Documentation

Overview

Package watchdog keeps standing watches available when no codeaf terminal is open. The user-facing surfaces describe the consequence; this package owns the deliberately quiet operating-system details.

Types

type LastWakeFunc 

type LastWakeFunc func() (time.Time, bool, error)

LastWakeFunc reads the newest durable wake observation from the graph journal. Keeping this as a callback prevents the OS package from owning or opening the user's brain file.

type Manager 

type Manager struct {
	// contains filtered or unexported fields
}

Manager installs, removes, and inspects the current user's five-minute timer. It contains no process-local policy state.

func New 

func New(options Options) (*Manager, error)

New resolves defaults and validates the immutable inputs once.

func (*Manager) Install 

func (m *Manager) Install(ctx context.Context) error

Install writes the exact timer definition and asks the current user's OS to use it immediately. Reinstalling repairs drift and is safe.

func (*Manager) Status 

func (m *Manager) Status() (Status, error)

Status derives installation from the definition files and timing from the journal plus the timer's fixed cadence. It never shells out.

func (*Manager) Uninstall 

func (m *Manager) Uninstall(ctx context.Context) error

Uninstall stops the timer and removes its definition. Missing files are already uninstalled and therefore succeed without invoking host commands.

type Options 

type Options struct {
	Platform   string
	HomeDir    string
	Executable string
	UID        int
	Runner     Runner
	LastWake   LastWakeFunc
	Now        func() time.Time
}

Options makes every host-specific input injectable for exact, hermetic tests. Empty values are filled from the current process by New.

type Runner 

type Runner interface {
	Run(ctx context.Context, name string, args ...string) error
}

Runner is the complete process boundary used to load and unload the user timer. Tests provide a recorder; only commandRunner reaches os/exec.

type Status 

type Status struct {
	Installed bool
	// Stale means the installed timer is from before the rename and startup
	// should replace it with the current generation.
	Stale    bool
	LastWake time.Time
	NextDue  time.Time
}

Status is the shared standing-watch view used by doctor and chat grounding.
