JSON Generator

A simple JSON (JavasScript Object Notation) generator with flushing capability. Details of JSON can be found at http://www.json.org/. The JSON strings generated can be validated using any standard JSON validator. Eg. https://jsonlint.com/

Files

• json_generator.c: Actual source file for the JSON generator with implementation of all APIS
• json_generator.h: Header file documenting and exposing all available APIs
• test.c: A test app which demonstrates the usage of the JSON generator
• Makefile: For generating the test executable

Usage

Include the C and H files in your project's build system and that should be enough. json_generator requires only standard library functions for compilation

Testing

• To compile the test executable, just execute "make".
• This will create "json_gen" binary.
• Running the binary should print the expected and generated JSON string on the terminal, and the test result

./json_gen 
Creating JSON string [may require Line wrap enabled on console]
Expected: {"first_bool":true,"first_int":30,"float_val":54.16430,"my_str":"new_name","null_obj":null,"arr":[["arr_string",false,45.12000,null,25,{"arr_obj_str":"sample"}]],"my_obj":{"only_val":5}}
Generated: {"first_bool":true,"first_int":30,"float_val":54.16430,"my_str":"new_name","null_obj":null,"arr":[["arr_string",false,45.12000,null,25,{"arr_obj_str":"sample"}]],"my_obj":{"only_val":5}}
Test Passed!

To cleanup the app, execute make clean
