+ * This plugin can automatically format text patterns as you type. It includes several groups of patterns.
+ *
+ * Start of line patterns:
+ * As-you-type:
* - Unordered list (`* ` and `- `).
* - Ordered list (`1. ` and `1) `).
*
+ * On enter:
+ * - h2 (## ).
+ * - h3 (### ).
+ * - h4 (#### ).
+ * - h5 (##### ).
+ * - h6 (###### ).
+ * - blockquote (> ).
+ * - hr (---).
+ *
+ * Inline patterns:
+ * - <code> (`) (backtick).
+ *
* If the transformation in unwanted, the user can undo the change by pressing backspace,
* using the undo shortcut, or the undo button in the toolbar.
+ *
+ * Setting for the patterns can be overridden by plugins by using the `tiny_mce_before_init` PHP filter.
+ * The setting name is `wptextpattern` and the value is an object containing override arrays for each
+ * patterns group. There are three groups: "space", "enter", and "inline". Example (PHP):
+ *
+ * add_filter( 'tiny_mce_before_init', 'my_mce_init_wptextpattern' );
+ * function my_mce_init_wptextpattern( $init ) {
+ * $init['wptextpattern'] = wp_json_encode( array(
+ * 'inline' => array(
+ * array( 'delimiter' => '**', 'format' => 'bold' ),
+ * array( 'delimiter' => '__', 'format' => 'italic' ),
+ * ),
+ * ) );
+ *
+ * return $init;
+ * }
+ *
+ * Note that setting this will override the default text patterns. You will need to include them
+ * in your settings array if you want to keep them working.
