cabal-version: 3.0

-- Created : 27 April 2023

x-revision: 1
name:
  directory-ospath-streaming
version:
  0.2
synopsis:
  Stream directory entries in constant memory in vanilla IO
description:
  Reading of directory contents in constant memory, i.e. in an iterative
  fashion without storing all directory elements in memory. From another
  perspective, this reading interface allows stopping at any point
  without loading every directory element.

  Also defines general-purpose recursive directory traversals.

  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.
