Group: v1.40.0 Status: Closed Resolution: Wont Fix Priority: 5 Submitted By: Reinhard Kotucha (reinhard) Assigned to: Nobody (None) Summary: Filenames with multiple spaces are not recognized

Initial Comment: $ echo 'hello world\bye' > hello\ \ world.tex $ cat hello\ \ world.tex hello world\bye $ pdftex hello\ \ world.tex This is pdfTeX, Version 3.141592-1.40.3 (Web2C 7.5.6) entering extended mode ! I can't find file `"hello world.tex"'. <*> "hello world.tex" Please type another input file name: It seems that pdftex gets the correct name (with two spaces) but it is searching for something different. Regards, Reinhard ----------------------------------------------------------------------

Message: Logged In: YES user_id=421 I agree: This is simply an undocumented misfeature. Anybody who uses space in filenames in TeX does so at this own risk, and this should be documented. I don't think the time for fixing this is justified. ---------------------------------------------------------------------- Comment By: Nobody (None) Date: 2007-04-17 23:36 Message: Logged In: NO The command line is scanned by TeX. The catcodes for the filename are determined by the format. If you want TeX to be able to deal with multiple spaces, you can do so by doing \everyjob\expandafter{\the\everyjob \catcode`\ =10\relax} \catcode`\ =12 \dump% as the last thing when generating your format file. ---------------------------------------------------------------------- Comment By: Taco Hoekwater (taco) Date: 2007-04-17 23:20 Message: Logged In: YES user_id=1608 It will handle this properly: $ pdftex hello\ \space\ world.tex The problem (of course) is that the tokenizer will fold two (or more) tokens of \catcode 10 into a single one, so you have to prevent tex from seeing two of these in-a-row. It may actually be possible to fix the case where the file is given as a single argument on the commandline, but fixing the general case is unreasonably hard (e.g. \input commands used inside macros), I do not think would be worth the effort and therefore vote for documenting the current behaviour as a known limitation. ---------------------------------------------------------------------- You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=493&aid=776&group_id=106
