For our purposes here, we +identify two classes of generated file. + +One class is what one may term the final output files, for example, +the .pdf file generated by running pdflatex, or the .dvi file from +latex. Also in this class is the ps file generated by applying dvips to +a .dvi file. There are also .synctec or .synctex.gz files that can be used +by programs that display .pdf files and the like to relate positions in +them to positions in source files. + +The second class of file is composed of all other generated files: These +include notably .aux files that are used for implementing cross referencing, +and are both generated on one run and read on a later run. Many packages +generate yet more such intermediate files, as well as programs like bibtex, +makeindex, etc. There are also .log files from *latex and corresponding +files from other programs. + +Let us use the term "output directory" for the directory that receives the +final output files, and "aux directory" for the directory for the other +generated files. If no special options are provided to the *latex +programs, these directories default to the current directory, and then the +generated files aren't segregated. If the two directories are the same, as +is the simplest situation, then all generated files are written to the same +directory, and one often simply refers to the output directory, without +mentioning a separate aux directory. + +Support for them is provided for them in the *latex programs: by the single +option \fB-output-directory\fR for the TeXLive implementations, and by the +options \fB-aux-directory\fR and \fB-output-directory\fR for the MiKTeX +implementations. Special support like this is needed for two reasons: +First is that there are many packages that write files and it needs to be +arranged that these are automatically written to the appropriate directory +without any rewriting of the packages' code. Second is that the files are +often read in again on subsequent runs of *latex, and it is necessary that +the program knows where to find the files. + +A complication is that the TeXLive implementation does not allow for +separate aux and output directories. Latexmk deals with this by being able +to emulating a separate aux directory: In this method it invokes *latex +with just an \fB-output-directory\fR option, with the directory set not to +the desired output directory, but to the aux directory. After running +*latex, it moves the relevant final output file(s) to the intended output +directory. Emulation can be turned on by setting the configuration +variable \fI$emulate_aux\fR to one in a configuration file or by using +latexmk's \fB-emulate-aux-dir\fR option. The emulation method works +equally well if MiKTeX is used. + +Latexmk also turns emulation on if it is found to be needed, as follows. +Suppose emulation is initially off, but the aux and output directories are +different. Then latexmk invokes *latex with an -aux-directory option and +after the run finds that it hasn't been obeyed, notably because the .log +file is in the output directory rather than the aux directory. Latexmk +then sets emulation on, and retries. Conceivably, it could move all the +appropriate generated files from the output directory to the aux directory; +but there is such a large variety of possibilities for these files that +this is hard to identify all of them reliably except for simple cases. + +Note that the emulation issue only arises when the user has arranged for +the the aux and output directories to be different. When instead they are +equal, e.g., because the user only set the \fI$out_dir\fR variable, then +latexmk invokes *latex with only an \fB-output-directory\fR option, which +works as intended with both TeXLive and MiKTeX. + +In addition, latexmk arranges the invocations of any auxiliary programs +like bibtex and makeindex so that they will read and write the relevant +files from and to the aux directory. Programs like dvips, dvipdf, ps2pdf, +and xdvipdfmx are invoked so that they read from the appropriate places and +write their output to the output directory. + +\fIFiles considered as final output files, i.e., those that belong in the +output directory rather than the aux directory\fR: These have the +extensions .dvi, .ps., .pdf, .synctex, and .synctex.gz. +A special case, because of compatibility issues, is of .fls files: See +below. + +Note that xelatex when invoked with its \fB-no-pdf\fR option, as latexmk +does, generates an .xdv file, which would appear to have the same status as +a .dvi file generated by latex. Nevertheless, latexmk treats .xdv as an +intermediate file that is found in the aux directory. This is to match +MiKTeX's treatment of the \fB-aux-directory\fR option. As further +justification, one can say that under modern conditions an .xdv file is +(almost) always an intermediate file. Historically, the situation +with .dvi files from latex was different, and currently