"""
|
||||
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. They also **SHOULD** inherit from the
|
||||
original class.
