Support getting the project version (like Rye and poetry) from the pyproject.toml

[itamark-ug]

Hi,
In both poetry and Rye there is an option to run poetry version or rye version and get the project version from the pyproject.toml.

Here is a link to the rye docs:
https://rye.astral.sh/guide/commands/version/

Here is a link to the poetry docs:
https://python-poetry.org/docs/cli/#version

for example, for a project named my-little-helper with a version 2.0.22 the command will emit:
my-little-helper 2.0.22
In poetry there is also an option to add the --short option and the result will be 2.0.22

The motivation for that is to be able to extract the version for automatic tagging a successful package build in a github action.
But I can think of other useful scenarios.

Thanks

I agree that this would be really useful. A workaround to get the version could be:

uv tool install pyproject-parser[cli]
pyproject-info project.version

Thanks, we are already using it in our code, for now (till uv will support it) I will use your workaround in our build action. Thanks

We're interested, but need to design the interface.

Note pyproject-info project.version returns the version with the surrounding quotes, I used pyproject-info project.version | xargs to remove them.

uv tool install pyproject-parser[cli]
pyproject-info project.version

For anyone else trying this and getting: BadConfigError: Unexpected top-level key 'dependency-groups'. Only 'build-system', 'project' and 'tool' are allowed.

Use a later tag from https://github.com/repo-helper/pyproject-parser/tags
This worked for me:

uv tool install pyproject-parser[cli]>=v0.13.0b1
pyproject-info project.version
