Exactly =) Just put "fricas" in .TeXmacs/plugins and two other scripts in "~".
Oh, not quite...
I had to execute the commands appearing at the top of the fricas shell
script, namely
AXIOM='/home/hemmecke/software/lib/fricas/target/i686-pc-linux'
export AXIOM
PATH=${AXIOM}/bin:${PATH}
export PATH
otherwise the FriCAS menu item doesn't appear in the session menu of
texmacs.
But you cannot require someone to set the AXIOM variable manually. So
you better change fricas/progs/init-fricas.scm to something like this:
(plugin-configure fricas
(:require (url-exists-in-path? "fricas"))
;(:initialize (fricas-initialize))
(:launch "fricas -nosman")
(:session "FriCAS"))
Calling "fricas -nosman" has the same effect as calling AXIOMsys with
the AXIOM and PATH env variables set appropriately.
Second, you provided .axiom.input and texmacs.input. The standard init
script for Fricas is ~/.fricas.input . So I've now created this file
with content:
)set output algebra off
)set output texmacs on
)lisp (setf |$ioHook| (lambda (x &optional args) (cond ((eq x
'|startPrompt|) (princ (concat (code-char 2) "prompt#") )) ((eq x
'|endOfTeXmacsOutput|) (princ (concat (code-char 5) (code-char 10))))
((eq x '|startTeXmacsOutput|) (princ (code-char 2))) ((eq x
'|startKeyedMsg|) (princ (concat (code-char 2) "verbatim:"))) ((eq x
'|endOfKeyedMsg|) (princ (code-char 5))) ((eq x '|endOfPrompt|) (princ
(code-char 5) )) )))
)lisp (setf |$inputPromptType| '|plain|)
With the above modifications I can report to have a FriCAS running
inside TeXmacs. Nice!
There are a few issues remaining, though.
1) Since you don't start the sman process, there is no graphics
and no hyperdoc.
2) Globally changing ~/.fricas.input is not a good idea in my opinion.
As for 1) I have no idea why starting "fricas" instead of "fricas
-nosman" does not work. Maybe, because sman is starting AXIOMsys and
texmacs simply does not realize that sman is not giving back control.
For 2), I wish FriCAS had a way to run scripts specified on the command
line, i.e. something like "fricas -read texmacs.input".
