Prereq:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

One-line Tree in Python

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!

Snippets: Build a flat json file for handlebars.js template or jquery-vertical-timelines

UPDATED I've made some updates to the handlebars-json.py script.

• Script now accepts a "usage" argument for "handlebars" or "timeline" or "array"
• Script assumes a header row and strips underscores and spaces and converts header fields to lowercase when creating keys.
• Because the resulting JSON file can also be used to power Vertical Timelines, I've re-named the script to csv-to-json.py.
• The handlebars-json-csvkit.py script remains unchanged. I will attempt to re-work it to create handlebars or timeline JSON in the coming weeks.

See more in the Usage section below.
