Select something from here. You'll see that the selection's foreground
color changes to white! Since, by default, CodeMirror only puts an
independent "marker" layer behind the text, you'll need something like
this to change its colour.
Also notice that turning this addon on (with the default style) allows
you to safely give text a background color without screwing up the
visibility of the selection.</textarea></form>

<h2>merge view demo</h2>
<div id=view></div>
<p>The <a href="../doc/manual.html#addon_merge"><code>merge</code></a>
addon provides an interface for displaying and merging diffs,
either <span class=clicky onclick="panes = 2; initUI()">two-way</span>
or <span class=clicky onclick="panes = 3; initUI()">three-way</span>.
The left (or center) pane is editable, and the differences with the
other pane(s) are <span class=clicky
onclick="toggleDifferences()">optionally</span> shown live as you edit
it. In the two-way configuration, there are also options to pad changed
sections to <span class=clicky onclick="connect = connect ? null :
'align'; initUI()">align</span> them, and to <span class=clicky
onclick="collapse = !collapse; initUI()">collapse</span> unchanged
stretches of text.</p>
<p>This addon depends on
the <a href="https://code.google.com/p/google-diff-match-patch/">google-diff-match-patch</a>

<p>
The <a href="../doc/manual.html#addon_panel"><code>panel</code></a>
addon allows you to display panels above or below an editor.
<br>
Click the links below to add panels at the given position:
</p>
<div id="demo">
<p>
<a class="add-panel" onclick="addPanel('top')">top</a>
<a class="add-panel" onclick="addPanel('after-top')">after-top</a>
<a class="add-panel" onclick="addPanel('before-bottom')">before-bottom</a>
<a class="add-panel" onclick="addPanel('bottom')">bottom</a>
</p>
<p>
You can also replace an existing panel:
</p>
<form onsubmit="return replacePanel(this);" name="replace_panel">
<input type="submit" value="Replace panel n°" />
<input type="number" name="panel_id" min="1" value="1" />

<h2>Simple Mode Demo</h2>
<p>The <a href="../addon/mode/simple.js"><code>mode/simple</code></a>
addon allows CodeMirror modes to be specified using a relatively simple
declarative format. This format is not as powerful as writing code
directly against the <a href="../doc/manual.html#modeapi">mode
interface</a>, but is a lot easier to get started with, and
sufficiently expressive for many simple language modes.</p>
<p>This interface is still in flux. It is unlikely to be scrapped or
overhauled completely, so do start writing code against it, but
details might change as it stabilizes, and you might have to tweak
your code when upgrading.</p>
<p>Simple modes (loosely based on
the <a href="https://github.com/mozilla/skywriter/wiki/Common-JavaScript-Syntax-Highlighting-Specification">Common
JavaScript Syntax Highlighting Specification</a>, which never took
off), are state machines, where each state has a number of rules that
match tokens. A rule describes a type of token that may occur in the
current state, and possibly a transition to another state caused by
that token.</p>
<p>The <code>CodeMirror.defineSimpleMode(name, states)</code> method
takes a mode name and an object that describes the mode's states. The
editor below shows an example of such a mode (and is itself
highlighted by the mode shown in it).</p>
<div id="code"></div>
<p>Each state is an array of rules. A rule may have the following properties:</p>
<dl>
<dt><code><strong>regex</strong>: string | RegExp</code></dt>
<dd>The regular expression that matches the token. May be a string
or a regex object. When a regex, the <code>ignoreCase</code> flag
will be taken into account when matching the token. This regex
has to capture groups when the <code>token</code> property is
an array. If it captures groups, it must capture <em>all</em> of the string
(since JS provides no way to find out where a group matched).</dd>
<dt><code><strong>token</strong></code>: string | array&lt;string&gt; | null</dt>
<dd>An optional token style. Multiple styles can be specified by
separating them with dots or spaces. When this property holds an array of token styles,
the <code>regex</code> for this rule must capture a group for each array item.
</dd>
<dt><code><strong>sol</strong></code>: boolean</dt>
<dd>When true, this token will only match at the start of the line.
(The <code>^</code> regexp marker doesn't work as you'd expect in
this context because of limitations in JavaScript's RegExp
API.)</dd>
<dt><code><strong>next</strong>: string</code></dt>
<dd>When a <code>next</code> property is present, the mode will
transfer to the state named by the property when the token is
encountered.</dd>
<dt><code><strong>push</strong>: string</code></dt>
<dd>Like <code>next</code>, but instead replacing the current state
by the new state, the current state is kept on a stack, and can be
returned to with the <code>pop</code> directive.</dd>
<dt><code><strong>pop</strong>: bool</code></dt>
<dd>When true, and there is another state on the state stack, will
cause the mode to pop that state off the stack and transition to
it.</dd>
<dt><code><strong>mode</strong>: {spec, end, persistent}</code></dt>
<dd>Can be used to embed another mode inside a mode. When present,
must hold an object with a <code>spec</code> property that describes
the embedded mode, and an optional <code>end</code> end property
that specifies the regexp that will end the extent of the mode. When
a <code>persistent</code> property is set (and true), the nested
mode's state will be preserved between occurrences of the mode.</dd>
<dt><code><strong>indent</strong>: bool</code></dt>
<dd>When true, this token changes the indentation to be one unit
more than the current line's indentation.</dd>
<dt><code><strong>dedent</strong>: bool</code></dt>
<dd>When true, this token will pop one scope off the indentation
stack.</dd>
<dt><code><strong>dedentIfLineStart</strong>: bool</code></dt>
<dd>If a token has its <code>dedent</code> property set, it will, by
default, cause lines where it appears at the start to be dedented.
Set this property to false to prevent that behavior.</dd>
</dl>
<p>The <code>meta</code> property of the states object is special, and
will not be interpreted as a state. Instead, properties set on it will
be set on the mode, which is useful for properties
like <a href="../doc/manual.html#addon_comment"><code>lineComment</code></a>,
which sets the comment style for a mode. The simple mode addon also
recognizes a few such properties:</p>
<dl>
<dt><code><strong>dontIndentStates</strong>: array&lt;string&gt;</code></dt>
<dd>An array of states in which the mode's auto-indentation should
not take effect. Usually used for multi-line comment and string
states.</dd>
</dl>
<script id="modecode">/* Example definition of a simple mode that understands a subset of
* JavaScript:
*/
CodeMirror.defineSimpleMode("simplemode", {
// The start state contains the rules that are intially used
start: [
// The regex matches the token, the token property contains the type
{regex: /"(?:[^\\]|\\.)*?(?:"|$)/, token: "string"},
// You can match multiple tokens at once. Note that the captured
// groups must span the whole string in this case

<p>The <a href="../doc/manual.html#addon_simplescrollbars"><code>simplescrollbars</code></a> addon defines two
styles of non-native scrollbars: <a href="javascript:editor.setOption('scrollbarStyle', 'simple')"><code>"simple"</code></a> and <a href="javascript:editor.setOption('scrollbarStyle', 'overlay')"><code>"overlay"</code></a> (click to try), which can be passed to
the <a href="../doc/manual.html#option_scrollbarStyle"><code>scrollbarStyle</code></a> option. These implement
the scrollbar using DOM elements, allowing more control over
its <a href="../addon/scroll/simplescrollbars.css">appearance</a>.</p>

a <code>spanAffectsWrapping</code> regexp for a browser. See the
comments above that variable

for some more details.</p>
