The Emacs IPython Notebook
=====================================
.. image:: ein_logo.jpg
.. el:package:: ein
The `Emacs IPython Notebook (EIN)`_ package provides a `Jupyter Notebook`_
client and integrated REPL (like SLIME_) in Emacs. EIN improves notebook editing
by allowing you to use Emacs. It also expose IPython features such as code
evaluation, object inspection and code completion. These features can be
accessed anywhere in Emacs and improve Python code editing and reading in
general in Emacs.
.. _`Emacs IPython Notebook (EIN)`: https://github.com/millejoh/emacs-ipython-notebook
.. _SLIME: http://common-lisp.net/project/slime/
.. _`Jupyter Notebook`: https://jupyter-notebook.readthedocs.io/en/stable/
Highlighted features:
* Copy/paste cells in and between notebooks.
* Console integration: You can easily connect to a kernel via a console
application. This enables you to start debugging in the same kernel. It is
even possible to connect a console over ssh [#]_.
* An IPython kernel can be "connected" to a buffer. This enables you to evaluate
buffer/region using same kernel as notebook. Notebook goodies such as tooltip
help, help browser and code completion are available in these buffers. [#]_
* Jump to definition (go to the definition by executing ``M-.`` over an
object).
* Execute code from an org-mode source block in a running kernel.
Other notebook features:
* Inline images
* Auto/manual-completion
* Popup (tooltip) help
* Syntax highlighting in each cell type (Python/Markdown/ReST/HTML)
* Help browser (opens when executing ``function?``)
* Traceback viewer
* Integration with the emacs debugger

Quick try
---------
The fastest way to get EIN running in this modern age is to download from MELPA_
or, if you are a spacemacs_ user, through installing the ipython-notebook_
layer. Using zeroein_ is no longer supported, though in theory it should still
work.
If you are installing from MELPA_ and have issues with some functions not being
available after emacs starts, try adding the following to your emacs init file:
.. sourcecode:: cl
(package-initialize)
(require 'ein)
(require 'ein-notebook)
(require 'ein-subpackages)
.. _spacemacs: http://spacemacs.org/
.. _ipython-notebook: http://spacemacs.org/layers/+lang/ipython-notebook/README.html
.. _zeroein: http://tkf.github.io/emacs-ipython-notebook/#quick-try
.. _requirements-label:
Requirements
------------
* EMACS 25.3, 26.x, or 27
* `Jupyter Notebook`_ 4.x or higher
* IPython_ 5.8 or higher.
* Tornado_ 4.0.2 or higher.
* `websocket.el`_ >= 1.7
* `request.el`_ >= 0.3
* `request-deferred.el`_ >= 0.2
* `dash`_ >= 2.13
* `s`_ >= 1.11
* `skewer-mode`_ >= 1.6.2:
Skewer mode gives EIN the ability to execute dynamic javascript in the
note book.
* (optional) Jupyterhub_ 0.8 or higher:
EIN supports logging in to Jupyterhub servers using PAM authentication,
though this only works with v0.8, which currently is the development version
of Jupyterhub.
* (optional) markdown-mode
* (optional) python-mode:
It should work with either python.el or python-mode.el. `python.el`_ is
required to use the ``ein:console-open`` command.
* (optional) `smartrep.el`_:
This package enables you to omit typing prefix keys (e.g.,
``C-c C-n C-n C-n ...`` instead of ``C-c C-n C-c C-n C-c C-n ...``).
You need to configure subpackage ``ein-smartrep`` to enable
this feature.
* (optional) `jedi.el`_:
Python auto-completion for emacs using `jedi`_. In your
emacs initialization file add
``(setq ein:completion-backend 'ein:use-ac-jedi-backend)``
Also, EIN heavily relies on standard Emacs libraries including EWOC,
EIEIO and json.el.

Install
-------
.. warning:: As EIN relies on many packages and it will not work
properly with outdated versions, installing it using el-get or
MELPA is highly recommended.
