WORKSPACE.nix.part

#
# The content of file is inserted into WORKSPACE (replacing the part between
# the cut-marks) when building using bazel-in-nix (that is, via `nix-build -A
# tests release.nix`).
#
# The content sets up the haskell toolchains without requiring rules_nixpkgs,
# which won't work when inside a nix-build (due to nix-in-nix prohibition).
#
# The toolchain directories (`prebuilt_*`) are pre-arranged by release.nix. The
# bazel rule calls below just replicate what rules_haskell would do with the
# nix-sourced toolchains.
