $makeindex, and so
3400 any customization you have made for the standard index also applies to
3401 your extra indexes.
3402
3403 Similar techniques can be applied for glossaries.
3404
3405 Those of you with experience with Makefiles, may get concerned that the
3406 .ndx file is written during a run of latex/pdflatex and is always later
3407 than the .nnd last read in. Thus the .nnd appears to be perpetually
3408 out-of-date. This situation, of circular dependencies, is endemic to
3409 latex, and is one of the issues that latexmk is programmed to overcome.
3410 It examines the contents of the files (by use of a checksum), and only
3411 does a remake when the file contents have actually changed.
3412
3413 Of course if you choose to write random data to the .nnd (or the .aux
3414 file, etc) that changes on each new run, then you will have a problem.
3415 For real experts: See the %hash_cal_ignore_pattern if you have to deal
3416 with such problems.
3417
3418
3419 Old Method of Defining Custom Dependencies:
3420 In much older versions of latexmk, the only method of defining custom
3421 dependencies was to directly manipulate the table of custom dependen‐
3422 cies. This is contained in the @cus_dep_list array. It is an array of
3423 strings, and each string in the array has four items in it, each sepa‐
3424 rated by a space, the from-extension, the to-extension, the "must"
3425 item, and the name of the subroutine for the custom dependency. These
3426 were all defined above.
3427
3428 An example of the old method of defining custom dependencies is as fol‐
3429 lows. It is the code in an RC file to ensure automatic conversion of
3430 .fig files to .eps files:
3431
3432 push @cus_dep_list, "fig eps 0 fig2eps";
3433 sub fig2eps {
3434 return system( "fig2dev -Lps \"$_[0].fig\" \"$_[0].eps\"" );
3435 }
3436
3437 This method still works, and is almost equivalent to the code given
3438 earlier that used the add_cus_dep subroutine. However, the old method
3439 doesn't delete any previous custom-dependency for the same conversion.
3440 So the new method is preferable.
3441
3442
3443
3445 For most purposes, simple configuration for latexmk along the lines of
3446 the examples given is sufficient. But sometimes you need something
3447 harder. In this section, I indicate some extra possibilities. Gener‐
3448 ally to use these, you need to be fluent in the Perl language, since
3449 this is what is used in the rc files.
3450
3451 See also the section DEALING WITH ERRORS, PROBLEMS, ETC. See also the
3452 examples in the directory example_rcfiles in the latexmk distributions.
3453 Even if none of the examples apply to your case, they may give you use‐
3454 ful ideas
3455
3456
3457 Utility subroutines
3458 ensure_path( var, values ...)
3459
3460 The first parameter is the name of one of the system's environ‐
3461 ment variables for search paths. The remaining parameters are
3462 values that should be in the variable. For each of the value
3463 parameters, if it isn't already in the variable, then it is
3464 prepended to the variable; in that case the environment variable
3465 is created if it doesn't already exist. For separating values,
3466 the character appropriate the the operating system is used --
3467 see the configuration variable $search_path_separator.
3468
3469 Example:
3470
3471 ensure_path( 'TEXINPUTS', './custom_cls_sty_files//' );
3472
3473 (In this example, the trailing '//' is documented by TeX systems
3474 to mean that latex, pdflatex, etc search for files in the speci‐
3475 fied directory and in all subdirectories.)
3476
3477 Technically ensure_path works by setting Perl's variable
3478 $ENV{var}, where var is the name of the target variable. The
3479 changed value is then passed as an environment variable to any
3480 invoked programs.
3481
3482
3483 Variables and subroutines for processing a rule
3484 A step in the processing is called a rule. One possibility to implement
3485 the processing of a rule is by a Perl subroutine. This is always the
3486 case for custom dependencies. Also, for any other rule, you can use a
3487 subroutine by prefixing the command specification by the word "inter‐
3488 nal" -- see the section FORMAT OF COMMAND SPECIFICATIONS.
