Python difflib gnu 补丁兼容性
可以使用与 GNU 补丁兼容的 python 模块 difflib 创建补丁吗？ 我尝试使用 Unified_diff 和 context_diff 并尝试将 lineterm 指定为“\n”，但我仍然收到此错误：
[intense@Singularity Desktop]$ patch diff.patch test.txt
patch unexpectedly ends in middle of line
patch: **** Only garbage was found in the patch input.
我使用 file.writelines(diff) 将补丁写入文件（代码段 http://pastebin.com/3HAWfwVf)
文件 test.txt:
Hello, this is test
blah
文件 test2.txt:
Hello, this is test
blah, dfsgjdfgj
lfkdjgkldfjgkldfjgkl
并生成补丁：

感谢您的帮助。
It's possible to create patch with python module difflib which is compatible with GNU patch?
I tried to use unified_diff and context_diff and also tried to specify lineterm as "\n" but I'm still gettings this error:
[intense@Singularity Desktop]$ patch diff.patch test.txt
patch unexpectedly ends in middle of line
patch: **** Only garbage was found in the patch input.
I used file.writelines(diff) to write patch into file (Piece of code http://pastebin.com/3HAWfwVf)
File test.txt:
Hello, this is test
blah
File test2.txt:
Hello, this is test
blah, dfsgjdfgj
lfkdjgkldfjgkldfjgkl
And generated patch:

我会使用mercurials bdiff 模块，它比difflib 快得多。
I'd use mercurials bdiff module, which is considerably faster than difflib.
diff -rNau dir-v1/ dir-v2/ > 1-2.patchinstead of difflib.
