- Suppress (some more) warnings when doing `brew install --quiet`
- Clarify `man brew` output that we don't suppress all warnings
for all commands with `--quiet`
While I was doing this I noticed references to the (soon to be
deprecated) `brew switch` so:
- remove these references in `install` output
- remove a reference in the documentation
- add a comment to remind me to deprecate `brew diy`, too
Fixes#9179
Fix `-1` and other flags so they're handled correctly with casks. Use
the "right" exceptions for declaring invalid combinations and change
their parent class so that `--help` is printed nicely too.
Fixes#9033
The way we currently handle @-versioned formulae linking is pretty
labourius:
- it requires extensive use of `link_overwrite` to avoid the `link`
stage failing on certain install/upgrade scenarios
- we teach people to use `brew link --force` whenever they wish to
link a versioned formulae when it's pretty obvious what's expected
in that situation
Instead, let's:
- automatically unlink other versioned formulae when linking a
versioned formula (either through `brew link` or `install`/`upgrade`
/`reinstall`)
- notify the user what we've done (with the same messaging as if
they had run `brew link` manually)
- Run `brew search` for local formulae first (as it's quickest) rather
than checking Git history.
- Don't output `Searching taps...` because `Searching taps on GitHub...`
is output by the called function (and because it'll say it's searching
taps even when it is not if `HOMEBREW_NO_GITHUB_API` is set).
GitHub has requested we request our usage of shallow clones. As a
result:
- do default to shallow clones on CI
- do not do --shallow-since when setting up new repositories in
`brew update`
- do not support shallow clones of homebrew-core at all
We may consider in future unshallowing all clones unconditionally.
