* Move Haskell stuff into separate module cf. https://github.com/hercules-ci/flake-parts/blob/main/modules/apps.nix * Parametrize the haskell part * Allow user to override default attrs * Add baseBuildTools (so they can be overriden) * Don't hardcode non-essential build tools * Avoid types.anything * Merge into one buildTools, using sets * getExe and type are redundant Co-authored-by: Robert Hensing <roberth@users.noreply.github.com> * Use docstring wherever possible * Use ${self} as default for root * Allow defining multiple Haskell packages The downside: the user is forced to define 'default' flake outputs. * Automatically create 'default' attr if a singleton projects set * Make haskell.nix its own repo Co-authored-by: Robert Hensing <roberth@users.noreply.github.com>
