Is it possible to "watch" Haml files in Compass (stylesheet authoring tool)? - haml

Question

Currently, Compass is watching the .scss files inside the src folder and automatically updating the cs files. (by typing compass watch myproject).
Is there any way of including haml files in the "watching process"?
(I couldn't install StaticMatic because I don't want to install Ruby1.8).

Answer 1

Firstly, you should be using RVM. Installing any version of Ruby becomes painless.
Secondly, I just wrote this for myself, using the same 'fssm' gem that Compass uses to watch files. Add this to your / create a Rakefile:
require 'rubygems'
require 'fssm'
require 'haml'
class HamlWatcher
class << self
def watch
refresh
puts ">>> HamlWatcher is watching for changes. Press Ctrl-C to Stop."
FSSM.monitor('haml', '**/*.haml') do
update do |base, relative|
puts ">>> Change detected to: #{relative}"
HamlWatcher.compile(relative)
end
create do |base, relative|
puts ">>> File created: #{relative}"
HamlWatcher.compile(relative)
end
delete do |base, relative|
puts ">>> File deleted: #{relative}"
HamlWatcher.remove(relative)
end
end
end
def output_file(filename)
# './haml' retains the base directory structure
filename.gsub(/\.html\.haml$/,'.html')
end
def remove(file)
output = output_file(file)
File.delete output
puts "\033[0;31m remove\033[0m #{output}"
end
def compile(file)
output_file_name = output_file(file)
origin = File.open(File.join('haml', file)).read
result = Haml::Engine.new(origin).render
raise "Nothing rendered!" if result.empty?
# Write rendered HTML to file
color, action = File.exist?(output_file_name) ? [33, 'overwrite'] : [32, ' create']
puts "\033[0;#{color}m#{action}\033[0m #{output_file_name}"
File.open(output_file_name,'w') {|f| f.write(result)}
end
# Check that all haml templates have been rendered.
def refresh
Dir.glob('haml/**/*.haml').each do |file|
file.gsub!(/^haml\//, '')
compile(file) unless File.exist?(output_file(file))
end
end
end
end
namespace :haml do
desc "Watch the site's HAML templates and recompile them when they change"
task :watch do
require File.join(File.dirname(__FILE__), 'lib', 'haml_watcher')
HamlWatcher.watch
end
end
Run it with:
rake haml:watch
