|
|
|
|
Release 0.11
|
|
|
============
|
|
|
|
|
|
IPython 0.11 is a *major* overhaul of IPython, two years in the making. Most
|
|
|
of the code base has been rewritten or at least reorganized, breaking backward
|
|
|
compatibility with several APIs in previous versions. It is the first major
|
|
|
release in two years, and probably the most significant change to IPython since
|
|
|
its inception. We plan to have a relatively quick succession of releases, as
|
|
|
people discover new bugs and regressions. Once we iron out any significant
|
|
|
bugs in this process and settle down the new APIs, this series will become
|
|
|
IPython 1.0. We encourage feedback now on the core APIs, which we hope to
|
|
|
maintain stable during the 1.0 series.
|
|
|
|
|
|
Since the internal APIs have changed so much, projects using IPython as a
|
|
|
library (as opposed to end-users of the application) are the most likely to
|
|
|
encounter regressions or changes that break their existing use patterns. We
|
|
|
will make every effort to provide updated versions of the APIs to facilitate
|
|
|
the transition, and we encourage you to contact us on the `development mailing
|
|
|
list`__ with questions and feedback.

Chris Fonnesbeck recently wrote an `excellent post`__ that highlights some of
|
|
|
our major new features, with examples and screenshots. We encourage you to
|
|
|
read it as it provides an illustrated, high-level overview complementing the
|
|
|
detailed feature breakdown in this document.

|
|
|
|
|
|
A quick summary of the major changes (see below for details):
|
|
|
|
|
|
* **Standalone Qt console**: a new rich console has been added to IPython,
|
|
|
started with `ipython qtconsole`. In this application we have tried to
|
|
|
retain the feel of a terminal for fast and efficient workflows, while adding
|
|
|
many features that a line-oriented terminal simply can not support, such as
|
|
|
inline figures, full multiline editing with syntax highlighting, graphical
|
|
|
tooltips for function calls and much more. This development was sponsored by
|
|
|
`Enthought Inc.`__. See :ref:`below <qtconsole_011>` for details.
|
|
|
|
|
|
.. __: http://enthought.com
|
|
|
|
|
|
* **High-level parallel computing with ZeroMQ**. Using the same architecture
|
|
|
that our Qt console is based on, we have completely rewritten our high-level
|
|
|
parallel computing machinery that in prior versions used the Twisted
|
|
|
networking framework. While this change will require users to update their
|
|
|
codes, the improvements in performance, memory control and internal
|
|
|
consistency across our codebase convinced us it was a price worth paying. We
|
|
|
have tried to explain how to best proceed with this update, and will be happy
|
|
|
to answer questions that may arise. A full tutorial describing these
|
|
|
features `was presented at SciPy'11`__, more details :ref:`below
|
|
|
<parallel_011>`.
|
|
|
|
|
|
.. __: http://minrk.github.com/scipy-tutorial-2011
|
|
|
|
|
|
* **New model for GUI/plotting support in the terminal**. Now instead of the
|
|
|
various `-Xthread` flags we had before, GUI support is provided without the
|
|
|
use of any threads, by directly integrating GUI event loops with Python's
|
|
|
`PyOS_InputHook` API. A new command-line flag `--gui` controls GUI support,
|
|
|
and it can also be enabled after IPython startup via the new `%gui` magic.
|
|
|
This requires some changes if you want to execute GUI-using scripts inside
|
|
|
IPython, see :ref:`the GUI support section <gui_support>` for more details.
|
|
|
|
|
|
* **A two-process architecture.** The Qt console is the first use of a new
|
|
|
model that splits IPython between a kernel process where code is executed and
|
|
|
a client that handles user interaction. We plan on also providing terminal
|
|
|
and web-browser based clients using this infrastructure in future releases.
|
|
|
This model allows multiple clients to interact with an IPython process
|
|
|
through a :ref:`well-documented messaging protocol <messaging>` using the
|
|
|
ZeroMQ networking library.
|
|
|
|
|
|
* **Refactoring.** the entire codebase has been refactored, in order to make it
|
|
|
more modular and easier to contribute to. IPython has traditionally been a
|
|
|
hard project to participate because the old codebase was very monolithic. We
|
|
|
hope this (ongoing) restructuring will make it easier for new developers to
|
|
|
join us.
|
|
|
|
|
|
* **Vim integration**. Vim can be configured to seamlessly control an IPython
|
|
|
kernel, see the files in :file:`docs/examples/vim` for the full details.
|
|
|
This work was done by Paul Ivanov, who prepared a nice `video
|
|
|
demonstration`__ of the features it provides.

