				-
			
 
				-   You may add Your own copyright statement to Your modifications and
			
 
				-   may provide additional or different license terms and conditions
			
 
				-   for use, reproduction, or distribution of Your modifications, or

				-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

				-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).

				-	// The basic structure of the syntax tree generated is as follows:
			
 
				-	//
			
 
				-	//   Ruleset ->  Rule -> Value -> Expression -> Entity
			
 
				-	//
			
 
				-	// Here's some LESS code:
			
 
				-	//
			
 
				-	//	.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]]))

				-	//		 Ruleset (Selector [Element '>', '.child'], [...])
			
 
				-	//	 ])
			
 
				-	//
			
 
				-	//  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()`.

				-	// rule, which represents `{ ... }`, the `ruleset` rule, and this `primary` rule,
			
 
				-	// as represented by this simplified grammar:
			
 
				-	//
			
 
				-	//	 primary  →  (ruleset | rule)+
