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
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
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.
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*.
This reduces flicker during common loops like:
for step in stuff:
clear_output()
print something
the timeout is flushed *immediately* on any subsequent output.
* 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.
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!
We have fixed some of the problems with CodeMirror and feel that
the differences between Ace and CodeMirror are not great enough
to justify having both. We may reintroduce a full-window edit
mode using CodeMirror, but that will come separately.
somwhere in renaming `selected_cell` to `get_selected_cell` one
occurence has been forgoten in `codecell.js` this was mainly visible by
the fact that the 'show pager' button of the tooltip was non fonctionnal
anymore.
* 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.
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.
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 `()[]./\-+`
for the moment. usefull for exaple when typing :
>>> np.s<tab>in(
and not having to type '(' twice.
they are handle separately has the [a-zA-Z] ones because otherwise they
will screw up the regexp, and are opt-in to avoid bugs with invisible
caracters send because some browser have 'keypress' event for meta keys
close#1080
Note to this commit :
list of test for the completer across browser with --pylab=inline flag
#test direct one completion
plt.an<tab> -> plt.annotate
#test filter,tab, only one completion
plt.a<tab>n<tab> -> plt.annotate
# test partial common beggining
# test dismmised if user erase
plt.a<tab>nn<backspace><backspace>u<tab> -> completer to `aut`
........................................<tab><tab><tab> -> nothing should append
.......................................................<backspace><backspace<backspace> -> completer cancelled
#test dismiss if no more completion
plt.s<tab>c -> completer 3 choices
...........u -> dismissed whith what user have typed. `plt.scu`
# test dismiss in no completion, special symbol
# opt-in list of caracters +-/\()[].
np<tab>.s -> a 'dot' sould dismiss the completer and be appended
.........<tab>in( -> np.sin(
np.s<tab>in[ -> np.sin[
allow the notebook to run without MathJax
adds --no-mathjax flag for disabling mathjax, and moves the mathjax URL decision to the server from the browser.
closes#1071
prototype functions were actually called which should not happen, and
resulted in objects and their attributes being passed to their own methods
as arguments.
* use jQuery syntax to construct dialog
* server determines where MathJax comes from via mathjax_url configurable (default local/CDN priority unchanged)
* add `--no-mathjax` flag for disabling mathjax in the notebook server
* A jQuery dialog with our 'no mathjax' message will appear if mathjax is unavailable, but the notebook will be fully functional after dismissal.
* Various calls to MathJax.Hub.typeset moved to Cell.typeset, which checks for MathJax existence and is a no-op without it.
closes#1071
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
the kernel. Then tooltip with 'definition' and beggining of 'docstring'
shown to the user if non empty response.
Unlike Completion <select> , <div> is not focusable so event handled in main
cell event handeling function
Add some CSS3 that most browser with websocket should support.
An error would previously be raised whenever iopub traffic arrived that
did not originate with the notebook (e.g. pylab welcome, or qtconsole output).
This error was not in a block that would actually cause problems, so actual
functionality was not affected.
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.
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.
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.
closes#436
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.
