Html2haml

Html2haml, not surprisingly, converts HTML to Haml. It works on HTML with embedded ERB tags as well as plain old HTML.

Installation

Add this line to your application's Gemfile:

gem 'html2haml'

And then execute:

$ bundle

Or install it yourself as:

$ gem install html2haml

Usage

To convert a project from .erb to .haml

If your system has sed and xargs available and none of your .erb file names have whitespace in them, you can convert all your templates like so:

find . -name \*.erb -print | sed 'p;s/.erb$/.haml/' | xargs -n2 html2haml

If some of your file names have whitespace or you need finer-grained control over the process, you can convert your files using gsed or multi-line script techniques discussed here.

Documentation

About version 2.0

Html2haml 2.0 differs from 1.x primarily in that it uses Nokgiri as its HTML parser rather than Hpricot. At the current time however, there are some problems running Html2haml 2.0 on JRuby due to differences in the way the Java version of Nokogiri parses HTML. If you are using JRuby you may wish to run HTML2Haml on MRI or use a 1.x version until these problems have been resolved.