3489
3490 When you use a subroutine for processing a rule, all the possibilities
3491 of Perl programming are available, of course. In addition, some of
3492 latexmk's internal variables and subroutines are available. The ones
3493 listed below are intended to be available to (advanced) users, and
3494 their specifications will generally have stability under upgrades. Gen‐
3495 erally, the variables should be treated as read-only: Changing their
3496 values can have bad consequences, since it is liable to mess up the
3497 consistency of what latexmk is doing.
3498
3499 $rule This variable has the name of the rule, as known to latexmk.
3500 Note that the exact contents of this variable for a given rule
3501 may be dependent on the version of latexmk
3502
3503 $$Psource
3504 This gives the name of the primary source file. Note the double
3505 dollar signs.
3506
3507 $$Pdest
3508 This gives the name of the main output file if any. Note the
3509 double dollar signs.
3510
3511 rdb_ensure_file( $rule, file )
3512 This a subroutine that ensures that the given file is among the
3513 source files for the specified rule. It is typically used when,
3514 during the processing of a rule, it is known that a particular
3515 extra file is among the dependencies that latexmk should know,
3516 but its default methods don't find the dependency. Almost always
3517 the first argument is the name of the rule currently being pro‐
3518 cessed, so it is then appropriate to specify it by $rule.
3519
3520 For examples of its use, see some of the files in the directory
3521 example_rcfiles of latexmk's distribution. Currently the cases
3522 that use this subroutine are bib2gls-latexmkrc, excel‐
3523 tex_latexmkrc and texinfo-latexmkrc. These illustrate typical
3524 cases where latexmk's normal processing fails to detect certain
3525 extra source files.
3526
3527 rdb_remove_files( $rule, file, ... )
3528 This subroutine removes one or more files from the dependency
3529 list for the given rule.
3530
3531 rdb_list_source( $rule )
3532 This subroutine returns the list of source files (i.e., the
3533 dependency list) for the given rule.
3534
3535 rdb_set_source( $rule, file, ... )
3536
3537 rdb_set_source( $rule, @files )
3538 This subroutine sets the dependency list for the given rule to
3539 be the specified files. Files that are already in the list have
3540 unchanged information. Files that were not in the list are
3541 added to it. Files in the previous dependency list that are not
3542 in the newly specified list of files are removed from the depen‐
3543 dency list.
3544
3545 Run_subst( command_spec )
3546 This subroutine runs the command specified by command_spec. The
3547 specification is a string in the format listed in the section
3548 "Format of Command Specifications". An important action of the
3549 Run_subst is to make substitutions of placeholders, e.g., %S and
3550 %D for source and destination files; these get substituted
3551 before the command is run. In addition, the command after sub‐
3552 stitution is printed to the screen unless latexmk is running in
3553 silent mode.
3554
3555
3556 Coordinated Setting of Commands for *latex
3557 To set all of $latex, $pdflatex, $lualatex, and $xelatex to a common
3558 pattern, you can use one of the following subroutines, std_tex_cmds,
3559 alt_tex_cmds, and set_tex_cmds.
3560
3561 They work as follows
3562
3563 &std_tex_cmds;
3564
3565 This results in $latex = 'latex %O %S', and similarly for $pdflatex,
3566 $lualatex, and $xelatex. Note the ampersand in the invocation; this
3567 indicates to Perl that a subroutine is being called.
3568
3569 &alt_tex_cmds;
3570
3571 This results in $latex = 'latex %O %P', and similarly for $pdflatex,
3572 $lualatex, and $xelatex. Note the ampersand in the invocation; this
3573 indicates to Perl that a subroutine is being called.
