做了一个在线代码高亮的项目,强大的Python一如既往没让我失望,一个强大的Pygments模块可以对多种(很多)语言进行代码高亮

下面来介绍一下它:

首先安装很简单,使用easy_install来进行安装:

1	`easy_install pygments`

Copy after login

安装完后我们来使用,Python的简单不会让大家失望:

from pygments.lexers import PythonLexver
from pygments.formatters import HtmlFormatter
from pygments import highlight
 
formatter = HtmlFormatter(encoding='utf-8', style = 'emacs', linenos = True)
code = highlight('print "hello, world"', PythonLexer(), formatter)
 
print code

Copy after login

结果

1	`'<table` `class="highlighttable"><tr><td` `class="linenos"><div` `class="linenodiv"><pre` `class="brush:php;toolbar:false">1`

Copy after login

1	`<span` `class="k">print</span> <span` `class="s">"hello, world"</span>\n`

Copy after login

\n'

这样就简单的对代码进行了高亮,当然如果你做了上面操作,然后把内容输入到一个文件里查看,肯定大呼坑爹,因为根本没高亮,因为默认是不会输出css的我们还要获取css加入到html中去:

1	`css = formatter.get_style_defs()`

Copy after login

然后把css内容和上面的html一起写入到html文件就可以看到高亮的代码了(千万不要告诉我你不知道css应该放在什么位置)
