EnlighterJS

EnlighterJS is a free, easy-to-use, syntax highlighting class developed for MooTools. It is based on the famous Lighter.js. Using it can be as simple as adding a single script and style to your website, choosing the elements you wish to highlight, and EnlighterJS takes care of the rest. It also supports Inline-Syntax-Highlighting as well as the automatic creation of tab-panes to display groups of code together (useful for multi-language examples - e.g. html+css+js) Take a look into the Documentation or view the Theme Demo

How to use

This is a minimalistic example how to highlight sourcecode with EnlighterJS. The working example (correct js+css paths) is available within the EnlighterJS package (Example1.html).

#HTML
<head>
...
<!-- Include EnlighterJS Styles -->
<link rel="stylesheet" type="text/css" href="EnlighterJS.yui.css" />

<!-- Include MooTools Framework -->
<script type="text/javascript" src="mootools-core-1.5.0-full-nocompat.js"></script>

<!-- Include EnlighterJS -->
<script type="text/javascript" src="EnlighterJS.yui.js" ></script>

<!-- Initialize EnlighterJS -->	
<meta name="EnlighterJS" content="Advanced javascript based syntax highlighting" data-indent="4" data-selector-block="pre" data-selector-inline="code.special" />
...
</head>
<body>
...
<!-- This code will be highlighted as Javascript !-->
<pre data-enlighter-language="js">
$('#loading-example-btn').click(function () {
  var btn = $(this)
  btn.button('loading')
  $.ajax(...).always(function () {
    btn.button('reset')
  });
});
</pre>
...
<p>Lorem ipsum dolor sit amet, consetetur sadipscing elitr, <code class="special">window.addEvent('domready', function(){});</code> labore et dolore magna aliquyam erat.</p>
</body>

Basic Usage

Download EnlighterJS and extract the files. Copy the prebuild files of the Build/ directory into a web-accessible directory of your choice.

Link to the EnlighterJS.yui.js javascript file and the EnlighterJS.yui.css stylesheet in the head section of your document after the MooTools file. The example below assumes you moved the files into your scripts folder under "js/" and your styles folder under "css/". The extension .yui indicates that these files are compressed with the Yahoo YUI Compressor. These files are ready for productive use! If you want to start developing, you should consider to use the uncompressed versions for easier debugging!

Rendering options can be defined as global option (Metainit attributes or options object) or local option using the data-enlighter- attributes on each codeblock. It is recommended to use local options only if necessary (e.g. to define a language for each block).

Integrate EnlighterJS

The integration of EnlighterJS requires the following 3 steps:

Integrate MooTools.Core, EnlighterJS Script+Styles into your page
Prepare your source code elements on your page by adding a language identifier
"Initialize" EnlighterJS to highlight the code

Link to the EnlighterJS.yui.js javascript file and the EnlighterJS.yui.css stylesheet

#HTML
<head>
...
<!-- Include EnlighterJS Styles -->
<link rel="stylesheet" type="text/css" href="css/EnlighterJS.yui.css" />
	 
<!-- Include MooTools Framework -->
<script type="text/javascript" src="js/mootools-core-1.5.0-full-nocompat.js"></script>

<!-- Include EnlighterJS -->
<script type="text/javascript" src="js/EnlighterJS.yui.js" ></script>
...
</head>

Prepare your source code by giving the element (containing the code) an optional data-enlighter-language attribute with the language of the code. Notice: Instead of Lighter.js *fuel:flame' syntax combo within the css classname, EnlighterJS will use HTML5 data- attributes!

#HTML
<!-- Syntax highlight using Javascript and default theme -->
<pre data-enlighter-language="js">var myClass = new Class({})</pre>

<!-- Syntax highlight using the Git Theme with default language-->
<pre data-enlighter-theme="git">php_info();</pre>

Finally, use the following JavaScript code examples inside of a 'domready' or 'onload' callback to create the highlighted elements - this process is called initialization. Be sure to check out the Options section to see the various options you can use. The Example pages have various examples you can use. Further informations as well as some advanced examples are available within the Initialization Section.

#JS
// Use the Init utility function to highlight all pre elements - this is the recommended way and required to use the Code-Group feature
EnlighterJS.Util.Init('pre', null, {
	language: 'php',
	theme: 'Classic'
});

Instead of initializing EnlighterJS manually, since version 1.1 it is possible to use a simple html-metatag (called EnlighterJS Metainit) to run Enlighter on your page (with basic config options).

