Add %%octave, %octave, %octave_pull and %octave_push magics to facilitate interaction with Octave via oct2py. This is similar in spirit to the R magic extension.
New `%%capture` cell magic captures stdout/err while running a cell.
Uses `capture_output()` context manager, moved to utils.io from IPython.parallel testing utilities, where it originated.
The caputre objects can be printed as a string, case in which they display the captured stdout, which is also available as `.stdout`. The captured stderr, if any, is in a `.stderr` attribute. A `.show()` method can be called to quickly print both, with stderr being correctly printed to the sys.stderr stream (so the notebook displays it with red highlighting).

Fix 1px margin bouncing of selected menu item.
This fixes the margin of the active menu item to zero, so now the text doesn't shift around, even if you use larger fonts.
To reproduce the original error, zoom your notebook (ctrl-mousewheel, or ctrl-+ in most browsers) and try the menu.
Fix vertical offset due to bold/italics, and bad browser fonts.
Adds a dialog warning users when a problematic monospaced font is detected, so they can change their configuration.
There was a bug in NotebookManager.save_notebook_object.
Here is how to reproduce:
0. Make sure you don't have Untitled0.
1. Open new notebook Untitled0.
2. Rename it to something else.
3. Copy Untitled0.ipynb to the notebook dir from somewhere.
(Do not use notebook UI.)
4. New copied Untitled0 cannot be opened.
The renamed notebook is opened when tried.
Indeed, accessing to http://localhost:XXXX/notebooks shows
duplicated notebook_id.
The problem was that NotebookManager.rev_mapping keeps old notebook
name after renaming.
Make : invalid in filenames in the Notebook JS code.
This only prevents : in the filenames on the JavaScript side of things. Handling this on the server side will be a separate issue that is related to other open issue. I will update those to reflect this.

Rmagic extension to use R (the statistical package) seamlessly from IPython.
The rmagic extension allows R inline code as well as cell level magics. An example notebook is provided in docs/examples/notebooks/rmagic_extension.ipynb to demonstrate its usage.
Main points:
1) Allows capture of plots to R via inline png plots (like --pylab inline)
2) Allows capture of R's stdout() connection to the notebook
3) Allows simple push/pull for array data to/from R (via rpy2) with copy only on push to R -- this seems necessary.
When kernel is died and restarted, or restarted while it is in the
busy state, message "(Busy)" on the window title is not updated. This
problem is fixed by updating document title when restarting.
it seem that show and hide methods fron tooltip where collinding with
jquery, sometime blocking the notebook.
Move from css fadeIn/Out to jQuery fade In/Out, and replace
addRemoveClass by fadeIn/fadeOut
For security reasons, the kernel should not be started until
after the notebook content is completely loaded and on the page.
This prevents people from creating notebooks that run nasty code
on the users machine at load time.
In order to implement this, we had to create a CodeCell.set_kernel
method that allows the kernel attribute of a CodeCell to be set
at a later time. This also fixes some error messages we were
seeing related to the kernel's channels not being setup properly
when a send was attempted.
Use notification to quicky remind use of the tooltip
Use javascript in notebook to make a live demo in
01_notebook_introduction
tooltip docstring is remplaceid for the first use by a live tutorial
I had removed the choice for the user to not restart a dead kernel
but we are using that elsewhere. Eventually we may not give them
a choice, but for now we will use that model.
* Kernel doesn't depend on Notebook or CodeCell.
* CodeCell doesn't depend on Notebook, only Kernel.
* All of the kernel management logic has been moved out of the
Notebook into the Kernel.
* Public methods of the Kernel (execute, complete, etc) take
a callbacks object that registers the callbacks for that msg.

