/**
|
| 14 |
-
* The scss compiler and parser.
|
| 15 |
-
*
|
| 16 |
-
* Converting SCSS to CSS is a three stage process. The incoming file is parsed
|
| 17 |
-
* by `scss_parser` into a syntax tree, then it is compiled into another tree
|
| 18 |
-
* representing the CSS structure by `scssc`. The CSS tree is fed into a
|
| 19 |
-
* formatter, like `scss_formatter` which then outputs CSS as a string.
|
| 20 |
-
*
|
| 21 |
-
* During the first compile, all values are *reduced*, which means that their
|
| 22 |
-
* types are brought to the lowest form before being dump as strings. This
|
| 23 |
-
* handles math equations, variable dereferences, and the like.
|
| 24 |
-
*
|
| 25 |
-
* The `parse` function of `scssc` is the entry point.
|
| 26 |
-
*
|
| 27 |
-
* In summary:
|
| 28 |
-
*
|
| 29 |
-
* The `scssc` class creates an instance of the parser, feeds it SCSS code,
|
| 30 |
-
* then transforms the resulting tree to a CSS tree. This class also holds the
|
| 31 |
-
* evaluation context, such as all available mixins and variables at any given
|
| 32 |
-
* time.
|
| 33 |
-
*
|
| 34 |
-
* The `scss_parser` class is only concerned with parsing its input.
|
| 35 |
-
*
|
| 36 |
-
* The `scss_formatter` takes a CSS tree, and dumps it to a formatted string,
|
| 37 |
-
* handling things like indentation.

-
* Recursively compiles a block.
|
| 395 |
-
*
|
| 396 |
-
* A block is analogous to a CSS block in most cases. A single SCSS document
|
| 397 |
-
* is encapsulated in a block when parsed, but it does not have parent tags
|
| 398 |
-
* so all of its children appear on the root level when compiled.
|
| 399 |
-
*
|
| 400 |
-
* Blocks are made up of selectors and children.
|
| 401 |
-
*
|
| 402 |
-
* The children of a block are just all the blocks that are defined within.
|
| 403 |
-
*
|
| 404 |
-
* Compiling the block involves pushing a fresh environment on the stack,
|
| 405 |
-
* and iterating through the props, compiling each one.
|
| 406 |
-
*
|
| 407 |
-
* @see scss::compileChild()
|
| 408 |
-
*

|
| 2758 |
-
* parsed.
|
| 2759 |
-
*
|
| 2760 |
-
* This parser is most similar to a recursive descent parser. Single
|
| 2761 |
-
* functions represent discrete grammatical rules for the language, and
|
| 2762 |
-
* they are able to capture the text that represents those rules.
|
| 2763 |
-
*
|
| 2764 |
-
* Consider the function scssc::keyword(). (All parse functions are
|
| 2765 |
-
* structured the same.)
|
| 2766 |
-
*
|
| 2767 |
-
* The function takes a single reference argument. When calling the
|
| 2768 |
-
* function it will attempt to match a keyword on the head of the buffer.
|
| 2769 |
-
* If it is successful, it will place the keyword in the referenced
|
| 2770 |
-
* argument, advance the position in the buffer, and return true. If it
|
| 2771 |
-
* fails then it won't advance the buffer and it will return false.
|
| 2772 |
-
*
|
| 2773 |
-
* All of these parse functions are powered by scssc::match(), which behaves
|
| 2774 |
-
* the same way, but takes a literal regular expression. Sometimes it is
|
| 2775 |
-
* more convenient to use match instead of creating a new function.
|
| 2776 |
-
*
|
| 2777 |
-
* Because of the format of the functions, to parse an entire string of
|
| 2778 |
-
* grammatical rules, you can chain them together using &&.
|
| 2779 |
-
*
|
| 2780 |
-
* But, if some of the rules in the chain succeed before one fails, then
|
| 2781 |
-
* the buffer position will be left at an invalid state. In order to
|
| 2782 |
-
* avoid this, scssc::seek() is used to remember and set buffer positions.
|
| 2783 |
-
*
|
| 2784 |
-
* Before parsing a chain, use $s = $this->seek() to remember the current
|
| 2785 |
-
* position into $s. Then if a chain fails, use $this->seek($s) to
|
| 2786 |
-
* go back where we started.

/**
|
| 26 |
+
* The scss compiler and parser.
|
| 27 |
+
*
|
| 28 |
+
* Converting SCSS to CSS is a three stage process. The incoming file is parsed
|
| 29 |
+
* by `Parser` into a syntax tree, then it is compiled into another tree
|
| 30 |
+
* representing the CSS structure by `Compiler`. The CSS tree is fed into a
|
| 31 |
+
* formatter, like `Formatter` which then outputs CSS as a string.
|
| 32 |
+
*
|
| 33 |
+
* During the first compile, all values are *reduced*, which means that their
|
| 34 |
+
* types are brought to the lowest form before being dump as strings. This
|
| 35 |
+
* handles math equations, variable dereferences, and the like.
|
| 36 |
+
*
|
| 37 |
+
* The `compile` function of `Compiler` is the entry point.
|
| 38 |
+
*
|
| 39 |
+
* In summary:
|
| 40 |
+
*
|
| 41 |
+
* The `Compiler` class creates an instance of the parser, feeds it SCSS code,
|
| 42 |
+
* then transforms the resulting tree to a CSS tree. This class also holds the
|
| 43 |
+
* evaluation context, such as all available mixins and variables at any given
|
| 44 |
+
* time.
|
| 45 |
+
*
|
| 46 |
+
* The `Parser` class is only concerned with parsing its input.
|
| 47 |
+
*
|
| 48 |
+
* The `Formatter` takes a CSS tree, and dumps it to a formatted string,
|
| 49 |
+
* handling things like indentation.

|
| 243 |
+
* parsed.
|
| 244 |
+
*
|
| 245 |
+
* This parser is most similar to a recursive descent parser. Single
|
| 246 |
+
* functions represent discrete grammatical rules for the language, and
|
| 247 |
+
* they are able to capture the text that represents those rules.
|
| 248 |
+
*
|
| 249 |
+
* Consider the function Compiler::keyword(). (All parse functions are
|
| 250 |
+
* structured the same.)
|
| 251 |
+
*
|
| 252 |
+
* The function takes a single reference argument. When calling the
|
| 253 |
+
* function it will attempt to match a keyword on the head of the buffer.
|
| 254 |
+
* If it is successful, it will place the keyword in the referenced
|
| 255 |
+
* argument, advance the position in the buffer, and return true. If it
|
| 256 |
+
* fails then it won't advance the buffer and it will return false.
|
| 257 |
+
*
|
| 258 |
+
* All of these parse functions are powered by Compiler::match(), which behaves
|
| 259 |
+
* the same way, but takes a literal regular expression. Sometimes it is
|
| 260 |
+
* more convenient to use match instead of creating a new function.
|
| 261 |
+
*
|
| 262 |
+
* Because of the format of the functions, to parse an entire string of
|
| 263 |
+
* grammatical rules, you can chain them together using &&.
|
| 264 |
+
*
|
| 265 |
+
* But, if some of the rules in the chain succeed before one fails, then
|
| 266 |
+
* the buffer position will be left at an invalid state. In order to
|
| 267 |
+
* avoid this, Compiler::seek() is used to remember and set buffer positions.
|
| 268 |
+
*
|
| 269 |
+
* Before parsing a chain, use $s = $this->seek() to remember the current
|
| 270 |
+
* position into $s. Then if a chain fails, use $this->seek($s) to
|
| 271 |
+
* go back where we started.
