Test “Installation”

$ python -m pip install --editable ~/work/2022-11-07/
... yadda ...
  • Actually, not an installation

  • Creates links to source package

  • Can use the package as if it were installed

  • Source code is still editable

  • very helpful

  • ⟶ don’t need to set $PYTHONPATH into src/

Source Distribution

$ cd ~/work/2022-11-07/
$ python setup.py sdist
... yadda ...

Manifest

  • A file MANIFEST.in that contains all that need packaging

  • Written manually by default

  • Tool support: check-manifest

    $ python -m pip install check-manifest
    
  • Create (and add) MANIFEST.in

    $ check-manifest --create
    $ git add MANIFEST.in
    

Packaging

$ python setup.py bdist_wheel sdist
... yadda ...
$ ls -l dist/
