Le Less n'est plus compilé par le naigateur en JS, le serveur s'en occupe en PHP. Le JS n'est donc plus nécessaire au fonctionnement du générateur. Les favions sont également thémés, et dans les dimensions suivantes : 16², 32², 48², 64², 96², 128², 192², 256², 384² et 512².

# lessphp v0.5.0
|
|
### <http://leafo.net/lessphp>
|
|
|
|
`lessphp` is a compiler for LESS written in PHP. The documentation is great,
|
|
so check it out: <http://leafo.net/lessphp/docs/>.
|
|
|
|
Here's a quick tutorial:
|
|
|
|
### How to use in your PHP project
|
|
|
|
The only file required is `lessc.inc.php`, so copy that to your include directory.
|
|
|
|
The typical flow of **lessphp** is to create a new instance of `lessc`,
|
|
configure it how you like, then tell it to compile something using one built in
|
|
compile methods.
|
|
|
|
The `compile` method compiles a string of LESS code to CSS.
|
|
|
|
```php
|
|
<?php
|
|
require "lessc.inc.php";
|
|
|
|
$less = new lessc;
|
|
echo $less->compile(".block { padding: 3 + 4px }");
|
|
```
|
|
|
|
The `compileFile` method reads and compiles a file. It will either return the
|
|
result or write it to the path specified by an optional second argument.
|
|
|
|
```php
|
|
<?php
|
|
echo $less->compileFile("input.less");
|
|
```
|
|
|
|
The `checkedCompile` method is like `compileFile`, but it only compiles if the output
|
|
file doesn't exist or it's older than the input file:
|
|
|
|
```php
|
|
<?php
|
|
$less->checkedCompile("input.less", "output.css");
|
|
```
|
|
|
|
If there any problem compiling your code, an exception is thrown with a helpful message:
|
|
|
|
```php
|
|
<?php
|
|
try {
|
|
$less->compile("invalid LESS } {");
|
|
} catch (exception $e) {
|
|
echo "fatal error: " . $e->getMessage();
|
|
}
|
|
```
|
|
|
|
The `lessc` object can be configured through an assortment of instance methods.
|
|
Some possible configuration options include [changing the output format][1],
|
|
[setting variables from PHP][2], and [controlling the preservation of
|
|
comments][3], writing [custom functions][4] and much more. It's all described
|
|
in [the documentation][0].

### How to use from the 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:
|
|
|
|
$ plessc input.less > output.css
|
|
|
|
Using the -r flag, you can specify LESS code directly as an argument or, if
|
|
the argument is left off, from standard in:
|
|
|
|
$ plessc -r "my less code here"
|
|
|
|
Finally, by using the -w flag you can watch a specified input file and have it
|
|
compile as needed to the output file:
|
|
|
|
$ plessc -w input-file output-file
|
|
|
|
Errors from watch mode are written to standard out.
|
|
|
|
The -f flag sets the [output formatter][1]. For example, to compress the
|
|
output run this:
|
|
|
|
$ plessc -f=compressed myfile.less
|
|
|
|
For more help, run `plessc --help`
