new_type

Creates a new Type. This function only creates a new type and does not allow you to specify any fields. With the set_type() function you can define the fields for the new type.

It is possible to use set_type directly without calling new_type first. However, sometimes you want to cross reference two types so you want both type to exists before calling set_type.

This function generates a change.

Function

new_type(type, [wrap_only, [hide_id]])

Arguments

Argument	Type	Description
type	string	Name of the Type to be created.
wrap_only	bool (optional)	When `true` the new type will be created with wrap-only mode enabled. Default is `false`.
hide_id	bool (optional)	When `true` the new type will be created with hide-id enabled. Default is `false`. See “hid” action on mod_type for more information.

If wrap-only mode is enabled, no typed thing of this type can be created nor can the type be used by other type. In wrap-only mode the only purpose of the type is to wrap other things.

Return value

The name of the newly created Type.

Example

This code shows a use case where new_type() is helpful:

new_type('A');
new_type('B');

set_type('A', {
    b: 'B?'
});

set_type('B', {
    a: 'A?'
});

// Return type information
types_info();
