💥 Drop deprecated base64

[dubzzz]

Description

The arbitrary base64 has been marked for deprecation since version 3.22.0.

It is now being fully dropped.

If you still want to rely on something behaving this way we recommend you to use the following constructs:

function base64(): fc.Arbitrary<string> {
  return fc.constantFrom(...'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789+/');
}

Or even more accurate

function base64Mapper(v: number) {
  if (v < 26) return String.fromCharCode(v + 65); // A-Z
  if (v < 52) return String.fromCharCode(v + 97 - 26); // a-z
  if (v < 62) return String.fromCharCode(v + 48 - 52); // 0-9
  return v === 62 ? '+' : '/'; // 43, 47
}

function base64Unmapper(s: unknown) {
  if (typeof s !== 'string' || s.length !== 1) {
    throw new Error('Invalid entry');
  }
  const v = s.charCodeAt(0);
  if (v >= 65 && v <= 90) return v - 65; // A-Z
  if (v >= 97 && v <= 122) return v - 97 + 26; // a-z
  if (v >= 48 && v <= 57) return v - 48 + 52; // 0-9
  return v === 43 ? 62 : v === 47 ? 63 : -1; // +/
}

function base64() {
  return integer({ min: 0, max: 63 }).map(base64Mapper, base64Unmapper);
}
