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.
