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, which copies the behavior of earlier versions when only latex was
22 available.
23
24 Latexmk can also be set to run continuously with a suitable previewer.
25 In that case the latex program (or one of its relatives), etc, are
26 rerun whenever one of the source files is modified, and the previewer
27 automatically updates the on-screen view of the compiled document.
28
29 Latexmk determines which are the source files by examining the log
30 file. (Optionally, it also examines the list of input and output files
31 generated by the -recorder option of modern versions of latex (and
32 pdflatex, xelatex, lualatex). See the documentation for the -recorder
33 option of latexmk below.) When latexmk is run, it examines properties
34 of the source files, and if any have been changed since the last docu‐
35 ment generation, latexmk will run the various LaTeX processing programs
36 as necessary. In particular, it will repeat the run of latex (or a
37 related program)) often enough to resolve all cross references; depend‐
38 ing on the macro packages used. With some macro packages and document
39 classes, four, or even more, runs may be needed. If necessary, latexmk
40 will also run bibtex, biber, and/or makeindex. In addition, latexmk
41 can be configured to generate other necessary files. For example, from
42 an updated figure file it can automatically generate a file in encapsu‐
43 lated postscript or another suitable format for reading by 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 can now be con‐
74 figured to run multiple commands. This also extends the possibility of
75 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 the documentation, '*latex' means any of the supported
112 engines, i.e., currently latex, lualatex, pdflatex, xelatex. Mention
113 of a specific one of these normally refers that specific engines. Ear‐
114 lier versions of this documentation weren't so consistent.
115
116 Note 2: In addition to the options in the list below, latexmk recog‐
117 nizes almost all the options recognized by the *latex in their current
118 TeXLive and MiKTeX implementations. Some of the options for these pro‐
119 grams also trigger special action or behavior by latexmk, in which case
120 they have specific explanations in this document. Otherwise, they are
121 just passed through to a called *latex program. Run latexmk with the
122 -showextraoptions to get a list of the options that latexmk accepts and
123 that are simply passed through to *latex. See also the explanation of
124 the -showextraoptions option for more information.
125
126 Note 3: In this documentation, the term *latex is often referred to,
127 which refers to all the supported latex-like programs, whether the
128 original latex, or the later pdflatex, xelatex, and lualatex. Users
129 should know that from latexmk's point of view, all of these programs
130 behave very much alike, with the sole exception that by default latex
131 produces a dvi file and all the others produce a pdf file. Latexmk can
132 be easily configured to use whichever of these programs is needed. See
133 the documentation for the following options: -pdflua, -pdfxe, -luala‐
134 tex, and -xelatex, and also see the documentation for the $latex,
135 $pdflatex, $lualatex, and $xelatex configuration variables. At present
136 latexmk does not do automatic detection of which program is to be used.
137
138
139 Definitions of options and arguments
140
141
142 file One or more files can be specified. If no files are specified,
143 latexmk will, by default, run on all files in the current work‐
144 ing directory with a ".tex" extension. This behavior can be
145 changed: see the description concerning the @default_files vari‐
146 able in the section "List of configuration variables usable in
147 initialization files".
148
149 If a file is specified without an extension, then the ".tex"
150 extension is automatically added, just as LaTeX does. Thus, if
151 you specify:
152
153 latexmk foo
154
155 then latexmk will operate on the file "foo.tex".
156
157 There are certain restrictions on what characters can be in a
158 filename; certain characters are either prohibited or problem‐
159 atic for the latex etc programs. These characters are: "$",
160 "%", "\", "~", the double quote character, and the control char‐
161 acters null, tab, form feed, carriage return, line feed, and
162 delete. In addition "&" is prohibited when it is the first
163 character of a filename.
164
165 Latexmk gives a fatal error when it detects any of the above
166 characters in the TeX filename(s) specified on the command line.
167 However before testing for illegal characters, latexmk removes
168 matching pairs of double quotes from a filename. This matches
169 the behavior of latex etc, and deals with problems that occa‐
170 sionally result from filenames that have been incorrectly quoted
171 on the command line. In addition, under Microsoft Windows, the
172 forward slash character "\" is a directory separator, so latexmk
173 replaces it by a backward slash "/", which is also a legal
174 directory separator in Windows, and is accepted by latex etc.
175
176
177 -auxdir=FOO or -aux-directory=FOO
178 Sets the directory for auxiliary output files of *latex (.aux,
179 .log etc). This achieves its effect by the -aux-directory
180 option of *latex, which currently is only implemented on the
181 MiKTeX version of *latex.
182
183 See also the -outdir/-output-directory options, and the
184 $aux_dir, $out_dir, and $search_path_separator configuration
185 variables of latexmk. In particular, see the documentation of
186 $out_dir for some complications on what directory names are
187 suitable.
188
189 If you also use the -cd option, and the specified auxiliary out‐
190 put directory is a relative path, then the path is interpreted
191 relative to the document directory.
192
193
194 -bibtex
195 When the source file uses bbl files for bibliography, run bibtex
196 or biber as needed to regenerate the bbl files.
197
198 This property can also be configured by setting the $bibtex_use
199 variable to 2 in a configuration file.
200
201
202 -bibtex-
203 Never run bibtex or biber. Also, always treat .bbl files as
204 precious, i.e., do not delete them in a cleanup operation.
205
206 A common use for this option is when a document comes from an
207 external source, complete with its bbl file(s), and the user
208 does not have the corresponding bib files available. In this
209 situation use of the -bibtex- option will prevent latexmk from
210 trying to run bibtex or biber, which would result in overwriting
211 of the bbl files.
212
213 This property can also be configured by setting the $bibtex_use
214 variable to 0 in a configuration file.
215
216
217 -bibtex-cond
218 When the source file uses bbl file(s) for the bibliography, run
219 bibtex or biber as needed to regenerate the bbl files, but only
220 if the relevant bib file(s) exist. Thus when the bib files are
221 not available, bibtex or biber is not run, thereby avoiding
222 overwriting of the bbl file(s). Also, always treat .bbl files
223 as precious, i.e., do not delete them in a cleanup operation.
224
225 This is the default setting. It can also be configured by set‐
226 ting the $bibtex_use variable to 1 in a configuration file.
227
228 The reason for using this setting is that sometimes a .bbl file
229 is available containing the bibliography for a document, but the
230 .bib file is not available. An example would be for a scien‐
231 tific journal where authors submit .tex and .bbl files, but not
232 the original .bib file. In that case, running bibtex or biber
233 would not work, and the .bbl file should be treated as a user
234 source file, and not as a file that can be regenerated on
235 demand.
236
237 (Note that it is possible for latexmk to decide that the bib
238 file does not exist, even though the bib file does exist and
239 bibtex or biber finds it. The problem is that the bib file may
240 not be in the current directory but in some search path; the
241 places latexmk and bibtex or biber cause to be searched need not
242 be identical. On modern installations of TeX and related pro‐
243 grams this problem should not arise, since latexmk uses the
244 kpsewhich program to do the search, and kpsewhich should use the
245 same search path as bibtex and biber. If this problem arises,
246 use the -bibtex option when invoking latexmk.)
247
248 Note that this value does not work properly if the document uses
249 biber instead of bibtex. (There's a long story why not.)
250
251
252 -bibtex-cond1
253 The same as -bibtex-cond1 except that .bbl files are only
254 treated as precious if one or more bibfiles fails to exist.
255
256 Thus if all the bib files exist, bibtex or biber is run to gen‐
257 erate .bbl files as needed, and then it is appropriate to delete
258 the bbl files in a cleanup operation since they can be re-gener‐
259 ated.
260
261 This property can also be configured by setting the $bibtex_use
262 variable to 1.5 in a configuration file.
263
264
265 -bibtexfudge, -bibtexfudge-
266 Turn on/off the change-directory fudge needed for old versions
267 (pre-2019) of bibtex. See documentation of $bibtex_fudge for
268 details.
269
270
271 -bm <message>
272 A banner message to print diagonally across each page when con‐
273 verting the dvi file to postscript. The message must be a sin‐
274 gle argument on the command line so be careful with quoting spa‐
275 ces and such.
276
277 Note that if the -bm option is specified, the -ps option is
278 assumed.
279
280
281 -bi <intensity>
282 How dark to print the banner message. A decimal number between
283 0 and 1. 0 is black and 1 is white. The default is 0.95, which
284 is OK unless your toner cartridge is getting low.
285
286
287 -bs <scale>
288 A decimal number that specifies how large the banner message
289 will be printed. Experimentation is necessary to get the right
290 scale for your message, as a rule of thumb the scale should be
291 about equal to 1100 divided by the number of characters in the
292 message. The default is 220.0 which is just right for 5 charac‐
293 ter messages.
294
295
296 -commands
297 List the commands used by latexmk for processing files, and then
298 exit.
299
300
301 -c Clean up (remove) all regeneratable files generated by latex and
302 bibtex or biber except dvi, postscript and pdf. These files are
303 a combination of log files, aux files, latexmk's database file
304 of source file information, and those with extensions specified
305 in the @generated_exts configuration variable. In addition,
306 files specified by the $clean_ext and @generated_exts configura‐
307 tion variables are removed.
308
309 This cleanup is instead of a regular make. See the -gg option
310 if you want to do a cleanup then a make.
311
312 Treatment of .bbl files: If $bibtex_use is set to 0 or 1, bbl
313 files are always treated as non-regeneratable. If $bibtex_use
314 is set to 1.5, bbl files are counted as non-regeneratable condi‐
315 tionally: If the bib file exists, then bbl files are regenerat‐
316 able, and are deleted in a clean up. But if $bibtex_use is 1.5
317 and a bib file doesn't exist, then the bbl files are treated as
318 non-regeneratable and hence are not deleted.
319
320 In contrast, if $bibtex_use is set to 2, bbl files are always
321 treated as regeneratable, and are deleted in a cleanup.
322
323 Treatment of files generated by custom dependencies: If
324 $cleanup_includes_cusdep_generated is nonzero, regeneratable
325 files are considered as including those generated by custom
326 dependencies and are also deleted. Otherwise these files are
327 not deleted.
328
329
330 -C Clean up (remove) all regeneratable files generated by latex and
331 bibtex or biber. This is the same as the -c option with the
332 addition of dvi, postscript and pdf files, and those specified
333 in the $clean_full_ext configuration variable.
334
335 This cleanup is instead of a regular make. See the -gg option
336 if you want to do a cleanup than a make.
337
338 See the -c option for the specification of whether or not .bbl
339 files are treated as non-regeneratable or regeneratable.
340
341 If $cleanup_includes_cusdep_generated is nonzero, regeneratable
342 files are considered as including those generated by custom
343 dependencies and are also deleted. Otherwise these files are
344 not deleted.
345
346
347 -CA (Obsolete). Now equivalent to the -C option. See that option
348 for details.
349
350
351 -cd Change to the directory containing the main source file before
352 processing it. Then all the generated files (.aux, .log, .dvi,
353 .pdf, etc) will be relative to the source file.
354
355 This option is particularly useful when latexmk is invoked from
356 a GUI configured to invoke latexmk with a full pathname for the
357 source file.
358
359 This option works by setting the $do_cd configuration variable
360 to one; you can set that variable if you want to configure
361 latexmk to have the effect of the -cd option without specifying
362 it on the command line. See the documentation for that vari‐
363 able.
364
365
366 -cd- Do NOT change to the directory containing the main source file
367 before processing it. Then all the generated files (.aux, .log,
368 .dvi, .pdf, etc) will be relative to the current directory
369 rather than the source file.
370
371 This is the default behavior and corresponds to the behavior of
372 the *latex programs. However, it is not desirable behavior when
373 latexmk is invoked by a GUI configured to invoke latexmk with a
374 full pathname for the source file. See the -cd option.
375
376 This option works by setting the $do_cd configuration variable
377 to zero. See the documentation for that variable for more
378 information.
379
380
381 -CF Remove the file containing the database of source file informa‐
382 tion, before doing the other actions requested.
383
384
385 -d Set draft mode. This prints the banner message "DRAFT" across
386 your page when converting the dvi file to postscript. Size and
387 intensity can be modified with the -bs and -bi options. The -bm
388 option will override this option as this is really just a short
389 way of specifying:
390
391 latexmk -bm DRAFT
392
393 Note that if the -d option is specified, the -ps option is
394 assumed.
395
396
397 -deps Show a list of dependent files after processing. This is in the
398 form of a dependency list of the form used by the make program,
399 and it is therefore suitable for use in a Makefile. It gives an
400 overall view of the files without listing intermediate files, as
401 well as latexmk can determine them.
402
403 By default the list of dependent files is sent to stdout (i.e.,
404 normally to the screen unless you've redirected latexmk's out‐
405 put). But you can set the filename where the list is sent by the
406 -deps-out= option.
407
408 See the section "USING latexmk WITH make" for an example of how
409 to use a dependency list with make.
410
411 Users familiar with GNU automake and gcc will find that the
412 -deps option is very similar in its purpose and results to the
413 -M option to gcc. (In fact, latexmk also has options -M, -MF,
414 and -MP options that behave like those of gcc.)
415
416
417 -dependents
418 Equivalent to -deps.
419
420
421 -deps- Do not show a list of dependent files after processing. (This
422 is the default.)
423
424
425 -dependents-
426 Equivalent to -deps-.
427
428
429 -deps-out=FILENAME
430 Set the filename to which the list of dependent files is writ‐
431 ten. If the FILENAME argument is omitted or set to "-", then
432 the output is sent to stdout.
433
434 Use of this option also turns on the output of the list of
435 dependent files after processing.
436
437
438 -dF Dvi file filtering. The argument to this option is a filter
439 which will generate a filtered dvi file with the extension
440 ".dviF". All extra processing (e.g. conversion to postscript,
441 preview, printing) will then be performed on this filtered dvi
442 file.
443
444 Example usage: To use dviselect to select only the even pages of
445 the dvi file:
446
447 latexmk -dF "dviselect even" foo.tex
448
449
450 -diagnostics
451 Print detailed diagnostics during a run. This may help for
452 debugging problems or to understand latexmk's behavior in diffi‐
453 cult situations.
454
455
456 -dvi Generate dvi version of document.
457
458
459 -dvi- Turn off generation of dvi version of document. (This may get
460 overridden, if some other file is made (e.g., a .ps file) that
461 is generated from the dvi file, or if no generated file at all
462 is requested.)
463
464
465 -e <code>
466 Execute the specified initialization code before processing.
467 The code is Perl code of the same form as is used in latexmk's
468 initialization files. For more details, see the information on
469 the -r option, and the section about "Configuration/initializa‐
470 tion (RC) files". The code is typically a sequence of assign‐
471 ment statements separated by semicolons.
472
473 The code is executed when the -e option is encountered during
474 latexmk's parsing of its command line. See the -r option for a
475 way of executing initialization code from a file. An error
476 results in latexmk stopping. Multiple instances of the -r and
477 -e options can be used, and they are executed in the order they
478 appear on the command line.
479
480 Some care is needed to deal with proper quoting of special char‐
481 acters in the code on the command line. For example, suppose
482 you want to set the latex command to use its -shell-escape
483 option, then under UNIX/Linux you could use the line
484
485 latexmk -e '$latex=q/latex %O -shell-escape %S/' file.tex
486
487 Note that the single quotes block normal UNIX/Linux command
488 shells from treating the characters inside the quotes as spe‐
489 cial. (In this example, the q/.../ construct is a Perl idiom
490 equivalent to using single quotes. This avoids the complica‐
491 tions of getting a quote character inside an already quoted
492 string in a way that is independent of both the shell and the
493 operating-system.)
494
495 The above command line will NOT work under MS-Windows with
496 cmd.exe or command.com or 4nt.exe. For MS-Windows with these
497 command shells you could use
498
499 latexmk -e "$latex=q/latex %O -shell-escape %S/" file.tex
500
501 or
502
503 latexmk -e "$latex='latex %O -shell-escape %S'" file.tex
504
505 The last two examples will NOT work with UNIX/Linux command
506 shells.
507
508 (Note: the above examples show are to show how to use the -e to
509 specify initialization code to be executed. But the particular
510 effect can be achieved also by the use of the -latex option with
511 less problems in dealing with quoting.)
512
513
514 -f Force latexmk to continue document processing despite errors.
515 Normally, when latexmk detects that LaTeX or another program has
516 found an error which will not be resolved by further processing,
517 no further processing is carried out.
518
519 Note: "Further processing" means the running of other programs
520 or the rerunning of latex (etc) that would be done if no errors
521 had occurred. If instead, or additionally, you want the latex
522 (etc) program not to pause for user input after an error, you
523 should arrange this by an option that is passed to the program,
524 e.g., by latexmk's option -interaction=nonstopmode.
525
526
527 -f- Turn off the forced processing-past-errors such as is set by the
528 -f option. This could be used to override a setting in a con‐
529 figuration file.
530
531
532 -g Force latexmk to process document fully, even under situations
533 where latexmk would normally decide that no changes in the
534 source files have occurred since the previous run. This option
535 is useful, for example, if you change some options and wish to
536 reprocess the files.
537
538
539 -g- Turn off -g.
540
541
542 -gg "Super go mode" or "clean make": clean out generated files as if
543 -C had been given, and then do a regular make.
544
545
546 -h, -help
547 Print help information.
548
549
550 -jobname=STRING
551 Set the basename of output files(s) to STRING, instead of the
552 default, which is the basename of the specified TeX file. (At
553 present, STRING should not contain spaces.)
554
555 This is like the same option for current implementations of the
556 *latex, and the passing of this option to these programs is part
557 of latexmk's implementation of -jobname.
558
559 There is one enhancement, that the STRING may contain the place‐
560 holder '%A'. This will be substituted by the basename of the TeX
561 file. The primary purpose is when multiple files are specified
562 on the command line to latexmk, and you wish to use a jobname
563 with a different file-dependent value for each file. For exam‐
564 ple, suppose you had .tex files test1.tex and test2.tex, and you
565 wished to compare the results of compilation by *latex and those
566 with xelatex. Then under a unix-type operating system you could
567 use the command line
568
569 latexmk -pdf -jobname=%A-pdflatex *.tex
570 latexmk -pdfxe -jobname=%A-xelatex *.tex
571
572 Then the .aux, .log, and .pdf files from the use of pdflatex
573 would have basenames test1-pdflatex and test2-pdflatex, while
574 from xelatex, the basenames would be test1-xelatex and
575 test2-xelatex.
576
577 Under MS-Windows with cmd.exe, you would need to double the per‐
578 cent sign, so that the percent character is passed to latexmk
579 rather than being used to substitute an environment variable:
580
581 latexmk -pdf -jobname=%%A-pdflatex *.tex
582 latexmk -pdfxe -jobname=%%A-xelatex *.tex
583
584
585 -l Run in landscape mode, using the landscape mode for the preview‐
586 ers and the dvi to postscript converters. This option is not
587 normally needed nowadays, since current previewers normally
588 determine this information automatically.
589
590
591 -l- Turn off -l.
592
593
594 -latex This sets the generation of dvi files by latex, and turns off
595 the generation of pdf and ps files.
596
597 Note: to set the command used when latex is specified, see the
598 -latex="COMMAND" option.
