Patterns

You can use regex array as mask (like text-mask-core). For easy usage you can use string patterns instead of regex array. Pattern characters are helper character for easily define pattern.

You can pass string, regex array or function as mask input. All following types are valid:

mask("12345", "###-##");
mask("12345", [/\d/, /\d/, /\d/, "-", /\d/, /\d/]);
mask("12345", (v:string) => { ... });

Predefined patterns is:

Character	RegExp	Description
"#"	/[0-9]/	match number
"A"	/[a-z]/i	match any alpha character (uppercase and lowercase)
"N"	/[a-z0-9]/i	match any alpha character and number (uppercase and lowercase)
"X"	/./	match any character
"!"	-	escape next character (use before pattern characters. e.g. !#)
