Ox

language, tool A preprocessor, written by Kurt Bischoff of

Iowa State University, that extends and generalises the

syntax and semantics of Yacc, Lex, and C. Ox's

support of LALR1 grammars generalises yacc in the way that

attribute grammars generalise context-free grammars. It

augments Yacc and Lex specifications with definitions of

synthesised and inherited attributes written in C syntax.

Ox checks these specifications for consistency and

completeness, and generates a program that builds and

decorates attributed parse trees. Ox accepts a most general

class of attribute grammars. The user may specify

postdecoration traversals for easy ordering of side effects

such as code generation.

Latest version: G1.01, as of 1993-11-14.
