This adds support for Cask old tokens used for renames of Casks.
We'll now correctly check these at installation time to avoid repeatedly
installing renamed Casks and dump them in the Brewfile. We also use this
logic to avoid cleaning up renamed Casks.
- Homebrew Bundle referred to formulae as "brews". But it referred to
casks as "casks" and taps as "taps".
- Let's use the same terminology everywhere.
- (I know that `brew "hello"` is the formula syntax in the Brewfile, so
I'm not changing that (though would be up for it, in a backwards
compatible manner), just making the code more consistent.)
This flag allows you to specify formulae to upgrade, even if
`$HOMEBREW_BUNDLE_NO_UPGRADE` is set.
This is useful for upgrading specific formulae without upgrading all
formulae.
While we're here, let's add Sorbet signatures to the `Bundle` module
because I needed to add a new method there anyway.
Extract the relevant logic from `formula.rb`, moving to `keg.rb` and
then use this logic in `bundle/commands/cleanup.rb` to ensure that we
don't say we need to uninstall formulae that should be still kept.
We've had requests for this in Homebrew/bundle a few times so let's
implement it both for there and for `brew edit`.
Tested on my machine with `cursor` and working as expected.