consecutives tab pressing with tooltip does :
- fisrt : show it
- second : expand it
- third : make it sticky for 10s (typing wont dismiss it)
- forth : send the content into the Pager
Completion source based on context is smarter and use codemirror token
mecanisme to propose completions, instead of just plitting text at
whitespace and before dots.
more feature like
-completion based on 2 sources :
* introspection in kernel
* context of current cell (complete with matching words)
* each source has its color in the completer
Warn on nonexistent exclusions in iptest. This will help us avoid common and often baffling errors from simple typos, as well as keeping the exclusions list updated as the code evolves.
Dashboard improvement
see #1658#1676
Allow to shutdown the kernels from the dashboard,
autorefresh dashboard,
add a native upload method, especially for https/chrome/linux that prevent drag and drop
Cython related magic functions: offers the new cell magics %%cython_inline, %%cython_pyximport and %%cython to make it very easy to put cython-accelerated code in a cell and have it loaded interactively.
ENH: Open a notebook from the command line
open notebook files from the command line, just
like ipython can open (run) python files. For example:
ipython notebook foo.ipynb
closes#945
This commit lets you open notebook files from the command line, just
like ipython can open (run) python files. For example:
ipython notebook foo.ipynb
Fixes#945.
Resizing to small collapse the pager keeping the size to at least 20%
height
(trying to) resize a collapsed pager to more than 10% "expand" it.
Pager can remember it size when toggling by clicking.
clear In[] prompt numbers on "Clear All Output"
For more version-control-friendly `.ipynb` files, this strips the `In[]` prompt numbers when doing a "Clear all output". This reduces the amount of noise in commit-to-commit diffs that would otherwise show the (highly variable) prompt number changes.
* 2.1.7 (earliest dep) will simply not work, so skip it
* 2.1.9-10 log the interrupts, so add a short delay to ensure the log
messages don't come after the prompt.
rename plaintext cell -> raw cell
Raw cells should be *untransformed* when writing various output formats, as the point of them is to let users pass through IPython to their rendered document format (rst, latex, etc.). This is different from what is the logical meaning of 'plaintext', which would suggest that the contents should be preserved as unformatted plaintext (e.g. in a `<pre>` tag, or literal block).
In the UI, these cells will be displayed as 'Raw Text'.
WARNING: any existing v3 notebooks which use plaintext cells, when read in by versions after this merge, will silently rename those cells to 'raw'. But if such a notebook is uploaded into a pre-merge IPython, cells labeled as 'raw' will simply *not be displayed*.
small changes in response to pyflakes pass
Only significant change: removes incomplete kernelstarter file, which shouldn't have been in the repo at all.
closes#1499
clear_output improvements, which allow things like progress bars and other simple animations to work well in the notebook.
* `clear_output()` clears the line, even in terminal IPython, the QtConsole and plain Python as well, by printing `\r` to streams.
* `clear_output()` avoids the flicker in the notebook by adding a delay, and firing immediately upon the next actual display message.
* `display_javascript` hides its `output_area` element, so using display to run a bunch of javascript doesn't result in ever-growing vertical space.
This reduces flicker during common loops like:
for step in stuff:
clear_output()
print something
the timeout is flushed *immediately* on any subsequent output.
ensures that config loading matches what would happen in ipcluster.
The only change needed in IPClusterStart itself was moving the on_stop registration from init_launchers to start_controller, where it should have been anyway.
* Created new base page html/css/js.
* Everything inherits from the page template.
* Universal header border.
* Notebook list borders are set to 1px all around.
* No border around notebook area.
* Border cleanup of toolbar/menubar.
* Lots of code reorg to get ready for further refactoring.
This exposes ipcluster's over the web. The current implementation
uses IPClusterLauncher to run ipcluster in a separate process.
Here is the URL scheme we are using:
GET /clusters => list available clusters
GET /cluster/profile => list info for cluster with profile
POST /cluster/profile/start => start a cluster
POST /cluster/profile/stop => stop a cluster
Amazon CloudFront (MathJax's CDN) supports HTTPS, but their SSL certificate only applies to *.cloudfront.net urls. This retrieves the cloudfront host at runtime, and loads MathJax from there via HTTPS.
adds new `NotebookApp.browser` configurable and corresponding `--browser` alias for specifying which browser should be launched with the notebook landing page.
Safari still uses draft76, and Tornado 2.2.0 release disables the
access from the draft version by default for security reasons.
This simply sets the tornado flag to True, so we can continue
to support Safari until it upgrades to the RFC 6455 implementation.
Python < 2.6.5 doesn't accept unicode keys in f(**kwargs), and
base_project_url will always be unicode, which will in turn
make the patterns unicode, and ultimately result in unicode
keys in kwargs to handler._execute(**kwargs) in tornado.
This enforces that base_project_url be ascii in that situation.
Note that the URLs these patterns check against are escaped,
and thus guaranteed to be ASCII: 'héllo' is really 'h%C3%A9llo'.
If you actually use u'héllo' in your regex, it will not match the URLs
you think it should.
1. Users are warned when an older nbformat notebook is converted.
2. The notebook notifies the user when a notebook that is too new
is attempted to load.
To test these things, create a simple notebook. Then change its
nbformat field by hand to 2 (to test 1) and then 4 (to test 2).
Pressing TAB to get the tooltip "range(TAB" was inserting a TAB.
To get rid of this we are now telling CodeMirror to ignore it
and also stopping the event from bubbling up the DOM.