599
600
601 -latex="COMMAND"
602 This sets the string specifying the command to run latex, and is
603 typically used to add desired options. Since the string nor‐
604 mally contains spaces, it should be quoted, e.g.,
605
606 latexmk -latex="latex --shell-escape %O %S" foo.tex
607
608 The specification of the contents of the string are the same as
609 for the $latex configuration variable. Depending on your oper‐
610 ating system and the command-line shell you are using, you may
611 need to change the single quotes to double quotes (or something
612 else).
613
614 Note: This option when provided with the COMMAND argument only
615 sets the command for invoking latex; it does not turn on the use
616 of latex. That is done by other options or in an initialization
617 file.
618
619 To set the command for running pdflatex (rather than the command
620 for latex) see the -pdflatex option.
621
622
623 -logfilewarninglist
624 -logfilewarnings After a run of *latex, give a list of warnings
625 about undefined citations and references (unless silent mode is
626 on).
627
628 See also the $silence_logfile_warnings configuration variable.
629
630
631 -logfilewarninglist-
632 -logfilewarnings- After a run of *latex, do not give a list of
633 warnings about undefined citations and references. (Default)
634
635 See also the $silence_logfile_warnings configuration variable.
636
637
638 -lualatex
639 Use lualatex. That is, use lualatex to process the source
640 file(s) to pdf. The generation of dvi and postscript files is
641 turned off.
642
643 This option is equivalent to using the following set of options
644
645 -pdflua -dvi- -ps-
646
647 (Note: Note that the method of implementation of this option,
648 but not its intended effect, differ from some earlier versions
649 of latexmk.)
650
651
652 -lualatex="COMMAND"
653 This sets the string specifying the command to run lualatex. It
654 behaves like the -pdflatex option, but sets the variable $luala‐
655 tex.
656
657 Note: This option when provided with the COMMAND argument only
658 sets the command for invoking lualatex; it does not turn on the
659 use of lualatex. That is done by other options or in an initial‐
660 ization file.
661
662
663 -M Show list of dependent files after processing. This is equiva‐
664 lent to the -deps option.
665
666
667 -MF file
668 If a list of dependents is made, the -MF specifies the file to
669 write it to.
670
671
672 -MP If a list of dependents is made, include a phony target for each
673 source file. If you use the dependents list in a Makefile, the
674 dummy rules work around errors the program make gives if you
675 remove header files without updating the Makefile to match.
676
677
678 -MSWinBackSlash
679 This option only has an effect when latexmk is running under MS-
680 Windows. This is that when latexmk runs a command under MS-Win‐
681 dows, the Windows standard directory separator "\" is used to
682 separate directory components in a file name. Internally,
683 latexmk uses "/" for the directory separator character, which is
684 the character used by Unix-like systems.
685
686 This is the default behavior. However the default may have been
687 overridden by a configuration file (latexmkrc file) which sets
688 $MSWin_back_slash=0.
689
690
691 -MSWinBackSlash-
692 This option only has an effect when latexmk is running under MS-
693 Windows. This is that when latexmk runs a command under MS-Win‐
694 dows, the substitution of "\" for the separator character
695 between directory components of a file name is not done. Instead
696 the forward slash "/" is used, the same as on Unix-like systems.
697 This is acceptable in most situations under MS-Windows, provided
698 that filenames are properly quoted, as latexmk does by default.
699
700 See the documentation for the configuration variable
701 $MSWin_back_slash for more details.
702
703
704 -new-viewer
705 When in continuous-preview mode, always start a new viewer to
706 view the generated file. By default, latexmk will, in continu‐
707 ous-preview mode, test for a previously running previewer for
708 the same file and not start a new one if a previous previewer is
709 running. However, its test sometimes fails (notably if there is
710 an already-running previewer that is viewing a file of the same
711 name as the current file, but in a different directory). This
712 option turns off the default behavior.
713
714
715 -new-viewer-
716 The inverse of the -new-viewer option. It puts latexmk in its
717 normal behavior that in preview-continuous mode it checks for an
718 already-running previewer.
719
720
721 -nobibtex
722 Never run bibtex or biber. Equivalent to the -bibtex- option.
723
724
725 -nobibtexfudge
726 Turn off the change-directory fudge needed for old versions
727 (pre-2019) of bibtex. See documentation of $bibtex_fudge for
728 details.
729
730
731 -norc Turn off the automatic reading of initialization (rc) files.
732
733 N.B. Normally the initialization files are read and obeyed, and
734 then command line options are obeyed in the order they are
735 encountered. But -norc is an exception to this rule: it is
736 acted on first, no matter where it occurs on the command line.
737
738
739 -outdir=FOO or -output-directory=FOO
740
741 Sets the directory for the output files of *latex. This
742 achieves its effect by the -output-directory option of *latex,
743 which currently (Dec. 2011 and later) is implemented on the com‐
744 mon versions of *latex, i.e., MiKTeX and TeXLive. It may not be
745 present in other versions.
746
747 See also the -auxdir/-aux-directory options, and the $aux_dir,
748 $out_dir, and $search_path_separator configuration variables of
749 latexmk. In particular, see the documentation of $out_dir for
750 some complications on what directory names are suitable.
751
752 If you also use the -cd option, and the specified output direc‐
753 tory is a relative path, then the path is interpreted relative
754 to the document directory.
755
756
757 -p Print out the document. By default the file to be printed is
758 the first in the list postscript, pdf, dvi that is being made.
759 But you can use the -print=... option to change the type of file
760 to be printed, and you can configure this in a start up file (by
761 setting the $print_type variable).
762
763 However, printing is enabled by default only under UNIX/Linux
764 systems, where the default is to use the lpr command and only on
765 postscript files. In general, the correct behavior for printing
766 very much depends on your system's software. In particular,
767 under MS-Windows you must have suitable program(s) available,
768 and you must have configured the print commands used by latexmk.
769 This can be non-trivial. See the documentation on the $lpr,
770 $lpr_dvi, and $lpr_pdf configuration variables to see how to set
771 the commands for printing.
772
773 This option is incompatible with the -pv and -pvc options, so it
774 turns them off.
775
776
777 -pdf Generate pdf version of document using pdflatex. (If you wish
778 to use lualatex or xelatex, you can use whichever of the options
779 -pdflua, -pdfxe, -lualatex or -xelatex applies.) To configure
780 latexmk to have such behavior by default, see the section on
781 "Configuration/initialization (rc) files".
782
783
784 -pdfdvi
785 Generate pdf version of document from the dvi file, by default
786 using dvipdf.
787
788
789 -pdflua
790 Generate pdf version of document using lualatex.
791
792
793 -pdfps Generate pdf version of document from the .ps file, by default
794 using ps2pdf.
795
796
797 -pdfxe Generate pdf version of document using xelatex. Note that to
798 optimize processing time, latexmk uses xelatex to generate an
799 .xdv file rather than a pdf file directly. Only after possibly
800 multiple runs to generate a fully up-to-date .xdv file does
801 latexmk then call xdvipdfmx to generate the final .pdf file.
802
803 (Note: The reason why latexmk arranges for xelatex to make an
804 .xdv file instead of the xelatex's default of a .pdf file is as
805 follows: When the document includes large graphics files, espe‐
806 cially .png files, the production of a .pdf file can be quite
807 time consuming, even when the creation of the .xdv file by xela‐
808 tex is fast. So the use of the intermediate .xdv file can
809 result in substantial gains in procesing time, since the .pdf
810 file is produced once rather than on every run of xelatex.)
811
812
813 -pdf- Turn off generation of pdf version of document. (This can be
814 used to override a setting in a configuration file. It may get
815 overridden if some other option requires the generation of a pdf
816 file.)
817
818 If after all options have been processed, pdf generation is
819 still turned off, then generation of a dvi file will be turned
820 on, and then the program used to compiled a document will be
821 latex (or, more precisely, whatever program is configured to be
822 used in the $latex configuration variable).
823
824
825 -pdflatex
826 This sets the generation of pdf files by pdflatex, and turns off
827 the generation of dvi and ps files.
828
829 Note: to set the command used when pdflatex is specified, see
830 the -pdflatex="COMMAND" option.
831
832
833 -pdflatex="COMMAND"
834 This sets the string specifying the command to run pdflatex, and
835 is typically used to add desired options. Since the string nor‐
836 mally contains spaces, it should be quoted, e.g.,
837
838 latexmk -pdf -pdflatex="pdflatex --shell-escape %O %S"
839 foo.tex
840
841 The specification of the contents of the string are the same as
842 for the $pdflatex configuration variable. (The option -pdflatex
843 in fact sets the variable $pdflatex.) Depending on your operat‐
844 ing system and the command-line shell you are using, you may
845 need to change the single quotes to double quotes (or something
846 else).
847
848 Note: This option when provided with the COMMAND argument only
849 sets the command for invoking pdflatex; it does not turn on the
850 use of pdflatex. That is done by other options or in an initial‐
851 ization file.
852
853 To set the command for running latex (rather than the command
854 for pdflatex) see the -latex option.
855
856
857 -pdflualatex="COMMAND"
858 Equivalent to -lualatex="COMMAND".
859
860
861 -pdfxelatex="COMMAND"
862 Equivalent to -xelatex="COMMAND".
863
864
865 -pretex=CODE
866
867 Given that CODE is some TeX code, this options sets that code to
868 be executed before inputting source file. This only works if
869 the command for invoking the relevant *latex is suitably config‐
870 ured. See the documentation of the variable $pre_tex_code, and
871 the substitution strings %P and %U for more details. This
872 option works by setting the variable $pre_tex_code.
873
874 See also the -usepretex option.
875
876 An example:
877
878 latexmk -pretex='\AtBeginDocument{Message\par}' -usepretex
879 foo.tex
880
881 But this is better written
882
883 latexmk -usepretex='\AtBeginDocument{Message\par}' foo.tex
884
885 If you already have a suitable command configured, you only need
886
887 latexmk -pretex='\AtBeginDocument{Message\par}' foo.tex
888
889
890 -print=dvi, -print=ps, -print=pdf, -print=auto,
891 Define which kind of file is printed. This option also ensures
892 that the requisite file is made, and turns on printing.
893
894 The (default) case -print=auto determines the kind of print file
895 automatically from the set of files that is being made. The
896 first in the list postscript, pdf, dvi that is among the files
897 to be made is the one used for print out.
898
899
900 -ps Generate postscript version of document.
901
902
903 -ps- Turn off generation of postscript version of document. This can
904 be used to override a setting in a configuration file. (It may
905 get overridden by some other option that requires a postscript
906 file, for example a request for printing.)
907
908
909 -pF Postscript file filtering. The argument to this option is a
910 filter which will generate a filtered postscript file with the
911 extension ".psF". All extra processing (e.g. preview, printing)
912 will then be performed on this filtered postscript file.
913
914 Example of usage: Use psnup to print two pages on the one page:
915
916 latexmk -ps -pF 'psnup -2' foo.tex
917
918 or
919
920 latexmk -ps -pF "psnup -2" foo.tex
921
922 Whether to use single or double quotes round the "psnup -2" will
923 depend on your command interpreter, as used by the particular
924 version of perl and the operating system on your computer.
925
926
927 -pv Run file previewer. If the -view option is used, this will
928 select the kind of file to be previewed (.dvi, .ps or .pdf).
929 Otherwise the viewer views the "highest" kind of file selected,
930 by the -dvi, -ps, -pdf, -pdfps options, in the order .dvi, .ps,
931 .pdf (low to high). If no file type has been selected, the dvi
932 previewer will be used. This option is incompatible with the -p
933 and -pvc options, so it turns them off.
934
935
936 -pv- Turn off -pv.
937
938
939 -pvc Run a file previewer and continually update the .dvi, .ps,
940 and/or .pdf files whenever changes are made to source files (see
941 the Description above). Which of these files is generated and
942 which is viewed is governed by the other options, and is the
943 same as for the -pv option. The preview-continuous option -pvc
944 can only work with one file. So in this case you will normally
945 only specify one filename on the command line. It is also
946 incompatible with the -p and -pv options, so it turns these
947 options off.
948
949 The -pvc option also turns off force mode (-f), as is normally
950 best for continuous preview mode. If you really want force
951 mode, use the options in the order -pvc -f.
952
953 With a good previewer the display will be automatically updated.
954 (Under some but not all versions of UNIX/Linux "gv -watch" does
955 this for postscript files; this can be set by a configuration
956 variable. This would also work for pdf files except for an
957 apparent bug in gv that causes an error when the newly updated
958 pdf file is read.) Many other previewers will need a manual
959 update.
960
961 Important note: the acroread program on MS-Windows locks the pdf
962 file, and prevents new versions being written, so it is a bad
963 idea to use acroread to view pdf files in preview-continuous
964 mode. It is better to use a different viewer: SumatraPDF and
965 gsview are good possibilities.
966
967 There are some other methods for arranging an update, notably
968 useful for many versions of xdvi and xpdf. These are best set
969 in latexmk's configuration; see below.
970
971 Note that if latexmk dies or is stopped by the user, the
972 "forked" previewer will continue to run. Successive invocations
973 with the -pvc option will not fork new previewers, but latexmk
974 will normally use the existing previewer. (At least this will
975 happen when latexmk is running under an operating system where
976 it knows how to determine whether an existing previewer is run‐
977 ning.)
978
979
980 -pvc- Turn off -pvc.
981
982
983 -pvctimeout
984 Do timeout in pvc mode after period of inactivity, which is 30
985 min. by default. Inactivity means a period when latexmk has
986 detected no file changes and hence has not taken any actions
987 like compiling the document.
988
989
990 -pvctimeout-
991 Don't do timeout in pvc mode after inactivity.
992
993
994 -pvctimeoutmins=<time>
995 Set period of inactivity in minutes for pvc timeout.
996
997
998 -quiet Same as -silent
999
1000
1001 -r <rcfile>
1002 Read the specified initialization file ("RC file") before pro‐
1003 cessing.
1004
1005 Be careful about the ordering: (1) Standard initialization files
1006 -- see the section below on "Configuration/initialization (RC)
1007 files" -- are read first. (2) Then the options on the command
1008 line are acted on in the order they are given. Therefore if an
1009 initialization file is specified by the -r option, it is read
1010 during this second step. Thus an initialization file specified
1011 with the -r option can override both the standard initialization
1012 files and previously specified options. But all of these can be
1013 overridden by later options.
1014
1015 The contents of the RC file just comprise a piece of code in the
1016 Perl programming language (typically a sequence of assignment
1017 statements); they are executed when the -r option is encountered
1018 during latexmk's parsing of its command line. See the -e option
1019 for a way of giving initialization code directly on latexmk's
1020 command line. An error results in latexmk stopping. Multiple
1021 instances of the -r and -e options can be used, and they are
1022 executed in the order they appear on the command line.
1023
1024
1025 -recorder
1026 Give the -recorder option with *latex. In (most) modern ver‐
1027 sions of these programs, this results in a file of extension
1028 .fls containing a list of the files that these programs have
1029 read and written. Latexmk will then use this file to improve
1030 its detection of source files and generated files after a run of
1031 *latex. This is the default setting of latexmk, unless overrid‐
1032 den in an initialization file.
1033
1034 For further information, see the documentation for the $recorder
1035 configuration variable.
1036
1037
1038 -recorder-
1039 Do not supply the -recorder option with *latex.
1040
1041
1042 -rules Show a list of latemk's rules and dependencies after processing.
1043
1044
1045 -rules-
1046 Do not show a list of latexmk's rules and dependencies after
1047 processing. (This is the default.)
1048
1049
1050 -showextraoptions
1051 Show the list of extra *latex options that latexmk recognizes,
1052 but that it simply passes through to the programs *latex when
1053 they are run. These options are (currently) a combination of
1054 those allowed by the TeXLive and MiKTeX implementations. (If a
1055 particular option is given to latexmk but is not handled by the
1056 particular implementation of *latex that is being used, that
1057 program will probably give an error message.) These options are
1058 very numerous, but are not listed in this documentation because
1059 they have no effect on latexmk's actions.
1060
1061 There are a few options (-includedirectory=dir, -initialize,
1062 -ini) that are not recognized, either because they don't fit
1063 with latexmk's intended operations, or because they need special
1064 processing by latexmk that isn't implemented (at least, not
1065 yet).
1066
1067 There are also options that are accepted by latex etc, but
1068 instead trigger actions by latexmk: -help, -version.
1069
1070 Finally, there are certain options for *latex (e.g., -recorder)
1071 that trigger special actions or behavior by latexmk itself as
1072 well as being passed in some form to the called *latex program,
1073 or that affect other programs as well. These options do have
1074 entries in this documentation. These options are: -job‐
1075 name=STRING, -aux-directory=dir, -output-directory=DIR, -quiet,
1076 and -recorder.
1077
1078
1079 -silent
1080 Run commands silently, i.e., with options that reduce the amount
1081 of diagnostics generated. For example, with the default set‐
1082 tings, the command "latex -interaction=batchmode" is used for
1083 latex, and similarly for its friends.
1084
1085 See also the -logfilewarninglist and -logfilewarninglist-
1086 options.
1087
1088 Also reduce the number of informational messages that latexmk
1089 itself generates.
1090
1091 To change the options used to make the commands run silently,
1092 you need to configure latexmk with changed values of its config‐
1093 uration variables, the relevant ones being $bib‐
1094 tex_silent_switch, $biber_silent_switch, $dvipdf_silent_switch,
1095 $dvips_silent_switch, $latex_silent_switch, $luala‐
1096 tex_silent_switch $makeindex_silent_switch, $pdfla‐
1097 tex_silent_switch, and $xelatex_silent_switch
1098
1099
1100 -stdtexcmds
1101 Sets the commands for latex, etc, so that they are the standard
1102 ones. This is useful to override special configurations.
1103
1104 The result is that $latex = 'latex %O %S', and similarly for
1105 $pdflatex, $lualatex, and $xelatex. (The option -no-pdf needed
1106 for $xelatex is provided automatically, given that %O appears in
1107 the definition.)
1108
1109
1110 -time Show CPU time used. See also the configuration variable
1111 $show_time.
1112
1113
1114 -time- Do not show CPU time used. See also the configuration variable
1115 $show_time.

1117
1118 -use-make
1119 When after a run of *latex, there are warnings about missing
1120 files (e.g., as requested by the LaTeX \input, \include, and
1121 \includgraphics commands), latexmk tries to make them by a cus‐
1122 tom dependency. If no relevant custom dependency with an appro‐
1123 priate source file is found, and if the -use-make option is set,
1124 then as a last resort latexmk will try to use the make program
1125 to try to make the missing files.
1126
1127 Note that the filename may be specified without an extension,
1128 e.g., by \includegraphics{drawing} in a LaTeX file. In that
1129 case, latexmk will try making drawing.ext with ext set in turn
1130 to the possible extensions that are relevant for latex (or as
1131 appropriate pdflatex, lualatex, xelatex).
1132
1133 See also the documentation for the $use_make_for_missing_files
1134 configuration variable.
1135
1136
1137 -use-make-
1138 Do not use the make program to try to make missing files.
1139 (Default.)
1140
1141
1142 -usepretex
1143 Sets the command lines for latex, etc, so that they use the code
1144 that is defined by the variable $pre_tex_code or that is set by
1145 the option -pretex=CODE to execute the specified TeX code before
1146 the source file is read. This option overrides any previous
1147 definition of the command lines.
