import "std/json" as json;

JsonParser parses one value and reports validity through fields on the parser and result:

var parser = new json.JsonParser("{\"name\":\"Zap\"}");
var value = parser.parse();


if !value.valid {
    eprintln("invalid JSON");
    return 1;
}

Types

Section titled “Types”
  • JsonType identifies STRING, NUMBER, BOOL, NULLTYPE, or OBJECT.
  • JsonValue stores the tag, value fields, original object source, and valid.
  • JsonObject provides put, get, has, and size.
  • JsonParser exposes lower-level cursor and parsing methods in addition to parse.

The module is an early implementation, not a complete JSON codec. Object and string parsing work, while numbers, booleans, null, arrays, escaping, and serialization are not yet fully implemented. Check valid before using a parsed value.
