Slug Generator

Turn an arbitrary string into a URL-friendly slug.

Rules

1. Convert the string to lowercase.
2. Replace any run of whitespace with a single -.
3. Strip all characters that are not ASCII letters (a-z), digits (0-9), or -.
4. Collapse any run of consecutive - into a single -.
5. Strip leading and trailing -.
6. If the result is longer than 60 characters, truncate it. If truncation lands on a -, also strip that trailing -.
7. If the result is empty, return the literal string untitled.

Examples

• "Hello, World!" → "hello-world"
• " multiple spaces " → "multiple-spaces"
• "!!!" → "untitled"