|
|
|
|
|
.. __: http://pirsquared.org/blog/2011/07/28/vim-ipython/
|
|
|
|
|
|
* **Integration into Microsoft Visual Studio**. Thanks to the work of the
|
|
|
Microsoft `Python Tools for Visual Studio`__ team, this version of IPython
|
|
|
has been integrated into Microsoft Visual Studio's Python tools open source
|
|
|
plug-in. `Details below`_

.. __: http://pytools.codeplex.com
|
|
|
.. _details below: ms_visual_studio_011_
|
|
|
|
|
|
* **Improved unicode support**. We closed many bugs related to unicode input.
|
|
|
|
|
|
* **Python 3**. IPython now runs on Python 3.x. See :ref:`python3_011` for
|
|
|
details.
|
|
|
|
|
|
* **New profile model**. Profiles are now directories that contain all relevant
|
|
|
information for that session, and thus better isolate IPython use-cases.
|
|
|
|
|
|
* **SQLite storage for history**. All history is now stored in a SQLite
|
|
|
database, providing support for multiple simultaneous sessions that won't
|
|
|
clobber each other as well as the ability to perform queries on all stored
|
|
|
data.
|
|
|
|
|
|
* **New configuration system**. All parts of IPython are now configured via a
|
|
|
mechanism inspired by the Enthought Traits library. Any configurable element
|
|
|
can have its attributes set either via files that now use real Python syntax
|
|
|
or from the command-line.
|
|
|
|
|
|
* **Pasting of code with prompts**. IPython now intelligently strips out input
|
|
|
prompts , be they plain Python ones (``>>>`` and ``...``) or IPython ones
|
|
|
(``In [N]:`` and ``...:``). More details :ref:`here <pasting_with_prompts>`.

|
|
Authors and support
|
|
|
-------------------
|
|
|
|
|
|
Over 60 separate authors have contributed to this release, see :ref:`below
|
|
|
<credits_011>` for a full list. In particular, we want to highlight the
|
|
|
extremely active participation of two new core team members: Evan Patterson
|
|
|
implemented the Qt console, and Thomas Kluyver started with our Python 3 port
|
|
|
and by now has made major contributions to just about every area of IPython.
|
|
|
|
|
|
We are also grateful for the support we have received during this development
|
|
|
cycle from several institutions:
|
|
|
|
|
|
- `Enthought Inc`__ funded the development of our new Qt console, an effort that
|
|
|
required developing major pieces of underlying infrastructure, which now
|
|
|
power not only the Qt console but also our new parallel machinery. We'd like
|
|
|
to thank Eric Jones and Travis Oliphant for their support, as well as Ilan
|
|
|
Schnell for his tireless work integrating and testing IPython in the
|
|
|
`Enthought Python Distribution`_.

|
|
|
us jumpstart the development of this series by restructuring the entire
|

|
codebase two years ago in a way that would make modular development and
|

Development summary: moving to Git and Github
|
|
|
---------------------------------------------
|
|
|
|
|
|
In April 2010, after `one breakage too many with bzr`__, we decided to move our
|
|
|
entire development process to Git and Github.com. This has proven to be one of
|
|
|
the best decisions in the project's history, as the combination of git and
|
|
|
github have made us far, far more productive than we could be with our previous
|
|
|
tools. We first converted our bzr repo to a git one without losing history,
|
|
|
and a few weeks later ported all open Launchpad bugs to github issues with
|
|
|
their comments mostly intact (modulo some formatting changes). This ensured a
|
|
|
smooth transition where no development history or submitted bugs were lost.
|
|
|
Feel free to use our little Launchpad to Github issues `porting script`_ if you
|
|
|
need to make a similar transition.