Using el-get
^^^^^^^^^^^^
If you use developmental version of `el-get`_ installation is simple. Emacs
IPython Notebook is registered as package ``ein``. See the `el-get`_ website
for more information.
.. _el-get: https://github.com/dimitri/el-get
.. note:: If you get error "Cannot open load file: request" that means you have
an older version of el-get. You can fix this problem by either (1)
installing request.el manually, (2) using the latest recipe, or (3) updating
el-get to its master.
You can get the latest recipe here:
- https://github.com/dimitri/el-get/blob/master/recipes/ein.rcp
- https://github.com/dimitri/el-get/blob/master/recipes/request.rcp
See `issue 98 <https://github.com/tkf/emacs-ipython-notebook/issues/98>`_
for more information.
Using package.el (MELPA)
^^^^^^^^^^^^^^^^^^^^^^^^
You can install EIN using `package.el`_ when the MELPA_ package repository
is added to its setting. See MELPA_ website for more information.
.. _`package.el`: http://emacswiki.org/emacs/ELPA
.. _MELPA: https://github.com/milkypostman/melpa
Manual install
^^^^^^^^^^^^^^
Put Emacs lisp ``ein*.el`` files and the Python file ``ein_remote_safe.py`` in
a directory defined in your :el:symbol:`load-path`.
You should byte compile EIN, especially when using MuMaMo, otherwise
editing large notebook will be very slow. You can use the following
command to compile EIN. If you don't specify all the optional
packages, there will be compiler warning but that is OK as long as you
don't use that optional package.
.. sourcecode:: sh
emacs -Q -batch -L . \ # don't forget the dot!
-L PATH/TO/websocket/ \
-L PATH/TO/requests/ \
-L PATH/TO/nxhtml/util/ \ # optional (for MuMaMo)
-L PATH/TO/auto-complete/ \ # optional
-L PATH/TO/popup/ \ # optional (for auto-complete)
-L PATH/TO/fuzzy/ \ # optional (for auto-complete)
-L PATH/TO/smartrep/ \ # optional
-L PATH/TO/rst-mode/ \ # optional
-f batch-byte-compile *.el
Setup
^^^^^
Here is the minimal configuration. See customization_ for more details.
.. sourcecode:: cl
(require 'ein)
(require 'ein-notebook)
(require 'ein-subpackages)
Usage
-----
1. Start the `Jupyter notebook server`_ from the terminal or call ``M-x
ein:run`` or ``M-x ein:jupyter-server-start`` from emacs. Note starting the
notebook server from emacs will automatically call
``ein:jupyter-server-login-and-open``, making steps 2 and 3 below
unnecessary!
2. If you have token or password authentication enabled then you will need to
call ``M-x ein:login`` and enter the appropriate password.
Assuming authentication works the :ref:`notebooklist
<notebook-list-commands>` buffer will automatically open.
3. In the notebook list buffer, you can open notebooks by selecting the
``[Open]`` buttons. See the :ref:`notebook <notebook-commands>` section for
operations and commands available in the notebook buffer.
.. _`Jupyter notebook server`:
https://jupyter.readthedocs.io/en/latest/running.html
Commands/Keybinds
-----------------
.. _notebook-list-commands:
Running a Jupyter Notebook Server from Emacs
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Using the commands below you start a jupyter notebook session from within emacs
(i.e. no need to drop to the terminal shell and call ``jupyter notebook``). EIN
will also try to determine the access url and token authentication for the
running server and automatically log you in.
Note that the below work best with current (> v4.3.1) versions of jupyter.
.. el:function:: ein:jupyter-server-start
.. el:function:: ein:run
.. el:function:: ein:jupyter-server-stop
.. el:function:: ein:jupyter-server-login-and-open
.. el:variable:: ein:jupyter-server-command
.. el:variable:: ein:jupyter-server-use-subcommand
.. el:variable:: ein:jupyter-default-notebook-directory
.. el:variable:: ein:jupyter-server-args
Notebook list
^^^^^^^^^^^^^
You can start notebook by ``M-x ein:notebooklist-open`` and enter the
port or URL of the IPython notebook server.
