Hi,
I want to create a macro that writes files in a sub directory. If the directory is already created, things work fine. However, if the directory is not there, tex complains
! I can't write on file ....
Please type another output file name:
Is there a way I can ask tex to create a directory if one does not exist?
Not with TeX, but you can use \write18 or \installprogram to run a system command.
Can I ask TeX to check if a directory exists or is writable. I want it to give an informative message if the directory does not exist.
Or is there a way to check if a file is writable, so that I can do
\doiffilewritable{dir/tempfile}{\donothing}{\message{Warning}{Please create directory 'dir' \endinput}
for a while there has been a way to ask for file characteristics (x-dir-01 can be used to generate a clickable listing and x-dir-05 for indentifying files) permissions were not part of that but easy to add, i'm generating you a beta that has permissions added \usemodule[x][dir-05] \getfilestate{context.tex} \doifinstringelse{w}{\getvariable{filestate}{permissions}} {writable} {not writable} \end ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