|
|
|
|
|
|
These simple statistics show how much work has been done on the new release, by
|
|
|
comparing the current code to the last point it had in common with the 0.10
|
|
|
series. A huge diff and ~2200 commits make up this cycle::
|
|
|
|
|
|
git diff $(git merge-base 0.10.2 HEAD) | wc -l
|
|
|
288019
|
|
|
|
|
|
git log $(git merge-base 0.10.2 HEAD)..HEAD --oneline | wc -l
|
|
|
2200
|
|
|
|
|
|
Since our move to github, 511 issues were closed, 226 of which were pull
|
|
|
requests and 285 regular issues (:ref:`a full list with links
|
|
|
<issues_list_011>` is available for those interested in the details). Github's
|
|
|
pull requests are a fantastic mechanism for reviewing code and building a
|
|
|
shared ownership of the project, and we are making enthusiastic use of it.
|
|
|
|
|
|
.. Note::
|
|
|
|
|
|
This undercounts the number of issues closed in this development cycle,
|
|
|
since we only moved to github for issue tracking in May 2010, but we have no
|
|
|
way of collecting statistics on the number of issues closed in the old
|
|
|
Launchpad bug tracker prior to that.

|
|
Qt Console
|
|
|
----------
|
|
|
|
|
|
IPython now ships with a Qt application that feels very much like a terminal,
|
|
|
but is in fact a rich GUI that runs an IPython client but supports inline
|
|
|
figures, saving sessions to PDF and HTML, multiline editing with syntax
|
|
|
highlighting, graphical calltips and much more:
|
|
|
|
|
|
.. figure:: ../_static/qtconsole.png

|
|

:target: ../_static/qtconsole.png
|
|
|
|
|
|
The Qt console for IPython, using inline matplotlib plots.
|
|
|
|
|
|
We hope that many projects will embed this widget, which we've kept
|
|
|
deliberately very lightweight, into their own environments. In the future we
|
|
|
may also offer a slightly more featureful application (with menus and other GUI
|
|
|
elements), but we remain committed to always shipping this easy to embed
|
|
|
widget.
|
|
|
|
|
|
See the :ref:`Qt console section <qtconsole>` of the docs for a detailed
|
|
|
description of the console's features and use.

|
|
|
|
|
|
High-level parallel computing with ZeroMQ
|
|
|
-----------------------------------------
|
|
|
|
|
|
We have completely rewritten the Twisted-based code for high-level parallel
|
|
|
computing to work atop our new ZeroMQ architecture. While we realize this will
|
|
|
break compatibility for a number of users, we hope to make the transition as
|
|
|
easy as possible with our docs, and we are convinced the change is worth it.
|
|
|
ZeroMQ provides us with much tighter control over memory, higher performance,
|
|
|
and its communications are impervious to the Python Global Interpreter Lock
|
|
|
because they take place in a system-level C++ thread. The impact of the GIL in
|
|
|
our previous code was something we could simply not work around, given that
|
|
|
Twisted is itself a Python library. So while Twisted is a very capable
|
|
|
framework, we think ZeroMQ fits our needs much better and we hope you will find
|
|
|
the change to be a significant improvement in the long run.
|
|
|
|
|
|
Our manual contains :ref:`a full description of how to use IPython for parallel
|
|
|
computing <parallel_overview>`, and the `tutorial`__ presented by Min
|
|
|
Ragan-Kelley at the SciPy 2011 conference provides a hands-on complement to the
|
|
|
reference docs.

