Function parseGithubSource

internal/metadata/catalog.go:233–266

parseGithubSource extracts owner, repo, branch and in-repo path from a GitHub URL or "owner/repo" shorthand. It supports the permalink, tree, and blob forms used by awesome-list catalogs: https://github.com/owner/repo https://github.com/owner/repo/tree/main/skills/foo https://github.com/owner/re
