set

tip

The set operator is implied whenever a direct assignment is written. We recommend to use the implicit version. For example, use test = 42 instead of set test=42.

Assigns a value to a field, creating it if necessary.

field = expr
set field=expr...

Description

Assigns a value to a field, creating it if necessary. If the field does not exist, it is appended to the end. If the field name is a path such as foo.bar.baz, records for foo and bar will be created if they do not exist yet.

Examples

Append a new field:

from {a: 1, b: 2}
c = a + b
――――――――――――――――――
{a: 1, b: 2, c: 3}

Update an existing field:

from {a: 1, b: 2}
a = "Hello"
――――――――――――――――――
{a: "Hello", b: 2}
