name: ghc-typelits-natnormalise
version: 0.7.10
synopsis: GHC typechecker plugin for types of kind GHC.TypeLits.Nat
description:
A type checker plugin for GHC that can solve /equalities/ and /inequalities/
of types of kind @Nat@, where these types are either:
.
* Type-level naturals
.
* Type variables
.
* Applications of the arithmetic expressions @(+,-,*,^)@.
.
It solves these equalities by normalising them to /sort-of/ @SOP@
(Sum-of-Products) form, and then perform a simple syntactic equality.
.
For example, this solver can prove the equality between:
.
@
(x + 2)^(y + 2)
@
.
and
.
@
4*x*(2 + x)^y + 4*(2 + x)^y + (2 + x)^y*x^2
@
.
Because the latter is actually the @SOP@ normal form of the former.
.
To use the plugin, add the
.
@
OPTIONS_GHC -fplugin GHC.TypeLits.Normalise
@
.
Pragma to the header of your file.
