-/**
- * Tag-closer extension for CodeMirror.
- *
- * This extension adds an "autoCloseTags" option that can be set to
- * either true to get the default behavior, or an object to further
- * configure its behavior.
- *
- * These are supported options:
- *
- * `whenClosing` (default true)
- * Whether to autoclose when the '/' of a closing tag is typed.
- * `whenOpening` (default true)
- * Whether to autoclose the tag when the final '>' of an opening
- * tag is typed.
- * `dontCloseTags` (default is empty tags for HTML, none for XML)
- * An array of tag names that should not be autoclosed.
- * `indentTags` (default is block tags for HTML, none for XML)
- * An array of tag names that should, when opened, cause a
- * blank line to be added inside the tag, and the blank line and
- * closing line to be indented.
- *
- * See demos/closetag.html for a usage example.
