The only oddity in here is handling around `std::errc` because `0` is not part of the named enum values. As a workaround, treat the enum type as an int, and explicitly cast it when comparing it against `0`.
This more accurately matches the supported types for the JSON5 spec.

Thank you very much for working on that! I'll try to have a look in the next few days. (I wonder why the CI did not run for you PR, I'll have to investigate that.) |
`fast_float` allows for exponents containing floats, which are not allowed per the JSON5 spec. Constraining `fast_float` to a format which does not allow for these exponents results in other supported usages being rejected. To handle this, explicitly check by adding a new guard. `has_invalid_exponent` is a string scan which returns true if it finds a suffix on the string which looks like an invalid exponent.

I was able to confirm that the string I think it's now in good shape -- all tests pass -- and I hopefully have some more contributions to follow! |

First off, thanks for maintaining this library!
I'm trying to pitch in a bit to help and make sure things stay healthy.
It's my first time working with Cython, so I'll be a little slow to make changes.
This PR swaps the fast_double_parser for fast_float, per the deprecation warning cited in #83.
It all works cleanly except for a small number of tests regarding scientific notation.
I could use some input on how to push this over the finish line.
None of the
fast_floatbehaviors matches what the JSON5 tests expect, and the one which is labeledjson_or_infnanseems like the best fit for the spec in spirit.Right now, I'm seeing
pyjson5.loads(1e2.3)return100, which is definitely wrong.But I haven't yet figured out where the issue is. I would guess (from the above) that somehow it's truncating the data to
1e2.
