Camping - super tiny MVC framework that's 4K!

Anyone heard of it before?

Camping is a small web framework, less than 4k, a little white blood cell in the vein of Rails. See it for yourself. Most camping apps are just one single file, packed full of Vitamins MVC and b12. A pocket full of tricks to free you of the globally namespaced doom of Sinatra, and the complexity of Rails. Camping and Rails are good friends though, so you can be sure if you ever outgrow your tent, Rails will help make your app the Next Big Thing™.

Camping has been around for a long time. It was originally one of _why’s projects. He wanted to write as small of a web framework as he could. I seem to recall that it used a lot of neat ruby tricks (overloading operators and meta-programming hacks).

Ah right, I hadn’t heard of it before. Here’s the code

# == About camping.rb
#
# Camping comes with two versions of its source code.  The code contained in
# lib/camping.rb is compressed, stripped of whitespace, using compact algorithms
# to keep it tight.  The unspoken rule is that camping.rb should be flowed with
# no more than 80 characters per line and must not exceed four kilobytes.
#
# On the other hand, lib/camping-unabridged.rb contains the same code, laid out
# nicely with piles of documentation everywhere. This documentation is entirely
# generated from lib/camping-unabridged.rb using RDoc and our "flipbook" template
# found in the extras directory of any camping distribution.
