Merge lp:~matttbe/ubuntu/raring/latexmk/v4.35 into lp:ubuntu/raring/latexmk

[Matthieu Baerts]

Hello,

As you can see, Latexmk is available in Debian and Ubuntu repositories but it's an old version (4.24 - released more than one year ago).

A new version has been released less than two months ago and it's still not available in Debian repositories. It seems that the official maintainer doesn't answer to these bugs reports:
 * http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=668926 => [PATCH] latexmk: Helping to update to packaging format 3.0
 * http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=693126 => latexmk: New upstream release available + watch file

Is it possible to upload this new version to Ubuntu repositories because it will be needed by the new version of LaTeXila (and also because it fixes other bugs, please have a look at this debian/changelog file). Or should I first report this bug to another Debian dev? Or is it easier to upload this new version to Ubuntu repos first because Debian Testing migration has been frozen?
This new version has been uploaded to mentors.debian.net but I'm not sure that I'll receive an answer from the official Debian maintainer soon.

Thank you for your help,

Matt

PS: this new version can be easily tested by using this package: https://launchpad.net/~matttbe/+archive/experimental-debian-build/+sourcepub/2900053/+listing-archive-extra

[Andrew Starr-Bochicchio (andrewsomething)]

Looks good, but I did make a few tweaks to the changelog. I condensed it to one entry as the proposed Debian versions haven't actually entered the Debian archive. I also dropped the upstream changelog as it's really more verbose than we need for debian/changelog.

Thanks for your work!

* New upstream release. (LP: #1094164)
* Upstream ChangeLog:
  - 4.35 dated 11 November 2012.
    * Corrects bug that fls file is incorrectly parsed when using a
      combination of cygwin and a native MS-Windows TeX program.
    * Corrects bug that old dependency information was retained when using
      the --gg option.
  - 4.34 dated 1 October 2012.
    * Corrects non-optimality that latexmk may do extra runs of (pdf)latex
      when a file is read and written during a run of (pdf)latex, but the
      file is only read after being written.
  - 4.33c dated 19 August 2012.
    * Corrects infinite loop in error messages when the maximum number of
      passes through latex/pdflatex is exceeded.
  - 4.33b dated 12 August 2012.
    * Documentation improvements, including documentation of the many
      options for the (pdf)latex programs that are supported by latexmk.
  - 4.33a dated 8 August 2012.
    * Fix slowness of v. 4.33 under Cygwin.
  - 4.33 dated 6 August 2012.
    * 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.
  - 4.31 dated 30 March 2012.
    * Implement most options allowed by latex and pdflatex.
    * Add -M -MP and -MF options, like gcc.
    * Recorder option is now on by default.
    * 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.
  - 4.30a dated 9 December 2011.
    * 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 correctly on MSWin systems.
    * Documentation of $search_path_separator variable.
    * Correct some bugs in v. 4.30 that manifested themselves under MSWin
      especially with Cygwin.
  - 4.29a dated 7 December 2011.
    * 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.
  - 4.28c dated 1 December 2011.
    * 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.
  - 4.28a dated 28 November 2011.
    * 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.
    * Correct duplicate invocations of dvipdf, ps2pdf
  - 4.27a dated 10 October 2011.
    * 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.
  - 4.26 dated 9 August 2011.
    * Make compatible with biber 0.9.4.
    * Fix some bugs in error reporting.
  - 4.25 dated 7 July 2011.
    * 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.

+      * Use OS-dependent search path separator when when manipulating
+        TEXINPUTS, etc. Then use of -output-directory and -aux-directory

+    - 4.28c dated 1 December 2011.
+      * When biber doesn't find the bib file, latexmk treats this as a

+      * Latexmk now parses correctly error messages from biber v. 0.9.7. 
+    - 4.28a dated 28 November 2011.

+      * Correct duplicate invocations of dvipdf, ps2pdf 
+    - 4.27a dated 10 October 2011.

