This repository contains the code for a recognizer and a negative sample generator for the language SQLite.

Both tools rely on an ANTLR parser, the parser found in src/gen was generated with the SQLite grammar found in the files grammar/SQLiteLexer.g4 and grammar/SQLiteParser.g4.

The negative sample generator is based on the word mutation method described by Raselimo, Taljaard and Fischer in their paper Breaking parsers: mutation-based generation of programs with guaranteed syntax errors [1].
