GOLD is a parsing system targeting multiple programming language.

GOLD can be found on :

The GOLD Parsing System Homepage

  • LALR to analyze syntax
  • DFA to identify different lexical units.

The GOLD system consists of :

  • The Builder analyzes the syntax of a language (specified as a grammar) and construct LALR and DFA tables.
  • The Compiled Grammar Table file definition stores table information generated by the Builder and serves as an intermediary between the Builder and the Engine.
  • The Engine, written for a target programming language and/or development platform Engine implements the LALR and DFA algorithms.

GOLD logically separates the development of the LALR and DFA parse tables from the algorithms that use them. As a result, grammars are completely independent of any implementation language or platform.

The GOLD Meta-Language is used to define a grammar:
