Since client code uses the package name as a prefix when referring to the package contents, the names for those contents need not repeat the package name. - Rename base.BaseCommand to base.Command - Rename base.BaseServer to base.Server - Rename config.DevConfig() to config.Dev() - Rename config.LoadConfigFile() to config.LoadFile() - Rename config.NewConfig() to config.New() - Rename config.ParseConfig() to config.Parse() - Rename controller.ControllerCommand to controller.Command - Rename controller.NewController() to controller.New() - Rename dev.DevCommand to dev.Command - Rename listener.ListenerFactory to listener.Factory - Rename listener.NewListener() to listener.New() - Rename version.GetVersion() to version.Get() - Rename version.VersionInfo to version.Info See: - https://golang.org/doc/effective_go.html#package-names - https://blog.golang.org/package-names#TOC_3. - https://github.com/golang/go/wiki/CodeReviewComments#package-names
