----------------- Command Reference ----------------- .. _alias: ``alias`` - Define shortcuts for commonly used commands ======================================================= Sometimes, you need to use the same commands over and over, but you can't necessarily set them as defaults. For example, if you produce both development snapshot releases and "stable" releases of a project, you may want to put the distributions in different places, or use different ``egg_info`` tagging options, etc. In these cases, it doesn't make sense to set the options in a distutils configuration file, because the values of the options changed based on what you're trying to do. Setuptools therefore allows you to define "aliases" - shortcut names for an arbitrary string of commands and options, using ``setup.py alias aliasname expansion``, where aliasname is the name of the new alias, and the remainder of the command line supplies its expansion. For example, this command defines a sitewide alias called "daily", that sets various ``egg_info`` tagging options:: setup.py alias --global-config daily egg_info --tag-build=development Once the alias is defined, it can then be used with other setup commands, e.g.:: setup.py daily bdist_egg # generate a daily-build .egg file setup.py daily sdist # generate a daily-build source distro setup.py daily sdist bdist_egg # generate both The above commands are interpreted as if the word ``daily`` were replaced with ``egg_info --tag-build=development``. Note that setuptools will expand each alias *at most once* in a given command line. This serves two purposes. First, if you accidentally create an alias loop, it will have no effect; you'll instead get an error message about an unknown command. Second, it allows you to define an alias for a command, that uses that command. For example, this (project-local) alias:: setup.py alias bdist_egg bdist_egg rotate -k1 -m.egg redefines the ``bdist_egg`` command so that it always runs the ``rotate`` command afterwards to delete all but the newest egg file. It doesn't loop indefinitely on ``bdist_egg`` because the alias is only expanded once when used. You can remove a defined alias with the ``--remove`` (or ``-r``) option, e.g.:: setup.py alias --global-config --remove daily would delete the "daily" alias we defined above. Aliases can be defined on a project-specific, per-user, or sitewide basis. The default is to define or remove a project-specific alias, but you can use any of the `configuration file options`_ (listed under the `saveopts`_ command, below) to determine which distutils configuration file an aliases will be added to (or removed from). Note that if you omit the "expansion" argument to the ``alias`` command, you'll get output showing that alias' current definition (and what configuration file it's defined in). If you omit the alias name as well, you'll get a listing of all current aliases along with their configuration file locations. ``bdist_egg`` - Create a Python Egg for the project =================================================== .. warning:: **eggs** are deprecated in favor of wheels, and not supported by pip. This command generates a Python Egg (``.egg`` file) for the project. Python Eggs are the preferred binary distribution format for EasyInstall, because they are cross-platform (for "pure" packages), directly importable, and contain project metadata including scripts and information about the project's dependencies. They can be simply downloaded and added to ``sys.path`` directly, or they can be placed in a directory on ``sys.path`` and then automatically discovered by the egg runtime system. This command runs the `egg_info`_ command (if it hasn't already run) to update the project's metadata (``.egg-info``) directory. If you have added any extra metadata files to the ``.egg-info`` directory, those files will be included in the new egg file's metadata directory, for use by the egg runtime system or by any applications or frameworks that use that metadata. You won't usually need to specify any special options for this command; just use ``bdist_egg`` and you're done. But there are a few options that may be occasionally useful: ``--dist-dir=DIR, -d DIR`` Set the directory where the ``.egg`` file will be placed. If you don't supply this, then the ``--dist-dir`` setting of the ``bdist`` command will be used, which is usually a directory named ``dist`` in the project directory. ``--plat-name=PLATFORM, -p PLATFORM`` Set the platform name string that will be embedded in the egg's filename (assuming the egg contains C extensions). This can be used to override the distutils default platform name with something more meaningful. Keep in mind, however, that the egg runtime system expects to see eggs with distutils platform names, so it may ignore or reject eggs with non-standard platform names. Similarly, the EasyInstall program may ignore them when searching web pages for download links. However, if you are cross-compiling or doing some other unusual things, you might find a use for this option. ``--exclude-source-files`` Don't include any modules' ``.py`` files in the egg, just compiled Python, C, and data files. (Note that this doesn't affect any ``.py`` files in the EGG-INFO directory or its subdirectories, since for example there