tscc-compiler is an LALR(1) parser generator written in typescript, functions like a combination of flex and yacc, with some more useful features.
It uses Hanolee algorithm to generate the parse table, so that it can handle all the LR(1) grammars, including those cannot be handled by ordinary LALR(1) parsers, while the parse table is almost the same size as an LALR(1) parser does. It was designed to support more output languages. At present, it can generate parsers written in javascript and typescript.
