Variables

var DefaultManager = ""

DefaultManager if not empty is the default package-manager to use when missing

var ErrNotInstalled = errors.New("no candidate installed")

ErrNotInstalled is raised when the candidate package manager is not installed on the host system (use command-line -dry-run to avoid execution errors and just check your buildfile syntax)

var ErrUnknownManager = errors.New("unknown package manager")

ErrUnknownManager is raised when the asked manager does not exist

Types

type PackageManager

type PackageManager interface {
	// SetExecContext sets the execution context, default is os/exec
	SetExecutor(exec.Executor)
	// Name of executable (to check if installed and for debug)
	Name() string
	// Fetch updates the package cache/databse
	Fetch() error
	// Upgrade already installed packages and whatever can be upgraded with warranty (e.g. kernel)
	Upgrade() error
	// Install a given package
	Install(string) error
	// Remove a package given package
	Remove(string) error
}
