json-inherited-attributes

Create json key-value pairs based on an inheritance model to help keep file contents relatively simple to maintain.

The parser will continue reading additions to a chain of inheritance until it encounters a dead end (where no more children objects are found to continue parsing) that is nested at least at the defined MINIMUM_DEPTH (default 1). In the example below, the sedan and hatchback trims are dead-ends and will thus end the parsing/inheritance chain.

The only key values that aren't overwritten are 'include' directives for the sake of referencing by a follow-up parser.

For help regarding command line arguments for the parser:

python3 parse.py -h

Example Usage

python3 parse.py test-input.json test-output.json

Takes the following input file, structured based on inheritance of attributes...

{
  "mazda": {
    "make": "mazda",
    "mazda-3": {
      "model": "mazda-3",
      "variants": ["base", "select", "preferred", "premium"],
      "trim": {
        "sedan": {},
        "hatchback": {
          "six-cylinder-variant": "premium"
        }
      }
    }
  }
}

And outputs a relatively flat json object:

{
  "mazda_mazda-3_trim_hatchback": {
    "make": "mazda",
    "model": "mazda-3",
    "six-cylinder-variant": "premium",
    "variants": [
      "base",
      "select",
      "preferred",
      "premium"
    ]
  },
  "mazda_mazda-3_trim_sedan": {
    "make": "mazda",
    "model": "mazda-3",
    "variants": [
      "base",
      "select",
      "preferred",
      "premium"
    ]
  }
}
