LibSassPHP

The sass extension (LibSassPHP) for PHP gives you an object-oriented system of parsing Sass from within your PHP applications. Under the hood it uses libsass to provide super speedy and compatible Sass parsing. And supports both synax (idebted and not - SASS, SCSS).

Supported and tested only on UNIX based servers that runs PHP5.x

What's Sass?

Sass is a CSS pre-processor language to add on exciting, new, awesome features to CSS. Sass was the first language of its kind and by far the most mature and up to date codebase.

Sass was originally created by Hampton Catlin (@hcatlin). The extension and continuing evolution of the language has all been the result of years of work by Natalie Weizenbaum (@nex4) and Chris Eppstein (@chriseppstein).

Installation

Currently, the only way to install the extension is manually:

$ git clone git://github.com/shlomohass/LibSassPHP

Remember to grab your submodules:

$ git submodule init
$ git submodule update

Or simply clone with

$ git clone --recursive git://github.com/shlomohass/LibSassPHP

...and compile it! I've written a little PHP script to do all the stuff you need to do:

$ php install.php

Run the tests:

$ make test

Finally, you can install with make:

$ make install

And then add it to your php.ini:

extension=sass.so

Usage

This extension has a very simple API:

$sass = new Sass();
$css = $sass->compile($source);

You can compile a file with compileFile():

$sass = new Sass();
$css = $sass->compileFile($source);

You can tell the compiler to use idented syntax (SASS syntax) by default it expect SCSS syntax:

$sass = new Sass();
$sass->setSyntax(true); //TRUE -> SASS, FALSE -> SCSS
$css = $sass->compile($source);

You can set the include path for the library to use:

$sass = new Sass();
$sass->setIncludePath('/tmp');
$css = $sass->compile($source);

You can set the style of your SASS file to suit your needs:

$sass = new Sass();
$sass->setStyle(Sass::STYLE_NESTED);

$sass = new Sass();
$sass->setStyle(Sass::STYLE_EXPANDED);

$sass = new Sass();
$sass->setStyle(Sass::STYLE_COMPACT);

$sass = new Sass();
$sass->setStyle(Sass::STYLE_COMPRESSED);

To generate source comments for a file inline - now in camelCase:

$sass = new Sass();
$sass->setComments(true);
$css = $sass->compileFile($source);

Aliases also exist so you can also use:

$css = $sass->compile_file($source);

You can set the source map file for the library to use:

$sass = new Sass();
$sass->setMapPath('/random.output.css.map');
$css = $sass->compileFile($source);

This needs to be done prior to getting the output of the map file. As it stands, both the output of the SASS file compile & the SASS source map file generation sequence are both strings.

The first array item will always be the compiled SASS file: $css[0]

The second array item will always be the source map output: $css[1]

If there's a problem, the extension will throw a SassException:

$sass = new Sass();

try
{
    $css = $sass->compile('dayrui3dui36di37');
}
catch (SassException $e)
{
    // $e->getMessage() - ERROR -- , line 1: invalid top-level expression

    $css = FALSE;
}

Potential / known issues

• The file_comments test will fail as it remains unable to figure out the path the test has been run in. It generates the output successfully
• Test may Fail for version check - don't worry some servers may parse the libsass version differently.

Forward planning

• HHVM Zend compatibility?
• Nginx extension?

• Refactor correctly for LibSass 3.2.4

Version 0.4.2

• CamelCase compile sequence

Version 0.4.1
