1/**
2 * Tag-closer extension for CodeMirror.
3 *
4 * This extension adds a "closeTag" utility function that can be used with key bindings to
5 * insert a matching end tag after the ">" character of a start tag has been typed. It can
6 * also complete "</" if a matching start tag is found. It will correctly ignore signal
7 * characters for empty tags, comments, CDATA, etc.
8 *
9 * The function depends on internal parser state to identify tags. It is compatible with the
10 * following CodeMirror modes and will ignore all others:
11 * - htmlmixed
12 * - xml
13 * - xmlpure
14 *
15 * See demos/closetag.html for a usage example.
16 *
17 * @author Nathan Williams <nathan@nlwillia.net>
18 * Contributed under the same license terms as CodeMirror.
