DedeCms 5.7代码高亮怎么实现？

无论建博客网站还是CMS类型网站，很多都需要代码高亮，织梦CMS是国内比较优秀的CMS建站系统之一，不像Wordpress一样有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。

推荐学习：织梦cms

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，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

标签里的样式。

代码如下:

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(&#39;<table style="border:1px solid #EAED9C;width:660px;"><tr><td><pre class="&#39; + k + &#39;">&#39; 
+ c(j.code) +"

"); 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：

代码如下:

CKEDITOR.plugins.setLang(&#39;syntaxhighlight&#39;, &#39;en&#39;, 
{ 
syntaxhighlight: 
{ 
title: &#39;Add or update a code snippet&#39;, 
sourceTab: &#39;Source code&#39;, 
langLbl: &#39;Select language&#39;, 
advancedTab: &#39;Advanced&#39;, 
hideGutter: &#39;Hide gutter&#39;, 
hideGutterLbl: &#39;Hide gutter & line numbers.&#39;, 
hideControls: &#39;Hide controls&#39;, 
hideControlsLbl: &#39;Hide code controls at the top of the code block.&#39;, 
collapse: &#39;Collapse&#39;, 
collapseLbl: &#39;Collapse the code block by default. (controls need to be turned on)&#39;, 
showColumns: &#39;Show columns&#39;, 
showColumnsLbl: &#39;Show row columns in the first line.&#39;, 
lineWrap: &#39;Disable line wrapping&#39;, 
lineWrapLbl: &#39;Switch off line wrapping.&#39;, 
lineCount: &#39;Default line count&#39;, 
highlight: &#39;Highlight lines&#39;, 
highlightLbl: &#39;Enter a comma seperated lines of lines you want to highlight, eg <em>3,10,15</em>.&#39; 
} 
});

cn.js代码如下：

代码如下:

CKEDITOR.plugins.setLang(&#39;syntaxhighlight&#39;, &#39;cn&#39;, 
{ 
syntaxhighlight: 
{ 
title: &#39;添加或更新代码&#39;, 
sourceTab: &#39;代码&#39;, 
langLbl: &#39;选择语言&#39;, 
advancedTab: &#39;高级&#39;, 
hideGutter: &#39;隐藏分割线&#39;, 
hideGutterLbl: &#39;隐藏分割线和行号&#39;, 
hideControls: &#39;隐藏工具栏&#39;, 
hideControlsLbl: &#39;隐藏浮动工具栏&#39;, 
collapse: &#39;代码折叠&#39;, 
collapseLbl: &#39;默认折叠代码块 (需要启用工具栏)&#39;, 
lineWrap: &#39;自动换行&#39;, 
lineWrapLbl: &#39;关闭自动换行&#39;, 
autoLinks: &#39;自动链接&#39;, 
autoLinksLbl: &#39;不自动转换超链接&#39;, 
lineCount: &#39;起始行号&#39;, 
highlight: &#39;高亮行号&#39;, 
highlightLbl: &#39;输入以逗号分隔的行号, 如 <em>3,10,15</em>.&#39; 
} 
});

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：

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：

[code] 
// Register a plugin named "dedepage". 
(function() 
{ 
CKEDITOR.plugins.add( &#39;dedepage&#39;, 
{ 
init : function( editor ) 
{ 
// Register the command. 
editor.addCommand( &#39;dedepage&#39;,{ 
exec : function( editor ) 
{ 
// Create the element that represents a print break. 
// alert(&#39;dedepageCmd!&#39;); 
editor.insertHtml("
"); 
} 
}); 
// alert(&#39;dedepage!&#39;); 
// Register the toolbar button. 
editor.ui.addButton( &#39;MyPage&#39;, 
{ 
label : &#39;插入分页符&#39;, 
command : &#39;dedepage&#39;, 
icon: &#39;images/dedepage.gif&#39; 
}); 
// alert(editor.name); 
}, 
requires : [ &#39;fakeobjects&#39; ], 
requires : [&#39;syntaxhighlight&#39;] 
}); 
})(); 
[/code]

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：

代码如下:

$toolbar[&#39;Basic&#39;] = array( 
array( &#39;Source&#39;,&#39;-&#39;,&#39;Templates&#39;), 
array( &#39;Cut&#39;,&#39;Copy&#39;,&#39;Paste&#39;,&#39;PasteText&#39;,&#39;PasteFromWord&#39;,&#39;-&#39;,&#39;Print&#39;), 
array( &#39;Undo&#39;,&#39;Redo&#39;,&#39;-&#39;,&#39;Find&#39;,&#39;Replace&#39;,&#39;-&#39;,&#39;SelectAll&#39;,&#39;RemoveFormat&#39;), 
array( &#39;ShowBlocks&#39;),array(&#39;Image&#39;,&#39;Flash&#39;),array(&#39;Maximize&#39;),&#39;/&#39;, 
array( &#39;Bold&#39;,&#39;Italic&#39;,&#39;Underline&#39;,&#39;Strike&#39;,&#39;-&#39;), 
array( &#39;NumberedList&#39;,&#39;BulletedList&#39;,&#39;-&#39;,&#39;Outdent&#39;,&#39;Indent&#39;,&#39;Blockquote&#39;), 
array( &#39;JustifyLeft&#39;,&#39;JustifyCenter&#39;,&#39;JustifyRight&#39;,&#39;JustifyBlock&#39;), 
array( &#39;Table&#39;,&#39;HorizontalRule&#39;,&#39;Smiley&#39;,&#39;SpecialChar&#39;), 
array( &#39;Link&#39;,&#39;Unlink&#39;,&#39;Anchor&#39;),&#39;/&#39;, 
array( &#39;Styles&#39;,&#39;Format&#39;,&#39;Font&#39;,&#39;FontSize&#39;), 
array( &#39;TextColor&#39;, &#39;BGColor&#39;, &#39;MyPage&#39;,&#39;Code&#39;) 
);

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标签之前，等待前面的网页加载完后加载，进行显示。

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>

<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 = &#39;/include/ckeditor/plugins/syntaxhighlight/scripts/clipboard.swf&#39;; 
SyntaxHighlighter.all(); 
</script>

最后发表并生成的文章页面效果图如下：

　　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。
