.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)
