7 Handling Context Dependencies
The Bison paradigm is to parse tokens first, then group them into larger syntactic units. In many languages, the meaning of a token is affected by its context. Although this violates the Bison paradigm, certain techniques (known as kludges) may enable you to write Bison parsers for such languages.
| 7.1 Semantic Info in Token Types | Token parsing can depend on the semantic context. | |
| 7.2 Lexical Tie-ins | Token parsing can depend on the syntactic context. | |
| 7.3 Lexical Tie-ins and Error Recovery | Lexical tie-ins have implications for how error recovery rules must be written. |
(Actually, “kludge” means any technique that gets its job done but is neither clean nor robust.)
