bazel-coverage-report-renderer v0.9 Release Notes

Release Date: 2019-05-07 // almost 5 years ago

  • Highlights

    👍 The minimum supported Bazel version is now v0.24.

    The version is available from nixpkgs unstable and via
    🚀 official releases.

    🎉 Initial Windows support

    🏁 A non-trivial subset of rules_haskell is now working on Windows.
    See the project tracker
    for finished and ongoing work.

    👌 Improved OSX support

    Due to the mach-o header size limit, we took extra measures to
    👉 make sure generated library paths are as short as possible, so
    🔗 linking haskell binaries works even for large dependency graphs.

    👍 Better Bindist support

    🏗 The default start script sets up a
    0️⃣ bindist-based project by default.

    rules_nixpkgs is no longer a required dependency of
    rules_haskell (but can still be used as backend).

    Full Haskell–C–Haskell Sandwich

    A haskell_library can be now be used nearly anywhere a
    cc_library can.

    The old cc_haskell_import and haskell_cc_import wrapper rules
    🗄 are no longer necessary and have been deprecated.

    👍 Greatly improved REPL support

    A new haskell_repl rule allows to load multiple source targets by
    source, or compiled, as needed. Example usage:

    haskell_repl(
  name = "my-repl",
  # Collect all transitive Haskell dependencies from these targets.
  deps = [
      "//package-a:target-1",
      "//package-b:target-2",
  ],
  # Load targets by source that match these patterns.
  include = [
      "//package-a/...",
      "//packaga-b/...",
      "//common/...",
  ],
  # Don't load targets by source that match these patterns.
  exclude = [
      "//package-a/vendored/...",
  ],
)

    👌 Support for GHC plugins

    🔌 Each haskell_* rule now has a plugins attribute. It takes a
    list of bazel targets, which should be haskell_librarys that
    🔌 implement the GHC plugin
    specification    .

    🎉 Initial Code Coverage support

    👀 Measure coverage of your Haskell code. See the “Checking Code
    ✅ Coverage”
    section in the manual.

    Compatibility Notice

    🔀 hazel was merged into
    rules_haskell    , but
    we are not yet certain about the exact interface we want to expose.
    🚀 hazel is therefore not included in this release, and we can’t
    guarantee the original, unmerged version is compatible with this
    🚀 release. If you depend on hazel, please use a recent master commit
    of rules_haskell.

    🔄 Changed

    haskell_register_ghc_bindists is no longer re-exported from
    //haskell/haskell.bzl.
    You must now load that macro from //haskell:nixpkgs.bzl.

    rules_nixpkgs is no longer a dependency of rules_haskell.

    haskell_import has been renamed to haskell_toolchain_library.
    This is a substantial breaking change. But adapting to it should be
    as simple as

    sed -i 's/^haskell_import/haskell_toolchain_library/' **/BUILD{,.bazel}
sed -i 's/"haskell_import"/"haskell_toolchain_library"/' **/BUILD{,.bazel}

    👀 See #843.

    haskell_toolchain’s tools attribute is now a list of labels.
    Earlier entries take precendence. To migrate, add [] around your
    argument.
    👀 See #854.

    0️⃣ The default outputs of haskell_library are now the static and/or
    📦 shared library files, not the package database config and cache
    files.

    ➕ Added

    • haskell_repl rule that constructs a ghci wrapper that loads
      multiple targets by source.
      👀 See #736.
    • 🔌 plugins attribute to haskell_* rules to load GHC plugins.
      👀 See #799.
    • The HaskellInfo and HaskellLibraryInfo providers are now
      exported and thus accessible by downstream rules.
      👀 See #844.
    • Generate version macros for preprocessors (c2hs, hsc2hs).
      👀 See #847.
    • bindist_toolchain rule gets haddock_flags and repl_ghci_args
      attributes.
    • 🏗 @repl targets write json file with build information, usable by
      IDE tools.
      👀 See #695.

    🗄 Deprecated

    • haskell_cc_import; use cc_library instead.
      👀 See #831.
    • cc_haskell_import; just use haskell_library like a cc_library.
      👀 See #831.

    🛠 Fixed

    • Support protobuf roots in haskell_proto_library.
      👀 See #722.
    • Made GHC bindist relocatable on *nix.
      👀 See #853.
    • 🛠 Various other fixes
