- Installing and Using Setuptools
- ===============================
-
- .. contents:: **Table of Contents**
-
-
- -------------------------
- Installation Instructions
- -------------------------
-
- Windows
- =======
-
- Install setuptools using the provided ``.exe`` installer. If you've previously
- installed older versions of setuptools, please delete all ``setuptools*.egg``
- and ``setuptools.pth`` files from your system's ``site-packages`` directory
- (and any other ``sys.path`` directories) FIRST.
-
- If you are upgrading a previous version of setuptools that was installed using
- an ``.exe`` installer, please be sure to also *uninstall that older version*
- via your system's "Add/Remove Programs" feature, BEFORE installing the newer
- version.
-
- Once installation is complete, you will find an ``easy_install.exe`` program in
- your Python ``Scripts`` subdirectory. Be sure to add this directory to your
- ``PATH`` environment variable, if you haven't already done so.
-
-
- RPM-Based Systems
- =================
-
- Install setuptools using the provided source RPM. The included ``.spec`` file
- assumes you are installing using the default ``python`` executable, and is not
- specific to a particular Python version. The ``easy_install`` executable will
- be installed to a system ``bin`` directory such as ``/usr/bin``.
-
- If you wish to install to a location other than the default Python
- installation's default ``site-packages`` directory (and ``$prefix/bin`` for
- scripts), please use the ``.egg``-based installation approach described in the
- following section.
-
-
- Cygwin, Mac OS X, Linux, Other
- ==============================
-
- 1. Download the appropriate egg for your version of Python (e.g.
- ``setuptools-0.6c9-py2.4.egg``). Do NOT rename it.
-
- 2. Run it as if it were a shell script, e.g. ``sh setuptools-0.6c9-py2.4.egg``.
- Setuptools will install itself using the matching version of Python (e.g.
- ``python2.4``), and will place the ``easy_install`` executable in the
- default location for installing Python scripts (as determined by the
- standard distutils configuration files, or by the Python installation).
-
- If you want to install setuptools to somewhere other than ``site-packages`` or
- your default distutils installation locations for libraries and scripts, you
- may include EasyInstall command-line options such as ``--prefix``,
- ``--install-dir``, and so on, following the ``.egg`` filename on the same
- command line. For example::
-
- sh setuptools-0.6c9-py2.4.egg --prefix=~
-
- You can use ``--help`` to get a full options list, but we recommend consulting
- the `EasyInstall manual`_ for detailed instructions, especially `the section
- on custom installation locations`_.
-
- .. _EasyInstall manual: http://peak.telecommunity.com/DevCenter/EasyInstall
- .. _the section on custom installation locations: http://peak.telecommunity.com/DevCenter/EasyInstall#custom-installation-locations
-
-
- Cygwin Note
- -----------
-
- If you are trying to install setuptools for the **Windows** version of Python
- (as opposed to the Cygwin version that lives in ``/usr/bin``), you must make
- sure that an appropriate executable (``python2.3``, ``python2.4``, or
- ``python2.5``) is on your **Cygwin** ``PATH`` when invoking the egg. For
- example, doing the following at a Cygwin bash prompt will install setuptools
- for the **Windows** Python found at ``C:\\Python24``::
-
- ln -s /cygdrive/c/Python24/python.exe python2.4
- PATH=.:$PATH sh setuptools-0.6c9-py2.4.egg
- rm python2.4
-
-
- Downloads
- =========
-
- All setuptools downloads can be found at `the project's home page in the Python
- Package Index`_. Scroll to the very bottom of the page to find the links.
-
- .. _the project's home page in the Python Package Index: http://pypi.python.org/pypi/setuptools#files
-
- In addition to the PyPI downloads, the development version of ``setuptools``
- is available from the `Python SVN sandbox`_, and in-development versions of the
- `0.6 branch`_ are available as well.
-
- .. _0.6 branch: http://svn.python.org/projects/sandbox/branches/setuptools-0.6/#egg=setuptools-dev06

- Using Setuptools and EasyInstall
- --------------------------------
-
- Here are some of the available manuals, tutorials, and other resources for
- learning about Setuptools, Python Eggs, and EasyInstall:
-
- * `The EasyInstall user's guide and reference manual`_
- * `The setuptools Developer's Guide`_
- * `The pkg_resources API reference`_
- * `Package Compatibility Notes`_ (user-maintained)
- * `The Internal Structure of Python Eggs`_
-
- Questions, comments, and bug reports should be directed to the `distutils-sig
- mailing list`_. If you have written (or know of) any tutorials, documentation,
- plug-ins, or other resources for setuptools users, please let us know about
- them there, so this reference list can be updated. If you have working,
- *tested* patches to correct problems or add features, you may submit them to
- the `setuptools bug tracker`_.

