使用 Python 渲染统一差异
我有一个包含 svn Unified diff 的字符串。我的 PyGTK 应用程序需要向用户显示此差异，并且我想像其他差异工具一样渲染它，或者至少将其着色。
您有什么建议吗，外部工具、库、自定义实现......？我正在查看 http://kafka.fr.free.fr/diff2html/ 但我更喜欢使用一些库或类似的东西，因此用户不需要安装第三方应用程序。
我想稍后将其用于 git 和 Mercurial diffs。
I have a string which contains svn unified diff. My PyGTK app need to show this diff to user, and I want to render it like other diff tools do, or at least have it colorized.
Do you have something to suggest, external tool, library, custom implementation...? I was loking at http://kafka.fr.free.fr/diff2html/ but I prefer to use some library or sth like that, so users don't need to install third party apps.
I want use this for git and mercurial diffs later as well.

您可以使用 difflib 生成差异，并 pygtkscintilla 用于语法高亮、行编号、代码折叠等。
如果您只想要语法高亮（而不是pygtkscintilla 提供的所有编辑器功能），那么您还可以查看 pygments。
You could use difflib to generate diffs, and pygtkscintilla for syntax-highlighting, line-numbering, code-folding, etc.
If you only want syntax-highlighting (as opposed to all the editor features offered by pygtkscintilla), then you could also look at pygments.
difflib.HtmlDiff类提供了执行此操作的工具。但是，HtmlDiff希望您传递完整的“之前”和“之后”文件，而不是从统一的 diff 文件开始。使用 svn/git/mercurial 命令可以轻松获取这些文件，而无需使用这些 VCS 的“diff”功能。The
difflib.HtmlDiffclass provides facilities for doing this. However, instead of starting with a unified diff file,HtmlDiffwants you to pass the complete "before" and "after" files. These files are easy to get with svn/git/mercurial commands without using the "diff" functionality of those VCS.GtkSourceView 是 pygtk 的 TextView 的替代品，它可以语法突出显示差异文件，包括统一差异。
GtkSourceView is a drop in replacement for pygtk's TextView that can syntax-highlight diff files, including unified diffs.
