Functions ¶

func AssetURL ¶

func AssetURL(assets []Asset) string

AssetURL returns the download URL for the binary matching the current OS and architecture, or an empty string if no matching asset was found.

func IsNewer ¶

func IsNewer(tagName, currentVersion string) bool

IsNewer reports whether tagName is a newer release than currentVersion.

Both values may be "vX.Y.Z", "vX.Y.Z-N-gHASH" (git describe output), or a bare commit hash. A bare hash is treated as older than any semver tag so that users on pre-release dev builds always receive an upgrade prompt.

func Run ¶

func Run(currentVersion string, cmd *cobra.Command)

Run checks for a newer release and, if one exists, downloads it and replaces the running binary. Called by the `em update` command.

Types ¶

type Asset ¶

type Asset struct {
	Name               string `json:"name"`
	BrowserDownloadURL string `json:"browser_download_url"`
}

Asset is a single downloadable file attached to a release.

type Release ¶

type Release struct {
	TagName string  `json:"tag_name"`
	Assets  []Asset `json:"assets"`
}

Release is a minimal representation of a GitHub Release API response.

func LatestRelease ¶

func LatestRelease() (*Release, error)

func LatestReleaseFor ¶

func LatestReleaseFor(repo string) (*Release, error)
