The Compiler Generator Coco/R
Hanspeter Mössenböck, Markus Löberbauer, Albrecht Wöß, University of Linz
Coco/R is a compiler generator, which takes an attributed grammar of a source language and generates a scanner and a parser for this language. The scanner works as a deterministic finite automaton. The parser uses recursive descent. LL(1) conflicts can be resolved by a multi-symbol lookahead or by semantic checks. Thus the class of accepted grammars is LL(k) for an arbitrary k.
There are versions of Coco/R for different languages. This is the C# one made available from the Institut für Systemsoftware at the University of Linz.
