DESCRIPTION_SPLITTING_PATTERN =

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.

This pattern is used to split descriptions at full stops. We only consider a dot as a full stop if it is either followed by a whitespace or at the end of the description. In this way we can prevent cutting off a sentence in the middle due to dots in URLs or paths.
