Introduction to bison

bison is a parser generator. It is to parsers what flex is to scanners. You provide the input of a grammar specification and it generates an LALR(1) parser

What are flex and bison?

Introducing Flex and Bison Flex and Bison are tools for building programs that handle structured input. They were originally tools for building compilers, but they have proven to be useful in many other areas.

What is a Flex scanner and bison parser?

Pure Scanners and Parsers A flex scanner and bison parser built in the usual way is not reentrant and can parse only one input stream at a time. That’s because both the scanner and the parser use static data structures to keep track of what they’re doing and to communicate with each other and with the calling program.

What is the difference between BNF and bison?

Most systems that run flex and bison use ASCII or extended 8-bit codes in the ISO-8859 series that include ASCII as a subset. bison A program that translates a dialect of BNF into LALR(1) or GLR parsers. BNF Backus-Naur Form; a method of represent- ing context-free grammars. It is commonly used to specify formal grammars of pro- gramming languages.

Can bison simulate actions embedded in a rule?

Even though bison’s parsing technique allows actions only at the end of a rule, bison can simulate actions embedded within a rule.
