VERSION

version 0.583

SYNOPSIS

  json-schema-eval \
    [ --specification_version|version <version> ] \
    [ --output_format <format> ] \
    [ --short_circuit ] \
    [ --max_traversal_depth <depth> ] \
    [ --validate_formats ] \
    [ --validate_content_schemas ] \
    [ --collect_annotations ] \
    [ --strict ] \
    [ --data <filename> ] \
    [ --schema <filename> ] \
    [ --validate-schema [filename] ]
    [ --add-schema <filename> ]

DESCRIPTION

A command-line interface to "evaluate" in JSON::Schema::Modern.

data.json contains:

  {"hello": 42.1}

schema.json contains:

  {"properties": {"hello": {"type": ["string", "integer"]}}}

Run:

  json-schema-eval --data data.json --schema schema.json

produces output:

  {
    "errors" : [
      {
        "error" : "got number, not one of string, integer",
        "instanceLocation" : "/hello",
        "keywordLocation" : "/properties/hello/type"
      },
      {
        "error" : "not all properties are valid",
        "instanceLocation" : "",
        "keywordLocation" : "/properties"
      }
    ],
    "valid" : false
  }

Or run:

  json-schema-eval --validate-schema schema.json

produces output:

  {
    "valid": true
  }

The exit value ($?) is 0 when the result is valid, 1 when it is invalid, and some other non-zero value if an exception occurred.

OPTIONS

All boolean and string options used as constructors to JSON::Schema::Modern are available.

Additionally, --data is used to provide the filename containing a json-encoded data instance, and --schema provides the filename containing a json-encoded schema.

If either or both of these are not provided, STDIN is used as input.

Only JSON-encoded data and schemas are supported at this time.

Alternatively, you can use --validate-schema and either provide a filename containing a json-encoded schema, or omit the argument to read a schema from STDIN. The schema will be evaluated against its meta-schema for the corresponding specification version.

Additional schemas, that you wish to use via the $ref keyword, can be added with --add-schema <filename>. The actual filename is insignificant: Make sure you use an $id keyword within that schema that matches the value you use in the $ref. This option can be used more than once.
