A Haml server for web designers
I have a script named serve in my bin directory that let's me quickly startup a Webrick server in any directory. This is handy for serving HTML mockups or other files. Today, updated it to work with Haml:
#!/usr/bin/env ruby
require 'webrick'
require 'rubygems'
require 'haml'
class HamlHandler < WEBrick::HTTPServlet::AbstractServlet
def initialize(server, name)
super
@script_filename = name
end
def do_GET(req, res)
begin
data = open(@script_filename){|io| io.read }
res.body = parse_haml(data)
res['content-type'] = 'text/html'
rescue StandardError => ex
raise
rescue Exception => ex
@logger.error(ex)
raise HTTPStatus::InternalServerError, ex.message
end
end
alias do_POST do_GET
private
def parse_haml(string)
engine = Haml::Engine.new(string,
:attr_wrapper => '"',
:filename => @script_filename
)
engine.render
end
end
WEBrick::HTTPServlet::FileHandler.add_handler("haml", HamlHandler)
args = ARGV.join(' ')
args.gsub!(%r{^http://}, '')
args = args.split(/[ :]/).compact
server = WEBrick::HTTPServer.new(
:Port => args.pop || 3000,
:BindAddress => args.pop || '0.0.0.0',
:DocumentRoot => Dir.pwd
)
trap("INT") { server.shutdown }
server.start#!/usr/bin/env ruby
require 'webrick'

require 'haml'
class HamlHandler < WEBrick::HTTPServlet::AbstractServlet

super
@script_filename = name
end
def do_GET(req, res)

server.startComments
