Thank you for investing time in contributing to our project! Here's a guide to get you started.
First things first, let's get you a personal copy of Letta to play with. Think of it as your very own playground. 🎪
- Head over to the Letta repository on GitHub.
- In the upper-right corner, hit the 'Fork' button.
Now, let's bring your new playground to your local machine.
git clone https://github.com/your-username/letta.git
First, install Poetry using the official instructions here.
Once Poetry is installed, navigate to the Letta directory and install the Letta project with Poetry:
cd Letta
poetry shell
poetry install --all-extras
Now when you want to use letta
, make sure you first activate the poetry
environment using poetry shell:
$ poetry shell
(pyletta-py3.12) $ letta run
Alternatively, you can use poetry run
(which will activate the poetry
environment for the letta run
command only):
poetry run letta run
We recommend installing pre-commit to ensure proper formatting during development:
poetry run pre-commit install
poetry run pre-commit run --all-files
If you don't install pre-commit, you will need to run poetry run black .
before submitting a PR.
Time to put on your creative hat and make some magic happen. First, let's create a new branch for your awesome changes. 🧙♂️
git checkout -b feature/your-feature
Now, the world is your oyster! Go ahead and craft your fabulous changes. 🎨
If you are running Letta for the first time, your database will be automatically be setup. If you are updating Letta, you may need to run migrations. To run migrations, use the following command:
poetry run alembic upgrade head
If you have made changes to the database models, you will need to create a new migration. To create a new migration, use the following command:
poetry run alembic revision --autogenerate -m "Your migration message here"
Visit the Alembic documentation for more information on creating and running migrations.
Before we hit the 'Wow, I'm Done' button, let's make sure everything works as expected. Run tests and make sure the existing ones don't throw a fit. And if needed, create new tests. 🕵️
Running tests if you installed via poetry:
poetry run pytest -s tests
Running tests if you installed via pip:
pytest -s tests
If you added a major feature change, please add new tests in the tests/
directory.
If you need to add a new dependency to Letta, please add the package via poetry add <PACKAGE_NAME>
. This will update the pyproject.toml
and poetry.lock
files. If the dependency does not need to be installed by all users, make sure to mark the dependency as optional in the pyproject.toml
file and if needed, create a new extra under [tool.poetry.extras]
.
Please ensure your code is formatted correctly by running:
poetry run black . -l 140
You're almost there! It's time to share your brilliance with the world. 🌍
- Visit Letta.
- Click "New Pull Request" button.
- Choose the base branch (
main
) and the compare branch (your feature branch). - Whip up a catchy title and describe your changes in the description. 🪄
The maintainers, will take a look and might suggest some cool upgrades or ask for more details. Once they give the thumbs up, your creation becomes part of Letta!
Please be sure to follow the project's Code of Conduct.
Need help or just want to say hi? We're here for you. Reach out through filing an issue on this GitHub repository or message us on our Discord server.
Thanks for making Letta even more fantastic!
If you prefer to keep your resources isolated by developing purely in containers, you can start Letta in development with:
docker compose -f compose.yaml -f development.compose.yml up
This will volume mount your local codebase and reload the server on file changes.
