Bring a grammar, get a parser. langlang turns Parsing Expression Grammars into fast, self-contained parsers with error recovery, automatic whitespace handling.

• simple syntax, readable, unambiguous, no shift/reduce conflicts
• Error labels and recovery rules produce useful trees from invalid input
• Automatic whitespace handling keeps grammars concise
• Generate parsers ahead-of-time or load grammars dynamically at runtime
• Ahead-of-time parsers are output with no external dependencies