|
|
|
Refactoring
|
|
|
-----------
|
|
|
|
|
|
As of this release, a signifiant portion of IPython has been refactored. This
|
|
|
refactoring is founded on a number of new abstractions. The main new classes
|
|
|
that implement these abstractions are:
|
|
|
|
|
|
* :class:`IPython.utils.traitlets.HasTraits`.
|
|
|
* :class:`IPython.config.configurable.Configurable`.
|
|
|
* :class:`IPython.config.application.Application`.
|
|
|
* :class:`IPython.config.loader.ConfigLoader`.
|
|
|
* :class:`IPython.config.loader.Config`
|
|
|
|
|
|
We are still in the process of writing developer focused documentation about
|
|
|
these classes, but for now our :ref:`configuration documentation
|
|
|
<config_overview>` contains a high level overview of the concepts that these
|
|
|
classes express.
|
|
|
|
|
|
The biggest user-visible change is likely the move to using the config system
|
|
|
to determine the command-line arguments for IPython applications. The benefit
|
|
|
of this is that *all* configurable values in IPython are exposed on the
|
|
|
command-line, but the syntax for specifying values has changed. The gist is
|
|
|
that assigning values is pure Python assignment. Simple flags exist for
|
|
|
commonly used options, these are always prefixed with '--'.
|
|
|
|
|
|
The IPython command-line help has the details of all the options (via
|
|
|
``ipythyon --help``), but a simple example should clarify things; the ``pylab``
|
|
|
flag can be used to start in pylab mode with the qt4 backend::
|
|
|
|
|
|
ipython --pylab=qt
|
|
|
|
|
|
which is equivalent to using the fully qualified form::
|
|
|
|
|
|
ipython --TerminalIPythonApp.pylab=qt
|
|
|
|
|
|
The long-form options can be listed via ``ipython --help-all``.
|
|
|
|
|
|
|
|
|
ZeroMQ architecture
|
|
|
-------------------
|
|
|
|
|
|
There is a new GUI framework for IPython, based on a client-server model in
|
|
|
which multiple clients can communicate with one IPython kernel, using the
|
|
|
ZeroMQ messaging framework. There is already a Qt console client, which can
|
|
|
be started by calling ``ipython qtconsole``. The protocol is :ref:`documented
|
|
|
<messaging>`.
|
|
|
|
|
|
The parallel computing framework has also been rewritten using ZMQ. The
|
|
|
protocol is described :ref:`here <parallel_messages>`, and the code is in the
|
|
|
new :mod:`IPython.parallel` module.
|
|
|
|
|
|
.. _python3_011:
|
|
|
|
|
|
Python 3 support
|
|
|
----------------
|
|
|
|
|
|
A Python 3 version of IPython has been prepared. For the time being, this is
|
|
|
maintained separately and updated from the main codebase. Its code can be found
|
|
|
`here <https://github.com/ipython/ipython-py3k>`_. The parallel computing
|
|
|
components are not perfect on Python3, but most functionality appears to be
|
|
|
working. As this work is evolving quickly, the best place to find updated
|
|
|
information about it is our `Python 3 wiki page`__.

|
|
Unicode
|
|
|
-------
|
|
|
|
|
|
Entering non-ascii characters in unicode literals (``u"€ø"``) now works
|
|
|
properly on all platforms. However, entering these in byte/string literals
|
|
|
(``"€ø"``) will not work as expected on Windows (or any platform where the
|
|
|
terminal encoding is not UTF-8, as it typically is for Linux & Mac OS X). You
|
|
|
can use escape sequences (``"\xe9\x82"``) to get bytes above 128, or use
|
|
|
unicode literals and encode them. This is a limitation of Python 2 which we
|
|
|
cannot easily work around.

Integration with Microsoft Visual Studio
|
|
|
----------------------------------------
|
|
|
|
|
|
IPython can be used as the interactive shell in the `Python plugin for
|
|
|
Microsoft Visual Studio`__, as seen here:

The Microsoft team developing this currently has a release candidate out using
|
|
|
IPython 0.11. We will continue to collaborate with them to ensure that as they
|
|
|
approach their final release date, the integration with IPython remains smooth.

