tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

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

# Render Partials in ECO-Templates like in Rails-ERB
# 
# usefull to clean up structure in spine.js and other js-mvc´s like backbone 
# 
# usage:
#   <%- render_partial 'path/to/partial' %>  ..  will render ../spine-app/views/path/to/_partial.jst.eco
#   <%- render_partial 'path/to/partial', foo: 'bar' %>  ..  will render ../spine-app/views/path/to/_partial.jst.eco  ..  locals = @foo 
#
window.render_partial = ( path, options = {} ) ->
	# add the leading underscore (like rails-partials)

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 = git@github.com: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:

#
# Place this code to your .profile, .bashrc, .bash_profile or whatever

program_exists () {
	type "$1" &> /dev/null ;
}


if program_exists go; then

Installing a Gem on Heroku from a Private GitHub Repo

Sometimes you want to use a gem on Heroku that is in a private repository on GitHub.

Using git over http you can authenticate to GitHub using basic authentication. However, we don't want to embed usernames and passwords in Gemfiles. Instead, we can use authentication tokens.

1. Get an OAuth Token from GitHub

First you will need to get an OAuth Token from GitHub using your own username and "note"

My issues with Modules

In researching topics for RailsCasts I often read code in Rails and other gems. This is a great exercise to do. Not only will you pick up some coding tips, but it can help you better understand what makes code readable.

A common practice to organize code in gems is to divide it into modules. When this is done extensively I find it becomes very difficult to read. Before I explain further, a quick detour on instance_eval.

You can find instance_eval used in many DSLs: from routes to state machines. Here's an example from Thinking Sphinx.
