* Tag-closer extension for CodeMirror. |
| 1153 |
* |
| 1154 |
* This extension adds an "autoCloseTags" option that can be set to |
| 1155 |
* either true to get the default behavior, or an object to further |
| 1156 |
* configure its behavior. |
| 1157 |
* |
| 1158 |
* These are supported options: |
| 1159 |
* |
| 1160 |
* `whenClosing` (default true) |
| 1161 |
* Whether to autoclose when the '/' of a closing tag is typed. |
| 1162 |
* `whenOpening` (default true) |
| 1163 |
* Whether to autoclose the tag when the final '>' of an opening |
| 1164 |
* tag is typed. |
| 1165 |
* `dontCloseTags` (default is empty tags for HTML, none for XML) |
| 1166 |
* An array of tag names that should not be autoclosed. |
| 1167 |
* `indentTags` (default is block tags for HTML, none for XML) |
| 1168 |
* An array of tag names that should, when opened, cause a |
| 1169 |
* blank line to be added inside the tag, and the blank line and |
| 1170 |
* closing line to be indented. |
| 1171 |
* `emptyTags` (default is none) |
| 1172 |
* An array of XML tag names that should be autoclosed with '/>'. |
| 1173 |
* |
| 1174 |
* See demos/closetag.html for a usage example. |
