[Texmacs-dev] Major changes in plug-ins, MacOS support for giac, sage and texgraph

[Joris van der Hoeven]

Dear all,

I made some intrusive changes in the plug-in support,
which may cause some plug-ins to disfunction.
Please test whether everything still works fine
(or at least not worse than before), for the SVN version.

For MacOS users of giac, sage and texgraph,
I made some changes so that the software is automatically found
if you installed the standard package or dmg for MacOS.

In the case of texgraph, I had to add support for the .sh extension
for the script which launches TeXgraph.  That meant a few changes
to tm_texgraph and init-texgraph.scm :

        [...]
        if [ "$OSTYPE" = "cygwin" ] ; then EXT='.bat'; else EXT=''; fi
        shext=`command -v CmdTeXgraph.sh`
        if [ "$shext" != "" ] ; then EXT='.sh'; fi
        CmdTeXgraph$EXT $EXPT $TEMP_FILE 2> tmp_log
        [...]

  [...]
  (:require (and (url-exists-in-path? "latex")
                 (or (url-exists-in-path? "CmdTeXgraph")
                     (url-exists-in-path? "CmdTeXgraph.sh"))))
  [...]

We are working on a similarly improved detection scheme under Windows.

Best wishes, --Joris
