Incorrect YAML syntax highlighting for version numbers with multiple periods

[rpatrick00]

Given a YAML file that looks like this:

topology:
    Name: todo_domain
    DomainVersion: 12.2.1.4.0

The DomainVersion field value is highlighted as a numeric constant instead of a string.

I tested the following regular expression using one of the online regex testers and it is not excluding numbers with multiple dots in it.

{
    token : "constant.numeric", // float
    regex : /(\b|[+\-\.])[\d_]+(?:(?:\.[\d_]*)?(?:[eE][+\-]?[\d_]+)?)(?=[^\d-\w]|$)/
}

I would prefer numbers with multiple dots to be seen as numeric instead of string.

@AlexanderMisel But numbers can have, at most, only one decimal point. While your preference may be to highlight these as a numeric, it is not technically correct to do so. If you try to convert such a string into a number in any programming language, it will fail.

You are right. If I were to write a lexer for parsing, I would try to make it as accurate as I can.
