Ox
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}.
