This repository provides a Nix file that allows you to find and build all reverse dependencies of a given Haskell package.
This is useful if you want to make a change to a widely-used Haskell package and see which reverse dependencies break.
For instance, if you want to remove a method from
conduit, this can be easily
used to build all Haskell packages with transitive dependencies on conduit
and see what breaks.
Usage instructions are described at the top of default.nix.
Normally, the tool nix-review
is used to rebuild all reverse-dependencies of a file in nixpkgs. However,
nix-review doesn't work with the Haskell package set in nixpkgs, so this
repository is necessary.
