List of main changes in latexmk From v. 3.04 to v. 3.07 Pdf files can be made by any of three methods: pdflatex, from dvi or from postscript. Extra command-line options -- see documentation Improved configuration options -- see documentation Bug fixes, etc Improved detection of dependencies If latexmk exits because of an error with latex, bibtex or makeindex, then it gives a non-zero exit code. Under MS-Windows allow wildcards in filenames. From v. 3.07 to v. 4.01 Allow dvips, etc to put files in temporary location then move to final location. This enables the problem to be avoided that some viewers look for changes in a file and read a new file before the writing of it is complete. Ensure that an error in exectuing an rcfile results in an error message visible to the user. OS-specific initialization code now includes section for Mac OS-X. Make code safe, as far as possible, for filenames containing spaces. Change method of detecting out-of-date-ness, etc, to examine all files for changes. Keep a database (in a file with extension fdb_latexmk) of the previous state of the files. The aux.bak and idx.bak files are no longer used. The primary method of detecting change is from the md5 checksum of a file. This deals automatically with the vast majority of cases where there is circular dependence of files, without needing special coding in latexmk to know which input files to a LaTeX run are generated from a previous run. Hence make a much more systematic and general method for treating dependencies. Substituteable place holders allowed in command specifications, to allow very general specification of commands (including multiple commands, pipelines etc). Extra option --dependents to list dependent files. Support for multibib.sty, multind.sty, etc. Support for index.sty as well as makeidx.sty. Allow .latexmkrc as file name in project directory (as opposed to latexmkrc). Command-line option -e to allow execution of initialization code from command-line invocation of latexmk. Routines add_cus_dep, remove_cus_dep and show_cus_dep for manipulating custom-dependency list. Ability to specify lines to be ignored in computing md5 checksum of a file of a particular extension. (An example would be a comment line in an encapsulated postscript file that contains the date and time it was created. Such lines may change without having any consequence on the use of the file.) Miscellaneous bug fixes, etc. Improvements in parsing of log file From v. 4.01 to v. 4.05 Miscellaneous bug fixes Fix bug that -ps -pdfps runs ps2pdf before dvips Deal with quoted filenames in log file Correct problem with invocation of MSWin start command -c and -C now also delete fdb_latex file For home directory (where user's .latexmkrc is located, when $ENV{'HOME'} does not exist, use $ENV{USERPROFILE} (suitable for MS-Win). Correct treatment of -e option Fix possibility that unwrapping of lines in log_file is done incorrectly Correct parsing of log file Improve diagnostics of reasons for rerun of external program. Fix problems when using both latex and pdflatex Configurable extensions for finding cusdep Change to a nicer #! line Safer use of % in placeholders in commands From v. 4.05 to v. 4.07 In preview-continuous mode, arrange that ctrl/C used to stop the processing loop does not automatically kill a script used to call latexmk Better handling of situation when a run of (pdf)latex does not produce a dvi or pdf file, or when the opposite type of output is produced than expected (e.g., pdf instead of dvi by latex) Deal better with case that file is written and read by (pdf)latex during a run From v. 4.07 to v. 4.10 Binmode for log file under MSWin to avoid problem with ctrl/Z written by Miktex 2.7 giving spurious end-of-file. Deal with issues in depedency structure caused by epstopdf, which automatically creates pdf files from eps files during run of pdflatex. Correct problem with determining use of custom dependencies, when file-not found-report has extensionless filename, but corresponding .tex file exists. Preview-continuous mode now doesn't bomb out if there are errors during first run of (pdf)latex. (Previously that caused the previewer not to run even if viewed file exists.) From v. 4.10 to v. 4.11 Corrects a long-standing bug that when the main file uses bibtex, and uses \include for subdocuments, changes in bibliography citations did not always trigger a rerun of bibtex. Fixed a problem that latexmk did not detect changed aux files etc on a small