Method Guard

cli/coder/input_guard.go:144–153

Guard runs the full pre-prompt sequence: flush TTY → drain channel. Callers should invoke this BEFORE rendering the UI, then call IntentDebounce AFTER the UI is rendered. Returns true if any layer discarded user input — callers may want to surface this in the UI ("ignored prefilled input").

(ch <-chan string)

// Returns true if any layer discarded user input — callers may want to
// surface this in the UI ("ignored prefilled input").
func (g *InputGuard) Guard(ch <-chan string) bool {
	anyDiscarded := false
	if err := g.FlushTTYInput(); err != nil {
		g.logger.Debug("input guard: FlushTTYInput failed (non-fatal)", zap.Error(err))
	}
	if drained := g.DrainStdinChannel(ch); len(drained) > 0 {
		anyDiscarded = true
	}
	return anyDiscarded
}

// preview returns a short, escape-stripped excerpt of an input line for
// safe logging. We never want to dump full user input to the log.
