Types

type InstallOption

type InstallOption struct {
	DryRun bool // 模擬 install, 只會印出相關訊息, 但所有的 install 指令都不會執行
	Force  bool // 表示如果當前已經安裝過, 會強制移除重新安裝
	Soft   bool // soft means remove exist plugin only if version is different
}

InstallOption 封裝了跟安裝有關的控制

type Installer

type Installer interface {
	Install() (*plugin.Plugin, error)
}

Installer 抽象化了 plugin 的安裝實作

func NewInstaller

func NewInstaller(log *logrus.Logger, source string, tag string, asset int, home paths.Home, opt *InstallOption) (Installer, error)

NewInstaller 依照傳入的資訊取得 plugin 的安裝實作
