// About: Examples
//
// These working examples, complete with fully commented code, illustrate a few
// ways in which this plugin can be used.
//
// Debouncing - http://benalman.com/code/projects/jquery-dotimeout/examples/debouncing/
// Delays, Polling - http://benalman.com/code/projects/jquery-dotimeout/examples/delay-poll/
// Hover Intent - http://benalman.com/code/projects/jquery-dotimeout/examples/hoverintent/
//
// About: Support and Testing
//
// Information about what version or versions of jQuery this plugin has been
// tested with, what browsers it has been tested in, and where the unit tests
// reside (so you can test it yourself).
//
// jQuery Versions - 1.3.2, 1.4.2
// Browsers Tested - Internet Explorer 6-8, Firefox 2-3.6, Safari 3-4, Chrome 4-5, Opera 9.6-10.1.
// Unit Tests - http://benalman.com/code/projects/jquery-dotimeout/unit/
//
// About: Release History
//
// 1.0 - (3/3/2010) Callback can now be a string, in which case it will call
// the appropriate $.method or $.fn.method, depending on where .doTimeout
// was called. Callback must now return `true` (not just a truthy value)
// to poll.
// 0.4 - (7/15/2009) Made the "id" argument optional, some other minor tweaks
// 0.3 - (6/25/2009) Initial release

doTimeout = 'doTimeout',
// A convenient shortcut.
aps = Array.prototype.slice;
// Method: jQuery.doTimeout
//
// Initialize, cancel, or force execution of a callback after a delay.
//
// If delay and callback are specified, a doTimeout is initialized. The
// callback will execute, asynchronously, after the delay. If an id is
// specified, this doTimeout will override and cancel any existing doTimeout
// with the same id. Any additional arguments will be passed into callback
// when it is executed.
//
// If the callback returns true, the doTimeout loop will execute again, after
// the delay, creating a polling loop until the callback returns a non-true
// value.
//
// Note that if an id is not passed as the first argument, this doTimeout will
// NOT be able to be manually canceled or forced. (for debouncing, be sure to
// specify an id).
//
// If id is specified, but delay and callback are not, the doTimeout will be
// canceled without executing the callback. If force_mode is specified, the
// callback will be executed, synchronously, but will only be allowed to
// continue a polling loop if force_mode is true (provided the callback
// returns true, of course). If force_mode is false, no polling loop will
// continue, even if the callback returns true.
//
// Usage:
//
// > jQuery.doTimeout( [ id, ] delay, callback [, arg ... ] );
// > jQuery.doTimeout( id [, force_mode ] );
//
// Arguments:
//
// id - (String) An optional unique identifier for this doTimeout. If id is
// not specified, the doTimeout will NOT be able to be manually canceled or
// forced.
// delay - (Number) A zero-or-greater delay in milliseconds after which
// callback will be executed.
// callback - (Function) A function to be executed after delay milliseconds.
// callback - (String) A jQuery method to be executed after delay
// milliseconds. This method will only poll if it explicitly returns
// true.
// force_mode - (Boolean) If true, execute that id's doTimeout callback
// immediately and synchronously, continuing any callback return-true
// polling loop. If false, execute the callback immediately and
// synchronously but do NOT continue a callback return-true polling loop.
// If omitted, cancel that id's doTimeout.
//
// Returns:
//
// If force_mode is true, false or undefined and there is a
// yet-to-be-executed callback to cancel, true is returned, but if no
// callback remains to be executed, undefined is returned.
$[doTimeout] = function() {
return p_doTimeout.apply( window, [ 0 ].concat( aps.call( arguments ) ) );
};
// Method: jQuery.fn.doTimeout
//
// Initialize, cancel, or force execution of a callback after a delay.
// Operates like <jQuery.doTimeout>, but the passed callback executes in the
// context of the jQuery collection of elements, and the id is stored as data
// on the first element in that collection.
//
// If delay and callback are specified, a doTimeout is initialized. The
// callback will execute, asynchronously, after the delay. If an id is
// specified, this doTimeout will override and cancel any existing doTimeout
// with the same id. Any additional arguments will be passed into callback
// when it is executed.
//
// If the callback returns true, the doTimeout loop will execute again, after
// the delay, creating a polling loop until the callback returns a non-true
// value.
//
// Note that if an id is not passed as the first argument, this doTimeout will
// NOT be able to be manually canceled or forced (for debouncing, be sure to
// specify an id).
//
// If id is specified, but delay and callback are not, the doTimeout will be
// canceled without executing the callback. If force_mode is specified, the
// callback will be executed, synchronously, but will only be allowed to
// continue a polling loop if force_mode is true (provided the callback
// returns true, of course). If force_mode is false, no polling loop will
// continue, even if the callback returns true.
//
// Usage:
//
// > jQuery('selector').doTimeout( [ id, ] delay, callback [, arg ... ] );
// > jQuery('selector').doTimeout( id [, force_mode ] );
//
// Arguments:
//
// id - (String) An optional unique identifier for this doTimeout, stored as
// jQuery data on the element. If id is not specified, the doTimeout will
// NOT be able to be manually canceled or forced.
// delay - (Number) A zero-or-greater delay in milliseconds after which
// callback will be executed.
// callback - (Function) A function to be executed after delay milliseconds.
// callback - (String) A jQuery.fn method to be executed after delay
// milliseconds. This method will only poll if it explicitly returns
// true (most jQuery.fn methods return a jQuery object, and not `true`,
// which allows them to be chained and prevents polling).
// force_mode - (Boolean) If true, execute that id's doTimeout callback
// immediately and synchronously, continuing any callback return-true
// polling loop. If false, execute the callback immediately and
// synchronously but do NOT continue a callback return-true polling loop.
// If omitted, cancel that id's doTimeout.
//
// Returns:
//
// When creating a <jQuery.fn.doTimeout>, the initial jQuery collection of
// elements is returned. Otherwise, if force_mode is true, false or undefined
// and there is a yet-to-be-executed callback to cancel, true is returned,
// but if no callback remains to be executed, undefined is returned.