- Credits
- -------
-
- * The original design for the ``.egg`` format and the ``pkg_resources`` API was
- co-created by Phillip Eby and Bob Ippolito. Bob also implemented the first
- version of ``pkg_resources``, and supplied the OS X operating system version
- compatibility algorithm.
-
- * Ian Bicking implemented many early "creature comfort" features of
- easy_install, including support for downloading via Sourceforge and
- Subversion repositories. Ian's comments on the Web-SIG about WSGI
- application deployment also inspired the concept of "entry points" in eggs,
- and he has given talks at PyCon and elsewhere to inform and educate the
- community about eggs and setuptools.
-
- * Jim Fulton contributed time and effort to build automated tests of various
- aspects of ``easy_install``, and supplied the doctests for the command-line
- ``.exe`` wrappers on Windows.
-
- * Phillip J. Eby is the principal author and maintainer of setuptools, and
- first proposed the idea of an importable binary distribution format for
- Python application plug-ins.
-
- * Significant parts of the implementation of setuptools were funded by the Open
- Source Applications Foundation, to provide a plug-in infrastructure for the
- Chandler PIM application. In addition, many OSAF staffers (such as Mike
- "Code Bear" Taylor) contributed their time and stress as guinea pigs for the
- use of eggs and setuptools, even before eggs were "cool". (Thanks, guys!)

-"""Package resource API
---------------------
-
-A resource is a logical file contained within a package, or a logical
-subdirectory thereof. The package resource API expects resource names
-to have their path parts separated with ``/``, *not* whatever the local
-path separator is. Do not use os.path operations to manipulate resource
-names being passed into the API.
-
-The package resource API is designed to work with normal filesystem packages,
-.egg files, and unpacked .egg files. It can also work in a limited way with
-.zip files and with custom PEP 302 loaders that support the ``get_data()``
-method.

- Finally, to handle miscellaneous cases, the strings "pre", "preview", and
- "rc" are treated as if they were "c", i.e. as though they were release
- candidates, and therefore are not as new as a version string that does not
- contain them, and "dev" is replaced with an '@' so that it sorts lower than

- """Distribution with support for features, tests, and package data
-
- This is an enhanced version of 'distutils.dist.Distribution' that
- effectively adds the following new optional keyword arguments to 'setup()':
-
- 'install_requires' -- a string or sequence of strings specifying project
- versions that the distribution requires when installed, in the format
- used by 'pkg_resources.require()'. They will be installed
- automatically when the package is installed. If you wish to use
- packages that are not available in PyPI, or want to give your users an
- alternate download location, you can add a 'find_links' option to the
- '[easy_install]' section of your project's 'setup.cfg' file, and then
- setuptools will scan the listed web pages for links that satisfy the
- requirements.
-
- 'extras_require' -- a dictionary mapping names of optional "extras" to the
- additional requirement(s) that using those extras incurs. For example,
- this::
-
- extras_require = dict(reST = ["docutils>=0.3", "reSTedit"])
-
- indicates that the distribution can optionally provide an extra
- capability called "reST", but it can only be used if docutils and
- reSTedit are installed. If the user installs your package using
- EasyInstall and requests one of your extras, the corresponding
- additional requirements will be installed if needed.
-
- 'features' -- a dictionary mapping option names to 'setuptools.Feature'
- objects. Features are a portion of the distribution that can be
- included or excluded based on user options, inter-feature dependencies,
- and availability on the current system. Excluded features are omitted
- from all setup commands, including source and binary distributions, so
- you can create multiple distributions from the same source tree.
- Feature names should be valid Python identifiers, except that they may
- contain the '-' (minus) sign. Features can be included or excluded
- via the command line options '--with-X' and '--without-X', where 'X' is
- the name of the feature. Whether a feature is included by default, and
- whether you are allowed to control this from the command line, is
- determined by the Feature object. See the 'Feature' class for more
- information.
-
- 'test_suite' -- the name of a test suite to run for the 'test' command.
- If the user runs 'python setup.py test', the package will be installed,
- and the named test suite will be run. The format is the same as
- would be used on a 'unittest.py' command line. That is, it is the
- dotted name of an object to import and call to generate a test suite.
-
- 'package_data' -- a dictionary mapping package names to lists of filenames
- or globs to use to find data files contained in the named packages.
- If the dictionary has filenames or globs listed under '""' (the empty
- string), those names will be searched for in every package, in addition
- to any names for the specific package. Data files found using these
- names/globs will be installed along with the package, in the same
- location as the package. Note that globs are allowed to reference
- the contents of non-package subdirectories, as long as you use '/' as
- a path separator. (Globs are automatically converted to
- platform-specific paths at runtime.)
-
- In addition to these new keywords, this class also has several new methods
- for manipulating the distribution's contents. For example, the 'include()'
- and 'exclude()' methods can be thought of as in-place add and subtract
- commands that add or remove packages, modules, extensions, and so on from
- the distribution. They are used by the feature subsystem to configure the
- distribution for the included and excluded features.

