devel/yyjson 0.10.0 DragonFly

A high performance JSON library written in ANSI C. Features: * Fast: can read or write gigabytes per second JSON data on modern CPUs. * Portable: complies with ANSI C (C89) for cross-platform compatibility. * Strict: complies with RFC 8259 JSON standard, ensuring strict number format and UTF-8 validation. * Extendable: offers options to allow comments, trailing commas, NaN/Inf, and custom memory allocator. * Accuracy: can accurately read and write int64, uint64, and double numbers. * Flexible: supports unlimited JSON nesting levels, \u0000 characters, and non null-terminated strings. * Manipulation: supports querying and modifying using JSON Pointer, JSON Patch and JSON Merge Patch. * Developer-Friendly: easy integration with only one h and one c file.

Limitations: * An array or object is stored as a data structure such as linked list, which makes accessing elements by index or key slower than using an iterator. * Duplicate keys are allowed in an object, and the order of the keys is preserved. * JSON parsing result is immutable, requiring a mutable copy for modification.
