Download

To download json, execute the following command

$ git clone https://github.com/Jacob-C-Smith/json --recurse-submodules

Build

To build on UNIX like machines, execute the following commands in the same directory

$ cd json
$ cmake .
$ make

This will build the example program, and dynamic / shared libraries

To build json for Windows machines, open the base directory in Visual Studio, and build your desired target(s)

Example

NOTE: If you are running the tester program on Windows, you may have to copy example files to the Debug or Release directories. The example program parses the input file, and writes the parsed tokens to stdout. To run the example program, execute this command.

./json_example file1.json [file2.json ... fileN.json]

Example input

{
   "name"      : "Jacob Smith",
   "age"       : 20,
   "height"    : 1.775,
   "dog"       : {
       "name"  : "Eddie",
       "sex"   : "Male",
       "breed" : "Terrier"
   },
   "interests" : [
       "Computer science",
       "3D modeling",
       "Organic chemistry",
       "Mathematics",
       "Computer games",
       "Epistemology"
   ]
}

Tester

NOTE: If you are running the tester program on Windows, you may have to copy the serial test cases and parse test cases directories to the Debug or Release directories.

To run the tester program, execute this command after building

$ ./json_test
