     5  * Tag-closer extension for CodeMirror.
     6  *
     7  * This extension adds an "autoCloseTags" option that can be set to
     8  * either true to get the default behavior, or an object to further
     9  * configure its behavior.
    10  *
    11  * These are supported options:
    12  *
    13  * `whenClosing` (default true)
    14  *   Whether to autoclose when the '/' of a closing tag is typed.
    15  * `whenOpening` (default true)
    16  *   Whether to autoclose the tag when the final '>' of an opening
    17  *   tag is typed.
    18  * `dontCloseTags` (default is empty tags for HTML, none for XML)
    19  *   An array of tag names that should not be autoclosed.
    20  * `indentTags` (default is block tags for HTML, none for XML)
    21  *   An array of tag names that should, when opened, cause a
    22  *   blank line to be added inside the tag, and the blank line and
    23  *   closing line to be indented.
    24  *
    25  * See demos/closetag.html for a usage example.
