Details

Package update replaces the running binary with the latest published release, using the same installer the website serves.

View Source

const ScriptURL = "https://www.postline.dev/install.sh"

ScriptURL is the installer on postline.dev. The site proxies the copy in the repository, so a push to install.sh is what this command runs.

This section is empty.

func AlreadyCurrent(installed, latest string) bool

AlreadyCurrent reports whether the installed binary is the published tag. A "dev" build is never current: it was produced without a release.

func ArchiveName(goos, goarch, version string) string

ArchiveName is the GoReleaser artifact for a given OS, arch, and version number (no leading v).

func DirOf(executable string) string

DirOf is the directory a binary lives in, which is where --update writes.

func Normalize(v string) string

Normalize strips a leading v so "v0.1.0" and "0.1.0" compare equal.

func Run(installedVersion string) error

Run downloads the website installer and points it at the directory of the current executable, so the replacement lands on top of this binary.
