.. twine documentation master file, originally created by sphinx-quickstart on Tue Aug 13 11:51:54 2013. You can adapt this file completely to your liking, but it should at least contain the root `toctree` directive. .. toctree:: :hidden: :maxdepth: 3 changelog contributing Code of Conduct PyPI Project GitHub Repository Python Packaging Tutorial Twine ===== Twine is a utility for `publishing`_ Python packages to `PyPI`_ and other `repositories`_. It provides build system independent uploads of source and binary `distribution artifacts `_ for both new and existing `projects`_. Why Should I Use This? ---------------------- The goal of Twine is to improve PyPI interaction by improving security and testability. The biggest reason to use Twine is that it securely authenticates you to PyPI over HTTPS using a verified connection, regardless of the underlying Python version. Meanwhile, ``python setup.py upload`` will only work correctly and securely if your build system, Python version, and underlying operating system are configured properly. Secondly, Twine encourages you to build your distribution files. ``python setup.py upload`` only allows you to upload a package as a final step after building with ``distutils`` or ``setuptools``, within the same command invocation. This means that you cannot test the exact file you're going to upload to PyPI to ensure that it works before uploading it. Finally, Twine allows you to pre-sign your files and pass the ``.asc`` files into the command line invocation (``twine upload myproject-1.0.1.tar.gz myproject-1.0.1.tar.gz.asc``). This enables you to be assured that you're typing your ``gpg`` passphrase into ``gpg`` itself and not anything else, since *you* will be the one directly executing ``gpg --detach-sign -a ``. Features -------- - Verified HTTPS connections - Uploading doesn't require executing ``setup.py`` - Uploading files that have already been created, allowing testing of distributions before release - Supports uploading any packaging format (including `wheels`_) Installation ------------ .. code-block:: bash pip install twine Using Twine ----------- 1. Create some distributions in the normal way: .. code-block:: bash python -m build 2. Upload to `Test PyPI`_ and verify things look right: .. code-block:: bash twine upload -r testpypi dist/* Twine will prompt for your username and password. 3. Upload to `PyPI`_: .. code-block:: bash twine upload dist/* 4. Done! .. _entering-credentials: .. note:: Like many other command line tools, Twine does not show any characters when you enter your password. If you're using Windows and trying to paste your username, password, or token in the Command Prompt or PowerShell, ``Ctrl-V`` and ``Shift+Insert`` won't work. Instead, you can use "Edit > Paste" from the window menu, or enable "Use Ctrl+Shift+C/V as Copy/Paste" in "Properties". This is a `known issue `_ with Python's ``getpass`` module. More documentation on using Twine to upload packages to PyPI is in the `Python Packaging User Guide`_. Commands -------- ``twine upload`` ^^^^^^^^^^^^^^^^ Uploads one or more distributions to a repository. .. program-output:: twine upload -h ``twine check`` ^^^^^^^^^^^^^^^ Checks whether your distribution's long description will render correctly on PyPI. .. program-output:: twine check -h ``twine register`` ^^^^^^^^^^^^^^^^^^ Pre-register a name with a repository before uploading a distribution. .. warning:: Pre-registration is `not supported on PyPI`_, so the ``register`` command is only necessary if you are using a different repository that requires it. See `issue #1627 on Warehouse`_ (the software running on PyPI) for more details. .. program-output:: twine register -h Configuration ------------- Twine can read repository configuration from a ``.pypirc`` file, either in your home directory, or provided with the ``--config-file`` option. For details on writing and using ``.pypirc``, see the `specification `_ in the Python Packaging User Guide. Environment Variables ^^^^^^^^^^^^^^^^^^^^^ Twine also supports configuration via environment variables. Options passed on the command line will take precedence over options set via environment variables. Definition via environment variable is helpful in environments where it is not convenient to create a ``.pypirc`` file (for example, on a CI/build server). * ``TWINE_USERNAME`` - the username to use for authentication to the repository. * ``TWINE_PASSWORD`` - the password to use for authentication to the repository. * ``TWINE_REPOSITORY`` - the repository configuration, either defined as a section in ``.pypirc`` or provided as a full URL. * ``TWINE_REPOSITORY_URL`` - the repository URL to use. * ``TWINE_CERT`` - custom CA certificate to use for repositories with self-signed or untrusted certificates. * ``TWINE_NON_INTERACTIVE`` - Do not interactively prompt for username/password if the required credentials are missing. Proxy Support ^^^^^^^^^^^^^ Twine can be configured to use a proxy by setting environment variables. For example, to use a proxy for just the ``twine`` command, without ``export``-ing it for other tools: .. code-block:: bash HTTPS_PROXY=socks5://user:pass@host:port twine upload dist/* For more information, see the Requests documentation on :ref:`requests:proxies` and :ref:`requests:socks`, and `an in-depth article about proxy environment variables `_. Keyring Support --------------- Instead of typing in your password every time you upload a distribution, Twine allows storing a username and password securely using `keyring`_. Keyring is installed with Twine but for some systems (Linux mainly) may require `additional installation steps`_. Once Twine is installed, use the ``keyring`` program to set a username and password to use for each repository to which you may upload. For example, to set a username and password for PyPI: .. code-block:: bash keyring set https://upload.pypi.org/legacy/ your-username and enter the password when prompted. For a different repository, replace the URL with the relevant repository URL. For example, for Test PyPI, use ``https://test.pypi.org/legacy/``. The next time you run ``twine``, it will prompt you for a username, and then get the appropriate password from Keyring. .. note:: If you are using Linux in a headless environment (such as on a server) you'll need to do some additional steps to ensure that Keyring can store secrets securely. See `Using Keyring on headless systems`_. Disabling Keyring ^^^^^^^^^^^^^^^^^ In most cases, simply not setting a password with ``keyring`` will allow Twine to fall back to prompting for a password. In some cases, the presence of Keyring will cause unexpected or undesirable prompts from the backing system. In these cases, it may be desirable to disable Keyring altogether. To disable Keyring, run: .. code-block:: bash keyring --disable See `Twine issue #338`_ for discussion and background. .. _`publishing`: https://packaging.python.org/tutorials/packaging-projects/ .. _`PyPI`: https://pypi.org .. _`Test PyPI`: https://packaging.python.org/guides/using-testpypi/ .. _`pypirc`: https://packaging.python.org/specifications/pypirc/ .. _`Python Packaging User Guide`: https://packaging.python.org/tutorials/packaging-projects/ .. _`keyring`: https://pypi.org/project/keyring/ .. _`Using Keyring on headless systems`: https://keyring.readthedocs.io/en/latest/#using-keyring-on-headless-linux-systems .. _`additional installation steps`: https://pypi.org/project/keyring/#installation-linux .. _`developer documentation`: https://twine.readthedocs.io/en/latest/contributing.html .. _`projects`: https://packaging.python.org/glossary/#term-Project .. _`distributions`: https://packaging.python.org/glossary/#term-Distribution-Package .. _`repositories`: https://packaging.python.org/glossary/#term-Package-Index .. _`PSF Code of Conduct`: https://github.com/pypa/.github/blob/main/CODE_OF_CONDUCT.md .. _`Warehouse`: https://github.com/pypa/warehouse .. _`wheels`: https://packaging.python.org/glossary/#term-Wheel .. _`not supported on PyPI`: https://packaging.python.org/guides/migrating-to-pypi-org/#registering-package-names-metadata .. _`issue #1627 on Warehouse`: https://github.com/pypa/warehouse/issues/1627 .. _`Twine issue #338`: https://github.com/pypa/twine/issues/338
