C語言的 JSON 解析包 libjson

libjson 是一個完全兼容 JSON 規范的 json 格式數據的 C 語言解析包。

以下是libjson:

• Interruptible parser: get the JSON data to the parser any way you want; by appending char by char, or string chunks, the input reading is completely left to the caller.
• No object model integrated: easy integration with any model by the means of a simple callback.
• Small codebase: handcoded parser and efficient factorisation make the code smalls.
• Fast: use efficient code, and small parsing tables to not do any extra work and remains as fast and efficient as possible.
• Full JSON support: tested through a small and precise testsuite.
• No native conversion: callback only string of data and leave the actual representation of data to the caller
• Supports putting limits on nesting level. security against DoS over very deep data.
• Supports putting limits on data (string/int/float) size. security against DoS over very large data object.
• Optionally support YAML/python comments and C comments.
• Supports projects-specific allocation functions to integrate completely with projects
• jsonlint utility provided with the library to verify, or reformat json stream. also useful as example on how to use the library.

示例代碼：

int ret;
json_parser parser;

ret = json_parser_init(&parser, NULL, my_callback, my_callback_data);
if (ret) {
    fprintf(stderr, "something wrong happened during init\n");
    return ret;
}
