Differences to Ruby's HAML

Not enough to worry about: all test cases found in the .json files of the original Ruby distribution pass. The differences are minor and intentional:

• HAML-TO-PHP sets escape_html to true by default
• No Ruby code is supported — you mix in PHP code instead
• Because HAML-TO-PHP renders more static content, some very rare specific cases behave differently. For example:

  %tag{ "#{foo()}" => "v1", "#{foo()}" => "v2"}

  Ruby's HAML only keeps one tag if foo() evaluates to the same value twice. HAML-TO-PHP will render the same tag twice. Fixing this would require evaluating more PHP code per request. If this matters, contact support.

• Line continuation (|) is not yet supported — could be fixed easily (→ contact support)
• Markdown support and similar filters are not included yet. You can add your own filters easily.
