Cleaner zsh completion

Created by: jamesk

Hi, love autojump, I've just started using it with zsh (and oh-my-zsh) and I had what seemed like a bug in the completion, duplicate folder entries. The completion also automatically added __ to my command as all results from autojump -complete start with the search term and __.

Anyway, posting this in case it affects anyone else / you want to incorporate it into autojump. This is my modified _j file:

#compdef j
cur=${words[2, -1]}

integer i=1
declare -A displayMap

autojump --complete "${=cur[*]}" | while read c; do
    hidden=$(echo "$c" | sed 's/\(.*__[0-9][0-9]*__\).*/\1/')
    display=$(echo "$c" | sed 's/.*__[0-9][0-9]*__\(.*\)/\1/')

    (( $+displayMap[$display] )) && continue
    displayMap[$display]=true

    compadd -V $i -U -i "$hidden" "$display";
    i=$((i+1))
done

(( $i > 2 )) && compadd -V $i -U "${=cur[*]}"

Modifications:

• It doesn't display the XXX__N__ prefix
• Maintains order via -V arg to compadd
• If there is more than one result: adds a final auto completion entry equal to the user's current argument, this stops the completion from modifying the command until the user actually selects one of the options.
