LPegLabel

Allows throwing custom labels (strings or integers) to distinguish specific errors from ordinary failures, enabling precise error identification as shown in the README examples like m.T'ErrId'.

Supports recovery rules that match when a label is thrown, letting parsers resume regular matching after handling errors, demonstrated in the 'Error Recovery' example with rule *Err*.

Automatically reports the farthest input position for ordinary failures, improving debugging by providing context on where parsing went wrong, as illustrated in the 'Reporting the farthest failure' example.

Offers concise syntax like %{l} and p^l through the relabel module, simplifying error handling patterns and making grammars more readable, as seen in the *relabel* syntax example.