-
- 'standard' -- if true, the feature is included by default if it is
- available on the current system. Otherwise, the feature is only
- included if requested via a command line '--with-X' option, or if
- another included feature requires it. The default setting is 'False'.
-
- 'available' -- if true, the feature is available for installation on the
- current system. The default setting is 'True'.
-
- 'optional' -- if true, the feature's inclusion can be controlled from the
- command line, using the '--with-X' or '--without-X' options. If
- false, the feature's inclusion status is determined automatically,
- based on 'availabile', 'standard', and whether any other feature
- requires it. The default setting is 'True'.
-
- 'require_features' -- a string or sequence of strings naming features
- that should also be included if this feature is included. Defaults to
- empty list. May also contain 'Require' objects that should be
- added/removed from the distribution.
-
- 'remove' -- a string or list of strings naming packages to be removed
- from the distribution if this feature is *not* included. If the
- feature *is* included, this argument is ignored. This argument exists
- to support removing features that "crosscut" a distribution, such as
- defining a 'tests' feature that removes all the 'tests' subpackages
- provided by other features. The default for this argument is an empty
- list. (Note: the named package(s) or modules must exist in the base
- distribution when the 'setup()' function is initially called.)
-
- other keywords -- any other keyword arguments are saved, and passed to
- the distribution's 'include()' and 'exclude()' methods when the
- feature is included or excluded, respectively. So, for example, you
- could pass 'packages=["a","b"]' to cause packages 'a' and 'b' to be
- added or removed from the distribution as appropriate.
-
- A feature must include at least one 'requires', 'remove', or other
- keyword argument. Otherwise, it can't affect the distribution in any way.
- Note also that you can subclass 'Feature' to create your own specialized
- feature types that modify the distribution in other ways when included or
- excluded. See the docstrings for the various methods here for more detail.

+Summary: Download, build, install, upgrade, and uninstall Python packages -- easily! (zetuptoolz fork)
+Home-page: http://pypi.python.org/pypi/setuptools
+Author: Phillip J. Eby
+Author-email: distutils-sig@python.org
+License: PSF or ZPL
+Description: ======================
+ This is not Setuptools
+ ======================
+
+ This is the ``zetuptoolz`` fork of setuptools, which is used to install
+ `Tahoe-LAFS`_. It has a `darcs source repository`_ and `issue tracker`_.
+
+ For a list of differences between this fork and setuptools, see zetuptoolz.txt.
+
+ Note that, to avoid interfering with any setuptools installation, zetuptoolz
+ does not install a script called ``easy_install``. There is an ``easy_install_z``
+ script, but that is intended only for developers to test differences between
+ setuptools and zetuptoolz.
+
+ .. _Tahoe-LAFS: http://tahoe-lafs.org/
+ .. _darcs source repository: http://tahoe-lafs.org/source/zetuptoolz/trunk
+ .. _issue tracker: http://tahoe-lafs.org/trac/zetuptoolz
+
+
+ --------------------------------
+ Using Setuptools and EasyInstall
+ --------------------------------
+
+ Here are some of the available manuals, tutorials, and other resources for
+ learning about Setuptools, Python Eggs, and EasyInstall:
+
+ * `The EasyInstall user's guide and reference manual`_
+ * `The setuptools Developer's Guide`_
+ * `The pkg_resources API reference`_
+ * `Package Compatibility Notes`_ (user-maintained)
+ * `The Internal Structure of Python Eggs`_
+
+ Questions, comments, and bug reports should be directed to the `distutils-sig
+ mailing list`_. If you have written (or know of) any tutorials, documentation,
+ plug-ins, or other resources for setuptools users, please let us know about
+ them there, so this reference list can be updated. If you have working,
+ *tested* patches to correct problems or add features, you may submit them to
+ the `setuptools bug tracker`_.
+
+ .. _setuptools bug tracker: http://bugs.python.org/setuptools/
+ .. _Package Compatibility Notes: http://peak.telecommunity.com/DevCenter/PackageNotes
+ .. _The Internal Structure of Python Eggs: http://peak.telecommunity.com/DevCenter/EggFormats