document when the run of (pdf)latex was within the 1-second granularity of filetimes. Improved start-up times on some large documents by avoiding unnecessary recalculations of md5 checksums. Deals better with eps-to-pdf conversions reported by epstopdf package. -silent option now causes suppression of certain messages about non-existent files When view files are make via a temporary file (not-yet-documented feature), delete old view file before moving the temporary file. (To avoid reported bug in kpdf and okular.) Corrects a problem that with an error introduced at v. 4.08 that on finding an error in processing one file latexmk exits rather than continuing processing other requested files. The exit code returned by latexmk was also incorrect in this situation From v. 4.11 to v. 4.12 Added an option not to run bibtex (to deal with situations where a bbl file is available but not the bib file from which it was made). Corrected misprints in documentation. From v. 4.12 to v. 4.13 Corrected clean_up so aux file is deleted. Default for running bibtex: Only when .bib file exists. Correction insertion of bbl into list of generated extensions. From v. 4.13 to v. 4.13a Corrected a problem that clean-up option (-C) failed to delete certain generated files. From v. 4.13a to v. 4.15 Change defaults on $latex_silent_switch and $pdflatex_silent_switch to make them always TeXLive compatible. To avoid problems with apparent source files that are incorrectly determined from the log file: (a) Make sure md5 calc doesn't bomb out on directory. (b) In parsing log file: if apparent dependent file is directory, remove it from list of dependent files. Better diagnostics at end of run with multiple files: list applications of latex and pdflatex that failed. Fixed problem that with -pvc when (pdf)latex failed, latexmk kept doing dvips, dvipdf, etc. From v. 4.15 to v. 4.15b Changed default location of system rc files for cygwin to include both Unix-like and MSWindows paths. Changed use of Digest module to use of Digest::MD5 module, to give compatibility with the limited installation of perl shipped with TeX Live. From v. 4.15b to v. 4.15c Solved problem that occasionally latexmk failed to detect a dependent file when it analyzed a .log file. (It incorrectly treated some lines of length 79 as being wrapped.) From v. 4.15b to v. 4.16 Solved another problem with misparsed log files. Some versions of pdflatex fail to preceed some warning messages by a new line. Thus these warning messages sometimes appear to be part of a filename. Updated documentation to mention previously undocumented feature about the use of temporary files in making ps and pdf files. From v. 4.16 to v. 4.16a Sanity check on $sleep_time. (Negative times and times between 0 and 1 are replaced by 1.) Corrected problem under preview-continuous mode that some previewers would not see the changed file on an NFS file system. From v. 4.16a to v. 4.17 Deal with bug about misparsing log file with non-space-containing filename that is followed by a space and a message on same line. Previously, the filename would not be detected as a dependent. With $force_mode on, do a better job of completing processing. Remove long-unused options -F and -F- From v. 4.17 to v. 4.18 Only produce "Removing no-longer-needed dependent" messages when diagnostics are on. In analysis of log file, add test for natbib's citation-undefined warning. Correct misprint in documentation. From v. 4.18 to v. 4.20 Fix problem that when bibtex finds no citations, this is treated by bibtex as an error. Previously latexmk respected this and did not continue processing. Now if the only bibtex error is the finding of no citations, then latexmk now treats it as only a warning and continues processing (by latex/pdflatex) as appropriate. Get .bst file in source file list for bibtex. (So an update to the bst file provokes a rerun of the relevant programs.) Allow clean-up to delete destination files of custom-dependencies Configuration variable $cleanup_includes_cusdep_generated to configure whether this is done. (Default is off, for backward compatibility.) Remove use of --width option on $pscmd on linux. It's no longer needed. Remove double quotes (if any) surrounding output filename read from .log file, to avoid wrong diagnostic message. Allow a more general pattern for files to clean up (when the -c, or -C option is used). For details, see the explanation of the $clean_ext variable in the latexmk documentation. Options to set