# convert-poetry2uv
The convert_poetry2uv.py script is meant to easily convert the pyproject.toml to be consumed by `uv` instead of `poetry`.
> Poetry v2 came out after this tool. The tool has been modified to work with poetry v2 format as well. Please create an issue/PR if you find any issues.
It has a dry-run flag, to have a temporary file to validate the output. When not running the dry-run the original file is saved with a .org extension.
uv run convert_poetry2uv.py [-n]
You may need to make some manual changes.
The layout might not be exactly to your liking. I would recommend using [Even better toml](https://marketplace.visualstudio.com/items?itemName=tamasfe.even-better-toml) in VSCode. Just open the newly generated toml file and save. It will format the file according to the toml specification.
## Caveats
* If you were using the poetry build-system, it is removed in the generated pyproject.toml.
* if you had optional dev groups, the dev group libraries will be used, the optional flag is removed
# Using as a tool
The script can be run as a tool using [`uvx`](https://docs.astral.sh/uv/guides/tools/)
uvx convert-poetry2uv --help
## uv instructions
Once the pyproject.toml is converted, you can use `uv` to manage your project. To start fresh, the .venv directory is removed followed by the creation and sync of the .venv directory.
rm -rf .venv
uv venv # or 'uv venv -p 3.12' to specify a python version
uv sync
With this you are good to go and are able to validate the migration was a success.
## Pypi
The script is also available on pypi as [convert-poetry2uv](https://pypi.org/project/convert-poetry2uv/)
pip install convert-poetry2uv
# Contribute
Though I've tried to make it as complete as possible, it is not guaranteed to work for all cases. Feel free to contribute to the code or create an issue with the toml file that is not converted correctly.
## Versions/Releases
The version is automatically updated with `python-semantic-release`. Take note of the `pyproject.toml` to see which keywords can be added to the commit message to ensure the correct version is released. The release is created when merged to main.
