Highlight Search Terms vs Syntax-highlighting Code Block (with Server-side Rendering)

Highlights search terms within WordPress generated search results, both on the search results page and on each linked post page itself. This plugin is light weight and has no options. It started as very simple fusion between How to Highlight Search Terms with jQuery – theme hack by Thaya Kareeson and Search Hilite by Ryan Boren. It has since evolved with many optimizations, HTML5 and other plugin compatibility. Since version 1.6 it no longer depends on the jQuery library. Features Click through highlights: Highlights not only on WP search results page but also one click deeper inside a post page Character and case insensitive (lenient) highlighting Caching (WP Super Cache) compatibility Search terms wrapped in double quotes now considered as single term Compatible with: Woocommerce Search Filter Pro BuddyPress bbPress What does it do? This low impact plugin finds all search terms on a search results page inside each post and highlights them with a ... tag. Note that N is a number starting with 0 for the first term used in the search phrase increasing 1 for each additional term used. Any part of a search phrase wrapped in quotes is considered as a single term. What does it NOT do? There are no CSS style rules set for highlighting. You are free to use any styling you wish but to make the highlights visible in browsers that do not support HTML5 like Internet Explorer 8 or older you absolutely need to define at least one rule. Modern HTML5 browsers will use their own highlighting style by default, which usually is a yellow marker style background. So what do I need to do? In most cases, it should just work. But you can do two things to ensure backward browser and theme compatibility: Define CSS rules: There are no configuration options and there is no predefined highlight styling. You are completely free to define any CSS styling rules in your themes main stylesheet (style.css) or the Custom CSS tab if the WordPress theme customizer. You can find basic instructions and CSS examples in the FAQ’s. Check your theme: In most up to date themes (including WP’s own default theme) post and page content is shown inside a div with class hentry. This means search terms found in post and page content will be highlighted but not similar terms that accidentally show in the page header, sidebar or footer. If your current theme does not use the hentry class (yet), this plugin will look for IDs content, main and finally wrapper but if none of those are found, it will not work for you out of the box. See the last of the FAQ’s for ways to make it work. Available hooks and filters hlst_query_vars – The array of WordPress query variables that the plugin will identify as a search query. Must return an array. Default: ['search_terms','bbp_search'] (WordPress abd bbPress search) hlst_input_get_args – An array of GET variables that the plugin will identify as a search query. Must return an array. Default: ['hilite'] (for click-through highlighting) hlst_selectors – The array of possible HTML DOM element identifiers that the script will try. The first viable identifier it finds elements of will be scanned for search terms to mark, the rest is ignored. So the order is important here! Start with the element closest to, but still containing all the post/page title, excerpt or content. hlst_events – The array of DOM event listeners that the inline script will watch for. Default: ['DOMContentLoaded','post-load'] (on Document Ready and for Jetpack Infinite Scroll and others). hlst_inline_script – The inline script that will be added to the plugin script file. Can be used to add to or alter the inline script. Must return a string. Known issues & development If your theme does not wrap the main content section of your pages in a div with class “hentry” or HTML5 article tags, this plugin might not work well for you out of the box. However, you can make it work. See the last of the FAQ’s for an explanation. Josh pointed out a conflict with the ShareThis buttons plugin. Since then, that plugin has been completely rewriten so please let me know if the problem still exists. Thanks! Please file bug reports and code contributions as pull requests on GitHub.

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. Please feel free to file any additional issues or requests that you may come across. Pull requests are welcome. See contributing information.
