;;; lispxmp.el --- Automagic emacs lisp code annotation

;;; Commentary:
;;
;; Automagical annotation of lisp values like Ruby's xmpfilter. For
;; example, executing M-x lispxmp on the following buffer:
;;
;; ====
;; 1 ; =>
;; (+ 3 4) ; =>
;; (dotimes (i 3)
;;   (* i 4)  ; =>
;; )
;; ====
;; 
;; produces
;; 
;; ====
;; 1 ; => 1
;; (+ 3 4) ; => 7
;; (dotimes (i 3)
;;   (* i 4) ; => 0, 4, 8
;; )
;; ====


;;; Commands:
;;
;; Below are complete command list:
;;
;;  `lispxmp'
;;    Annotate value of lines containing `; =>' .
;;
;;; Customizable Options:
;;
;; Below are customizable option list:
;;
;;  `lispxmp-string-no-properties'
;;    *When non-nil, remove text priperties of strings in annotation.
;;    default = t

;;; Installation:
;;
;; paredit.el is optional. Get it from here:
;; http://mumble.net/~campbell/emacs/paredit.el
;;
;; Put lispxmp.el to your load-path.
;; The load-path is usually ~/elisp/.
;; It's set in your ~/.emacs like this:
;; (add-to-list 'load-path (expand-file-name "~/elisp"))
;;
;; And the following to your ~/.emacs startup file.
;;
;; (require 'lispxmp)
;;
;; No need more.

;;; Customize:
;;
;;
;; All of the above can customize by:
;;      M-x customize-group RET lispxmp RET
;;


;;; Bug Report:
;;
;; If you have problem, send a bug report via M-x lispxmp-send-bug-report.
;; The step is:
;;  0) Setup mail in Emacs, the easiest way is:
;;       (setq user-mail-address "your@mail.address")
;;       (setq user-full-name "Your Full Name")
;;       (setq smtpmail-smtp-server "your.smtp.server.jp")
;;       (setq mail-user-agent 'message-user-agent)
;;       (setq message-send-mail-function 'message-smtpmail-send-it)
;;  1) Be sure to use the LATEST version of lispxmp.el.
;;  2) Enable debugger. M-x toggle-debug-on-error or (setq debug-on-error t)
;;  3) Use Lisp version instead of compiled one: (load "lispxmp.el")
;;  4) Do it!
;;  5) If you got an error, please do not close *Backtrace* buffer.
;;  6) M-x lispxmp-send-bug-report and M-x insert-buffer *Backtrace*
;;  7) Describe the bug using a precise recipe.
;;  8) Type C-c C-c to send.
;;  # If you are a Japanese, please write in Japanese:-)
