Update: I had inadvertently used string-join, a function provided by something in my ~/.emacs.d. The script has been updated to work with a vanilla Emacs (23, but should work with 22 as well).

Update #2 [2007.08.10]: Editing cheats and diffs have been implemented.

Update #3 [2007.08.21]: I added completion to cheat.el. The file linked on this page is still the latest version.

We all know and love cheat. Now you can cheat without leaving Emacs (and without using a shell in Emacs).

Just save cheat.el in ~/.emacs.d and then (require 'cheat) in your ~/.emacs. I also bind C-z C-c to cheat, you may want to do something similar.

, and for most of the commands the cheat command itself is used. Now you can do everything the command line client does from within Emacs, though you may need to revert to using cheat-command (described below).

Here's the rundown:

Any time you enter a cheat name there are both completion and a cheat-specific history available. Unless you are adding a new cheat. In that case you should use a new, unique name (duh).

• cheat – Lookup a cheat sheet interactively (cheat <name>)
  • cheat-sheets – List all cheat sheets (cheat sheets)
  • cheat-recent – List recently added cheat sheets (cheat recent)
  • cheat-versions – List versions of a cheat sheet interactively (cheat <name> --versions)
  • cheat-clear-cache – Clear all cached sheets.
  • cheat-add-current-buffer – Add a new cheat using the specified name and the contents of the current buffer as the body. (cheat <name> --add)
  • cheat-edit – Retrieve a fresh copy of the named cheat and display the body in a buffer for editing.
  • cheat-save-current-buffer – Save the current cheat buffer, which should be named *cheat-<name>*.
  • cheat-diff – Show the diff between the current version and the given version of the named cheat. If the version given is of the form m:n then show the diff between versions m and n. (cheat <name> --diff <version>)
  • cheat-command – Pass any arguments you want to cheat interactively.

(Added) I may add support for --diff and --edit in the future.

Please do send me your patches so everyone can benefit from them.
