Emacs

snippets

Here are some emacs tips that I've stolen/written/butchered.

Emacs modules I've written:

xmlgen.el: Produce XML from a sexp.
etest: ETest lets you define tests in a domain specific, hierarchical manner and gather results in a simple, structure of the same shape.
prove.el: A perl compilation mode with syntax highlighting, folding and the usual compilation stuff.
figlet.el: Anger your co-workers by checking in ascii-art text to trunk. Then blame it on this module 'cos it made it so easy.
project-root.el: Define 'projects' with elisp and act accordingly when a file contained within a project is 'hit'.
org-annotate-file.el: This is yet another implementation to allow the annotation of a file without modification of the file itself. The annotation is in org syntax so you can use all of the org features you are used to.
ack.el: ack.el provides a simple compilation mode for the perl grep-a-like ack. It has the ability to guess what files you want to search for based on the major-mode.
find-cmd.el (part of GNU emacs): Click through for a slightly detailed description or just go for the module.
org-irc.el (part of GNU emacs): This file implements links to an IRC session from within Org-mode. Org-mode loads this module by default - if this is not what you want, configure the variable `org-modules'.
