  4. Comparison of parser generators - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_parser...

    To do so technically would require a more sophisticated grammar, like a Chomsky Type 1 grammar, also termed a context-sensitive grammar. However, parser generators for context-free grammars often support the ability for user-written code to introduce limited amounts of context-sensitivity. (For example, upon encountering a variable declaration ...

    The Go programming language (GC) used Bison, but switched to a hand-written scanner and parser in version 1.5. [15] LilyPond requires Bison to generate its parser. [16] MySQL [17] GNU Octave uses a Bison-generated parser. [18] Perl 5 uses a Bison-generated parser starting in 5.10. [19] The PHP programming language (Zend Parser). PostgreSQL [20]

    en.wikipedia.org/wiki/Lexical_analysis

    Lexical tokenization is related to the type of tokenization used in large language models (LLMs) but with two differences. First, lexical tokenization is usually based on a lexical grammar, whereas LLM tokenizers are usually probability -based. Second, LLM tokenizers perform a second step that converts the tokens into numerical values.