commands used for latex and pdflatex, as in -latex=special_latex_replacement_command -pdflatex=special_pdflatex_replacement_command (This is not yet documented.) From v. 4.20 to v. 4.21 Fix some problems with parsing quoted filenames in log file. These prevented latexmk working correctly with latest version of asymptote.sty. Corrected potential bug in locating graphics files. From v. 4.21 to v. 4.22 Support use of biber (with the biblatex package) for generating bibliographies, with automatic selection of bibtex or biber. From v. 4.22 to v. 4.22b Compatibility with biber 0.7.2. (Latexmk failed to detect .bib files used by biber 0.7.2.) From v. 4.22b to v. 4.22c Biber support is now compatible with MikTeX. From v. 4.22c to v. 4.22d Fix compatibility problem MiKTeX v. 2.8, that latexmk didn't always detect use of makeindex. From v. 4.22d to v. 4.22e Fix incorrect error handling in reading initialization files. (Sometimes an error was incorrectly detected, after which latexmk stopped.) From v. 4.22e to v. 4.23 Deal with problem that if maximum number of runs of (pdf)latex is exceeded, -pvc mode infinitely repeats (pdf)latex Fix problem that changes in generated files during run of (pdf)latex may not be detected if the run is shorter than the granularity of file times. Corrections of comments and messages. Documentation improvement. Correctly parse blg files of biber 0.8 Correct handling of errors given by rc files Enhancements for convenient use of latexmk with Makefiles (options -deps, -deps-out, -use-make) -recorder option for improved detection of input and output files. From v. 4.23 to v. 4.23a Correct bug in detection of source files listed in .fls file From v. 4.23a to v. 4.24 When running biber, find locations of source files when they aren't in the current directory (by use of kpsewhich). This was previously done for bibtex but not biber. From v. 4.24 to v. 4.25 Fix to evade apparent cygwin bug that prevented system rc-file from being read. Diagnostic for unreadable rc-file. Add deps output file to target part of dependency information From v. 4.25 to v. 4.26 Make compatible with biber 0.9.4. Fix some bugs in error reporting. From v. 4.26 to v. 4.27a Deal with problem that making of ps or pdf file via a temporary file fails if the command making it has no %D placeholder Add png to list of graphics extensions for pdflatex Add -norc option that prevents auto reading of rc files. Options -aux-directory -output-directory like those of (pdf)latex, to set the output directories of (pdf)latex. (-aux-directory is MiKTeX only). Corresponding configuration variables, and placeholders for command specification. From v. 4.27a to 4.28 Correct handling of situations where some file(s) needed by bibtex (or biber) don't exist. Previously latexmk incorrectly stopped with an error message instead of continuing. From v. 4.28 to 4.28a Correct duplicate making of view file From v. 4.28a to 4.28c When biber doesn't find the bib file, latexmk treats this as a warning rather than a fatal error, so further processing can continue normally. Latexmk now parses correctly error messages from biber v. 0.9.7. From v. 4.28c to 4.29a Latexmk now works with the feynmp package and mpost, provided a suitable custom dependency is defined. (See the example latexmkrc fragment mpost_latexmkrc in the example_rcfiles directory in the latexmk distribution.) If output directory is set, arrange that dvips can find files there. In searching for cus-deps that can make a missing file, look in $out_dir. Solves problem that sometimes dvips and dvipdf weren't run when they should have been. (The problem only arose with certain changes in eps files being made within a minute of the previous run.) From v. 4.29a to 4.30a Fix use of bibtex so that it works correctly when $aux_dir and/or $out_dir are set. Use OS-dependent search path separator when when manipulating TEXINPUTS, etc. Then use of -output-directory and -aux-directory options should work on MSWin systems. Documentation of $search_path_separator variable. From v. 4.30a to 4.31 Add -M -MP and -MF options, like gcc. Recorder option is now on by default. Add options reproducing most options of (pdf)latex (list from both TeXLive and MikTeX versions). Options NOT implemented by latexmk at all: -ini and -initialize since they refer to operations not supported by latexmk -includedirectory=dir its support needs extra code in latexmk, not currently written Options differently processed by latexmk: -help -version -quiet