- * Recursively compiles a block.
171
- *
172
- * A block is analogous to a CSS block in most cases. A single LESS document
173
- * is encapsulated in a block when parsed, but it does not have parent tags
174
- * so all of it's children appear on the root level when compiled.
175
- *
176
- * Blocks are made up of props and children.
177
- *
178
- * Props are property instructions, array tuples which describe an action
179
- * to be taken, eg. write a property, set a variable, mixin a block.
180
- *
181
- * The children of a block are just all the blocks that are defined within.
182
- * This is used to look up mixins when performing a mixin.
183
- *
184
- * Compiling the block involves pushing a fresh environment on the stack,
185
- * and iterating through the props, compiling each one.
186
- *
187
- * See lessc::compileProp()
188

2289

2290
- * This parser is most similar to a recursive descent parser. Single
2291
- * functions represent discrete grammatical rules for the language, and
2292
- * they are able to capture the text that represents those rules.
2293
- *
2294
- * Consider the function lessc::keyword(). (all parse functions are
2295
- * structured the same)
2296
- *
2297
- * The function takes a single reference argument. When calling the
2298
- * function it will attempt to match a keyword on the head of the buffer.
2299
- * If it is successful, it will place the keyword in the referenced
2300
- * argument, advance the position in the buffer, and return true. If it
2301
- * fails then it won't advance the buffer and it will return false.
2302
- *
2303
- * All of these parse functions are powered by lessc::match(), which behaves
2304
- * the same way, but takes a literal regular expression. Sometimes it is
2305
- * more convenient to use match instead of creating a new function.
2306
- *
2307
- * Because of the format of the functions, to parse an entire string of
2308
- * grammatical rules, you can chain them together using &&.
2309
- *
2310
- * But, if some of the rules in the chain succeed before one fails, then
2311
- * the buffer position will be left at an invalid state. In order to
2312
- * avoid this, lessc::seek() is used to remember and set buffer positions.
2313
- *
2314
- * Before parsing a chain, use $s = $this->seek() to remember the current
2315
- * position into $s. Then if a chain fails, use $this->seek($s) to
2316
- * go back where we started.
