Hi Bertrand:
The Mathics project you reference from the viewpoint of a quick look at
the documentation of the website is very interesting and definitely has
some potential for a TeXmacs plugin. This project has a way to go to
reach the level of development and support of say Maxima as a computer
algebra (symbolic math) system. The best part of this project is that it
is based on Python which promises some interesting and powerful
possibilities.
The TeXmacs Python plugin has worked well for me even when loading and
using modules that should it seems should reveal obvious defects in the
plugin if there are any. I have not found any so far. I have used it
with SciPy, NumPy, Scientific Python, Oct2Py, matplotlib, etc. In order
to use Mathics via a TeXmacs plugin the so-called console version of the
executable (mathics) command will almost certainly have to be used. I
recommend that you look to see first if this "executable" is merely a
shell or Python script file. If so it may be possible to merely adapt
the existing TeXmacs Python plugin for Mathics. You will have to see how
this file gets Mathics started. If it is merely a loaded module, then it
may be simply a matter of starting Mathics from the existing TeXmacs
Python plugin command line prompt -- Python].
The TeXmacs Python plugin is itself essentially a Python script that
waits for Python commands to be entered, which are parsed and
interpreted as input, and then the Python output is parsed and tidied up
for display as TeXmacs output. If Mathics turns out to be merely loaded
Python module(s) with associated namespaces, then I see no reason why
Mathics should not run using the Python plugin. I have used it with the
Oct2Py module which is a Python interface to Octave and this works
without any detectable problems.
However, keep in mind that you will not get the fancy rendering of
mathematics symbols that Mathics generates using its own built-in server
by way of a browser with MathJax support. The Maxima plugin somehow
converts its console output to equivalent math symbols like those
generated by LaTeX. I am not sure how you would do that with Mathics
using the Python plugin. You might look at the Input and Output section
of the Mathics documentation for the TeXForm function. This returns
Mathics expressions using LaTeX-like syntax.
Good luck.

Hello,
I recently discovered the project Mathics <http://www.mathics.org/>
of Jan Pöschko, which could be interesting as an open-source
substitute of mathematica.
Do you think it could be interesting/possible to develop a Texmacs
plugin for this application ?
best,
bertrand
