New fish completions

[Benjamin Martin]

Dear all,

I noticed the fish completions were not working correctly, mostly the function to get directory paths or files and the function to get gpg keys. There are a few other tweaks like completing both directories and files for generate, however, no other major changes. Here is the re-write I did with awk and find:

function __fish_pass_get_prefix
    set -l prefix "$PASSWORD_STORE_DIR"
    if [ -z "$prefix" ]
        set prefix "$HOME/.password-store"
    end
    echo "$prefix"
end

function __fish_pass_needs_command
    set -l cmd (commandline -opc)
    if [ (count $cmd) -eq 1 -a $cmd[1] = pass ]
        return 0
    end
    return 1
end

function __fish_pass_uses_command
    set cmd (commandline -opc)
    if [ (count $cmd) -gt 1 ]
        if [ $argv[1] = $cmd[2] ]
            return 0
        end
    end
    return 1
end

function __fish_pass_print_gpg_keys
    gpg2 --list-secret-keys | awk '/sec/{getline l1; getline l2; gsub(/ /, "",l1); print l1 "\011" l2}'
end

function __fish_pass_print_entry_dirs
    cd (__fish_pass_get_prefix); ls -d **/
end

function __fish_pass_print_entries
    cd (__fish_pass_get_prefix); find . -type f -name "*.gpg" | sed "s/\.\/\|.gpg//g"
end

function __fish_pass_print_entries_and_dirs
    __fish_pass_print_entry_dirs
    __fish_pass_print_entries
