Some questions about working with Haml

Question

I am trying to use Haml with Grails but I am having some issues.

The plugin for haml has errors to parse empty lines. The plugin generate gsp files, so I think that I can use the online haml html generator.

Bug I want something like an editor with syntax highlighting, blocks, etc, and that generate html.

Is there something like this? Or only the editor?

thanks in advance
