Hpaste.el

hpaste.el is an Emacs Lisp library that integrates hpaste into Emacs. It provides two functions, hpaste-paste-region and hpaste-paste-buffer, which send the region or buffer to the hpaste server as required. Most things are customisable: do M-x customize and browse to the Hpaste group to see what you can change. Code is available under the GPL license. (see the talk page for a makefile allowing you to keep up-to-date on this programatically). Enjoy!

Update 13 Mar 08: display URL of paste in minibuffer, and add it to kill ring.

Update 13 Dec 07: fixed problems with "Wrong type argument: stringp, nil" appearing after pasting.