+
+
+ -------
+ Credits
+ -------
+
+ * The original design for the ``.egg`` format and the ``pkg_resources`` API was
+ co-created by Phillip Eby and Bob Ippolito. Bob also implemented the first
+ version of ``pkg_resources``, and supplied the OS X operating system version
+ compatibility algorithm.
+
+ * Ian Bicking implemented many early "creature comfort" features of
+ easy_install, including support for downloading via Sourceforge and
+ Subversion repositories. Ian's comments on the Web-SIG about WSGI
+ application deployment also inspired the concept of "entry points" in eggs,
+ and he has given talks at PyCon and elsewhere to inform and educate the
+ community about eggs and setuptools.
+
+ * Jim Fulton contributed time and effort to build automated tests of various
+ aspects of ``easy_install``, and supplied the doctests for the command-line
+ ``.exe`` wrappers on Windows.
+
+ * Phillip J. Eby is the principal author and maintainer of setuptools, and
+ first proposed the idea of an importable binary distribution format for
+ Python application plug-ins.
+
+ * Significant parts of the implementation of setuptools were funded by the Open
+ Source Applications Foundation, to provide a plug-in infrastructure for the
+ Chandler PIM application. In addition, many OSAF staffers (such as Mike
+ "Code Bear" Taylor) contributed their time and stress as guinea pigs for the
+ use of eggs and setuptools, even before eggs were "cool". (Thanks, guys!)

+ "rc" are treated as if they were "c", i.e. as though they were release
+ candidates, and therefore are not as new as a version string that does not

+class Distribution(_Distribution):
+ """Distribution with support for features, tests, and package data
+
+ This is an enhanced version of 'distutils.dist.Distribution' that
+ effectively adds the following new optional keyword arguments to 'setup()':
+
+ 'install_requires' -- a string or sequence of strings specifying project
+ versions that the distribution requires when installed, in the format
+ used by 'pkg_resources.require()'. They will be installed
+ automatically when the package is installed. If you wish to use
+ packages that are not available in PyPI, or want to give your users an
+ alternate download location, you can add a 'find_links' option to the
+ '[easy_install]' section of your project's 'setup.cfg' file, and then
+ setuptools will scan the listed web pages for links that satisfy the
+ requirements.
+
+ 'extras_require' -- a dictionary mapping names of optional "extras" to the
+ additional requirement(s) that using those extras incurs. For example,
+ this::
+
+ extras_require = dict(reST = ["docutils>=0.3", "reSTedit"])
+
+ indicates that the distribution can optionally provide an extra
+ capability called "reST", but it can only be used if docutils and
+ reSTedit are installed. If the user installs your package using
+ EasyInstall and requests one of your extras, the corresponding
+ additional requirements will be installed if needed.
+
+ 'features' -- a dictionary mapping option names to 'setuptools.Feature'
+ objects. Features are a portion of the distribution that can be
+ included or excluded based on user options, inter-feature dependencies,
+ and availability on the current system. Excluded features are omitted
+ from all setup commands, including source and binary distributions, so
+ you can create multiple distributions from the same source tree.
+ Feature names should be valid Python identifiers, except that they may
+ contain the '-' (minus) sign. Features can be included or excluded
+ via the command line options '--with-X' and '--without-X', where 'X' is
+ the name of the feature. Whether a feature is included by default, and
+ whether you are allowed to control this from the command line, is
+ determined by the Feature object. See the 'Feature' class for more
+ information.
+
+ 'test_suite' -- the name of a test suite to run for the 'test' command.
+ If the user runs 'python setup.py test', the package will be installed,
+ and the named test suite will be run. The format is the same as
+ would be used on a 'unittest.py' command line. That is, it is the
+ dotted name of an object to import and call to generate a test suite.
+
+ 'package_data' -- a dictionary mapping package names to lists of filenames
+ or globs to use to find data files contained in the named packages.
+ If the dictionary has filenames or globs listed under '""' (the empty
+ string), those names will be searched for in every package, in addition
+ to any names for the specific package. Data files found using these
+ names/globs will be installed along with the package, in the same
+ location as the package. Note that globs are allowed to reference
+ the contents of non-package subdirectories, as long as you use '/' as
+ a path separator. (Globs are automatically converted to
+ platform-specific paths at runtime.)
+
+ In addition to these new keywords, this class also has several new methods
+ for manipulating the distribution's contents. For example, the 'include()'
+ and 'exclude()' methods can be thought of as in-place add and subtract
+ commands that add or remove packages, modules, extensions, and so on from
+ the distribution. They are used by the feature subsystem to configure the
+ distribution for the included and excluded features.

