Less.php API
========
## Basic use
#### Parse strings
```php
$parser = new Less_Parser();
$parser->parse( '@color: #36c; .link { color: @color; } a { color: @color; }' );
$css = $parser->getCss();
```
#### Parse files
The `parseFile()` function takes two parameters:
* The absolute path to a `.less` file.
* The base URL for any relative image or CSS references in the `.less` file,
typically the same directory that contains the `.less` file or a public equivalent.
```php
$parser = new Less_Parser();
$parser->parseFile( '/var/www/mysite/bootstrap.less', 'https://example.org/mysite/' );
$css = $parser->getCss();
```
#### Handle invalid syntax
An exception will be thrown if the compiler encounters invalid LESS.
```php
try{
$parser = new Less_Parser();
$parser->parseFile( '/var/www/mysite/bootstrap.less', 'https://example.org/mysite/' );
$css = $parser->getCss();
} catch (Exception $e) {
echo $e->getMessage();
}
```
#### Parse multiple inputs
Less.php can parse multiple input sources (e.g. files and/or strings) and generate a single CSS output.
```php
$parser = new Less_Parser();
$parser->parseFile( '/var/www/mysite/bootstrap.less', '/mysite/' );
$parser->parse( '@color: #36c; .link { color: @color; } a { color: @color; }' );
$css = $parser->getCss();
```
#### Metadata
Less.php keeps track of which `.less` files have been parsed, i.e. the input
file(s) and any direct and indirect imports.
```php
$parser = new Less_Parser();
$parser->parseFile( '/var/www/mysite/bootstrap.less', '/mysite/' );
$css = $parser->getCss();
$files = $parser->AllParsedFiles();
```
#### Compress output
You can tell Less.php to remove comments and whitespace to generate minified CSS.
```php
$options = [ 'compress' => true ];
$parser = new Less_Parser( $options );
$parser->parseFile( '/var/www/mysite/bootstrap.less', '/mysite/' );
$css = $parser->getCss();
```
#### Get variables
You can use the `getVariables()` method to get an all variables defined and
their value in an associative array. Note that the input must be compiled first
by calling `getCss()`.
```php
$parser = new Less_Parser;
$parser->parseFile( '/var/www/mysite/bootstrap.less');
$css = $parser->getCss();
$variables = $parser->getVariables();
```
#### Set variables
Use the `ModifyVars()` method to inject additional variables, i.e. custom values
computed or accessed from your PHP code.
```php
$parser = new Less_Parser();
$parser->parseFile( '/var/www/mysite/bootstrap.less', '/mysite/' );
$parser->ModifyVars( [ 'font-size-base' => '16px' ] );
$css = $parser->getCss();
```
#### Import directories
By default, Less.php will look for imported files in the directory of the file passed to `parseFile()`.
If you use `parse()`, or if need to enable additional import directories, you can specify these by
calling `SetImportDirs()`.
```php
$directories = [ '/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 can be a time-consuming process. It is recommended to cache your results.
#### Basic cache
Use the `Less_Cache` class to save and reuse the results of compiling LESS files.
This class will check the modified time and size of each LESS file (including imported files) and
either re-use or re-generate the CSS output accordingly.
The cache files are determinstically named, based on the full list of referenced LESS files and the metadata (file path, file mtime, file size) of each file. This means that each time a change is made, a different cache filename is used.
```php
$lessFiles = [ '/var/www/mysite/bootstrap.less' => '/mysite/' ];
$options = [ 'cache_dir' => '/var/www/writable_folder' ];
$cssOutputFile = Less_Cache::Get( $lessFiles, $options );
$css = file_get_contents( '/var/www/writable_folder/' . $cssOutputFile );
```
#### Caching with variables
Passing custom variables to `Less_Cache::Get()`:
```php
$lessFiles = [ '/var/www/mysite/bootstrap.less' => '/mysite/' ];
$options = [ 'cache_dir' => '/var/www/writable_folder' ];
$variables = [ 'width' => '100px' ];
$cssOutputFile = Less_Cache::Get( $lessFiles, $options, $variables );
$css = file_get_contents( '/var/www/writable_folder/' . $cssOutputFile );
```
#### Incremental caching
In addition to the whole-output caching described above, Less.php also has the ability to keep an internal cache which allows re-parses to be faster by effectively only re-compiling portions that have changed.
## Source maps
Less.php supports v3 sourcemaps.
#### Inline
The sourcemap will be appended to the generated CSS file.
```php
$options = [ 'sourceMap' => true ];
$parser = new Less_Parser($options);
$parser->parseFile( '/var/www/mysite/bootstrap.less', '/mysite/' );
$css = $parser->getCss();
```
#### Saving to map file
```php
$options = [
'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 Less.php compiler from the command line.
