Read Version Number from the Package in setup.cfg

Hi,

I am trying to make a project to be setup.cfg project. In the old version, we letted the setup.py read a version number from a file inside the package.

def get_version() -> dict:
    version = {}
    with open(Path(__file__).parent / 'sciunit' / 'version.py') as f:
        exec(f.read(), version)
    return version['__version__']

setup(
    ...
    version=get_version(),
    ...
    )

I am wondering how can I achieve the same thing in setup.cfg file? Is it possible?

I’ve answered this question at https://stackoverflow.com/questions/72357031/set-version-of-module-from-a-file-when-configuring-setuptools-using-setup

Method 1:

• Create a __version__.py file at the same level as __init__ of your import package.
• Add to that file: __version__ = '0.0.2'
• In __init__.py, add from . __version__ import __version__.
• In setup.cfg, use version = attr: my_package.__version__ Method 2:
• Create a VERSION file at the same level as __init__ of your import package.
• Add to that file only: 0.0.2
• • Importantly: Don’t enclose in quotation marks. NO OTHER TEXT. No comments
• In setup.cfg use: version = file: src/my_package/VERSION
• • Note that the root for the relative path is the project directory.

Hi, I had the same question as well.

In the docs, there is the section “Specifying Your Project’s Version”. But it didn’t led me to the only spot I could find that includes the answer, which is “Configuring setup() using setup.cfg files” (specifically, the config example’s [metadata] section). I guess it makes sense to link to there from the first section I mentioned?

As for the example itself, which is:

[metadata]
# …
version = attr: src.VERSION

Is this really a practical example? As I understand it, src here should be the name of an actual Python package. However, the whole example seems to be based on a src/ project layout. But src/ shouldn’t include a __init__.py file to make it a package, right?

So I assume a better example would be:

version = attr: yourpackage.VERSION