1148
1149 The result is that $latex = 'latex %O %P', and similarly for
1150 $pdflatex, $lualatex, and $xelatex. (The option -no-pdf needed
1151 for $xelatex is provided automatically, given that %O appears in
1152 the definition.)
1153
1154
1155 -usepretex=CODE
1156 Equivalent to -pretex=CODE -usepretex. Example
1157
1158 latexmk -usepretex='\AtBeginDocument{Message\par}' foo.tex
1159
1160
1161 -v, -version
1162 Print version number of latexmk.
1163
1164
1165 -verbose
1166 Opposite of -silent. This is the default setting.
1167
1168
1169 -view=default, -view=dvi, -view=ps, -view=pdf, -view=none
1170 Set the kind of file used when previewing is requested (e.g., by
1171 the -pv or -pvc switches). The default is to view the "highest"
1172 kind of requested file (in the low-to-high order .dvi, .ps,
1173 .pdf).
1174
1175 Note the possibility -view=none where no viewer is opened at
1176 all. One example of is use is in conjunction with the -pvc
1177 option, when you want latexmk to do a compilation automatically
1178 whenever source file(s) change, but do not want a previewer to
1179 be opened.
1180
1181
1182 -Werror
1183 This causes latexmk to return a non-zero status code if any of
1184 the files processed gives a warning about problems with cita‐
1185 tions or references (i.e., undefined citations or references or
1186 about multiply defined references). This is after latexmk has
1187 completed all the runs it needs to try and resolve references
1188 and citations. Thus -Werror causes latexmk to treat such warn‐
1189 ings as errors, but only when they occur on the last run of
1190 *latex and only after processing is complete. Also can be set
1191 by the configuration variable $warnings_as_errors.
1192
1193
1194 -xelatex
1195 Use xelatex. That is, use xelatex to process the source file(s)
1196 to pdf. The generation of dvi and postscript files is turned
1197 off.
1198
1199 This option is equivalent to using the following set of options
1200
1201 -pdfxe -dvi- -ps-
1202
1203 [Note: Note that the method of implementation of this option,
1204 but not its intended primary effect, differ from some earlier
1205 versions of latexmk. Latexmk first uses xelatex to make an .xdv
1206 file, and does all the extra runs needed (including those of
1207 bibtex, etc). Only after that does it make the pdf file from
1208 the .xdv file, using xdvipdfmx. See the documentation for the
1209 -pdfxe for why this is done.]
1210
1211
1212 -xelatex="COMMAND"
1213 This sets the string specifying the command to run xelatex. It
1214 sets the variable $xelatex.
1215
1216 Warning: It is important to ensure that the -no-pdf is used when
1217 xelatex is invoked, since latexmk expects xelatex to produce an
1218 .xdv file, not a .pdf file. If you provide %O in the command
1219 specification, this will be done automatically. See the docu‐
1220 mentation for the -pdfxe option for why latexmk makes a .xdv
1221 file rather than a .pdf file when xelatex is used.
1222
1223 An example of the use of the -pdfxelatex option:
1224
1225 latexmk -pdfxe -pdfxelatex="xelatex --shell-escape %O %S"
1226 foo.tex
1227
1228 Note: This option when provided with the COMMAND argument only
1229 sets the command for invoking lualatex; it does not turn on the
1230 use of lualatex. That is done by other options or in an initial‐
1231 ization file.
1232
1233
1234 Compatibility between options
1235
1236 The preview-continuous option -pvc can only work with one file. So in
1237 this case you will normally only specify one filename on the command
1238 line.
1239
1240 Options -p, -pv and -pvc are mutually exclusive. So each of these
1241 options turns the others off.
1242
1243
1245 % latexmk thesis # run latex enough times to resolve
1246 cross-references
1247
1248 % latexmk -pvc -ps thesis# run latex enough times to resolve
1249 cross-references, make a postscript
1250 file, start a previewer. Then
1251 watch for changes in the source
1252 file thesis.tex and any files it
1253 uses. After any changes rerun latex
1254 the appropriate number of times and
1255 remake the postscript file. If latex
1256 encounters an error, latexmk will
1257 keep running, watching for
1258 source file changes.
1259
1260 % latexmk -c # remove .aux, .log, .bbl, .blg, .dvi,
1261 .pdf, .ps & .bbl files
1262
1263
1264
1266 Some possibilities:
1267
1268 a. If you get a strange error, do look carefully at the output that is
1269 on the screen and in log files. While there is much that is notori‐
1270 ously verbose in the output of latex (and that is added to by latexmk),
1271 the verbosity is there for a reason: to enable the user to diagnose
1272 problems. Latexmk does repeat some messages at the end of a run that
1273 it thinks would otherwise be easy to miss in the middle of other out‐
1274 put.
1275
1276 b. Generally, remember that latexmk does its work by running other pro‐
1277 grams. Your first priority in dealing with errors should be to examine
1278 what went wrong with the individual programs. Then you need to correct
1279 the causes of errors in the runs of these programs. (Often these come
1280 from errors in the source document, but they could also be about miss‐
1281 ing LaTeX packages, etc.)
1282
1283 c. If latexmk doesn't run the programs the way you would like, then you
1284 need to look in this documentation at the list of command line options
1285 and then at the sections on configuration/initialization files. A lot
1286 of latexmk's behavior is configurable to deal with particular situa‐
1287 tions. (But there is a lot of reading!)
1288
1289 The remainder of these notes consists of ideas for dealing with more
1290 difficult situations.
1291
1292 d. Further tricks can involve replacing the standard commands that
1293 latexmk runs by other commands or scripts.
1294
1295 e. For possible examples of code for use in an RC file, see the direc‐
1296 tory example_rcfiles in the distribution of latexmk (e.g., at
1297 http://mirror.ctan.org/support/latexmk/example_rcfiles). Even if these
1298 examples don't do what you want, they may provide suitable inspiration.
1299
1300 f. There's a useful trick that can be used when you use lualatex
1301 instead of pdflatex (and in some related situations). The problem is
1302 that latexmk won't notice a dependency on a file, bar.baz say, that is
1303 input by the lua code in your document instead of by the LaTeX part.
1304 (Thus if you change bar.baz and rerun latexmk, then latexmk will think
1305 no files have changed and not rerun lualatex, whereas if you had
1306 '\input{bar.baz}' in the LaTeX part of the document, latexmk would
1307 notice the change.) One solution is just to put the following some‐
1308 where in the LaTeX part of the document:
1309
1310 \typeout{(bar.baz)}
1311
1312 This puts a line in the log file that latexmk will treat as implying
1313 that the file bar.baz was read. (At present I don't know a way of
1314 doing this automatically.) Of course, if the file has a different
1315 name, change bar.baz to the name of your file.

1319 h. Look on tex.stackexchange, i.e., at http://tex.stackex‐

1321 your problem.

1325 j. Or ask me (the author of latexmk). My e-mail is at the end of this
1326 documentation.
1327
1328
1329
1331 When one of the latex engines is run, the usual situation is that latex
1332 produces a .dvi file, while pdflatex and lualatex produce a .pdf file.
1333 For xelatex the default is to produce a .pdf file, but to optimize pro‐
1334 cessing time latexmk runs xelatex its -no-pdf option so that it pro‐
1335 duces an .xdv file. Further processing by latexmk takes this as a
1336 starting point.
1337
1338 However, the actual output file may differ from the normal expectation;
1339 and then latexmk can adjust its processing to accommodate this situa‐
1340 tion. The difference in output file type can happen for two reasons:
1341 One is that for latex, pdflatex and lualatex the document itself can
1342 override the defaults. The other is that there may be a configuration,
1343 or misconfiguration, such that the program that latexmk invokes to com‐
1344 pile the document is not the expected one, or is given options incom‐
1345 patible with what latexmk initially expects. (E.g., the -output-for‐
1346 mat=... option could be used with lualatex, or xelatex gets invoked
1347 without the -no-pdf option.)
1348
1349 Under latex and pdflatex, control of the output format by the document
1350 is done by setting the \pdfoutput macro. Under lualatex, the \output‐
1351 mode macro is used instead.
1352
1353 One example of an important use-case for document control of the output
1354 format is a document that uses the psfrag package to insert graphical
1355 elements in the output file. The psfrag package achieves its effects by
1356 inserting postscript code in the output of the compilation of the docu‐
1357 ment. This entails the use of compilation to a .dvi file, followed by
1358 the use of conversion to a postscript file (either directly, as by
1359 dvips or implicitly, as an intermediate step by dvipdf). Then it is
1360 useful to force output to be of the .dvi format by inserting \pdfout‐
1361 put=0 in the preamble of the document.
1362
1363 Another example is where the document uses graphics file of the .pdf,
1364 .jpg, and png types. With the default setting for the graphicx pack‐
1365 age, these can be processed in compilation to .pdf but not with compi‐
1366 lation to .dvi. In this case, it is useful to insert \pdfoutput=1 in
1367 the preamble of the document to force compilation to .pdf output for‐
1368 mat.
1369
1370 In all of these cases, it is needed that latexmk has to adjust its pro‐
1371 cessing to deal with a mismatch between the actual output format (out
1372 of .pdf, .dvi, .xdv) and the initially expected output, if possible.
1373 Latexmk does this provided the following conditions are met.
1374
1375 The first is that latexmk's $allow_switch configuration variable is set
1376 to a non-zero value as it is by default. If this variable is zero, a
1377 mismatch of filetypes in the compilation results in an erro.
1378
1379 The second condition for latexmk to be able to handle a change of out‐
1380 put type is that no explicit requests for .dvi or .ps output files are
1381 made. Explicit requests are by the -dvi and -ps, -print=dvi,
1382 -print=ps, -view=dvi, and -view=ps options, and by corresponding set‐
1383 tings of the $dvi_mode, $postscript_mode, $print_type, and $view con‐
1384 figuration variables. The print-type and view-type restrictions only
1385 apply when printing and viewing are explicitly requested, respectively.
1386 For this purpose, the use of the -pdfdvi and -pdfps options (and the
1387 corresponding setting of the $pdf_mode variable) does not count as an
1388 explicit request for the .dvi and .ps files; they are merely regarded
1389 as a request for making a .pdf file together with an initial proposal
1390 for the processing route to make it.
1391
1392 Note that when accommodating a change in output file type, there is
1393 involved a substantial change in the network of rules that latexmk uses
1394 in its actions. The second condition applied to accommodate a change
1395 is to avoid situations where the change in the rule network is too rad‐
1396 ical to be readily handled automatically.
1397
1398
1399
1401 In this section is explained which configuration files are read by
1402 latexmk. Subsequent sections "How to Set Variables in Initialization
1403 Files", "Format of Command Specifications", "List of Configuration
1404 Variables Usable in Initialization Files", "Custom Dependencies", and
1405 "Advanced Configuration" give details on what can be configured and
1406 how.
1407
1408 Latexmk can be customized using initialization files, which are read at
1409 startup in the following order:
1410
1411 1) The system RC file, if it exists.
1412 On a UNIX system, latexmk searches for following places for its sys‐
1413 tem RC file, in the following order, and reads the first it finds:
1414 "/opt/local/share/latexmk/LatexMk",
1415 "/usr/local/share/latexmk/LatexMk",
1416 "/usr/local/lib/latexmk/LatexMk".
1417 On a Fedora system, it only looks for "/etc/latexmk.conf".
1418 On a MS-Windows system it looks for "C:\latexmk\LatexMk".
1419 On a cygwin system (i.e., a MS-Windows system in which Perl is that
1420 of cygwin), latexmk reads the first it finds of
1421 "/cygdrive/c/latexmk/LatexMk",
1422 "/opt/local/share/latexmk/LatexMk",
1423 "/usr/local/share/latexmk/LatexMk",
1424 "/usr/local/lib/latexmk/LatexMk".
1425
1426 In addition, it then tries the same set of locations, but with the file
1427 name replaced "LatexMk" replaced by "latexmkrc".
1428
1429 If the environment variable LATEXMKRCSYS is set, its value is used as
1430 the name of the system RC file, instead of any of the above.
1431
1432 2) The user's RC file, if it exists. This can be in one of two places.
1433 The traditional one is ".latexmkrc" in the user's home directory. The
1434 other possibility is "latexmk/latexmkrc" in the user's XDG configura‐
1435 tion home directory. The actual file read is the first of "$XDG_CON‐
1436 FIG_HOME/latexmk/latexmkrc" or "$HOME/.latexmkrc" which exists. (See
1437 https://specifications.freedesktop.org/basedir-spec/basedir-spec-lat‐
1438 est.html for details on the XDG Base Directory Specification.)
1439
1440 Here $HOME is the user's home directory. [Latexmk determines the
1441 user's home directory as follows: It is the value of the environment
1442 variable HOME, if this variable exists, which normally is the case on
1443 UNIX-like systems (including Linux and OS-X). Otherwise the environ‐
1444 ment variable USERPROFILE is used, if it exists, which normally is the
1445 case on MS-Windows systems. Otherwise a blank string is used instead of
1446 $HOME, in which case latexmk does not look for an RC file in it.]
1447
1448 $XDG_CONFIG_HOME is the value of the environment variable XDG_CON‐
1449 FIG_HOME if it exists. If this environment variable does not exist,
1450 but $HOME is non-blank, then $XDG_CONFIG_HOME is set to the default
1451 value of $HOME/.config. Otherwise $XDG_CONFIG_HOME is blank, and
1452 latexmk does not look for an RC file under it.
1453
1454
1455 3) The RC file in the current working directory. This file can be
1456 named either "latexmkrc" or ".latexmkrc", and the first of these to be
1457 found is used, if any.
1458
1459 4) Any RC file(s) specified on the command line with the -r option.
1460
1461 Each RC file is a sequence of Perl commands. Naturally, a user can use
1462 this in creative ways. But for most purposes, one simply uses a
1463 sequence of assignment statements that override some of the built-in
1464 settings of Latexmk. Straightforward cases can be handled without
1465 knowledge of the Perl language by using the examples in this document
1466 as templates. Comment lines are introduced by the "#" character.
1467
1468 Note that command line options are obeyed in the order in which they
1469 are written; thus any RC file specified on the command line with the -r
1470 option can override previous options but can be itself overridden by
1471 later options on the command line. There is also the -e option, which
1472 allows initialization code to be specified in latexmk's command line.
1473
1474 For possible examples of code for in an RC file, see the directory
1475 example_rcfiles in the distribution of latexmk (e.g., at http://mir‐
1476 ror.ctan.org/support/latexmk/example_rcfiles).
1477
1478
1480 The important variables that can be configured are described in the
1481 section "List of configuration variables usable in initialization
1482 files". (See the earlier section "Configuration/Initialization (rc)
1483 Files" for the files where the configurations are done.) Syntax for
1484 setting these variables is of the following forms:
1485
1486 $bibtex = 'bibtex %O %S';
1487
1488 for the setting of a string variable,
1489
1490 $preview_mode = 1;
1491
1492 for the setting of a numeric variable, and
1493
1494 @default_files = ('paper', 'paper1');
1495
1496 for the setting of an array of strings. It is possible to append an
1497 item to an array variable as follows:
1498
1499 push @default_files, 'paper2';
1500
1501 Note that simple "scalar" variables have names that begin with a $
1502 character and array variables have names that begin with a @ character.
1503 Each statement ends with a semicolon.
1504
1505 Strings should be enclosed in single quotes. (You could use double
1506 quotes, as in many programming languages. But then the Perl program‐
1507 ming language brings into play some special rules for interpolating
1508 variables into strings. People not fluent in Perl will want to avoid
1509 these complications.)
1510
1511 You can do much more complicated things, but for this you will need to
1512 consult a manual for the Perl programming language.
1513
1514
1515
1516
1518 Some of the variables set the commands that latexmk uses for carrying
1519 out its work, for example to generate a .dvi file from a .tex file or
1520 to view a postscript file. This section describes some important fea‐
1521 tures of how the commands are specified. (Note that some of the possi‐
1522 bilities listed here do not apply to the $kpsewhich variable; see its
1523 documentation.)
1524
1525 Placeholders: Supposed you wanted latexmk to use the command elatex in
1526 place of the regular latex command, and suppose moreover that you
1527 wanted to give it the option "--shell-escape". You could do this by
1528 the following setting:
1529
1530 $latex = 'elatex --shell-escape %O %S';
1531
1532 The two items starting with the % character are placeholders. These
1533 are substituted by appropriate values before the command is run. Thus
1534 %S will be replaced by the source file that elatex will be applied to,
1535 and %O will be replaced by any options that latexmk has decided to use
1536 for this command. (E.g., if you used the -silent option in the invoca‐
1537 tion of latexmk, it results in the replacement of %O by "-interac‐
1538 tion=batchmode".)
1539
1540 The available placeholders are:
1541
1542 %A basename of the main tex file. Unlike %R, this is unaffected by
1543 the setting of a jobname by the -jobname option or the $jobname
1544 configuration value.
1545
1546 %B base of filename for current command. E.g., if a postscript
1547 file document.ps is being made from the dvi file document.dvi,
1548 then the basename is document.
1549
1550 %D destination file (e.g., the name of the postscript file when
1551 converting a dvi file to postscript).
1552
1553 %O options
1554
1555 %P If the variable $pre_tex_code is non-empty, then %P is substi‐
1556 tuted by the contents of $pre_tex_code followed by
1557 \input{SOURCE}, where SOURCE stands for the name of the source
1558 file. Appropriate quoting is done. This enables TeX code to be
1559 passed to one of the *latex engines to be executed before the
1560 source file is read.
1561
1562 If the variable $pre_tex_code is the empty string, then %P is
1563 equivalent to %S.
1564
1565 %R root filename. This is the base name for the main tex file.
1566
1567 By default this is the basename of the main tex file. However
1568 the value can be changed by the use of the -jobname option or
1569 the $jobname configuration variable.
1570
1571 %S source file (e.g., the name of the dvi file when converting a
1572 .dvi file to ps).
1573
1574 %T The name of the primary tex file.
1575
1576 %U If the variable $pre_tex_code is non-empty, then its value is
1577 substituted for %U (appropriately quoted). Otherwise it is
1578 replaced by a null string.
1579
1580 %Y Name of directory for auxiliary output files (see the configura‐
1581 tion variable $aux_dir). A directory separation character ('/')
1582 is appended if $aux_dir is non-empty and does not end in a suit‐
1583 able character, with suitable characters being those appropriate
1584 to UNIX and MS-Windows, i.e., ':', '/' and '\'. Note that if
1585 after initialization, $out_dir is set, but $aux_dir is not set
1586 (i.e., it is blank), then latexmk sets $aux_dir to the same
1587 value $out_dir.
1588
1589 %Z Name of directory for output files (see the configuration vari‐
1590 able $out_dir). A directory separation character ('/') is
1591 appended if $out_dir is non-empty and does not end in a suitable
1592 character, with suitable characters being those appropriate to
1593 UNIX and MS-Windows, i.e., ':', '/' and '\'.
1594
1595 If for some reason you need a literal % character in your string not
1596 subject to the above rules, use "%%".
1597
1598 Appropriate quoting will be applied to the filename substitutions, so
1599 you mustn't supply them yourself even if the names of your files have
1600 spaces in them. (But if your TeX filenames have spaces in them, beware
1601 that some older versions of the TeX program cannot correctly handle
1602 filenames containing spaces.) In case latexmk's quoting does not work
1603 correctly on your system, you can turn it off -- see the documentation
1604 for the variable $quote_filenames.
