Html2haml, not surprisingly, converts HTML to Haml. It works on HTML with embedded ERB tags as well as plain old HTML.
Add this line to your application's Gemfile:
gem 'html2haml'
And then execute:
$ bundle
Or install it yourself as:
$ gem install html2haml
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.
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.
Here are the options currently available to Html2haml:
