Hmph. Why so much duplication with __gitcompadd, though.
I would have expected that this "append" behaviour to be done at the
lower level by introducing __gitcompappend that does not forcibly
truncate by starting from a hard-coded i=0, i.e. a collection of
small helper functions plus a single implementation of the logic to
push elements into COMPREPLY[] in __gitcompappend, perhaps like
these:
__gitcompappend () {
local i=${#COMPREPLY[@]}
for x in $1; do
if [[ "$x" == "$3"* ]]; then
COMPREPLY[i++]="$2$x$4"
fi
done
}
__gitcompadd () {
COMPREPLY=()
__gitcompappend "$@"
}
__gitcomp_nl_append () {
local IFS=$'\n'
__gitcompappend "$1" "${2-}" "${3-$cur}" "${4- }"
}
__gitcomp_nl () {
COMPREPLY=()
__gitcomp_nl_append "$@"
}
Is it because going this route and doing it at such a low level
would make zsh completion (which I have no clue about ;-)
unnecessarily complex?
