From 72230bb98cd8270d2aa9658999f8a5b24bbe996e Mon Sep 17 00:00:00 2001 From: Enrico Forestieri Date: Wed, 1 Jun 2011 22:22:58 +0000 Subject: [PATCH] On Windows, improve detection of the TeX engine by avoiding spaces in filenames passed to latex (through the short form of the path) and also by taking into account that a short form may not always be available. Such detection may still fail if the file system does not support short names and the TeX engine doesn't allow spaces in filenames, but this is a highly improbable condition, hopefully. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/branches/BRANCH_2_0_X@38921 a592a061-630c-0410-9148-cb99ea01b6c8 --- lib/configure.py | 14 ++++++++++++-- status.20x | 3 +++ 2 files changed, 15 insertions(+), 2 deletions(-) diff --git a/lib/configure.py b/lib/configure.py index b376d5029d..c14bf0b04a 100644 --- a/lib/configure.py +++ b/lib/configure.py @@ -102,7 +102,15 @@ def checkTeXPaths(): from tempfile import mkstemp fd, tmpfname = mkstemp(suffix='.ltx') if os.name == 'nt': - inpname = tmpfname.replace('\\', '/') + from ctypes import windll, create_unicode_buffer + GetShortPathName = windll.kernel32.GetShortPathNameW + longname = unicode(tmpfname) + shortlen = GetShortPathName(longname, 0, 0) + shortname = create_unicode_buffer(shortlen) + if GetShortPathName(longname, shortname, shortlen): + inpname = shortname.value.replace('\\', '/') + else: + inpname = tmpfname.replace('\\', '/') else: inpname = cmdOutput('cygpath -m ' + tmpfname) logname = os.path.basename(inpname.replace('.ltx', '.log')) @@ -110,6 +118,8 @@ def checkTeXPaths(): os.write(fd, r'\relax') os.close(fd) latex_out = cmdOutput(r'latex "\nonstopmode\input{%s}"' % inpname) + if 'Error' in latex_out: + latex_out = cmdOutput(r'latex "\nonstopmode\input{\"%s\"}"' % inpname) if 'Error' in latex_out: logger.warning("configure: TeX engine needs posix-style paths in latex files") windows_style_tex_paths = 'false' @@ -1293,7 +1303,7 @@ def checkTeXAllowSpaces(): msg = "Checking whether TeX allows spaces in file names...
