|
||||
by such Contributor that are necessarily infringed by their

|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the

||||
Work or Derivative Works thereof in any medium, with or without

|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must

||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed

||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||

|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|

|
||||
|
||||
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
|
||||

|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
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
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.

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).
