== Camping, a Microframework
Camping is a web framework which consistently stays at less than 4kb of code.
You can probably view the complete source code on a single page. But, you know,
it's so small that, if you think about it, what can it really do?
The idea here is to store a complete fledgling web application in a single file
like many small CGIs. But to organize it as a Model-View-Controller application
like Rails does. You can then easily move it to Rails once you've got it going.
A skeleton might be:
require 'camping'
module Camping::Models
class Post < Base; belongs_to :user; end
class Comment < Base; belongs_to :user; end
class User < Base; end
end
module Camping::Controllers
class Index < R '/'
def get
@posts = Post.find :all
render :index
end
end
end
module Camping::Views
def layout
html do
body do
self << yield
end
end
end
def index
for post in @posts
h1 post.title
end
end
end
if __FILE__ == $0
Camping::Models::Base.establish_connection :adapter => 'sqlite3', :database => 'blog3.db'
Camping::Models::Base.logger = Logger.new('camping.log')
Camping.run
end
Some things you might have noticed:
* Camping::Models uses ActiveRecord to do its work. We love ActiveRecord!
* Camping::Controllers can be assigned URLs in the class definition. Neat?
* Camping::Views describes HTML using pure Ruby. Markup as Ruby, which we
call Markaby.
If you want to write larger applications with Camping, you are encouraged to
split the application into distinct parts which can be mounted at URLs on your
web server. You might have a blog at /blog and a wiki at /wiki. Each
self-contained. But you can certainly share layouts and models by storing them
in plain Ruby scripts.
