add FileFindHandler for Notebook static files
* The static file handler now uses a search path, instead of a single dir.
This allows easier customization of available js/css,
and provides a place for extra files to go for extending the notebook.
* An empty custom.js / custom.css are added to the templates for trivial
custom user styling/scripting.
The search only happens once, and the result is cached after the first.
* A few methods are pulled from tornado 2.2-dev verbatim to have tornado 2.1 compatibility.
* mathjax is now installed by default in profile.
win32 iptest: Use subprocess.Popen() instead of os.system().
The call to `os.system` in `iptest` prevents us from easily setting `$IPYTHONDIR` to a temporary directory. In theory we should be able to use `subprocess.Popen` instead of `os.system` in Windows. This would unify the code structure and make it easy to pass in a different environment.
Note that Python < 2.7 does not have `os.kill`. I've attempted to work around this by using `ctypes` to kill any living processes.

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

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.

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.

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*.

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

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.

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.
* Refactored the save widget so that the notebook doesn't depend
on it. Now the notebook emits events and the save widget
observes those events.
* Created a new event system for all IPython events (events.js).
We should start to use this to allow our classes to be loosely
coupled.
* Created a new notification widget that should be used for all
notifications. Uses new event system.
* Removed the kernel status widget.
* All kernel status message use new event/notification system.
* The print notebook view works again.
* json separator is not ',' to avoid adding extra space at EOL.
* vs used throughout nbformat.current.
* Cell collapse is properly loaded from notebook.
Make Control-S (or Cmd-S on Apple) save the actual notebook instead of bringing up the useless 'save as html' dialog. This doesn't disable the C-m-s keybinding, simply adds the far more familiar and common C-s.
We are adding a thin horizontal toolbar below the menubar. This
commit adds the basic UI elements. Still need to hook up the actions
and make this hidable.
The notebook js transforms ANSI-escaped text to HTML. The transformed HTML was previously persisted to ipynb files, rather than the true output. This has been fixed, and notebooks with ANSI-colored output will need to be re-run for colored output (tracebacks) to be displayed correctly after this change.
Updating CodeMirror to the latest dev master.
We had found a bug in CodeMirror that was forcing us to call refresh/focus/refresh on Firefox. This bug was fixed upstream. This PR pull in the latest CM with the bug fix and removes the extra refresh calls. All known CM bugs should be fixed, yeh!
Removing Ace edit capability.
We have fixed some of the problems with CodeMirror and feel that
the differences between Ace and CodeMirror are not great enough

This updates CodeMirror and refactors a good bit of the notebook code related to it.
* Updated CodeMirror to the latest stable release.
* Fix numerous bugs related to the CM update.
* Refactored the Cell API and the notebook's cell handling methods.
* Generalized split/merge to work with all cell types.
* Generalized "Edit in Ace" to work with all cell types.
* Loading optimizations: pager starts out hidden, faster loads.
* Shading added to Markdown and HTML cells when they are being edited.
* This branch will require solid usability testing on Safari, FF and Chrome before merging.
* Fixed a number of CM related bugs.
* Merge/split works for all cell types.
* Notebook.select won't select an already selected cell.
* Bugs in markdown cell editing fixed.
* border-box-sizing used for Markdown cells to get correct css boxes.
* Shading/border added to Markdown cell editor.
* Cell insertion code completely rewritten. We now have two methods
rather than 9: insert_cell_above, insert_cell_below.
* Renaming methods to be more consistent.
* Creating new methods to provide a uniform API.
* Minor bug fixes.
* Added placeholder to the base Cell class.
* Removed the \u0000 char at the beginning of the TextCell
placeholder that was there for a CodeMirror bug workaround.
* Other refactoring of Cell related Notebook methods.
* Added set_text/get_text in favor of get_code/set_code and
get_source/set_source.
* Added methods to the base class (get_text, set_text, refresh,
edit, render, toJSON, fromJSON).
When enabling paste, I was adding the click callback multiple
times causing paste to overwrite multiple cells. I also found
a bug that was doing paste above instead of paste below.
* QuickHelp button has been removed in favor of a Help menu item.
* Keyboard shortcuts are now in the menus.
* Numerous fixes to subtle aspects of the wijmenu implementation.
* edit text cells on double-click instead of single-click
* render text cells on unselect instead of focusout.
Only renders when selecting another cell, and prevents rendering when
switching applications/windows/tabs.
Single-click to edit gets in the way of using interactive elements (e.g. non-flash videos),
and select/copy of the rendered HTML. Switching to double-click makes the edit action more intentional.
adds AuthenticatedFileHandler, which extends StaticFileHandler with
a simple authentication check before providing access to files local
to the notebook dir.
Heartbeats start immediately, causing false heart failures on slow systems that can take a while to start kernel subprocesses.
Also adds a 'flush' to the heartbeat callback (just like in IPython.parallel), to protect against server load being detected as heart failures.
Kernels would not linger, but the KernelManagers are not garbage-collected on shutdown.
This means that connection files for kernels still running at notebook shutdown would not be removed.
Also disable the unnecessary (and actively unhelpful) SIGINT handler inherited from the original
copy/paste from the qt app.

