修改并上传SyntaxHighlighter源码个性化博客代码风格

或许是我太苛刻了，用了博客园默认的SyntaxHighlighter工具高亮代码后，总不尽人意。首先是行间距太大，这对于只贴小量的代码没什么问题。但如果代码很长，将会很大程度上影响阅读效率。其次，博客园似乎修改了SyntaxHighlighter原版代码不能自动换行的问题，但改得不彻底，又引出了新的问题：自动换行后会导致行号不连惯，并且产生多行注释时的Bug。

但也有改的好的地方，比如字体比原来默认的漂亮多了，高亮的颜色也更加符合阅读习惯，还有就是给代码的行加上了两种不同的背景色，交替显示，这都让代码看起来舒爽了很多。

最后，我还是决定自己动手，查找资料，上传并修改SyntaxHighlighter源码，基本上达到了预期的目标。

1.下载并修改SyntaxHighlighter源码

1.1下载SyntaxHighlighter

可到http://alexgorbatchev.com/SyntaxHighlighter/下载SyntaxHighlighter。我下的是8.0.83版本。

1.2 修改源码

找到styles/shCoreDefault.css文件，按照如下方式修改:

  /* font-weight: bold !important; */
  font-weight: normal !important;
}

这里并没有添加自动换行的功能，暂时先在写博客时手动调整一下单行代码的长度，别越界就OK了。

2.上传源码并在Blog中设置

2.1上传文件

需要上传两种类型的文件：

  • css文件，将刚刚修改好的shCoreDefault.css上传即可。
  • js文件，shCore.js是必传的，另外再可以有选择性的上传你需要的文件。比如我常用C++，偶尔用css，那么就可以只上传shBrushCpp.js和shBrushCss.js两个文件。当然，也可以全部js文件都传上去。

如图(我只上传了部分文件)：

6H91$YI74JO`C3BK_8C7K1N

2.2 设置Blog.

这一步的主要目的是在合适的位置添加合适的源码，使你刚刚上传的源码文件发挥作用。你需要在博客园-->设置-->子标题中添加如图所示代码：

0DU6FRS[_B[A38_V`HSX{)K

全部代码为：

<script type="text/javascript" 
src="https://files.cnblogs.com/chinaxmly/shCore.js"></script>
<script type="text/javascript" 
src="https://files.cnblogs.com/chinaxmly/shBrushCpp.js"></script>
<script type="text/javascript" 
src="https://files.cnblogs.com/chinaxmly/shBrushCss.js"></script>
<script type="text/javascript" 
src="https://files.cnblogs.com/chinaxmly/shBrushXml.js"></script>
<script type="text/javascript" 
src="https://files.cnblogs.com/chinaxmly/shBrushJScript.js"></script>
<link type="text/css" rel="stylesheet" 
href="https://files.cnblogs.com/chinaxmly/shCoreDefault.css"/>
<script type="text/javascript">
    SyntaxHighlighter.config.strings.help = "";
    SyntaxHighlighter.config.strings.expandSource = "+ 查看代码";
    SyntaxHighlighter.all();
</script>

说明：

  • herf和src的值为你的博客地址加文件名称。
  • “SyntaxHighlighter.config.strings.help = “”;”这句话用于去掉代码右上角的小‘？’号。

3. 个性化代码风格

将你的代码包含在如下的<pre></pre>标签中即可：

<pre class="brush: cpp; highlight: [12, 15]; first-line: 10; 
	html-script: false; light: false; auto-links: false; 
	collapse: true; class-name: 'class_name_demo';">
// 你的代码
</pre>

最终的效果如下所示（C++）：

// 程序初始化仿真

#define TRUE 1
#define FALSE 0

typedef char*			LPSTR;
typedef const char*		LPCSTR;

#include &lt;iostream&gt;

using namespace std;

///////////////////////////////////////////////////////////
// Window message map handling
struct AFX_MSGMAP_ENTRY;	// declared below after CWnd

struct AFX_MSGMAP
{
	AFX_MSGMAP* pBaseMessageMap;
	AFX_MSGMAP_ENTRY* lpEntries;
};

// DECLARE_MESSAGE_MAP
#define DECLARE_MESSAGE_MAP()													\
	static AFX_MSGMAP_ENTRY _messageEntries[];									\
	static AFX_MSGMAP		messageMap;											\
	virtual AFX_MSGMAP* GetMessageMap() const;

/* 多行代码示例 */
class CFrameWnd : public CWnd uuuuuuuuuuuuuuuuuuuuuyyyy
	yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy
	yyyiuojfosfejosifoefsfijsojuosfa;
	fslfjeosjfoaifjeojsosjfessfeoij
{
public:    
	CFrameWnd() { }
	~CFrameWnd() { }

	virtual BOOL Create();
	virtual BOOL PreCreateWindow();
};

/*  单行注释 */

/*
* 多行注释
*/

class CView : public CWnd
{
public:
	CView() { }
	~CView() { }
};

BOOL CWnd::CreateEx()
{
	int x = 7;
	x++;
	char* = "Hello World.";
	PreCreateWindow();
	// 系统函数
	ps1 = (char *)malloc(10);	// 在堆区分配10个字节
	ps2 = (char *)malloc(20);	// 在堆区分配20个字节

	return TRUE;
}