+# This is to allow the use of Sweave with latexmk, and in addition to
+#    make synctex work properly with it.  
+# SEE THE IMPORTANT NOTES below.
+#
+# Sweave (http://www.stat.uni-muenchen.de/~leisch/Sweave/) is a tool
+# that allows to embed the R code for complete data analyses in latex
+# documents.  The user edits a file with an extension like .Rnw, and
+# the .tex file is generated from this.
+#
+# Four problems are solved by the code below:
+# 1. Generate the .tex file automatically.
+# 2. Arrange not to re-run unmodified chunks of R code.  (A pure
+#    optimization.)
+# 3. Fix the execution environment for (pdf)latex.
+# 4. Deal with synctex: If the user wants to use synctex
+#    (www.tug.org/TUGboat/tb29-3/tb93laurens.pdf) to synchronize the
+#    pdf file with the source file, by default synctex does the
+#    synchronization with the generated .tex file, not the original 
+#    source file.  Postprocessing of the .synctex.gz file is necessary
+#    to fix this.
+#
+# The following version was worked out and  tested by a user (thanks
+# to Brian Beitzel) on MSWindows.  It will need at least one change to
+# work on UNIX-like operating systems (which include Linux and OS-X).
+
+# N.B. ===> IMPORTANT NOTES <===
+#
+# 1. The patchDVI package for R needs to be installed from R-Forge, as
+#    follows:
+#
+#  install.packages("patchDVI", repos="http://R-Forge.R-project.org")
+#
+# 2. In all Sweave (.Rnw) documents, the following lines must be included:
+#
+#         \usepackage{Sweave}
+#         \SweaveOpts{concordance=TRUE}
+
+
+# Fix the pdflatex command to run Sweave first, and to postprocess the
+#  .synctex.gz file:
+# !!!!! THIS IS THE VERSION FOR MS-WINDOWS, with && as a command
+# separator
+$pdflatex = "cmd /c "

+# This is to allow the use of Sweave with latexmk, and in addition to

+# SEE THE IMPORTANT NOTES below.
+#
+# Sweave (http://www.stat.uni-muenchen.de/~leisch/Sweave/) is a tool
+# that allows to embed the R code for complete data analyses in latex
+# documents.  The user edits a file with an extension like .Rnw, and
+# the .tex file is generated from this.
+#
+# Four problems are solved by the code below:
+# 1. Generate the .tex file automatically.
+# 2. Arrange not to re-run unmodified chunks of R code.  (A pure
+#    optimization.)
+# 3. Fix the execution environment for (pdf)latex.
+# 4. Deal with synctex: If the user wants to use synctex
+#    (www.tug.org/TUGboat/tb29-3/tb93laurens.pdf) to synchronize the
+#    pdf file with the source file, by default synctex does the
+#    synchronization with the generated .tex file, not the original 
+#    source file.  Postprocessing of the .synctex.gz file is necessary
+#    to fix this.
+#
+# The following version was worked out and  tested by a user (thanks
+# to Brian Beitzel) on MSWindows.  It will need at least one change to
+# work on UNIX-like operating systems (which include Linux and OS-X).
+
+# N.B. ===> IMPORTANT NOTES <===
+#
+# 1. The patchDVI package for R needs to be installed from R-Forge, as
+#    follows:
+#
+#  install.packages("patchDVI", repos="http://R-Forge.R-project.org")
+#
+# 2. In all Sweave (.Rnw) documents, the following lines must be included:
+#
+#         \usepackage{Sweave}
+#         \SweaveOpts{concordance=TRUE}
+
+
+# Fix the pdflatex command to run Sweave first, and to postprocess the

+    $success_cmd   = "xdotool search --name \\"%D\\" set_window --name \\"%D OK\\"";

 If you use pdflatex instead of latex, then you will probably prefer to
 convert your graphics files to pdf format, in which case you would
 replace the above code in an initialization file by
 
     add_cus_dep( 'fig', 'pdf, 0, 'fig2pdf' );

+\fBNote 1:\fR In the command lines given in the system commands in the
+above examples, double quotes have been inserted around the file names
+(implemented by '\"' in the Perl language).  They immunize the running
+of the program against special characters in filenames.  Very often
+these quotes are not necessary, i.e., they can be omitted.  But it is
+normally safer to keep them in.  Even though the rules for quoting
+vary between operating systems, command shells and individual pieces
+of software, the quotes in the above examples do not cause problems in
+the cases I have tested.
+
+\fBNote 2:\fR One case in which the quotes are important is when the
+files are in a subdirectory and your operating system is Microsoft
+Windows.  Then the separator character for directory components can be
+either a forward slash '/' or Microsoft's more usual backward slash
+'\\'.  Forward slashes are generated by latexmk, to maintain its
+sanity from software like MiKTeX that mixes both directory
+separators; but their correct use normally requires quoted filenames. 
+(See a log file from a run of MiKTeX (at least in v. 2.9) for an
+example of the use of both directory separators.)

 If you have some general custom dependencies defined in the system or
 user initialization file, you may find that for a particular project
 they are undesirable.  So you might want to delete the unneeded ones.
