***************************************
Uploading Packages to the Package Index
***************************************
.. versionadded:: 2.5
The Python Package Index (PyPI) not only stores the package info, but also the
package data if the author of the package wishes to. The distutils command
:command:`upload` pushes the distribution files to PyPI.
The command is invoked immediately after building one or more distribution
files. For example, the command ::
python setup.py sdist bdist_wininst upload
2007-08-15 11:28:01 -03:00
will cause the source distribution and the Windows installer to be uploaded to
PyPI. Note that these will be uploaded even if they are built using an earlier
invocation of :file:`setup.py`, but that only distributions named on the command
line for the invocation including the :command:`upload` command are uploaded.
The :command:`upload` command uses the username, password, and repository URL
from the :file:`$HOME/.pypirc` file (see section :ref:`pypirc` for more on this
file). If a :command:`register` command was previously called in the same command,
and if the password was entered in the prompt, :command:`upload` will reuse the
entered password. This is useful if you do not want to store a clear text
password in the :file:`$HOME/.pypirc` file.

You can specify another PyPI server with the :option:`--repository=*url*` option::
python setup.py sdist bdist_wininst upload -r http://example.com/pypi
See section :ref:`pypirc` for more on defining several servers.
2007-08-15 11:28:01 -03:00
You can use the :option:`--sign` option to tell :command:`upload` to sign each
uploaded file using GPG (GNU Privacy Guard). The :program:`gpg` program must
be available for execution on the system :envvar:`PATH`. You can also specify
which key to use for signing using the :option:`--identity=*name*` option.

Other :command:`upload` options include :option:`--repository=<url>` or
:option:`--repository=<section>` where *url* is the url of the server and
*section* the name of the section in :file:`$HOME/.pypirc`, and

:option:`--show-response` (which displays the full response text from the PyPI
server for help in debugging upload problems).

PyPI package display
====================
The ``long_description`` field plays a special role at PyPI. It is used by
the server to display a home page for the registered package.
If you use the `reStructuredText <http://docutils.sourceforge.net/rst.html>`_
syntax for this field, PyPI will parse it and display an HTML output for
the package home page.
The ``long_description`` field can be attached to a text file located
in the package::
from distutils.core import setup
setup(name='Distutils',
long_description=open('README.txt'))
2010-03-12 06:02:03 -04:00
In that case, :file:`README.txt` is a regular reStructuredText text file located
in the root of the package besides :file:`setup.py`.
2009-02-26 22:14:35 -04:00
To prevent registering broken reStructuredText content, you can use the
2010-03-12 06:02:03 -04:00
:program:`rst2html` program that is provided by the :mod:`docutils` package
2009-02-26 22:14:35 -04:00
and check the ``long_description`` from the command line::
$ python setup.py --long-description | rst2html.py > output.html
2010-03-12 06:02:03 -04:00
:mod:`docutils` will display a warning if there's something wrong with your syntax.
