raehik / pladlang

A toolchain for a collection of simple lambda calculus languages. (Originally for the 2020 UKC CO663 module.)

Pladlang: Tools for a simple exemplar programming language

This is a set of tools for Pladlang, a generalisation of some simple lambda calculus-like languages introduced in the 2020 UKC module CO663 Programming Languages: Application and Design (-> PLAD). It started off as a formal type derivation builder to let me cheat on part of an assessment, and grew much later as I learned more Haskell.

Main usage: Takes an equation written in a simple language inspired by the lambda calculus and build a formal type derivation for it in LaTeX macros via the mathpartir package.

Usage

Pladlang is built with Stack, so with it installed:

stack ghci

Then run wild. Examples are stored in Pladlang.Examples and prepended with ex or assess. (TODO)

To compile the LaTeX output, you'll need LaTeX with a bunch of packages including mathpartir. (TODO)
