Hamlit

Hamlit is a high performance haml implementation.

Installation

Add this line to your application's Gemfile:

gem 'hamlit'

or just replace gem "haml" with gem "hamlit".

Features

Fast rendering

Hamlit's rendering is 7.0x times faster than original haml.

   hamlit:    94047.0 i/s
   erubis:    87136.3 i/s - 1.08x slower
     slim:    83996.0 i/s - 1.12x slower
     faml:    68861.1 i/s - 1.37x slower
     haml:    13428.6 i/s - 7.00x slower

This benchmark is the same as slim-template/slim's one for fairness.

Better parser

Haml's attribute parser is not so good. For example, raises syntax error for %a{ b: '}' }. Hamlit's attribute parser is implemented with Ripper, which is an official lexer for Ruby, so it can able to parse such an attribute.

Passing haml-spec

haml/haml-spec is a basic suite of tests for Haml interpreters. For all test cases in haml-spec, Hamlit behaves the same as Haml (ugly mode only, which is used on production).
