Haml for Grails anyone?

[Jim Morris]

Hi, I'm porting a Merb app to grails, and all my views are of course
in HAML. GSP sends shivers down my spine ;) Has anyone looked into a
version of HAML for Grails?

At a pinch I suspect I can modify haml2html and get = to generate the
tags, then compile the gsp pages from haml.

Anyone else any ideas?

Thanks

A generic haml specification is being worked on here:

There's some discussion about such matters on the haml-dev mailing list.

You might be able to do something by accessing the Ruby implementation via JRuby... that'd give you a weird mix of languages, though. As far as I know, there's no native Groovy implementation of Haml (yet).

I have a mostly complete implementation of Haml for Lua
(http://github.com/norman/lua-haml) which supports embedding and
rendering other languages, and it would probably be pretty
straightforward to add support for Groovy syntax. Since you can use
regular Java code inside Groovy, I imagine it wouldn't be too hard to
tie them together using LuaJava
(http://www.keplerproject.org/luajava/).

Lua was designed to be used as an embedded scripting language inside
other languages, and so that has guided the way I designed LuaHaml.
I'd be happy to try to help you make it work if you're interested.

Thanks Guys,

I'll take a look at the references, and let you know how I go about
it.

The ideas behind JSP/GSP are a little different (and UGLY), so I need
to get a little deeper into how Grails does its rendering, then I'll
see if using Haml dynamically to render istead of GSP, or use it
statically to compile equivalent GSP pages.

I did see a post somewhere that someone had tried a while back and
said they failed, but no reasons given to the roadblocks they hit.

Thanks
