Tag name rules

[sadorowo]

Feature Description

Idea

I think it would be great if Gitea had something like tag name rules. This would be the exact opposite of tag protection - repository administrators will be able to set up, for example, a regular expression or glob, to match tags.

If tag name wouldn't match, it will be rejected.

Why not use tag protection?

Someone will say:
We have already tag protection. Assume you have regular expression like this:

^\Av\d+\.\d+\.\d+\z$

Just use negative lookahead, and slightly modify your regex...

^(?!\Av\d+\.\d+\.\d+\z).*$

...and everything will be fine - no need to create another feature!

Unfortunately this is not possible, because we can't use negative lookahead - Go regexp uses RE2 syntax, not PCRE.

Conclusion

• we would be sure that the tag names are correct
• it's not that hard to implement, because you have already done tag protection
• GitHub doesn't have this 👀