Options that are passed to (pdf)latex but that also have special processing by latexmk -aux-directory=dir -output-directory=dir -recorder Add -latexoption=... option to latexmk Add -xelatex option for use of xelatex Change OS-X default for pdf previewer command to open Command specification string can start with "include routine" to invoke a Perl subroutine instead of an external cmd. Viewers are detached by default. (The start keyword is now normally superfluous in command specifications.) Keyword nostart added in command specification. Add configuration variables $compiling_cmd, $success_cmd, $failure_cmd. These specify external commands (if any) to be executed during latexmk's continuous preview mode at the following points: $compiling_cmd at the start of compilation, $success_cmd at the end of a successful compilation, and $failure_cmd at the end of an unsuccessful compilation. They can be used, for example, to show the progress of compilation by setting the titles of editor and/or previewer windows. If aux and/or output directories are specified but don't exist, make them. Remove excessive repetition of tests for changes of source files (improves performance of latexmk in some situations). Documentation improvements. Minor bug corrections. From v. 4.31 to 4.33a Improve operation under MSWindows: substitute "\" for "/" for directory separator in command lines, deal consistently with directory separator, which can be both "\" and "/". Correct some bugs that interfered with use of auxiliary directory and output directory for files generated by (pdf)latex, especially with MiKTeX. Fix problems caused because in the log and fls files MiKTeX writes absolute path for many filenames at and below current directory, and is inconsistent in its use of "/" vs. "\" as directory separator. Add $dvipdf_silent_switch configuration variable. Improve handling of errors in (pdf)latex; previously latexmk would give up processing in some situations continuing is correct. Documentation corrections/improvements. Reduce number of warnings in silent operation. Cure slowness of v. 4.33 under Cygwin. From v. 4.33a to 4.33b Documentation improvements. Improve text displayed by using -showextraoptions option. From v. 4.33b to 4.33c Correct infinite loop when maximum passes through latex/pdflatex are exceeded From v. 4.33c to 4.34 Correct non-optimality that if (pdf)latex reads a file only after it has been written in the same run, the file is not a true source file, but nevertheless latexmk treats it as a source file. Thus changes in the file sometimes caused latexmk to make unnecessary (but otherwise innocuous) extra runs of (pdflatex). From v. 4.34 to 4.35 Correct bug in parsing fls file from native MS-Windows LaTeX (e.g., MiKTeX) when latexmk is run under cygwin. (The names of some files used by latexmk incorrectly contained a CR character.) Correct bug that when the --gg option is used, the rule database from the old fdb file was used instead of being cleared. From v. 4.35 to 4.37 Correct failure that happens when name of current directory contains characters with special meaning in regular expression. -rules option now works with -pvc Add -lualatex option, like -xelatex. File specifications in $clean_ext and $clean_full_ext are allowed to contain wildcards. Warnings are given when rc file is a directory instead of a file. Correct bug that if revtex4-1.cls is used, footnotes are set to be in the bibliography, and latexmk's aux_dir or out_dir is set, then latexmk fails to run bibtex when needed, because the relevant bib file is not found. Other minor corrections and code improvements. Documentation updates and corrections. From v. 4.37 to 4.39 Automatic creation of necessary subdirectories of auxdir when needed for writing aux files. Add error diagnostics to if_source Allow $print_type = 'auto', and make this the default, so that when the -p option to latexmk is used to print the file, the default is to determine the type of file to be printed, rather than always requiring postscript. Fix the failures when dealing with directories whose names contained certain special characters in them (notably '[', ']' and space). [Technical issue: these characters had special meaning when previously interpreted as metacharacters in a glob operation.] This gives dependency on Perl's File::Glob module, which is a standard module in normal installations of Perl. When an output directory is a subdirectory of a directory, ensure that it is correctly