gemdoc completion in zsh
This week I stumbled upon Stephen Celis’ awesome bit of shell-fu, gemdoc, which allows you to quickly get to the HTML docs for installed gems via command-line. Unfortunately I abandoned bash years ago for zsh and Stephen’s shell bits needed a little porting. For me, zsh, is a bit like swiss-army knife where about 95% of it is a mystery to me, but the 5% I use I couldn’t live without. So simply switching back to bash is a no-go.
My setup is little-bit complicated, but I believe the following, stripped-down, recipe should work:
GEMDIR=$(gem env gemdir)
OPEN=$(whence xdg-open || whence open)
gemdoc() {
${OPEN} $GEMDIR/doc/`$(which ls) $GEMDIR/doc | grep $1 | sort | tail -1`/rdoc/index.html
}
_gemdocomplete() {
reply=( `$(which ls) $GEMDIR/doc` )
}
compctl -K _gemdocomplete gemdoc
