GPL VERSION 3

Please refer to http://www.gnu.org/licenses/gpl-3.0.html for the full text of the GPL version 3 The LESS compiler and parser.

Converting LESS to CSS is a three stage process. The incoming file is parsed by lessc_parser into a syntax tree, then it is compiled into another tree representing the CSS structure by lessc. The CSS tree is fed into a formatter, like lessc_formatter which then outputs CSS as a string.

During the first compile, all values are reduced, which means that their types are brought to the lowest form before being dump as strings. This handles math equations, variable dereferences, and the like.

The parse function of lessc is the entry point.

In summary:

The lessc class creates an instance of the parser, feeds it LESS code, then transforms the resulting tree to a CSS tree. This class also holds the evaluation context, such as all available mixins and variables at any given time.

The lessc_parser class is only concerned with parsing its input.

The lessc_formatter takes a CSS tree, and dumps it to a formatted string, handling things like indentation.

◆ cachedCompile()

lessc::cachedCompile	(	$in,
		$force = `false`
	)

Execute lessphp on a .less file or a lessphp cache structure.

The lessphp cache structure contains information about a specific less file having been parsed. It can be used as a hint for future calls to determine whether or not a rebuild is required.

The cache structure contains two important keys that may be used externally:

compiled: The final compiled CSS updated: The time (in seconds) the CSS was last compiled

The cache structure is a plain-ol' PHP associative array and can be serialized and unserialized without a hitch.

Parameters

mixed	$in	Input
bool	$force	Force rebuild?

Returns: array lessphp cache structure

◆ compileBlock()

lessc::compileBlock ( $block )

protected

Recursively compiles a block.

A block is analogous to a CSS block in most cases. A single LESS document is encapsulated in a block when parsed, but it does not have parent tags so all of it's children appear on the root level when compiled.

Blocks are made up of props and children.

Props are property instructions, array tuples which describe an action to be taken, eg. write a property, set a variable, mixin a block.

The children of a block are just all the blocks that are defined within. This is used to look up mixins when performing a mixin.

Compiling the block involves pushing a fresh environment on the stack, and iterating through the props, compiling each one.
