Instance Method Details
#available_version(i) ⇒ Object
Packages (formula) available to install should have a “stable” version, per the Homebrew project’s acceptable formula documentation, so we will rely on that being the case. Older implementations of this provider in the homebrew cookbook would fall back to brew_info, but the schema has changed, and homebrew is a constantly rolling forward project.

#brew_info ⇒ Object
We implement a querying method that returns the JSON-as-Hash data for a formula per the Homebrew documentation. Previous implementations of this provider in the homebrew cookbook performed a bit of magic with the load path to get this information, but that is not any more robust than using the command-line interface that returns the same thing.

#installed_version(i) ⇒ Object
Some packages (formula) are “keg only” and aren’t linked, because multiple versions installed can cause conflicts. We handle this by using the last installed version as the “current” (as in latest). Otherwise, we will use the version that brew thinks is linked as the current version.

#upgrade_package(names, versions) ⇒ Object
upgrades are a bit harder in homebrew than other package formats. If you try to brew upgrade a package that isn’t installed it will fail so if a user specifies the action of upgrade we need to figure out which packages need to be installed and which packages can be upgrades. We do this by checking if brew_info has an entry via the installed_version helper.
