- These were previously being manually fixed which is time maintainers
could have spent fixing more important problems.
- I don't work with Casks much at all, so I was unsure as to what the
existing "arch" and "on_arch_conditional" parts were, if they're
deprecated or if things were eventually going to migrate to
`on_#{arch}` blocks?
- This skips over stanza names that are not overrideable in `on_*`
blocks, with the positive side effect that `on_*` blocks themselves
aren't in the list so we can get rid of another conditional.
- Stanzas overrideable in blocks are defined in `Cask::DSL` by each of
the methods calling `set_unique_stanza`.
- This came up in Cask `simply-fortran`:
```

arch arm: "-arm64", intel: "-x86_64"
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

```
- This passes the previously failing test for `on_*` blocks with
`livecheck` blocks with multiple stanzas inside them (eg `url` and
`strategy`) that weren't being correctly skipped because we weren't
detecting high enough up the ancestry.
- The Cask `sip`, to give a random example, was failing this RuboCop
because it has a `livecheck` block within an `on_*` block and the
livecheck block and the top-level Cask both have `url` stanzas. This
is a legitimate use of `livecheck` blocks because the cask software
download URL and the livecheck version check URL are not the same
thing, so let's skip over `livecheck` blocks and their contents.
- Otherwise syntax like this, where `#{arch}` is an interpolation,
causes an offense:
```ruby
cask "transcribe" do
arch arm: "_arm"
on_catalina :or_older do
version "8.75.2"
sha256 "f01781100cd3b9987c8f8892145a2eaa358df07b92e10e26f30b6a877f5b352c"
url "https://www.seventhstring.com/xscribe/downmo/transcribe#{version.no_dots}.dmg"
livecheck_version = "10"
end
on_big_sur :or_newer do
livecheck_version = "11"
version "9.21"
sha256 :no_check
url "https://www.seventhstring.com/xscribe/transcribe#{arch}.dmg"
end
[...]
end
```
```
Casks/transcribe.rb:2:3: C: Cask/NoOverrides: Do not use a top-level arch stanza as the default. Add it to an on_{system} block instead.
Use :or_older or :or_newer to specify a range of macOS versions.
arch arm: "_arm"
^^^^^^^^^^^^^^^^

```
- In the event that there's only one common stanza within the `on_*`
blocks (eg, `url`) with a generic `version` that doesn't change per-OS,
let's not force adding `version` to each `on_*` block as well.
- As discussed in
https://github.com/Homebrew/brew/pull/14976#issuecomment-1474544569
and further comments, this is needed because in order to enforce the
order of `on_{arch,system}` blocks we need to have everything
consistently within one of those blocks.
- We previously allowed overrides where the top-level `version` stanza
would be the default, unless on an OS that had an `on_system` block
with a `version` specified. But this breaks down when we try to order
the `on_system` blocks because if a `url` at the top-level has a
`version` interpolated in it, then the `version` stanza needs to be
above the `url` stanza. But it could be that `version` is OS-specific.
- Let's stop allowing overrides and require that everything be in an
`on_system` block. This will make it easier to enforce the order of
`on_system` blocks in a future PR (14976).
- I suspect these were copy-pasted from other cops, like I did in
https://github.com/Homebrew/brew/pull/14886#discussion_r1125569999.
- The "forwardable" require is unnecesary if the cop doesn't
`extend Forwardable` and use `def_delegator`.
- The "uri" require is unnecessary if the cop doesn't call `URI` methods.
- The `on_url_stanza` method is now used in two cops, `Url` and
`UrlLegacyCommaSeparators`. Make the latter inherit from the former
to make Sorbet happy.
- The style and typecheck checks now pass fine.
- Apparently the "verified" parameter in the URL (present when a Cask's
download URL is not the same as its homepage) shouldn't have the
protocol (`https`, `http`) at the front.
- Removing this has happened manually in the past, so here's an
autocorrecting RuboCop for it.
- These are arbitrary length limits that had a load of disables in code.
- The limits were only increasing over time rather than decreasing.
- Fixing the problematic code to be shorter would take a long time for
questionable gain since the problem has been around so long.
