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).
