码农即使做ppt，也离不开代码，在keynote下，如果要粘贴代码，如何做到语法高亮呢？

补充1，该功能由pygments提供支持，所以支持的语言见：http://pygments.org/languages/

补充2，下文中的直接转化剪贴板里的内容，设置语言为-S py，其中py的意思是如果这段代码存成文件的话，应该是.py，所以，如果你想要贴一段objective-c的代码，显然就是-s m了。

Do you want to display some code in a Keynote presentation?

It's easy. All you need is Homebrew installed.

First you need to install the program highlight.

$ brew install highlight

So you have a piece of code. For example some Python code. The take that snippet of code and save it to a file like code.py. Now all you need to do is run this:

$ highlight -O rtf code.py | pbcopy

Then, switch back into Keynote and simply paste.

But if you don't want to create a file of the snippet, simply copy the snippet from within your editor and run this:

$ pbpaste | highlight -S py -O rtf | pbcopy

The -S py means "syntax is py (for python)".

You can use highlight for a bunch of other things like creating HTML. See man highlight for more tips.