.. el:function:: ein:notebooklist-open
.. el:function:: ein:notebooklist-new-notebook
.. el:function:: ein:notebooklist-open-notebook-global
.. el:function:: ein:notebooklist-login
.. el:function:: ein:junk-new
.. el:function:: ein:notebooklist-enable-keepalive
.. el:function:: ein:notebooklist-disable-keepalive
.. el:keymap:: ein:notebooklist-mode-map
:exclude: widget-button
.. _notebook-commands:
Notebook
^^^^^^^^
The following keybindings are available in notebook buffers. Modified notebooks
are saved automatically with a frequency dependenant on the setting of
`ein:notebook-autosave-frequency`. If `ein:notebook-create-checkpoint-on-save`
is True than a checkpoint will also be generated in the Jupyter server every
time the notebook is saved. A notebook can be returned to a previous checkpoint
via `ein:notebook-restore-to-checkpoint`. Checkpoints can also be manually
created via `ein:notebook-create-checkpoint`.
.. el:keymap:: ein:notebook-mode-map
:replace: s/C-c TAB/C-c C-i/
s/C-c RET/C-c C-m/
.. el:function:: ein:worksheet-execute-all-cells
.. el:function:: ein:worksheet-execute-all-cells-above
.. el:function:: ein:worksheet-execute-all-cells-below
.. el:function:: ein:worksheet-delete-cell
.. el:function:: ein:junk-rename
.. el:function:: ein:iexec-mode
.. el:function:: ein:notebook-create-checkpoint
.. el:function:: ein:notebook-restore-to-checkpoint
.. el:function:: ein:notebook-enable-autosaves
.. el:function:: ein:notebook-disable-autosaves
Polymode in the Notebook
^^^^^^^^^^^^^^^^^^^^^^^^
EIN now provides proper multi-major mode support in notebook buffers using
polymode_. To use simply set :el:symbol:`ein:polymode` to ``t`` and restart
emacs.
.. el:variable:: ein:polymode
.. _polymode: https://polymode.github.io
Advanced Editing
^^^^^^^^^^^^^^^^
Worksheet cells can be edited in a manner similar to `source blocks`_ in Org
buffers. Use ``C-c '`` to edit the contents of the current cell. You can execute
the contents of the buffer and the results will be sent to the output of the
cell being edited.
.. el:keymap:: ein:edit-cell-mode-map
.. el:function:: ein:edit-cell-contents
.. el:function:: ein:edit-cell-exit
.. el:function:: ein:edit-cell-abort
.. el:function:: ein:edit-cell-save
.. el:function:: ein:edit-cell-save-and-execute
.. _`source blocks`: http://orgmode.org/manual/Editing-source-code.html#Editing-source-code
Connected buffer
^^^^^^^^^^^^^^^^
You can connect any buffer (though typically a buffer that contains a Python
file) to an opened notebook and use the kernel of that notebook to execute code,
inspect objects, auto-complete code, jump to the other source, etc. Once the
buffer is connected to the notebook, minor mode :el:symbol:`ein:connect-mode` is
enabled and the following keybinds are available.
.. el:keymap:: ein:connect-mode-map
:replace: s/C-c TAB/C-c C-i/
Other useful commands:
.. el:function:: ein:connect-to-notebook-command
.. el:function:: ein:connect-eval-buffer
.. el:function:: ein:connect-run-buffer
Shared output buffer
^^^^^^^^^^^^^^^^^^^^
.. el:function:: ein:shared-output-pop-to-buffer
.. el:keymap:: ein:shared-output-mode-map
Traceback viewer
^^^^^^^^^^^^^^^^
Tracebacks from the notebook buffer can be difficult to understand. You can
open a Traceback viewer by calling :el:symbol:`ein:notebook-view-traceback`.
In the Traceback viewer, following keybinds are available.
.. el:keymap:: ein:traceback-mode-map
PyTools
^^^^^^^
These commands can be used in the notebook buffer and the connected
buffer.
