Hi,

I’m on Rails 2.3.3 and using Haml 2.0.9 for my templates and  
Gettext-Rails 2.0.4 for the translation. Haml works like a charm and  
gettext is also working like it should.

But I cant get Gettext to parse Haml Files when using “rake updatepo”. I  
created a custom parser like this:

# lib/haml\_parser.rb

require ‘gettext\_rails/tools’  
require ‘haml’

# Haml gettext parser

module HamlParser  
module\_function

def target?(file)  
File.extname(file) == “.haml”  
end

def parse(file, ary = [])  
haml = Haml::Engine.new(IO.readlines(file).join)  
code = haml.precompiled.split(/$/)  
GetText::RubyParser.parse\_lines(file, code, ary)  
end  
end

GetText::RGetText.add\_parser(HamlParser)

My Rakefile looks like this:

# Rakefile

require(File.join(File.dirname( **FILE** ), ‘config’, ‘boot’))

require ‘rake’  
require ‘rake/testtask’  
require ‘rake/rdoctask’

require ‘tasks/rails’

desc “Create mo-files for L10n”  
task :makemo do  
require ‘gettext\_rails/tools’  
GetText.create\_mofiles(true) #(true, “po”, “locale”)  
end

desc “Update pot/po files to match new version.”  
task :updatepo do  
require ‘gettext\_rails/tools’  
require ‘haml\_parser’  
MY\_APP\_TEXT\_DOMAIN = “APP”  
MY\_APP\_VERSION = “APP 1.1.0”  
GetText.update\_pofiles(MY\_APP\_TEXT\_DOMAIN,  
Dir.glob(“{app,lib}/\*\*/\*.{rb,rhtml,html.erb,haml,html.haml,rjs}”),  
MY\_APP\_VERSION)  
end

This follows the known approach for parsing Haml files (  
[http://www.paulgillard.me.uk/2008/3/8/rails-haml-and-gettext](http://www.paulgillard.me.uk/2008/3/8/rails-haml-and-gettext) ).

The problem: No MessageIds are recognized from my Haml files. I checked  
with “puts” in the Haml-Parser if it tried the right files, could parse  
them and so on. Everything seemed to be fine, it just recognize anything  
and always returned only the already found msgids and for the Haml file  
an empty Array.

The strange thing: When I enter this in my console, everything works:

$$ script/console  
Loading development environment (Rails 2.3.3)

> > require ‘gettext\_rails/tools’  
> > =\> []  
> > require ‘haml’  
> > =\> []  
> > file = “app/views/sessions/new.haml”  
> > =\> “app/views/sessions/new.haml”  
> > haml = Haml::Engine.new(IO.readlines(file).join)  
> > =\> #\<Haml::Engine:0x4254104 @tab\_change=0, @block\_opened=false, @inden  
> > […]  
> > code = haml.precompiled.split(/$/)  
> > =\> [" content\_for :head do;", "\nhaml\_temp = stylesheet\_link […]  
> > GetText::RubyParser.parse\_lines(file, code, [])  
> > =\> [[“Login”, “app/views/sessions/new.haml:4”], […]

As you can see everything works here (I left out the long returns). I’m  
kind of freaking out why this isn’t the case in my Rake Task.

Anyone has an idea? You would really make me a happy Nerd!

Thanks!
