;;; Commentary:

;; Provides pcompletion for the `rake' command, which is basically
;; `make' implemented in Ruby.

;;; Code:

(require 'pcomplete)

;;;###autoload
(defun pcomplete/rake ()
  "Completion rules for the `ssh' command."
  (pcomplete-here (pcmpl-rake-tasks)))

(defun pcmpl-rake-tasks ()
   "Return a list of all the rake tasks defined in the current
projects.  I know this is a hack to put all the logic in the
exec-to-string command, but it works and seems fast"
   (delq nil (mapcar '(lambda(line)
			(if (string-match "rake \\([^ ]+\\)" line) (match-string 1 line)))
		     (split-string (shell-command-to-string "rake -T") "[\n]"))))

(provide 'pcmpl-rake)