.. el:function:: ein:pytools-doctest
.. el:function:: ein:pytools-whos
.. el:function:: ein:pytools-hierarchy
.. el:function:: ein:pytools-pandas-to-ses
.. el:function:: ein:pytools-export-buffer
Misc
^^^^

Org-mode Integration (ob-ein)
-----------------------------
Configuration:
::
M-x customize-group RET org-babel
Org Babel Load Languages:
Insert (ein . t)
For example, '((emacs-lisp . t) (ein . t))
Snippet:
.. code:: python
#BEGIN_SRC *language* :session localhost :results raw drawer
import numpy, math, matplotlib.pyplot as plt
%matplotlib inline
x = numpy.linspace(0, 2*math.pi)
plt.plot(x, numpy.sin(x))
#+END_SRC
*Language* can be ``ein-python``, ``ein-r``, or ``ein-julia``. **The relevant** `jupyter kernel`_ **must be installed before use**. Additional languages can be
configured via::
M-x customize-group RET ein
Ob Ein Languages
The format for the `:session` header argument is
`{url-or-port}/{path-to-notebook}`. Just specifying `{url-or-port}` executes
your source block in a single anonymous notebook (this effects an ipython repl
in org). You should also specify `:results raw drawer` for proper rendering
inside the org buffer. For example:
.. code:: python
#+BEGIN_SRC ein-python :session localhost :results raw drawer
import sys
a = 14500
b = a+1000
sys.version
#+END_SRC
If your code block generates an image, like from an matplotlib plot, ein will
automatically save to a file in the directory specified by
:el:symbol:`ein:org-inline-image-directory` and generate an appropriate inline
link. You can also specify the file to save the image to using by the `:image`
argument as in the example below:
.. code:: python
#BEGIN_SRC ein :session localhost :results raw drawer :image output.png
import matplotlib.pyplot as plt
import numpy as np
%matplotlib inline
x = np.linspace(0, 1, 100)
y = np.random.rand(100,1)
plt.plot(x,y)
#+END_SRC
To get proper syntax highlighting for non-Python kernels, use the function
:el:symbol:`ein:org-register-lang-mode` to define a new ein-based org source
language. For example, to get proper syntax highlighting for an R kernel, first call
.. sourcecode:: cl
(ein:org-register-lang-mode "ein-R" 'R)
Then org SRC blocks with language "ein-R" will use R syntax highlighting:
.. code:: R
#BEGIN_SRC ein-R :session localhost :results raw drawer :image output.png
plot(1:10, 1:10)
#+END_SRC
You can also link to an IPython notebook from org-mode_ files.
1. Call org-mode function :el:symbol:`org-store-link`
[#org-store-link]_ in notebook buffer. You can select a region to
specify a position in the notebook.
2. Go to org-mode file and type ``C-c C-l``
(:el:symbol:`org-insert-link`). This will insert a link to the
notebook.
3. Type ``C-c C-o`` (:el:symbol:`org-open-at-point`) to open
the link at the point of cursor.

Customization
^^^^^^^^^^^^^

Support for The Hy Language (EXPERIMENTAL)
------------------------------------------
New in v0.14, ein has limited support for executing hy_ code in a notebook
running an ipython kernel. Before trying this feature you will need to install hy
per the quickstart_ instructions.
Once you have set up hy_ in your ipython kernel, open or create a notebook
running this kernel and create or go to an empty cell. You will need to change
the cell type to hy using :el:symbol:`ein:worksheet-change-cell-type`. Once that
is done you can enter hy expressions and they will be correctly evaluated by the
kernel!
If you are running a `hy kernel`_ you can, of course, write hy expressions in
code cells and have the expected results.

Gotchas and caveats
-------------------
Although EIN mostly works fine, there are some deficits I noticed but
have not fixed yet. It seems that they originate from some upstream
bugs so there is little I can do in EIN (but I'm not sure -- it's
possible that I am misusing the libraries!).
If you know how to fix/workaround them, patches are very welcome.
