mailing-list for TeXmacs Users

[David Allouche <address@hidden>]

When you design a new TeXmacs stylesheet, and you distribute a document which 
uses this stylesheet, you want TeXmacs to find it without requiring your 
"users" to put your stylesheet in their personal ~/.TeXmacs/styles directory. 
Most of the time, the custom stylesheet will be located in the same directory 
as the document using it.

Currently, TeXmacs will look for stylesheets in the directories specified by 
the TEXMACS_STYLE_PATH environment variable, which defaults to 
".:$HOME/.TeXmacs/styles:$TEXMACS_PATH/styles". But here, "." refers to the 
directory where TeXmacs was started.

In most modern desktop setups, "." will always be $HOME since TeXmacs will be 
started from a laucher bar or an application menu. So TeXmacs will NOT find 
the custom stylesheet.

Attached is a somewhat kludgy patch to make stylesheets located in the 
directory of the document take precedence over any stylesheet found by 
searching TEXMACS_STYLE_PATH. This solution was inspired by the way linked 
images are found while typesetting the <postscript> element.

I think there would be two more elegant ways to do it:

  -- Change the working directory to the directory where the current document 
is located. For consistency, this should be done every time a TeXmacs window 
gets the focus and every time the buffer associated with the currently 
focused window is changed. Unamed documents could be associated with the 
directory where TeXmacs was started. This behavior is inspired by Emacs.

  -- Define an new environment variable that holds name of the directory 
where the current document is located, one could name it 
TEXMACS_DOCUMENT_PATH. The value of this variable should be updated in the 
same way as the working directory in the previous solution. This would allow 
the best control from the TEXMACS_*_PATH environment variables.

Since implementing one of these two solutions would require some discussion, 
I have sticked to the simplest solution I could find.

If anyone here have some opinion on this question, please tell me.

If anyone is getting really pissed off of me flooding his/her mailbox, please 
tell me, too ;-)
