generate_json_schema()

Generate the JSON schema of RenderCV.

JSON schema is generated for the users to make it easier for them to write the input file. The JSON Schema of RenderCV is saved in the root directory of the repository and distributed to the users with the JSON Schema Store.

Returns:

  • dict –

    The JSON schema of RenderCV.
