[completion] Revamp completion API
* _fzf_complete is the helper function for custom completion
* _fzf_complete FZF_OPTS ARGS
* Reads the output of the source command instead of the command string
* In zsh, you can use pipe to feed the data into the function, but
it's not possible in bash as by doing so COMPREPLY is set from the
subshell and thus nullified
* Change the naming convention for consistency:
* _fzf_complete_COMMAND
e.g.
# pass completion suggested by @d4ndo (#362)
_fzf_complete_pass() {
_fzf_complete '+m' "$@" < <(
local pwdir=${PASSWORD_STORE_DIR-~/.password-store/}
local stringsize="${#pwdir}"
find "$pwdir" -name "*.gpg" -print |
cut -c "$((stringsize + 1))"- |
sed -e 's/\(.*\)\.gpg/\1/'
)
}
# Only in bash
complete -F _fzf_complete_pass -o default -o bashdefault pass
