资源说明：HAML-like template engine for PHP 5.3 & Symfony2
# Jade - template compiler for PHP5.3
*Jade* is a high performance template compiler heavily influenced by [Haml](http://haml-lang.com)
and implemented for PHP 5.3.
## Features
- high performance parser
- great readability
- contextual error reporting at compile & run time
- html 5 mode (using the _!!! 5_ doctype)
- combine dynamic and static tag classes
- no tag prefix
- clear & beautiful HTML output
- filters
- :php
- :cdata
- :css
- :javascript
- you even can write & add own filters throught API
- [TextMate Bundle](http://github.com/miksago/jade-tmbundle)
- [VIM Plugin](http://github.com/vim-scripts/jade.vim.git)
## Public API
$dumper = new PHPDumper();
$dumper->registerVisitor('tag', new AutotagsVisitor());
$dumper->registerFilter('javascript', new JavaScriptFilter());
$dumper->registerFilter('cdata', new CDATAFilter());
$dumper->registerFilter('php', new PHPFilter());
$dumper->registerFilter('style', new CSSFilter());
// Initialize parser & Jade
$parser = new Parser(new Lexer());
$jade = new Jade($parser, $dumper);
// Parse a template (both string & file containers)
echo $jade->render($template);
## Syntax
### Line Endings
**CRLF** and **CR** are converted to **LF** before parsing.
### Indentation
Jade is indentation based, however currently only supports a _2 space_ indent.
### Tags
A tag is simply a leading word:
html
for example is converted to ``
tags can also have ids:
div#container
which would render ``
how about some classes?
div.user-details
renders ``
multiple classes? _and_ an id? sure:
div#foo.bar.baz
renders ``
div div div sure is annoying, how about:
#foo
.bar
which is syntactic sugar for what we have already been doing, and outputs:
jade.php has a feature, called "autotags". It's just snippets for tags. Autotags will expand to basic tags with custom attributes. For example:
input:text
will expand to `` & it's the same as `input( type="text" )`, but shorter.
Another examples:
input:submit( value="Send" )
will become ``.
You can even add you own autotags with:
$parser->setAutotag('input:progress', 'input', array('type'=>'text', class=>'progress-bar'));
that will expands to ``.
It also supports new HTML5 tags (`input:email` => ``).
### Tag Text
Simply place some content after the tag:
p wahoo!
renders `wahoo!
`.
well cool, but how about large bodies of text:
p
| foo bar baz
| rawr rawr
| super cool
| go Jade go
renders `foo bar baz rawr.....
`
Actually want `` for some reason? Use `{{}}` instead:
p {{$something}}
now we have ``
### Nesting
ul
li one
li two
li three
### Attributes
Jade currently supports '(' and ')' as attribute delimiters.
a(href='/login', title='View login page') Login
Alternatively we may use the colon to separate pairs:
a(href: '/login', title: 'View login page') Login
Boolean attributes are also supported:
input(type="checkbox", checked)
Boolean attributes with code will only output the attribute when `true`:
input(type="checkbox", checked: someValue)
Note: Leading / trailing whitespace is _ignore_ for attr pairs.
### Doctypes
To add a doctype simply use `!!!` followed by an optional value:
!!!
Will output the _transitional_ doctype, however:
!!! 5
Will output html 5's doctype. Below are the doctypes
defined by default, which can easily be extended:
$doctypes = array(
'5' => '',
'xml' => '',
'default' => '',
'transitional' => '',
'strict' => '',
'frameset' => '',
'1.1' => '',
'basic' => '',
'mobile' => ''
);
## Comments
### Jade Comments
Jade supports sharp comments (`//- COMMENT`). So jade block:
//- JADE
- $foo = "