1605
1606 See the default values in the section "List of configuration variables
1607 usable in initialization files" for what is normally the most appropri‐
1608 ate usage.
1609
1610 If you omit to supply any placeholders whatever in the specification of
1611 a command, latexmk will supply what its author thinks are appropriate
1612 defaults. This gives compatibility with configuration files for previ‐
1613 ous versions of latexmk, which didn't use placeholders.
1614
1615 "Detaching" a command: Normally when latexmk runs a command, it waits
1616 for the command to run to completion. This is appropriate for commands
1617 like latex, of course. But for previewers, the command should normally
1618 run detached, so that latexmk gets the previewer running and then
1619 returns to its next task (or exits if there is nothing else to do). To
1620 achieve this effect of detaching a command, you need to precede the
1621 command name with "start ", as in
1622
1623 $dvi_previewer = 'start xdvi %O %S';
1624
1625 This will be translated to whatever is appropriate for your operating
1626 system.
1627
1628 Notes: (1) In some circumstances, latexmk will always run a command
1629 detached. This is the case for a previewer in preview continuous mode,
1630 since otherwise previewing continuously makes no sense. (2) This pre‐
1631 cludes the possibility of running a command named start. (3) If the
1632 word start occurs more than once at the beginning of the command
1633 string, that is equivalent to having just one. (4) Under cygwin, some
1634 complications happen, since cygwin amounts to a complicated merging of
1635 UNIX and MS-Windows. See the source code for how I've handled the
1636 problem.
1637
1638 Command names containing spaces: Under MS-Windows it is common that the
1639 name of a command includes spaces, since software is often installed in
1640 a subdirectory of "C:\Program Files". Such command names should be
1641 enclosed in double quotes, as in
1642
1643 $lpr_pdf = '"c:/Program Files/Ghostgum/gsview/gsview32.exe" /p
1644 %S';
1645 $pdf_previewer = 'start "c:/Program Files/SumatraPDF/Suma‐
1646 traPDF.exe" %O %S';
1647 $pdf_previewer = 'start "c:/Program Files/SumatraPDF (x86)/Suma‐
1648 traPDF.exe" %O %S';
1649
1650
1651 (Note about the above example: Under MS-Windows forward slashes are
1652 equivalent to backslashes in a filename under almost all circumstances,
1653 provided that the filename is inside double quotes. It is easier to
1654 use forward slashes in examples like the one above, since then one does
1655 not have to worry about the rules for dealing with forward slashes in
1656 strings in the Perl language.)
1657
1658 Command names under Cygwin: If latexmk is executed by Cygwin's Perl,
1659 be particularly certain that pathnames in commands have forward slashes
1660 not the usual backslashes for the separator of pathname components.
1661 See the above examples. Backslashes often get misinterpreted by the
1662 Unix shell used by Cygwin's Perl to execute external commands. Forward
1663 slashes don't suffer from this problem, and (when quoted, as above) are
1664 equally acceptable to MS-Windows.
1665
1666 Using MS-Windows file associations: A useful trick under modern ver‐
1667 sions of MS-Windows (e.g., WinXP) is to use just the command 'start' by
1668 itself:
1669
1670 $dvi_previewer = 'start %S';
1671
1672 Under MS-Windows, this will cause to be run whatever program the system
1673 has associated with dvi files. (The same applies for a postscript
1674 viewer and a pdf viewer.) But note that this trick is not always suit‐
1675 able for the pdf previwer, if your system has acroread for the default
1676 pdf viewer. As explained elsewhere, acroread under MS-Windows does not
1677 work well with latex and latexmk, because acroread locks the pdf file.
1678
1679 Not using a certain command: If a command is not to be run, the command
1680 name NONE is used, as in
1681
1682 $lpr = 'NONE lpr';
1683
1684 This typically is used when an appropriate command does not exist on
1685 your system. The string after the "NONE" is effectively a comment.
1686
1687 Options to commands: Setting the name of a command can be used not only
1688 for changing the name of the command called, but also to add options to
1689 command. Suppose you want latexmk to use latex with source specials
1690 enabled. Then you might use the following line in an initialization
1691 file:
1692
1693 $latex = 'latex --src-specials %O %S';
1694
1695 Running a subroutine instead of an external command: Use a specifica‐
1696 tion starting with "internal", as in
1697
1698 $latex = 'internal mylatex %O %S';
1699 sub mylatex {
1700 my @args = @_;
1701 # Possible preprocessing here
1702 return system 'latex', @args;
1703 }
1704
1705 For some of the more exotic possibilities that then become available,
1706 see the section "ADVANCED CONFIGURATION: Some extra resources and
1707 advanced tricks". Also see some of the examples in the directory exam‐
1708 ple_rcfiles in the latexmk distribution.
1709
1710 Advanced tricks: Normally one specifies a single command for the com‐
1711 mands invoked by latexmk. Naturally, if there is some complicated
1712 additional processing you need to do in your special situation, you can
1713 write a script (or batch file) to do the processing, and then configure
1714 latexmk to use your script in place of the standard program.
1715
1716 You can also use a Perl subroutine instead of a script -- see above.
1717 This is generally the most flexible and portable solution.
1718
1719 It is also possible to configure latexmk to run multiple commands. For
1720 example, if when running pdflatex to generate a pdf file from a tex
1721 file you need to run another program after pdflatex to perform some
1722 extra processing, you could do something like:
1723
1724 $pdflatex = 'pdflatex --shell-escape %O %S; pst2pdf_for_latexmk
1725 %B';
1726
1727 This definition assumes you are using a UNIX-like system (which
1728 includes Linux and OS-X), so that the two commands to be run are sepa‐
1729 rated by the semicolon in the middle of the string.
1730
1731 If you are using MS-Windows, you would replace the above line by
1732
1733 $pdflatex = 'cmd /c pdflatex --shell-escape %O %S'
1734 . '&& pst2pdf_for_latexmk %B';
1735
1736 Here, the UNIX command separator ; is replaced by &&. In addition,
1737 there is a problem that some versions of Perl on MS-Windows do not obey
1738 the command separator; this problem is overcome by explicitly invoking
1739 the MS-Windows command-line processor cmd.exe.
1740
1741
1743 In this section are specified the variables whose values can be
1744 adjusted to configure latexmk. (See the earlier section "Configura‐
1745 tion/Initialization (rc) Files" for the files where the configurations
1746 are done.)
1747
1748 Default values are indicated in brackets. Note that for variables that
1749 are boolean in character, concerning whether latexmk does or does not
1750 behave in a certain way, a non-zero value, normally 1, indicates true,
1751 i.e., the behavior occurs, while a zero value indicates a false value,
1752 i.e., the behavior does not occur.
1753
1754
1755 $allow_switch [1]
1756
1757 This controls what happens when the output extension of latex,
1758 pdflatex, lualatex or xelatex differs from what is expected.
1759 (The possible extensions are .dvi, .pdf, .xdv.) This can happen
1760 with the use of the \pdfoutput macro in a document compiled
1761 under latex or pdflatex, or with the use of the \outputmode
1762 macro under lualatex. It can also happen with certain kinds of
1763 incorrect configuration.
1764
1765 In such a case, latexmk can appropriately adjust its network of
1766 rules. The adjustment is made if $allow_switch is on, and if no
1767 request for a dvi or ps file has been made.
1768
1769 See the section ALLOWING FOR CHANGE OF OUTPUT EXTENSION.
1770
1771
1772 $always_view_file_via_temporary [0]
1773 Whether .ps and .pdf files are initially to be made in a tempo‐
1774 rary directory and then moved to the final location. (This
1775 applies to dvips, dvipdf, and ps2pdf operations, and the filter‐
1776 ing operators on .dvi and .ps files. It does not apply to
1777 pdflatex, unfortunately, since pdflatex provides no way of spec‐
1778 ifying a chosen name for the output file.)
1779
1780 This use of a temporary file solves a problem that the making of
1781 these files can occupy a substantial time. If a viewer (notably
1782 gv) sees that the file has changed, it may read the new file
1783 before the program writing the file has not yet finished its
1784 work, which can cause havoc.
1785
1786 See the $pvc_view_file_via_temporary variable for a setting that
1787 applies only if preview-continuous mode (-pvc option) is used.
1788 See $tmpdir for the setting of the directory where the temporary
1789 file is created.
1790
1791
1792 $analyze_input_log_always [1]
1793
1794 After a run of latex (etc), always analyze .log for input files
1795 in the <...> and (...) constructions. Otherwise, only do the
1796 analysis when fls file doesn't exist or is out of date.
1797
1798 Under normal circumstances, the data in the fls file is reli‐
1799 able, and the test of the log file gets lots of false positives;
1800 usually $analyze_input_log_always is best set to zero. But the
1801 test of the log file is needed at least in the following situa‐
1802 tion: When a user needs to persuade latexmk that a certain file
1803 is a source file, and latexmk doesn't otherwise find it. Then
1804 the user can write code that causes a line with (...) to be
1805 written to log file. One important case is for lualatex, which
1806 doesn't always generate lines in the .fls file for input lua
1807 files. (The situation with lualatex is HIGHLY version depen‐
1808 dent, e.g., there was a big change between TeXLive 2016 and
1809 TeXLive 2017.)
1810
1811 To keep backward compatibility with older versions of latexmk,
1812 the default is to set $analyze_input_log_always to 1.
1813
1814
1815 $auto_rc_use [1]
1816 Whether to automatically read the standard initialization (rc)
1817 files, which are the system RC file, the user's RC file, and the
1818 RC file in the current directory. The command line option -norc
1819 can be used to turn this setting off. Each RC file could also
1820 turn this setting off, i.e., it could set $auto_rc_use to zero
1821 to prevent automatic reading of the later RC files.
1822
1823 This variable does not affect the reading of RC files specified
1824 on the command line by the -r option.
1825
1826 $aux_dir [""]
1827 The directory in which auxiliary files (aux, log, etc) are to be
1828 written by a run of *latex. If this variable is not set, but
1829 $out_dir is set, then $aux_dir is set to $out_dir, which is the
1830 directory to which general output files are to be written.
1831
1832 Important note: The effect of $aux_dir, if different from
1833 $out_dir, is achieved by giving *latex the -aux-directory. Cur‐
1834 rently (Dec. 2011 and later) this only works on the MiKTeX ver‐
1835 sion of *latex.
1836
1837 See also the documentation of $out_dir for some complications on
1838 what directory names are suitable.
1839
1840 If you also use the -cd option, and $out_dir (or $aux_dir) con‐
1841 tains a relative path, then the path is interpreted relative to
1842 the document directory.
1843
1844 $banner [0]
1845 If nonzero, the banner message is printed across each page when
1846 converting the dvi file to postscript. Without modifying the
1847 variable $banner_message, this is equivalent to specifying the
1848 -d option.
1849
1850 Note that if $banner is nonzero, the $postscript_mode is assumed
1851 and the postscript file is always generated, even if it is newer
1852 than the dvi file.
1853
1854 $banner_intensity [0.95]
1855 Equivalent to the -bi option, this is a decimal number between 0
1856 and 1 that specifies how dark to print the banner message. 0 is
1857 black, 1 is white. The default is just right if your toner car‐
1858 tridge isn't running too low.
1859
1860 $banner_message ["DRAFT"]
1861 The banner message to print across each page when converting the
1862 dvi file to postscript. This is equivalent to the -bm option.
1863
1864 $banner_scale [220.0]
1865 A decimal number that specifies how large the banner message
1866 will be printed. Experimentation is necessary to get the right
1867 scale for your message, as a rule of thumb the scale should be
1868 about equal to 1100 divided by the number of characters in the
1869 message. The Default is just right for 5 character messages.
1870 This is equivalent to the -bs option.
1871
1872 @BIBINPUTS
1873 This is an array variable, now mostly obsolete, that specifies
1874 directories where latexmk should look for .bib files. By
1875 default it is set from the BIBINPUTS environment variable of the
1876 operating system. If that environment variable is not set, a
1877 single element list consisting of the current directory is set.
1878 The format of the directory names depends on your operating sys‐
1879 tem, of course. Examples for setting this variable are:
1880
1881 @BIBINPUTS = ( ".", "C:\\bibfiles" );
1882 @BIBINPUTS = ( ".", "\\server\bibfiles" );
1883 @BIBINPUTS = ( ".", "C:/bibfiles" );
1884 @BIBINPUTS = ( ".", "//server/bibfiles" );
1885 @BIBINPUTS = ( ".", "/usr/local/texmf/bibtex/bib" );
1886
1887 Note that under MS Windows, either a forward slash "/" or a
1888 backward slash "\" can be used to separate pathname components,
1889 so the first two and the second two examples are equivalent.
1890 Each backward slash should be doubled to avoid running afoul of
1891 Perl's rules for writing strings.
1892
1893 Important note: This variable is now mostly obsolete in the cur‐
1894 rent version of latexmk, since it has a better method of search‐
1895 ing for files using the kpsewhich command. However, if your
1896 system is an unusual one without the kpsewhich command, you may
1897 need to set the variable @BIBINPUTS.
1898
1899 $biber ["biber %O %S"]
1900 The biber processing program.
1901
1902 $biber_silent_switch ["--onlylog"]
1903 Switch(es) for the biber processing program when silent mode is
1904 on.
1905
1906 $bibtex ["bibtex %O %S"]
1907 The BibTeX processing program.
1908
1909 $bibtex_fudge [0]
1910 When using bibtex, whether to take special action to allow older
1911 versions of bibtex to work when $out_dir or $aux_dir is speci‐
1912 fied. With bibtex from about 2019, this special action is
1913 longer be required; hence the default is not to do it.
1914
1915 $bibtex_silent_switch ["-terse"]
1916 Switch(es) for the BibTeX processing program when silent mode is
1917 on.
1918
1919 $bibtex_use [1]
1920 Under what conditions to run bibtex or biber. When latexmk dis‐
1921 covers from the log file that one (or more) bibtex/biber-gener‐
1922 ated bibliographies are used, it can run bibtex or biber when‐
1923 ever it appears necessary to regenerate the bbl file(s) from
1924 their source bib database file(s). But sometimes, the bib
1925 file(s) are not available (e.g., for a document obtained from an
1926 external archive), but the bbl files are provided. In that case
1927 use of bibtex or biber will result in incorrect overwriting of
1928 the precious bbl files. The variable $bibtex_use controls
1929 whether this happens, and also controls whether or not .bbl
1930 files are deleted in a cleanup operation.
1931
1932 The possible values of $bibtex_use are:
1933 0: never use BibTeX or biber; never delete .bbl files in a
1934 cleanup.
1935 1: only use bibtex or biber if the bib files exist; never
1936 delete .bbl files in a cleanup.
1937 1.5: only use bibtex or biber if the bib files exist; condi‐
1938 tionally delete .bbl files in a cleanup (i.e., delete them only
1939 when the bib files all exist).
1940 2: run bibtex or biber whenever it appears necessary to update
1941 the bbl files, without testing for the existence of the bib
1942 files; always delete .bbl files in a cleanup.
1943
1944 Note that the value 1.5 does not work properly if the document
1945 uses biber instead of bibtex. (There's a long story why not.)
1946
1947
1948 $cleanup_includes_cusdep_generated [0]
1949 If nonzero, specifies that cleanup also deletes files that are
1950 generated by custom dependencies. (When doing a clean up, e.g.,
1951 by use of the -C option, custom dependencies are those listed in
1952 the .fdb_latexmk file from a previous run.)
1953
1954 $cleanup_includes_generated [0]
1955 If nonzero, specifies that cleanup also deletes files that are
1956 detected in the fls file (or failing that, in log file) as being
1957 generated. It will also include files made from these first
1958 generation generated files.
1959
1960 This operation is somewhat dangerous, and can have unintended
1961 consequences, since the files to be deleted are determined from
1962 a file created by *latex, which can contain erroneous informa‐
1963 tion. Therefore this variable is turned off by default, and then
1964 files to be deleted are restricted to those explictly specified
1965 by patterns configured in the variables clean_ext,
1966 clean_full_ext, and @generated_exts, together with those very
1967 standard cases that are hardwired into latexmk (e.g., .log
1968 files).
1969
1970 $cleanup_mode [0]
1971 If nonzero, specifies cleanup mode: 1 for full cleanup, 2 for
1972 cleanup except for .dvi, .ps and .pdf files, 3 for cleanup
1973 except for dep and aux files. (There is also extra cleaning as
1974 specified by the $clean_ext, $clean_full_ext and @generated_exts
1975 variables.)
1976
1977 This variable is equivalent to specifying one of the -c or -C
1978 options. But there should be no need to set this variable from
1979 an RC file.
1980
1981 $clean_ext [""]
1982 Extra extensions of files for latexmk to remove when any of the
1983 clean-up options (-c or -C) is selected. The value of this
1984 variable is a string containing the extensions separated by spa‐
1985 ces.
1986
1987 It is also possible to specify a more general pattern of file to
1988 be deleted, by using the place holder %R, as in commands, and it
1989 is also possible to use wildcards. Thus setting
1990
1991 $clean_ext = "out %R-blx.bib %R-figures*.log pythontex-
1992 files-%R/*";
1993
1994 in an initialization file will imply that when a clean-up opera‐
1995 tion is specified, not only is the standard set of files
1996 deleted, but also files of the form FOO.out, FOO-blx.bib, %R-
1997 figures*.log, and pythontex-files-FOO/*, where FOO stands for
1998 the basename of the file being processed (as in FOO.tex).
1999
2000 The files to be deleted are relative to the directory specified
2001 by $aux_dir. (Note that if $out_dir but not $aux_dir is set,
2002 then in its initialization, latexmk sets $aux_dir equal to
2003 $out_dir. A normal situation is therefore that $aux_dir equals
2004 $out_dir, which is the only case supported by TeXLive, unlike
2005 MiKTeX.)
2006
2007 The filenames specfied for a clean-up operation can refer not
2008 only to regular files but also to directories. Directories are
2009 only deleted if they are empty. An example of an application is
2010 to pythontex, which creates files in a particular directory.
2011 You can arrange to remove both the files and the directory by
2012 setting
2013
2014 $clean_ext = "pythontex-files-%R pythontex-files-%R";
2015
2016 See also the variable @generated_exts.
2017
2018 $clean_full_ext [""]
2019 Extra extensions of files for latexmk to remove when the -C
2020 option is selected, i.e., extensions of files to remove when the
2021 .dvi, etc files are to be cleaned-up.
2022
2023 More general patterns are allowed, as for $clean_ext.
2024
2025 The files specified by $clean_full_ext to be deleted are rela‐
2026 tive to the directory specified by $out_dir.
2027
2028
2029 $compiling_cmd [""], $failure_cmd [""], $warning_cmd [""], $success_cmd
2030 [""]
2031
2032 These variables specify commands that are executed at certain
2033 points of compilations. One motivation for their existance is
2034 to allow very useful convenient visual indications of compila‐
2035 tion status even when the window receiving the screen output of
2036 the compilation is hidden. This is particularly useful in pre‐
2037 view-continuous mode.
2038
2039 The commands are executed at the following points: $compil‐
2040 ing_cmd at the start of compilation, $success_cmd at the end of
2041 a completely successful compilation, $failure_cmd at the end of
2042 an unsuccessful compilation, $warning_cmd at the of an otherwise
2043 successful compilation that gives warnings about undefined cita‐
2044 tions or references or about multiply defined references. If any
2045 of above variables is undefined or blank (the default situa‐
2046 tion), then the corresponding command is not executed.
