Unreleased

  • Add a reusable workflow for managed bounds updates.
  • Parse Nix json output messages to diagnose problems; add overrides for installed packages that fail with a bounds error printed by Cabal.
  • Replace envs.<env>.derivations by per-output-category flags in packages.<package>.expose to control which packages are included in outputs.
  • Added envs.<env>.expose analogous to package exposition config.
  • Added dev to the scoped envs to allow access to excluded derivations.
  • Add override combinators for toggling Cabal flags.
  • Remove packages with env name prefix (ghc96-hix) in favor of scoped derivations in legacyPackages (ghc96.hix).
  • Expose intermediate and final build outputs as nested sets of environments and packages via module arguments build and outputs.

0.7.0: Hix Unbound: Majors Apart

  • Fetch thax from a static URL, removing the flake input.
  • Fix environment not being set when using direnv.
  • Add an app, bump, that updates dependency versions and tests the build before writing new bounds and overrides to a file that's incorporated into the build.
  • Add an app, lower, that determines the lowest dependency versions with which the project builds.
  • Add the option envs.<name>.hoogle to pass withHoogle to ghcWithPackages.
  • Change the semantics of the option profiled to enable executable profiling. The old behavior has been moved to the option libraryProfiling.
  • Add an environment profiled whose executables, with profiling enabled, are exposed as flake outputs like .#hix.profiled and .#env.profiled.hix.
  • Add a new attribute to package outputs, musl, that uses the natively built toolchain available in pkgsMusl, as an alternative to the existing cross.musl64.

0.6.9

  • Add the option haskellTools globally and per-env, which allows specifying shell tools that should be made available from the env's GHC without overrides.
  • Separate the effect of the option profiling from env.<name>.localPackage.
  • Add flake apps that build AppImage distributions using nix-appimage as .#appimage, .#<exename>.appimage, .#env.<envname>.<exename>.appimage.
  • Add hooks to release process.

0.6.7

  • The option hackage.add allows changed files to be git-added, but not committed, during release when hackage.commit is false.
  • Default to main package when none was specified for ghci(d) commands in multi-package projects.

0.6.6

  • Expose environment packages as legacyPackages.<system>.<env>.<package> for each entry in ghcVersions.
  • Expose local packages, ghc and pkgs for each env as legacyPackages.<system>.env.<env>.{<package>,ghc,pkgs}.

0.6.2

  • When releasing, the word 0.6.2 can be automatically replaced by the new version in changelogs when hackage.setChangelogVersion is true (default off).

0.6.1

  • Allow envs to be excluded from being exposed as devShells for specific systems.
  • Add an app, dep-versions, that prints all components' direct dependencies and their actual version in an environment.

0.6.0

  • Support multiple Cabal libraries in a single package.
  • Add GHCi(d) CLI options --ghci-options and --ghcid-options.
  • Allow cabal2nix derivations in overrides to be pre-generated and stored in a file to avoid IFD.

0.5.5

  • Per-package versionFile is now used for the version field in Cabal files.

0.5.2

  • Custom prelude preprocessor no longer mistakes modules with the prefix Prelude for the real thing.

0.5.1

  • Add the top-level option buildInputs that specifies non-Haskell deps for all packages.

0.5.0

  • Switch off IFD (i.e. cabal2nix) by default, allowing multiple systems to be exposed while still allowing flake checks to work.
  • Change directory to the package root when running GHCi.
  • Add the option package.<name>.override that allows transforming a derivation with override combinators.
  • Add the option package.<name>.buildInputs that specifies non-Haskell deps for a package.

0.4.0.0

  • Add commands for bootstrapping new and existing projects.

0.1.0.0

  • Major rewrite moving Cabal config into the packages option.
  • Add environments as a generalization of the GHC module.
  • Add commands as a generalization of the GHCid runner.
  • Add a CLI tool that acts as a GHC preprocessor for injecting extensions and prelude when running GHCi.
