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]
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 – 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; GNU Debugger (gdb) – an advanced debugger; GNU m4 – macro processor
It is a computer program that generates lexical analyzers (also known as "scanners" or "lexers"). [ 3 ] [ 4 ] It is frequently used as the lex implementation together with Berkeley Yacc parser generator on BSD -derived operating systems (as both lex and yacc are part of POSIX ), [ 5 ] [ 6 ] [ 7 ] or together with GNU bison (a version of yacc ...
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]
Users invoke a language-specific driver program (gcc for C, g++ for C++, etc.), which interprets command arguments, calls the actual compiler, runs the assembler on the output, and then optionally runs the linker to produce a complete executable binary. Each of the language compilers is a separate program that reads source code and outputs ...

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 ...
