run-help git subcommand

run-help git subcommand

[Jörg Sommer]

Hi,

is it possible to lookup the help for “git subcommand” as “run-help
git-subcommand”. My idea was to access the buffer stack in run-help to
get the subcommand but this doesn't work.

[[ $1 == "." ]] && 1="dot"
[[ $1 == ":" ]] && 1="colon"
if [[ $1 == git ]]; then
    local full_cmd
    getln full_cmd
    print -z "$full_cmd"
    i=0
    while [[ $i -lt $#full_cmd ]]; do
        case $full_cmd[$i] in
          -*|git) ;;
          *)
            1=git-"$full_cmd[$i]"
            break
            ;;
        esac
        ((++i))
    done
fi

How can I make ESC-H runs git-subcommand for git subcommand?

Thanks, Jörg.

Yes, it is and I expanded it for svn/svk. Here is my patch for run-help:

zsh is really cool!
