#rapidjson sounds great until you realize it's not had a release in almost 10 years at this point 😳
Well, at least #simdjson has had a better release record, the latest release being in December 2025 👀
Парсим XML и JSON на ассемблере
Отобрал для вас несколько крайне интересных, но малоизвестных проектов, реализующих работу с XML и JSON. Кроссплатформенных и без зависимостей. На чистом С и ассемблере.

#yyjson is an extremely fast #JSON #parser for #C.
yyjson parses and writes JSON data with very high throughput. yyjson uses parallel instructions on modern CPUs to greatly speed up the conversion from and to JSON. yyjson is very competetive with #simdjson, beating it in several tests. yyjson is written in #C89, and works on old hardware without #SIMD.

#simdjson is an extremely efficient #JSON #parser.
simdjson is a validating JSON parsing #library that uses SIMD instructions to parse input at extremely high speeds of GB/s on an average CPU. simdjson supports many reasonably recent 64 bit CPUs, including ARM. Input nodes are parsed into their optimal datatypes, allowing for full 64 bit integers and large floats.
