I don't understand you guys. Of course, it would be good to have a commandline way to start arbitrary code before the fricas input line appears, but isn't

(:launch "cd ~/.TeXmacs/plugins/fricas; fricas -nosman")

enough to start FriCAS from TeXmacs in an appropriate way?

I suppose if all the parts are distributed with TeXmacs, the :launch path will be something like "/usr/share/texmacs/TeXmacs/plugins/fricas".
Is that a problem?

Of course a fricas user might expect that the current working directory does not change, i.e. he might expect that the fricas working directory is the same as from where he started texmacs. But honestly, I wouldn't trust that assumption if I start another program (fricas) from within a program (texmacs). Furthermore, doing in fricas something that involves interaction with the filesystem is probably not the primary use case.

And the advantage of my suggestion from above is that you can do it even with current (unpatched versions of fricas) no need to wait. And it is probably also not going away in any future version of fricas.
