===========================
IPython module organization
===========================
As of the 0.11 release of IPython, the top-level packages and modules have
been completely reorganized. This section describes the purpose of the
top-level IPython subpackages.
Subpackage descriptions
=======================
* :mod:`IPython.config`. This package contains the :ref:`configuration system
<config_index>` of IPython, as well as default configuration files for the
different IPython applications.
* :mod:`IPython.core`. This sub-package contains the core of the IPython
interpreter, but none of its extended capabilities.
* :mod:`IPython.deathrow`. This is for code that is outdated, untested,
rotting, or that belongs in a separate third party project. Eventually all
this code will either 1) be revived by someone willing to maintain it with
tests and docs and re-included into IPython or 2) be removed from IPython
proper, but put into a separate third-party Python package. No new code will
be allowed here. If your favorite extension has been moved here please
contact the IPython developer mailing list to help us determine the best
course of action.
* :mod:`IPython.extensions`. This package contains fully supported IPython
extensions. These extensions adhere to the official IPython extension API
and can be enabled by adding them to a field in the configuration file.
If your extension is no longer in this location, please look in
:mod:`IPython.quarantine` and :mod:`IPython.deathrow` and contact the
IPython developer mailing list.
* :mod:`IPython.external`. This package contains third party packages and
modules that IPython ships internally to reduce the number of dependencies.
Usually, these are short, single file modules.
* :mod:`IPython.frontend`. This package contains the various IPython
frontends which communicate with the :mod:`IPython.zmq` kernels (see
:ref:`Messaging in IPython <messaging>`). This includes the
:ref:`ipython notebook <htmlnotebook>`, :ref:`ipython qtconsole
<qtconsole>`, and :ref:`ipython console <two_process_console>` entry points.
* :mod:`IPython.lib`. IPython has many extended capabilities that are not part
of the IPython core. These things will go here and in. Modules in this
package are similar to extensions, but don't adhere to the official
IPython extension API.
* :mod:`IPython.nbformat`. This package contains code related to reading and
writing :ref:`IPython Notebook's <htmlnotebook>` file format (`.ipynb`
files).
* :mod:`IPython.parallel`. This contains :ref:`IPython's parallel computing
system <parallel_index>`. This previously lived under :mod:`IPython.kernel`,
but that module has been deprecated.
* :mod:`IPython.quarantine`. This is for code that doesn't meet IPython's
standards, but that we plan on keeping. To be moved out of this sub-package
a module needs to have approval of the core IPython developers, tests and
documentation. If your favorite extension has been moved here please contact
the IPython developer mailing list to help us determine the best course of
action.
* :mod:`IPython.scripts`. This package contains a variety of top-level
command line scripts. Eventually, these should be moved to the
:file:`scripts` subdirectory of the appropriate IPython subpackage.
* :mod:`IPython.testing`. This package contains code related to the IPython
test suite, which locates and executes the `tests` submodules of all
IPython sub-packages. It also contains decorators and utilities relevant for
testing.
* :mod:`IPython.utils`. This sub-package will contain anything that might
eventually be found in the Python standard library, like things in
:mod:`genutils`. Each sub-module in this sub-package should contain
functions and classes that serve a single purpose and that don't
depend on things in the rest of IPython.
* :mod:`IPython.zmq`. This sub-package contains code related to starting and
managing IPython kernels, which :mod:`IPython.frontend` instances can then
communicate with (see :ref:`Messaging in IPython <messaging>`).