may be scripts with a ``.py`` extension which must still be retained.) We don't recommend that you use this option except for packages that are being bundled for proprietary end-user applications, or for "embedded" scenarios where space is at an absolute premium. On the other hand, if your package is going to be installed and used in compressed form, you might as well exclude the source because Python's ``traceback`` module doesn't currently understand how to display zipped source code anyway, or how to deal with files that are in a different place from where their code was compiled. There are also some options you will probably never need, but which are there because they were copied from similar ``bdist`` commands used as an example for creating this one. They may be useful for testing and debugging, however, which is why we kept them: ``--keep-temp, -k`` Keep the contents of the ``--bdist-dir`` tree around after creating the ``.egg`` file. ``--bdist-dir=DIR, -b DIR`` Set the temporary directory for creating the distribution. The entire contents of this directory are zipped to create the ``.egg`` file, after running various installation commands to copy the package's modules, data, and extensions here. ``--skip-build`` Skip doing any "build" commands; just go straight to the install-and-compress phases. .. _develop: ``develop`` - Deploy the project source in "Development Mode" ============================================================= This command allows you to deploy your project's source for use in one or more "staging areas" where it will be available for importing. This deployment is done in such a way that changes to the project source are immediately available in the staging area(s), without needing to run a build or install step after each change. The ``develop`` command works by creating an ``.egg-link`` file (named for the project) in the given staging area. If the staging area is Python's ``site-packages`` directory, it also updates an ``easy-install.pth`` file so that the project is on ``sys.path`` by default for all programs run using that Python installation. The ``develop`` command also installs wrapper scripts in the staging area (or a separate directory, as specified) that will ensure the project's dependencies are available on ``sys.path`` before running the project's source scripts. And, it ensures that any missing project dependencies are available in the staging area, by downloading and installing them if necessary. Last, but not least, the ``develop`` command invokes the ``build_ext -i`` command to ensure any C extensions in the project have been built and are up-to-date, and the ``egg_info`` command to ensure the project's metadata is updated (so that the runtime and wrappers know what the project's dependencies are). If you make any changes to the project's setup script or C extensions, you should rerun the ``develop`` command against all relevant staging areas to keep the project's scripts, metadata and extensions up-to-date. Most other kinds of changes to your project should not require any build operations or rerunning ``develop``, but keep in mind that even minor changes to the setup script (e.g. changing an entry point definition) require you to re-run the ``develop`` or ``test`` commands to keep the distribution updated. Here are some of the options that the ``develop`` command accepts. Note that they affect the project's dependencies as well as the project itself, so if you have dependencies that need to be installed and you use ``--exclude-scripts`` (for example), the dependencies' scripts will not be installed either! For this reason, you may want to use pip to install the project's dependencies before using the ``develop`` command, if you need finer control over the installation options for dependencies. ``--uninstall, -u`` Un-deploy the current project. You may use the ``--install-dir`` or ``-d`` option to designate the staging area. The created ``.egg-link`` file will be removed, if present and it is still pointing to the project directory. The project directory will be removed from ``easy-install.pth`` if the staging area is Python's ``site-packages`` directory. Note that this option currently does *not* uninstall script wrappers! You must uninstall them yourself, or overwrite them by using pip to install a different version of the package. You can also avoid installing script wrappers in the first place, if you use the ``--exclude-scripts`` (aka ``-x``) option when you run ``develop`` to deploy the project. ``--multi-version, -m`` "Multi-version" mode. Specifying this option prevents ``develop`` from adding an ``easy-install.pth`` entry for the project(s) being deployed, and if an entry for any version of a project already exists, the entry will be removed upon successful deployment. In multi-version mode, no specific version of the package is available for importing, unless you use ``pkg_resources.require()`` to put it on ``sys.path``, or you are running a wrapper script generated by ``setuptools``. (In which case the wrapper script calls ``require()`` for you.) Note that if you install to a directory other than ``site-packages``, this option is automatically in effect, because ``.pth`` files can only be used in ``site-packages`` (at least in Python 