A new library.

[Joy-less]

Since hjson-cs has been abandoned, I created my own parser: HjsonSharp (MIT-license).

Aside from being actively maintained, it has a number of benefits over this existing library:

• Supports parsing HJSON, JSON5, JSONC and JSON
• Integrated with System.Text.Json
• Stream one JsonToken at a time without loading the entire document into memory
• Customisable feature switches for each non-JSON feature (want HJSON with hexadecimal numbers?)
• Compatible with UTF-8, UTF-16, UTF-32 and ASCII encodings
• Parse incomplete values, such as {"key": "val
• Uses the Result pattern to avoid the overhead of exceptions
• Supports escaped string newlines in single and double quoted strings, which were recently approved

Despite adding so many features, I think the source code is much more readable and structured than this library.

In terms of performance, the libraries are similar:

Method	Mean	Error	StdDev	Gen0	Gen1	Gen2	Allocated
LongStringHjsonCs	11,135,676.0 ns	25,272.15 ns	21,103.39 ns	1093.7500	1031.2500	734.3750	7828.64 KB

ShortIntegerHjsonCs	3,952.6 ns	18.41 ns	15.37 ns	0.4578	-	-	1.41 KB
ShortIntegerHjsonSharp	615.7 ns	3.08 ns	2.88 ns	0.3519	-	-	1.08 KB
PersonHjsonCs	2,440.2 ns	18.83 ns	17.61 ns	1.0376	-	-	3.19 KB
PersonHjsonSharp	4,658.1 ns	22.55 ns	21.09 ns	2.5177	-	-	7.73 KB

LongString is a 1,000,000 character string, ShortInteger is a 5 digit number, and Person is a simple object with five properties.

I'm happy to fix bugs or add new HJSON features if the specification changes. In my opinion, HJSON is far superior to JSON5.

Cool! I'll add link and badges on https://hjson.github.io/.