Additional new features
|
|
|
-----------------------
|
|
|
|
|
|
* Added ``Bytes`` traitlet, removing ``Str``. All 'string' traitlets should
|
|
|
either be ``Unicode`` if a real string, or ``Bytes`` if a C-string. This
|
|
|
removes ambiguity and helps the Python 3 transition.
|
|
|
|
|
|
* New magic ``%loadpy`` loads a python file from disk or web URL into
|
|
|
the current input buffer.
|
|
|
|
|
|
* New magic ``%pastebin`` for sharing code via the 'Lodge it' pastebin.
|
|
|
|
|
|
* New magic ``%precision`` for controlling float and numpy pretty printing.
|
|
|
|
|
|
* IPython applications initiate logging, so any object can gain access to
|
|
|
a the logger of the currently running Application with:
|
|
|
|
|
|
.. sourcecode:: python
|
|
|
|
|
|
from IPython.config.application import Application
|
|
|
logger = Application.instance().log
|
|
|
|
|
|
* You can now get help on an object halfway through typing a command. For
|
|
|
instance, typing ``a = zip?`` shows the details of :func:`zip`. It also
|
|
|
leaves the command at the next prompt so you can carry on with it.
|
|
|
|
|
|
* The input history is now written to an SQLite database. The API for
|
|
|
retrieving items from the history has also been redesigned.
|
|
|
|
|
|
* The :mod:`IPython.extensions.pretty` extension has been moved out of
|
|
|
quarantine and fully updated to the new extension API.
|
|
|
|
|
|
* New magics for loading/unloading/reloading extensions have been added:
|
|
|
``%load_ext``, ``%unload_ext`` and ``%reload_ext``.
|
|
|
|
|
|
* The configuration system and configuration files are brand new. See the
|
|
|
configuration system :ref:`documentation <config_index>` for more details.
|
|
|
|
|
|
* The :class:`~IPython.core.interactiveshell.InteractiveShell` class is now a
|
|
|
:class:`~IPython.config.configurable.Configurable` subclass and has traitlets
|
|
|
that determine the defaults and runtime environment. The ``__init__`` method
|
|
|
has also been refactored so this class can be instantiated and run without
|
|
|
the old :mod:`ipmaker` module.
|
|
|
|
|
|
* The methods of :class:`~IPython.core.interactiveshell.InteractiveShell` have
|
|
|
been organized into sections to make it easier to turn more sections
|
|
|
of functionality into components.
|
|
|
|
|
|
* The embedded shell has been refactored into a truly standalone subclass of
|
|
|
:class:`InteractiveShell` called :class:`InteractiveShellEmbed`. All
|
|
|
embedding logic has been taken out of the base class and put into the
|
|
|
embedded subclass.
|
|
|
|
|
|
* Added methods of :class:`~IPython.core.interactiveshell.InteractiveShell` to
|
|
|
help it cleanup after itself. The :meth:`cleanup` method controls this. We
|
|
|
couldn't do this in :meth:`__del__` because we have cycles in our object
|
|
|
graph that prevent it from being called.
|
|
|
|
|
|
* Created a new module :mod:`IPython.utils.importstring` for resolving
|
|
|
strings like ``foo.bar.Bar`` to the actual class.
|
|
|
|
|
|
* Completely refactored the :mod:`IPython.core.prefilter` module into
|
|
|
:class:`~IPython.config.configurable.Configurable` subclasses. Added a new
|
|
|
layer into the prefilter system, called "transformations" that all new
|
|
|
prefilter logic should use (rather than the older "checker/handler"
|
|
|
approach).
|
|
|
|
|
|
* Aliases are now components (:mod:`IPython.core.alias`).
|
|
|
|
|
|
* New top level :func:`~IPython.frontend.terminal.embed.embed` function that can
|
|
|
be called to embed IPython at any place in user's code. On the first call it
|
|
|
will create an :class:`~IPython.frontend.terminal.embed.InteractiveShellEmbed`
|
|
|
instance and call it. In later calls, it just calls the previously created
|
|
|
:class:`~IPython.frontend.terminal.embed.InteractiveShellEmbed`.
|
|
|
|
|
|
* Created a configuration system (:mod:`IPython.config.configurable`) that is
|
|
|
based on :mod:`IPython.utils.traitlets`. Configurables are arranged into a
|
|
|
runtime containment tree (not inheritance) that i) automatically propagates
|
|
|
configuration information and ii) allows singletons to discover each other in