3574
3575 set_tex_cmds( CMD_SPEC );
3576
3577 Here CMD_SPEC is the command line without the program name. This
3578 results in $latex = 'CMD_SPEC', and similarly for $pdflatex, $lualatex,
3579 and $xelatex. An example would be
3580
3581 set_tex_cmds( '--interaction=batchmode %O %S' );
3582
3583
3584 Advanced configuration: Using latexmk with make
3585 This section is targeted only at advanced users who use the make pro‐
3586 gram for complex projects, as for software development, with the depen‐
3587 dencies specified by a Makefile.
3588
3589 Now the basic task of latexmk is to run the appropriate programs to
3590 make a viewable version of a LaTeX document. However, the usual make
3591 program is not suited to this purpose for at least two reasons. First
3592 is that the use of LaTeX involves circular dependencies (e.g., via .aux
3593 files), and these cannot be handled by the standard make program. Sec‐
3594 ond is that in a large document the set of source files can change
3595 quite frequently, particularly with included graphics files; in this
3596 situation keeping a Makefile manually updated is inappropriate and
3597 error-prone, especially when the dependencies can be determined auto‐
3598 matically. Latexmk solves both of these problems robustly.
3599
3600 Thus for many standard LaTeX documents latexmk can be used by itself
3601 without the make program. In a complex project it simply needs to be
3602 suitably configured. A standard configuration would be to define cus‐
3603 tom dependencies to make graphics files from their source files (e.g.,
3604 as created by the xfig program). Custom dependencies are latexmk's
3605 equivalent of pattern rules in Makefiles.
3606
3607 Nevertheless there are projects for which a Makefile is appropriate,
3608 and it is useful to know how to use latexmk from a Makefile. A typical
3609 example would be to generate documentation for a software project.
3610 Potentially the interaction with the rest of the rules in the Makefile
3611 could be quite complicated, for example if some of the source files for
3612 a LaTeX document are generated by the project's software.
3613
3614 In this section, I give a couple of examples of how latexmk can be use‐
3615 fully invoked from a Makefile. The examples use specific features of
3616 current versions of GNU make, which is the default on both linux and
3617 OS-X systems. They may need modifications for other versions of make.
3618
3619 The simplest method is simply to delegate all the relevant tasks to
3620 latexmk, as is suitable for a straightforward LaTeX document. For this
3621 a suitable Makefile is like
3622
3623 .PHONY : FORCE_MAKE
3624 all : try.pdf
3625 %.pdf : %.tex FORCE_MAKE
3626 latexmk -pdf -dvi- -ps- $<
3627
3628 (Note: the last line must be introduced by a tab for the Makefile to
3629 function correctly!) Naturally, if making try.pdf from its associated
3630 LaTeX file try.tex were the only task to be performed, a direct use of
3631 latexmk without a Makefile would normally be better. The benefit of
3632 using a Makefile for a LaTeX document would be in a larger project,
3633 where lines such as the above would be only be a small part of a larger
3634 Makefile.
3635
3636 The above example has a pattern rule for making a .pdf file from a .tex
3637 file, and it is defined to use latexmk in the obvious way. There is a
3638 conventional default target named "all", with a prerequisite of
3639 try.pdf. So when make is invoked, by default it makes try.pdf. The
3640 only complication is that there may be many source files beyond
3641 try.tex, but these aren't specified in the Makefile, so changes in them
3642 will not by themselves cause latexmk to be invoked. Instead, the pat‐
3643 tern rule is equipped with a "phony" prerequisite FORCE_MAKE; this has
3644 the effect of causing the rule to be always out-of-date, so that
3645 latexmk is always run. It is latexmk that decides whether any action
3646 is needed, e.g., a rerun of pdflatex. Effectively the Makefile dele‐
3647 gates all decisions to latexmk, while make has no knowledge of the list
3648 of source files except for primary LaTeX file for the document. If
3649 there are, for example, graphics files to be made, these must be made
3650 by custom dependencies configured in latexmk.
