-/* Upgrading to
- version 3 */
-</pre>
-</div>
-
-<div class="clear"><div class="leftbig blk">
-
-<p>Version 3 does not depart too much from 2.x API, and sites that use
-CodeMirror in a very simple way might be able to upgrade without
-trouble. But it does introduce a number of incompatibilities. Please
-at least skim this text before upgrading.</p>
-
-<p>Note that <strong>version 3 drops full support for Internet
-Explorer 7</strong>. The editor will mostly work on that browser, but
-it'll be significantly glitchy.</p>
-
-<h2 id=dom>DOM structure</h2>
-
-<p>This one is the most likely to cause problems. The internal
-structure of the editor has changed quite a lot, mostly to implement a
-new scrolling model.</p>
-
-<p>Editor height is now set on the outer wrapper element (CSS
-class <code>CodeMirror</code>), not on the scroller element
-(<code>CodeMirror-scroll</code>).</p>
-
-<p>Other nodes were moved, dropped, and added. If you have any code
-that makes assumptions about the internal DOM structure of the editor,
-you'll have to re-test it and probably update it to work with v3.</p>
-
-<p>See the <a href="manual.html#styling">styling section</a> of the
-manual for more information.</p>
-
-<h2 id=gutters>Gutter model</h2>
-
-<p>In CodeMirror 2.x, there was a single gutter, and line markers
-created with <code>setMarker</code> would have to somehow coexist with
-the line numbers (if present). Version 3 allows you to specify an
-array of gutters, <a href="manual.html#option_gutters">by class
-name</a>,
-use <a href="manual.html#setGutterMarker"><code>setGutterMarker</code></a>
-to add or remove markers in individual gutters, and clear whole
-gutters
-with <a href="manual.html#clearGutter"><code>clearGutter</code></a>.
-Gutter markers are now specified as DOM nodes, rather than HTML
-snippets.</p>
-
-<p>The gutters no longer horizontally scrolls along with the content.
-The <code>fixedGutter</code> option was removed (since it is now the
-only behavior).</p>
-
-<pre data-lang="text/html">
-<style>
- /* Define a gutter style */
- .note-gutter { width: 3em; background: cyan; }
-</style>
-<script>
- // Create an instance with two gutters -- line numbers and notes
- var cm = new CodeMirror(document.body, {
- gutters: ["note-gutter", "CodeMirror-linenumbers"],
- lineNumbers: true
- });
- // Add a note to line 0
- cm.setGutterMarker(0, "note-gutter", document.createTextNode("hi"));
-</script>
-</pre>
-
-<h2 id=events>Event handling</h2>
-
-<p>Most of the <code>onXYZ</code> options have been removed. The same
-effect is now obtained by calling
-the <a href="manual.html#on"><code>on</code></a> method with a string
-identifying the event type. Multiple handlers can now be registered
-(and individually unregistered) for an event, and objects such as line
-handlers now also expose events. See <a href="manual.html#events">the
-full list here</a>.</p>
-
-<p>(The <code>onKeyEvent</code> and <code>onDragEvent</code> options,
-which act more as hooks than as event handlers, are still there in
-their old form.)</p>
-
-<pre data-lang="javascript">
-cm.on("change", function(cm, change) {
- console.log("something changed! (" + change.origin + ")");
-});
-</pre>
-
-<h2 id=marktext>markText method arguments</h2>
-
-<p>The <a href="manual.html#markText"><code>markText</code></a> method
-(which has gained some interesting new features, such as creating
-atomic and read-only spans, or replacing spans with widgets) no longer
-takes the CSS class name as a separate argument, but makes it an
-optional field in the options object instead.</p>
-
-<pre data-lang="javascript">
-// Style first ten lines, and forbid the cursor from entering them
-cm.markText({line: 0, ch: 0}, {line: 10, ch: 0}, {
- className: "magic-text",
- inclusiveLeft: true,
- atomic: true
-});
-</pre>
-
-<h2 id=folding>Line folding</h2>
-
-<p>The interface for hiding lines has been
-removed. <a href="manual.html#markText"><code>markText</code></a> can
-now be used to do the same in a more flexible and powerful way.</p>
-
-<p>The <a href="../demo/folding.html">folding script</a> has been
-updated to use the new interface, and should now be more robust.</p>
-
-<pre data-lang="javascript">
-// Fold a range, replacing it with the text "??"
-var range = cm.markText({line: 4, ch: 2}, {line: 8, ch: 1}, {
- replacedWith: document.createTextNode("??"),
- // Auto-unfold when cursor moves into the range
- clearOnEnter: true
-});
-// Get notified when auto-unfolding
-CodeMirror.on(range, "clear", function() {
- console.log("boom");
-});
-</pre>
-
-<h2 id=lineclass>Line CSS classes</h2>
-
-<p>The <code>setLineClass</code> method has been replaced
-by <a href="manual.html#addLineClass"><code>addLineClass</code></a>
-and <a href="manual.html#removeLineClass"><code>removeLineClass</code></a>,
-which allow more modular control over the classes attached to a line.</p>
-
-<pre data-lang="javascript">
-var marked = cm.addLineClass(10, "background", "highlighted-line");
-setTimeout(function() {
- cm.removeLineClass(marked, "background", "highlighted-line");
-});
-</pre>
-
-<h2 id=positions>Position properties</h2>
-
-<p>All methods that take or return objects that represent screen
-positions now use <code>{left, top, bottom, right}</code> properties
-(not always all of them) instead of the <code>{x, y, yBot}</code> used
-by some methods in v2.x.</p>
-
-<p>Affected methods
-are <a href="manual.html#cursorCoords"><code>cursorCoords</code></a>, <a href="manual.html#charCoords"><code>charCoords</code></a>, <a href="manual.html#coordsChar"><code>coordsChar</code></a>,
-and <a href="manual.html#getScrollInfo"><code>getScrollInfo</code></a>.</p>
-
-<h2 id=matchbrackets>Bracket matching no longer in core</h2>
-
-<p>The <a href="manual.html#addon_matchbrackets"><code>matchBrackets</code></a>
-option is no longer defined in the core editor.
-Load <code>addon/edit/matchbrackets.js</code> to enable it.</p>
-
-<h2 id=modes>Mode management</h2>
-
-<p>The <code>CodeMirror.listModes</code>
-and <code>CodeMirror.listMIMEs</code> functions, used for listing
-defined modes, are gone. You are now encouraged to simply
-inspect <code>CodeMirror.modes</code> (mapping mode names to mode
-constructors) and <code>CodeMirror.mimeModes</code> (mapping MIME
-strings to mode specs).</p>
-
-<h2 id=new>New features</h2>
-
-<p>Some more reasons to upgrade to version 3.</p>
-
-<ul>
- <li>Bi-directional text support. CodeMirror will now mostly do the
- right thing when editing Arabic or Hebrew text.</li>
- <li>Arbitrary line heights. Using fonts with different heights
- inside the editor (whether off by one pixel or fifty) is now
- supported and handled gracefully.</li>
- <li>In-line widgets. See <a href="../demo/widget.html">the demo</a>
- and <a href="manual.html#addLineWidget">the docs</a>.</li>
- <li>Defining custom options
- with <a href="manual.html#defineOption"><code>CodeMirror.defineOption</code></a>.</li>
