Regex for URL

Note

Stops at whitespace and leaves off trailing punctuation, so a URL at the end of a sentence doesn’t take the full stop. Parse candidates with the URL constructor to be sure.

Matches in the example

• "https://example.com/docs?page=2#intro"
• "http://localhost:8080"

Token by token

1. http the text “http”
2. s? the character “s”, optionally
3. : the character “:”
4. \/ the character “/”
5. \/ the character “/”
6. [A-Za-z0-9] one of: “A” to “Z”, “a” to “z” or “0” to “9”
7. [^\s]* any character except a whitespace character, zero or more times, as many as possible
8. [^\s.,;:!?)\]'"] any character except a whitespace character, “.”, “,”, “;”, “:”, “!”, “?”, “)”, the character “]”, “'” or “"”
