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").
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]
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]
GNU Bison – Yacc-compatible parser generator program GNU C Library – GNU implementation of the standard C library Pages displaying short descriptions of redirect targets GNU Compiler Collection – Free and open-source compiler for various programming languages
The most established is lex, paired with the yacc parser generator, or rather some of their many reimplementations, like flex (often paired with GNU Bison). These generators are a form of domain-specific language , taking in a lexical specification – generally regular expressions with some markup – and emitting a lexer.
A lookahead LR parser (LALR) generator is a software tool that reads a context-free grammar (CFG) and creates an LALR parser which is capable of parsing files written in the context-free language defined by the CFG. LALR parsers are desirable because they are very fast and small in comparison to other types of parsers.
GNU Bison – parser generator intended to replace yacc GNU build system (autotools) – contains Autoconf , Automake , Autoheader, and Libtool GNU Compiler Collection – optimizing compiler for many programming languages , including C , C++ , Fortran , Ada , and Java
