## Detailed Description

SCSS compiler written in PHP.

Copyright
  2012-2013 Leaf Corcoran

The scss compiler and parser. Converting SCSS to CSS is a three stage process. The incoming file is parsed by `scss_parser` into a syntax tree, then it is compiled into another tree representing the CSS structure by `scssc`. The CSS tree is fed into a formatter, like `scss_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 `scssc` is the entry point. In summary: The `scssc` class creates an instance of the parser, feeds it SCSS 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 `scss_parser` class is only concerned with parsing its input. The `scss_formatter` takes a CSS tree, and dumps it to a formatted string, handling things like indentation. SCSS compiler Leaf Corcoran leafo.nosp@m.t@gm.nosp@m.ail.c.nosp@m.om

scssc::compileBlock | ( |  | $block | ) |
| protected

Recursively compiles a block.

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

Blocks are made up of selectors and children.

The children of a block are just all the blocks that are defined within.

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