我会做的很棒
<define tag="myTag" options="3"> <h1> #1 </h1> <ul> <li> #2 <li> #3 </ul> </define>
然后使用它：
<myTag option="foo" option="bar" option="bean" />
我认为宏是
真的很大的优势.
也许显而易见,但C预处理器可以完成这项工作.
index._html
#define _em(a) <em> a </em>
#define _image(a,b) <img src="a" b/>
#define _list(a,b,c) <h1> a </h1> \
<ul> \
<li> b </li> \
<li> c </li> \
</ul>
<!-- ___________________________________________________ -->
<!doctype html>
<html>
#define _theTile The Bar Title
#include "head._html"
<body>
_list(foo,bar,bean)
This is really _em(great)
_image(media/cat.jpg,)
_image(media/dog.jpg,width="25%" height="10px")
</body>
</html>
是head._html
<head>
<Meta charset="utf-8"/>
<title> _theTile </title>
<!-- more stuff ... -->
</head>
然后,
cpp -P index._html > index.html
生产：
<!doctype html>
<html>
<head>
<Meta charset="utf-8"/>
<title> The Bar Title </title>
<!-- more stuff ... -->
</head>
<body>
<h1> foo </h1> <ul> <li> bar </li> <li> bean </li> </ul>
This is really <em> great </em>
<img src="media/cat.jpg" />
<img src="media/dog.jpg" width="25%" height="10px"/>
</body>
</html>
