是否有java库来做基于单词的差异？ [英] Are there java libraries to do a word-based diff?

问题描述

我有两段文字。我想在它们之间做一个基于单词的差异（比如当unix实用程序 wdiff 那么）但输出中有更多信息（我的意思是，字符的位置添加了/ delited word starts）。

I have two pieces of text. I would like to make a word-based diff between them (like whe unix utility wdiff does) but with more information in the output (I mean, the character's posizion where the added/delited word starts).

我需要在Java中这样做，所以差异的简单输出（如 wdiff ）不适合我：我想操纵表示差异的对象。

I need to do this in Java, so a simple output of the differences (like wdiff) doesn't suite for me: I would like to manipulate objects representing differences.

推荐答案

差异，匹配，修补程序 - 以Java提供，并且可以使用演示 - 似乎做差异。

There's Diff,Match,Patch - available in Java, and a demo is avilable - it seems to do word differences.
