Creating a new Distutils command
================================
This section outlines the steps to create a new Distutils command.
A new command lives in a module in the :mod:`distutils.command` package. There
is a sample template in that directory called :file:`command_template`. Copy
this file to a new module with the same name as the new command you're
implementing. This module should implement a class with the same name as the
module (and the command). So, for instance, to create the command
``peel_banana`` (so that users can run ``setup.py peel_banana``), you'd copy
:file:`command_template` to :file:`distutils/command/peel_banana.py`, then edit
it so that it's implementing the class :class:`peel_banana`, a subclass of
:class:`distutils.cmd.Command`.
Subclasses of :class:`Command` must define the following methods.
.. method:: Command.initialize_options()
Set default values for all the options that this command supports. Note that
these defaults may be overridden by other commands, by the setup script, by
config files, or by the command-line. Thus, this is not the place to code
dependencies between options; generally, :meth:`initialize_options`
implementations are just a bunch of ``self.foo = None`` assignments.
.. method:: Command.finalize_options()
Set final values for all the options that this command supports. This is
always called as late as possible, ie. after any option assignments from the
command-line or from other commands have been done. Thus, this is the place
to to code option dependencies: if *foo* depends on *bar*, then it is safe to
set *foo* from *bar* as long as *foo* still has the same value it was
assigned in :meth:`initialize_options`.
.. method:: Command.run()
A command's raison d'etre: carry out the action it exists to perform, controlled
by the options initialized in :meth:`initialize_options`, customized by other
commands, the setup script, the command-line, and config files, and finalized in
:meth:`finalize_options`. All terminal output and filesystem interaction should
be done by :meth:`run`.
.. attribute:: Command.sub_commands
*sub_commands* formalizes the notion of a "family" of commands,
e.g. ``install`` as the parent with sub-commands ``install_lib``,
``install_headers``, etc. The parent of a family of commands defines
*sub_commands* as a class attribute; it's a list of 2-tuples ``(command_name,
predicate)``, with *command_name* a string and *predicate* a function, a
string or ``None``. *predicate* is a method of the parent command that
determines whether the corresponding command is applicable in the current
situation. (E.g. we ``install_headers`` is only applicable if we have any C
header files to install.) If *predicate* is ``None``, that command is always
applicable.
*sub_commands* is usually defined at the *end* of a class, because
predicates can be methods of the class, so they must already have been
defined. The canonical example is the :command:`install` command.
