"""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' **deprecated** -- 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.

A subset of the distribution that can be excluded if unneeded/wanted
|
||
|
|
|
||
|
|
Features are created using these keyword arguments:
|
||
|
|
|
||
|
|
'description' -- a short, human readable description of the feature, to
|
||
|
|
be used in error messages, and option help messages.
|
||
|
|
|
||
|
|
'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.
|
||
|
|
Aside from the methods, the only feature attributes that distributions look
|
||
|
|
at are 'description' and 'optional'.
