yyjson-0.12.0

A JSON library written in ANSI C. Features: - Fast: can read or write gigabytes of JSON data per second on modern CPUs. - Portable: complies with ANSI C (C89) for cross-platform compatibility. - Strict: complies with RFC 8259 JSON standard, ensuring strict number formats and UTF-8 validation. - Extendable: offers options to enable individual JSON5 features and custom 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 with JSON Pointer, JSON Patch, and JSON Merge Patch. - Developer-Friendly: easy integration with just 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.
