1 | # Emulate the is_numeric and validate_numeric functions
|
---|
2 | # The regex is what's currently used in is_numeric
|
---|
3 | # validate_numeric also allows range checking, which cannot be mapped to the string parsing inside the function.
|
---|
4 | # For full backwards compatibility, you will need to keep the validate_numeric call around to catch everything.
|
---|
5 | # To keep your development moving forward, you can also add a deprecation warning using the Integer type:
|
---|
6 | #
|
---|
7 | # ```class example($value) { validate_numeric($value, 10, 0) }```
|
---|
8 | #
|
---|
9 | # would turn into
|
---|
10 | #
|
---|
11 | # ```
|
---|
12 | # class example(Stdlib::Compat::Numeric $value) {
|
---|
13 | # validate_numeric($value, 10, 0)
|
---|
14 | # assert_type(Integer[0, 10], $value) |$expected, $actual| {
|
---|
15 | # warning("The 'value' parameter for the 'ntp' class has type ${actual}, but should be ${expected}.")
|
---|
16 | # }
|
---|
17 | # }
|

20 | # > Note that you need to use Variant[Integer[0, 10], Float[0, 10]] if you want to match both integers and floating point numbers.
|

21 | #
|
---|
22 | # This allows you to find all places where a consumers of your code call it with unexpected values.
