-[Less.php](http://lessphp.typesettercms.com)
-========
-
-This is the Wikimedia fork of a PHP port of the official LESS processor .
-

-* [Installation](#installation)
-* [Basic Use](#basic-use)
-* [Caching](#caching)
-* [Source Maps](#source-maps)
-* [Command Line](#command-line)

-
-About
----
-The code structure of less.php mirrors that of the official processor which helps us ensure compatibility and allows for easy maintenance.
-
-Please note, there are a few unsupported LESS features:
-
-- Evaluation of JavaScript expressions within back-ticks (for obvious reasons).
-- Definition of custom functions.
-
-
-Installation
----
-
-You can install the library with Composer or manually.
-
-#### Composer
-
-1. [Install Composer](https://getcomposer.org/download/)
-2. Run `composer require wikimedia/less.php`
-
-#### Manually From Release
-
-Step 1. [Download a release](https://github.com/wikimedia/less.php/releases) and upload the PHP files to your server.
-
-Step 2. Include the library:
-
-```php
-require_once '[path to less.php]/lib/Less/Autoloader.php';
-Less_Autoloader::register();
-```
-
-Basic Use
----
-
-#### Parsing Strings
-
-```php
-$parser = new Less_Parser();
-$parser->parse( '@color: #4D926F; #header { color: @color; } h2 { color: @color; }' );
-$css = $parser->getCss();
-```
-
-
-#### Parsing LESS Files
-The parseFile() function takes two arguments:
-
-1. The absolute path of the .less file to be parsed
-2. The url root to prepend to any relative image or @import urls in the .less file.
-
-```php
-$parser = new Less_Parser();
-$parser->parseFile( '/var/www/mysite/bootstrap.less', 'http://example.com/mysite/' );
-$css = $parser->getCss();
-```
-
-
-#### Handling Invalid LESS
-An exception will be thrown if the compiler encounters invalid LESS.
-
-```php
-try{
- $parser = new Less_Parser();
- $parser->parseFile( '/var/www/mysite/bootstrap.less', 'http://example.com/mysite/' );
- $css = $parser->getCss();
-}catch(Exception $e){
- $error_message = $e->getMessage();
-}
-```
-
-
-#### Parsing Multiple Sources
-less.php can parse multiple sources to generate a single CSS file.
-
-```php
-$parser = new Less_Parser();
-$parser->parseFile( '/var/www/mysite/bootstrap.less', '/mysite/' );
-$parser->parse( '@color: #4D926F; #header { color: @color; } h2 { color: @color; }' );
-$css = $parser->getCss();
-```
-
-#### Getting Info About The Parsed Files
-less.php can tell you which .less files were imported and parsed.
-
-```php
-$parser = new Less_Parser();
-$parser->parseFile( '/var/www/mysite/bootstrap.less', '/mysite/' );
-$css = $parser->getCss();
-$imported_files = $parser->allParsedFiles();
-```
-
-
-#### Compressing Output
-You can tell less.php to remove comments and whitespace to generate minimized CSS files.
-
-```php
-$options = array( 'compress'=>true );
-$parser = new Less_Parser( $options );
-$parser->parseFile( '/var/www/mysite/bootstrap.less', '/mysite/' );
-$css = $parser->getCss();
-```
-
-#### Getting Variables
-You can use the getVariables() method to get an all variables defined and
-their value in a php associative array. Note that LESS has to be previously
-compiled.
-```php
-$parser = new Less_Parser;
-$parser->parseFile( '/var/www/mysite/bootstrap.less');
-$css = $parser->getCss();
-$variables = $parser->getVariables();
-
-```
-
-
-
-#### Setting Variables
-You can use the ModifyVars() method to customize your CSS if you have variables stored in PHP associative arrays.
-
-```php
-$parser = new Less_Parser();
-$parser->parseFile( '/var/www/mysite/bootstrap.less', '/mysite/' );
-$parser->ModifyVars( array('font-size-base'=>'16px') );
-$css = $parser->getCss();
-```
-
-
-#### Import Directories
-By default, less.php will look for @imports in the directory of the file passed to parseFile().
-If you're using parse() or if @imports reside in different directories, you can tell less.php where to look.
-
-```php
-$directories = array( '/var/www/mysite/bootstrap/' => '/mysite/bootstrap/' );