|
|
|
a loosely coupled manner. In the future all parts of IPython will be
|
|
|
subclasses of :class:`~IPython.config.configurable.Configurable`. All IPython
|
|
|
developers should become familiar with the config system.
|
|
|
|
|
|
* Created a new :class:`~IPython.config.loader.Config` for holding
|
|
|
configuration information. This is a dict like class with a few extras: i)
|
|
|
it supports attribute style access, ii) it has a merge function that merges
|
|
|
two :class:`~IPython.config.loader.Config` instances recursively and iii) it
|
|
|
will automatically create sub-:class:`~IPython.config.loader.Config`
|
|
|
instances for attributes that start with an uppercase character.
|
|
|
|
|
|
* Created new configuration loaders in :mod:`IPython.config.loader`. These
|
|
|
loaders provide a unified loading interface for all configuration
|
|
|
information including command line arguments and configuration files. We
|
|
|
have two default implementations based on :mod:`argparse` and plain python
|
|
|
files. These are used to implement the new configuration system.
|
|
|
|
|
|
* Created a top-level :class:`Application` class in
|
|
|
:mod:`IPython.core.application` that is designed to encapsulate the starting
|
|
|
of any basic Python program. An application loads and merges all the
|
|
|
configuration objects, constructs the main application, configures and
|
|
|
initiates logging, and creates and configures any :class:`Configurable`
|
|
|
instances and then starts the application running. An extended
|
|
|
:class:`BaseIPythonApplication` class adds logic for handling the
|
|
|
IPython directory as well as profiles, and all IPython entry points
|
|
|
extend it.
|
|
|
|
|
|
* The :class:`Type` and :class:`Instance` traitlets now handle classes given
|
|
|
as strings, like ``foo.bar.Bar``. This is needed for forward declarations.
|
|
|
But, this was implemented in a careful way so that string to class
|
|
|
resolution is done at a single point, when the parent
|
|
|
:class:`~IPython.utils.traitlets.HasTraitlets` is instantiated.
|
|
|
|
|
|
* :mod:`IPython.utils.ipstruct` has been refactored to be a subclass of
|
|
|
dict. It also now has full docstrings and doctests.
|
|
|
|
|
|
* Created a Traits like implementation in :mod:`IPython.utils.traitlets`. This
|
|
|
is a pure Python, lightweight version of a library that is similar to
|
|
|
Enthought's Traits project, but has no dependencies on Enthought's code. We
|
|
|
are using this for validation, defaults and notification in our new component
|
|
|
system. Although it is not 100% API compatible with Enthought's Traits, we
|
|
|
plan on moving in this direction so that eventually our implementation could
|
|
|
be replaced by a (yet to exist) pure Python version of Enthought Traits.
|
|
|
|
|
|
* Added a new module :mod:`IPython.lib.inputhook` to manage the integration
|
|
|
with GUI event loops using `PyOS_InputHook`. See the docstrings in this
|
|
|
module or the main IPython docs for details.
|
|
|
|
|
|
* For users, GUI event loop integration is now handled through the new
|
|
|
:command:`%gui` magic command. Type ``%gui?`` at an IPython prompt for
|
|
|
documentation.
|
|
|
|
|
|
* For developers :mod:`IPython.lib.inputhook` provides a simple interface
|
|
|
for managing the event loops in their interactive GUI applications.
|
|
|
Examples can be found in our :file:`docs/examples/lib` directory.
|
|
|
|
|
|
Backwards incompatible changes
|
|
|
------------------------------
|
|
|
|
|
|
* The Twisted-based :mod:`IPython.kernel` has been removed, and completely
|
|
|
rewritten as :mod:`IPython.parallel`, using ZeroMQ.
|
|
|
|
|
|
* Profiles are now directories. Instead of a profile being a single config file,
|
|
|
profiles are now self-contained directories. By default, profiles get their
|
|
|
own IPython history, log files, and everything. To create a new profile, do
|
|
|
``ipython profile create <name>``.
|
|
|
|
|
|
* All IPython applications have been rewritten to use
|
|
|
:class:`~IPython.config.loader.KeyValueConfigLoader`. This means that
