json.ne example throwing errors - Issue with moo?

I’m trying to run the example json.ne grammar on the following input:

["hello”]

And getting the following error:

Error: invalid syntax at line 1 col 2:

  ["hello"]
   ^
Unexpected "\”"

Am I missing something?

Just for context I’ve written a couple of simple grammars before without using moo or a custom lexer without any trouble. It seems from the nearley docs that there’s been a lot of change with the lexer implementation recently, so I’m thinking I may have missed something…

I’m running nearley 2.10.2 and moo 0.4.0

Duplicate of #247. Solution:

  var grammar = require('./json.js')
- var p = new nearley.Parser(grammar.ParserRules, grammar.ParserStart);
+ var p = new nearley.Parser(nearley.Grammar.fromCompiled(grammar));

  console.log(grammar.Lexer.has('number'))

Docs currently don’t mention fromCompiled() properly. We’re working on that. Check out this preview of updated docs.

Thank you for the repro code! You’re awesome.
