The Result

Fenced code blocks inside ordered and unordered lists

This is a numbered list.
I'm going to include a fenced code block as part of this bullet:

$PATH in MacOSX 10.7

MacOSX has a truly global path setting that precedes any other setting like ~/.bash_profile. The file /private/etc/paths is a list of pathnames. The order from top to bottom defines the resulting order in the $PATH variable. After loading /private/etc/paths there is a directory /private/etc/paths.d/ with files in the same style. Those are appended to the $PATH variable.

The default content of /private/etc/paths looks like this:

/usr/bin

/bin

Problem: When linking to the raw version of a gist, the link changes with each revision.

Solution:

To return the first file from a gist: https://gist.github.com/[gist_user]/[gist_id]/raw/

Example: https://gist.github.com/atenni/5604522/raw/
Works even when you change the filename.

To get a file from multi–file gist: https://gist.github.com/[gist_user]/[gist_id]/raw/[file_name]

	var http = require("http"),
	url = require("url"),
	path = require("path"),
	fs = require("fs")
	port = process.argv[2] \|\| 8888;

	http.createServer(function(request, response) {

	var uri = url.parse(request.url).pathname
	, filename = path.join(process.cwd(), uri);

	# you have ctags but it does not work...
	$ ctags -R --exclude=.git --exclude=log *
	ctags: illegal option -- R
	usage: ctags [-BFadtuwvx] [-f tagsfile] file ...

	#you need to get new ctags, i recommend homebrew but anything will work
	$ brew install ctags

	#alias ctags if you used homebrew
	$ alias ctags="`brew --prefix`/bin/ctags"
