I want to automatically clear all functions created from outer function.
auto-unset-funcs() {
# Don't leak any functions
typeset -ga ef
ef=( ${(k)functions} )
# No localtraps – sets in outside scope
trap "unset -f -- \"\${(k)functions[@]:|ef}\" &>/dev/null; unset ef" EXIT
trap "return 1" INT
}
Above code correctly clears new functions when pasted into the outer function. However, I would like to avoid pasting and simply do:
outer() {
emulate -L zsh
auto-unset-funcs
# freely define new functions…
}
However, the EXIT trap is executed when auto-unset-funcs exits, not when outer() does… I thought that lack of localoptions localtraps would declare the EXIT trap in the first function that has it (outer does, via emulate -L). Doing setopt localoptions nolocaltraps in auto-unset-funcs didn't help. Any ideas on having such auto-unset-funcs function?
