Class Standards.JSON5.Validator

Description

An instance of this class can be used to validate a JSON5 object against a JSON5 schema.

Example

string schema_s = "{\n" +
       "  \"name\": \"SomeExample\",\n" +
       "  \"type\": \"object\",\n" +
       "  \"properties\": {\n" +
       "      \"name\": { \"type\": \"string\" },\n" +
       "      \"id\": {\n" +
       "          \"type\": \"integer\",\n" +
       "          \"minimum\": 0\n" +
       "      }\n" +
       "  }\n" +
       "}";
   string example_s = "{\n" +
       "  \"name\": \"An Example\",\n" +
       "  \"id\": 17\n" +
       "}";
   mixed schema = Standards.JSON5.decode(schema_s);
   mixed example = Standards.JSON5.decode(example_s);
   if (string error = Standards.JSON5.Validator(schema).validate(example))
      werror("Error: JSON5 string %O did not validate: %s\n", example_s, error);
   else
      write("JSON5 ok\n");

Note

This class validates only a subset of the JSON5 schema specification. Currently dependencies and references are not handled and regular expressions (for pattern properties) are limited to those that can be handled by Regexp.SimpleRegexp.

For more information of JSON5 schema look at http://json5-schema.org/documentation.html "The home of JSON5 Schema".
