json-schema-codegen 0.0.3

Generates C++ code from JSON-Schema

JSON-Schema Codegen

This python library consumes JSON-Schema and generates C++ code. It generates structures to hold the values defined in the schema, restricting the values according to the schema. Each structure has JSON serialization and de-serialization methods.

Supported Schema Features

Schemas (and sub-schemas) that are boolean or schemas without type are not currently supported.

• type: string
  • minLength
  • maxLength
  • pattern
• type: string with enum
• type: integer
  • maximum
  • minimum
  • exclusiveMaximum
  • exclusiveMinimum
  • multipleOf
• type: number
  • maximum
  • minimum
  • exclusiveMaximum
  • exclusiveMinimum
  • multipleOf
• type: boolean
• type: null
• type: array
  • items
  • minItems
  • maxItems
• type: object
  • properties
  • required
• allOf
• anyOf
• oneOf

References

$ref references are supported for array items, object properties, allOf, anyOf, and oneOf. However, the caller must provide a class which translates the reference into a class name and namespace.

Installation

pip install json-schema-codegen

Usage

See example_usage.py for a more elaborate example.

import jsonschemacodegen.cpp as cpp

simpleResolver = cpp.SimpleResolver()
output_dir = "/tmp"

generator = cpp.GeneratorFromSchema(src_output_dir=output_dir,
    header_output_dir=output_dir, 
    resolver=simpleResolver,
    namespace=[],
    src_usings=[])

sampleSchema = {"type": "string"}

generator.Generate(sampleSchema, 'Example', 'example')
