FCKeditor 和 SyntaxHighlighter 代码高亮插件的整合方法，里面有下载，可以根据需要结合自己的fckeditor版本。

Introduction（简介）

This is a dialog-based plugin to handle formatting of source code for FCKeditor 2.5.x. It WON'T work with the new CKEditor (yet).（CKEditor 是FCKEditor 的升级版，不过，SyntaxHighlighter 还不能在 CKEditor 中实现代码高亮） It makes use of the SyntaxHighlighter 2.0.x javascript library available to download from Alex Gorbatchev's project page (the older version 1.5.1 version is available from Google Code).

The plugin primiarily edits a <pre> tag with some custom attributes. Its mainly aimed at users editing blogs or content management systems where there is a requirement to format programming languages on a website that is being edited using FCKEditor.

The plugin will not format the code in FCKEditor - the SyntaxHighlighter javascript library dynamically generates a lot of formatted HTML at runtime, which would cause problems in FCKEditor.

Skip straight to the good bits

Can't be bothered reading all this? View the online demo or download the plugin and go play with it yourself.

So what do I get then?

Correctly installed, the plugin is in the form of a tabbed dialogue box that looks like this:（插件安装好以后的效果）

v1.0 [30 Nov 2008]. First version.

Known bugs:

Occasionally the dialogue box does not pickup the <pre> element to be edited in Firefox. It only seems to happen when a user clicks inside the <pre> tag with the mouse but doesn't actually move or interact with the cursor.
Fixed in version 1.0.2 - Thanks to Sergey Gurevich

Installation（安装配置过程）

1. Copying the files（拷贝文件）

Extract the contents of the zip in your plugins directory, so it ends up like this:（基本的目录结构如下）

Note: Version 2 of the plugin must be extracted to a directory named 'syntaxhighlighter2'. The older plugin for the earlier version of the library must go in a folder named 'syntaxhighlighter'. The file fckplugin.js references this directory when the plugin initialises.（注意这里的命名）

2. Adding it to FCKeditor（将它添加到 FCKeditor）

Now add in your fckconfig.js or custom js configuration file the following line (remember its javascript we are dealing with so everything is case sensitive!):

1.FCKConfig.Plugins.Add( 'syntaxhighlight2', 'en') ;

3. Adding it to the toolbarset

Add the button 'SyntaxHighLight2' button to your toolbarset:

FCKConfig.ToolbarSets["Basic"] = [
['Bold','Italic','-','OrderedList','UnorderedList','-','Link','Unlink', '-','SyntaxHighLight2','-','About']
] ;

4. Configure the plugin

The plugin will work 'out of the box', but you can configure a default language using the SyntaxHighlight2LangDefault parameter:

1.FCKConfig.SyntaxHighlight2LangDefault = 'csharp' ;

The full list of languages and corresponding codes are:

- c++ - C++
- csharp - C#
- css - CSS
- delphi - Delphi
- java - Java
- jscript - Java Script
- php - PHP
- python - Python
- ruby - Ruby
- sql - SQL
- vb - VB.NET
- xhtml - XML/HTML

In FCKEditor <pre> blocks aren't really formatted by default. I suggest editing your fck_editorarea.css (or equivalant if you are using a custom CSS file) to something that highlights code blocks better. eg:

pre
{
    background-color: #fff;
    font-family: "Consolas" , "Courier New" ,Courier,mono,serif;
    font-size: 12px;
    color: blue;
    padding: 5px;
    border: 1px dashed blue;
}

Configuring SyntaxHighlighter.

You must have SyntaxHighlighter installed and working to display properly formatted code. FCKEditor does not need it, but for code to be properly formatted on your website you must have it configurated correctly. For SyntaxHighlighter2 Alex Gorbatchev's site has loads of excellent information (he wrote it after all!), for the old version 1.5.1 library, the project wiki here is a good resouce, or this blog post might also be useful.

5. Use it

Now clear your browser cache (this stage is important!) and reload the editor, the new button should be ready to use.

6. Future updates

There's some additional functionality I might add at a later date:

Preview tab using the SyntaxHighlighter library
More configuration options, eg, available languages, path to SyntaxHighlighter files
Dynamically adding a <pre> formatting style to the editor by default
