Pytanque

Pytanque is a Python API for lightweight communication with the Rocq proof assistant.

Install

You should setup a virtual env first, e.g., using pyenv virtualenv:

pyenv virtualenv 3.12.2 pytanque
pip install -e .

Usage

First start the pet-server (https://github.com/gbdrt/coq-lsp/tree/pytanque)

cd /path/to/coq-lsp/petanque
dune exec -- pet-server

Then, the class Pytanque is the main entry point to communicate with the Petanque server. Assuming you have a coq file named tests/foo.v which contains a theorem addnC you can try the following.

from pytanque import Pytanque

with Pytanque("127.0.0.1", 8765) as pet:
    state = pet.start(file="./examples/foo.v", thm="addnC")
    state = pet.run_tac(state, "induction n.", verbose=True)
    state = pet.run_tac(state, "auto.", verbose=True)
    state = pet.run_tac(state, "lia.", verbose=True)

You can quickly try a similar example with

python examples/foo.py