:el:symbol:`url-retrieve`
^^^^^^^^^^^^^^^^^^^^^^^^^
While using EIN, probably most of the error messages are about server
connections. It looks like the problem is in :el:symbol:`url-retrieve`.
But in those cases you don't lose any notebook data and your IPython
kernel is fine. You can just type the command again and it will go
fine most of the time. For saving notebook, I implemented code to
retry when there is an error comes from :el:symbol:`url-retrieve` to
make it even safer.
MuMaMo
^^^^^^
When using MuMaMo based notebook mode, you will notice that
highlighting outside of the cell input is turned off while you are in
the input area. It seems there is a bug in MuMaMo [#m3bug]_.
If you are using smartrep and MuMaMo together, see also the warning in
:el:symbol:`ein:use-smartrep` document.
.. [#m3bug] See the relevant bug report I posted:
https://bugs.launchpad.net/nxhtml/+bug/1013794
.. _gotchas-python-mode.el:
python-mode.el
^^^^^^^^^^^^^^
Using `python-mode.el`_ without fisrt byte-compiling can cause a segfault with
the MuMaMo based notebook mode.
Also, ``mumamo-idle-set-major-mode`` generates the error message
``(wrong-type-argument listp python-saved-check-command)`` time to time, making
minibuffer bit noisy while editing notebook. See Tips_ to fix this problem.
Advanced
--------
By telling IPython a little bit about Emacs Lisp, you can execute
Emacs Lisp from IPython, just like you can execute Javascript in the
web client. See `emacslisp.py`_ for more details.
.. sourcecode:: python
In [1]:
%run PATH/TO/emacslisp.py
In [2]:
EmacsLisp('(+ 1 2 3)')
Out [2]:
6
.. _`emacslisp.py`:
https://github.com/millejoh/emacs-ipython-notebook/blob/master/tools/emacslisp.py
Reporting issues
----------------
Please use ``M-x ein:dev-bug-report-template`` to write a bug report.
It pops up a buffer containing some system information and instruction
for bug report.
Logging
^^^^^^^
Sometime more information than provided in the ``*Message*`` buffer is needed to
debug.
1. Execute ``(ein:log-set-level 'debug)``
(e.g., ``M-: (ein:log-set-level 'debug) RET``).
2. Then do some operation which cause the problem.
3. Go to the log buffer ``_*ein:log-all*`` (it starts with a space)
and paste the whole buffer to the issue tracker.
Please enclose the log with three backquotes to make the snippet as
a code block, like this::
```
[verbose] Start logging. @#<buffer *ein: 8888/NAME*>
[info] Notebook NAME is ready @#<buffer *ein: 8888/NAME*>
[info] Kernel started: 5e4f74d1-ce91-4e7e-9575-9646adea5172 @#<buffer *scratch*>
```
See also: `GitHub Flavored Markdown - Introduction
<http://github.github.com/github-flavored-markdown/>`_
If it is too long, you can use paste bin service such as
`gist <https://gist.github.com/>`_.
websocket.el
""""""""""""
websocket.el has its own logging buffer. Sometime it is useful to see this
log. To do this:
1. ``(require 'ein-dev)``
2. ``(setq websocket-debug t)`` or call :el:symbol:`ein:dev-start-debug`.
3. Then do the operation which causes the problem.
4. Go to log buffer using
:el:symbol:`ein:dev-pop-to-debug-shell` and
:el:symbol:`ein:dev-pop-to-debug-iopub`.
These command must be called in the notebook buffer.
Debugging
^^^^^^^^^
If you are interested in debugging EIN, you should start by calling the command
:el:symbol:`ein:dev-start-debug`. If the bug is websocket related, you may need
to run it with a prefix key like this: ``C-u M-x ein:dev-start-debug RET`` to
get a backtrace. This command sets :el:symbol:`debug-on-error` to ``t`` and
does some patching to the debugger. This patching is required because printing
EWOC objects freezes Emacs otherwise. It also changes log level to report
everything the log buffer. You can reset the patch and log level with
:el:symbol:`ein:dev-stop-debug`.

