Bugs item #377, was opened at 2005-07-02 21:43 You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=493&aid=377&group_id=106 Category: Image inclusion Group: None Status: Open Resolution: None Priority: 5 Submitted By: Georg Baum (baum) Assigned to: Martin Schröder (oneiros) Summary: unqoute image filenames not only on windows Initial Comment: The file pdftex-1.30.0-rc1/src/texk/web2c/pdftexdir/writeimg.c contains in the function readfile() a code block to unqoute file names which is inside #ifdef WIN32 ... #endif. This code should be enabled on all platforms (or at least on linux), since quoted filenames (which are necessary if the name contains spaces) do not only work well on linux. Thanks, Georg ---------------------------------------------------------------------- Comment By: Heiko Oberdiek (oberdiek) Date: 2005-07-04 16:07 Message: Logged In: YES user_id=1276 Hello, I must disagree, "the same behaviour on all platforms" can not mean to add the limitations of all platforms. Now you want the limitation of windows that quotes cannot be used apply on the other systems? There are operating systems that deal with 8+3 file names only. Do you want to forbid long file names, for example? Thus we are loosing both quotes and spaces. Spaces still cannot be used in general. Other TeX engines does not know about quoting. There is no secure way to know, whether quoting is working. Thus code that is intended for different systems must avoid spaces. And the current quoting scheme does not solve the problem at all, it moves the problem from spaces to quotes, spaces can still not be used and quotes are now made unavailable. Also the quoting scheme does not allow quoting of the quotes themselves. A solution would allow *all* characters. The solution should be able to deal with utf-8 or even ucs-2/4 encoded file names. That is already given by the syntax of \pdfximage. Thus new primitives \pdfinput, \pdfopenin, \pdfopenout with <general text> would allow any file name and a macro code can test, whether this feature is available by testing the command names.

I do think however that the behaviour on all platforms should be the same if it is at all possible. Right now, filenames with quotes work on linux and not on windows, and quoted filenames with spaces work on windows but not on linux. Thanks for the hint to pdfximage, I did not know about that (coming from standard LaTeX and always using \includegraphics} Georg ---------------------------------------------------------------------- Comment By: Heiko Oberdiek (oberdiek) Date: 2005-07-04 13:13 Message: Logged In: YES user_id=1276 Hello, it is a very bad idea, quotes are perfectly legal in linux and other operating systems. Also image inclusion is done by \pdfximage that uses <general text>, by <general text>, text surrounded by curly braces (catcode 1 and 2) *all* possible file names can be given including quotes and spaces. We need rather new primitives for \input, \openin, and \openout to provide the file names as <general text>. The all file names can be given without the need of quoting at all. See also the discussion about \pdfinput in the ntg-pdftex mailing list.
