- Instead use class methods.
- This is better than use it as a mixin
when only a small number of methods are
used in each class or module.
- It also allows us to conditionally
require it in `brew install`.
- Removed unused search require in descriptions.rb.
Now the search_name method takes the command line
args and only returns package types that line up
with those args.
That means it will only return casks if casks are valid
and same with formulae.
- provide specific install instructions
when a cask/formula doesn't exist
and we search for similar ones
- print and exit early if a named formula that
was removed recently has the same name
- exit early if the tap is specified because
we don't get good search results
- Move `search_names` and `print_missing_formula_help` out of `cmd/search.rb` to `search.rb`
- Change to using those functions in `cmd/install.rb` when a formula or cask doesn't exist
Allows you to avoid the `Keg::ConflictError` recommending that you invoke `brew link --overwrite` in scenarios when you know that that's how you'd proceed anyway.
There's a few bits of functionality that Homebrew has changed over the
years, makes sense as a sensible default but some people find really
annoying:
- automatically running `brew update`
- automatically running `brew cleanup`
- automatically upgrading outdated dependents
- automatically reinstalling broken dependents
For each of these: let's improve the documentation of the commands
whose behaviour is changed and the environment variables themselves.
Otherwise if there's no search results then there's no indication what
was being searched for:
```
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching for a previously deleted formula (in the last month)...
Error: No previously deleted formula found.
==> Searching taps on GitHub...
Error: No formulae found in taps.
```
