Breadcrumb Block
This is a single-block plugin for the breadcrumb trail. It’s simple, lightweight, SEO-friendly, and WooCommerce compatibility. It also includes some simple separator icons. It works everywhere: Page Editor, Site Editor, and template files. How to customize the breadcrumb How to change/remove an item? add_filter( 'breadcrumb_block_get_item', function ( $item_args, $context, $breadcrumbs_instance ) { // Ignore items without context. if ( ! $context || ! ( $context['object'] ?? false ) ) { return $item_args; } // Eg: remove a term. if ( 'term' === ( $context['type'] ?? '' ) && 'term-slug' === $context['object']->slug ) { return false; } // Eg: Change the title of a page. if ( 'page' === ( $context['type'] ?? '' ) && page_id_to_change === $context['object']->ID ) { $item_args[0] = 'Make it shorter'; } return $item_args; }, 10, 3 ); $item_args is a 3-item array: [$item_label, $item_link, $item_attrs] $context is an associative array: ['type' => 'item type', 'object' => 'item object']. type can be one of the following values: front_page, home, shop, page, post, single, term, taxonomy, post_type_archive, search, 404, paged, author, date_year, date_month, date_day, attachment. How to change the markup of the block? add_filter( 'breadcrumb_block_get_breadcrumb_trail', function ( $markup, $args, $breadcrumbs_instance ) { return $markup; }, 10, 3 ); How to add or remove the items from the breadcrumb trail? add_filter( 'breadcrumb_block_get_items', function ( $items, $breadcrumbs_instance ) { return $items; }, 10, 2 ); How to use a custom separator for the breadcrumb trail? add_filter( 'breadcrumb_block_get_args', function ( $args ) { // For example, change separator. $args['separator'] = ' '; return $args; } ); The custom separator should be an inline SVG. To make sure it displays properly, it should have three attributes: width, height, and fill. The values of these attributes should be as follows: fill="currentColor" width="1em" height="1em". Using this hook, you can customize other attributes such as container, before, after, list_tag, item_tag, item_before, item_after, separator. How to prepend the blog page to all single posts? add_action( 'breadcrumb_block_single_prepend', function ( $post, $breadcrumbs_instance ) { if ( 'post' === $post->post_type ) { $blog_id = get_option( 'page_for_posts'); if ( $blog_id ) { $breadcrumbs_instance->add_item( get_the_title( $blog_id ), get_permalink( $blog_id ) ); } } }, 10, 2 ); If this plugin is useful for you, please do a quick review and rate it on WordPress.org to help us spread the word.

Syntax-highlighting Code Block (with Server-side Rendering)
This plugin extends the Code block in WordPress core to add syntax highlighting which is rendered on the server. Pre-existing Code blocks on a site are automatically extended to include syntax highlighting. Doing server-side syntax highlighting eliminates the need to enqueue any JavaScript on the frontend (e.g. Highlight.js or Prism.js) and this ensures there is no flash of unhighlighted code (FOUC?). Reducing script on the frontend improves frontend performance, and it also allows for the syntax highlighted code to appear properly in AMP pages as rendered by the official AMP plugin (see also ampproject/amp-wp#972) or when JavaScript is turned off in the browser. This extended Code block uses language auto-detection to add syntax highlighting, but you can override the language in the block’s settings sidebar. (There is currently no syntax highlighting of the Code block in the editor, but see #8.) The plugin supports all programming languages that highlight.php supports (being a port of highlight.js). The Code block also is extended to support specifying lines to highlight which get marked up with mark elements (including in RSS feeds). There is also a checkbox for whether to show line numbers on the frontend (with the numbers being non-selectable). Lastly, given inconsistencies across themes regarding whether lines in a Code block should be wrapped, this plugin adds styling to force them to no-wrap by default, with a checkbox to opt in to wrapping when desired. For advanced usage, please see the plugin wiki. This plugin is developed on GitHub. See list of current issues with the plugin.
