Function parseRelativeSessionRef

pkg/session/store.go:41–53

parseRelativeSessionRef checks if ref is a relative session reference (e.g., "-1", "-2") and returns the offset and whether it's a relative reference. Returns (1, true) for "-1", (2, true) for "-2", etc. Returns (0, false) if not a relative reference.

(ref string)

// Returns (1, true) for "-1", (2, true) for "-2", etc.
// Returns (0, false) if not a relative reference.
func parseRelativeSessionRef(ref string) (offset int, isRelative bool) {
	if !strings.HasPrefix(ref, "-") {
		return 0, false
	}

	// Try to parse as negative integer
	n, err := strconv.Atoi(ref)
	if err != nil || n >= 0 {
		return 0, false
	}

	return -n, true
}

// ResolveSessionID resolves a session reference to an actual session ID.
// Supports relative references like "-1" (last session), "-2" (second to last), etc.
