From 21dd835f9d3199e5aa4c0570129b86214152f198 Mon Sep 17 00:00:00 2001 From: Enrico Forestieri Date: Sun, 6 Feb 2011 23:45:03 +0000 Subject: [PATCH] Don't rely on external utilities and use python modules for creating a LyX archive. A zip archive is created on Windows and a gzip compressed tar archive on *nix, as those are the de facto platform standards. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@37525 a592a061-630c-0410-9148-cb99ea01b6c8 --- lib/configure.py | 33 ++++++------------- lib/scripts/lyxpak.py | 74 +++++++++++++++++++------------------------ 2 files changed, 42 insertions(+), 65 deletions(-) diff --git a/lib/configure.py b/lib/configure.py index 4bf80fb05a..9fd21c819f 100644 --- a/lib/configure.py +++ b/lib/configure.py @@ -868,29 +868,16 @@ def checkConverterEntries(): checkProg('a Noteedit -> LilyPond converter', ['noteedit --export-lilypond $$i'], rc_entry = [ r'\converter noteedit lilypond "%%" ""', '']) # - # currently (as of 2/5/11), lyxpak outputs a tar archive if tar is found, - # and a zip archive if tar is not found but zip is. if tar is found, then - # it looks for gzip and bzip2, in that order, and compresses the archive - # using the one it finds. - # so, we mimic this search, and configure the appropriate version. - path, prog = checkProg('the LyX packing script', ['tar', 'zip']) - if prog: - cmd = r'\converter lyx %s "python -tt $$s/scripts/lyxpak.py $$r/$$i" ""' - if prog == "zip": - addToRC(r'\Format lyxzip zip "LyX Archive (zip)" "" "" "" "document"') - addToRC(cmd % "lyxzip") - elif prog == "tar": - path, prog = checkProg('gzip or bzip2', ['gzip', 'bzip2']) - if prog == "gzip": - addToRC(r'\Format lyxgz gz "LyX Archive (tar.gz)" "" "" "" "document"') - outfmt = "lyxgz" - elif prog == "bzip2": - addToRC(r'\Format lyxbz2 bz2 "LyX Archive (tar.bz2)" "" "" "" "document"') - outfmt = "lyxbz2" - else: - addToRC(r'\Format lyxtar tar "LyX Archive (tar)" "" "" "" "document"') - outfmt = "lyxtar" - addToRC(cmd % outfmt) + # Currently, lyxpak outputs a gzip compressed tar archive on *nix + # and a zip archive on Windows. + # So, we configure the appropriate version according to the platform. + cmd = r'\converter lyx %s "python -tt $$s/scripts/lyxpak.py $$r/$$i" ""' + if os.name == 'nt': + addToRC(r'\Format lyxzip zip "LyX Archive (zip)" "" "" "" "document"') + addToRC(cmd % "lyxzip") + else: + addToRC(r'\Format lyxgz gz "LyX Archive (tar.gz)" "" "" "" "document"') + addToRC(cmd % "lyxgz") # # FIXME: no rc_entry? comment it out diff --git a/lib/scripts/lyxpak.py b/lib/scripts/lyxpak.py index 458d4fbac6..76c4f70fe3 100755 --- a/lib/scripts/lyxpak.py +++ b/lib/scripts/lyxpak.py @@ -10,18 +10,23 @@ # Full author contact details are available in file CREDITS # This script creates a tar or zip archive with a lyx file and all included -# files (graphics and so on).
