Collection of utilities for publishing packages on PyPI
Project description
Twine is a utility for publishing packages on PyPI.
Currently it only supports registering projects and uploading distributions.
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, while python setup.py upload only recently stopped using HTTP in Python 2.7.9+ and Python 3.2+. This means anytime you use python setup.py upload with an older Python version, you expose your username and password to being easily sniffed. Twine uses only verified TLS to upload to PyPI, protecting your credentials from theft.
Secondly, it allows you to precreate your distribution files. python setup.py upload only allows you to upload something that you’ve created in 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 <filename>.
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
$ pip install twine
Using Twine
Create some distributions in the normal way:
$ python setup.py sdist bdist_wheel
Upload with twine to Test PyPI and verify things look right. Twine will automatically prompt for your username and password:
$ twine upload --repository-url https://test.pypi.org/legacy/ dist/* username: ... password: ...
Upload to PyPI:
$ twine upload dist/*
Done!
More documentation on using twine to upload packages to PyPI is in the Python Packaging User Guide.
Keyring Support
Instead of typing in your password every time you upload a distribution, Twine allows you to store your username and password securely using keyring.
To use the keyring, you must first install the keyring packages:
On Windows and MacOS you just need to install keyring, for example, pip install --user keyring.
On Linux, in addition to the keyring package you also need to ensure the python3-dbus system package is installed. For example, apt install python3-dbus. See Keyring’s installation instructions for more details.
Once keyring is installed you can use the keyring program to set your username and password to use for each package index (repository) you want to upload to using Twine.
To set your username and password for test PyPI run the following command. keyring will prompt you for your password:
$ keyring set https://test.pypi.org/legacy/ your-username
# or
$ python3 -m keyring set https://test.pypi.org/legacy/ your-username
To set your username and password for PyPI run this command, again, keyring will prompt for the password:
$ keyring set https://upload.pypi.org/legacy/ your-username
# or
$ python3 -m keyring set https://upload.pypi.org/legacy/ your-username
The next time you run twine it will prompt you for a username and will grab the appropriate password from the keyring.
Options
$ twine upload -h
usage: twine upload [-h] [-r REPOSITORY] [--repository-url REPOSITORY_URL]
[-s] [--sign-with SIGN_WITH] [-i IDENTITY] [-u USERNAME]
[-p PASSWORD] [-c COMMENT] [--config-file CONFIG_FILE]
[--skip-existing] [--cert path] [--client-cert path]
dist [dist ...]
positional arguments:
dist The distribution files to upload to the repository
(package index). Usually dist/* . May additionally
contain a .asc file to include an existing signature
with the file upload.
optional arguments:
-h, --help show this help message and exit
-r REPOSITORY, --repository REPOSITORY
The repository (package index) to upload the package
to. Should be a section in the config file (default:
pypi). (Can also be set via TWINE_REPOSITORY
environment variable.)
--repository-url REPOSITORY_URL
The repository (package index) URL to upload the
package to. This overrides --repository. (Can also be
set via TWINE_REPOSITORY_URL environment variable.)
-s, --sign Sign files to upload using GPG.
--sign-with SIGN_WITH
GPG program used to sign uploads (default: gpg).
-i IDENTITY, --identity IDENTITY
GPG identity used to sign files.
-u USERNAME, --username USERNAME
The username to authenticate to the repository
(package index) as. (Can also be set via
TWINE_USERNAME environment variable.)
-p PASSWORD, --password PASSWORD
The password to authenticate to the repository
(package index) with. (Can also be set via
TWINE_PASSWORD environment variable.)
-c COMMENT, --comment COMMENT
The comment to include with the distribution file.
--config-file CONFIG_FILE
The .pypirc config file to use.
--skip-existing Continue uploading files if one already exists. (Only
valid when uploading to PyPI. Other implementations
may not support this.)
--cert path Path to alternate CA bundle (can also be set via
TWINE_CERT environment variable).
--client-cert path Path to SSL client certificate, a single file
containing the private key and the certificate in PEM
format.
Twine also includes a register command.
For completeness, its usage:
$ twine register -h
usage: twine register [-h] -r REPOSITORY [--repository-url REPOSITORY_URL]
[-u USERNAME] [-p PASSWORD] [-c COMMENT]
[--config-file CONFIG_FILE] [--cert path]
[--client-cert path]
package
positional arguments:
package File from which we read the package metadata.
optional arguments:
-h, --help show this help message and exit
-r REPOSITORY, --repository REPOSITORY
The repository (package index) to register the package
to. Should be a section in the config file. (Can also
be set via TWINE_REPOSITORY environment variable.)
Initial package registration no longer necessary on
pypi.org:
https://packaging.python.org/guides/migrating-to-pypi-
org/
--repository-url REPOSITORY_URL
The repository (package index) URL to register the
package to. This overrides --repository. (Can also be
set via TWINE_REPOSITORY_URL environment variable.)
-u USERNAME, --username USERNAME
The username to authenticate to the repository
(package index) as. (Can also be set via
TWINE_USERNAME environment variable.)
-p PASSWORD, --password PASSWORD
The password to authenticate to the repository
(package index) with. (Can also be set via
TWINE_PASSWORD environment variable.)
-c COMMENT, --comment COMMENT
The comment to include with the distribution file.
--config-file CONFIG_FILE
The .pypirc config file to use.
--cert path Path to alternate CA bundle (can also be set via
TWINE_CERT environment variable).
--client-cert path Path to SSL client certificate, a single file
containing the private key and the certificate in PEM
format.
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, such as a CI/build server, for example.
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.
