<h1>CodeMirror: Closebrackets Demo</h1>
|
|
|
|
|
|
<p>Type a bracket like '[', '(', '{', '"', or '''
|
|
|
and <a href="../doc/manual.html#addon_closebrackets">the addon</a>
|
|
|
will auto-close it. Type the closing variant when directly in
|
|
|
front of a matching character and it will overwrite it.</p>
|
|
|
|
|
|
<p>If you backspace over a starting bracket while inside empty brackets
|
|
|
(e.g. <code>{|}</code>), it will delete the closing bracket for you.</p>