dvi previewers do +exist. + + +\fIVariables and options for directories\fR: The variables for setting the +aux and output directories are \fI$aux_dir\fR and \fI$out_dir\fR, with +corresponding command line options \fB-auxdir\fR (or \fB-aux-directory\fR) +and \fB-outdir\fR (or \fB-output-directory\fR). When a value for these is +blank (which is the default value), it implies the use of a default: For +the aux directory, the default is to set it equal to the output directory. +For the output directory, the default is to be the current directory. + +For the turning on and off of the emulation mode, there is the +configuration variable \fI$emulate_aux\fR and the options +\fB-emulate-aux-dir\fR, \fB-emulate-aux-dir-\fR, \fB-noemulate-aux-dir\fR. + + +\fIInteraction with -cd option\fR: When the \fB-cd\fR option is used (or +the equivalent setting of \fI$do_cd\fR variable), then latexmk changes the +working directory to the document directory before invoking *latex. If the +aux and/or output directories are given by relative paths, e.g., by +\fB-outdir=output\fR for a directory named "output", then the directories +are relative to the document directory, rather than relative to the working +directory that was in effect when latexmk was invoked. This matches the +behavior of *latex as invoked with the provided command line directory +argument(s) after the change of working directory to the document +directory. + +\fIAutomatic creation of aux and output directories\fR: Unlike *latex, if +latexmk finds the requested directory/ies don't exist, it creates it/them, +thereby avoiding errors when *latex is invoked. + +If the document uses the \\include macro to read a .tex file from a +subdirectory, *latex will attempt to write an extra aux file to the +corresponding subdirectory of the aux directory. If the subdirectory +doesn't exist, then *latex will complain that it can't write the aux file. +After the run of *latex, latexmk detects this situation, creates the +necessary directory, and reruns *latex with the error situation corrected. + +\fIChoice of aux and output directories\fR: Often the aux +and output directories are given as subdirectories of the document +directory, e.g., by \fB-outdir=output\fR. But it is possible to provide, +for example, an absolute path or a path relative to a parent directory, +e.g., "/tmp/foo" or "../output". Be aware that in general this can cause +problems, notably with \fImakeindex\fR or \fIbibtex\fR. This is because +modern versions of these programs, by default, will refuse to work when +they find that they are asked to write to a file in a directory that +appears not to be the current working directory or one of its +subdirectories. This is part of security measures by the whole TeX system +that try to prevent malicious or errant TeX documents from incorrectly +messing with a user's files. + +By default, latexmk evades this issue: Before running bibtex and makeindex, +latexmk changes working directory to the aux directory, with appropriate +settings of search paths. The use or non-use of this trick is governed by +the variables \fI$bibtex_fudge\fR and \fI$makeindex_fudge\fR. +Unfortunately, the trick sometimes makes bibtex and makeindex unable to +find files. + +If necessary the trick can be turned off. But this is incompatible with an +aux directory like, "/tmp/foo" of "../output"). If you really have to deal +with this situation, and only if you have to deal with it, then you need to +disable the security measures (and assume any risks). One way of doing +this is to temporarily set an operating system environment variable +openout_any to "a" (as in "all"), to override the default "paranoid" +setting. + +\fICertain names of aux and output directories not allowed on Microsoft +Windows\fR: It is natural to want to use the name "aux" for the aux +directory, e.g., by using the option \fB-auxdir=aux\fR. But on Microsoft +operating systems "aux" is one of the names that is not allowed for a file +or directory. I find it useful to standardize on a name like "auxdir" +(e.g., by \fB-auxdir=auxdir\fR); this works independently of operating +system. + +\fILocation of .fls file\fR: Much of the dependency information that +latexmk uses comes from the .fls file generated when *latex is invoked with +the \fB-recorder\fR option, which latexmk does by default. It may seem +rational that this is written to the aux directory. But in fact versions +of MiKTeX prior to Oct. 2020 wrote it to the output directory. Later +versions do write it to the aux directory. To deal with this, latexmk does +two things: First, if latexmk finds that the .fls file has only been +generated in the "wrong" directory, then latexmk copies it to the expected +directory, after which latexmk's operation continues correctly +independently of the behavior of *latex. Second it allows its idea of the +"correct" (or expected) directory to be configured by the variable +\fI$fls_uses_aux_dir\fR.