2047
2048 However, when $warning_cmd is not set, then in the case of a
2049 compilation with warnings about references or citations, but
2050 with no other error, one or other of $success_cmd or $fail‐
2051 ure_cmd is used (if it is set) according to the setting of
2052 $warnings_as_errors.
2053
2054 An example of a simple setting of these variables is as follows
2055
2056 $compiling_cmd = "xdotool search --name \"%D\" set_window
2057 --name \"%D compiling\"";
2058 $success_cmd = "xdotool search --name \"%D\" set_window
2059 --name \"%D OK\"";
2060 $warning_cmd = "xdotool search --name \"%D\" ".
2061 "set_window --name \"%D CITE/REF ISSUE\"";
2062 $failure_cmd = "xdotool search --name \"%D\" set_window
2063 --name \"%D FAILURE\"";
2064
2065 These assume that the program xdotool is installed, that the
2066 previewer is using an X-Window system for display, and that the
2067 title of the window contains the name of the displayed file, as
2068 it normally does. When the commands are executed, the place‐
2069 holder string %D is replaced by the name of the destination
2070 file, which is the previewed file. The above commands result in
2071 an appropriate string being appended to the filename in the win‐
2072 dow title: " compiling", " OK", or " FAILURE".
2073
2074 Other placeholders that can be used are %S, %T, and %R, with %S
2075 and %T normally being identical. These can be useful for a com‐
2076 mand changing the title of the edit window. The visual indica‐
2077 tion in a window title can useful, since the user does not have
2078 to keep shifting attention to the (possibly hidden) compilation
2079 window to know the status of the compilation.
2080
2081 More complicated situations can best be handled by defining a
2082 Perl subroutine to invoke the necessary commands, and using the
2083 "internal" keyword in the definitions to get the subroutine to
2084 be invoked. (See the section "Format of Command Specifications"
2085 for how to do this.)
2086
2087 Naturally, the above settings that invoke the xdotool program
2088 are only applicable when the X-Window system is used for the
2089 relevant window(s). For other cases, you will have to find what
2090 software solutions are available.
2091
2092
2093 @cus_dep_list [()]
2094 Custom dependency list -- see section on "Custom Dependencies".
2095
2096 @default_excluded_files [()]
2097 When latexmk is invoked with no files specified on the command
2098 line, then, by default, it will process all files in the current
2099 directory with the extension .tex. (In general, it will process
2100 the files specified in the @default_files variable.)
2101
2102 But sometimes you want to exclude particular files from this
2103 default list. In that case you can specify the excluded files
2104 in the array @default_excluded_files. For example if you wanted
2105 to process all .tex files with the exception of common.tex,
2106 which is a not a standard alone LaTeX file but a file input by
2107 some or all of the others, you could do
2108
2109 @default_files = ("*.tex");
2110
2111 @default_excluded_files = ("common.tex");
2112
2113 If you have a variable or large number of files to be processed,
2114 this method saves you from having to list them in detail in
2115 @default_files and having to update the list every time you
2116 change the set of files to be processed.
2117
2118 Notes: 1. This variable has no effect except when no files are
2119 specified on the latexmk command line. 2. Wildcards are allowed
2120 in @default_excluded_files.
2121
2122 @default_files [("*.tex")]
2123 Default list of files to be processed.
2124
2125 If no filenames are specified on the command line, latexmk pro‐
2126 cesses all tex files specified in the @default_files variable,
2127 which by default is set to all tex files ("*.tex") in the cur‐
2128 rent directory. This is a convenience: just run latexmk and it
2129 will process an appropriate set of files. But sometimes you
2130 want only some of these files to be processed. In this case you
2131 can list the files to be processed by setting @default_files in
2132 an initialization file (e.g., the file "latexmkrc" in the cur‐
2133 rent directory). Then if no files are specified on the command
2134 line then the files you specify by setting @default_files are
2135 processed.
2136
2137 Three examples:
2138
2139 @default_files = ("paper_current");
2140
2141 @default_files = ("paper1", "paper2.tex");
2142
2143 @default_files = ("*.tex", "*.dtx");
2144
2145 Note that more than file may be given, and that the default
2146 extension is ".tex". Wild cards are allowed. The parentheses
2147 are because @default_files is an array variable, i.e., a
2148 sequence of filename specifications is possible.
2149
2150 If you want latexmk to process all .tex files with a few excep‐
2151 tions, see the @default_excluded_files array variable.
2152
2153 $dependents_phony [0]
2154 If a list of dependencies is output, this variable determines
2155 whether to include a phony target for each source file. If you
2156 use the dependents list in a Makefile, the dummy rules work
2157 around errors make gives if you remove header files without
2158 updating the Makefile to match.
2159
2160 $dependents_list [0]
2161 Whether to display a list(s) of dependencies at the end of a
2162 run.
2163
2164 $deps_file ["-"]
2165 Name of file to receive list(s) of dependencies at the end of a
2166 run, to be used if $dependesnt_list is set. If the filename is
2167 "-", then the dependency list is set to stdout (i.e., normally
2168 the screen).
2169
2170 $do_cd [0]
2171 Whether to change working directory to the directory specified
2172 for the main source file before processing it. The default
2173 behavior is not to do this, which is the same as the behavior of
2174 *latex programs. This variable is set by the -cd and -cd-
2175 options on latexmk's command line.
2176
2177 $dvi_filter [empty]
2178 The dvi file filter to be run on the newly produced dvi file
2179 before other processing. Equivalent to specifying the -dF
2180 option.
2181
2182 $dvi_mode [See below for default]
2183 If nonzero, generate a dvi version of the document. Equivalent
2184 to the -dvi option.
2185
2186 The variable $dvi_mode defaults to 0, but if no explicit
2187 requests are made for other types of file (postscript, pdf),
2188 then $dvi_mode will be set to 1. In addition, if a request for
2189 a file for which a .dvi file is a prerequisite, then $dvi_mode
2190 will be set to 1.
2191
2192 $dvi_previewer ["start xdvi %O %S" under UNIX]
2193 The command to invoke a dvi-previewer. [Under MS-Windows the
2194 default is "start"; then latexmk arranges to use the MS-Windows
2195 start program, which will cause to be run whatever command the
2196 system has associated with .dvi files.]
2197
2198 Important note: Normally you will want to have a previewer run
2199 detached, so that latexmk doesn't wait for the previewer to ter‐
2200 minate before continuing its work. So normally you should pre‐
2201 fix the command by "start ", which flags to latexmk that it
2202 should do the detaching of the previewer itself (by whatever
2203 method is appropriate to the operating system). But sometimes
2204 letting latexmk do the detaching is not appropriate (for a vari‐
2205 ety of non-trivial reasons), so you should put the "start " bit
2206 in yourself, whenever it is needed.
2207
2208 $dvi_previewer_landscape ["start xdvi %O %S"]
2209 The command to invoke a dvi-previewer in landscape mode. [Under
2210 MS-Windows the default is "start"; then latexmk arranges to use
2211 the MS-Windows start program, which will cause to be run what‐
2212 ever command the system has associated with .dvi files.]
2213
2214 $dvipdf ["dvipdf %O %S %D"]
2215 Command to convert .dvi to .pdf file. A common reconfiguration
2216 is to use the dvipdfm command, which needs its arguments in a
2217 different order:
2218
2219 $dvipdf = "dvipdfm %O -o %D %S";
2220
2221 WARNING: The default dvipdf script generates pdf files with
2222 bitmapped fonts, which do not look good when viewed by acroread.
2223 That script should be modified to give dvips the options "-P
2224 pdf" to ensure that type 1 fonts are used in the pdf file.
2225
2226 $dvipdf_silent_switch ["-q"]
2227 Switch(es) for dvipdf program when silent mode is on.
2228
2229 N.B. The standard dvipdf program runs silently, so adding the
2230 silent switch has no effect, but is actually innocuous. But if
2231 an alternative program is used, e.g., dvipdfmx, then the silent
2232 switch has an effect. The default setting is correct for
2233 dvipdfm and dvipdfmx.
2234
2235 $dvips ["dvips %O -o %D %S"]
2236 The program to used as a filter to convert a .dvi file to a .ps
2237 file. If pdf is going to be generated from pdf, then the value
2238 of the $dvips_pdf_switch variable -- see below -- will be
2239 included in the options substituted for "%O".
2240
2241 $dvips_landscape ["dvips -tlandscape %O -o %D %S"]
2242 The program to used as a filter to convert a .dvi file to a .ps
2243 file in landscape mode.
2244
2245 $dvips_pdf_switch ["-P pdf"]
2246 Switch(es) for dvips program when pdf file is to be generated
2247 from .ps file.
2248
2249 $dvips_silent_switch ["-q"]
2250 Switch(es) for dvips program when silent mode is on.
2251
2252 $dvi_update_command [""]
2253 When the dvi previewer is set to be updated by running a com‐
2254 mand, this is the command that is run. See the information for
2255 the variable $dvi_update_method for further information, and see
2256 information on the variable $pdf_update_method for an example
2257 for the analogous case of a pdf previewer.
2258
2259 $dvi_update_method [2 under UNIX, 1 under MS-Windows]
2260 How the dvi viewer updates its display when the dvi file has
2261 changed. The values here apply equally to the
2262 $pdf_update_method and to the $ps_update_method variables.
2263 0 => update is automatic,
2264 1=> manual update by user, which may only mean a mouse click
2265 on the viewer's window or may mean a more serious action.
2266 2 => Send the signal, whose number is in the variable
2267 $dvi_update_signal. The default value under UNIX is suitable
2268 for xdvi.
2269 3 => Viewer cannot do an update, because it locks the file.
2270 (As with acroread under MS-Windows.)
2271 4 => run a command to do the update. The command is speci‐
2272 fied by the variable $dvi_update_command.
2273
2274 See information on the variable $pdf_update_method for an exam‐
2275 ple of updating by command.
2276
2277 $dvi_update_signal [Under UNIX: SIGUSR1, which is a system-dependent
2278 value]
2279 The number of the signal that is sent to the dvi viewer when it
2280 is updated by sending a signal -- see the information on the
2281 variable $dvi_update_method. The default value is the one
2282 appropriate for xdvi on a UNIX system.
2283
2284 $failure_cmd [undefined]
2285 See the documentation for $compiling_cmd.
2286
2287 $fdb_ext ["fdb_latexmk"]
2288 The extension of the file which latexmk generates to contain a
2289 database of information on source files. You will not normally
2290 need to change this.
2291
2292 $filetime_causality_threshold [5]; $filetime_offset_report_threshold
2293 [30]. (Units of seconds.)
2294
2295 These variables control how latexmk deals with the following
2296 issue, which can affect the use of files that are on a remote
2297 filesystem (network share) instead of being on a file system
2298 local to the computer running latexmk. Almost users will not
2299 have to worry about these settings, and can ignore the following
2300 explanation.
2301
2302 In almost all situations, latexmk does not need to use the time
2303 stamps of the files it works with. However, there are a couple
2304 of situations when it needs to know whether a certain file was
2305 created in the current run of a program (e.g., *latex) or is a
2306 leftover file from a previous run. It does this by comparing the
2307 modification time of the file with the system time just before
2308 the program was started. If the modification time is earlier
2309 than when the program was started, the file is a leftover file,
2310 which latexmk treats as if it were not created. If the filetime
2311 is at least the program start time, then it can be assumed that
2312 the file was created in the current run.
2313
2314 Unfortunately, this test can fail if the file is on a remote
2315 system, since its system time is not necessarily synchronized
2316 with that of the local system; the timestamps on the remote
2317 files are set by the remote system, not the local system. Gen‐
2318 erally, modern operating systems regularly synchronize their
2319 time with a server, so the non-synchronization is mostly small
2320 (a second or so, or a few seconds). But even a small difference
2321 can mess up latexmk's test.
2322
2323 Latexmk measures the time difference between the time on the two
2324 systems and compensates for this. But the measurement (in a
2325 system-independent way) is only accurate to a second or two. So
2326 latexmk allows for a threshold on the difference between file
2327 and system time before it concludes that a file is a leftover
2328 file from a previous run. The configuration variable $file‐
2329 time_causality_theshhold, which in units of seconds, specifies
2330 this threshold. Luckily high precision is not needed. The pre‐
2331 vious run is normally the previous run in a human run-edit-run
2332 cycle, and is at least many seconds back. A few seconds is
2333 therefore appropriate for the threshold, $filetime_causal‐
2334 ity_theshhold; it should be non-negative always, and should be
2335 bigger than 2 if a remote filesystem or network share is used.
2336
2337 If the difference in system times on the two systems is large,
2338 it normally indicates that at least one of the systems is mis‐
2339 configured. The variable $filetime_offset_report_threshold
2340 specifies the smallest size of the difference (or offset) in
2341 seconds between the times of the local and remote system beyond
2342 which the offset is reported. This is reported at the point in
2343 the latexmk's progress that it measures the offset. The report
2344 is made if silent mode is used and diagnostic mode is not on.
2345
2346
2347 $force_mode [0]
2348 If nonzero, continue processing past minor latex errors includ‐
2349 ing unrecognized cross references. Equivalent to specifying the
2350 -f option.
2351
2352 @generated_exts [( aux , bbl , idx , ind , lof , lot , out , toc ,
2353 $fdb_ext )]
2354 This contains a list of extensions for files that are generated
2355 during a LaTeX run and that are read in by LaTeX in later runs,
2356 either directly or indirectly.
2357
2358 This list specifies files known to be generated by *latex. It
2359 is used in two ways: (a) The specified files are deleted in a
2360 cleanup operation (with the -c, -C, -CA, -g and -gg options),
2361 and (b) It affects the determination of whether a rerun of
2362 *latex is needed after a run that gives an error.
2363
2364 (Concerning item (b): Normally, a change of a source file during
2365 a run should provoke a rerun. This includes a file generated by
2366 LaTeX, e.g., an aux file, that is read in on subsequent runs.
2367 But after a run that results in an error, a new run should not
2368 occur until the user has made a change in the files. But the
2369 user may have corrected an error in a source .tex file during
2370 the run. So latexmk needs to distinguish user-generated and
2371 automatically generated files; it determines the automatically
2372 generated files as those with extensions in the list in @gener‐
2373 ated_exts.)
2374
2375 A convenient way to add an extra extension to the list, without
2376 losing the already defined ones is to use a push command in the
2377 line in an RC file. E.g.,
2378
2379 push @generated_exts, "end";
2380
2381 adds the extension "end" to the list of predefined generated
2382 extensions. (This extension is used by the RevTeX package, for
2383 example.)
2384
2385 $go_mode [0]
2386 If nonzero, process files regardless of timestamps, and is then
2387 equivalent to the -g option.
2388
2389 %hash_calc_ignore_pattern
2390 !!!This variable is for experts only!!!
2391
2392 The general rule latexmk uses for determining when an extra run
2393 of some program is needed is that one of the source files has
2394 changed. But consider for example a latex package that causes
2395 an encapsulated postscript file (an "eps" file) to be made that
2396 is to be read in on the next run. The file contains a comment
2397 line giving its creation date and time. On the next run the
2398 time changes, latex sees that the eps file has changed, and
2399 therefore reruns latex. This causes an infinite loop, that is
2400 only terminated because latexmk has a limit on the number of
2401 runs to guard against pathological situations.
2402
2403 But the changing line has no real effect, since it is a comment.
2404 You can instruct latex to ignore the offending line as follows:
2405
2406 $hash_calc_ignore_pattern{'eps'} = '^%%CreationDate: ';
2407
2408 This creates a rule for files with extension .eps about lines to
2409 ignore. The left-hand side is a Perl idiom for setting an item
2410 in a hash. Note that the file extension is specified without a
2411 period. The value, on the right-hand side, is a string contain‐
2412 ing a regular expresssion. (See documentation on Perl for how
2413 they are to be specified in general.) This particular regular
2414 expression specifies that lines beginning with "%%CreationDate:
2415 " are to be ignored in deciding whether a file of the given
2416 extension .eps has changed.
2417
2418 There is only one regular expression available for each exten‐
2419 sion. If you need more one pattern to specify lines to ignore,
2420 then you need to combine the patterns into a single regular
2421 expression. The simplest method is separate the different sim‐
2422 ple patterns by a vertical bar character (indicating "alterna‐
2423 tion" in the jargon of regular expressions). For example,
2424
2425 $hash_calc_ignore_pattern{'eps'} = '^%%CreationDate:
2426 |^%%Title: ';
2427
2428 causes lines starting with either "^%%CreationDate: " or
2429 "^%%Title: " to be ignored.
2430
2431 It may happen that a pattern to be ignored is specified in, for
2432 example, in a system or user initialization file, and you wish
2433 to remove this in a file that is read later. To do this, you
2434 use Perl's delete function, e.g.,
2435
2436 delete $hash_calc_ignore_pattern{'eps'};
2437
2438
2439 $jobname [""]
2440
2441 This specifies the jobname, i.e., the basename that is used for
2442 generated files (.aux, .log, .dvi, .ps, .pdf, etc). If this
2443 variable is a null string, then the basename is the basename of
2444 the main tex file. (At present, the string in $jobname should
2445 not contain spaces.)
2446
2447 The placeholder '%A' is permitted. This will be substituted by
2448 the basename of the TeX file. The primary purpose is when a
2449 variety of tex files are to be processed, and you want to use a
2450 different jobname for each but one that is distinct for each.
2451 Thus if you wanted to compare compilations of a set of files on
2452 different operating systems, with distinct filenames for all the
2453 cases, you could set
2454
2455 $jobname = "%A-$^O";
2456
2457 in an initialization file. (Here $^O is a variable provided by
2458 perl that contains perl's name for the operating system.)
2459
2460 Suppose you had .tex files test1.tex and test2.tex. Then when
2461 you run
2462
2463 latexmk -pdf *.tex
2464
2465 both files will be compiled. The .aux, .log, and .pdf files
2466 will have basenames test1-MSWin32 ante test2-MSWin32 on a MS-
2467 Windows system, test1-darwin and test2-darwin on an OS-X system,
2468 and a variety of similar cases on linux systems.
2469
2470
2471 $kpsewhich ["kpsewhich %S"]
2472 The program called to locate a source file when the name alone
2473 is not sufficient. Most filenames used by latexmk have suffi‐
2474 cient path information to be found directly. But sometimes,
2475 notably when a .bib or a .bst file is found from the log file of
2476 a bibtex or biber run, only the base name of the file is known,
2477 but not its path. The program specified by $kpsewhich is used to
2478 find it.
2479
2480 (For advanced users: Because of the different way in which
2481 latexmk uses the command specified in $kpsewhich, some of the
2482 possibilities listed in the FORMAT OF COMMAND SPECIFICATIONS do
2483 not apply. The internal and start keywords are not available. A
2484 simple command specification with possible options and then "%S"
2485 is all that is guaranteed to work. Note that for other com‐
2486 mands, "%S" is substituted by a single source file. In contrast,
2487 for $kpsewhich, "%S" may be substituted by a long list of space-
2488 separated filenames, each of which is quoted. The result on
2489 STDOUT of running the command is then piped to latexmk.)
2490
2491 See also the @BIBINPUTS variable for another way that latexmk
2492 also uses to try to locate files; it applies only in the case of
2493 .bib files.
