Coco/S is a compiler generator that takes plain EBNF grammar files and features a SAX style call back API. It is written in Java and produces a Java Scanner (Lexer) and Parser for the language described by the input grammar.
Coco/S is a branch of the 2010/11 release of Coco/R for Java.
While Coco/R takes an attributed grammar file, Coco/S has a callback API. This has the advantage of a clean separation between grammar (EBNF) and Compiler/Interpreter.
Parsers for biological data based on scanner generators like Flex (C), Re2c(C), Jflex (Java) and Ifickle (Tcl). This scanner generators are providing easier maintainance, development and higher speed than hand written scanners. Scanner output is SQL.
