"""Distribution with support for 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.
|
|
|
|
'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.