|
|
|
command-line options have changed. Now, all configurable values are accessible
|
|
|
from the command-line with the same syntax as in a configuration file.
|
|
|
|
|
|
* The command line options ``-wthread``, ``-qthread`` and
|
|
|
``-gthread`` have been removed. Use ``--gui=wx``, ``--gui=qt``, ``--gui=gtk``
|
|
|
instead.
|
|
|
|
|
|
* The extension loading functions have been renamed to
|
|
|
:func:`load_ipython_extension` and :func:`unload_ipython_extension`.
|
|
|
|
|
|
* :class:`~IPython.core.interactiveshell.InteractiveShell` no longer takes an
|
|
|
``embedded`` argument. Instead just use the
|
|
|
:class:`~IPython.core.interactiveshell.InteractiveShellEmbed` class.
|
|
|
|
|
|
* ``__IPYTHON__`` is no longer injected into ``__builtin__``.
|
|
|
|
|
|
* :meth:`Struct.__init__` no longer takes `None` as its first argument. It
|
|
|
must be a :class:`dict` or :class:`Struct`.
|
|
|
|
|
|
* :meth:`~IPython.core.interactiveshell.InteractiveShell.ipmagic` has been
|
|
|
renamed :meth:`~IPython.core.interactiveshell.InteractiveShell.magic.`
|
|
|
|
|
|
* The functions :func:`ipmagic` and :func:`ipalias` have been removed from
|
|
|
:mod:`__builtins__`.
|
|
|
|
|
|
* The references to the global
|
|
|
:class:`~IPython.core.interactivehell.InteractiveShell` instance (``_ip``, and
|
|
|
``__IP``) have been removed from the user's namespace. They are replaced by a
|
|
|
new function called :func:`get_ipython` that returns the current
|
|
|
:class:`~IPython.core.interactiveshell.InteractiveShell` instance. This
|
|
|
function is injected into the user's namespace and is now the main way of
|
|
|
accessing the running IPython.
|
|
|
|
|
|
* Old style configuration files :file:`ipythonrc` and :file:`ipy_user_conf.py`
|
|
|
are no longer supported. Users should migrate there configuration files to
|
|
|
the new format described :ref:`here <config_overview>` and :ref:`here
|
|
|
<configuring_ipython>`.
|
|
|
|
|
|
* The old IPython extension API that relied on :func:`ipapi` has been
|
|
|
completely removed. The new extension API is described :ref:`here
|
|
|
<configuring_ipython>`.
|
|
|
|
|
|
* Support for ``qt3`` has been dropped. Users who need this should use
|
|
|
previous versions of IPython.
|
|
|
|
|
|
* Removed :mod:`shellglobals` as it was obsolete.
|
|
|
|
|
|
* Removed all the threaded shells in :mod:`IPython.core.shell`. These are no
|
|
|
longer needed because of the new capabilities in
|
|
|
:mod:`IPython.lib.inputhook`.
|
|
|
|
|
|
* New top-level sub-packages have been created: :mod:`IPython.core`,
|
|
|
:mod:`IPython.lib`, :mod:`IPython.utils`, :mod:`IPython.deathrow`,
|
|
|
:mod:`IPython.quarantine`. All existing top-level modules have been
|
|
|
moved to appropriate sub-packages. All internal import statements
|
|
|
have been updated and tests have been added. The build system (setup.py
|
|
|
and friends) have been updated. See :ref:`this section <module_reorg>` of the
|
|
|
documentation for descriptions of these new sub-packages.
|
|
|
|
|
|
* :mod:`IPython.ipapi` has been moved to :mod:`IPython.core.ipapi`.
|
|
|
:mod:`IPython.Shell` and :mod:`IPython.iplib` have been split and removed as
|
|
|
part of the refactor.
|
|
|
|
|
|
* :mod:`Extensions` has been moved to :mod:`extensions` and all existing
|
|
|
extensions have been moved to either :mod:`IPython.quarantine` or
|
|
|
:mod:`IPython.deathrow`. :mod:`IPython.quarantine` contains modules that we
|
|
|
plan on keeping but that need to be updated. :mod:`IPython.deathrow` contains
|
|
|
modules that are either dead or that should be maintained as third party
|
|
|
libraries. More details about this can be found :ref:`here <module_reorg>`.
|
|
|
|
|
|
* Previous IPython GUIs in :mod:`IPython.frontend` and :mod:`IPython.gui` are
|
|
|
likely broken, and have been removed to :mod:`IPython.deathrow` because of the
|
|
|
refactoring in the core. With proper updates, these should still work.
|
|
|
|
|
|
|
|
|
Known Regressions
|
|
|
-----------------
|
|
|
|
|
|
We do our best to improve IPython, but there are some known regressions in 0.11
