Using bzlmod with Bazel 6

  1. Enable with common --enable_bzlmod in .bazelrc.
  2. Add to your MODULE.bazel file:
bazel_dep(name = "rules_haskell", version = "0.17")

Using WORKSPACE

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")
http_archive(
    name = "rules_haskell",
    sha256 = "298f6f0db23391274b4eca215daa01797d05699469048ef94540d5829b466377",
    strip_prefix = "rules_haskell-0.17",
    url = "https://github.com/tweag/rules_haskell/archive/refs/tags/v0.17.tar.gz",
)

Highlights

  • Support Bazel's new "bzlmod" dependency system
  • Support GHC 9.2.x and 9.4.x

Changed

  • The minimum supported Bazel version is now 6.0.
  • IDE support : Output absolute paths in hie-bios flags (See #1862)
    • haskell_repl now defines an extra runable target name@bios that outputs the hie-bios flags.
    • hie_bios_path_prefix attribute for haskell_repl is a no-op now that we use absolute paths.
  • build_bazel_rules_nodejs dependency is replaced by rules_js which induces some changes to the experimental Asterius support (See [#1884]).
  • Replace use of exec_tools with semantically-identical tools (see #1925)
  • GHC 9.2 and 9.4 are supported and tested, older GHC releases only supported on a best effort basis (see #1878)

Fixed

  • Make the flags passed to Stack match Cabal (see #1913)
  • Fix include directories passed to hsc2hs (see #1922)

Added

  • Add support for Bazel 6
  • Add support for bzlmod (see #1864)
  • The provided cc_toolchain used for windows can now be used with --incompatible_enable_cc_toolchain_resolution so using the crosstool_top option is no longer necessary.
  • Add support for GHC 9.2.5 (see [#1869])
  • Add support for GHC 9.4.5 (linux, macOS) and GHC 9.6.1 (see #1890)

Removed

  • Remove support for Bazel 4
