Introduction

ts-parsec is a parser combinator library prepared for typescript. By using this library, you are able to create parsers very quickly using just a few lines of code. It provides the following features:

• Tokenizer based on regular expressions. This tokenizer is designed for convenience. For some cases its performance may be unsatisfying. In this case, you could write your own tokenizer. It is very easy to plug your tokenizer into ts-parsec.
• Parser combinators.
• The ability to support recursive syntax.

You are recommended to learn EBNF before using this library.

Please read Getting Started for ramping up, or our document page for deeper understanding.

Following combinators will be released soon:

• A context sensitive apply combinator.

Context sensitive tokenizer is also comming.
