Multivariant assignments generation language

This library allows you to write short description of multivariant assignments in embedded DSL and interpret them as solution, text of assignment and tests.

This library is available at hackage.

Installation

install stack
run stack exec multivariant

or you can use cabal install multivariant.

Language description

There are several typeclasses for tagless-final encoding of language:

Program
WithDescription
WithCornerCases
WithInvert

Each typeclass defines some operations that every interpreter has to implement.

There are currently three ``interpreters'' (types that implement corresponding typeclasses):

Cases
Description
Solution

WithInvert

Examples

task = Inv.map ((+1) :<->: (-1)) `withDescription` "Add one to each list element" `withCornerCases` ([0],[0])
    ~>   (   (sum :<->: (\s -> [s,0])) `withDescription` "Compute sum of elements" `withCornerCases` ([[]],[0])
	   <+++> (product :<->: (\p -> [1,p])) `withDescription` "Compute product of elements" `withCornerCases` ([[]],[1])
	     )
