Functions

func CheckInstalled

func CheckInstalled(goenvInstallDirectory string, version string) error

CheckInstalled simply checks if a directory exists.

func CheckLatestGo

func CheckLatestGo() error

CheckLatestGo looks for new stable versions of Go. If new stable versions have been released since the last check, then we'll let the user know. We only print this message once per new set of releases.

func CheckLatestGoenv

func CheckLatestGoenv(ctx context.Context, currentVersion *semver.Version) error

CheckLatestGoenv checks the Github releases for a new version of Goenv. If one is found, the one-line install instructions are printed to the console.

func CheckRW

func CheckRW(goenvRootDirectory string, goenvInstallDirectory string) []string

CheckRW checks if the user can install and use Go by making sure they have read and write access to the directories where go will be installed.

func CreateGoVersionList

func CreateGoVersionList(directories []string) map[string][]string

CreateGoVersionList will take a list of all the directories in goenv and then parse it into a GoVersionList. We do this so that we can print the installed Go versions nicely for the user.

func Debug

func Debug(mesg string)

func DownloadFile

func DownloadFile(v *semver.Version) (filepath string, err error)

DownloadFile will download a url to a local file. If we have a recorded shasum for the file, we'll check it. We'll return a path to the downloaded file. https://go.dev/dl/go1.18.linux-amd64.tar.gz

func Error

func Error(mesg string)

func ExtractTarGz

func ExtractTarGz(tarballPath, destinationPath string) error

ExtractTarGz will do the equivalent of a tar -xzvf -C and untar the tarball to whichever destination path we need to go to.

func Info

func Info(mesg string)

func ListAvailableVersions

func ListAvailableVersions(getAllVersions bool) ([]string, error)

ListAvailableVersions reads all available versions of Go that can be installed. It queries go.dev for what's available. By default, it'll return only the latest patches of the two most recent minor versions. For example: 1.18: 1.18.7 1.19: 1.19.2

func Print

func Print(g map[string][]string, linePrefix string)

Print will nicely display the installed and available versions of Go you can install to the terminal.

func Success

func Success(mesg string)

func Warn

func Warn(mesg string)
