EmacsWiki: Elisp CookbookThis page contains snippets of code that demonstrate basic EmacsLisp programming operations in the spirit of the O’Reilly cookbook series of books. For every task addressed, a worked-out solution is presented as a short, focused, directly usable piece of code. All this stuff can be found elsewhere, but it is scattered about in libraries, manuals, etc. It would be helpful to have here in one spot.