2494
2495 $kpsewhich_show [0]
2496 Whether to show diagnostics about invocations of kpsewhich: the
2497 command line use to invoke it and the results. These diagnos‐
2498 tics are shown if $kpsewhich_show is non-zero or if diagnostics
2499 mode is on. (But in the second case, lots of other diagnostics
2500 are also shown.) Without these diagnostics there is nothing
2501 visible in latexmk's screen output about invocations of kpse‐
2502 which.
2503
2504 $landscape_mode [0]
2505 If nonzero, run in landscape mode, using the landscape mode pre‐
2506 viewers and dvi to postscript converters. Equivalent to the -l
2507 option. Normally not needed with current previewers.
2508
2509 $latex ["latex %O %S"]
2510 Specifies the command line for the LaTeX processing program.
2511 Note that as with other programs, you can use this variable not
2512 just to change the name of the program used, but also specify
2513 options to the program. E.g.,
2514
2515 $latex = "latex --src-specials %O %S";
2516
2517 To do a coordinated setting of all of $latex, $pdflatex, $luala‐
2518 tex, and $xelatex, see the section "Advanced Configuration".
2519
2520
2521 %latex_input_extensions
2522 This variable specifies the extensions tried by latexmk when it
2523 finds that a LaTeX run resulted in an error that a file has not
2524 been found, and the file is given without an extension. This
2525 typically happens when LaTeX commands of the form \input{file}
2526 or \includegraphics{figure}, when the relevant source file does
2527 not exist.
2528
2529 In this situation, latexmk searches for custom dependencies to
2530 make the missing file(s), but restricts it to the extensions
2531 specified by the variable %latex_input_extensions. The default
2532 extensions are 'tex' and 'eps'.
2533
2534 (For Perl experts: %latex_input_extensions is a hash whose keys
2535 are the extensions. The values are irrelevant.) Two subrou‐
2536 tines are provided for manipulating this and the related vari‐
2537 able %pdflatex_input_extensions, add_input_ext and
2538 remove_input_ext. They are used as in the following examples
2539 are possible lines in an initialization file:
2540
2541 remove_input_ext( 'latex', 'tex' );
2542
2543 removes the extension 'tex' from latex_input_extensions
2544
2545 add_input_ext( 'latex', 'asdf' );
2546
2547 add the extension 'asdf to latex_input_extensions. (Naturally
2548 with such an extension, you should have made an appropriate cus‐
2549 tom dependency for latexmk, and should also have done the appro‐
2550 priate programming in the LaTeX source file to enable the file
2551 to be read. The standard extensions are handled by LaTeX and
2552 its graphics/graphicx packages.)
2553
2554 $latex_silent_switch ["-interaction=batchmode"]
2555 Switch(es) for the LaTeX processing program when silent mode is
2556 on.
2557
2558 If you use MikTeX, you may prefer the results if you configure
2559 the options to include -c-style-errors, e.g., by the following
2560 line in an initialization file
2561
2562 $latex_silent_switch = "-interaction=batchmode -c-style-
2563 errors";
2564
2565
2566 $lpr ["lpr %O %S" under UNIX/Linux, "NONE lpr" under MS-Windows]
2567 The command to print postscript files.
2568
2569 Under MS-Windows (unlike UNIX/Linux), there is no standard pro‐
2570 gram for printing files. But there are ways you can do it. For
2571 example, if you have gsview installed, you could use it with the
2572 option "/p":
2573
2574 $lpr = '"c:/Program Files/Ghostgum/gsview/gsview32.exe" /p';
2575
2576 If gsview is installed in a different directory, you will need
2577 to make the appropriate change. Note the combination of single
2578 and double quotes around the name. The single quotes specify
2579 that this is a string to be assigned to the configuration vari‐
2580 able $lpr. The double quotes are part of the string passed to
2581 the operating system to get the command obeyed; this is neces‐
2582 sary because one part of the command name ("Program Files") con‐
2583 tains a space which would otherwise be misinterpreted.
2584
2585 $lpr_dvi ["NONE lpr_dvi"]
2586 The printing program to print dvi files.
2587
2588 $lpr_pdf ["NONE lpr_pdf"]
2589 The printing program to print pdf files.
2590
2591 Under MS-Windows you could set this to use gsview, if it is
2592 installed, e.g.,
2593
2594 $lpr = '"c:/Program Files/Ghostgum/gsview/gsview32.exe" /p';
2595
2596 If gsview is installed in a different directory, you will need
2597 to make the appropriate change. Note the double quotes around
2598 the name: this is necessary because one part of the command name
2599 ("Program Files") contains a space which would otherwise be mis‐
2600 interpreted.
2601
2602 $lualatex ["lualatex %O %S"]
2603 Specifies the command line for the LaTeX processing program that
2604 is to be used when the lualatex program is called for (e.g., by
2605 the option -lualatex.
2606
2607 To do a coordinated setting of all of $latex, $pdflatex, $luala‐
2608 tex, and $xelatex, see the section "Advanced Configuration".
2609
2610
2611 %lualatex_input_extensions
2612 This variable specifies the extensions tried by latexmk when it
2613 finds that a lualatex run resulted in an error that a file has
2614 not been found, and the file is given without an extension.
2615 This typically happens when LaTeX commands of the form
2616 \input{file} or \includegraphics{figure}, when the relevant
2617 source file does not exist.
2618
2619 In this situation, latexmk searches for custom dependencies to
2620 make the missing file(s), but restricts it to the extensions
2621 specified by the variable %pdflatex_input_extensions. The
2622 default extensions are 'tex', 'pdf', 'jpg, and 'png'.
2623
2624 See details of the %latex_input_extensions for other information
2625 that equally applies to %lualatex_input_extensions.
2626
2627 $lualatex_silent_switch ["-interaction=batchmode"]
2628 Switch(es) for the lualatex program (specified in the variable
2629 $lualatex) when silent mode is on.
2630
2631 See details of the $latex_silent_switch for other information
2632 that equally applies to $lualatex_silent_switch.
2633
2634 $make ["make"]
2635 The make processing program.
2636
2637 $makeindex ["makeindex %O -o %D %S"]
2638 The index processing program.
2639
2640 $makeindex_silent_switch ["-q"]
2641 Switch(es) for the index processing program when silent mode is
2642 on.
2643
2644 $max_repeat [5]
2645 The maximum number of times latexmk will run *latex before
2646 deciding that there may be an infinite loop and that it needs to
2647 bail out, rather than rerunning *latex again to resolve cross-
2648 references, etc. The default value covers all normal cases.
2649
2650 (Note that the "etc" covers a lot of cases where one run of
2651 *latex generates files to be read in on a later run.)
2652
2653 $MSWin_back_slash [1]
2654 This configuration variable only has an effect when latexmk is
2655 running under MS-Windows. With the default value of 1 for this
2656 variable, when a command is executed under MS-Windows, latexmk
2657 substitutes "\" for the separator character between components
2658 of a directory name. Internally, latexmk uses "/" for the
2659 directory separator character, which is the character used by
2660 Unix-like systems.
2661
2662 For almost all programs and for almost all filenames under MS-
2663 Windows, both "\" and "/" are acceptable as the directory sepa‐
2664 rator character, provided at least that filenames are properly
2665 quoted. But it is possible that programs exist that only accept
2666 "\" on the command line, since that is the standard directory
2667 separator for MS-Windows. So for safety latexmk makes the sub‐
2668 stitution from "/" to "\", by default.
2669
2670 However there are also programs on MS-Windows for which a back
2671 slash "\" is interpreted differently than as a directory separa‐
2672 tor; for these the directory separator should be "/". Programs
2673 with this behavior include all the *latex programs in the
2674 TeXLive implementation (but not the MiKTeX implementation).
2675 Hence if you use TeXLive on MS-Windows, then $MSWin_back_slash
2676 should be set to zero.
2677
2678
2679 $new_viewer_always [0]
2680 This variable applies to latexmk only in continuous-preview
2681 mode. If $new_viewer_always is 0, latexmk will check for a pre‐
2682 viously running previewer on the same file, and if one is run‐
2683 ning will not start a new one. If $new_viewer_always is non-
2684 zero, this check will be skipped, and latexmk will behave as if
2685 no viewer is running.
2686
2687 $out_dir [""]
2688 If non-blank, this variable specifies the directory in which
2689 output files are to be written by a run of *latex. See also the
2690 variable $aux_dir.
2691
2692 The effect of this variable (when non-blank) is achieved by
2693 using the -output-directory option of *latex. This exists in
2694 the usual current (Dec. 2011 and later) implementations of TeX,
2695 i.e., MiKTeX and TeXLive. But it may not be present in other
2696 versions.
2697
2698 If you also use the -cd option, and $out_dir (or $aux_dir) con‐
2699 tains a relative path, then the path is interpreted relative to
2700 the document directory.
2701
2702 Commonly, the directory specified for output files is a subdi‐
2703 rectory of the current working directory. However, if you spec‐
2704 ify some other directory, e.g., "/tmp/foo" or "../output", be
2705 aware that this could cause problems, e.g., with makeindex or
2706 bibtex. This is because modern versions of these programs, by
2707 default, will refuse to work when they find that they are asked
2708 to write to a file in a directory that appears not to be the
2709 current working directory or one of its subdirectories. This is
2710 part of security measures by the whole TeX system that try to
2711 prevent malicious or errant TeX documents from incorrectly mess‐
2712 ing with a user's files. If for $out_dir or $aux_dir you really
2713 do need to specify an absolute pathname (e.g., "/tmp/foo") or a
2714 path (e.g., "../output") that includes a higher-level directory,
2715 and you need to use makeindex or bibtex, then you need to dis‐
2716 able the security measures (and assume any risks). One way of
2717 doing this is to temporarily set an operating system environment
2718 variable openout_any to "a" (as in "all"), to override the
2719 default "paranoid" setting.
2720
2721 $pdf_mode [0]
2722 If zero, do NOT generate a pdf version of the document. If
2723 equal to 1, generate a pdf version of the document using pdfla‐
2724 tex, using the command specified by the $pdflatex variable. If
2725 equal to 2, generate a pdf version of the document from the ps
2726 file, by using the command specified by the $ps2pdf variable.
2727 If equal to 3, generate a pdf version of the document from the
2728 dvi file, by using the command specified by the $dvipdf vari‐
2729 able. If equal to 4, generate a pdf version of the document
2730 using lualatex, using the command specified by the $lualatex
2731 variable. If equal to 5, generate a pdf version (and an xdv
2732 version) of the document using xelatex, using the commands spec‐
2733 ified by the $xelatex and xdvipdfmx variables.
2734
2735 In $pdf_mode=2, it is ensured that .dvi and .ps files are also
2736 made. In $pdf_mode=3, it is ensured that a .dvi file is also
2737 made. But this may be overridden by the document.
2738
2739 $pdflatex ["pdflatex %O %S"]
2740 Specifies the command line for the LaTeX processing program in a
2741 version that makes a pdf file instead of a dvi file.
2742
2743 An example use of this variable is to add certain options to the
2744 command line for the program, e.g.,
2745
2746 $pdflatex = "pdflatex --shell-escape %O %S";
2747
2748 (In some earlier versions of latexmk, you needed to use an
2749 assignment to $pdflatex to allow the use of lualatex or xelatex
2750 instead of pdflatex. There are now separate configuration vari‐
2751 ables for the use of lualatex or xelatex. See $lualatex and
2752 $xelatex.)
2753
2754 To do a coordinated setting of all of $latex, $pdflatex, $luala‐
2755 tex, and $xelatex, see the section "Advanced Configuration".
2756
2757 %pdflatex_input_extensions
2758 This variable specifies the extensions tried by latexmk when it
2759 finds that a pdflatex run resulted in an error that a file has
2760 not been found, and the file is given without an extension.
2761 This typically happens when LaTeX commands of the form
2762 \input{file} or \includegraphics{figure}, when the relevant
2763 source file does not exist.
2764
2765 In this situation, latexmk searches for custom dependencies to
2766 make the missing file(s), but restricts it to the extensions
2767 specified by the variable %pdflatex_input_extensions. The
2768 default extensions are 'tex', 'pdf', 'jpg, and 'png'.
2769
2770 See details of the %latex_input_extensions for other information
2771 that equally applies to %pdflatex_input_extensions.
2772
2773 $pdflatex_silent_switch ["-interaction=batchmode"]
2774 Switch(es) for the pdflatex program (specified in the variable
2775 $pdflatex) when silent mode is on.
2776
2777 See details of the $latex_silent_switch for other information
2778 that equally applies to $pdflatex_silent_switch.
2779
2780 $pdf_previewer ["start acroread %O %S"]
2781 The command to invoke a pdf-previewer.
2782
2783 On MS-Windows, the default is changed to "cmd /c start """;
2784 under more recent versions of Windows, this will cause to be run
2785 whatever command the system has associated with .pdf files. But
2786 this may be undesirable if this association is to acroread --
2787 see the notes in the explanation of the -pvc option.]
2788
2789 On OS-X the default is changed to "open %S", which results in
2790 OS-X starting up (and detaching) the viewer associated with the
2791 file. By default, for pdf files this association is to OS-X's
2792 preview, which is quite satisfactory.
2793
2794 WARNING: Problem under MS-Windows: if acroread is used as the
2795 pdf previewer, and it is actually viewing a pdf file, the pdf
2796 file cannot be updated. Thus makes acroread a bad choice of
2797 previewer if you use latexmk's previous-continuous mode (option
2798 -pvc) under MS-windows. This problem does not occur if, for
2799 example, SumatraPDF or gsview is used to view pdf files.
2800
2801 Important note: Normally you will want to have a previewer run
2802 detached, so that latexmk doesn't wait for the previewer to ter‐
2803 minate before continuing its work. So normally you should pre‐
2804 fix the command by "start ", which flags to latexmk that it
2805 should do the detaching of the previewer itself (by whatever
2806 method is appropriate to the operating system). But sometimes
2807 letting latexmk do the detaching is not appropriate (for a vari‐
2808 ety of non-trivial reasons), so you should put the "start " bit
2809 in yourself, whenever it is needed.
2810
2811 $pdf_update_command [""]
2812 When the pdf previewer is set to be updated by running a com‐
2813 mand, this is the command that is run. See the information for
2814 the variable $pdf_update_method.
2815
2816 $pdf_update_method [1 under UNIX, 3 under MS-Windows]
2817 How the pdf viewer updates its display when the pdf file has
2818 changed. See the information on the variable $dvi_update_method
2819 for the codes. (Note that information needs be changed slightly
2820 so that for the value 4, to run a command to do the update, the
2821 command is specified by the variable $pdf_update_command, and
2822 for the value 2, to specify update by signal, the signal is
2823 specified by $pdf_update_signal.)
2824
2825 Note that acroread under MS-Windows (but not UNIX) locks the pdf
2826 file, so the default value is then 3.
2827
2828 Arranging to use a command to get a previewer explicitly updated
2829 requires three variables to be set. For example:
2830
2831 $pdf_previewer = "start xpdf -remote %R %O %S";
2832 $pdf_update_method = 4;
2833 $pdf_update_command = "xpdf -remote %R -reload";
2834
2835 The first setting arranges for the xpdf program to be used in
2836 its "remote server mode", with the server name specified as the
2837 rootname of the TeX file. The second setting arranges for
2838 updating to be done in response to a command, and the third set‐
2839 ting sets the update command.
2840
2841 $pdf_update_signal [Under UNIX: SIGHUP, which is a system-dependent
2842 value]
2843 The number of the signal that is sent to the pdf viewer when it
2844 is updated by sending a signal -- see the information on the
2845 variable $pdf_update_method. The default value is the one
2846 appropriate for gv on a UNIX system.
2847
2848 $pid_position[1 under UNIX, -1 under MS-Windows]
2849 The variable $pid_position is used to specify which word in
2850 lines of the output from $pscmd corresponds to the process ID.
2851 The first word in the line is numbered 0. The default value of
2852 1 (2nd word in line) is correct for Solaris 2.6, Linux, and OS-X
2853 with their default settings of $pscmd.
2854
2855 Setting the variable to -1 is used to indicate that $pscmd is
2856 not to be used.
2857
2858 $postscript_mode [0]
2859 If nonzero, generate a postscript version of the document.
2860 Equivalent to the -ps option.
2861
2862 If some other request is made for which a postscript file is
2863 needed, then $postscript_mode will be set to 1.
2864
2865 $pre_tex_code ['']
2866
2867 Sets TeX code to be executed before inputting the source file.
2868 This works if the relevant one of $latex, etc contains a suit‐
2869 able command line with a %P or %U substitution. For example you
2870 could do
2871
2872 $latex = 'latex %O %P';
2873 $pre_tex_code = '\AtBeginDocument{An initial message\par}';
2874
2875 To set all of $latex, $pdflatex, $lualatex, and $xelatex you
2876 could use the subroutine alt_tex_cmds:
2877
2878 &alt_tex_cmds;
2879 $pre_tex_code = '\AtBeginDocument{An initial message\par}';
2880
2881
2882
2883 $preview_continuous_mode [0]
2884 If nonzero, run a previewer to view the document, and continue
2885 running latexmk to keep .dvi up-to-date. Equivalent to the -pvc
2886 option. Which previewer is run depends on the other settings,
2887 see the command line options -view=, and the variable $view.
2888
2889 $preview_mode [0]
2890 If nonzero, run a previewer to preview the document. Equivalent
2891 to the -pv option. Which previewer is run depends on the other
2892 settings, see the command line options -view=, and the variable
2893 $view.
2894
2895 $printout_mode [0]
2896 If nonzero, print the document using the command specified in
2897 the $lpr variable. Equivalent to the -p option. This is recom‐
2898 mended not to be set from an RC file, otherwise you could waste
2899 lots of paper.
2900
2901 $print_type = ["auto"]
2902 Type of file to printout: possibilities are "auto", "dvi",
2903 "none", "pdf", or "ps". See the option -print= for the meaning
2904 of the "auto" value.
2905
2906 $pscmd Command used to get all the processes currently run by the user.
2907 The -pvc option uses the command specified by the variable
2908 $pscmd to determine if there is an already running previewer,
2909 and to find the process ID (needed if latexmk needs to signal
2910 the previewer about file changes).
2911
2912 Each line of the output of this command is assumed to correspond
2913 to one process. See the $pid_position variable for how the
2914 process number is determined.
2915
2916 The default for pscmd is "NONE" under MS-Windows and cygwin
2917 (i.e., the command is not used), "ps -ww -u $ENV{USER}" under
2918 OS-X, and "ps -f -u $ENV{USER}" under other operating systems
2919 (including Linux). In these specifications "$ENV{USER}" is sub‐
2920 stituted by the username.
2921
2922 $ps2pdf ["ps2pdf %O %S %D"]
2923 Command to convert .ps to .pdf file.
2924
2925 $ps_filter [empty]
2926 The postscript file filter to be run on the newly produced post‐
2927 script file before other processing. Equivalent to specifying
2928 the -pF option.
2929
2930 $ps_previewer ["start gv %O %S", but start %O %S under MS-Windows]
2931 The command to invoke a ps-previewer. (The default under MS-
2932 Windows will cause to be run whatever command the system has
2933 associated with .ps files.)
