#
# Usage:
#  - Set `$PROJECT_PATHS` in your ~/.zshrc
#    e.g.: PROJECT_PATHS=(~/src ~/work)
#  - In ZSH you now can open a project directory with the command: `pj my-project`
#    the plugin will locate the `my-project` directory in one of the $PROJECT_PATHS
#    Also tab completion is supported.
#  - `pjo my-project` will open the directory in $EDITOR
#

function pj() {
  cmd="cd"
  file=$1

  if [[ "open" == "$file" ]] then
    shift
    file=$*
    cmd=(${(s: :)EDITOR})
  else
    file=$*
  fi

  for project in $PROJECT_PATHS; do
    if [[ -d $project/$file ]] then
      $cmd "$project/$file"
      unset project # Unset project var
      return
    fi
  done
  echo "No such project $1"
}

alias pjo="pj open"

function _pj () {
  # might be possible to improve this using glob, without the basename trick
  typeset -a projects
  projects=($PROJECT_PATHS/*)
  projects=$projects:t
  _arguments '*:file:($projects)'
}
