# A repository wide shell.nix containing all tools, formatters, and inputs
# required to build any of the C or Haskell packages.
#
# Entering a nix-shell using this derivation will allow you to cd anywhere
# in the ./pkg directory and run the appropriate build tooling.
#
# See the individual ./pkg/* directories for shell.nix derivations that only
# propagate minimal sets of buildInputs for the related package.

# The non-Haskell packages which build inputs (dependencies) will be
# propagated into the shell. This combines nixpkgs' mkShell behaviour
# with Haskell.nix's shellFor.
#

# made available, so you can just run make.

# Typically the inputs listed here also have a shell.nix in their respective
# source directory you can use, to avoid the Haskell/GHC dependencies.
