;;;;FILE: pjb-erc.el
;;;;LANGUAGE: emacs lisp
;;;;SYSTEM: POSIX
;;;;USER-INTERFACE: NONE
;;;;DESCRIPTION
;;;;
;;;; ERC stuff.
;;;;
;;;; Don't worry anymore about flooding a channel!
;;;;
;;;; This yank function for erc uses lisppaste when the text to yank
;;;; is more than *erc-yank-flood-limit* lines long.
;;;;
;;;; If the text is below this limit, it's yanked using the function
;;;; set in *erc-yank-function* (eg. can be yank or delete-region-and-yank).
;;;;
;;;; Otherwise, if the current buffer is one of the buffer where lisppaste
;;;; works, then use lisppaste on this buffer (and let lisppaste send its
;;;; notification message; the Title is taken as the first non empty line
;;;; of the pasted text).
;;;;
;;;; Otherwise, the text is pasted to the "None" lisppaste channel, and the
;;;; url of the lisppaste is yanked into the current buffer.
;;;;
;;;; You can safely use:
;;;; (global-set-key (kbd "C-y") (function erc-yank))
;;;; or just add it to some erc buffer hook.

;;;;MODIFICATIONS
;;;; 2006-11-15 <PJB> Extracted from ~/.emacs; Fusioned erc-yank.el
;;;; 2006-10-23 <PJB> Updated for the new anti-spam lisppaste feature.
;;;; 2006-05-15 <PJB> Created.
;;;;BUGS
;;;; We should check if there's a recent paste with same title, and
;;;; if there is, add: annotate=#pastenumber to get an annotation.
