Hello me,

I just wrote a plugin for TeXgraph. This software makes it possible to create graphs which will be used inside LaTeX (you can find this really good software in French at http://texgraph.tuxfamily.org/index.html).
I followed the help files to create two files :
- tm_texgraph based on tm_pstricks by Nicolas Ratier
- init-texgraph.scm based on init-eukleides.scm by Joris van der Hoeven.
To use it, you have to extract texgraph.tar.gz in the "~/.TeXmacs/plugin" directory under linux and to install TeXgraph of course.
A new version of the TeXgraph plugin is attached.

As it is my first attempt to do something like this, it is not clean and seems buggy.
There are a few things I can't correct. For example, in the following TeXgraph session in TeXmacs, I can't remove the red <\errput> just below the graph.

With a little help by the developer of Texgraph, P. Fradin, I have succeeded in correcting this little problem and I added a test which let you know if you have done a syntax error and what kind of error has been done (missing bracket or coma...).

Everything works fine now and the whole thing is really worth trying. It is a really good complement to Eukleides, easy to use and efficient for plotting, 3D...

Last thing. In the session heading, I would like to know if it is possible to add :
1. a link to a documentation for TeXgraph commands which could be placed in the /plugins/texgraph folder
2. a folded environnement where I could place a few TeXgraph commands.

Let me know if you need more information or if there are things to correct.


Bye.
Bye.

# write texgraph-commands within the input line, use as many commands as necessary,

# output is the graph made via TeXgraphCmd, latex, and dvips -E mode.
