Overview ¶

Package hostbin resolves host binaries that live outside the PATH a daemon inherits. lerd-ui and lerd-watcher are started by launchd (or systemd), which hands them a minimal PATH — on macOS literally /usr/bin:/bin:/usr/sbin:/sbin — so a tool the user installed with Homebrew is invisible to exec.LookPath even though it works fine in their terminal. Anything a daemon may have to run goes through here so the CLI and the daemons resolve the same binary.

var ExtraDirs = func() []string {
	if runtime.GOOS == "darwin" {
		return []string{"/opt/homebrew/bin", "/usr/local/bin"}
	}
	return []string{"/usr/local/bin", "/snap/bin", "/home/linuxbrew/.linuxbrew/bin"}
}

ExtraDirs lists the install prefixes a daemon's PATH leaves out: both Homebrew prefixes on macOS (Apple Silicon and Intel), and the equivalents on Linux. Ordered the way a login shell would see them. A var so tests can point it at a fixture instead of depending on what the host has installed.

Functions ¶

func Look ¶

func Look(name string) (string, bool)

Look resolves name to an absolute path: PATH first, then the extra dirs. Reports false when the binary is nowhere to be found.

func Path ¶

func Path(name string) string

Path is Look for callers building a command line: it returns the resolved absolute path, or the bare name so the failure surfaces as the OS's own "executable file not found" rather than as a silent substitution.