created, if it has to be created. Previously, the creation of the output directory when it does not exist only worked for one level. This gives dependency on Perl's File::Path module with v. >= 2.08, which is a standard module in normal installations of Perl. In output of dependencies, include pathname of target file(s) in the rule. In -pvc mode, writing of deps file (caused by the -M and related options) is per make not per overall run. From v. 4.39 to 4.39 documentation update of 2 Dec 2013 Correct two errors in documentation and in the file COPYING. From v. 4.39 to 4.40 Fix failure to clean up correctly when root filename contains [, which is a glob metacharacter. From v. 4.40 to 4.41 -c also deletes $deps_file if it is used Quote jobname when needed. Change maintainer's preferred e-mail Attempt to improve handling of errors from (pdf)latex. Fix up for the making of -eps-converted-to.pdf Improve listing of warning lines from log file. Fix failure when using both -cd and -output-directory If user's home directory can't be determined, then don't read ~/.latexmkrc Introduce configuration variable $silence_logfile_warnings In setting $pscmd, allow for non-existent environment variable USER Correct subroutine Run for internal cmd w/o arguments Experimental: Add analysis hook for aux file. System initialization files: allow them to be named latexmkrc as well as LatexMk, for more consistency with user directory names. Keep both cases, to preserve backward compatibility. Change sign-on message. Bug report info with help. From v. 4.41 to 4.42 Fix bugs associated with the -cd option Add missfont.log and the generated synctex.gz to standard cleaned-up files From v. 4.42 to 4.43a Fix problem that source files are not correctly detected under MiKTeX when name of current working directory contains non-ASCII characters. On cleanup, synctex.gz files are deleted only by -C, not by -c. From v. 4.43a to 4.43c Correct normalization of filenames, so that initial "./" is always removed. This prevents custom dependencies being run twice on the same file. Documentation correction on use of @BIBINPUTS. Diagnostic correction. Example rc file for using texinfo (thanks to Vincent Bela\"iche). Additions to documentation concerning advanced configuration. From v. 4.43c to 4.44 Correct bug in use of %hash_calc_ignore_pattern (Previously it only had its documented effect when a targetted file hadn't changed in size.) Correct error handling when biber finds a malformed .bcf file. From v. 4.44 to 4.45 Fix problem of -C not always working correctly when compilation was with -pdf and clear was default. Fix bug in limiting number of passes when $max_repeat >= 10 Fix bug in finding id of viewer process id under OS-X From v. 4.45 to 4.46 Correct creation of output and aux directories to correctly handle relative paths when -cd is used. Minor documentation corrections. From v. 4.46 to 4.48 Correct documention: default value of $recorder is 1 Add routines rdb_list_source, rdb_set_source for manipulating dependency lists of a rule. Add these to the documentated interface, in addition to the already documented rdb_ensure_file, rdb_remove_files. Update webpages in documentation. From v. 4.48 to 4.52 Optimize number of calls to kpsewhich. This often gives a considerable savings of run time when a document includes many graphics files that are in a texmf tree. Fix bug that if an .aux file is deleted and latexmk is run, the wrong number of runs of (pdf)latex was made. Fix related problem that latexmk sometimes does too few runs of (pdf)latex because of the incorrect detection that a file is only read after being written. Implement direct support for xelatex and lualatex. Previously these programs were used by configuring the $pdflatex so that the desired program is run instead of pdflatex. There are now configuration variables $xelatex and $lualatex to specify the commands used, and extra command line options -pdfxe and -pdflua. In the case of xelatex, considerable improvement in run time is given for documents containing large graphics files. This is because compilation is made first to an xdv file instead of direct to a pdf file. Only when this file is finalized is a single conversion to a pdf file made. (This last step can be especially time-consuming for documents that bring in large graphics files.) Correct detection for missing graphics files with xelatex. Work around LuaTeX line-wrapping bug. Update documentation. Minor improvements in code and diagnostics.
