This repository contains the code used in the bachelor thesis project about formally proving the correctness of currying and uncurrying refactoring. The research project is done for the 2022/2023 edition of the CSE3000 Research Project at Delft University of Technology. For this project, a simple Haskell-like language (HLL) was created to show a proof-of-concept for the refactoring.

-- Original function
f1 : (Int, Int) → Int
f1 (x, y) = x + y

-- Function after currying
f2 : Int → Int → Int
f2 = λ x → (λ y → x + y)

An example of currying refactoring, where uncurrying is the transformation from f2 back to f1.

This project uses Agda version 2.6.3, as well as Agda standard library version 1.7.2.

There has been some progress done on the currying which uses tuples instead of special language constructs. For anyone interested in continuing the work and implementing it with tuples, this might be a good starting point.
