The following is an example of a package command:

The following package managers are recognized:

• apt

package command args

You can add additional arguments using the standard Args key. This is useful for adding more packages.

Development

The PackageManager interface provides an easy to enforce functions and options. There are two interfaces, PackageManager and ConfigurablePackageManager in the directory pkg/pkgman. Go's import-cycle "feature" caused me to implement functional options using a third interface. PackageManagerOptionis a function that takes an interface.

PackageManager

// PackageManager is an interface used to define common package commands. This shall be implemented by every package.
type PackageManager interface {
	Install(pkg, version string, args []string) (string, []string)
	Remove(pkg string, args []string) (string, []string)
	Upgrade(pkg, version string) (string, []string) // Upgrade a specific package
	UpgradeAll() (string, []string)

	// Configure applies functional options to customize the package manager.
	Configure(options ...pkgcommon.PackageManagerOption)
}

There are a few functional options that should be implemented using the ConfigurablePackageManager interface:

// ConfigurablePackageManager defines methods for setting configuration options.
type ConfigurablePackageManager interface {
	SetUseAuth(useAuth bool)
	SetAuthCommand(authCommand string)
}
