About

This library is part of incipit, a set of Prelude modules for the Polysemy ecosystem. It contains the reexports from base that are inherited by the other two packages.

Usage

Using a custom Prelude requires the use of Cabal mixins to hide the module from base and replace it with IncipitBase:

For hpack:

dependencies:
  - name: base
    version: '>= 4 && < 5'
    mixin:
      - hiding (Prelude)
  - name: incipit-base
    version: '>= 0.3'
    mixin:
      - (IncipitBase as Prelude)
      - hiding (IncipitBase)

For cabal:

build-depends:
    base >=4 && <5, incipit-base >= 0.3
mixins:
    base hiding (Prelude), incipit-base (IncipitBase as Prelude), incipit-base hiding (IncipitBase)

incipit-base used to export Prelude, but stack can’t deal with that.
