This directory works as a single `uv` workspace containing all project packages. See [`packages`](./packages/) to discover all project packages.

## Migrating from 0.2.x?

Please refer to the [migration guide](./migration_guide.md) for how to migrate your code from 0.2.x to 0.4.x.

## Development

**TL;DR**, run all checks with:

```sh
uv sync --all-extras
source .venv/bin/activate
poe check
```

### Setup

`uv` is a package manager that assists in creating the necessary environment and installing packages to run AutoGen.

- [Install `uv`](https://docs.astral.sh/uv/getting-started/installation/).

### Virtual Environment

During development, you may need to test changes made to any of the packages.\
To do so, create a virtual environment where the AutoGen packages are installed based on the current state of the directory.\
Run the following commands at the root level of the Python directory:

```sh
uv sync --all-extras
source .venv/bin/activate
```

- `uv sync --all-extras` will create a `.venv` directory at the current level and install packages from the current directory along with any other dependencies. The `all-extras` flag adds optional dependencies.
- `source .venv/bin/activate` activates the virtual environment.

### Common Tasks

To create a pull request (PR), ensure the following checks are met. You can run each check individually:

- Format: `poe format`
- Lint: `poe lint`
- Test: `poe test`
- Mypy: `poe mypy`
- Pyright: `poe pyright`
- Build docs: `poe --directory ./packages/autogen-core/ docs-build`
- Auto rebuild+serve docs: `poe --directory ./packages/autogen-core/ docs-serve`
- Check samples in `python/samples`: `poe samples-code-check`
Alternatively, you can run all the checks with:
- `poe check`

> [!NOTE]
> These need to be run in the virtual environment.

### Syncing Dependencies

When you pull new changes, you may need to update the dependencies.
To do so, first make sure you are in the virtual environment, and then in the `python` directory, run:

```sh
uv sync --all-extras
```

This will update the dependencies in the virtual environment.

### Creating a New Package

To create a new package, similar to `autogen-core` or `autogen-chat`, use the following:

```sh
uv sync --python 3.12
source .venv/bin/activate
cookiecutter ./templates/new-package/
```
