Lemon is a parser generator, maintained as part of the SQLite project, that generates a look-ahead LR parser (LALR parser) in the programming language C from an input context-free grammar. The generator is quite simple, implemented in one C source file with another file used as a template for output. Lexical analysis is performed externally.

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, user-written code could save the name and type of the variable into an external data structure, so that these could be checked against ...

Just had my edit trying to fix things undone - but the current state is inconsistent still. Carburetta is a C/C++ scannner *and* parser generator (so both), ranks first for "C scanner generator", ranks 4th for "C parser generator" (above bison and lemon, but below "PackCC"), and similar, but lower, for C++ and so on.
Tree-sitter uses a GLR parser, a type of LR parser. [ 13 ] [ 14 ] [ 12 ] Tree-sitter was originally developed by GitHub for use in the Atom text editor , where it was first released in 2018.
In computer science, a compiler-compiler or compiler generator is a programming tool that creates a parser, interpreter, or compiler from some form of formal description of a programming language and machine. The most common type of compiler-compiler is called a parser generator. [1] It handles only syntactic analysis.
