200 | - * functions represent discrete grammatical rules for the language, and |
|
201 | - * they are able to capture the text that represents those rules. |
|

|
203 | - * Consider the function Lessc::keyword(). (all parse functions are |
|
204 | - * structured the same) |
|
205 | - * |
|
206 | - * The function takes a single reference argument. When calling the |
|
207 | - * function it will attempt to match a keyword on the head of the buffer. |
|
208 | - * If it is successful, it will place the keyword in the referenced |
|
209 | - * argument, advance the position in the buffer, and return true. If it |
|
210 | - * fails then it won't advance the buffer and it will return false. |
|
211 | - * |
|
212 | - * All of these parse functions are powered by Lessc::match(), which behaves |
|
213 | - * the same way, but takes a literal regular expression. Sometimes it is |
|
214 | - * more convenient to use match instead of creating a new function. |
|
215 | - * |
|
216 | - * Because of the format of the functions, to parse an entire string of |
|
217 | - * grammatical rules, you can chain them together using &&. |
|
218 | - * |
|
219 | - * But, if some of the rules in the chain succeed before one fails, then |
|
220 | - * the buffer position will be left at an invalid state. In order to |
|
221 | - * avoid this, Lessc::seek() is used to remember and set buffer positions. |
|
222 | - * |
|
223 | - * Before parsing a chain, use $s = $this->seek() to remember the current |
|
224 | - * position into $s. Then if a chain fails, use $this->seek($s) to |
|
225 | - * go back where we started. |

196 | + * This function is called repeatedly until the entire document is |

197 | + * parsed. |
|
198 | + * |
|
199 | + * This parser is most similar to a recursive descent parser. Single |
|
200 | + * functions represent discrete grammatical rules for the language, and |
|
201 | + * they are able to capture the text that represents those rules. |
|
202 | + * |
|
203 | + * Consider the function Lessc::keyword(). (all parse functions are |
|
204 | + * structured the same) |
|
205 | + * |
|
206 | + * The function takes a single reference argument. When calling the |
|
207 | + * function it will attempt to match a keyword on the head of the buffer. |
|
208 | + * If it is successful, it will place the keyword in the referenced |
|
209 | + * argument, advance the position in the buffer, and return true. If it |
|
210 | + * fails then it won't advance the buffer and it will return false. |
|
211 | + * |
|
212 | + * All of these parse functions are powered by Lessc::match(), which behaves |
|
213 | + * the same way, but takes a literal regular expression. Sometimes it is |
|
214 | + * more convenient to use match instead of creating a new function. |
|
215 | + * |
|
216 | + * Because of the format of the functions, to parse an entire string of |
|
217 | + * grammatical rules, you can chain them together using &&. |
|
218 | + * |
|
219 | + * But, if some of the rules in the chain succeed before one fails, then |
|
220 | + * the buffer position will be left at an invalid state. In order to |
|
221 | + * avoid this, Lessc::seek() is used to remember and set buffer positions. |
|
222 | + * |
|
223 | + * Before parsing a chain, use $s = $this->seek() to remember the current |
|
224 | + * position into $s. Then if a chain fails, use $this->seek($s) to |
|
225 | + * go back where we started. |
