The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

jQuery / Twitter Bootstrap List Tree Plugin

Demo: http://jsfiddle.net/clayzermk1/QD8Hs/

Overview

I needed a simple plugin to build a two-tier collapsible list with checkboxes. I wanted it to fit well with Twitter's Bootstrap. I couldn't find one that was simple enough. I hope you enjoy =) Feel free to send feedback.

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

	# -- coding: utf-8 --
	from django import forms

	from crispy_forms.helper import FormHelper
	from crispy_forms.layout import Layout, Div, Submit, HTML, Button, Row, Field
	from crispy_forms.bootstrap import AppendedText, PrependedText, FormActions


	class MessageForm(forms.Form):
	text_input = forms.CharField()

	# The following recipe works with upstream rails proxy for custom 404s and 500s.
	# Errors are usually handled via rails except if proxy is really down, in which case
	# nginx needs a bit more configration.

	server {
	# ...

	location / {
	error_page 404 = @rails; # let rails show a page with suggestions
	try_files maintenance.html @rails;

	def run_pg_fouine():
	info = host_info[env.host_string]
	db_name = info.tags.get('Name')
	sudo('perl -pi -e "s/log_min_duration_statement = ./log_min_duration_statement = 0/" /etc/postgresql/9./main/postgresql.conf')
	sudo('/etc/init.d/postgresql reload')
	time.sleep(30)
	sudo('perl -pi -e "s/log_min_duration_statement = ./log_min_duration_statement = 500/" /etc/postgresql/9./main/postgresql.conf')
	sudo('/etc/init.d/postgresql reload')
	run('tail -n 100000 /var/log/postgresql/postgresql-9.*-main.log > /tmp/pgfouine.txt')
	run('gzip -f /tmp/pgfouine.txt')

	"""
	jQuery templates use constructs like:

	{{if condition}} print something{{/if}}

	Or like:

	{% if condition %} print {%=object.something %}{% endif %}

	This, of course, completely screws up Django templates,
