# Revision history for haskell-flake
|
|
|
|
## `master`
|
|
|
|
- #162: **Completely new way to override Haskell packages**: removed `overrides` and `source-overrides`. Use `packages` to specify your source overrides; use `settings` to override individual packages in modular fashion (like NixOS modules). Additional changes include:
|
|
- Add `package.<name>.cabal.executables` referring to the executables in a package. This is auto-detected by parsing the Cabal file.
|
|
- Add `packages.<name>.local.*` to determine of a package is a local package or not.
|
|
- Add `projectFlakeName` option (useful in debug logging prefix)
|
|
- `flake.haskellFlakeProjectModules`: Dropped all defaults, except the `output` module, which now exports `packages` and `settings`. Added a `defaults.projectModules.output` option that allows the user to override this module, or directly access the generated module.
|
|
- Add `project.config.defaults.settings.default` defining sensible defaults for local packages.
|
|
- Add `project.config.defaults.enable` to turn off all default settings en masse.
|
|
- Regressions in this PR: #169, #178
|

## 0.3.0 (May 22, 2023)
|
|
|
|
- #134: Add `autoWire` option to control generation of flake outputs
|
|
- #138: Add `checks` to `outputs` submodule
|
|
- #143: Changed `autoWire` to be an enum type, for granular controlling of which outputs to autowire.
|
|
- #137: Expose cabal executables as flake apps. Add a corresponding `outputs.apps` option, while the `outputs.localPackages` option is renamed to `outputs.packages` (it now contains package metadata, including packages and its executables).
|
|
- #151: Use `lib.getBin` to get the bin output
|
|
- #148: Remove automatic hpack->cabal generation. Use `pre-commit-hooks.nix` instead.
|
|
- #149: Fix unnecessary re-runs of cabal2nix evaluation. Add a `debug` option to have haskell-flake produce diagnostic messages.
|
|
- #153: Add `config.defaults` submodule to allow overriding the default devShell tools added by haskell-flake
|
|
|
|
## 0.2.0 (Mar 13, 2023)
|
|
|
|
- New features
|
|
- #68, #79, #106: Add support for project modules that can be imported in `imports`. Export them in `flake.haskellFlakeProjectModules`. Default modules are exported by default, to reuse overrides and local packages from external flakes. For details, see https://haskell.flake.page/modules
|
|
- #67: `overrides` will be combined using `composeManyExtensions`, however their order is arbitrary. This is an experimental feature, and a warning will be logged.
|
|
- Dev shell
|
|
- #37: Devshell can now be disabled using `devShell.enable = false;` (useful if you want haskell-flake to produce just the package outputs)
|
|
- #92: Add `devShell.mkShellArgs` to pass custom arguments to `mkShell`
|
|
- #111: Add `devShell.extraLibraries` to add custom Haskell libraries to the devshell.
|
|
- #63, #52: Add `config.haskellProjects.${name}.outputs` containing all flake outputs for that project; as well as (#102) `finalPackages` and `localPackages`.
|
|
- #49 & #91 & #110: The default value for the `packages` option is now determined from the `cabal.project` file. If it doesn't exist, it looks for top-level `.cabal` file or `package.yaml`. Better hpack support throughout.
|
|
- #100: `source-overrides` option now supports specifying Hackage versions as string.
|
|
- #114: Prevent unnecessary Nix rebuilds of packages in sub-directories when parent contents change.
|
|
- API changes
|
|
- #37: Group `buildTools` (renamed to `tools`), `hlsCheck` and `hlintCheck` under the new `devShell` submodule option
|
|
- #64: Remove hlintCheck (use [treefmt-nix](https://github.com/numtide/treefmt-nix#flake-parts) instead)
|
|
- #52: Rename `haskellPackages` to `basePackages`. Overlays are applied on top of `basePackage` -- using `source-overrides`, `overrides`, `packages` in that order -- to produce `finalPackages`.
|
|
- #69: The default flake template creates `flake.nix` only, while the `#example` one creates the full Haskell project template.