2.3 and 2.4). So, if you use the ``--install-dir`` or ``-d`` option (or they are set via configuration file(s)) your project and its dependencies will be deployed in multi- version mode. ``--install-dir=DIR, -d DIR`` Set the installation directory (staging area). If this option is not directly specified on the command line or in a distutils configuration file, the distutils default installation location is used. Normally, this will be the ``site-packages`` directory, but if you are using distutils configuration files, setting things like ``prefix`` or ``install_lib``, then those settings are taken into account when computing the default staging area. ``--script-dir=DIR, -s DIR`` Set the script installation directory. If you don't supply this option (via the command line or a configuration file), but you *have* supplied an ``--install-dir`` (via command line or config file), then this option defaults to the same directory, so that the scripts will be able to find their associated package installation. Otherwise, this setting defaults to the location where the distutils would normally install scripts, taking any distutils configuration file settings into account. ``--exclude-scripts, -x`` Don't deploy script wrappers. This is useful if you don't want to disturb existing versions of the scripts in the staging area. ``--always-copy, -a`` Copy all needed distributions to the staging area, even if they are already present in another directory on ``sys.path``. By default, if a requirement can be met using a distribution that is already available in a directory on ``sys.path``, it will not be copied to the staging area. ``--egg-path=DIR`` Force the generated ``.egg-link`` file to use a specified relative path to the source directory. This can be useful in circumstances where your installation directory is being shared by code running under multiple platforms (e.g. Mac and Windows) which have different absolute locations for the code under development, but the same *relative* locations with respect to the installation directory. If you use this option when installing, you must supply the same relative path when uninstalling. In addition to the above options, the ``develop`` command also accepts all of the same options accepted by ``easy_install``. If you've configured any ``easy_install`` settings in your ``setup.cfg`` (or other distutils config files), the ``develop`` command will use them as defaults, unless you override them in a ``[develop]`` section or on the command line. .. _egg_info: ``egg_info`` - Create egg metadata and set build tags ===================================================== This command performs two operations: it updates a project's ``.egg-info`` metadata directory (used by the ``bdist_egg``, ``develop``, and ``test`` commands), and it allows you to temporarily change a project's version string, to support "daily builds" or "snapshot" releases. It is run automatically by the ``sdist``, ``bdist_egg``, ``develop``, and ``test`` commands in order to update the project's metadata, but you can also specify it explicitly in order to temporarily change the project's version string while executing other commands. (It also generates the ``.egg-info/SOURCES.txt`` manifest file, which is used when you are building source distributions.) In addition to writing the core egg metadata defined by ``setuptools`` and required by ``pkg_resources``, this command can be extended to write other metadata files as well, by defining entry points in the ``egg_info.writers`` group. See the section on :ref:`Adding new EGG-INFO Files` below for more details. Note that using additional metadata writers may require you to include a ``setup_requires`` argument to ``setup()`` in order to ensure that the desired writers are available on ``sys.path``. Release Tagging Options ----------------------- The following options can be used to modify the project's version string for all remaining commands on the setup command line. The options are processed in the order shown, so if you use more than one, the requested tags will be added in the following order: ``--tag-build=NAME, -b NAME`` Append NAME to the project's version string. Due to the way setuptools processes "pre-release" version suffixes beginning with the letters "a" through "e" (like "alpha", "beta", and "candidate"), you will usually want to use a tag like ".build" or ".dev", as this will cause the version number to be considered *lower* than the project's default version. (If you want to make the version number *higher* than the default version, you can always leave off --tag-build and then use one or both of the following options.) If you have a default build tag set in your ``setup.cfg``, you can suppress it on the command line using ``-b ""`` or ``--tag-build=""`` as an argument to the ``egg_info`` command. ``--tag-date, -d`` Add a date stamp of the form "-YYYYMMDD" (e.g. "-20050528") to the project's version number. ``--no-date, -D`` Don't include a date stamp in the version number. This option is included so you can override a default setting in ``setup.cfg``. (Note: Because these options modify the version number used for source and binary distributions of your project, you should first make sure that you know how the resulting version numbers will