v0.9.1
------
* Fix issues with shared-output and notebook connected buffers.
v0.9.0
------
* Add support for setting slide attributes for notebook/worksheet cells.
v0.8.2

.. _`#92`: https://github.com/millejoh/emacs-ipython-notebook/issues/92
.. _`#91`: https://github.com/millejoh/emacs-ipython-notebook/issues/91
v0.8.1
------
* Fix potential overwrite issue caused by setting buffer-file-name.
v0.8.0
------
* Support for multiple Jupyter kernels. EIN still thinks everything is
Python code, but it should be possible to create notebooks that run
any language supported by a Jupyter kernel.
v0.7.1
------
* Fix bug saving images in v4 notebook format.
* Be more graceful handling errors during content saves.
v0.7
----
* Support logging in to password protected jupyter servers.
v0.6
----
* Deprecate ein:set-buffer-file-name, instead use the power of Python!
* Jump to notebook cells from traceback buffers.
* Run ipbd/pdb from a comint buffer.
* Fix serious bug with starting and restarting kernels in IPython 3.x.
v0.5
----
* Add support for stdin channel. This mean getpass.getpass() and the ipdb work in notebook buffers.
v0.4
----
* Finalizing support for IPython 3.0.
* Better support for globally opening notebooks stored in a directory hierarchy.
* Partial refactoring of the interace to IPython's content/notebook REST interface into
ein-contents-api.el.
* ein-mumamo.el has been moved into its own package, ein-mumamo. This should get rid
of compilation errors for anyone who does not happen to have nxhtml installed.
* Restore support for heading level cells with nbformat v4 notebooks.
* New (buggy) pytools function :el:symbol:`ein:pytools-export-buffer` for using nbconvert on a notebook
buffer.
v0.3
----
* New maintainer - John Miller (millejoh at mac dot com)
* Official repository is now at https://github.com/millejoh/emacs-ipython-notebook
* Support for IPython 2.x and 3.x added.
* Support for IPython 1.x and earlier removed.
v0.2.1
------
* Cached auto-complete is removed.
:el:symbol:`ac-source-ein-cached` and :el:symbol:`ac-complete-ein-cached`
are obsolete.
:el:symbol:`ein:ac-max-cache` has no effect now.
* :el:symbol:`ein:query-timeout` is `nil` if `curl` backend is used
by request.el_.
* History search interface (:el:symbol:`helm-ein-kernel-history` and
:el:symbol:`anything-ein-kernel-history`) discards duplications.
This functionality requires at least version 4.0 of IPython kernel.
It is introduced by the pull request
`ipython/ipython#2792 <https://github.com/ipython/ipython/pull/2792>`_.
As of writing, you need IPython 0.14.dev from github.
For older versions of kernels, it continues to work but you will
see duplications.
* Add support for `kernel_info` request for IPython kernel protocol,
which is introduced by
`ipython/ipython#2649 <https://github.com/ipython/ipython/issues/2649>`_.
This protocol is not used in EIN anywhere yet.
* Use request.el_ for smoother experience.
v0.2
----
* Preliminary login support. See :el:symbol:`ein:notebooklist-login`.
* Code completion in notebook happens *really* automatically.
You don't need to hit a key to start completion.
* :el:symbol:`ein:console-open` works without `python.el`_.
* Expand code cell output on execution.
(`#88 <https://github.com/tkf/emacs-ipython-notebook/issues/88>`_).
* Improve :el:symbol:`ein:completer-dot-complete` and
:el:symbol:`ein:jedi-dot-complete`. Do not expand common part when
inserting dot, to make typing code containing dots less surprising.
* Add support for Jedi.el_. See :el:symbol:`ein:jedi-setup`.
* Add a simple org-mode link support.
* Add built-in multiple language fontification for notebook:
:el:symbol:`ein:notebook-multilang-mode`.
This is the new default for :el:symbol:`ein:notebook-modes`.
* Add helm/anything interface to search kernel history:
:el:symbol:`helm-ein-kernel-history` and
:el:symbol:`anything-ein-kernel-history`.