In its 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 information, run `lessc --help`

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only

Less.php
========
This is a PHP port of the [official LESS processor](https://lesscss.org).
## About
The code structure of Less.php mirrors that of upstream Less.js to ensure compatibility and help reduce maintenance. The port is currently compatible with Less.js 2.5.3. Please note that "inline JavaScript expressions" (via eval or backticks) are not supported.
* [API § Caching](./API.md#caching), Less.php includes a file-based cache.
* [API § Source maps](./API.md#source-maps), Less.php supports v3 sourcemaps.
* [API § Command line](./API.md#command-line), the `lessc` command includes a watch mode.
## Installation
You can install the library with Composer or standalone.
If you have [Composer](https://getcomposer.org/download/) installed:
1. Run `composer require wikimedia/less.php`
2. Use `Less_Parser` in your code.
Or standalone:
1. [Download Less.php](https://gerrit.wikimedia.org/g/mediawiki/libs/less.php/+archive/HEAD.tar.gz) and upload the PHP files to your server.
2. Include the library:
```php
require_once '[path to]/less.php/lib/Less/Autoloader.php';
Less_Autoloader::register();
```
3. Use `Less_Parser` in your code.
## Security
The LESS processor language is powerful and includes features that may read or embed arbitrary files that the web server has access to, and features that may be computationally exensive if misused.
In general you should treat LESS files as being in the same trust domain as other server-side executables, such as PHP code. In particular, it is not recommended to allow people that use your web service to provide arbitrary LESS code for server-side processing.
_See also [SECURITY](./SECURITY.md)._
## Who uses Less.php?
* **[Wikipedia](https://en.wikipedia.org/wiki/MediaWiki)** and the MediaWiki platform ([docs](https://www.mediawiki.org/wiki/ResourceLoader/Architecture#Resource:_Styles)).
* **[Matomo](https://en.wikipedia.org/wiki/Matomo_(software))** ([docs](https://devdocs.magento.com/guides/v2.4/frontend-dev-guide/css-topics/custom_preprocess.html)).
* **[Magento](https://en.wikipedia.org/wiki/Magento)** as part of Adobe Commerce ([docs](https://developer.matomo.org/guides/asset-pipeline#vanilla-javascript-css-and-less-files)).
* **[Icinga](https://en.wikipedia.org/wiki/Icinga)** in Icinga Web ([docs](https://github.com/Icinga/icingaweb2)).
* **[Shopware](https://de.wikipedia.org/wiki/Shopware)** ([docs](https://developers.shopware.com/designers-guide/less/)).
## Integrations
Less.php has been integrated with various other projects.
#### Transitioning from Leafo/lessphp
If you're looking to transition from the [Leafo/lessphp](https://github.com/leafo/lessphp) library, use the `lessc.inc.php` adapter file that comes with Less.php.
This allows Less.php to be a drop-in replacement for Leafo/lessphp.
[Download Less.php](https://gerrit.wikimedia.org/g/mediawiki/libs/less.php/+archive/HEAD.tar.gz), unzip the files into your project, and include its `lessc.inc.php` instead.
Note: The `setPreserveComments` option is ignored. Less.php already preserves CSS block comments by default, and removes LESS inline comments.
#### Drupal
Less.php can be used with [Drupal's less module](https://drupal.org/project/less) via the `lessc.inc.php` adapter. [Download Less.php](https://gerrit.wikimedia.org/g/mediawiki/libs/less.php/+archive/HEAD.tar.gz) and unzip it so that `lessc.inc.php` is located at `sites/all/libraries/lessphp/lessc.inc.php`, then install the Drupal less module as usual.
#### WordPress
* [wp_enqueue_less](https://github.com/Ed-ITSolutions/wp_enqueue_less) is a Composer package for use in WordPress themes and plugins. It provides a `wp_enqueue_less()` function to automatically manage caching and compilation on-demand, and loads the compressed CSS on the page.
* [JBST framework](https://github.com/bassjobsen/jamedo-bootstrap-start-theme) bundles a copy of Less.php.
* The [lessphp plugin](https://wordpress.org/plugins/lessphp/) bundles a copy of Less.php for use in other plugins or themes. This dependency can also be combined with the [TGM Library](http://tgmpluginactivation.com/).
## Credits
Less.php was originally ported to PHP in 2011 by [Matt Agar](https://github.com/agar) and then updated by [Martin Jantošovič](https://github.com/Mordred) in 2012. From 2013 to 2017, [Josh Schmidt](https://github.com/oyejorge) lead development of the library. Since 2019, the library is maintained by Wikimedia Foundation.
