<p><strong>CodeMirror</strong> is a versatile text editor
implemented in JavaScript for the browser. It is specialized for
editing code, and comes with a number of <a href="mode/index.html">language modes</a> and <a href="doc/manual.html#addons">addons</a>
that implement more advanced editing functionality.</p>
<p>A rich <a href="doc/manual.html#api">programming API</a> and a
CSS <a href="doc/manual.html#styling">theming</a> system are
available for customizing CodeMirror to fit your application, and
extending it with new functionality.</p>

<h2>Browser support</h2>
<p>The <em>desktop</em> versions of the following browsers,
in <em>standards mode</em> (HTML5 <code>&lt;!doctype html></code>
recommended) are supported:</p>
<table style="margin-bottom: 1em">
<tr><th>Firefox</th><td>version 4 and up</td></tr>
<tr><th>Chrome</th><td>any version</td></tr>
<tr><th>Safari</th><td>version 5.2 and up</td></tr>
<tr><th style="padding-right: 1em;">Internet Explorer/Edge</th><td>version 8 and up</td></tr>
<tr><th>Opera</th><td>version 9 and up</td></tr>
</table>
<p>Support for modern mobile browsers is experimental. Recent
versions of the iOS browser and Chrome on Android should work
pretty well.</p>

<p>Simple mode that tries to handle APL as well as it can.</p>
<p>It attempts to label functions/operators based upon
monadic/dyadic usage (but this is far from fully fleshed out).
This means there are meaningful classnames so hover states can
have popups etc.</p>

[ This program prints "Hello World!" and a newline to the screen, its
length is 106 active command characters [it is not the shortest.]
This loop is a "comment loop", it's a simple way of adding a comment
to a BF program such that you don't have to worry about any command
characters. Any ".", ",", "+", "-", "&lt;" and "&gt;" characters are simply
ignored, the "[" and "]" characters just have to be balanced.
]
+++++ +++ Set Cell #0 to 8
[
&gt;++++ Add 4 to Cell #1; this will always set Cell #1 to 4
[ as the cell will be cleared by the loop
&gt;++ Add 2 to Cell #2
&gt;+++ Add 3 to Cell #3
&gt;+++ Add 3 to Cell #4
&gt;+ Add 1 to Cell #5
&lt;&lt;&lt;&lt;- Decrement the loop counter in Cell #1
] Loop till Cell #1 is zero; number of iterations is 4
&gt;+ Add 1 to Cell #2
&gt;+ Add 1 to Cell #3
&gt;- Subtract 1 from Cell #4
&gt;&gt;+ Add 1 to Cell #6
[&lt;] Move back to the first zero cell you find; this will
be Cell #1 which was cleared by the previous loop
&lt;- Decrement the loop Counter in Cell #0
] Loop till Cell #0 is zero; number of iterations is 8
The result of this is:
Cell No : 0 1 2 3 4 5 6
Contents: 0 0 72 104 88 32 8
Pointer : ^
&gt;&gt;. Cell #2 has value 72 which is 'H'
&gt;---. Subtract 3 from Cell #3 to get 101 which is 'e'
+++++++..+++. Likewise for 'llo' from Cell #3
&gt;&gt;. Cell #5 is 32 for the space
&lt;-. Subtract 1 from Cell #4 for 87 to give a 'W'
&lt;. Cell #3 was set to 'o' from the end of 'Hello'
+++.------.--------. Cell #3 for 'rl' and 'd'
&gt;&gt;+. Add 1 to Cell #5 gives us an exclamation point
&gt;++. And finally a newline from Cell #6

/** A template trait for traversable collections of type `Traversable[A]`.
*
* $traversableInfo
* @define mutability
* @define traversableInfo
* This is a base trait of all kinds of $mutability Scala collections. It
* implements the behavior common to all collections, in terms of a method
* `foreach` with signature:
* {{{
* def foreach[U](f: Elem => U): Unit
* }}}
* Collection classes mixing in this trait provide a concrete
* `foreach` method which traverses all the
* elements contained in the collection, applying a given function to each.
* They also need to provide a method `newBuilder`
* which creates a builder for collections of the same kind.
*
* A traversable class might or might not have two properties: strictness
* and orderedness. Neither is represented as a type.
*
* The instances of a strict collection class have all their elements
* computed before they can be used as values. By contrast, instances of
* a non-strict collection class may defer computation of some of their
* elements until after the instance is available as a value.
* A typical example of a non-strict collection class is a
* <a href="../immutable/Stream.html" target="ContentFrame">
* `scala.collection.immutable.Stream`</a>.
* A more general class of examples are `TraversableViews`.
*
* If a collection is an instance of an ordered collection class, traversing
* its elements with `foreach` will always visit elements in the
* same order, even for different runs of the program. If the class is not
* ordered, `foreach` can visit elements in different orders for
* different runs (but it will keep the same order in the same run).'
*
* A typical example of a collection class which is not ordered is a
* `HashMap` of objects. The traversal order for hash maps will
* depend on the hash codes of its elements, and these hash codes might
* differ from one run to the next. By contrast, a `LinkedHashMap`
* is ordered because it's `foreach` method visits elements in the
* order they were inserted into the `HashMap`.