2934
2935 Note that gv could be used with the -watch option updates its
2936 display whenever the postscript file changes, whereas ghostview
2937 does not. However, different versions of gv have slightly dif‐
2938 ferent ways of writing this option. You can configure this
2939 variable appropriately.
2940
2941 WARNING: Linux systems may have installed one (or more) versions
2942 of gv under different names, e.g., ggv, kghostview, etc, but
2943 perhaps not one actually called gv.
2944
2945 Important note: Normally you will want to have a previewer run
2946 detached, so that latexmk doesn't wait for the previewer to ter‐
2947 minate before continuing its work. So normally you should pre‐
2948 fix the command by "start ", which flags to latexmk that it
2949 should do the detaching of the previewer itself (by whatever
2950 method is appropriate to the operating system). But sometimes
2951 letting latexmk do the detaching is not appropriate (for a vari‐
2952 ety of non-trivial reasons), so you should put the "start " bit
2953 in yourself, whenever it is needed.
2954
2955
2956 $ps_previewer_landscape ["start gv -swap %O %S", but start %O %S under
2957 MS-Windows]
2958 The command to invoke a ps-previewer in landscape mode.
2959
2960 $ps_update_command [""]
2961 When the postscript previewer is set to be updated by running a
2962 command, this is the command that is run. See the information
2963 for the variable $ps_update_method.
2964
2965 $ps_update_method [0 under UNIX, 1 under MS-Windows]
2966 How the postscript viewer updates its display when the .ps file
2967 has changed. See the information on the variable
2968 $dvi_update_method for the codes. (Note that information needs
2969 be changed slightly so that for the value 4, to run a command to
2970 do the update, the command is specified by the variable
2971 $ps_update_command, and for the value 2, to specify update by
2972 signal, the signal is specified by $ps_update_signal.)
2973
2974 $ps_update_signal [Under UNIX: SIGHUP, which is a system-dependent
2975 value]
2976 The number of the signal that is sent to the pdf viewer when it
2977 is updated by sending a signal -- see $ps_update_method. The
2978 default value is the one appropriate for gv on a UNIX system.
2979
2980 $pvc_timeout [0]
2981 If this variable is nonzero, there will be a timeout in pvc
2982 mode after a period of inactivity. Inactivity means a period
2983 when latexmk has detected no file changes and hence has not
2984 taken any actions like compiling the document. The period of
2985 inactivity is in the variable $pvc_timeout_mins.
2986
2987
2988 $pvc_timeout_mins [30]
2989 The period of inactivity, in minutes, after which pvc mode times
2990 out. This is used if $pvc_timeout is nonzero.
2991
2992 $pvc_view_file_via_temporary [1]
2993 The same as $always_view_file_via_temporary, except that it only
2994 applies in preview-continuous mode (-pvc option).
2995
2996 $quote_filenames [1]
2997 This specifies whether substitutions for placeholders in command
2998 specifications (as in $pdflatex) are surrounded by double
2999 quotes. If this variable is 1 (or any other value Perl regards
3000 as true), then quoting is done. Otherwise quoting is omitted.
3001
3002 The quoting method used by latexmk is tested to work correctly
3003 under UNIX systems (including Linux and Mac OS-X) and under MS-
3004 Windows. It allows the use of filenames containing special
3005 characters, notably spaces. (But note that many versions of
3006 *latex cannot correctly deal with TeX files whose names contain
3007 spaces. Latexmk's quoting only ensures that such filenames are
3008 correctly treated by the operating system in passing arguments
3009 to programs.)
3010
3011 $recorder [1]
3012 Whether to use the -recorder option to (latex Use of this option
3013 results in a file of extension .fls containing a list of the
3014 files that these programs have read and written. Latexmk will
3015 then use this file to improve its detection of source files and
3016 generated files after a run of *latex.
3017
3018 It is generally recommended to use this option (or to configure
3019 the $recorder variable to be on.) But it only works if *latex
3020 supports the -recorder option, which is true for most current
3021 implementations
3022
3023 Note about the name of the .fls file: Most implementations of
3024 *latex produce an .fls file with the same basename as the main
3025 document's LaTeX, e.g., for Document.tex, the .fls file is Docu‐
3026 ment.fls. However, some implementations instead produce files
3027 named for the program, i.e., latex.fls or pdflatex.fls. In this
3028 second case, latexmk copies the latex.fls or pdflatex.fls to a
3029 file with the basename of the main LaTeX document, e.g., Docu‐
3030 ment.fls.
3031
3032 $search_path_separator [See below for default]
3033 The character separating paths in the environment variables TEX‐
3034 INPUTS, BIBINPUTS, and BSTINPUTS. This variable is mainly used
3035 by latexmk when the -outdir, -output-directory, -auxdir, and/or
3036 -aux-directory options are used. In that case latexmk needs to
3037 communicate appropriately modified search paths to bibtex,
3038 dvipdf, dvips, and *latex.
3039
3040 [Comment to technically savvy readers: *latex doesn't actually
3041 need the modified search path. But, surprisingly, dvipdf and
3042 dvips do, because sometimes graphics files get generated in the
3043 output or aux directories.]
3044
3045 The default under MSWin and Cygwin is ';' and under UNIX-like
3046 operating systems (including Linux and OS-X) is ':'. Normally
3047 the defaults give correct behavior. But there can be difficul‐
3048 ties if your operating system is of one kind, but some of your
3049 software is running under an emulator for the other kind of
3050 operating system; in that case you'll need to find out what is
3051 needed, and set $search_path_separator explicitly. (The same
3052 goes, of course, for unusual operating systems that are not in
3053 the MSWin, Linux, OS-X, Unix collection.)
3054
3055 $show_time [0]
3056 Whether to show CPU time used.
3057
3058 $silence_logfile_warnings [0]
3059 Whether after a run of *latex to summarize warnings in the log
3060 file about undefined citations and references. Setting
3061 $silence_logfile_warnings=0 gives the summary of warnings (pro‐
3062 vided silent mode isn't also set), and this is useful to locate
3063 undefined citations and references without searching through the
3064 much more verbose log file or the screen output of *latex. But
3065 the summary can also be excessively annoying. The default is
3066 not to give these warnings. The command line options
3067 -silence_logfile_warning_list and -silence_logfile_warning_list-
3068 also set this variable.
3069
3070 Note that multiple occurrences for the same undefined object on
3071 the same page and same line will be compressed to a single warn‐
3072 ing.
3073
3074 $silent [0]
3075 Whether to run silently. Setting $silent to 1 has the same
3076 effect as the -quiet of -silent options on the command line.
3077
3078 $sleep_time [2]
3079 The time to sleep (in seconds) between checking for source file
3080 changes when running with the -pvc option. This is subject to a
3081 minimum of one second delay, except that zero delay is also
3082 allowed.
3083
3084 A value of exactly 0 gives no delay, and typically results in
3085 100% CPU usage, which may not be desirable.
3086
3087 $texfile_search [""]
3088 This is an obsolete variable, replaced by the @default_files
3089 variable.
3090
3091 For backward compatibility, if you choose to set $tex‐
3092 file_search, it is a string of space-separated filenames, and
3093 then latexmk replaces @default_files with the filenames in $tex‐
3094 file_search to which is added "*.tex".
3095
3096 $success_cmd [undefined]
3097 See the documentation for $compiling_cmd.
3098
3099 $tmpdir [See below for default]
3100 Directory to store temporary files that latexmk may generate
3101 while running.
3102
3103 The default under MSWindows (including cygwin), is to set
3104 $tmpdir to the value of the first of whichever of the system
3105 environment variables TMPDIR or TEMP exists, otherwise to the
3106 current directory. Under other operating systems (expected to
3107 be UNIX/Linux, including OS-X), the default is the value of the
3108 system environment variable TMPDIR if it exists, otherwise
3109 "/tmp".
3110
3111 $use_make_for_missing_files [0]
3112 Whether to use make to try and make files that are missing after
3113 a run of *latex, and for which a custom dependency has not been
3114 found. This is generally useful only when latexmk is used as
3115 part of a bigger project which is built by using the make pro‐
3116 gram.
3117
3118 Note that once a missing file has been made, no further calls to
3119 make will be made on a subsequent run of latexmk to update the
3120 file. Handling this problem is the job of a suitably defined
3121 Makefile. See the section "USING latexmk WITH make" for how to
3122 do this. The intent of calling make from latexmk is merely to
3123 detect dependencies.
3124
3125 $view ["default"]
3126 Which kind of file is to be previewed if a previewer is used.
3127 The possible values are "default", "dvi", "ps", "pdf". The
3128 value of "default" means that the "highest" of the kinds of file
3129 generated is to be used (among .dvi, .ps and .pdf).
3130
3131
3132 $warnings_as_errors [0]
3133 Normally latexmk copies the behavior of latex in treating unde‐
3134 fined references and citations and multiply defined references
3135 as conditions that give a warning but not an error. The vari‐
3136 able $warnings_as_errors controls whether this behavior is modi‐
3137 fied.
3138
3139 When the variable is non-zero, latexmk at the end of its run
3140 will return a non-zero status code to the operating system if
3141 any of the files processed gives a warning about problems with
3142 citations or references (i.e., undefined citations or references
3143 or multiply defined references). This is after latexmk has com‐
3144 pleted all the runs it needs to try and resolve references and
3145 citations. Thus $warnings_as_errors being nonzero causes
3146 latexmk to treat such warnings as errors, but only when they
3147 occur on the last run of *latex and only after processing is
3148 complete. A non-zero value $warnings_as_errors can be set by
3149 the command-line option -Werror.
3150
3151 The default behavior is normally satisfactory in the usual edit-
3152 compile-edit cycle. But, for example, latexmk can also be used
3153 as part of a build process for some bigger project, e.g., for
3154 creating documentation in the build of a software application.
3155 Then it is often sensible to treat citation and reference warn‐
3156 ings as errors that require the overall build process to be
3157 aborted. Of course, since multiple runs of *latex are generally
3158 needed to resolve references and citations, what matters is not
3159 the warnings on the first run, but the warnings on the last run;
3160 latexmk takes this into account appropriately.
3161
3162 In addition, when preview-continuous mode is used, a non-zero
3163 value for $warnings_as_errors changes the use of the commands
3164 $failure_cmd, $warning_cmd, and $success_cmd after a complia‐
3165 tion. If there are citation or reference warnings, but no other
3166 errors, the behavior is as follows. If $warning_cmd is set, it
3167 is used. If it is not set, then then if $warnings_as_errors is
3168 non-zero and $failure_cmd is set, then $failure_cmd. Otherwise
3169 $success_cmd is used, if it is set. (The foregoing explanation
3170 is rather complicated, because latexmk has to deal with the case
3171 that one or more of the commands isn't set.)
3172
3173
3174 $xdvipdfmx ["xdvipdfmx -E -o %D %O %S"]
3175
3176 The program to make a pdf file from an xdv file (used in con‐
3177 junction with xelatex when $pdf_mode=5).
3178
3179 $xdvipdfmx_silent_switch ["-q"]
3180 Switch(es) for the xdvipdfmx program when silent mode is on.
3181
3182 $xelatex ["xelatex %O %S"]
3183 Specifies the command line for the LaTeX processing program of
3184 when the xelatex program is called for. See the documentation
3185 of the -xelatex option for some special properties of latexmk's
3186 use of xelatex.
3187
3188 Note about xelatex: latexmk uses xelatex to make an .xdv rather
3189 than .pdf file, with the .pdf file being created in a separate
3190 step. This is enforced by the use of the -no-pdf option. If %O
3191 is part of the command for invoking xelatex, then latexmk will
3192 insert the -no-pdf option automatically, otherwise you must pro‐
3193 vide the option yourself. See the documentation for the -pdfxe
3194 option for why latexmk makes a .xdv file rather than a .pdf file
3195 when xelatex is used.
3196
3197 To do a coordinated setting of all of $latex, $pdflatex, $luala‐
3198 tex, and $xelatex, see the section "Advanced Configuration".
3199
3200
3201 %xelatex_input_extensions
3202 This variable specifies the extensions tried by latexmk when it
3203 finds that an xelatex run resulted in an error that a file has
3204 not been found, and the file is given without an extension.
3205 This typically happens when LaTeX commands of the form
3206 \input{file} or \includegraphics{figure}, when the relevant
3207 source file does not exist.
3208
3209 In this situation, latexmk searches for custom dependencies to
3210 make the missing file(s), but restricts it to the extensions
3211 specified by the variable %xelatex_input_extensions. The
3212 default extensions are 'tex', 'pdf', 'jpg, and 'png'.
3213
3214 See details of the %latex_input_extensions for other information
3215 that equally applies to %xelatex_input_extensions.
3216
3217 $xelatex_silent_switch ["-interaction=batchmode"]
3218 Switch(es) for the xelatex program (specified in the variable
3219 $xelatex) when silent mode is on.
3220
3221 See details of the $latex_silent_switch for other information
3222 that equally applies to $xelatex_silent_switch.
3223
3224
3225
3226
3228 In any RC file a set of custom dependencies can be set up to convert a
3229 file with one extension to a file with another. An example use of this
3230 would be to allow latexmk to convert a .fig file to .eps to be included
3231 in the .tex file.
3232
3233
3234 Defining a custom dependency:
3235 The old method of configuring latexmk to use a custom dependency was to
3236 directly manipulate the @cus_dep_list array that contains information
3237 defining the custom dependencies. (See the section "Old Method of
3238 Defining Custom Dependencies" for details.) This method still works,
3239 but is no longer preferred.
3240
3241 A better method is to use the subroutines that allow convenient manipu‐
3242 lations of the custom dependency list. These are
3243
3244 add_cus_dep( fromextension, toextension, must, subroutine )
3245 remove_cus_dep( fromextension, toextension )
3246 show_cus_dep()
3247
3248 The arguments are as follows:
3249
3250 from extension:
3251 The extension of the file we are converting from (e.g. "fig").
3252 It is specified without a period.
3253
3254 to extension:
3255 The extension of the file we are converting to (e.g. "eps"). It
3256 is specified without a period.
3257
3258 must: If non-zero, the file from which we are converting must exist,
3259 if it doesn't exist latexmk will give an error message and exit
3260 unless the -f option is specified. If must is zero and the file
3261 we are converting from doesn't exist, then no action is taken.
3262 Generally, the appropriate value of must is zero.
3263
3264 function:
3265 The name of the subroutine that latexmk should call to perform
3266 the file conversion. The first argument to the subroutine is
3267 the base name of the file to be converted without any extension.
3268 The subroutines are declared in the syntax of Perl. The func‐
3269 tion should return 0 if it was successful and a nonzero number
3270 if it failed.
3271
3272
3273 Naturally add_cus_dep adds a custom dependency with the specified from
3274 and to extensions. If a custom dependency has been previously defined
3275 (e.g., in an rcfile that was read earlier), then it is replaced by the
3276 new one.
3277
3278 The subroutine remove_cus_dep removes the specified custom dependency.
3279 The subroutine show_cus_dep causes a list of the currently defined cus‐
3280 tom dependencies to be sent to the screen output.
3281
3282
3283 How custom dependencies are used:
3284 An instance of a custom dependency rule is created whenever latexmk
3285 detects that a run of *latex needs to read a file, like a graphics
3286 file, whose extension is the to-extension of a custom dependency. Then
3287 latexmk examines whether a file exists with the same name, but with the
3288 corresponding from-extension, as specified in the custom-dependency.
3289 If it does, then a corresponding instance of the custom dependency is
3290 created, after which the rule is invoked whenever the destination file
3291 (the one with the to-extension) is out-of-date with respect to the cor‐
3292 responding source file.
3293
3294 To make the new destination file, the Perl subroutine specified in the
3295 rule is invoked, with an argument that is the base name of the files in
3296 question. Simple cases just involve a subroutine invoking an external
3297 program; this can be done by following the templates below, even by
3298 those without knowledge of the Perl programming language. Of course,
3299 experts could do something much more elaborate.
3300
3301 One item in the specification of each custom-dependency rule, labeled
3302 "must" above, specifies how the rule should be applied when the source
3303 file fails to exist.
3304
3305 When latex reports that an input file (e.g., a graphics file) does not
3306 exist, latexmk tries to find a source file and a custom dependency that
3307 can be used to make it. If it succeeds, then it creates an instance of
3308 the custom dependency and invokes it to make the missing file, after
3309 which the next pass of latex etc will be able to read the newly created
3310 file.
3311
3312 Note for advanced usage: The operating system's environment variable
3313 TEXINPUTS can be used to specify a search path for finding files by
3314 latex etc. Correspondingly, when a missing file is reported, latexmk
3315 looks in the directories specified in TEXINPUTS as well as in the cur‐
3316 rent directory, to find a source file from which an instance of a cus‐
3317 tom dependency can be used to make the missing file.
3318
3319
3320 Function to implement custom dependency, traditional method:
3321 The function that implements a custom dependency gets the information
3322 on the files to be processed in two ways. The first is through its one
3323 argument; the argument contains the base name of the source and desti‐
3324 nation files. The second way is described later.
3325
3326 A simple and typical example of code in an initialization rcfile using
3327 the first method is:
3328
3329 add_cus_dep( 'fig', 'eps', 0, 'fig2eps' );
3330 sub fig2eps {
3331 system( "fig2dev -Leps \"$_[0].fig\" \"$_[0].eps\"" );
3332 }
3333
3334 The first line adds a custom dependency that converts a file with
3335 extension "fig", as created by the xfig program, to an encapsulated
3336 postscript file, with extension "eps". The remaining lines define a
3337 subroutine that carries out the conversion. If a rule for converting
3338 "fig" to "eps" files already exists (e.g., from a previously read-in
3339 initialization file), the latexmk will delete this rule before making
3340 the new one.
3341
3342 Suppose latexmk is using this rule to convert a file "figure.fig" to
3343 "figure.eps". Then it will invoke the fig2eps subroutine defined in
3344 the above code with a single argument "figure", which is the basename
3345 of each of the files (possibly with a path component). This argument
3346 is referred to by Perl as $_[0]. In the example above, the subroutine
3347 uses the Perl command system to invoke the program fig2dev. The double
3348 quotes around the string are a Perl idiom that signify that each string
3349 of the form of a variable name, $_[0] in this case, is to be substi‐
3350 tuted by its value.
3351
3352 If the return value of the subroutine is non-zero, then latexmk will
3353 assume an error occurred during the execution of the subroutine. In
3354 the above example, no explicit return value is given, and instead the
3355 return value is the value returned by the last (and only) statement,
3356 i.e., the invocation of system, which returns the value 0 on success.
3357
3358 If you use pdflatex, lualatex or xelatex instead of latex, then you
3359 will probably prefer to convert your graphics files to pdf format, in
3360 which case you would replace the above code in an initialization file
3361 by
3362
3363 add_cus_dep( 'fig', 'pdf, 0, 'fig2pdf' );
3364 sub fig2pdf {
3365 system( "fig2dev -Lpdf \"$_[0].fig\" \"$_[0].pdf\"" );
3366 }
3367
3368 Note 1: In the command lines given in the system commands in the above
3369 examples, double quotes have been inserted around the file names
3370 (implemented by '\"' in the Perl language). They immunize the running
3371 of the program against special characters in filenames. Very often
3372 these quotes are not necessary, i.e., they can be omitted. But it is
3373 normally safer to keep them in. Even though the rules for quoting vary
3374 between operating systems, command shells and individual pieces of
3375 software, the quotes in the above examples do not cause problems in the
3376 cases I have tested.
