Hi,
I made a completion file for setxkbmap (a X utility to change keyboard
layout).
I have a few difficulties, so I'm not that happy with my completion script :
*: There are some options of setxkbmap I did not understand, and
therefore, I could not make completion suggestions.
*: setxkbmap allows layout to be specified either as first non-option
argument, either as argument to -layout option. In the same way, variant
can be specified either as second option, either as argument to
-variant. It looks quite unusual to me. As a matter of fact, setxkbmap
source does not call getopt, but has it own option parser. I did not
find a nice way to consider that behaviour with zsh completion, so I
simply discarded -variant and -layout option.
*: Another problem is that xkb files are in /usr/lib/X11/xkb (according
to setxkbmap manual), but are in /usr/share/X11/xkb on my linux
distribution. My workaround is :
for dir in /usr/lib/X11/xkb /usr/share/X11/xkb; do
if [ -d $dir ] ; then
sourcedir=$dir
break
fi
done
[ -d $sourcedir ] || return 1
Have you ever had this problem ?
How did you solve it ?
So, my script is far from perfect, but it's still quite useful for me.
May be it would be for other people so I submit it to you.
arno.