|
|
|
relative to 0.10.2. First of all, there are features that have yet to be
|
|
|
ported to the new APIs, and in order to ensure that all of the installed code
|
|
|
runs for our users, we have moved them to two separate directories in the
|
|
|
source distribution, `quarantine` and `deathrow`. Finally, we have some other
|
|
|
miscellaneous regressions that we hope to fix as soon as possible. We now
|
|
|
describe all of these in more detail.
|
|
|
|
|
|
Quarantine
|
|
|
~~~~~~~~~~
|
|
|
|
|
|
These are tools and extensions that we consider relatively easy to update to
|
|
|
the new classes and APIs, but that we simply haven't had time for. Any user
|
|
|
who is interested in one of these is encouraged to help us by porting it and
|
|
|
submitting a pull request on our `development site`_.
|
|
|
|
|
|
.. _development site: http://github.com/ipython/ipython
|
|
|
|
|
|
Currently, the quarantine directory contains::
|
|
|
|
|
|
clearcmd.py ipy_fsops.py ipy_signals.py
|
|
|
envpersist.py ipy_gnuglobal.py ipy_synchronize_with.py
|
|
|
ext_rescapture.py ipy_greedycompleter.py ipy_system_conf.py
|
|
|
InterpreterExec.py ipy_jot.py ipy_which.py
|
|
|
ipy_app_completers.py ipy_lookfor.py ipy_winpdb.py
|

|
ipy_autoreload.py ipy_profile_doctest.py ipy_workdir.py
|
|
|
ipy_completers.py ipy_pydb.py jobctrl.py
|
|
|
ipy_editors.py ipy_rehashdir.py ledit.py
|
|
|
ipy_exportdb.py ipy_render.py pspersistence.py
|
|
|
ipy_extutil.py ipy_server.py win32clip.py
|
|
|
|
|
|
Deathrow
|
|
|
~~~~~~~~
|
|
|
|
|
|
These packages may be harder to update or make most sense as third-party
|
|
|
libraries. Some of them are completely obsolete and have been already replaced
|
|
|
by better functionality (we simply haven't had the time to carefully weed them
|
|
|
out so they are kept here for now). Others simply require fixes to code that
|
|
|
the current core team may not be familiar with. If a tool you were used to is
|
|
|
included here, we encourage you to contact the dev list and we can discuss
|
|
|
whether it makes sense to keep it in IPython (if it can be maintained).
|
|
|
|
|
|
Currently, the deathrow directory contains::
|
|
|
|
|
|
astyle.py ipy_defaults.py ipy_vimserver.py
|
|
|
dtutils.py ipy_kitcfg.py numeric_formats.py
|
|
|
Gnuplot2.py ipy_legacy.py numutils.py
|
|
|
GnuplotInteractive.py ipy_p4.py outputtrap.py
|
|
|
GnuplotRuntime.py ipy_profile_none.py PhysicalQInput.py
|
|
|
ibrowse.py ipy_profile_numpy.py PhysicalQInteractive.py
|
|
|
igrid.py ipy_profile_scipy.py quitter.py*
|
|
|
ipipe.py ipy_profile_sh.py scitedirector.py
|
|
|
iplib.py ipy_profile_zope.py Shell.py
|
|
|
ipy_constants.py ipy_traits_completer.py twshell.py
|
|
|
|
|
|
|
|
|
Other regressions
|
|
|
~~~~~~~~~~~~~~~~~
|
|
|
|
|
|
* The machinery that adds functionality to the 'sh' profile for using IPython
|
|
|
as your system shell has not been updated to use the new APIs. As a result,
|
|
|
only the aesthetic (prompt) changes are still implemented. We intend to fix
|
|
|
this by 0.12. Tracked as issue 547_.
|
|
|
|
|
|
.. _547: https://github.com/ipython/ipython/issues/547
|
|
|
|
|
|
* The installation of scripts on Windows was broken without setuptools, so we
|
|
|
now depend on setuptools on Windows. We hope to fix setuptools-less
|
|
|
installation, and then remove the setuptools dependency. Issue 539_.
|
|
|
|
|
|
.. _539: https://github.com/ipython/ipython/issues/539
|
|
|
|
|
|
* The directory history `_dh` is not saved between sessions. Issue 634_.

|
Removed Features
|
|
|
----------------
|
|
|
|
|
|
As part of the updating of IPython, we have removed a few features for the
|
|
|
purposes of cleaning up the codebase and interfaces. These removals are
|
|
|
permanent, but for any item listed below, equivalent functionality is
|
|
|
available.
|
|
|
|
|
|
* The magics Exit and Quit have been dropped as ways to exit IPython. Instead,
|
|
|
the lowercase forms of both work either as a bare name (``exit``) or a
|
|
|
function call (``exit()``). You can assign these to other names using
|
|
|
exec_lines in the config file.
