Functions ¶

func From ¶

func From(displayName string) string

From slugifies a free-text display name. Lowercases, replaces runs of non-[a-z0-9] with a single dash, trims leading/trailing dashes, truncates to MaxLen. Returns "" when the input has no usable characters; callers should treat empty as an error.

func Unique ¶

func Unique(base string, exists func(candidate string) bool) string

Unique returns base if exists(base) is false; otherwise base-2, base-3, … until exists returns false. Callers own the uniqueness scope (per-kind index).

func Valid ¶

func Valid(s string) bool

Valid reports whether s is a legal slug (DNS-1123 label, ≤63 chars).

func WithSuffix ¶

func WithSuffix(base string, n int) string

WithSuffix appends "-N" to base, ensuring the result fits in MaxLen by trimming base. N ≥ 2 (callers iterate from 2).