See also the configurable options to use these commands:
:el:symbol:`ein:helm-kernel-history-search-key` and
:el:symbol:`ein:anything-kernel-history-search-key`.
* Preliminary support for multiple worksheets.
* Rename notion of "scratch notebook" to "junk notebook".
This is to avoid confusion with newly added "scratch sheet".
Old commands are renamed to :el:symbol:`ein:junk-new` and
:el:symbol:`ein:junk-rename`.
* Preferred MIME types to be used can be configured using the variable
:el:symbol:`ein:output-type-preference`.
* HTML content is rendered SHR (Simple HTML Renderer) by default.
Use :el:symbol:`ein:shr-env` to tweak how HTML rendered.
* :el:symbol:`ein:notebook-discard-output-on-save` is obsolete now.
* Support execution history. Commands
:el:symbol:`ein:worksheet-previous-input-history` and
:el:symbol:`ein:worksheet-next-input-history` can be used
to insert previously executed code into the current cell.
* Add :el:symbol:`ein:pseudo-console-mode`.
* Add "scratch sheet". This acts almost as same as worksheet, but you
don't need to save it. You can use try any code without saving
junks in your notebook. Use the command
:el:symbol:`ein:notebook-scratchsheet-open` to open scratch sheet.
* Menu support in notebook mode and notebook list mode.
* Auto-connection support.
The new function :el:symbol:`ein:connect-to-default-notebook` can be
added to :el:symbol:`python-mode-hook` to automatically connect
python-mode buffers to default notebook specified by
:el:symbol:`ein:connect-default-notebook`. See also
:el:symbol:`ein:notebooklist-load`.
* Add :el:symbol:`ein:worksheet-execute-cell-and-insert-below`.
* Change the timing to trigger auto-execution in connected buffer.
It was triggered on save before. Now it is on run, eval or reload.
See :el:symbol:`ein:connect-toggle-autoexec`.
v0.1.2
------
* Mostly refactoring for worksheet support in v0.2.
* Rename command :el:symbol:`ein:notebook-console-open` to
:el:symbol:`ein:console-open`. It is available from non-notebook
buffer such as connected buffer now.
* Add :el:symbol:`ein:connect-reload-buffer`.
Old default :el:symbol:`ein:connect-run-buffer` behavior is
replaced by this function. :el:symbol:`ein:connect-run-buffer`
now actually runs buffer instead of loading it.
v0.1.1
------
* Support `auto-complete.el`_\ 's popup/quick help.
* Add :el:symbol:`ein:notebooklist-first-open-hook`.
* Handle carriage return
(`#13 <https://github.com/tkf/emacs-ipython-notebook/issues/13>`_).
* :el:symbol:`ein:connect-to-notebook-command` is improved;
it can connect to the notebook which is not opened yet.
* Plain text type output is favored over LaTeX type output
(previous setting was opposite).
* Workaround indentation problem when using MuMaMo
(`#20 <https://github.com/tkf/emacs-ipython-notebook/issues/20>`_).
See :el:symbol:`ein:use-mumamo-indent-line-function-workaround`.
* Add :el:symbol:`ein:notebook-rename-to-scratch-command`.
* Add :el:symbol:`ein:pytools-pandas-to-ses`.
* Add Imenu support.
* Better heading cell faces.
* Add :el:symbol:`ein:iexec-mode`
* Add auto-execution mode
(see :el:symbol:`ein:connect-toggle-autoexec` and
:el:symbol:`ein:notebook-turn-on-autoexec`).
* Start completion when "." is inserted.
Use :el:symbol:`ein:complete-on-dot` to disable this feature.
* Support tramp. See :el:symbol:`ein:filename-translations`.
* Change callback API in :el:symbol:`ein:kernel-execute`
to adapt messaging protocol change in
`IPython (#2051) <https://github.com/ipython/ipython/pull/2051>`_.
* Add helm/anything support.
Use :el:symbol:`helm-ein-notebook-buffers` or
:el:symbol:`anything-ein-notebook-buffers`.
v0.1
----
* First release.
