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.
