Method: Oj.default_options

Defined in:
ext/oj/oj.c

.default_options ⇒ Object

Returns the default load and dump options as a Hash. The options are

  • :indent [Fixnum|String|nil] number of spaces to indent each element in an JSON document, zero or nil is no newline between JSON elements, negative indicates no newline between top level JSON elements in a stream, a String indicates the string should be used for indentation

  • :circular [Boolean|nil] support circular references while dumping as well as shared references

  • :auto_define [Boolean|nil] automatically define classes if they do not exist

  • :symbol_keys [Boolean|nil] use symbols instead of strings for hash keys

  • :escape_mode [:newline|:json|:slash|:xss_safe|:ascii|:unicode_xss|nil] determines the characters to escape

  • :class_cache [Boolean|nil] cache classes for faster parsing (if dynamically modifying classes or reloading classes then don’t use this)

  • :mode [:object|:strict|:compat|:null|:custom|:rails|:wab] load and dump modes to use for JSON

  • :time_format [:unix|:unix_zone|:xmlschema|:ruby] time format when dumping

  • :bigdecimal_as_decimal [Boolean|nil] dump BigDecimal as a decimal number or as a String

  • :bigdecimal_load [:bigdecimal|:float|:auto|:fast|:ruby] load decimals as BigDecimal instead of as a Float. :auto pick the most precise for the number of digits. :float should be the same as ruby. :fast may require rounding but is must faster.

  • :compat_bigdecimal [true|false] load decimals as BigDecimal instead of as a Float when in compat or rails mode.

  • :create_id [String|nil] create id for json compatible object encoding, default is ‘json_class’

  • :create_additions [Boolean|nil] if true allow creation of instances using create_id on load.

  • :second_precision [Fixnum|nil] number of digits after the decimal when dumping the seconds portion of time

  • :float_precision [Fixnum|nil] number of digits of precision when dumping floats, 0 indicates use Ruby

  • :float_format [String] the C printf format string for printing floats. Default follows the float_precision and will be changed if float_precision is changed. The string can be no more than 6 bytes.

  • :use_to_json [Boolean|nil] call to_json() methods on dump, default is false

  • :use_as_json [Boolean|nil] call as_json() methods on dump, default is false

  • :use_raw_json [Boolean|nil] call raw_json() methods on dump, default is false

  • :nilnil [Boolean|nil] if true a nil input to load will return nil and not raise an Exception

  • :empty_string [Boolean|nil] if true an empty input will not raise an Exception

  • :allow_gc [Boolean|nil] allow or prohibit GC during parsing, default is true (allow)

  • :quirks_mode [true,|false|nil] Allow single JSON values instead of documents, default is true (allow)

  • :allow_invalid_unicode [true,|false|nil] Allow invalid unicode, default is false (don’t allow)

  • :allow_nan [true,|false|nil] Allow Nan, Infinity, and -Infinity to be parsed, default is true (allow)

  • :indent_str [String|nil] String to use for indentation, overriding the indent option is not nil

  • :space [String|nil] String to use for the space after the colon in JSON object fields

  • :space_before [String|nil] String to use before the colon separator in JSON object fields

  • :object_nl [String|nil] String to use after a JSON object field value

  • :array_nl [String|nil] String to use after a JSON array value

  • :nan [:null|:huge|:word|:raise|:auto] how to dump Infinity and NaN. :null places a null, :huge places a huge number, :word places Infinity or NaN, :raise raises and exception, :auto uses default for each mode.

  • :hash_class [Class|nil] Class to use instead of Hash on load, :object_class can also be used

  • :array_class [Class|nil] Class to use instead of Array on load

  • :omit_nil [true|false] if true Hash and Object attributes with nil values are omitted

  • :omit_null_byte [true|false] if true null bytes in strings will be omitted when dumping

  • :ignore [nil|Array] either nil or an Array of classes to ignore when dumping

  • :ignore_under [Boolean] if true then attributes that start with _ are ignored when dumping in object or custom mode.

  • :cache_keys [Boolean] if true then hash keys are cached if less than 35 bytes.

  • :cache_str [Fixnum] maximum string value length to cache (strings less than this are cached)

  • :integer_range [Range] Dump integers outside range as strings.

  • :trace [true,|false] Trace all load and dump calls, default is false (trace is off)

  • :safe [true,|false] Safe mimic breaks JSON mimic to be safer, default is false (safe is off)

Return [Hash] all current option settings.
