Hi Paul,
I've now upgraded to Emacs 24.3.1 and played a bit with your axiom-
environment.
First a short remark. I think it is a really big drawback that your
mode is only for Emacs24, because even on Ubuntu 13.10 an "apt-get
install emacs" will install Emacs23. I explicitly had to say "apt-
get install emacs24".
That in turn means, the FriCAS project cannot simply try to take
your code as the basis for efricas.
Yes, it is unfortunate that Emacs23 still seems to be the default in a
lot of places, but life is short and time is limited (and the world
will eventually catch-up) so I'm afraid back-porting to Emacs23 is not
really on my agenda.
Sorry if that seems a bit harsh, but we all have to prioritize our own
personal activities, and there are other things I'd rather be doing.
However, if someone else wants to look into it then of course I
wouldn't try to stop them :-)
I haven't really played long enough with your emacs mode to be able
to say deep things, but the source code itself looks quite nice. In
fact, I wonder whether you would be interested to write something
similar for editing aldor files.
I have hacked together an aldor-mode (http://hemmecke.org/aldor/
emacs). Works for me, but it's actually not as nicely written as
your axiom-environment code.
I looked at Aldor briefly a month or two ago, but couldn't get it to
compile on my platform (Mac OSX), so gave up :-(
I didn't try very hard though, and think that perhaps I should try
again, putting some effort into it this time. Is there much activity
on the Aldor-development front? The mailing list seems to be very
quiet recently.
Looking into themes/fricas-on-sbcl-theme.el shows me that you seem
to rely on the fricas promt having the form
(nnn) ->
Probably OK, but I guess, it would be better to do similar to what
Martin Rubey has done in the current underlying efricas mode, i.e.
to use the hook mechanism of fricas to inject some special character
sequences into the output so that finding the prompt would be more
reliable. However, maybe it's unnecessary.
Actually, the reliability of this prompt-spotting scheme did leave me
feeling a little uneasy, but it seemed to work okay so I went with
it. If there is a better mechanism available in FriCAS then it would
be good if I used it. Is it documented anywhere, or should I look at
the efricas.el code?
What would be cool... if editing .input files, it should be possible
to type something like Ctrl-ENTER to send the current line to a
fricas session. Even more cool, if I could thus send a multiline
function definition.
Yes, something like this would be nice. Jiazhaoconga mentioned
something similar. This really should be the next thing I do...
Regards,
Paul
