Hello!<br>
<br>
Many/Some RoR folks swear at Haml/Sass (<a href="http://haml-lang.com/" target="_blank">http://haml-lang.com/</a>) and I<br>
see there is Hamlet project at Github<br>
(<a href="http://github.com/snoyberg/hamlet" target="_blank">http://github.com/snoyberg/hamlet</a>)<br>
<br>
saying "Haml-like template files that are compile-time checked", so<br>
I'm curious if it targets to be Haml-compatible or just "haml-like" ?<br>
<br>
<br>
Sincerely,<br>

<div><br></div><div>I'll put up a mini tutorial on it when it's polished, but there's really not much to the syntax. Just to give an idea of the niche it's trying to fill:</div><div><br></div><div>* Quasi-quoted templates are embeddable directly in your Haskell files and included in the binary.</div>
<div>* All variables are compile-time checked.</div><div>* Allows for on-demand loading of IO values, eg you can have conditionals in the template and only load data from a database if needed.</div><div>* It uses enumerators for looping, so it should fit nicely in memory.</div>
<div>* Deals with the string problem by having a very simple datatype: data Html = Encoded Text | Unencoded Text (Html will probably be renamed to something else).</div><div>* Has a monadic interface so you can use the nice features of the Hamlet monad without using the Hamlet syntax and quasi-quoter.</div>
<div>* Allows embedding of other templates.</div><div><br></div><div>The code for integration into Yesod is literally being written right now (just took a break to check my e-mail), so I should have more to say soon. If anyone's dying to know the details, send me an e-mail and I'll try to put together a blog post.</div>