be interpreted by automated tools like pip. See the section above on :ref:`Specifying Your Project's Version` for an explanation of pre- and post-release tags, as well as tips on how to choose and verify a versioning scheme for your project.) For advanced uses, there is one other option that can be set, to change the location of the project's ``.egg-info`` directory. Commands that need to find the project's source directory or metadata should get it from this setting: Other ``egg_info`` Options -------------------------- ``--egg-base=SOURCEDIR, -e SOURCEDIR`` Specify the directory that should contain the .egg-info directory. This should normally be the root of your project's source tree (which is not necessarily the same as your project directory; some projects use a ``src`` or ``lib`` subdirectory as the source root). You should not normally need to specify this directory, as it is normally determined from the ``package_dir`` argument to the ``setup()`` function, if any. If there is no ``package_dir`` set, this option defaults to the current directory. ``egg_info`` Examples --------------------- Creating a dated "nightly build" snapshot egg:: setup.py egg_info --tag-date --tag-build=DEV bdist_egg Creating a release with no version tags, even if some default tags are specified in ``setup.cfg``:: setup.py egg_info -RDb "" sdist bdist_egg (Notice that ``egg_info`` must always appear on the command line *before* any commands that you want the version changes to apply to.) .. _rotate: ``rotate`` - Delete outdated distribution files =============================================== As you develop new versions of your project, your distribution (``dist``) directory will gradually fill up with older source and/or binary distribution files. The ``rotate`` command lets you automatically clean these up, keeping only the N most-recently modified files matching a given pattern. ``--match=PATTERNLIST, -m PATTERNLIST`` Comma-separated list of glob patterns to match. This option is *required*. The project name and ``-*`` is prepended to the supplied patterns, in order to match only distributions belonging to the current project (in case you have a shared distribution directory for multiple projects). Typically, you will use a glob pattern like ``.zip`` or ``.egg`` to match files of the specified type. Note that each supplied pattern is treated as a distinct group of files for purposes of selecting files to delete. ``--keep=COUNT, -k COUNT`` Number of matching distributions to keep. For each group of files identified by a pattern specified with the ``--match`` option, delete all but the COUNT most-recently-modified files in that group. This option is *required*. ``--dist-dir=DIR, -d DIR`` Directory where the distributions are. This defaults to the value of the ``bdist`` command's ``--dist-dir`` option, which will usually be the project's ``dist`` subdirectory. **Example 1**: Delete all .tar.gz files from the distribution directory, except for the 3 most recently modified ones:: setup.py rotate --match=.tar.gz --keep=3 **Example 2**: Delete all Python 2.3 or Python 2.4 eggs from the distribution directory, except the most recently modified one for each Python version:: setup.py rotate --match=-py2.3*.egg,-py2.4*.egg --keep=1 .. _saveopts: ``saveopts`` - Save used options to a configuration file ======================================================== Finding and editing ``distutils`` configuration files can be a pain, especially since you also have to translate the configuration options from command-line form to the proper configuration file format. You can avoid these hassles by using the ``saveopts`` command. Just add it to the command line to save the options you used. For example, this command builds the project using the ``mingw32`` C compiler, then saves the --compiler setting as the default for future builds (even those run implicitly by the ``install`` command):: setup.py build --compiler=mingw32 saveopts The ``saveopts`` command saves all options for every command specified on the command line to the project's local ``setup.cfg`` file, unless you use one of the `configuration file options`_ to change where the options are saved. For example, this command does the same as above, but saves the compiler setting to the site-wide (global) distutils configuration:: setup.py build --compiler=mingw32 saveopts -g Note that it doesn't matter where you place the ``saveopts`` command on the command line; it will still save all the options specified for all commands. For example, this is another valid way to spell the last example:: setup.py saveopts -g build --compiler=mingw32 Note, however, that all of the commands specified are always run, regardless of where ``saveopts`` is placed on the command line. Configuration File Options -------------------------- Normally, settings such as options and aliases are saved to the project's local ``setup.cfg`` file. But you can override this and save them to the global or per-user configuration files, or to a manually-specified filename. ``--global-config, -g`` Save settings to the global ``distutils.cfg`` file inside the ``distutils`` package directory. You must have write access to that directory to use this option. You also can't combine this option with ``-u`` or ``-f``. ``--user-config, -u`` Save settings to the current user's ``~/.pydistutils.cfg`` (POSIX) or ``$HOME/pydistutils.cfg`` (Windows) file. You can't combine this option with ``-g`` or ``-f``. ``--filename=FILENAME, -f FILENAME`` Save settings to the specified configuration file to use. You can't combine this option with ``-g`` or ``-u``. Note that if you specify a non-standard filename, the ``distutils`` and ``setuptools`` will not use the file's contents. This option is mainly included for use in testing. These options are used by other ``setuptools`` commands that modify configuration files, such as the `alias`_ and `setopt`_ commands. .. _setopt: ``setopt`` - Set a distutils or setuptools option in a config file ================================================================== This command is mainly for use by scripts, but it can also be used as a quick and dirty way to change a distutils configuration option without having to remember what file the options are in and then open an editor. **Example 1**. Set the default C compiler to ``mingw32`` (using long option names):: setup.py setopt --command=build --option=compiler --set-value=mingw32 **Example 2**. Remove any setting for the distutils default package installation directory (short option names):: setup.py setopt -c install -o install_lib -r Options for the ``setopt`` command: ``--command=COMMAND, -c COMMAND`` Command to set the option for. This option is required. ``--option=OPTION, -o OPTION`` The name of the option to set. This option is required. ``--set-value=VALUE, -s VALUE`` The value to set the option to. Not needed if ``-r`` or ``--remove`` is set. ``--remove, -r`` Remove (unset) the option, instead of setting it. In addition to the above options, you may use any of the `configuration file options`_ (listed under the `saveopts`_ command, above) to determine which distutils configuration file the option will be added to (or removed from). .. _test: ``test`` - Build package and run a unittest suite ================================================= .. warning:: ``test`` is deprecated and will be removed in a future version. Users looking for a generic test entry point independent of test runner are encouraged to use `tox <https://tox.readthedocs.io>`_. When doing test-driven development, or running automated builds that need testing before they are deployed for downloading or use, it's often useful to be able to run a project's unit tests without actually deploying the project anywhere, even using the ``develop`` command. The ``test`` command runs a project's unit tests without actually deploying it, by temporarily putting the project's source on ``sys.path``, after first running ``build_ext -i`` and ``egg_info`` to ensure that any C extensions and project metadata are up-to-date. To use this command, your project's tests must be wrapped in a ``unittest`` test suite by either a function, a ``TestCase`` class or method, or a module or package containing ``TestCase`` classes. If the named suite is a module, and the module has an ``additional_tests()`` function, it is called and the result (which must be a ``unittest.TestSuite``) is added to the tests to be run. If the named suite is a package, any submodules and subpackages are recursively added to the overall test suite. (Note: if your project specifies a ``test_loader``, the rules for processing the chosen ``test_suite`` may differ; see the :ref:`test_loader <test_loader>` documentation for more details.) Note that many test systems including ``doctest`` support wrapping their non-``unittest`` tests in ``TestSuite`` objects. So, if you are using a test package that does not support this, we suggest you encourage its developers to implement test suite support, as this is a convenient and standard way to aggregate a collection of tests to be run under a common test harness. By default, tests will be run in the "verbose" mode of the ``unittest`` package's text test runner, but you can get the "quiet" mode (just dots) if you supply the ``-q`` or ``--quiet`` option, either as a global option to the setup script (e.g. ``setup.py -q test``) or as an option for the ``test`` command itself (e.g. ``setup.py test -q``). There is one other option available: ``--test-suite=NAME, -s NAME`` Specify the test suite (or module, class, or method) to be run (e.g. ``some_module.test_suite``). The default for this option can be set by giving a ``test_suite`` argument to the ``setup()`` function, e.g.:: setup( # ... test_suite="my_package.tests.test_all" ) If you did not set a ``test_suite`` in your ``setup()`` call, and do not provide a ``--test-suite`` option, an error will occur. New in 41.5.0: Deprecated the test command. .. _upload: ``upload`` - Upload source and/or egg distributions to PyPI =========================================================== The ``upload`` command was deprecated in version 40.0 and removed in version 42.0. Use `twine <https://pypi.org/p/twine>`_ instead. For more information on the current best practices in uploading your packages to PyPI, see the Python Packaging User Guide's "Packaging Python Projects" tutorial specifically the section on `uploading the distribution archives <https://packaging.python.org/tutorials/packaging-projects/#uploading-the-distribution-archives>`_.
