实现DedeCms 5.7代码高亮功能的详细教程：一步步教你操作

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<table>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('<table ><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：

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：

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：

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( '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("
"); 
} 
}); 
// 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'] 
}); 
})(); 
[/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['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。

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/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。