#HTML
<!-- Initialize EnlighterJS -->	
<meta name="EnlighterJS" content="Advanced javascript based syntax highlighting" data-language="php" data-theme="Enlighter" data-indent="2" />

Some Examples

Since version 1.8, it's possible to highlight special lines of code. Just add the attribute data-enlighter-highlight to your codeblock and provide a set of lines to mark (ranges supported).

#HTML
<!-- just highlight line number 2 !-->
<pre data-enlighter-language="js" data-enlighter-highlight="2">
this.tokens = tokens || [];
options = this.options;
</pre>

<!-- highlight line 2,3,4 !-->
<pre data-enlighter-language="js" data-enlighter-highlight="2-4">
EnlighterJS.Util.Init('pre', null, {
   indent : 2,
   grouping: false
});
</pre>

Version 2.0 introduces some amazing features like Inline-Syntax-Highlighting. The Metainit tool performs this action automatically.

#JS
// Highlight all pre(block) + code(inline) tags and use Javascript as default language
EnlighterJS.Util.Init('pre', 'code', {
	language: 'javascript'
});

In some cases it might be usefull to start the linnumber counting with another value than 1 (maybe an excerpt). In this case you can add the data-enlighter-lineoffset attribute to your codeblock.

#HTML
<!-- start linenumber counting with line 15 !-->
<pre data-enlighter-language="js" data-enlighter-lineoffset="15">
this.tokens = tokens || [];
options = this.options;
</pre>

Initialization

Initialization means, that all elements (you wish to highlight) get selected and rendered by EnlighterJS. The original codeblock is set invisible and the rendered one is injected after. This task can be performed in two different ways:

1. Metainit Initialization

Instead of initializing EnlighterJS by javascript, it's possible to use a simple html-metatag (called EnlighterJS Metainit) to run Enlighter on your page (with basic config options). This will be usefull if you only need a basic setup. Take a look into the examples Examples/Testcase.Metainit.html to see how it is working! Basically Metainit takes the given html attribute options and converts them into a options object. These options will be passed to the Enlighter.Util.Helper() utility function - for inline elements (InlineRenderer) identified by data-selector-inline as well as block elements (BlockRenderer) by data-selector-block. This will take all the work for you by adding a single line to the head section to use all the amazing EnlighterJS features like Inline-Syntax-Highlighting or CodeGroups!

Example

Description: It enables block highlighting for all pre elements on the page as well as inline highlighting for all code elements. Javascript is set as default language used for highlighting. Each tab is replaced by four spaces to avoid rendering issues. Additionally the "raw code button" is enabled which allows the user to toggle between highlighted and unhighlighted code (e.g. to copy code).

#HTML
<!-- Initialize EnlighterJS -->	
<meta name="EnlighterJS" content="Advanced javascript based syntax highlighting" data-indent="4" data-selector-block="pre" data-selector-inline="code" data-rawcodebutton="true" data-language="javascript" />

Attributes

Following attributes are available (optional) and will be converted to the required options object to trigger EnlighterJS.Util.Helper. Take a look into the Metainit.js sources to see how it is working.

name (string) REQUIRED - This attribute identifies the metatag and has to be set to "EnlighterJS" (case sensitive)
data-language (string) - Sets the default language of every codeblock (inline+block) on the page - default: generic
data-theme (string) - Sets the default theme of every codeblock (inline+block) on the page - default: enlighter
data-indent (number) - Number of spaces to replace tabs with (-1 means no replacement) - default: -1
data-selector-block (string) - The CSS selector to match all codeblocks for block-highlighting. Use "NULL" to disable block highlighting - default: pre
data-selector-inline (string) - The CSS selector to match all codeblocks for inline-highlighting. Use "NULL" to disable inline highlighting - default: code
data-rawcodebutton (boolean) - Enables the optional "RAW Code Button" which will appear in ever codeblock (Block Renderer) to switch between highlighted and un-highlighted code - default: false
data-windowwbutton (boolean) - Enables the optional " Button" which
data-infobutton (boolean) - Enables the optional " Button" which
data-linenumbers (boolean) - Display line-numbers in code-blocks (ol/li list used as container) - default: true
data-hover (string) - Defines a css-classname which is added to each line. To enable build-in hover effects set it to "hoverEnabled" (default), null to disable it or to any custom class - default: "hoverEnabled"

2. Javacript based Initialization

EnlighterJS provides 4 ways to get manually initialized:

Use the native Element.enlight() method which will automatically creates an EnlighterJS instance of the selected single element
Create a new instance of EnlighterJS and provide the single element to highlight
To use Code-Groups you have to use EnlighterJS.Util.Helper utility function

Notice: You can pass any of the Global Options with each method. Every method will invoke the EnlighterJS constructor.

