json_schemac is a JSON schema generator that gets JSON schema string from an original domain specific language.

This is the first example. This means simple object.

<object> { }

You can compile it as the following:

$ echo '<object> { }' | bin/json_schemac
{
  "type": "object"
}

You can add some properties to a schema with letter + or -. + means a required property and - means not required one.

<object> {
  + name <string>
  + price <number>
}

JSON schema you can get is the following:

{
  "type": "object",
  "properties": {
    "name": {
      "type": "string"
    },
    "price": {
      "type": "number"
    }
  },
  "required": [
    "name",
    "price"
  ]
}