-$parser = new Less_Parser();
-$parser->SetImportDirs( $directories );
-$parser->parseFile( '/var/www/mysite/theme.less', '/mysite/' );
-$css = $parser->getCss();
-```
-
-
-Caching
----
-Compiling LESS code into CSS is a time consuming process, caching your results is highly recommended.
-
-
-#### Caching CSS
-Use the Less_Cache class to save and reuse the results of compiled LESS files.
-This method will check the modified time and size of each LESS file (including imported files) and regenerate a new CSS file when changes are found.
-Note: When changes are found, this method will return a different file name for the new cached content.
-
-```php
-$less_files = array( '/var/www/mysite/bootstrap.less' => '/mysite/' );
-$options = array( 'cache_dir' => '/var/www/writable_folder' );
-$css_file_name = Less_Cache::Get( $less_files, $options );
-$compiled = file_get_contents( '/var/www/writable_folder/'.$css_file_name );
-```
-
-#### Caching CSS With Variables
-Passing options to Less_Cache::Get()
-
-```php
-$less_files = array( '/var/www/mysite/bootstrap.less' => '/mysite/' );
-$options = array( 'cache_dir' => '/var/www/writable_folder' );
-$variables = array( 'width' => '100px' );
-$css_file_name = Less_Cache::Get( $less_files, $options, $variables );
-$compiled = file_get_contents( '/var/www/writable_folder/'.$css_file_name );
-```
-
-
-#### Parser Caching
-less.php will save serialized parser data for each .less file if a writable folder is passed to the SetCacheDir() method.
-Note: This feature only caches intermediate parsing results to improve the performance of repeated CSS generation.
-Your application should cache any CSS generated by less.php.
-
-```php
-$options = array('cache_dir'=>'/var/www/writable_folder');
-$parser = new Less_Parser( $options );
-$parser->parseFile( '/var/www/mysite/bootstrap.less', '/mysite/' );
-$css = $parser->getCss();
-```
-
-You can specify the caching technique used by changing the ```cache_method``` option. Supported methods are:
-* ```php```: Creates valid PHP files which can be included without any changes (default method).
-* ```var_export```: Like "php", but using PHP's ```var_export()``` function without any optimizations.
- It's recommended to use "php" instead.
-* ```serialize```: Faster, but pretty memory-intense.
-* ```callback```: Use custom callback functions to implement your own caching method. Give the "cache_callback_get" and
- "cache_callback_set" options with callables (see PHP's ```call_user_func()``` and ```is_callable()``` functions). less.php
- will pass the parser object (class ```Less_Parser```), the path to the parsed .less file ("/some/path/to/file.less") and
- an identifier that will change every time the .less file is modified. The ```get``` callback must return the ruleset
- (an array with ```Less_Tree``` objects) provided as fourth parameter of the ```set``` callback. If something goes wrong,
- return ```NULL``` (cache doesn't exist) or ```FALSE```.
-
-
-
-Source Maps
----
-Less.php supports v3 sourcemaps
-
-#### Inline
-The sourcemap will be appended to the generated CSS file.
-
-```php
-$options = array( 'sourceMap' => true );
-$parser = new Less_Parser($options);
-$parser->parseFile( '/var/www/mysite/bootstrap.less', '/mysite/' );
-$css = $parser->getCss();
-```
-
-#### Saving to Map File
-
-```php
-$options = array(
- 'sourceMap' => true,
- 'sourceMapWriteTo' => '/var/www/mysite/writable_folder/filename.map',
- 'sourceMapURL' => '/mysite/writable_folder/filename.map',
- );
-$parser = new Less_Parser($options);
-$parser->parseFile( '/var/www/mysite/bootstrap.less', '/mysite/' );
-$css = $parser->getCss();
-```
-
-
-Command line
----
-An additional script has been included to use the compiler from the command line.
-In the simplest invocation, you specify an input file and the compiled CSS is written to standard out:
-
-```
-$ lessc input.less > output.css
-```
-
-By using the -w flag you can watch a specified input file and have it compile as needed to the output file:
