zsh vcs_info recipe

[danielshahaf]

I use vcsh in conjunction with zsh and vcs_info and I'd like to share the following recipe:

zstyle -e ':vcs_info:git+post-backend:*' hooks 'reply=( ${${(k)functions[(I)[+]vi-git-post-backend*]}#+vi-} )'
+vi-git-post-backend-vcsh() {
  if git config --get 'vcsh.vcsh' > /dev/null; then
    hook_com[branch]+="%f/vcsh${GIT_DIR:+":${${GIT_DIR:t}%.git}"}" # %f ends coloring
  fi
}

With this recipe, after doing vcsh enter foo, the vcs_info prompt says (git)-[master/vcsh:foo]- rather than (git)-[master]-.
