Pattern

regexengine-agnostic

https?:\/\/(?:www\.)?github\.com\/([A-Za-z0-9](?:[A-Za-z0-9\-]{0,38})?)\/([A-Za-z0-9._\-]{1,100})   (flags: g)

Raw source: https?:\/\/(?:www\.)?github\.com\/([A-Za-z0-9](?:[A-Za-z0-9\-]{0,38})?)\/([A-Za-z0-9._\-]{1,100})

How it works

https?:\/\/(?:www\.)?github\.com\/ matches the domain with optional www and either http/https. The first capture ([A-Za-z0-9](?:[A-Za-z0-9\-]{0,38})?) follows GitHub's username rules: 1–39 chars, alphanumeric + hyphens, no leading/trailing hyphen (simplified). The second capture matches the repo name with the broader allowed character set.
