Example grammar that parses JSON like JSON.parse?

[fabiospampinato]

Hello, I'd like to benchmark my little parser generator against Chevrotain, but I can't find a first-party grammar for it that parses JSON. I see there's this one, but it parses JSON to a CST, in order to compare it against my grammar it would have to parse JSON in the JSON.parsesense. Is a first-party grammar like that available?

Thanks.

You can find the performance section of other peg-like parsers in chevrotain's gh-pages branch.

You will need to take this grammar:

• https://github.com/Chevrotain/chevrotain/blob/gh-pages/performance/jsonParsers/chevrotain/chevrotainEmbeddedParser.mjs

and modify it to include the actions to bulid the JSON object.
