Base64

The base64 extractor decodes content encoded with the Base64 binary-to-text encoding scheme into the corresponding string value.

Predicate

When used as a predicate test with ~, and the referent target is a valid string and is base64 encoded, then the test succeeds.

Extraction

If predicate test succeeds, then the decoded base64 content it extracted and returned as a string literal.

Example

match { "test": "8J+MiiBzbm90IGJhZGdlcg==", "footle":ยท"bar" } of
case foo = %{test ~= base64|| } => foo
end;
