DedeCms 5.7实现代码高亮

无论建博客网站还是CMS类型网站，很多都需要代码高亮，国内比较优秀的CMS建站系统之一——织梦CMS，不像Wordpress一样又大把大把的插件可用，我用的是最新的dedeCMS 5.7，在网上搜了很长时间资料，大都写的是CKEditor和SyntaxHighlighter整合的文章，但是dedecms将ckeditor做了集成，和一般的只针对于ckeditor对config.js修改不同。所以只能自己琢磨修改了，现将方法写出供站长朋友们参考：

一、首先去SyntaxHighlighter官方网站下载，网址：http://alexgorbatchev.com/SyntaxHighlighter/download/，建议下载2.1版本，3.0版本的貌似不支持自动换行，这里使用的是2.1.382版本。将下载的文件解压在syntaxHighlight文件夹里，去除里面无用的文件，只留下scripts和styles文件夹。

二、新建dialogs文件夹，在里面新建一个名为syntaxhighlight.js的文件，内容如下：

因代码量过大,不宜贴出，请直接下载syntaxhighlight.js

如果想修改代码区域的样式请在以下代码处修改<table>标签里的样式。

onOk : function() {
							var i = this.getParentEditor();
							var h = i.getSelection();
							var g = h.getStartElement();
							var l = g && g.getAscendant("pre", true);
							var j = f();
							this.commitContent(j);
							var k = e(j);
							var m = CKEDITOR.dom.element
									.createFromHtml('<table style="border:1px solid #EAED9C;width:660px;"><tr><td><pre class="' + k + '">'
											+ c(j.code) +"</pre></td></tr><table>");
							if (l) {
								m.insertBefore(l);
								l.remove()
							} else {
								i.insertElement(m)
							}
						},

三、然后新建images文件夹，存放一个syntaxhighlight.gif图片文件，该图片文件在编辑器工具栏上显示，可以使用16*16像素的图片

四、新建lang文件夹，是语言包，里面有两个文件，一个是中文cn.js一个是英文en.js，代码内容如下：

en.js代码如下：

CKEDITOR.plugins.setLang('syntaxhighlight', 'en',
{
	syntaxhighlight:
	{
		title: 'Add or update a code snippet',
		sourceTab: 'Source code',
		langLbl: 'Select language',
		advancedTab: 'Advanced',
		hideGutter: 'Hide gutter',
		hideGutterLbl: 'Hide gutter & line numbers.',
		hideControls: 'Hide controls',
		hideControlsLbl: 'Hide code controls at the top of the code block.',
		collapse: 'Collapse',
		collapseLbl: 'Collapse the code block by default. (controls need to be turned on)',
		showColumns: 'Show columns',
		showColumnsLbl: 'Show row columns in the first line.',
		lineWrap: 'Disable line wrapping',
		lineWrapLbl: 'Switch off line wrapping.',
		lineCount: 'Default line count',
		highlight: 'Highlight lines',
		highlightLbl: 'Enter a comma seperated lines of lines you want to highlight, eg <em>3,10,15</em>.'
	}
});

cn.js代码如下：

CKEDITOR.plugins.setLang('syntaxhighlight', 'cn',
{
	syntaxhighlight:
	{
		title: '添加或更新代码',
		sourceTab: '代码',
		langLbl: '选择语言',
		advancedTab: '高级',
		hideGutter: '隐藏分割线',
		hideGutterLbl: '隐藏分割线和行号',
		hideControls: '隐藏工具栏',
		hideControlsLbl: '隐藏浮动工具栏',
		collapse: '代码折叠',
		collapseLbl: '默认折叠代码块 (需要启用工具栏)',
		lineWrap: '自动换行',
		lineWrapLbl: '关闭自动换行',
		autoLinks: '自动链接',
		autoLinksLbl: '不自动转换超链接',
		lineCount: '起始行号',
		highlight: '高亮行号',
		highlightLbl: '输入以逗号分隔的行号, 如 <em>3,10,15</em>.'
	}
});

五、新建plugin.js文件，该文件是ckeditor插件必须得文件，里面是对该插件的一些配置，代码如下：

CKEDITOR.plugins.add("syntaxhighlight", {
	requires : [ "dialog" ],
	lang : [ "cn" ],
	init : function(a) {
		var b = "syntaxhighlight";
		var c = a.addCommand(b, new CKEDITOR.dialogCommand(b));
		c.modes = {
			wysiwyg : 1,
			source : 1
		};
		c.canUndo = false;
		a.ui.addButton("Code", {
			label : a.lang.syntaxhighlight.title,
			command : b,
			icon : this.path + "images/syntaxhighlight.gif"
		});
		CKEDITOR.dialog.add(b, this.path + "dialogs/syntaxhighlight.js")
	}
});