+differences:
+
+
+ * Zooko's patches for the following bugs and features have been applied:
+
+ <http://bugs.python.org/setuptools/issue17>
+ "easy_install will install a package that is already there"
+
+ <http://bugs.python.org/setuptools/issue54>
+ "be more like distutils with regard to --prefix="
+
+ <http://bugs.python.org/setuptools/issue53>
+ "respect the PYTHONPATH"
+ (Note: this patch does not work as intended when site.py has been modified.
+ This will be fixed in a future version.)
+
+
+ * The following patch to setuptools introduced bugs, and has been reverted
+ in zetuptoolz:
+
+ $ svn log -r 45514

+
+ Backport pkgutil, pydoc, and doctest from the 2.5 trunk to setuptools
+ 0.7 trunk. (Sideport?) Setuptools 0.7 will install these in place of
+ the 2.3/2.4 versions (at least of pydoc and doctest) to let them work
+ properly with eggs. pkg_resources now depends on the 2.5 pkgutil, which
+ is included here as _pkgutil, to work around the fact that some system
+ packagers will install setuptools without overriding the stdlib modules.
+ But users who install their own setuptools will get them, and the system
+ packaged people probably don't need them.
+ ------------------------------------------------------------------------
+
+
+ * If unpatched setuptools decides that it needs to change an existing site.py
+ file that appears not to have been written by it (because the file does not
+ start with "def __boot():"), it aborts the installation.
+ zetuptoolz leaves the file alone and outputs a warning, but continues with
+ the installation.
+
+
+ * The scripts written by zetuptoolz have the following extra line:
+
+ # generated by zetuptoolz <version number>
+
+ after the header.
+
+
+ * Windows-specific changes (native Python):
+
+ Python distributions may have command-line or GUI scripts.
+ On Windows, setuptools creates an executable wrapper to run each
+ script. zetuptools uses a different approach that does not require
+ an .exe wrapper. It writes approximately the same script file that
+ is used on other platforms, but with a .pyscript extension.
+ It also writes a shell-script wrapper (without any extension) that
+ is only used when the command is run from a Cygwin shell.
+
+ Some of the advantages of this approach are:
+
+ * Unicode arguments are preserved (although the program will
+ need to use some Windows-specific code to get at them in
+ current versions of Python);
+ * it works correctly on 64-bit Windows;
+ * the zetuptoolz distribution need not contain either any
+ binary executables, or any C code that needs to be compiled.
+
+ See setuptools\tests\win_script_wrapper.txt for further details.
+
+ Installing or building any distribution on Windows will automatically
+ associate .pyscript with the native Python interpreter for the current
+ user. It will also add .pyscript and .pyw to the PATHEXT variable for
+ the current user, which is needed to allow scripts to be run without
+ typing any extension.
+
+ There is an additional setup.py command that can be used to perform
+ these steps separately (which isn't normally needed, but might be
+ useful for debugging):
+
+ python setup.py scriptsetup
+
+ Adding the --allusers option, i.e.
+
+ python setup.py scriptsetup --allusers
+
+ will make the .pyscript association and changes to the PATHEXT variable
+ for all users of this Windows installation, except those that have it
+ overridden in their per-user environment. In this case setup.py must be
+ run with Administrator privileges, e.g. from a Command Prompt whose
+ shortcut has been set to run as Administrator.
