How to develop Trattoria

Trattoria involves 3 repos and some compiled code so getting up and running a dev environment for it is not as trivial as I would like it.

The following instructions are a first step towards making it easier for newcomers and future me to setup.

  1. Clone trattoria, trattoria-core and tttr-toolbox.
  2. In trattoria-core modify the Cargo.toml file so that it picks up tttr-toolbox not from crates.io but from a local folder on your computer. This will have to be undone before you push a new version to crates.io.
  3. Create a Python venv and move into it.
  4. Assuming you are still inside the trattoria-core you should now run poetry install. This will install the required Python dependencies.
  5. Now you can run poetry run maturin develop which will compile the rust components and make them available from within the venv. You can test this by opening a Python interpreter and import trattoria_core.
  6. Without leaving the venv move to the trattoria repo. Open the pyproject.toml file and comment out the trattoria-core dependency. This will temporatily disable the dependency on trattoria-core so that the next step doesnt attempt to fetch trattoria-core from pypi which we haven't up.
  7. Now poetry install and finally check that everythin works by starting a REPL and and verifying you can import trattoria.

Reached this point you can start developing trattoria-core and tttr-toolbox and test the code by calling it from Python using trattoria. Remember that between changes you will have to rerun step 5 above.
