- move some things out of `extend` that don't really fit there e.g.
`Module`s that are included but not doing any
overriding/monkeypatching
- move some code into `extend/os` to fix all remaining
`rubocop:todo Homebrew/MoveToExtendOS`s
- remove some unneeded `bundle` skipper code that doesn't really make
sense given our current bottling strategy
- extract some `Pathname` extensions to `extend/pathname` for separate
files
- move a `ENV` `Kernel` extension into `kernel.rb`
- `odeprecate` a seemingly unused backwards compatibility method
- move `readline_nonblock` from a monkeypatch to a
`ReadlineNonblock.read` method as its only used in one place
- fix up a link in documentation
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.
The existing code for handling a `HEAD`-only formula involves two
return values that can be `nil` but this isn't apparent because the
related methods aren't typed. This adds type signatures to the
methods and updates the livecheck code to account for `nil` return
values (making it clear which methods can return `nil`).

Currently, `brew link` installs `*.info` files to
`#{HOMEBREW_PREFIX}/share/info/dir` using the `install_info` method.
However, some formulae (e.g., `Emacs`) also ship `*.info.gz` files,
which are only `symlink`ed but not installed.
This commit allows `*.info.gz` files to be installed during linking in
addition to the `*.info` files.
- Previously I thought that comments were fine to discourage people from
wasting their time trying to bump things that used `undef` that Sorbet
didn't support. But RuboCop is better at this since it'll complain if
the comments are unnecessary.
- Suggested in https://github.com/Homebrew/brew/pull/18018#issuecomment-2283369501.
- I've gone for a mixture of `rubocop:disable` for the files that can't
be `typed: strict` (use of undef, required before everything else, etc)
and `rubocop:todo` for everything else that should be tried to make
strictly typed. There's no functional difference between the two as
`rubocop:todo` is `rubocop:disable` with a different name.
- And I entirely disabled the cop for the docs/ directory since
`typed: strict` isn't going to gain us anything for some Markdown
linting config files.
- This means that now it's easier to track what needs to be done rather
than relying on checklists of files in our big Sorbet issue:
```shell
$ git grep 'typed: true # rubocop:todo Sorbet/StrictSigil' | wc -l
268
```
- And this is confirmed working for new files:
```shell
$ git status
On branch use-rubocop-for-sorbet-strict-sigils
Untracked files:
(use "git add <file>..." to include in what will be committed)
Library/Homebrew/bad.rb
Library/Homebrew/good.rb
nothing added to commit but untracked files present (use "git add" to track)
$ brew style

This improves the load time of most brew commands. For an example of
one of the simplest commands this speeds up:
Without Bootsnap:
```

This updates logic to add a `#scheme_and_version` method to be used
with `.sort_by` and `.max_by`. Using `Keg#version` by itself can be
inaccurate when different version schemes are present. This also
updates the behavior of `Formula#eligible_kegs_for_cleanup` to match
the previous behavior. We were dropping the wrong keg based on the
sort being reversed in a previous PR.
When a Keg is unlinked, brew-link gives a helpful message for how to proceed: adding the `--overwrite` flag.
For safety, it also recommends running in `--dry-run` mode first to see what would be deleted.
So a user's common flow would be:
1. run `brew link foo`
2. get error message with guidance
3. run `brew link --overwrite --dry-run foo`
4. inspect
5. run `brew link --overwrite foo`
In this flow, steps 3-5 are likely very common. Common enough that a user may use their shell history to re-populate their prompt with step 3's command, delete the `--dry-run` flag, and re-run. (The end goal, of course, is to link `foo`.)
The `--dry-run` flag needs to be removed from the command, of course. If it had been at the _end_ of the command, it would make the subsequent modification easier.
Instead of "up arrow, left-arrow a bunch, then backspace over --dry-run, hopefully not backspacing over the formula name", it would be easier for the user if the dry-run flag were already at the end of the command. Then the user can "up arrow, backspace a few times and hit enter".
What's more, if the last arg were `--dry-run`, a more advanced bash user could even use `!:-` to re-run the link command with all-but-the-last-arg.
This allows us to remove all the manual timestamp fiddling and lets
`gnu-tar` handle it for us instead (as-per the most recent
recommendations on https://reproducible-builds.org/docs/archives/).
Some formulae (e.g. `luv`) have a `lib/lua/5.1` subdirectory inside
their keg. Before this change, the `5.1` subdirectory is symlinked into
`HOMEBREW_PREFIX`.
This can result in `luarocks` installing things into a formula's keg,
which we don't want.
Let's fix that by making sure that `brew link` creates these
subdirectories instead of symlinking them. We already do this for
subdirectories of `share/lua`:
