v prefix is not part of semver

[jelhan]

'v1.0.0'.match(semverRegex()) returns ['v1.0.0'] but should be ['1.0.0'].

node-semver handles the v fine. I don't really see a good way around this, as if you look at the regex itself, you see that it needs to not match foo1.0.0, but match v1.0.0 and 1.0.0. PR welcome if you have a solution for this.

Following spec 2.0.0 I didn't see why a v prefix should be treated differently than any other prefix. I guess semverRegex.test('foo1.0.0') should be true if semverRegex.test('v1.0.0') returns true. In both cases .match(semverRegex()) should return ['1.0.0'].

v is a common convention for indicating something is a version. You can see it in most git tags on GitHub.

I do agree the correct way would be to return the matched version without the v prefix, but the prefix is so common we can't ignore versions with it, and foo1.0.0 should definitely not be matched. Happy to consider a solution that satisfies these requirements :)

I have taken another path for my feature I needed this. Haven't any idea myself how this one could be handled just by RegExp.

[sindresorhus]

@jelhan I don't know what you need it for, but you might find find-versions useful.

semver package clean() method remove all equal and v characters on its regexp.
