This plugin enables the use of Coco/R inside Visual Studio 2015, 2017 and 2019.
It was upgraded from http://www.ssw.jku.at/coco/Tools/VSPlugin/.
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 (see below). The latest versions from the University of Linz are those for C#, Java and C++, which can be downloaded from this site. An older (non-reentrant) version of Coco/R for C# and Java can be obtained from here.
