1154 -/**
1155 - * Tag-closer extension for CodeMirror.
1156 - *
1157 - * This extension adds an "autoCloseTags" option that can be set to
1158 - * either true to get the default behavior, or an object to further
1159 - * configure its behavior.
1160 - *
1161 - * These are supported options:
1162 - *
1163 - * `whenClosing` (default true)
1164 - * Whether to autoclose when the '/' of a closing tag is typed.
1165 - * `whenOpening` (default true)
1166 - * Whether to autoclose the tag when the final '>' of an opening
1167 - * tag is typed.
1168 - * `dontCloseTags` (default is empty tags for HTML, none for XML)
1169 - * An array of tag names that should not be autoclosed.
1170 - * `indentTags` (default is block tags for HTML, none for XML)
1171 - * An array of tag names that should, when opened, cause a
1172 - * blank line to be added inside the tag, and the blank line and
1173 - * closing line to be indented.
1174 - *
1175 - * See demos/closetag.html for a usage example.