Following @fperez advice, change the completer apparence to avoid user confusion.
- Append what the user type in the completer in code-miror, (Almost) as if
codemirror still have focus
- distinguish between "fixed" completion part, which was sent to the kernel
(now written in bold) and filtering one,handled only in JS,that the user
can errase without dismissing the completer
I changed the action of <Space> to dismiss the completer with what have
already been typed and inserting a space instead of "picking" the currently
hilighted option
<Escape> will still dissmiss the completer and remove everything the user as
typed since the completer invocation
Note that while the completer is shown, code-mirror does not show any
blinking cursor
- dissmiss the completer, append what alredy type, **Plus** one caracter in
some cases
List of special caracter that are handle are in a given list `()[]./\-+`

when invoking the completer, instead of having to chose/dismiss, you can
continue typing, it will filter the result "as you type" and dismiss itself
if ther is no match left.
As it is now, it's only works with lowercase letters, I need to find a workaroud
for this.
for example
if you type :
* P-y-<tab>-S-o-m-e-t-h-i-n-g
* it will propose PySide, but will dismiss when 'o' is pressed and pasting Pyso with a lower case 's'
if completer get only one match back and the user press tab n time,
it fallbacks on showing a tooltip
n=2 , hard coded for know, and completer verbose on the command line
put "close" and "more..." button in upper right corner,
rename "more..." to "open in pager", add expand button.
tooltip don't have scroll bar an are 'small' until pressing "Expand"
they then change their height and add scrollbars.
Horizontal scrollbar behaviour seem to depend on the browser
>>> plot(<tab> and then click on "expand" :
Firefox : no horizontal scrollbar (wrap line ?)
Chrome : horizontal scrollbar
beware that don't limitting tooltip height or width through css will sometime give
tooltip that are too heigh and will overflow below the bottom of the screen
animation are broken with max-height and/or min-height
change order of completion element so that the ones ending with '='
will be at the beginning of the list. When you complete inside a
fonction call, you then have kwargs first add configuration in the left
pannel
add a section in the left pannel of the notebook to make the time before
triggering a tooltip when pressign "(" configurable. Negative values will
disable the tooltip (comparaison at each keypress for now, but can be
improved) The syle of the <input> field should be a little improve, why not
a slider with jquerry
As until now, when pressing tab and a white space was preceding the cursor
The completion was triggerd with the whole namespace in it. Now if a
whitespace or an opening bracket is just befor the cursor it will try to
display a tooltip. The logic to find what object_info_request is send have
been sightly changed to try to match the expression just before the last
unmached openig bracket before the cursor (without considering what is
after the cursor).
example (_|_ represent the cursor):
>>> his_|_<tab> # completion
>>> hist(_|_<tab> # tooltip on hist
>>> hist(rand(20),bins=range(_|_ <tab> #tooltip on range
>>> hist(rand(20),bins=range(10), _|_ <tab> # tooltip on hist (whitespace before cursor)
>>> hist(rand(20),bins=range(10),_|_ <tab> # completion
as we dont care of what is after the cursor:
>>> hist(rand(5000), bins=50, _|_orientaion='horizontal') # and tab, equivalent to
>>> hist(rand(5000), bins=50, _|_<tab> # onte the space again
>>> hist(_|_rand(5000), bins=50, orientaion='horizontal') # and tab, equivalent to
>>> hist(_|_
the 4 give tooltip on hist
note that you can get tooltip on things that aren't function by appending a
'(' like
>>> matplotlib(<tab>
Which is kinda weird... so we might want to bound another shortcut for
tooltip, but which matches without bracket...
additionnaly I have added a "Config" pannel in the left pannel with a checkbox
bind to wether or not activate this functionnality
Note, (rebase and edited commit, might not work perfetly xwithout the following ones)
When user press '(' and nothing for 1200ms, 'object_info_request' sent to

