$\lambda$-Compiler

A Primitive Compiler from $\lambda$-calculus + $\alpha$ (e.g. primitive operations, recursion, and effects) to C, based on Call-By-Push-Value (CBPV)

Usage

$ lamc [EXAMPLE_ID] [(-c|--direct-c) (-o|--output OUTPUT_FILE) | [--am]]

For details of each option, please check lamc --help.

Autocompletion

$\lambda$-compiler supports bash, zsh, and fish completion provided by optparse-applicative. To use that, users can check their documentation about autocompletion.

Current Status

Currently, this repository implements a primitive compiler from Call-By-Value $\lambda$-calculus to C based on Call-By-Push-Value (CBPV) and a primitive compiler from CBV $\lambda$-calculus to abstract machine (AM) for CBPV. This repository also comes with an interpreter for AM.
