Camping is a web application microframework written in Ruby which consistently stays under 4kb - the complete source code can be viewed on a single A4 sheet.
It was created and updated by _why until version 1.5. Around that time Why's focus shifted towards Hackety Hack and related project Shoes. _why provided Judofyr (a major contributor) with admin access on rubyforge.org and other sites. Judofyr took over as defacto head of the project. Since then Camping has been a community driven framework with contributions from many people and a small but helpful community. While Judofyr is sometimes seen as a leader, he's insisted camping be governed by consensus on the very active mailing list. Why's eventual departure solidified the project as being communally run, and is notable for being one of the few former why the lucky stiff projects to be taken over by the community before why's disappearance. Current editions of Camping are available from Github and are distributed as a RubyGem.
Camping stores a complete fledgling web application in a single file, like a bundle of many small CGI scripts, but organizes it as a model–view–controller application as Ruby on Rails does. Camping applications can stand alone, meet niche requirements as 'the small wheels' that serve larger setups, or easily be ported to Rails.
For a basic installation, Camping only requires Rack (0.3 or higher) and (if you want to write HTML) Markaby (0.5 or higher), both available as Rubygems. Further details can be found on the Camping wiki. To use a database (SQLite by default) you'll also need the ActiveRecord and Sqlite3-ruby Rubygems. Run
camping yourappname.rb to launch the application on port 3301.
The introductory tutorial builds a minimal unstyled wiki (download working example wiki code), and the Camping examples contains a tiny but fully functioning css-styled blog. Earlier Camping 1.5 examples will either run without modification or require only slight adjustments to run under Camping 2.0.