-
-```
-$ lessc -w input.less output.css
-```
-
-Errors from watch mode are written to standard out.
-
-For more help, run `lessc --help`
-
-
-Integration with other projects
----
-
-#### Drupal 7
-
-This library can be used as drop-in replacement of lessphp to work with [Drupal 7 less module](https://drupal.org/project/less).
-
-How to install:
-
-1. [Download the less.php source code](https://github.com/wikimedia/less.php/archive/master.zip) and unzip it so that 'lessc.inc.php' is located at 'sites/all/libraries/lessphp/lessc.inc.php'.
-2. Download and install [Drupal 7 less module](https://drupal.org/project/less) as usual.
-3. That's it :)
-
-#### JBST WordPress theme
-
-JBST has a built-in LESS compiler based on lessphp. Customize your WordPress theme with LESS.
-
-How to use / install:
-
-1. [Download the latest release](https://github.com/bassjobsen/jamedo-bootstrap-start-theme) copy the files to your {wordpress/}wp-content/themes folder and activate it.
-2. Find the compiler under Appearance > LESS Compiler in your WordPress dashboard
-3. Enter your LESS code in the text area and press (re)compile
-
-Use the built-in compiler to:
-- set any [Bootstrap](http://getbootstrap.com/customize/) variable or use Bootstrap's mixins:
- -`@navbar-default-color: blue;`
- - create a custom button: `.btn-custom {
- .button-variant(white; red; blue);
-}`
-- set any built-in LESS variable: for example `@footer_bg_color: black;` sets the background color of the footer to black
-- use built-in mixins: - add a custom font: `.include-custom-font(@family: arial,@font-path, @path: @custom-font-dir, @weight: normal, @style: normal);`
-
-The compiler can also be downloaded as [plugin](http://wordpress.org/plugins/wp-less-to-css/)
-
-#### WordPress
-
-This simple plugin will simply make the library available to other plugins and themes and can be used as a dependency using the [TGM Library](http://tgmpluginactivation.com/)
-
-How to install:
-
-1. Install the plugin from your WordPress Dashboard: http://wordpress.org/plugins/lessphp/
-2. That's it :)
-
-
-Transitioning from Leafo/lessphp
----
-Projects looking for an easy transition from leafo/lessphp can use the lessc.inc.php adapter. To use, [Download the less.php source code](https://github.com/wikimedia/less.php/archive/master.zip) and unzip the files into your project so that the new 'lessc.inc.php' replaces the existing 'lessc.inc.php'.
-
-Note, the 'setPreserveComments' will no longer have any effect on the compiled LESS.
-
-Credits
----
-less.php was originally ported to PHP by [Matt Agar](https://github.com/agar) and then updated by [Martin Jantošovič](https://github.com/Mordred). This Wikimedia-maintained fork was split off from [Josh Schmidt's version](https://github.com/oyejorge/less.php).

- // Here in, the parsing rules/functions

- //
- // .class {
- // color: #fff;
- // border: 1px solid #000;
- // width: @w + 4px;
- // > .child {...}
- // }
- //
- // And here's what the parse tree might look like:
- //
- // Ruleset (Selector '.class', [
- // Rule ("color", Value ([Expression [Color #fff]]))
- // Rule ("border", Value ([Expression [Dimension 1px][Keyword "solid"][Color #000]]))
- // Rule ("width", Value ([Expression [Operation "+" [Variable "@w"][Dimension 4px]]]))

- // ])

- // In general, most rules will try to parse a token with the `$()` function, and if the return
- // value is truly, will return a new node, of the relevant type. Sometimes, we need to check
- // first, before parsing, that's when we use `peek()`.
- //
-
- //
- // The `primary` rule is the *entry* and *exit* point of the parser.
- // The rules here can appear at any level of the parse tree.
- //
- // The recursive nature of the grammar is an interplay between the `block`
- // rule, which represents `{ ... }`, the `ruleset` rule, and this `primary` rule,
- // as represented by this simplified grammar:
- //
- // primary → (ruleset | rule)+
- // ruleset → selector+ block
- // block → '{' primary '}'