Option 1 - Init Utility Function (recommended)

Option 1 - Native Element extension

#JS
// get element by it's ID and activate highlighting using markdown as language
document.id('myCustomCode').enlight({
  language: 'ruby', 
  indent: 2
});

// disable highlighting
document.id('myCustomCode').enlight(false);

Option 2 - Use an EnlighterJS instance (OOP Style)

#JS
// create a new EnlighterJS instance
var myEnlighter = new EnlighterJS(document.id('myCustomCode'), {
  language: 'php',
  showLinenumbers: false
});

// enable highlighting
myEnlighter.enlight(true);

Option 3 - Use an EnlighterJS.Util.Helper utility function

#JS
// Highlight all code tags (inline code) and use Javascript as default language
EnlighterJS.Util.Helper(document.getElements('code'), {
	language: 'javascript',
	renderer: 'Inline'
});





// OPTION1 - Element style syntax - get element by it's ID
document.id('myJsCode').enlight(true);
	
// OPTION2 - Element style syntax - highlight all pre elements with the class *myPhp*
// an EnlighterJS instance is automatically created
document.getElements('pre.myPhp').enlight({language: php});

Options

Customize EnlighterJS` appearance by using the following configuration options. Try to start with one of the Example pages!

Global Options

The following options can be passed to the following methods to customize the rendering behaviour:

EnlighterJS(codeblockElement, options = {}, container = null) constructor
EnlighterJS.Util.Helper(elements, options = {}) utility function
EnlighterJS.Util.Init(blockSelector, inlineSelector, options= {}) utility function (recommended)

Option Keys

language - (string) The default language used if no data-enlighter-language attibutes are used - default: "generic"
theme - (string) The default theme used if no data-enlighter-theme attibutes are used - default: "enlighter"
indent - (integer) Number of spaces to replace tabs with (-1 means no replacement) - default: -1
hover - (string) Defines a css-classname which is added to each line. To enable build-in hover effects set it to "hoverEnabled" (default), null to disable it or to any custom class - default: "hoverEnabled"
oddClassname - (string) CSS-classname of all odd lines - default: "odd"
evenClassname - (string) CSS-classname of all even lines - default: "even"
showLinenumbers - (boolean) Display line-numbers in code-blocks (ol/li list used as container) - default: true
forceTheme - (boolean) Forces the renderer to use ignore attribute theme setting data-enlighter-theme - default: false
renderer - (string) Defines the renderer used to generate the output. Use Inline for Inline-Syntax-Highlighting or Block for standard highlighting - default: Block
rawButton - (boolean) Enables the optional "RAW Code Button" which will appear in ever codeblock (Block Renderer) to switch between highlighted and un-highlighted code - default: true
infoButton - (boolean) Enables the optional "Info Button" which provides a link to enlighterjs.andidittrich.de - default: true
windowButton - (boolean) Enables the optional "Window Button" which opens a new window with the unhighlighted "raw" code within - default: true
grouping - (boolean) Enables code-groups (only used by EnlighterJS.Util.Helper utility) - default: true
inlineContainerTag - (string) The html tag-name of the container (inline-syntax-highlighting only) where the generated code is wrapped into - default: "span"
ampersandCleanup - (boolean) Should the ampersand escape sequence &amp; automatically replaced by the ampersand sign during code cleanup ? Useful to resolve double escaped html code - default: true
rawcodeDoubleclick - (boolean) Toggle RAW/Highlighted code on doubleclick ? - default: false

Example

#JS
var options = {
	language : 'javascript',
	theme : 'Eclipse',
	indent : 2,
	forceTheme: false,
	rawButton: false,
	showLinenumbers: false,
	renderer: 'Inline'
};

// Initialize EnlighterJS - use inline-highlighting only
EnlighterJS.Util.Init(null, 'code', options);

Element Options

Some options need to be applied directly to the container elements which holds the code to highlight. These "local" options will override all global options which are set.

