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) … See more
In the early 1970s, Stephen C. Johnson, a computer scientist at Bell Labs / AT&T, developed Yacc because he wanted to insert an exclusive or operator into a B language compiler … See more
The input to Yacc is a grammar with snippets of C code (called "actions") attached to its rules. Its output is a shift-reduce parser in C that executes the C snippets associated with each rule as soon as the rule is recognized. Typical actions involve the … See more

Johnson developed Yacc because he wanted to insert an exclusive or operator into a B language compiler.1975A full description of Yacc was published.2008Stephen C. Johnson reflected that the contribution Yacc made to the spread of Unix and C is what he is proudest of.1970sYacc was influenced by and received its name in reference to TMG compiler-compiler.1970sYacc was originally written in the B programming language.1970sJohnson used Yacc to create the Portable C Compiler.1970sYacc was used on Unix to implement the Portable C Compiler, as well as parsers for such programming languages as FORTRAN 77, Ratfor, APL, bc, m4, etc.1970sAmong the languages that were first implemented with Yacc are AWK, C++, eqn and Pic.1970sBjarne Stroustrup attempted to use Yacc to create a formal specification of C++, but was defeated by C's syntax.1970sStroustrup did proceed to use Yacc to implement Cfront, the first implementation of C++.Yacc and similar programs (largely reimplementations) have been very popular. Yacc itself used to be available as the default parser … See more

- Grammar Specification:The input to YACC is a context-free grammar(usually in the Backus-Naur Form, BNF) that describes the syntax rules of the language it parses.
- Parser Generation:YACC translates the grammar into a C function that could perform an efficient parsing of input text according to such predefined rules.
- LALR(1) Parsing:This is a bottom-up parsing method that makes use of a single token looka…

- LALR(1) Parsing:This is a bottom-up parsing method that makes use of a single token lookahead in determining the next action of parsing.
- Semantic Actions:These are the grammar productions that are associated with an action; this enables the execution of code, usually in C, used in the construction of abstract syntax trees, the gener...
