Re: Dynamic colored command in zsh

[Roy Zuo <roylzuo@gmail.com>]

Yes, I tried today and made some progress. I can make the color for the command
to change whenever I type a new character or delete one. However my ZLE skill is
quite limited and someone else might be able to make this also work when TAB is
pressed.

    recolor-cmd() {
        args=(${(z)BUFFER})
        cmd=$args[1]
        res=$(builtin type $cmd 2>/dev/null)
        [ -z $res ]  && return
        if [ $res =~ 'reserved word' ]; then
            color="magenta"
        elif [ $res =~ 'an alias' ]; then

            color="cyan"
        elif [ $res =~ 'shell builtin' ]; then
            color="yellow"
        elif [ $res =~ 'shell function' ]; then
            color='green'
        elif [ $res =~ "$cmd is" ]; then
            color="blue"
        else
            color="red"
        fi
        region_highlight=("0 ${#cmd} fg=${color},bold")
    }

    check-cmd-self-insert() { zle .self-insert && recolor-cmd }
    check-cmd-backward-delete-char() { zle .backward-delete-char && recolor-cmd }

    zle -N self-insert check-cmd-self-insert
    zle -N backward-delete-char check-cmd-backward-delete-char

Regards,

Roy
