How do you let them configure and extend your program?
As it stands now *every* program uses its own configuration language,
e.g.:
------------------------------
.Xdefaults:
#ifdef COLOR
*customization: -color
*background: ivory
#endif
.bashrc:
PS1=\$\ ; export PS1
LESSCHARSET=latin1; export LESSCHARSET
.calendar:
Calendar [v1.7]
Appt [
Start [480]
.doomrc:
sfx_volume 8
music_volume 8
.dvipsrc:
% teTeX's config.ps.
%
% Memory available.
m 1000000
.emacs:
(if window-system
(server-start)
)
.fvwm2rc
ClickTime 150
IconFont fixed
DeskTopSize 2x1
.screenrc
# Make the output buffer large for (fast) xterms.
termcapinfo xterm* OL=10000
.lynxrc:
# BY_DATE -- sorts on the date of the file
file_sorting_method=BY_FILENAME
user_mode=ADVANCED
.gdbint
# -*- sh -*-
# Define a bunch of useful functions for debugging Guile.
# Add more as required.
define dp
set $gp=gdb_print($arg0)
output gdb_output
echo \n
.inputrc:
set output-meta On
set convert-meta Off
And so on and so on.
------------------------------
It doesn't make sense to me to write yet another "scheme enabled
window manager", yet another "scheme enabled shell", yet another
"scheme enabled music editor".
I think it would be better to link fvwm2 with guile, write a (simple)
translator module which translates the fvwm2 config language to scheme
and let people play with this at run time.
The Gimp supports both, a scheme like syntax and a perl like syntax to
extend the program. Why do I have to link it against a perl interpreter
*and* a scheme interpreter to write scripts in perl/scheme syntax?
(Well, I think it's impossible to write a perl->scheme module, so this
might be okay :>)
Blender. Why do I have to learn the python syntax to write a simple
script? (The full power of python isn't available anyway).
Or the Bash. Why not write a sh->scheme translator and link the Bash
with Guile?
