unblend

undo the effects of blend

Synopsis

unblend(val any) -> any

Description

The unblend function converts a value val from a blended representation to a plain representation by

• replacing any value nested within val that is a union type with its underlying non-union value, and
• eliminating all optional fields from record types within val by replacing each optional field with value with its non-optional equivalent and eliminating entirely any optional fields without a value.

Examples

Remove union types

# spq
unblend(this)
# input
{a:1::(int64|string)}
{a:"foo"::(int64|string)}
# expected output
{a:1}
{a:"foo"}

Create then remove optional fields

# spq
blend | unblend(this)
# input
{x:1}
{x:2,y:3}
{x:4,z?:_::int64}
# expected output
{x:1}
{x:2,y:3}
{x:4}