* Splits a string into an array of strings using a regex or string

* @param {String} str String to split.
* @param {RegExp} separator Regex to use for separating
* the string.
* @param {Number} [limit] Maximum number of items to include in the result
* array.
* @returns {Array} Array of substrings.
* @example
*
* // Basic use
* regex_split('a b c d', ' ');
* // -> ['a', 'b', 'c', 'd']
*
* // With limit
* regex_split('a b c d', ' ', 2);
* // -> ['a', 'b']

/*
How Properties of Mime Types are used by SQL Mode
=================================================
keywords:
A list of keywords you want to be highlighted.
builtin:
A list of builtin types you want to be highlighted (if you want types to be of class "builtin" instead of "keyword").
operatorChars:
All characters that must be handled as operators.
client:
Commands parsed and executed by the client (not the server).
support:
A list of supported syntaxes which are not common, but are supported by more than 1 DBMS.
* ODBCdotTable: .tableName
* zerolessFloat: .1
* doubleQuote
* nCharCast: N'string'
* charsetCast: _utf8'string'
* commentHash: use # char for comments
* commentSlashSlash: use // for comments
* commentSpaceRequired: require a space after -- for comments
atoms:
Keywords that must be highlighted as atoms,. Some DBMS's support more atoms than others:
UNKNOWN, INFINITY, UNDERFLOW, NaN...
dateSQL:
Used for date/time SQL standard syntax, because not all DBMS's support same temporal types.

/**
*
*
* Placeholder for custom user javascript
* mainly to be overridden in profile/static/custom/custom.js
* This will always be an empty file in IPython
*
* User could add any javascript in the `profile/static/custom/custom.js` file
* (and should create it if it does not exist).
* It will be executed by the ipython notebook at load time.
*
* Same thing with `profile/static/custom/custom.css` to inject custom css into the notebook.
*
* Classes and functions are available at load time and may be accessed plainly:
*
* IPython.Cell.options_default.cm_config.extraKeys['Home'] = 'goLineLeft';
* IPython.Cell.options_default.cm_config.extraKeys['End'] = 'goLineRight';
*
* Instances are created later however and must be accessed using events:
* require([
* 'base/js/namespace',
* 'base/js/events'
* ], function(IPython, events) {
* events.on("app_initialized.NotebookApp", function () {
* IPython.keyboard_manager....
* });
* });
*
* __Example 1:__
*
* Create a custom button in toolbar that execute `%qtconsole` in kernel
* and hence open a qtconsole attached to the same kernel as the current notebook
*
* require([
* 'base/js/namespace',
* 'base/js/events'
* ], function(IPython, events) {
* events.on('app_initialized.NotebookApp', function(){
* IPython.toolbar.add_buttons_group([
* {
* 'label' : 'run qtconsole',
* 'icon' : 'icon-terminal', // select your icon from http://fortawesome.github.io/Font-Awesome/icons
* 'callback': function () {
* IPython.notebook.kernel.execute('%qtconsole')
* }
* }
* // add more button here if needed.
* ]);
* });
* });
*
* __Example 2:__
*
* At the completion of the dashboard loading, load an unofficial javascript extension
* that is installed in profile/static/custom/
*
* require([
* 'base/js/events'
* ], function(events) {
* events.on('app_initialized.DashboardApp', function(){
* require(['custom/unofficial_extension.js'])
* });
* });
*
* __Example 3:__
*
* Use `jQuery.getScript(url [, success(script, textStatus, jqXHR)] );`
* to load custom script into the notebook.
*
* // to load the metadata ui extension example.
* $.getScript('/static/notebook/js/celltoolbarpresets/example.js');
* // or
* // to load the metadata ui extension to control slideshow mode / reveal js for nbconvert
* $.getScript('/static/notebook/js/celltoolbarpresets/slideshow.js');
*
*
* @module IPython
* @namespace IPython
* @class customjs
* @static
