Command(_Command): + """ + Setuptools internal actions are organized using a *command design pattern*. + This means that each action (or group of closely related actions) executed during + the build should be implemented as a ``Command`` subclass. + + These commands are abstractions and do not necessarily correspond to a command that + can (or should) be executed via a terminal, in a CLI fashion (although historically + they would). + + When creating a new command from scratch, custom defined classes **SHOULD** inherit + from ``setuptools.Command`` and implement a few mandatory methods. + Between these mandatory methods, are listed: + + .. method:: initialize_options(self) + + Set or (reset) all options/attributes/caches used by the command + to their default values. Note that these values may be overwritten during + the build. + + .. method:: finalize_options(self) + + Set final values for all options/attributes used by the command. + Most of the time, each option/attribute/cache should only be set if it does not + have any value yet (e.g. ``if self.attr is None: self.attr = val``). + + .. method:: run(self) + + Execute the actions intended by the command. + (Side effects **SHOULD** only take place when ``run`` is executed, + for example, creating new files or writing to the terminal output). + + A useful analogy for command classes is to think of them as subroutines with local + variables called "options". The options are "declared" in ``initialize_options()`` + and "defined" (given their final values, aka "finalized") in ``finalize_options()``, + both of which must be defined by every command class. The "body" of the subroutine, + (where it does all the work) is the ``run()`` method. + Between ``initialize_options()`` and ``finalize_options()``, ``setuptools`` may set + the values for options/attributes based on user's input (or circumstance), + which means that the implementation should be careful to not overwrite values in + ``finalize_options`` unless necessary. + + Please note that other commands (or other parts of setuptools) may also overwrite + the values of the command's options/attributes multiple times during the build + process. + Therefore it is important to consistently implement ``initialize_options()`` and + ``finalize_options()``. For example, all derived attributes (or attributes that + depend on the value of other attributes) **SHOULD** be recomputed in + ``finalize_options``. + + When overwriting existing commands, custom defined classes **MUST** abide by the + same APIs implemented by the original class.
