(self: string): stringConverts a string to CONFIG_CASE (uppercase with underscores) for configuration keys.
When to use
Use to normalize configuration path segments into environment-variable-like
keys while preserving numeric word groups such as v2.
Details
Unlike constantCase, digit-letter boundaries are not split. For
example, "api-v2 xml" becomes "API_V2_XML".

Converts a string to uppercase.
Example (Converting strings to uppercase)
import { pipe, String } from "effect"
import * as assert from "node:assert"
assert.deepStrictEqual(pipe("a", String.toUpperCase), "A")
assert.deepStrictEqual(String.toUpperCase("hello"), "HELLO")
toUpperCase)
