The maxima plugin works! Thank you!

Well, here are some more strange questions:

• Does maxima the only plugin which supports this sort of evaluation? I tried python, r, octave, but none will work.
• And are there some place where I can see which feature a plugin supports?

Giac works for me as well (I did 2+2).

I searched in the code (looking for one of the Giac menu items using ack, so that I would find where it is defined) and I _think_ I figured out a part of the answer: you have to look inside the ...-menus.scm Scheme file inside the progs subdirectory of the plugin.

Some of the plugins there use a  (if (not-in-session?) ...) clause where in the true branch they evaluate a (link scripts-eval-menu) form. I did not understand where the scripts-eval-menu is defined; the name has "scripts" inside, so maybe it does _that_; and Python does not have it.

• I noticed that cos<space>x will drive maxima mad, it requires me to add parents around x. But texmacs formulas have semantic information, and it could be used to improve the interface to CASs I think. So are there any CAS plugin which ultilizes this info?

I don't know and I am not able to figure it out in a short time, sorry. Perhaps one of the developers is listening and can tell you more.

TeXmacs is opaque sometimes; I am thinking of starting a Wikibook but if ever I do it, it will take time.
