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.
* 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.