Websocket fixes:
1. alert client on failed and lost web socket connections
A long message is given if the connection fails within 1s, which assumes the connection did not succeed. Otherwise, it is a short 'connection closed unexpectedly'.
This also means that clients are notified on server termination (for better or worse).
2. remove superfluous ws-hostname parameter from notebook
This made the notebook server artificially and unnecessarily brittle against tunneling and explicit hostname resolution. Now, the ws_url is defined based on the Origin of the request for the url, so it always matches the http[s] url. This means that it will follow the same tunnel, and the hostname will be already resolved. Resolving the hostname twice makes no sense at all unless the websockets are going to a different server than the http requests.
Implemented as a property, so it should still be easy to change for future cases where it might behave differently (e.g. websockets on a different host, or at a non-root url).
A long message is given if the connection fails within 1s. Otherwise, it is a short 'connection closed unexpectedly'.
This also means that clients are notified on server termination.
This made the notebook server artificially and unnecessarily brittle to tunneling, and non-local hostname resolution. The ws_url is now defined based on the Origin of the request. This allows tunneled hosts and ports to preserve connections, as the ws_url always matches the one in use by the client.
Implemented as a property, to facilitate future cases where it might behave differently.
The notebook now supports a `--read-only` flag, which allows users to view all notebooks being served but not to edit them or execute any code. These actions are not allowed and the buttons, shortcuts, etc. are removed, but the requests will raise authentication errors if they manage to send the events anyway. Save/print functions remain available.
This flag can be used in two modes:
1. When running an unauthenticated server, one can run a *second* read-only server in the same directory on a public IP address. This will let users connect to the read-only view without having to worry about configuring passwords and certificates for the execution server.
2. When running a server configured with authentication (and hopefully an SSL certificate), starting it with `--read-only` allows unauthenticated users read-only access to notebooks. This means that the same server on a single port can be both used by authenticated users for execution and by the public for viewing the available notebooks.
Show invalid config message on TraitErrors during initialization.
implemented via `@catch_config` decorator
Now, the event that was triggered by invalid app config (see `--log-level 5`) is triggered by bad config at any point during initialization.
This *will* catch TraitError-raising bugs in IPython itself, but only during initialization.
Also, deregister crash handler on use to avoid it being triggered recursively/repeatedly.
If a user has Chrome set as their default browser (system-wide or via
the `BROWSER` environment variable), opening the notebook hangs
because the chrome call doesn't return immediately. This solves the
issue by opening the browser in a thread.
Note that there remains an issue where killing the notebook will kill
Chrome if the Chrome session was started by us. I haven't found a way
to work around that despite attempts by making the webbrowser.open()
call in a subprocess.
When using a password, read-only mode allows unauthenticated users
read-only access to notebooks. Editing, execution, etc. are not
allowed in read-only mode, but save/print functions are available.
No kernels are started until an authenticated user opens a notebook.
implemented via @catch_config decorator
Now, the event that was triggered by invalid app config (see `--log-level 5`) is triggered by bad config at any point during initialization.
This *will* catch TraitError bugs in IPython itself, but only during initialization.

The History will always appear empty, so history magics, etc. don't do anything. Readline history for a single session works fine.
Test suite should now pass without sqlite
Adding clear_output to kernel and HTML notebook.
This enables the clearing of output during the execution of a cell. It can be used for simple forms of animation in the notebook.
All buttons, show/hide clickable areas, etc. should have some tooltip describing
what they do. There are jQuery plugins for enhanced tooltips, but this gets
the lightest version working.

Various Notebook usability fixes:
- add kernel restart dialog confirmation (it destroys the user session)
- add missing keybindings
- change language from 'terminal mode' to 'in-place execution' which is more descriptive
- adjust spacing/padding and colors slightly for readability and better use of space in small screens.
- add line numbering toggle to code cells. Triggered with C-m-l.
- show keybindings in monospaced font.
- add QuickHelp button that is always visible and at the top.
- add missing keybindings for kernel interrupt/restart from the kbd.
Now multiple calls no longer show multiple instances of the shortcut dialog. Rather, clicking the quick help, or invoking `C-m h` will hide
the dialog if shown.
