/**
|
||||
* Text pattern plugin for TinyMCE
|
||||
*
|
||||
* @since 4.3.0
|
||||
*
|
||||
* 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.
