A Stylus parser for PHP

When I first saw Stylus I thought it was amazing and I implemented it into my nodejs application. When I started my next project, which was a PHP project, I liked Stylus so much that I wanted to implement it into my PHP project as well. Surprisingly, I couldn't find any Stylus parser for PHP. So I did as any developer would do and created my own. And I want to share it.

##Current Features

• Omit braces
• Omit colons
• Omit semi-colons
• Custom functions
• Importing other files
• '&' parent reference
• Mixins
• Interpolation
• Variables

##Using Stylus.php Using Stylus.php is really easy! Just include the following code:

require('Stylus.php');

$stylus = new Stylus();
$stylus->setReadDir('read');
$stylus->setWriteDir('write');
$stylus->setImportDir('import'); //if you import a file without setting this, it will import from the read directory
$stylus->parseFiles();

And that's all there is to it! Now a quick note about the parseFiles() function. It has one parameter called overwite which defaults to false. It is a flag indicating whether or not you want to overwrite your already parsed Stylus files.

This means that you could include this code on every page and you won't be parsing your Stylus files every time. But make sure that you set overwrite to true when you are developing or updating your Stylus files so the changes will be reflected in your site.

###Parse a Single File It is possible to only parse one file. Instead of calling parseFiles() you simply just call parseFile('my_styl'). parseFile()'s second parameter is the overwrite flag. If you wanted to parse a file on every page load but didn't want to parse every file you could use this to do so.

$stylus->parseFile('my_file', true);
$stylus->parseFiles();

##Assigning Variables Assigning variables is done the same way as in regular Stylus. But you now have the option of adding variables from PHP before parsing the stylus files by calling the assign function. Here is an example:

PHP

$stylus->assign('px_size', '30px');
$stylus->parseFiles();

Stylus

div
 font-size px_size

Yields

div {
    font-size: 30px;
}
