"Coco/R"@en . . . . "Coco/R is a compiler generator that takes an L-attributed Extended Backus\u2013Naur Form (EBNF) grammar of a source language and generates a scanner and a parser for that language.The scanner works as a deterministic finite automaton. It supports Unicode characters in UTF-8 encoding and can be made case-sensitive or case-insensitive. It can also recognize tokens based on their right-hand-side context."@en . .
