devel/yyjson 0.12.0 OpenBSD

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.
