# problem :
# was trying to import a 3D model in a web page in json format for use with threejs : https://github.com/mrdoob/three.js 
# 3D model was exported from maya using this threejs plugin # https://github.com/mrdoob/three.js/tree/master/utils/exporters/maya 
# exported json had two problems: 
# 1. all of it was in one line, i.e no indents 
# 2. float values inside keys were not quoted i.e stringified. 
# here's the snippet, it converts the 'bad' json to 'good' ( quoted json ) 


@parsed = JSON.parse(Rails.root.join("app","assets","javascripts","model.js").read)

In August 2007 a hacker found a way to expose the PHP source code on facebook.com. He retrieved two files and then emailed them to me, and I wrote about the issue:

http://techcrunch.com/2007/08/11/facebook-source-code-leaked/

It became a big deal:

The two files are index.php (the homepage) and search.php (the search page)

Retaining line numbers with the Rails asset pipeline

By default the Rails 3 asset pipeline uses the Uglifier gem to optimize and minify your Javascript. One of its many optimisations is to remove all whitespace, turning your Javascript into one very long line of code.

Whist removing all the newlines helps to reduce the file size, it has the disadvantage of making your Javascript harder to debug. If you've tried to track down Javascript errors in minified Javascript files you'll know the lack of whitespace does make life harder.

Luckily there is a simple solution: to configure Uglifier to add newlines back into the code after it performs its optimisations. And if you're serving your files correctly gzip'd, the newlines add only a small increase to the final file size.

You can configure Uglifier to add the newlines by setting the following in your Rails 3 config/production.rb file:
