ESP-IDF Heapless JSON Stream Parser

This library provides a heapless JSON stream parser for ESP-IDF, allowing you to parse JSON streams without using dynamic memory allocation (heap).

Features

• Parse JSON streams without using heap memory
• Minimal memory footprint
• Simple integration into ESP-IDF projects
• Supports parsing JSON objects and arrays
• Handles parsing of JSON events from an event source stream

Usage

1. Include the library in your ESP-IDF project:

   git clone https://github.com/your-username/esp-idf-heapless-json-stream-parser.git

2. Include the library in your component makefile:

   COMPONENT_SRCDIRS += path/to/esp-idf-heapless-json-stream-parser

3. Initialize the JSON stream parser with a callback function to handle parsed JSON objects or arrays:

   #include "esp_heapless_json_stream_parser.h"
   
   json_stream_parser jparser([](std::string path, json_val_t value) {
       // Handle parsed JSON tokens here
   });

4. Initialize the event source stream parser with callbacks for events and data:

   #include "event_source_stream_parser.h"
   
   event_source_stream_parser eparser("event", "data", [](std::string event) -> on_evts_data_char_cb_t {
       // Handle event parsing and return a data callback
       return [&](char c) {
           jparser.parse(c); // Parse JSON data from the event
       };
   });

5. Parse JSON data as it becomes available in your stream input:

   // Example: Parsing JSON data from an event source stream
   size_t s = strlen(event_source_str);
   int i = 0;
   
   while (i < s) {
       eparser.parse(event_source_str[i]);
       i++;
   }

6. Cleanup the parser handle when finished:

   // No cleanup necessary for heapless JSON stream parser
