Preserving whitespace with Pygments

I'm currently writing an application that uses Pygments to perform syntax highlighting. The problem I'm having is any code I process with Pygments has the leading and trailing whitespace in the file removed, and a single line break added to t开发者_开发技巧he end. Is there a way to make Pygments preserve the whitespace?

I think you want to make your own lexer, e.g.

lexer = lexers.get_lexer_by_name("python", stripnl=False)

and explicitly pass it to pygment.highlight. See the lexers' reference here.
