Make the Homebrew/cask and Homebrew/homebrew-core style more closely
match the rest of Homebrew.
To accomplish this:
- Run `brew cask style` to ensure we don't break style there when
making changes or upgrading RuboCop in Homebrew/brew.
- Fix the HomepageMatchesUrl cop to better handle weird input.
- Remove the now unneeded `.rubocop_shared.yml`
- Fix the cask fixtures with `brew cask style --fix`.
- Share more style between Homebrew/brew, casks and formulae.
In some cases, certain Casks shouldn't be resubmitted for specific reasons: difficult to maintain, developers maintain their own version, ...
To make sure these cases are restricted - we can add them to a blacklist and have the blacklist checked as part of the `brew cask audit` steps.
In a number of Cask specs, the value of the `homepage` stanza is currently set
to https://example.com. As of 2018-11-28, the TLS certificate served by
example.com seems to be expired, possibly due to an oversight on ICANN’s side.
While the certificate is certainly going to be renewed soon, it would be
desirable for Homebrew’s test result to be less dependent on ICANN’s actions.
This commit changes the homepages of all test Casks to http://brew.sh, whose
domain and TLS certificate are both controlled by Homebrew.
`brew cask list` supports the `--full-name` flag which will include the tap
name for casks not part of the core caskroom/cask tap. For example, if
cask "foo-beta" is installed from the caskroom/versions cask, `brew cask
list --full-name` will report the name as "caskroom/versions/foo-beta".
