Overview

Package updater implements `shepherd update`: it checks the latest GitHub release, downloads the matching release archive, verifies its checksum, and atomically replaces the running executable.

Types

type CheckInfo 

type CheckInfo struct {
	Current   string `json:"current"`
	Latest    string `json:"latest"`
	Available bool   `json:"available"`
}

CheckInfo is the result of a cached update check.

func CachedCheck 

func CachedCheck(ctx context.Context, repo, current string) CheckInfo

CachedCheck returns whether a newer release is available, using a 24h on-disk cache to avoid hitting the network on every invocation. It is best-effort: any error yields Available=false and never surfaces. Dev builds are never flagged as out of date.

type Result 

type Result struct {
	Current   string `json:"current"`
	Latest    string `json:"latest"`
	UpToDate  bool   `json:"up_to_date"`
	Updated   bool   `json:"updated"`
	Asset     string `json:"asset,omitempty"`
	Path      string `json:"path,omitempty"`
	CheckOnly bool   `json:"check_only"`
}

Result describes the outcome of an update check/run.

func Update 

func Update(ctx context.Context, repo, current string, checkOnly bool) (Result, error)

Update checks repo's latest release against current and, unless checkOnly, installs it over the running binary.
