Highlight JS Lite (HLJSL)
HLJSL is a simple wrapper for the highlight.js library and is designed to be a drop-in solution with minimal or no configuration required. Out of the box HLJSL provides:
-
Automatic code highlighting for
<pre><code>blocks using a Web Worker for performance. -
Automatic line numbers for
<pre><code>blocks which can be disabled according to preference. -
Automatic
prepadding (left-padding) correction allowing you to indent<pre><code>blocks just like any other code in your source files; view this pages source for examples. - Copy code to clipboard button with built-in language (i18n) support.
- Light and dark theme support with the ability to easily build your own theme.
Usage
HLJS comes precompiled and can be added to your site by including the appropriate files from the dist folder to your site: Include the hljsl.min.css and hljsl.min.js files in the <head> of your pages. Do not add the hljs.min.js file (notice the lack of l after hljs) this will be loaded by the Web Worker when needed.
The precompiled version of HLJSL uses a modified version of the light and dark StackOverflow theme. If you would like to compile HLJSL with a different theme the process is fairly simple and is covered in the Compile With a Different Theme section below.
For greater control over HLJSL there are configuration options you can modify covered in the next section. See the public methods section if you would like to use HLJSL manually or in conjunction with your own application.
Configure
HLJSL is designed to require zero configuration but there two ways to modify the default settings for HLJSL. Using query strings at the end of the HLJSL's src url will allow you to modify some of the core settings but not all of them:
- autoLoad=false will disable auto loading (auto processing) of code blocks.
- lazyLoad=false will disable lazy loading (lazy processing) of code blocks.
- hideNumbers=true will disable showing the line numbers on processed blocks.
For example if you wanted full control of when HLJSL processes code blocks you would add code similar to the following in your head tag:
You can also use the css classes hide-numbers and show-numbers to overwrite the current settings for individual <pre><code> blocks:
A more advanced way that allows complete control over all of HLJSL's settings is to set a global configuration object before the <script> tag that loads HLJSL:
You may include or exclude any combination of these options. Any missing options from the global configuration object will use HLJSL's default for that option.
Examples
If you believe in the adage a picture is worth more than a thousand words then the examples below are for you! Most of the following examples were copied from highlightjs line numbers and is an entirely different project with no connection to HLJSL or Caboodle Tech. If you are looking to just add line numbers to your existing installation of highlight.js you probably want that project instead.
The following demos are processed with HLJSL which is using a Web Worker to lazy process (lazy load) the code blocks as they are entering your screens view:

============
Author Name, <author@domain.foo>
you can write text http://example.com[with links], optionally
using an explicit link:http://example.com[link prefix].
* single quotes around a phrase place 'emphasis'
** alternatively, you can put underlines around a phrase to add _emphasis_
* astericks around a phrase make the text *bold*
* pluses around a phrase make it +monospaced+
* `smart' quotes using a leading backtick and trailing single quote
** use two of each for double ``smart'' quotes
- escape characters are supported
- you can escape a quote inside emphasized text like 'here\'s johnny!'

Given I have entered <input_1> into the calculator
And I have entered <input_2> into the calculator
When I press <button>
Then the result should be <output> on the screen
And I have a string like
