Lua Haml

About

Lua Haml is an implementation of the Haml markup language for Lua.

A Haml language reference can be found here.

A basic haml tutorial can be found here

This repository is modified version of here

Lua Haml implements almost 100% of Ruby Haml, and attempts to be as compatible as possible with it, with the following exceptions:

Your script blocks are in Lua rather than Ruby, obviously.
A few Ruby-specific filters are not implemented,
namely :maruku, :ruby and :sass.
No attribute methods. This feature would have to be added to Ruby-style
attributes, which are discouraged in Lua-Haml, or the creation of a
Lua-specific attribute format, which I don't want to add.
No object reference. This feature is idiomatic to the Rails framework and
doesn't really apply to Lua.
No ugly mode. Because of how Lua Haml is designed, there's no performance
penalty for outputting indented code, so there's no reason to implement this
option.

Here's a Haml template that uses most of Lua Haml's features.

TODO

Lua Haml is now feature complete, but is still considered beta quality. That said, I am using it for a production website, and will work quickly to fix any bugs that are reported. So please feel free to use it for serious work, just not the Space Shuttle, ok? And very welcome any patch.

Hacking it

Before run the specification test, you need to install lpeg module and json modules

To run test, do this:

lua test.lua

To convert haml to html, do this:

lua bin/luahaml sample.haml > sample.html

To run bench, do this:

lua bench.lua sample.haml 10000
