pretty print and ident config? about pyjson5

[Kijewski]

Pyjson5's parser does not preserve the comments or whitespaces. So the serializer is nearly identical to standard json.dump(s), except that pyjson5's output is HTML-safe and ASCII-only. If you need pretty printed data, then most likely you don't want either, because it hurts readability; and speed is also most likely quite unimportant, because it's not a lot of data to have to serialize. So I guess you could use pyjson5 for parsing, and json for stringifying.

I agree with sbant. Pretty printing is a desirable feature. After all, json5 emphasises on human friendliness, comments, etc. Using this parser a lot of it is lost.

However, the speed is amazing, nothing compares to it. And in some cases both are needed, e.g. real-time speed crucial app that needs to track config changes, which are potentially a manual user input.

dump(load(string)) == string, would be great to have as an option, even if a bit slower.

And another package is unbelievably slow.

Yaml is too slow, json is too raw, II was hoping to find a happy middle. Many are too complex, others at the risk of extinction, etc, etc... Difficult choice to be honest.

Benchmarked this package against a great lot and all looked great - happy middle, but this is a bit of a dealbreaker. For now, I will use abstracted orjson so I can swap later given I find a happy middle I was after. Maybe you know what sort of config parser sublime text uses? That one looked perfect tbh.

Adding benchmarks for reference:
