The following list is of projects which are known to "use" Bison in the looser sense, that they use free software development tools and distribute code which is intended to be fed into Bison or a Bison-compatible package. Bash shell uses a yacc grammar for parsing the command input. Bison's own grammar parser is generated by Bison. [11]
Flex (fast lexical analyzer generator) is a free and open-source software alternative to lex. [2] It is a computer program that generates lexical analyzers (also known as "scanners" or "lexers").

Profiling includes the time spent in the parser when the rule returns control to the parser. This allows for fine-tuning the performance of the generated scanners and parsers. Lexer rules that are hot spots , i.e. computationally expensive, are detected and can be optimized by the user in the lexer source code.
Berkeley Yacc (byacc) is a Unix parser generator designed to be compatible with Yacc.It was originally written by Robert Corbett and released in 1989. [3] Due to its liberal license and because it was faster than the AT&T Yacc, it quickly became the most popular version of Yacc. [4]
Lex is a computer program that generates lexical analyzers ("scanners" or "lexers"). [1] [2] It is commonly used with the yacc parser generator and is the standard lexical analyzer generator on many Unix and Unix-like systems. An equivalent tool is specified as part of the POSIX standard. [3]
Yacc (Yet Another Compiler-Compiler) is a computer program for the Unix operating system developed by Stephen C. Johnson.It is a lookahead left-to-right rightmost derivation (LALR) parser generator, generating a LALR parser (the part of a compiler that tries to make syntactic sense of the source code) based on a formal grammar, written in a notation similar to Backus–Naur form (BNF). [1]
[1] [2] It is specialized for use in text editors, as it supports incremental parsing for updating parse trees while code is edited in real time, [3] and provides a built-in S-expression query system for analyzing code. [4] Text editors which have official integrations with Tree-sitter include Atom, [5] GNU Emacs, [6] Neovim, [7] Lapce, [8] Zed ...
