/** |
| 20 |
* The scss compiler and parser. |
| 21 |
* |
| 22 |
* Converting SCSS to CSS is a three stage process. The incoming file is parsed |
| 23 |
* by `Parser` into a syntax tree, then it is compiled into another tree |
| 24 |
* representing the CSS structure by `Compiler`. The CSS tree is fed into a |
| 25 |
* formatter, like `Formatter` which then outputs CSS as a string. |
| 26 |
* |
| 27 |
* During the first compile, all values are *reduced*, which means that their |
| 28 |
* types are brought to the lowest form before being dump as strings. This |
| 29 |
* handles math equations, variable dereferences, and the like. |
| 30 |
* |
| 31 |
* The `compile` function of `Compiler` is the entry point. |
| 32 |
* |
| 33 |
* In summary: |
| 34 |
* |
| 35 |
* The `Compiler` class creates an instance of the parser, feeds it SCSS code, |
| 36 |
* then transforms the resulting tree to a CSS tree. This class also holds the |
| 37 |
* evaluation context, such as all available mixins and variables at any given |
| 38 |
* time. |
| 39 |
* |
| 40 |
* The `Parser` class is only concerned with parsing its input. |
| 41 |
* |
| 42 |
* The `Formatter` takes a CSS tree, and dumps it to a formatted string, |
| 43 |
* handling things like indentation. |
