  directory-ospath-streaming
version:
  0.1.0.3
synopsis:
  Stream directory entries in constant memory in vanilla IO
description:

  fashion without storing all directory elements in memory. From another
  perspective, this reading interface allows stopping at any point
  without loading every directory element.

  Both Windows and Unix systems are supported.

-- Cabal will pick this flag up automatically during solving. Default to true
-- since that’s what should be picked up for all future filepath versions starting at 1.5.
