使用'diff'（或任何其他）获得文本文件之间的字符级别差异 [英] Using 'diff' (or anything else) to get character-level diff between text files

问题描述

我想使用'diff'来获得两行之间的差异和字符差异。
例如，考虑：

文件1

  abcde 
 abc 
 abcccd 
  

文件2

  abcde 
 ab 
 abccc 
  

使用 diff -u 我会得到：

  @@ -1,3 +1,3 @@ 
 abcde 
 -abc 
 -abcccd 
 \否在文件末尾有换行符
 + ab 
 + abccc 
 \文件末尾没有换行符
  

但是，它只显示我是这些行中的更改。我想看到的是：

  @@ -1,3 +1,3 @@ 
 abcde 
 -ab< ins> c< / ins> 
 -abccc< ins> d< / ins> 
 \文件末尾没有换行符
 + ab 
 + abccc 
 \文件末尾没有换行符
   
 
 
现在，我知道我可以使用 
 
 
 /code.google.com/p/google-diff-match-patch/rel =nofollow noreferrer>其他引擎来标记/检查特定行上的差异。 
解决方案
我没有检查python库，但最终找到了 Google 的解决方案足以满足我的需求。它实现在许多语言（其中的C＃）。我印象深刻。
 
I'd like to use 'diff' to get a both line difference between and character difference.
For example, consider:

File 1
abcde
abc
abcccd
File 2
abcde
ab
abccc
Using diff -u I get:
@@ -1,3 +1,3 @@
 abcde
-abc
-abcccd
\ No newline at end of file
+ab
+abccc
\ No newline at end of file
However, it only shows me that were changes in these lines. What I'd like to see is something like:
@@ -1,3 +1,3 @@
 abcde
-ab<ins>c</ins>
-abccc<ins>d</ins>
\ No newline at end of file
+ab
+abccc
\ No newline at end of file
You get my drift.

Now, I know I can use other engines to mark/check the difference on a specific line. But I'd rather use one tool that does all of it.
解决方案
I didn't check the python library but eventually found Google's solution good enough for what I needed. And it is implemented in so many languages (C# among them). I was impressed.
