posAssertion doesn't work #511

Closed bjornkihlberg closed 2 months ago

bjornkihlberg commented 2 months ago

In the peggy documentation it is stated that image but this doesn't seem to work. Is the documentation out of date?

How to reproduce

  1. Install peggy 
    npm i -D peggy

  2. Code

    const ab_parser = peggy.generate('posAssertion = "a" &"b"')

ab_parser.parse("ab")

    Generates the error SyntaxError: Expected end of input but "b" found.

Never mind, I just realized that the examples have the match and rest patterns to make these work.
