mengine

a lambda-DAG based proof engine

the main idea: https://dspace.mit.edu/handle/1721.1/162908

building

to build, you need clang and make. on macOS, you'll also need argp-standalone:

brew install argp-standalone
make

on linux, argp is part of glibc so just:

make

if you use clangd as your language server, you can also generate a .clangd:

make clangd

usage

./mengine
./mengine path/to/script.me
./mengine --help  # for options

check out examples/ for example scripts showing the syntax.

status

this is a prototype! my goals include:

• examples of verifying large imperative programs
• all proofs continue to generate Coq-checkable proof terms
• a tactic scripting language for writing new tactics
