package-index 1.0.0b0

Dataclasses API for PyPI and other warehouses.

package-index

Check version of a Python module.

Queries PyPI and looks for the <module>.__version__ among all available versions. Raises an error if the version already exists.

Comes in handy in CI to remember changing library version.

For more on Python module versioning check out PEP-440.

Installation

Available from PyPI:

pip install package-index

Module Example

With a <module> present on PyPI and <module>.py in current directory:

__version__ = '7.7.7'

...

Simply run:

package-index <module>

If 7.7.7 version of <module> is on PyPI already you’ll get a VersionExists error:

Traceback (most recent call last):
  File "./package-index", line 86, in <module>
    main(sys.argv[1:])
  File "./package-index", line 82, in main
    check_unique(name, version)
  File "./package-index", line 28, in check_unique
    raise VersionExists(name, version)
__main__.VersionExists: Package "<module>" with version "7.7.7" already exists on PyPI.
Change the "<module>.__version__" to fix this error.

Package Example

Packages work in the same way as modules except __version__ is defined in <module>/__init__.py
