working fine: please don't worry or file an issue; just ignore this. Thanks!

Warning: Some installed kegs have no formulae!
This means they were either deleted or installed manually.
You should find replacements for the following formulae:
  python-jinja
  python-click
  connect-offset-reset

Warning: Some taps are not on the default git origin branch and may not receive

Warning: Homebrew's "sbin" was not found in your PATH but you have installed
formulae that put executables in /usr/local/sbin.
Consider setting your PATH for example like so:
  echo 'export PATH="/usr/local/sbin:$PATH"' >> /Users/weilero/.bash_profile

Description of issue

Hi!

As Homebrew seems to be able to reliably deduce the version from the formula's URL, I wonder if the same applies to a resource? I Homebrew able to deduce a resource's version?

I guess I could easily do this manually by inspecting the URL, but was wondering if Homebrew is already able to do so.

[ZhongRuoyu]

Yes, the version of a resource can also be deduced from the URL. See clang-format.rb for example, where we have:

odie "clang resource needs to be updated" if build.stable? && version != resource("clang").version

Awesome! Thanks for the quick answer.
