Refactor the NotEmpty rule
Since we have the ability to use `not` as a prefix, having rules that
validate negative behaviour makes them a bit inflexible, verbose, and
harder to understand.

This commit will refactor the `NotEmpty`, and rename it to `Falsy`. It
will no longer trim strings, because Blank does a much better job at it;
it only simulates the behaviour of PHP’s native `empty()` function.

Because `Falsy`, `Blank`, and `Undef` have similar behaviour, I created
a page to demonstrate the difference and show when the user should use
one or the other.

Min

  • Min(Rule $rule)

Validates the minimum value of the input against a given rule.

v::min(v::equals(10))->isValid([10, 20, 30]); // true

v::min(v::between('a', 'c'))->isValid(['b', 'd', 'f']); // true

v::min(v::greaterThan(new DateTime('yesterday')))
        ->isValid([new DateTime('today'), new DateTime('tomorrow')]); // true

v::min(v::lessThan(3))->isValid([4, 8, 12]); // false

Note

This rule uses Length with [GreaterThan][GreaterThan.md] internally. If an input has no items, the validation will fail.