3377
3378 Note 2: One case in which the quotes are important is when the files
3379 are in a subdirectory and your operating system is Microsoft Windows.
3380 Then the separator character for directory components can be either a
3381 forward slash '/' or Microsoft's more usual backward slash ´\'. For‐
3382 ward slashes are generated by latexmk, to maintain its sanity from
3383 software like MiKTeX that mixes both directory separators; but their
3384 correct use normally requires quoted filenames. (See a log file from a
3385 run of MiKTeX (at least in v. 2.9) for an example of the use of both
3386 directory separators.)
3387
3388 Note 3: The subroutines implementing custom dependencies in the exam‐
3389 ples given just have a single line invoking an external program.
3390 That's the usual situation. But since the subroutines are in the Perl
3391 language, you can implement much more complicated processing if you
3392 need it.
3393
3394
3395 Removing custom dependencies, and when you might need to do this:
3396 If you have some general custom dependencies defined in the system or
3397 user initialization file, you may find that for a particular project
3398 they are undesirable. So you might want to delete the unneeded ones.
3399 A situation where this would be desirable is where there are multiple
3400 custom dependencies with the same from-extension or the same to-exten‐
3401 sion. In that case, latexmk might choose a different one from the one
3402 you want for a specific project. As an example, to remove any "fig" to
3403 "eps" rule you would use:
3404
3405 remove_cus_dep( 'fig', 'eps' );
3406
3407 If you have complicated sets of custom dependencies, you may want to
3408 get a listing of the custom dependencies. This is done by using the
3409 line
3410
3411 show_cus_dep();
3412
3413 in an initialization file.
3414
3415
3416 Function implementing custom dependency, alternative methods:
3417 So far the examples for functions to implement custom dependencies have
3418 used the argument of the function to specify the base name of converted
3419 file. This method has been available since very old versions of
3420 latexmk, and many examples can be found, e.g., on the web.
3421
3422 However in later versions of latexmk the internal structure of the
3423 implementation of its "rules" for the steps of processing, including
3424 custom dependencies, became much more powerful. The function imple‐
3425 menting a custom dependency is executed within a special context where
3426 a number of extra variables and subroutines are defined. Publicly doc‐
3427 umented ones, intended to be long-term stable, are listed below, under
3428 the heading "Variables and subroutines for processing a rule".
3429
3430 Examples of their use is given in the following examples, concerning
3431 multiple index files and glossaries.
3432
3433 The only index-file conversion built-in to latexmk is from an ".idx"
3434 file written on one run of *latex to an ".ind" file to be read in on a
3435 subsequent run. But with the index.sty package, for example, you can
3436 create extra indexes with extensions that you configure. Latexmk does
3437 not know how to deduce the extensions from the information it has. But
3438 you can easily write a custom dependency. For example if your latex
3439 file uses the command "\newindex{special}{ndx}{nnd}{Special index}" you
3440 will need to get latexmk to convert files with the extension .ndx to
3441 .nnd. The most elementary method is to define a custom dependency as
3442 follows:
3443
3444 add_cus_dep( 'ndx', 'nnd', 0, 'ndx2nnd' );
3445 sub ndx2nnd {
3446 return system( "makeindex -o \"$_[0].nnd\" \"$_[0].ndx\"" );
3447 }
3448 push @generated_exts, 'ndx', 'nnd';
3449
3450 Notice the added line compared with earlier examples. The extra line
3451 gets the extensions "ndx" and "nnd" added to the list of extensions for
3452 generated files; then the extra index files will be deleted by clean-up
3453 operations
3454
3455 But if you have yet more indexes with yet different extensions, e.g.,
3456 "adx" and "and", then you will need a separate function for each pair
3457 of extensions. This is quite annoying. You can use the Run_subst
3458 function to simplify the definitions to use a single function:
3459
3460 add_cus_dep( 'ndx', 'nnd', 0, 'dx2nd' );
3461 add_cus_dep( 'adx', 'and', 0, 'dx2nd' );
3462 sub dx2nd {
3463 return Run_subst( "makeindex -o %D %S" );
3464 }
3465 push @generated_exts, 'ndx', 'nnd', 'adx', 'and';
3466
3467 You could also instead use
3468
3469 add_cus_dep( 'ndx', 'nnd', 0, 'dx2nd' );
3470 add_cus_dep( 'adx', 'and', 0, 'dx2nd' );
3471 sub dx2nd {
3472 return Run_subst( $makeindex );
3473 }
3474 push @generated_exts, 'ndx', 'nnd', 'adx', 'and';
3475
3476 This last example uses the command specification in $makeindex, and so
3477 any customization you have made for the standard index also applies to
3478 your extra indexes.
3479
3480 Similar techniques can be applied for glossaries.
3481
3482 Those of you with experience with Makefiles, may get concerned that the
3483 .ndx file is written during a run of *latex and is always later than
3484 the .nnd last read in. Thus the .nnd appears to be perpetually out-of-
3485 date. This situation, of circular dependencies, is endemic to latex,
3486 and is one of the issues that latexmk is programmed to overcome. It
3487 examines the contents of the files (by use of a checksum), and only
3488 does a remake when the file contents have actually changed.
3489
3490 Of course if you choose to write random data to the .nnd (or the .aux
3491 file, etc) that changes on each new run, then you will have a problem.
3492 For real experts: See the %hash_calc_ignore_pattern if you have to deal
3493 with such problems.
3494
3495
3496 Old Method of Defining Custom Dependencies:
3497 In much older versions of latexmk, the only method of defining custom
3498 dependencies was to directly manipulate the table of custom dependen‐
3499 cies. This is contained in the @cus_dep_list array. It is an array of
3500 strings, and each string in the array has four items in it, each sepa‐
3501 rated by a space, the from-extension, the to-extension, the "must"
3502 item, and the name of the subroutine for the custom dependency. These
3503 were all defined above.
3504
3505 An example of the old method of defining custom dependencies is as fol‐
3506 lows. It is the code in an RC file to ensure automatic conversion of
3507 .fig files to .eps files:
3508
3509 push @cus_dep_list, "fig eps 0 fig2eps";
3510 sub fig2eps {
3511 return system( "fig2dev -Lps \"$_[0].fig\" \"$_[0].eps\"" );
3512 }
3513
3514 This method still works, and is almost equivalent to the code given
3515 earlier that used the add_cus_dep subroutine. However, the old method
3516 doesn't delete any previous custom-dependency for the same conversion.
3517 So the new method is preferable.
3518
3519
3520
3522 For most purposes, simple configuration for latexmk along the lines of
3523 the examples given is sufficient. But sometimes you need something
3524 harder. In this section, I indicate some extra possibilities. Gener‐
3525 ally to use these, you need to be fluent in the Perl language, since
3526 this is what is used in the rc files.

3534 Utility subroutines
3535 ensure_path( var, values ...)
3536
3537 The first parameter is the name of one of the system's environ‐
3538 ment variables for search paths. The remaining parameters are
3539 values that should be in the variable. For each of the value
3540 parameters, if it isn't already in the variable, then it is
3541 prepended to the variable; in that case the environment variable
3542 is created if it doesn't already exist. For separating values,
3543 the character appropriate the the operating system is used --
3544 see the configuration variable $search_path_separator.
3545
3546 Example:
3547
3548 ensure_path( 'TEXINPUTS', './custom_cls_sty_files//' );
3549
3550 (In this example, the trailing '//' is documented by TeX systems
3551 to mean that *latex search for files in the specified directory
3552 and in all subdirectories.)
3553
3554 Technically ensure_path works by setting Perl's variable
3555 $ENV{var}, where var is the name of the target variable. The
3556 changed value is then passed as an environment variable to any
3557 invoked programs.
3558
3559
3560 Variables and subroutines for processing a rule
3561 A step in the processing is called a rule. One possibility to implement
3562 the processing of a rule is by a Perl subroutine. This is always the
3563 case for custom dependencies. Also, for any other rule, you can use a
3564 subroutine by prefixing the command specification by the word "inter‐
3565 nal" -- see the section FORMAT OF COMMAND SPECIFICATIONS.
3566
3567 When you use a subroutine for processing a rule, all the possibilities
3568 of Perl programming are available, of course. In addition, some of
3569 latexmk's internal variables and subroutines are available. The ones
3570 listed below are intended to be available to (advanced) users, and
3571 their specifications will generally have stability under upgrades. Gen‐
3572 erally, the variables should be treated as read-only: Changing their
3573 values can have bad consequences, since it is liable to mess up the
3574 consistency of what latexmk is doing.
3575
3576 $rule This variable has the name of the rule, as known to latexmk.
3577 Note that the exact contents of this variable for a given rule
3578 may be dependent on the version of latexmk
3579
3580 $$Psource
3581 This gives the name of the primary source file. Note the double
3582 dollar signs.
3583
3584 $$Pdest
3585 This gives the name of the main output file if any. Note the
3586 double dollar signs.
3587
3588 rdb_ensure_file( $rule, file )
3589 This a subroutine that ensures that the given file is among the
3590 source files for the specified rule. It is typically used when,
3591 during the processing of a rule, it is known that a particular
3592 extra file is among the dependencies that latexmk should know,
3593 but its default methods don't find the dependency. Almost always
3594 the first argument is the name of the rule currently being pro‐
3595 cessed, so it is then appropriate to specify it by $rule.
3596
3597 For examples of its use, see some of the files in the directory
3598 example_rcfiles of latexmk's distribution. Currently the cases
3599 that use this subroutine are bib2gls-latexmkrc, excel‐
3600 tex_latexmkrc and texinfo-latexmkrc. These illustrate typical
3601 cases where latexmk's normal processing fails to detect certain
3602 extra source files.
3603
3604 rdb_remove_files( $rule, file, ... )
3605 This subroutine removes one or more files from the dependency
3606 list for the given rule.
3607
3608 rdb_list_source( $rule )
3609 This subroutine returns the list of source files (i.e., the
3610 dependency list) for the given rule.
3611
3612 rdb_set_source( $rule, file, ... )
3613
3614 rdb_set_source( $rule, @files )
3615 This subroutine sets the dependency list for the given rule to
3616 be the specified files. Files that are already in the list have
3617 unchanged information. Files that were not in the list are
3618 added to it. Files in the previous dependency list that are not
3619 in the newly specified list of files are removed from the depen‐
3620 dency list.
3621
3622 Run_subst( command_spec )
3623 This subroutine runs the command specified by command_spec. The
3624 specification is a string in the format listed in the section
3625 "Format of Command Specifications". An important action of the
3626 Run_subst is to make substitutions of placeholders, e.g., %S and
3627 %D for source and destination files; these get substituted
3628 before the command is run. In addition, the command after sub‐
3629 stitution is printed to the screen unless latexmk is running in
3630 silent mode.
3631
3632
3633 Coordinated Setting of Commands for *latex
3634 To set all of $latex, $pdflatex, $lualatex, and $xelatex to a common
3635 pattern, you can use one of the following subroutines, std_tex_cmds,
3636 alt_tex_cmds, and set_tex_cmds.
3637
3638 They work as follows
3639
3640 &std_tex_cmds;
3641
3642 This results in $latex = 'latex %O %S', and similarly for $pdflatex,
3643 $lualatex, and $xelatex. Note the ampersand in the invocation; this
3644 indicates to Perl that a subroutine is being called.
3645
3646 &alt_tex_cmds;
3647
3648 This results in $latex = 'latex %O %P', and similarly for $pdflatex,
3649 $lualatex, and $xelatex. Note the ampersand in the invocation; this
3650 indicates to Perl that a subroutine is being called.
3651
3652 set_tex_cmds( CMD_SPEC );
3653
3654 Here CMD_SPEC is the command line without the program name. This
3655 results in $latex = 'CMD_SPEC', and similarly for $pdflatex, $lualatex,
3656 and $xelatex. An example would be
3657
3658 set_tex_cmds( '--interaction=batchmode %O %S' );
3659
3660
3661 Advanced configuration: Using latexmk with make
3662 This section is targeted only at advanced users who use the make pro‐
3663 gram for complex projects, as for software development, with the depen‐
3664 dencies specified by a Makefile.
3665
3666 Now the basic task of latexmk is to run the appropriate programs to
3667 make a viewable version of a LaTeX document. However, the usual make
3668 program is not suited to this purpose for at least two reasons. First
3669 is that the use of LaTeX involves circular dependencies (e.g., via .aux
3670 files), and these cannot be handled by the standard make program. Sec‐
3671 ond is that in a large document the set of source files can change
3672 quite frequently, particularly with included graphics files; in this
3673 situation keeping a Makefile manually updated is inappropriate and
3674 error-prone, especially when the dependencies can be determined auto‐
3675 matically. Latexmk solves both of these problems robustly.
3676
3677 Thus for many standard LaTeX documents latexmk can be used by itself
3678 without the make program. In a complex project it simply needs to be
3679 suitably configured. A standard configuration would be to define cus‐
3680 tom dependencies to make graphics files from their source files (e.g.,
3681 as created by the xfig program). Custom dependencies are latexmk's
3682 equivalent of pattern rules in Makefiles.
3683
3684 Nevertheless there are projects for which a Makefile is appropriate,
3685 and it is useful to know how to use latexmk from a Makefile. A typical
3686 example would be to generate documentation for a software project.
3687 Potentially the interaction with the rest of the rules in the Makefile
3688 could be quite complicated, for example if some of the source files for
3689 a LaTeX document are generated by the project's software.
3690
3691 In this section, I give a couple of examples of how latexmk can be use‐
3692 fully invoked from a Makefile. The examples use specific features of
3693 current versions of GNU make, which is the default on both linux and
3694 OS-X systems. They may need modifications for other versions of make.
3695
3696 The simplest method is simply to delegate all the relevant tasks to
3697 latexmk, as is suitable for a straightforward LaTeX document. For this
3698 a suitable Makefile is like
3699
3700 .PHONY : FORCE_MAKE
3701 all : try.pdf
3702 %.pdf : %.tex FORCE_MAKE
3703 latexmk -pdf -dvi- -ps- $<
3704
3705 (Note: the last line must be introduced by a tab for the Makefile to
3706 function correctly!) Naturally, if making try.pdf from its associated
3707 LaTeX file try.tex were the only task to be performed, a direct use of
3708 latexmk without a Makefile would normally be better. The benefit of
3709 using a Makefile for a LaTeX document would be in a larger project,
3710 where lines such as the above would be only be a small part of a larger
3711 Makefile.
3712
3713 The above example has a pattern rule for making a .pdf file from a .tex
3714 file, and it is defined to use latexmk in the obvious way. There is a
3715 conventional default target named "all", with a prerequisite of
3716 try.pdf. So when make is invoked, by default it makes try.pdf. The
3717 only complication is that there may be many source files beyond
3718 try.tex, but these aren't specified in the Makefile, so changes in them
3719 will not by themselves cause latexmk to be invoked. Instead, the pat‐
3720 tern rule is equipped with a "phony" prerequisite FORCE_MAKE; this has
3721 the effect of causing the rule to be always out-of-date, so that
3722 latexmk is always run. It is latexmk that decides whether any action
3723 is needed, e.g., a rerun of pdflatex. Effectively the Makefile dele‐
3724 gates all decisions to latexmk, while make has no knowledge of the list
3725 of source files except for primary LaTeX file for the document. If
3726 there are, for example, graphics files to be made, these must be made
3727 by custom dependencies configured in latexmk.
3728
3729 But something better is needed in more complicated situations, for
3730 example, when the making of graphics files needs to be specified by
3731 rules in the Makefile. To do this, one can use a Makefile like the
3732 following:
3733
3734 TARGETS = document1.pdf document2.pdf
3735 DEPS_DIR = .deps
3736 LATEXMK = latexmk -recorder -use-make -deps \
3737 -e 'warn qq(In Makefile, turn off custom dependencies\n);' \
3738 -e '@cus_dep_list = ();' \
3739 -e 'show_cus_dep();'
3740 all : $(TARGETS)
3741 $(foreach file,$(TARGETS),$(eval -include $(DEPS_DIR)/$(file)P))
3742 $(DEPS_DIR) :
3743 mkdir $@
3744 %.pdf : %.tex
3745 if [ ! -e $(DEPS_DIR) ]; then mkdir $(DEPS_DIR); fi
3746 $(LATEXMK) -pdf -dvi- -ps- -deps-out=$(DEPS_DIR)/$@P $<
3747 %.pdf : %.fig
3748 fig2dev -Lpdf $< $@
3749
3750 (Again, the lines containing the commands for the rules should be
3751 started with tabs.) This example was inspired by how GNU automake han‐
3752 dles automatic dependency tracking of C source files.
3753
3754 After each run of latexmk, dependency information is put in a file in
3755 the .deps subdirectory. The Makefile causes these dependency files to
3756 be read by make, which now has the full dependency information for each
3757 target .pdf file. To make things less trivial it is specificed that
3758 two files document1.pdf and document2.pdf are the targets. The depen‐
3759 dency files are .deps/document1.pdfP and .deps/document2.pdfP.
3760
3761 There is now no need for the phony prerequisite for the rule to make
3762 .pdf files from .tex files. But I have added a rule to make .pdf files
3763 from .fig files produced by the xfig program; these are commonly used
3764 for graphics insertions in LaTeX documents. Latexmk is arranged to
3765 output a dependency file after each run. It is given the -recorder
3766 option, which improves its detection of files generated during a run of
3767 pdflatex; such files should not be in the dependency list. The -e
3768 options are used to turn off all custom dependencies, and to document
3769 this. Instead the -use-make is used to delegate the making of missing
3770 files to make itself.
3771
3772 Suppose in the LaTeX file there is a command \includegraphics{graph},
3773 and an xfig file "graph.fig" exists. On a first run, pdflatex reports
3774 a missing file, named "graph". Latexmk succeeds in making "graph.pdf"
3775 by calling "make graph.pdf", and after completion of its work, it lists
3776 "fig.pdf" among the dependents of the file latexmk is making. Then let
3777 "fig.fig" be updated, and then let make be run. Make first remakes
3778 "fig.pdf", and only then reruns latexmk.
3779
3780 Thus we now have a method by which all the subsidiary processing is
3781 delegated to make.
3782
3783
3785 latex(1), bibtex(1), lualatex(1), pdflatex(1), xelatex(1).
3786
3788 Sometimes a viewer (gv) tries to read an updated .ps or .pdf file after
3789 its creation is started but before the file is complete. Work around:
3790 manually refresh (or reopen) display. Or use one of the other preview‐
3791 ers and update methods.
3792
3793 (The following isn't really a bug, but concerns features of preview‐
3794 ers.) Preview continuous mode only works perfectly with certain pre‐
3795 viewers: Xdvi on UNIX/Linux works for dvi files. Gv on UNIX/Linux
3796 works for both postscript and pdf. Ghostview on UNIX/Linux needs a
3797 manual update (reopen); it views postscript and pdf. Gsview under MS-
3798 Windows works for both postscript and pdf, but only reads the updated
3799 file when its screen is refreshed. Acroread under UNIX/Linux views
3800 pdf, but the file needs to be closed and reopened to view an updated
3801 version. Under MS-Windows, acroread locks its input file and so the
3802 pdf file cannot be updated. (Remedy: configure latexmk to use suma‐
3803 trapdf instead.)