六、由于dedecms 5.7自己集成了一个dedepage插件，用来添加ckeditor自定义插件，在/include/ckeditor/dedepage文件夹下，打开plugin.js文件在最后面添加：

requires : ['syntaxhighlight']，其中syntaxhighlight为代码高亮插件的文件夹名，添加完之后的代码如下：

// Register a plugin named "dedepage".
(function()
{
    CKEDITOR.plugins.add( 'dedepage',
    {
        init : function( editor )
        {
            // Register the command.
            editor.addCommand( 'dedepage',{
                exec : function( editor )
                {
                    // Create the element that represents a print break.
                    // alert('dedepageCmd!');
                    editor.insertHtml("#p#副标题#e#");
                }
            });
            // alert('dedepage!');
            // Register the toolbar button.
            editor.ui.addButton( 'MyPage',
            {
                label : '插入分页符',
                command : 'dedepage',
                icon: 'images/dedepage.gif'
            });

            // alert(editor.name);
        },
        requires : [ 'fakeobjects' ],
        requires : ['syntaxhighlight']
    });
})();

七，修改/include/ckeditor/ckeditor.inc.php文件，在$toolbar['Basic']数组的最后一行添加元素Code,修改后代码如下：

$toolbar['Basic'] = array(
            array( 'Source','-','Templates'),
            array( 'Cut','Copy','Paste','PasteText','PasteFromWord','-','Print'),
            array( 'Undo','Redo','-','Find','Replace','-','SelectAll','RemoveFormat'),
            array( 'ShowBlocks'),array('Image','Flash'),array('Maximize'),'/',
            array( 'Bold','Italic','Underline','Strike','-'),
            array( 'NumberedList','BulletedList','-','Outdent','Indent','Blockquote'),
            array( 'JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock'),
            array( 'Table','HorizontalRule','Smiley','SpecialChar'),
            array( 'Link','Unlink','Anchor'),'/',
            array( 'Styles','Format','Font','FontSize'),
            array( 'TextColor', 'BGColor', 'MyPage','Code')
        );

至此，编辑器的修改已经完成，修改后的syntaxhighlight文件夹文件目录结构图如下图：

将syntaxhighlight文件夹上传到/include/ckeditor/plugins/文件夹下，打开后台，添加文章试一下，看看编辑器的上最后一行是否出现了如图所示的按钮：

点击按钮弹出如下图所示的对话框输入代码，并且可以切换到高级选项对代码高亮显示做一些配置：

八，但是光这些还不够，还要在文章模板文件/templets/default/article_article.htm文件里引入高亮显示的笔刷JS文件和CSS文件，由于是需要引入很多JS，所以建议将引入的代码放在</body>标签之前，等待前面的网页加载完后加载，进行显示。

引入代码如下：

	<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shCore.js"> </script>
	<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushJava.js"></script>
	<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushJScript.js"></script>
	<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushPhp.js"></script>
	<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushScala.js"></script>
	<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushSql.js"></script>
	<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushVb.js"></script>
	<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushXml.js"></script>
	<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushBash.js"></script>
	<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushCpp.js"></script>
	<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushCSharp.js"></script>
	<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/cripts/shBrushCss.js"></script>
	<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushDelphi.js"></script>
	<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushDiff.js"></script>
	<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushGroovy.js"></script>

	<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushPlain.js"></script>
	<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushPython.js"></script>
	<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushRuby.js"></script>

	<link type="text/css" rel="stylesheet" href="/include/ckeditor/plugins/syntaxhighlight/styles/shCore.css"/>
	<link type="text/css" rel="stylesheet" href="/include/ckeditor/plugins/syntaxhighlight/styles/shThemeDefault.css"/>

	<script type="text/javascript">
		SyntaxHighlighter.config.clipboardSwf = '/include/ckeditor/plugins/syntaxhighlight/scripts/clipboard.swf';

		SyntaxHighlighter.all();
	</script>

当然，该整合也有点缺点，就是在html页面页面中可能会引入大量的JS文件，加载起来可能会比较慢，另外可拓展性不强，我也会不定期优化该插件，也希望各位网友能提出意见。
