pypiserver is a minimal PyPI compatible server. It can be used to
serve a set of packages and eggs to easy_install or pip.

Installation and Usage/Quickstart
=================================
pypiserver will work with python 2.5, 2.6 and 2.7. Python 3 support
has been added with version 0.4.0.

Run the following commands to get your PyPI server up and running::

  pip install pypiserver
  mkdir ~/packages
  # copy some source packages or eggs to this directory
  pypi-server -p 8080 ~/packages
  pip install -i http://localhost:8080/simple/ ...

Alternative Installation as standalone script
=============================================
The git repository contains a 'pypi-server-standalone.py' script,
which is a single python file ready to be executed without any other
dependencies.

This does *not* work when you're using Python 3.0 or up!

Run the following commands to download the script with wget::

  wget https://raw.github.com/schmir/pypiserver/standalone/pypi-server-standalone.py
  chmod +x pypi-server-standalone.py

or with curl::

  curl -O https://raw.github.com/schmir/pypiserver/standalone/pypi-server-standalone.py
  chmod +x pypi-server-standalone.py

The server can then be started with::

  ./pypi-server-standalone.py

Feel free to rename the script and move it into your $PATH.


Detailed Usage
=================================
pypi-server -h will print a detailed usage message::

  pypi-server [OPTIONS] [PACKAGES_DIRECTORY]
    start PyPI compatible package server serving packages from
    PACKAGES_DIRECTORY. If PACKAGES_DIRECTORY is not given on the
    command line, it uses the default ~/packages.  pypiserver scans this
    directory recursively for packages. It skips packages and
    directories starting with a dot.

  pypi-server understands the following options:

    -p PORT, --port PORT
      listen on port PORT (default: 8080)

    -i INTERFACE, --interface INTERFACE
      listen on interface INTERFACE (default: 0.0.0.0, any interface)

    --disable-fallback
      disable redirect to real PyPI index for packages not found in the
      local index

    --server METHOD
      use METHOD to run the server. Valid values include paste,
      cherrypy, twisted, gunicorn, gevent, wsgiref, auto. The
      default is to use "auto" which chooses one of paste, cherrypy,
      twisted or wsgiref.

    -r PACKAGES_DIRECTORY, --root PACKAGES_DIRECTORY
      [deprecated] serve packages from PACKAGES_DIRECTORY

  pypi-server -h
  pypi-server --help
    show this help message

  pypi-server --version
    show pypi-server's version

  pypi-server -U [OPTIONS] [PACKAGES_DIRECTORY]
    update packages in PACKAGES_DIRECTORY. This command searches
    pypi.python.org for updates and shows a pip command line which
    updates the package.

  The following additional options can be specified with -U:

    -x
      execute the pip commands instead of only showing them

    -d DOWNLOAD_DIRECTORY
      download package updates to this directory. The default is to use
      the directory which contains the latest version of the package to
      be updated.

    -u
      allow updating to unstable version (alpha, beta, rc, dev versions)

  Visit http://pypi.python.org/pypi/pypiserver for more information.



Configuring pip/easy_install
============================
Always specifying the the pypi url on the command line is a bit
cumbersome. Since pypi-server redirects pip/easy_install to the
pypi.python.org index if it doesn't have a requested package, it's a
good idea to configure them to always use your local pypi index.

pip
-----
For pip this can be done by setting the environment variable
PIP_INDEX_URL in your .bashrc/.profile/.zshrc::

  export PIP_INDEX_URL=http://localhost:8080/simple/

or by adding the following lines to ~/.pip/pip.conf::

  [global]
  index-url = http://localhost:8080/simple/

easy_install
------------
For easy_install it can be configured with the following setting in
~/.pydistutils.cfg::

  [easy_install]
  index_url = http://localhost:8080/simple/

Managing the package directory
==============================
pypi-server's -U option makes it possible to search for updates of
available packages. It scans the package directory for available
packages and searches on pypi.python.org for updates. Without further
options 'pypi-server -U' will just print a list of commands which must
be run in order to get the latest version of each package. Output
looks like::

  checking 82 packages for newer version

  .e......u.........e....e.....u...u....e.
  e......u...ee.ee.e......u.........ee....
  ..

  no releases found on pypi for PyXML, Pymacs, _sqlite3, bbutils, isoap, mercurial, pil, pycdb, ropemode, schmir, setuptools, unbuffered

  # update Twisted from 11.0.0 to 11.1.0
  pip -q install -i http://pypi.python.org/simple -d /home/ralf/packages Twisted==11.1.0

  # update pytest from 2.1.3 to 2.2.0
  pip -q install -i http://pypi.python.org/simple -d /home/ralf/packages pytest==2.2.0

  # update zope.interface from 3.6.3 to 3.8.0
  pip -q install -i http://pypi.python.org/simple -d /home/ralf/packages zope.interface==3.8.0

  # update pytest-xdist from 1.6 to 1.7
  pip -q install -i http://pypi.python.org/simple -d /home/ralf/packages pytest-xdist==1.7

  # update pyOpenSSL from 0.10 to 0.13
  pip -q install -i http://pypi.python.org/simple -d /home/ralf/packages pyOpenSSL==0.13

It first prints for each package a single character after checking the
available versions on pypi. A dot means the package is up-to-date, 'u'
means the package can be updated and 'e' means the list of releases on
pypi is empty. After that it show a pip command line which can be used
to update a one package. Either copy and paste that or run
"pypi-server -Ux" in order to really execute those commands. You need
to have pip installed for that to work however.

Specifying an additional '-u' option will also allow alpha, beta and
release candidates to be downloaded. Without this option these
releases won't be considered.


Optional dependencies
=====================
- pypiserver ships with it's own copy of bottle. It's possible to use
  bottle with different wsgi servers. pypiserver chooses any of the
  following paste, cherrypy, twisted, wsgiref (part of python) if
  available.

Source
===========
Source releases can be downloaded from
http://pypi.python.org/pypi/pypiserver

https://github.com/schmir/pypiserver carries a git repository of the
in-development version.

Use::

  git clone https://github.com/schmir/pypiserver.git

to create a copy of the repository, then::

  git pull

inside the copy to receive the latest version.


Bugs
=============
pypiserver does not implement the full API as seen on PyPI_. It
implements just enough to make easy_install and pip install work.

The following limitations are known:

- pypiserver doesn't support uploading files. One might also consider
  that a feature. scp provides a nice workaround.
- pypiserver doesn't implement the XMLRPC interface: pip search
  will not work.
- pypiserver doesn't implement the json based '/pypi' interface. pyg_
  uses that and will not work.

Please use github's bugtracker
https://github.com/schmir/pypiserver/issues if you find any other
bugs.
