Description¶ ↑

Retic is a tiny View-Controller framework for CGI. This can be used by single .rb file without any external libraries.

Example¶ ↑

CGI file:

#!/usr/bin/ruby
require 'retic.rb'

class YourWebApp < Retic
  def do_index
  end
  def do_echo
    {:input => param('input')}
  end
end
YourWebApp.run

Template file (templates/index.erb.html):

<form action="<%= @self_url%>">
<input type="text" name="input">
<input type="submit" value="echo!">
<input type="hidden" name="action" value="echo">
</form>

Template file (templates/echo.erb.html):

<p>your input: <b><%= h(@input) %></b><p>

Variables in template¶ ↑

There variables are provided on default;

• @self_url - current CGI URL without query string

• @controller - current controller instance

• @cgi - current cgi instance

To change default variable, override default_vars method.

You can return a hash from action methods (do_ACTIONNAME) to add variables for template.