For our + purposes here, we identify two classes of generated file. + + One class is what one may term the final output files, for example, the + .pdf file generated by running pdflatex, or the .dvi file from latex. + Also in this class is the ps file generated by applying dvips to a .dvi + file. There are also .synctec or .synctex.gz files that can be used by + programs that display .pdf files and the like to relate positions in + them to positions in source files. + + The second class of file is composed of all other generated files: + These include notably .aux files that are used for implementing cross + referencing, and are both generated on one run and read on a later run. + Many packages generate yet more such intermediate files, as well as + programs like bibtex, makeindex, etc. There are also .log files from + *latex and corresponding files from other programs. + + Let us use the term "output directory" for the directory that receives + the final output files, and "aux directory" for the directory for the + other generated files. If no special options are provided to the *la- + tex programs, these directories default to the current directory, and + then the generated files aren't segregated. If the two directories are + the same, as is the simplest situation, then all generated files are + written to the same directory, and one often simply refers to the out- + put directory, without mentioning a separate aux directory. + + Support for them is provided for them in the *latex programs: by the + single option -output-directory for the TeXLive implementations, and by + the options -aux-directory and -output-directory for the MiKTeX imple- + mentations. Special support like this is needed for two reasons: First + is that there are many packages that write files and it needs to be ar- + ranged that these are automatically written to the appropriate direc- + tory without any rewriting of the packages' code. Second is that the + files are often read in again on subsequent runs of *latex, and it is + necessary that the program knows where to find the files. + + A complication is that the TeXLive implementation does not allow for + separate aux and output directories. Latexmk deals with this by being + able to emulating a separate aux directory: In this method it invokes + *latex with just an -output-directory option, with the directory set + + + + 7 January 2023 27 + + + + + +LATEXMK(1) General Commands Manual LATEXMK(1) + + + not to the desired output directory, but to the aux directory. After + running *latex, it moves the relevant final output file(s) to the in- + tended output directory. Emulation can be turned on by setting the + configuration variable $emulate_aux to one in a configuration file or + by using latexmk's -emulate-aux-dir option. The emulation method works + equally well if MiKTeX is used. + + Latexmk also turns emulation on if it is found to be needed, as fol- + lows. Suppose emulation is initially off, but the aux and output di- + rectories are different. Then latexmk invokes *latex with an -aux-di- + rectory option and after the run finds that it hasn't been obeyed, no- + tably because the .log file is in the output directory rather than the + aux directory. Latexmk then sets emulation on, and retries. Conceiv- + ably, it could move all the appropriate generated files from the output + directory to the aux directory; but there is such a large variety of + possibilities for these files that this is hard to identify all of them + reliably except for simple cases. + + Note that the emulation issue only arises when the user has arranged + for the the aux and output directories to be different. When instead + they are equal, e.g., because the user only set the $out_dir variable, + then latexmk invokes *latex with only an -output-directory option, + which works as intended with both TeXLive and MiKTeX. + + In addition, latexmk arranges the invocations of any auxiliary programs + like bibtex and makeindex so that they will read and write the relevant + files from and to the aux directory. Programs like dvips, dvipdf, + ps2pdf, and xdvipdfmx are invoked so that they read from the appropri- + ate places and write their output to the output directory. + + Files considered as final output files, i.e., those that belong in the + output directory rather than the aux directory: These have the exten- + sions .dvi, .ps., .pdf, .synctex, and .synctex.gz. A special case, be- + cause of compatibility issues, is of .fls files: See below. + + Note that xelatex when invoked with its -no-pdf option, as latexmk + does, generates an .xdv file, which would appear to have the same sta- + tus as a .dvi file generated by latex. Nevertheless, latexmk treats + .xdv as an intermediate file that is found in the aux directory. This + is to match MiKTeX's treatment of the -aux-directory option. As fur- + ther justification, one can say that under modern conditions an .xdv + file is (almost) always an intermediate file. Historically, the situa- + tion with .dvi files from latex was different, and currently dvi pre- + viewers do exist. + + + Variables and options for directories: The variables for setting the + aux and output directories are $aux_dir and $out_dir, with correspond- + ing command line options -auxdir (or -aux-directory) and -outdir (or + -output-directory). When a value for these is blank (which is the de- + fault value), it implies the use of a default: For the aux directory, + the default is to set it equal to the output directory. For the output + directory, the default is to be the current directory. + + + + + 7 January 2023 28 + + + + + +LATEXMK(1) General Commands Manual LATEXMK(1) + + + For the turning on and off of the emulation mode, there is the configu- + ration variable $emulate_aux and the options -emulate-aux-dir, -emu- + late-aux-dir-, -noemulate-aux-dir. + + + Interaction with -cd option: When the -cd option is used (or the equiv- + alent setting of $do_cd variable), then latexmk changes the working di- + rectory to the document directory before invoking *latex. If the aux + and/or output directories are given by relative paths, e.g., by -out- + dir=output for a directory named "output", then