savedDataKeys

Built-ins

Canonical ID: storage.keys. Nederlands: bewaardeSleutels.

Returns a list of the app-private keys in ascending UTF-8 byte order. The order is deterministic and case-sensitive, not insertion order or locale-specific dictionary sorting. An empty store returns an empty list. Modifying the returned list does not rename or remove saved keys.

Signature

savedDataKeys()

Arguments

This call takes no arguments. Always write the parentheses.

Return value

List<Text>.

Example

# language: en
saveData("b", 2)
saveData("a", 1)
for key in savedDataKeys():
    say key, loadData(key, none)

In a fresh store, prints a 1 followed by b 2. Existing project data may add other keys.

Notes and common mistakes

Use the function name for your source language. Its canonical ID is a shared documentation label; you do not type that ID as a call. Giving your own variable or function the same name can hide the built-in. Supply the documented arguments and value types. Pliro reports mismatches when checking can detect them, or when the call runs.

Keys and saved text are not translated. Limits are 128 keys, 64 KiB per JSON value, 512 KiB per document, 32 nesting levels, and 8,192 values/nodes per value. Functions, nonfinite numbers, and Maps with non-Text keys cannot be stored. A usable portable project identity enables durable data; loose source uses temporary session storage. See the storage guide for E4014–E4017 and copy/identity rules.
