Highlights

  • Moved to exclusive support of Bazel 4
  • Support for GHC 8.8, 8.10, 9.0 and 9.2
  • Asterius support (experimental)
  • Cross-compilation support
  • haskell_module rule (experimental)

Added

  • Support for Bazel 4.1.0 and 4.2.1
  • Support for GHC 8.8.4, 8.10.3, 8.10.4, 8.10.7, 9.0.1 and 9.2.1.
  • Blacklisted empty ghc-byteorder package.
  • More reproducible GHC bindist on macOS.
    See #1462.
  • Track GHC's lib/settings as an action input by exposing a files attribute in the haskell_toolchain rule, which is used in downstream actions.
    See #1478.
  • Added ghc-bignum to the list of core packages (since GHC 9.0.1).
  • Provided a Bazel-compatible version of ghc-paths.
    See #1508.
  • Allow different repository names when registering Haskell toolchains for cross-compiling.
  • Added hsc2hs into the inputs of cabal_wrapper so it can be found when cross-compiling.
  • Support for platform constraints for GHCs in Nixpkgs.
  • Added hie_bios_path_prefix to the haskell_repl rule to allow hie-bios to output paths relative to a directory besides the workspace root.
  • Experimental haskell_module rule, with profiling, hs-boot, plugin, preprocessor, package database, dynamic build and Template Haskell support.
    See #1553.
  • Support for Cabal sublibraries, using the sublibrary_name attribute of the haskell_cabal_library rule.
  • Added generates_path_module attribute to haskell_cabal_library, such that its data files are accessible to haskell_binary rules.
    See #1575.
  • Added non_default_plugins attribute to haskell_library and haskell_binary rules to avoid setting -fplugin for every module.
  • Support for using Template Haskell and FFI with static C dependencies.
    See #1582.
  • Support for Asterius.
    See #1614, #1618, #1619, #1621, #1643 and #1660.
  • Support for sublibraries in the stack_snapshot rule.
    See #1638.
  • Support for the --incompatible_override_toolchain_transition flag.

Removed

  • Support for Bazel pre-4.0.0

Changed

  • Source file names are explicitly mapped to module names and corresponding object and interface files in Starlark. The main module is determined heuristically, but can be overridden with the main_file attribute.
    See #1281.
  • stack unpack now uses versioned packages.
    See #1455.
  • cabal_wrapper now takes its arguments as JSON.
  • Use GitHub API token in stack_snapshot pinning, if available, to avoid rate limiting.
    See #1494.
  • Invoke a runghc for the execution platform in cabal_wrapper.
  • compiler_flags options have been renamed to ghcopts in macros and rules, for consistency. The old name will still work, but has been deprecated.
  • Automatic visibility of stack_snapshot dependencies to vendored packages.
    See #1583.
  • All REPL targets are tagged as manual, so are only built on-demand.
  • Use a more deterministic distdir path in haskell_cabal_* rules to improve reproducibility.
    See #1648.

Fixed

  • stack_snapshot pinning with archives containing Cabal files located deeper down the tree.
  • A regression whereby dynamically linked binaries were missing their libraries in the runfiles.
  • Compatibility issue with macOS Big Sur.
    See #1442.