3651
3652 But something better is needed in more complicated situations, for
3653 example, when the making of graphics files needs to be specified by
3654 rules in the Makefile. To do this, one can use a Makefile like the
3655 following:
3656
3657 TARGETS = document1.pdf document2.pdf
3658 DEPS_DIR = .deps
3659 LATEXMK = latexmk -recorder -use-make -deps \
3660 -e 'warn qq(In Makefile, turn off custom dependencies\n);' \
3661 -e '@cus_dep_list = ();' \
3662 -e 'show_cus_dep();'
3663 all : $(TARGETS)
3664 $(foreach file,$(TARGETS),$(eval -include $(DEPS_DIR)/$(file)P))
3665 $(DEPS_DIR) :
3666 mkdir $@
3667 %.pdf : %.tex
3668 if [ ! -e $(DEPS_DIR) ]; then mkdir $(DEPS_DIR); fi
3669 $(LATEXMK) -pdf -dvi- -ps- -deps-out=$(DEPS_DIR)/$@P $<
3670 %.pdf : %.fig
3671 fig2dev -Lpdf $< $@
3672
3673 (Again, the lines containing the commands for the rules should be
3674 started with tabs.) This example was inspired by how GNU automake han‐
3675 dles automatic dependency tracking of C source files.
3676
3677 After each run of latexmk, dependency information is put in a file in
3678 the .deps subdirectory. The Makefile causes these dependency files to
3679 be read by make, which now has the full dependency information for each
3680 target .pdf file. To make things less trivial it is specificed that
3681 two files document1.pdf and document2.pdf are the targets. The depen‐
3682 dency files are .deps/document1.pdfP and .deps/document2.pdfP.
3683
3684 There is now no need for the phony prerequisite for the rule to make
3685 .pdf files from .tex files. But I have added a rule to make .pdf files
3686 from .fig files produced by the xfig program; these are commonly used
3687 for graphics insertions in LaTeX documents. Latexmk is arranged to
3688 output a dependency file after each run. It is given the -recorder
3689 option, which improves its detection of files generated during a run of
3690 pdflatex; such files should not be in the dependency list. The -e
3691 options are used to turn off all custom dependencies, and to document
3692 this. Instead the -use-make is used to delegate the making of missing
3693 files to make itself.
3694
3695 Suppose in the LaTeX file there is a command \includegraphics{graph},
3696 and an xfig file "graph.fig" exists. On a first run, pdflatex reports
3697 a missing file, named "graph". Latexmk succeeds in making "graph.pdf"
3698 by calling "make graph.pdf", and after completion of its work, it lists
3699 "fig.pdf" among the dependents of the file latexmk is making. Then let
3700 "fig.fig" be updated, and then let make be run. Make first remakes
3701 "fig.pdf", and only then reruns latexmk.
3702
3703 Thus we now have a method by which all the subsidiary processing is
3704 delegated to make.
3705
3706
3708 latex(1), bibtex(1), lualatex(1), pdflatex(1), xelatex(1).
3709
3711 Sometimes a viewer (gv) tries to read an updated .ps or .pdf file after
3712 its creation is started but before the file is complete. Work around:
3713 manually refresh (or reopen) display. Or use one of the other preview‐
3714 ers and update methods.
3715
3716 (The following isn't really a bug, but concerns features of preview‐
3717 ers.) Preview continuous mode only works perfectly with certain pre‐
3718 viewers: Xdvi on UNIX/Linux works for dvi files. Gv on UNIX/Linux
3719 works for both postscript and pdf. Ghostview on UNIX/Linux needs a
3720 manual update (reopen); it views postscript and pdf. Gsview under MS-
3721 Windows works for both postscript and pdf, but only reads the updated
3722 file when its screen is refreshed. Acroread under UNIX/Linux views
3723 pdf, but the file needs to be closed and reopened to view an updated
3724 version. Under MS-Windows, acroread locks its input file and so the
3725 pdf file cannot be updated. (Remedy: configure latexmk to use suma‐
3726 trapdf instead.)
