Functions ¶

func AssetName ¶

func AssetName(tag string) string

AssetName returns the release archive name for this platform.

func AssetURL ¶

func AssetURL(tag, name string) string

AssetURL returns the download URL for a named asset of a release.

func CurrentExecutable ¶

func CurrentExecutable() (string, error)

CurrentExecutable resolves the real path of the running binary.

func Download ¶

func Download(ctx context.Context, url string) (string, error)

Download fetches url into a temp file and returns its path.

func ExtractBinary ¶

func ExtractBinary(archivePath string) (string, error)

ExtractBinary pulls the chunder executable out of the release archive into a temp file and returns its path.

func IsHomebrew ¶

func IsHomebrew(exe string) bool

IsHomebrew reports whether the binary lives in a Homebrew cellar, where brew should manage upgrades instead of us.

func LatestTag ¶

func LatestTag(ctx context.Context) (string, error)

LatestTag resolves the newest release tag by following GitHub's releases/latest redirect. Unlike the REST API, this is not rate-limited, so it works from shared IPs without a token.

func Replace ¶

func Replace(exe, newBin string) error

Replace atomically swaps the executable at exe with the file at newBin. The temp copy must land on the same filesystem for rename to be atomic, so it is staged next to the target first.

func Verify ¶

func Verify(ctx context.Context, archivePath, assetName, checksumsURL string) error

Verify checks the archive against the release's checksums.txt.
