Overview

This class is part of a private API. This class may only be used in the Homebrew/brew repository. Third parties should avoid using this class if possible, as it may be removed or changed without warning.

A Tap is used to encapsulate Homebrew formulae, casks and custom commands. Usually, it's synced with a remote Git repository. And it's likely a GitHub repository with the name of user/homebrew-repository. In such cases, user/repository will be used as the #name of this Tap, where #user represents the GitHub username and #repository represents the repository name without the leading homebrew-.

This constant is part of a private API. This constant may only be used in the Homebrew/brew repository. Third parties should avoid using this constant if possible, as it may be removed or changed without warning.

Hosts where a .git suffix and trailing slashes are known not to change which repository a remote identifies, so we can safely strip them. We don't assume this for arbitrary hosts (including self-hosted GitLab, Forgejo, and GitHub Enterprise) where repo.git and repo may differ.

REMOTE_SCHEME_USERINFO_REGEX =

This constant is part of a private API. This constant may only be used in the Homebrew/brew repository. Third parties should avoid using this constant if possible, as it may be removed or changed without warning.

An optional RFC 3986-ish scheme:// (e.g. https://, ssh:// or git+https://) followed by optional user@ userinfo: the part of a remote URL that can precede the host.

%r{(?:[a-z][a-z0-9+.-]*://)?(?:[^@/]+@)?}
GITHUB_REMOTE_PREFIX_REGEX =

This constant is part of a private API. This constant may only be used in the Homebrew/brew repository. Third parties should avoid using this constant if possible, as it may be removed or changed without warning.

The leading <scheme>://<user>@github.com/ of a GitHub URL or the SCP-style <user>@github.com: shorthand. The : form is only SCP syntax when there is no scheme; with a scheme a : starts a port rather than the path, so it must not be rewritten.

%r{\A(?:[a-z][a-z0-9+.-]*://(?:[^@/]+@)?github\.com/|(?:[^@/]+@)?github\.com:)}
REMOTE_HOST_REGEX =

This constant is part of a private API. This constant may only be used in the Homebrew/brew repository. Third parties should avoid using this constant if possible, as it may be removed or changed without warning.

The host of a remote: the first /- or :-delimited segment after any scheme and userinfo.

.normalize_remote(remote) ⇒ String?

This method is part of a private API. This method may only be used in the Homebrew/brew repository. Third parties should avoid using this method if possible, as it may be removed or changed without warning.

On GitHub the scheme and userinfo are insignificant (any of HTTPS, SSH SCP syntax, ssh:// or git:// identify the same repository), so those forms are canonicalised to HTTPS. For hosts in NORMALIZE_REMOTE_HOSTS a .git suffix and trailing slashes are also insignificant, so we strip them; we don't assume that for other hosts.

Parameters:

  # Canonicalise every GitHub remote form to `https://github.com/<owner>/<repo>` so SSH and
  # HTTPS remotes for the same repository compare equal.
  remote = remote.sub(GITHUB_REMOTE_PREFIX_REGEX, "https://github.com/")

  # Only strip `.git`/trailing slashes for hosts where this is known to be safe.
  host = remote[REMOTE_HOST_REGEX, 1]
  return remote unless NORMALIZE_REMOTE_HOSTS.include?(host)

  remote.sub(%r{/+\z}, "").delete_suffix(".git")
end

.remote_reference?(reference) ⇒ Boolean

This method is part of a private API. This method may only be used in the Homebrew/brew repository. Third parties should avoid using this method if possible, as it may be removed or changed without warning.

Whether an allow/forbid/trust list reference is a remote URL or local path rather than a user/repository tap name (which can only match a tap on its default GitHub remote). A genuine remote reference is a URL (contains ://), scp-like syntax ([user@]host:path, i.e. a non-empty path after a : before any /, the same way Git itself detects scp syntax) or a local path (starts with /, . or ~). A bare foo@bar or host: is not one.

Parameters:

Returns:

  • (Boolean)

def self.remote_reference?(reference)
  reference.match?(%r{\A[^/]+:.}) || reference.start_with?("/", ".", "~")
end

.remote_to_reference(url) ⇒ String?

This method is part of a private API. This method may only be used in the Homebrew/brew repository. Third parties should avoid using this method if possible, as it may be removed or changed without warning.

Converts a remote URL to the canonical trust-list reference for the tap it identifies. A default-style GitHub remote canonicalises to the owner/repo name form (matching how #reference works for an installed tap); any other remote is stored as the normalised URL. Returns nil if the URL is blank or otherwise invalid.

#install(quiet: false, clone_target: nil, custom_remote: false, verify: false, force: false) ⇒ void

This method returns an undefined value.

Install this Tap.

Parameters:

  • quiet (Boolean) (defaults to: false) —

    If set, suppress all output.

  • clone_target (Pathname, String, nil) (defaults to: nil) —

    If passed, it will be used as the clone remote.

  • custom_remote (Boolean) (defaults to: false) —

    If set, change the tap's remote if already installed.

  • verify (Boolean) (defaults to: false) —

    If set, verify all the formula, casks and aliases in the tap are valid.

  • force (Boolean) (defaults to: false) —

    If set, force core and cask taps to install even under API mode.
