magic-1.1.2: magic.cabal

cabal-version:      2.4
name:               magic
version:            1.1.2
synopsis:           Interface to C file/magic library
description:
  This package provides a Haskell interface to the C libmagic library.
  With it, you can determine the type of a file by examining its contents
  rather than its name.  The Haskell interface provides a full-featured
  binding.
  .
  Note: this package requires the C libmagic library (part of the @file@
  package) and its development headers to be installed at build time.

flag pkgconfig
  description:
    Use pkg-config to locate the C libmagic library. Enabled by default;
    because this flag is automatic, Cabal's solver transparently falls back
    to plain @extra-libraries@ linking when pkg-config or libmagic.pc is
    unavailable.
  default: True
  manual:  False

flag dev
  description: Turn on developer settings, notably -Werror.
  default:     False
  manual:      True

-- Strict warning set shared by all components. Based on -Weverything with the
-- pedantic / Safe-Haskell / style categories that the existing bindings cannot
-- satisfy without source changes disabled. The genuine bug-catching warnings
-- (unused bindings, incomplete patterns, name shadowing, missing local/export
-- signatures, type defaults, ...) remain ON. -Werror is opt-in via the `dev`
-- flag so a normal build, Hackage, or Stackage is never broken by a future
-- GHC introducing new warnings.
