Functions

func InstallOptionalDeps

func InstallOptionalDeps(groups []*Group, logger flog.Logger) error

InstallOptionalDeps installs the supplied dependency groups.

Since the groups are all optional, InstallOptionalDeps continues to install the remaining groups even if a group fails to be installed. It returns a non-nil error if any of the groups fails to be installed.

Types

type Dependency

type Dependency interface {
	RequiresRoot() bool
	Installed() bool
	Install() error
}

Dependency is a dependency of the Finch binary. It can be a binary, a package, or a file, etc.

type Group

type Group struct {
	// contains filtered or unexported fields
}

Group contains logically related dependencies.

func NewGroup

func NewGroup(deps []Dependency, desc string, errMsg string) *Group

NewGroup views deps as ordered dependencies, and the returned Group will only install them in the order specified here.
