# Haml.js
High performance JavaScript [Haml](http://haml-lang.com) implementation for [nodejs](http://nodejs.org)
For a higher quality implementation you may want to look at my [Jade](http://jade-lang.com) template engine,
however the syntax is slightly different. Jade's engine may be back-ported to haml.js in the future.
[](https://travis-ci.org/visionmedia/haml.js)
## Installation
$ npm install hamljs
node> require('hamljs')
## Express
To use with [Express](http://expressjs.com) and the .haml extension, simply register the engine:
app.engine('.haml', require('hamljs').renderFile);
## About
Benchmarks rendering the same 21 line haml file located at _benchmarks/page.haml_,
shows that this library is nearly **65%** or **3 times** faster than haml-js.
Winner: haml.js
Compared with next highest (haml-js), it's:
65.39% faster
2.89 times as fast
0 order(s) of magnitude faster
Haml.js attempts to comply with the original [Haml](http://haml-lang.com/docs/yardoc/file.HAML_REFERENCE.html)
implementation as well as possible. There are no magic "plugins" like
found in other JavaScript haml implementations, for example the following
will work just fine:
- if (items)
%ul
- for (var i = 0; i < items.length; ++i)
%li= items[i]
Iteration is the one exception to these magical plugins,
since this is **ugly** in JavaScript, you may also:
- if (items)
%ul
- each item in items
%li= item
## Tags
%div text
html:
<div>text</div>
## Classes
%div.article.first
article text here
and here
html:
<div class="article first">
article text here and here
</div>
## Div Class Shortcut
.comment hey
html:
<div class="comment">hey</div>
## Div Id Shortcut
#article-1 foo
html:
<div id="article-1">foo</div>
## Combining Ids and Classes
You may chain id and classes in any order:
.article#first.summary content
html:
<div id="first" class="article summary">content</div>
## Attributes
%a{ href: 'http://google.com', title: 'Google It' } Google
html:
<a href="http://google.com" title="Google It">Google</a>
Attribute keys such as "for" are automatically quoted
by haml.js, so instead of:
%label{ 'for': 'something' }
you should:
%label{ for: 'something' }
which will render:
<label for="something"></label>
## Boolean Attributes
%input{ type: 'checkbox', checked: true }
html:
<input type="checkbox" checked="checked"/>
## Combining Attributes, Ids, and Classes
Wemay also contain id and classes before or after:
%a.button{ href: 'http://google.com', title: 'Google It' }.first Google
html:
<a href="http://google.com" title="Google It" class="button first">Google</a>
## Code
Code starting with a hyphen will be executed but
not buffered, where as code using the equals sign
will be buffered:
- a = 1
- b = 2
= a + b
html:
3
HTML buffered with equals sign will **always** be escaped:
= "<br/>"
html:
<br/>
To prevent escaping of HTML entities we can use _!=_:
!= "<br/>"
html:
<br/>
## Iteration
%ul
- each item in items
%li= item
html:
<ul>
<li>one</li>
<li>two</li>
<li>three</li>
</ul>
If you require the key or index of the object
or array during iteration simple append a comma
following another id:
%ul
- each item, index in items
%li= item + '(' + index + ')'
html:
<ul>
<li>one(0)</li>
<li>two(1)</li>
<li>three(2)</li>
</ul>
## Doctypes
Defaults to transitional:
!!!
html:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
Optionally pass a supported doctype name:
!!! strict
html:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
currently supported doctypes, which can be
extended simply by adding values to to _haml.doctypes_.
'5': '<!DOCTYPE html>',
'xml': '<?xml version="1.0" encoding="utf-8" ?>',
'default': '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">',
'strict': '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">',
'frameset': '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-frameset.dtd">',
'1.1': '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">',
'basic': '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML Basic 1.1//EN" "http://www.w3.org/TR/xhtml-basic/xhtml-basic11.dtd">',
'mobile': '<!DOCTYPE html PUBLIC "-//WAPFORUM//DTD XHTML Mobile 1.2//EN" "http://www.openmobilealliance.org/tech/DTD/xhtml-mobile12.dtd">'
## String interpolation
%div Hello #{world}
with locals:
{ world: "World!" }
html:
<div>Hello World!</div>
## :cdata
%script
:cdata
foo
html:
<script><![CDATA[
foo
]]></script>
## :javascript
%head
:javascript
if (foo)
if (bar)
alert('baz')
html:
<head>
<script type="javascript">
//<![CDATA[
if (foo)
if (bar)
alert('baz')
//]]>
</script>
</head>
## Extending Haml
### Adding Filters
var haml = require('hamljs')
haml.filters.my_filter = function(str) {
return doSomethingWith(str)
}
by registering the filter function _my_filter_ we can now
utilize it within our Haml templates as shown below:
%p
:my_filter
some text
here yay
whoop awesome
### Adding Doctypes
var haml = require('hamljs')
haml.doctypes.foo = '<!DOCTYPE ... >'
Will now allow you to:
!!! foo