data-enlighter-language (string) - The language of the codeblock - overrides the global default setting | Block+Inline Content option
data-enlighter-theme (string) - The theme of the codeblock - overrides the global default setting | Block+Inline Content option
data-enlighter-group (string) - The identifier of the codegroup where the codeblock belongs to | Block Content option
data-enlighter-title (string) - The title/name of the tab | Block Content option
data-enlighter-linenumbers (boolean) - Show/Hide the linenumbers of a codeblock (Values: "true", "false") | Block Content option
data-enlighter-highlight (string) - A List of lines to point out, comma seperated (ranges are supported) e.g. "2,3,6-10" | Block Content option
data-enlighter-lineoffset (number) - Start value of line-numbering e.g. "5" to start with line 5 - attribute start of the ol tag is set | Block Content option

Example 1

#HTML
<pre data-enlighter-language="js" data-enlighter-linenumbers="false" data-enlighter-lineoffset="5">
...
</pre>

Example 2

#HTML
<p>
EnlighterJS also supports <code class="special" data-enlighter-language="js">alert('Inline Sourcecode highlighting');</code> (since version 2.0).
</p>

Code-Groups

This example shows how to use code-groups. You can define a new code-group by adding a data-enlighter-group attribute to your code tags you want to group. The value is used as an internal identifier and is not shown anywhere (e.g. use numerical identifiers). The name/title of the tab is defined by a data-enlighter-title attribute. To use a corporate style within all code-blocks grouped together, the theme definition of the first code-block defined in your document (the group leader) is used as theme of the complete group - other theme definitions will be ignored. if no theme is specified, the default theme (defined in the options) will be used, which is recommended.

Define a Code-Group

#HTML
<!-- the following 3 code-blocks will be grouped togehter - the theme will be "enlighter" (global theme definition of the group-leader) !-->
<pre data-enlighter-language="js" data-enlighter-group="group0001" data-enlighter-title="Javascript">
this.tokens = tokens || [];
options = this.options;
</pre>

<!-- Theme definition will be ignored !-->
<pre data-enlighter-language="java" data-enlighter-theme="panic" data-enlighter-group="group0001" data-enlighter-title="pure Java">
import javax.swing.JOptionPane;

public class OddEven {
/**
 * "input" is the number that the user gives to the computer
 */
private int input; // a whole number("int" means integer)
</pre>

<!-- Theme definition will be ignored !-->
<pre data-enlighter-language="php" data-enlighter-theme="twilight" data-enlighter-group="group0001" data-enlighter-title="PHP Script">
/** Test Snippet */
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
   
/* check connection */
if (mysqli_connect_errno()) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}
</pre>

Initialize Code-Groups

The initialization of code-groups differs from the standard. You have to use the EnlighterJS.Util.Helper utility function (triggered by Metainit and EnlighterJS.Util.Init) - it does the complete initialization and grouping for you!

JS-Initialization Chain: EnlighterJS.Util.Init -> EnlighterJS.Util.Helper -> EnlighterJS
Metainit-Initialization Chain: EnlighterJS.Util.Metainit -> EnlighterJS.Util.Helper -> EnlighterJS

Finally, use the following JavaScript code inside of a domready or onload event to create the highlighted elements. Check out the options section to see the various options you can use.

Notice: grouping has to set to true when using the javascript based initialization

#JS
// highlight all pre tags; no inline-highlighting
EnlighterJS.Util.Init('pre', null, {
    indent: 4,
    language: 'js',
    theme: 'enlighter',
    grouping: true,
    rawButton: true
});

Custom Builds

The EnlighterJS project is using Apache ANT as build-system. The YUI Compressor is used minify the production-ready javascript and css files. To save bandwith/traffic or include self-defined languages, you can easily customize your EnlighterJS build by editing the build.xml file (found in the root directory) and run Apache ANT Build (target build)

You can also use the webbased EnlighterJS Builder to generate your customized package without the need of ANT - everything is done for you serverside!

If you want to remove some of the default theme you can edit the include.themes property and modify the list of css source files. For Example: only include the Git and Mocha themes

#XML
<!-- Themes to include !-->
<property name="include.themes" value="Source/Themes/Git.css Source/Themes/Mocha.css" />

Or Include only your custom themes

#XML
<!-- Themes to include !-->
<property name="include.themes" value="Source/Themes/Custom1.css Source/Themes/Custom2.css" />

Removing/Adding languages is also easy as this - they are defined by the include.languages property. For Example: only include html+css+js syntax highlighting (be carefull - html is an alias for XML!, you have to include Xml.js)

#XML
<!-- Languages to include !-->
<property name="include.languages" value="Source/Languages/Css.js Source/Languages/Xml.js Source/Languages/Js.js" />
