Import these from the homebrew/aliases tap and deprecate that tap.
This required a little messing around with class/module/constant names
to get `brew tests` and `brew typecheck` to play nicely.
I added also added Sorbet type signatures and integration tests.
Allow the ability for a system administrator to use
`HOMEBREW_BREW_WRAPPER` and `HOMEBREW_FORCE_BREW_WRAPPER` variables to
enforce the usage of a particular `brew` command for non-trivial (e.g.
`brew --prefix` is considered trivial, it doesn't need to write to the
prefix) Homebrew commands.
This also introduces a `HOMEBREW_ORIGINAL_BREW_FILE` variable for some
internal usage; `HOMEBREW_BREW_FILE` was being used internally for
both "how should we shell out to Homebrew" and "what should we use
to check permissions on Homebrew". `HOMEBREW_ORIGINAL_BREW_FILE` is
now used just for the latter case.
Inspired by conversation in
https://github.com/Homebrew/homebrew-bundle/pull/1551 which suggested
this was worth fixing in wider than just `brew bundle`.
- 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
Offenses:
bad.rb:1:1: C: Sorbet/StrictSigil: Sorbet sigil should be at least strict got true.
^^^^^^^^^^^^^
1340 files inspected, 1 offense detected
```
- Move HOMEBREW_TAP_DIRECTORY to startup/config.rb because this file
holds more of the directory constants
- Rename `Commands.cmd_directories` to `Commands.tap_cmd_directories`
to better express that the commands come from taps
This file has the directory constants while the other one has regexes.
Just better organization.
This improves the load time of most brew commands. For an example of
one of the simplest commands this speeds up:
Without Bootsnap:
```
$ hyperfine 'git checkout master; brew help' 'git checkout optimise_requires; brew help'
Benchmark 1: git checkout master; brew help
Time (mean ± σ): 525.0 ms ± 35.8 ms [User: 229.9 ms, System: 113.1 ms]
Range (min … max): 465.3 ms … 576.6 ms 10 runs
Benchmark 2: git checkout optimise_requires; brew help
Time (mean ± σ): 383.3 ms ± 25.1 ms [User: 133.0 ms, System: 72.1 ms]
Range (min … max): 353.0 ms … 443.6 ms 10 runs
Summary
git checkout optimise_requires; brew help ran
1.37 ± 0.13 times faster than git checkout master; brew help
```
With Bootsnap:
```
$ hyperfine 'git checkout master; brew help' 'git checkout optimise_requires; brew help'
Benchmark 1: git checkout master; brew help
Time (mean ± σ): 386.0 ms ± 30.9 ms [User: 130.2 ms, System: 93.8 ms]
Range (min … max): 359.5 ms … 469.3 ms 10 runs
Benchmark 2: git checkout optimise_requires; brew help
Time (mean ± σ): 330.2 ms ± 32.4 ms [User: 93.4 ms, System: 73.0 ms]
Range (min … max): 302.9 ms … 413.9 ms 10 runs
Summary
git checkout optimise_requires; brew help ran
1.17 ± 0.15 times faster than git checkout master; brew help
```
Similarly to have we have with other commands, use Bash to speed it up.
Before:
```
$ hyperfine "brew list"
Benchmark 1: brew list
Time (mean ± σ): 559.9 ms ± 122.8 ms [User: 176.2 ms, System: 126.2 ms]
Range (min … max): 503.2 ms … 907.3 ms 10 runs
```
After:
```
$ hyperfine "brew list"
Benchmark 1: brew list
Time (mean ± σ): 223.7 ms ± 31.9 ms [User: 35.0 ms, System: 53.4 ms]
Range (min … max): 198.1 ms … 302.4 ms 10
```
Petty after comparison because someone on Homebrew/discussions compared
them:
```
$ hyperfine "brew list" "pip3 list"
Benchmark 1: brew list
Time (mean ± σ): 213.1 ms ± 22.8 ms [User: 34.2 ms, System: 49.2 ms]
Range (min … max): 191.2 ms … 272.3 ms 13 runs
Benchmark 2: pip3 list
Time (mean ± σ): 271.7 ms ± 4.6 ms [User: 191.9 ms, System: 40.0 ms]
Range (min … max): 264.7 ms … 281.4 ms 10 runs
Summary
brew list ran
1.28 ± 0.14 times faster than pip3 list
```

While we're here, also add the `HOMEBREW_CASKROOM` environment variable
to make things a bit cleaner and use `--caskroom` in documentation.
