Hi Jean, Thanks a lot again, the proposed method works on the command line! I'll implement it in the actual preview-latex code.
By the way, if I remember correctly, filenames with multiple contiguous spaces are not supported by TeX, aren't they? Standard pdflatex just fails for such file names: ---------------------------------------------------------------------- [bash]$ cp ppp\ qqq.tex aaa\ \ bbb.tex [bash]$ pdflatex aaa\ \ bbb.tex This is pdfTeX, Version 3.14159265-2.6-1.40.19 (TeX Live 2018) (preloaded format=pdflatex) restricted \write18 enabled. entering extended mode ! I can't find file `"aaa bbb.tex"'. <*> "aaa bbb.tex" (Press Enter to retry, or Control-D to exit) Please type another input file name: ---------------------------------------------------------------------- So I suppose that it is not necessary for preview-latex to support such file names. >>>>> jfbu <j...@free.fr> writes: > In short, in presence of the /AUCTEXINPUT hack, the original space hack > simply ceases functioning because the space catcode is reset to "ignore" > too soon (at \everyjob) > How to fix this ? > With this new version of ini file > \ifx\pdfoutput\undefined\else\let\PREVIEWdump\dump\def\dump{% > \edef\next{{\pdfoutput=\the\pdfoutput\relax\the\everyjob}}% > \everyjob\next\catcode`\ 10 % > \catcode`/ 0 % > \def\AUCTEXINPUT##1{\catcode`/ 12\relax\catcode`\ > 9\relax\input{\detokenize{"##1"}}}% > \let\dump\PREVIEWdump\dump}\fi\input mylatex.ltx \relax% > Notice that when ##1 (i.e. the filename) will be grabbed) the / is of > catcode 0, so ##1 is tokenized accordingly.
