Function Truncate

pkg/stringutil/stringutil.go:20–30

Truncate truncates a string to a maximum length, adding "..." if truncated. If maxLen is 3 or less, the string is truncated without "...". This is a general-purpose utility for truncating any string to a configurable length. For domain-specific workflow command identifiers with newline handling, se

(s string, maxLen int)

// length. For domain-specific workflow command identifiers with newline handling,
// see workflow.ShortenCommand instead.
func Truncate(s string, maxLen int) string {
	if len(s) <= maxLen {
		return s
	}
	if maxLen <= 3 {
		stringutilLog.Printf("Truncate: hard-cut at maxLen=%d (no ellipsis)", maxLen)
		return s[:maxLen]
	}
	stringutilLog.Printf("Truncate: shortened from %d to %d chars", len(s), maxLen)
	return s[:maxLen-3] + "..."

// NormalizeWhitespace normalizes trailing whitespace and newlines to reduce spurious conflicts.
// It trims trailing whitespace from each line and ensures exactly one trailing newline.
