JVM Gutenberg Rich Text Icons

Description

Add inline icons to rich text fields like: paragraphs, headings, lists or buttons anywhere in the Gutenberg block editor.

The icon set also creates a new field type for Advanced Custom Fields (ACF) : JVM Icon. This means you can create custom fields that work with a the font awsome icon set or even beter: A custom loaded icon set.

This plugin ships with the free Font Awesome 4.7 icon set as default icon set. I am aware this is not the most recent version but 4.7 is entirely free and works fine for my projects mostly. If you want to use some other icon set or a custom created icon set, keep reading.

The plugin simply inserts icons in the following HTML format:

<i class="icon fa fa-address-book" aria-hidden="true"> </i>

The CSS class names and available icons can be all be modified to your liking if you are prepared to write some PHP hooks for your WordPress theme.

CSS file
A slightly customized version of the Font Awesome 4.7 CSS file is loaded by default on the front end and backend to make the plugin work out of the box. If you want to use a custom icon set it is advised to overide the icon set json file and CSS file using hooks provided by this plugin.

Custom icon set file
By default the Font Awesome 4.7 icon set is loaded from: wp-content/plugins/jvm-richtext-insert-icons/src/icons.json. The json file contains all css classes that can be turned into icons by Font Awesome 4.7 CSS file. You can load a custom json icon set file by calling a filter hook in your (child) theme functions.php.
For example:

function add_my_icons($file) {
    $file = get_stylesheet_directory().'/path_to_my/icons.json';
    return $file;
}

add_filter( 'jvm_richtext_icons_iconset_file', 'add_my_icons');

The icon config file can also be in fontello format since version 1.0.3. Have a look at: https://fontello.com to create your customized icon set.

Custom CSS file
By default the Font Awesome 4.7 CSS is loaded from: wp-content/plugins/jvm-richtext-insert-icons/dist/fa-4.7/font-awesome.min.css. You can load a custom CSS file for your icon set by calling a filter hook in your (child) theme functions.php.
For example:

function add_my_css($cssfile) {
    $cssfile = get_stylesheet_directory_uri().'/path_to_my/cssfile.css';
    return $cssfile;
}

add_filter( 'jvm_richtext_icons_css_file', 'add_my_css');

If you choose the load your own CSS file and want to disable the default CSS file use the following code:

add_filter( 'jvm_richtext_icons_css_file', '__return_false');

All icon markup has the classname “icon” prefixed to the icon HTML inserted. If you want to use some other prefix you can add a filter. Like this:

function my_icon_class($css_class_name) {
    return 'my-custom-css-class-name';
}

add_filter( 'jvm_richtext_icons_base_class', 'my_icon_class');
