A Simple JSON parser written in C that supports jsonpath queries

Internally it uses jsmn (https://github.com/zserge/jsmn) for parsing the JSON string and jsmn-jsonpath (https://github.com/jakgra/jsmn-jsonpath) for the jsonpath queries support.

Usage

It is very simple. If this is the main.c file:

#include <s_json.h>
#include <string.h>
#include <stdio.h>

const char *json_str = "{ \"message\": \"Hello world.\", \"a_number\": 7 }";

int main() {
  s_json_t *json;

  json = s_json_init(json_str, strlen(json_str), NULL);
  printf(
         "%s I'm agent 00%d.\n",
         s_json_string(json, "$.message", 0, NULL),
         s_json_int(json, "$.a_number", 0, NULL)
        );

  return 0;
}

Build an run it:

git clone https://github.com/jakgra/simple_json_for_c.git
git clone https://github.com/zserge/jsmn.git && cd jsmn && git checkout v1.0.0 && cd ..
git clone https://github.com/jakgra/jsmn-jsonpath.git

./main

For error handling and all the available functions read the heavily documented but still short s_json.h file.
If you prefer man documentation execute: cd docs && doxygen and then man docs/man/man3/s_json.h.3
If you prefer pdf documentation execute: cd docs && doxygen && cd latex && make and then open docs/latex/refman.pdf
If you prefer html documentation execute: cd docs && doxygen and then open docs/html/index.html
