Generate file from YAML data with mustache layout.

gistfile1.rb

#!/usr/bin/ruby
 
require 'mustache'
require 'yaml'
 
 
LAYOUT = 'layout.html'
DATA   = 'data.yaml'
OUT    = 'index.html'
 
 
class File
    def self.read(path)
        File.open(path) { |f| f.read }
    end
 
    def self.write(path, content)
        File.open(path, 'w') { |f| f.write(content) }
    end
end
 
 
task :default => [:build]
 
task :build do
    print "generating #{OUT} ..."
 
    layout = File.read(LAYOUT)
    data = YAML.load_file(DATA)
    content = Mustache.render(layout, data)
    File.write(OUT, content)
 
    print ' done!'
end

You need to run gem install mustache to use this script.
