Hot to create a mask for numbers and Uppercase letters

[ferulisses]

In the examples, we can choose between "AAA" and that will accept typing in upper or lowercase and convert to uppercase.

But there is no such functionality if we are using "XXX", it will accept upper and lowercase characters.

As a suggestion, you could create "YYY" and "yyy" that will accept numbers and the respective uppercase or lowercase characters and have the same functionality as "AAA" and "aaa"

Examples of data are the new Mercosul car plates:
ABC-1234
ABC-1A34
ABC-12A4

I could figure out a way to support these using array:
['AAA-XXXX','AAA-XAXX','AAA-XXAX']

But for another application, I will need to support combinations of letters and numbers to type a serial code, examples:
ABCD-1234-WXYZ-5678
2345-BCDE-8765-ZYXW
A1B2-C3D4-E5F6-G7H8

The array for these combinations will be too big.

You can define your own regular expression
<the-mask mask="FFFFFF" :tokens="hexTokens" />
then in your script somewhere:

hexTokens: {
  F: {
    pattern: /[0-9A-Z]/,
    transform: v => v.toLocaleUpperCase()
  }
}

the regular expression A-Z will capture all capital letters and 0-9 wil capture all integers.
the
transform: v => v.toLocaleUpperCase() line will automatically convert input to capitalize