the directories are + relative to the document directory, rather than relative to the working + directory that was in effect when latexmk was invoked. This matches the + behavior of *latex as invoked with the provided command line directory + argument(s) after the change of working directory to the document di- + rectory. + + Automatic creation of aux and output directories: Unlike *latex, if la- + texmk finds the requested directory/ies don't exist, it creates + it/them, thereby avoiding errors when *latex is invoked. + + If the document uses the \include macro to read a .tex file from a sub- + directory, *latex will attempt to write an extra aux file to the corre- + sponding subdirectory of the aux directory. If the subdirectory + doesn't exist, then *latex will complain that it can't write the aux + file. After the run of *latex, latexmk detects this situation, creates + the necessary directory, and reruns *latex with the error situation + corrected. + + Choice of aux and output directories: Often the aux and output directo- + ries are given as subdirectories of the document directory, e.g., by + -outdir=output. But it is possible to provide, for example, an absolute + path or a path relative to a parent directory, e.g., "/tmp/foo" or + "../output". Be aware that in general this can cause problems, notably + with makeindex or bibtex. This is because modern versions of these + programs, by default, will refuse to work when they find that they are + asked to write to a file in a directory that appears not to be the cur- + rent working directory or one of its subdirectories. This is part of + security measures by the whole TeX system that try to prevent malicious + or errant TeX documents from incorrectly messing with a user's files. + + By default, latexmk evades this issue: Before running bibtex and make- + index, latexmk changes working directory to the aux directory, with ap- + propriate settings of search paths. The use or non-use of this trick + is governed by the variables $bibtex_fudge and $makeindex_fudge. Un- + fortunately, the trick sometimes makes bibtex and makeindex unable to + find files. + + If necessary the trick can be turned off. But this is incompatible with + an aux directory like, "/tmp/foo" of "../output"). If you really have + to deal with this situation, and only if you have to deal with it, then + you need to disable the security measures (and assume any risks). One + way of doing this is to temporarily set an operating system environment + variable openout_any to "a" (as in "all"), to override the default + "paranoid" setting. + + + + 7 January 2023 29 + + + + + +LATEXMK(1) General Commands Manual LATEXMK(1) + + + Certain names of aux and output directories not allowed on Microsoft + Windows: It is natural to want to use the name "aux" for the aux direc- + tory, e.g., by using the option -auxdir=aux. But on Microsoft operat- + ing systems "aux" is one of the names that is not allowed for a file or + directory.

Almost users will not have - to worry about these settings, and can ignore the following ex- - planation. + $fls_uses_out_dir [0] + This variable determines whether or not the .fls file should be + in the output directory instead of the natural directory, which + is the aux directory. If the variable is nonzero, the .fls file + is to be in the output directory. See the section AUXILIARY AND + OUTPUT DIRECTORIES for more details about these directories. + The rationale for the existence of the variable + $fls_uses_aux_dir is explained there. - In almost all situations, latexmk does not need to use the time - stamps of the files it works with. However, there are a couple - of situations when it needs to know whether a certain file was - created in the current run of a program (e.g., *latex) or is a - leftover file from a previous run. It does this by comparing the - modification time of the file with the system time just before - the program was started. If the modification time is earlier - than when the program was started, the file is a leftover file, - which latexmk treats as if it were not created. If the filetime - is at least the program start time, then it can be assumed that - the file was created in the current run. + In all cases, if latexmk finds that an .fls file has been gener- + ated in the opposite directory to the one specified by + $fls_uses_out_dir, it copies the file to the other directory + (aux or output directory as appropriate). The file is copied + rather than simply moved, to avoid potential clashes with other + software that assumes the .fls file is generated in the direc- + tory it was written to by *latex. Thus the effect an incorrect + setting of $fls_uses_out_dir is only to cause a superfluous copy + of the .fls file to be generated. - Unfortunately, this test can fail if the file is on a remote - system, since its system time is not necessarily synchronized - with that of the local system; the timestamps on the remote - files are set by the remote system, not the local system. Gen- - erally, modern operating systems regularly synchronize their - time with a server, so the non-synchronization is mostly small - (a second or so, or a few seconds). But even a small difference - can mess up latexmk's test. - Latexmk measures the time difference between the time on the two - systems and compensates for this. But the measurement (in a - system-independent way) is only accurate to a second or two. So - latexmk allows for a threshold on the difference between file - and system time before it concludes that a file is a leftover - file from a previous run. The configuration variable $file- - time_causality_theshhold, which in units of seconds, specifies - this threshold. Luckily high precision is not needed. The pre- - vious run is normally the previous run in a human run-edit-run - cycle, and is at least many seconds back. A few seconds is - therefore appropriate for the threshold, $filetime_causal- - ity_theshhold; it should be non-negative always, and should be - bigger than 2 if a remote filesystem or network share is used. + $force_mode [0] + If nonzero, continue processing past minor latex errors includ- + ing unrecognized cross references.
