# NIX-SPECIFIC OVERRIDES/PATCHES FOR HASKELL PACKAGES
#
# This file contains overrides which are needed because of Nix. For example,
# some packages may need help finding the location of native libraries. In
# general, overrides in this file are (mostly) due to one of the following reasons:
#
# * packages that hard code the location of native libraries, so they need to be patched/
#   supplied the patch explicitly
# * passing native libraries that are not detected correctly by cabal2nix
# * test suites that fail due to some features not available in the nix sandbox
#   (networking being a common one)
#
# In general, this file should *not* contain overrides that fix build failures that could
# also occur on standard, FHS-compliant non-Nix systems. For example, if tests have a compile
# error, that is a bug in the package, and that failure has nothing to do with Nix.
#
# Common examples which should *not* be a part of this file:
#
# * overriding a specific version of a haskell library because some package fails
#   to build with a newer version. Such overrides have nothing to do with Nix itself,
#   and they would also be neccessary outside of Nix if you use the same set of
#   package versions.
# * disabling tests that fail due to missing files in the tarball or compile errors
# * disabling tests that require too much memory
# * enabling/disabling certain features in packages
#
# If you have an override of this kind, see configuration-common.nix instead.
{ pkgs, haskellLib }:

let
  inherit (pkgs) lib;
in

with haskellLib;

# All of the overrides in this set should look like:
#
#   foo = ... something involving super.foo ...
#
# but that means that we add `foo` attribute even if there is no `super.foo`! So if
# you want to use this configuration for a package set that only contains a subset of
# the packages that have overrides defined here, you'll end up with a set that contains
# a bunch of attributes that trigger an evaluation error.
#
# To avoid this, we use `intersectAttrs` here so we never add packages that are not present
# in the parent package set (`super`).
