SyntaxError: invalid syntax
Introduced on May 2, 2024 with bc0f5ee62a
`brew bump-formula-pr` is encountering a type error, as the inferred
return type of `GitHub#check_for_duplicate_pull_requests` doesn't
align with the explicit return type of `#check_pull_requests`:
```
Error: Return value: Expected type T.nilable(T::Array[String]), got
type Module with value T::Private::Types::Void::VOID
Caller: /home/linuxbrew/.linuxbrew/Homebrew/Library/Homebrew/dev-cmd/
bump-formula-pr.rb:137
Definition: /home/linuxbrew/.linuxbrew/Homebrew/Library/Homebrew/
dev-cmd/bump-formula-pr.rb:472 (Homebrew::DevCmd::BumpFormulaPr
#check_pull_requests)
```
This addresses the issue by adding a type signature with a `void`
return type to `#check_for_duplicate_pull_requests` and setting the
return type of `#check_pull_requests` to `void` as well. The return
type from `#check_pull_requests` isn't used, so a `void` return type
is arguably a better reflection of the method's behavior. The
`#check_pull_requests` method in `BumpCaskPr` has a `void` return
type, so this change brings the `BumpFormulaPr` method in line.
- change the messaging depending on how confident we are that we're
actually looking at duplicates i.e. we're not confident without a
version number supplied
- similarly, just warn instead of failing with an error (and no
override) if we're not confident that we're looking at duplicates
because a version wasn't supplied
- change `bump-cask-pr` and `bump-formula-pr` to always check for all
pull requests with the new version number (to allow failing on this)
rather than only checking closed pull requests with a version number
- change `bump` to check for definite/maybe duplicate PRs and only
exit if they are definitely duplicates
- cleanup some variable usage to DRY things up a bit
On macOS 14 and newer, `/usr/libexec/path_helper` supports setting a
`PATH_HELPER_ROOT` environment variable.
With this set, `path_helper` checks `$PATH_HELPER_ROOT/etc/paths` and
`$PATH_HELPER_ROOT/etc/paths.d` in the same way it checks `/etc/paths`
and `/etc/paths.d`.
We can use this to simplify management of the user's `PATH` variable
when they do `brew shellenv`. In particular, if their system supports
it, we delegate setting the `PATH` environment variable to `path_helper`
instead of our own code. We also write a default `etc/paths` file if one
is not already present.
This is nicer because it simplifies management of the user's `PATH`
variable. For example, if a user wants a keg-only formula to be in their
`PATH`, they can simply add the necessary path to `/etc/paths` or
`/etc/paths.d` without having to do something like `brew link --force`
or adding to `PATH` themselves.
When `/usr/libexec/path_helper` is not available, we just fall back to
the existing code.
