  • livecheck_references (Array<Formula, Cask::Cask>) (defaults to: [])
  • json (Boolean) (defaults to: false)
  • full_name (Boolean) (defaults to: false)
  • verbose (Boolean) (defaults to: false)
  • debug (Boolean) (defaults to: false)

.resource_version(resource, formula_latest, json: false, full_name: false, debug: false, quiet: false, verbose: false) ⇒ Hash{Symbol => T.untyped}

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.

Identifies the latest version of a resource and returns a Hash containing the version information. Returns nil if a latest version couldn't be found.

Parameters:

  • resource (Resource)
  • formula_latest (String)
  • json (Boolean) (defaults to: false)
  • full_name (Boolean) (defaults to: false)
  • debug (Boolean) (defaults to: false)
  • quiet (Boolean) (defaults to: false)
  • verbose (Boolean) (defaults to: false)

Returns:

.use_homebrew_curl?(formula_or_cask, url) ⇒ 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.

livecheck should fetch a URL using brewed curl if the formula/cask contains a stable/url or head URL using: :homebrew_curl that shares the same root domain.

Parameters:

Returns:

  • (Boolean)
