Thank you! That's good to know. Unfortunately it doesn't seem to work for "extras". There may be some target other than sync.include-groups but I haven't found it yet.
What I am struggling with is what you get after following the Configuring Accelerators With Optional Dependencies example:
Part of what that does is set up rules that prevent simultaneously installing cpu and gpu versions (which isn't possible). If you use the optional dependencies example pyproject.toml then this is what happens:
$ uv sync --extra cpu --extra cu124
Using CPython 3.12.7
Creating virtual environment at: .venv
Resolved 32 packages in 1.65s
error: Extras `cpu` and `cu124` are incompatible with the declared conflicts: {`project[cpu]`, `project[cu124]`}
And if you remove the declared conflict, then uv ends up with two incompatible sources to install the same packages from
uv sync --extra cpu --extra cu124
error: Requirements contain conflicting indexes for package `torch` in all marker environments:
- https://download.pytorch.org/whl/cpu
- https://download.pytorch.org/whl/cu124
After your comment I initially thought that perhaps the extras might be rewritten as group dependencies somehow to use the ~/.config/uv/config.toml but according to the docs group dependencies are not allowed to have conflicts with each other and must be installable simultaneously (makes sense since there is an --all-groups flag). That is you must be able to install all group dependencies simultaneously.
1. Create or edit the UV configuration file in one of these locations:
- `~/.config/uv/config.toml` (Linux/macOS)
- `%APPDATA%\uv\config.toml` (Windows)
2. Add a section for default groups to sync:
```toml
[sync]
include-groups = ["dev", "test", "docs"] # Replace with your desired group names
```
Alternatively, you can do something similar in pyproject.toml if you want to apply this to the repo:
```toml
[tool.uv]
sync.include-groups = ["dev", "test", "docs"] # Replace with your desired group names
```
