compat.yyjson
#includeFastest C JSON library with SIMD — ANSI C, zero dependencies
#include "yyjson.h"
mcpp add compat.yyjson@0.13.0
Usage
From this repository's own test project — built and run by CI, not written for the website.
// Smoke test — verify compat.yyjson builds, links, and works
#include "yyjson.h"
import std;
int main() {
const char* json = R"({"name":"mcpp","version":"0.12.0"})";
yyjson_doc* doc = yyjson_read(json, strlen(json), 0);
if (!doc) return 1;
auto* root = yyjson_doc_get_root(doc);
auto* name = yyjson_obj_get(root, "name");
if (!name || std::string_view{yyjson_get_str(name)} != "mcpp") return 2;
std::println("compat.yyjson smoke test: ok");
yyjson_doc_free(doc);
return 0;
