Question

很想比较2个插图(第1版和第2版),以我个人能够转换为html的形式来理解差异,正如你可以认为,这里的某个职位是如何在“<>上编辑的。或如粗略地追踪修订之间的差别。

图书馆必须全面管理。

Answer 1

我有一个这样的班级图书馆,但我也把自己的工作推向下,以便你能够评估它是否适合你的内容。

Note that for everything I say below, if you think of each character as an element of a collection, you can implement the algorithm described below for any type of content. Be it characters of a string, lines of text, collections of ORM-objects.

整个算法围绕 ,是一次复读的办法。

首先,计算法试图在两种计算法之间找到LCS。这将是两个版本之间最长时间不变/相同的部分。然后算法认为这两个部分是“调整”。

例如,这里将如何调整两个实例说明:

      This long text has some text in the middle that will be found by LCS
This extra long text has some text in the middle that should be found by LCS
          ^-------- longest common substring --------^

然后,它可追溯适用于相关部分之前的部分以及其后的部分。

最终的“结果”可照此办理(用斜线表示其中一部分“没有”):

This ______long text has some text in the middle that ______will be found by LCS
This extra long text has some text in the middle that should____ be found by LCS

然后,作为休养办法的一部分,每一级休养电话将退回一批“行动”,根据是否有一个低血清反应系统,或其中任一部分缺失部分,这将产生以下结果:

If LCS, then it is a "copy" operation
If missing from first, then it is a "insert" operation
If missing from second, then it is a "delete" operation

So the above text would be:

Copy 5 characters (This)
Insert extra_ (apparently code-blocks here remove space, the underscore is a space)
Copy 43 characters (long text has some text in the middle that_)
Insert should
Delete 4 characters (will)
Copy 16 characters (_be found by LCS)

算法的核心非常简单,如果你想要的话,就应当能够执行。

我的班级图书馆有一些额外特征,特别是处理改动案文中的内容similar,以便你不要仅仅删除或插入业务,而且还要修改业务,如果你重新比较一些内容,如文本档案中的内容,这一点将非常重要。

班级图书馆可上网查询:DiffLib on IX/;你还将在Nuget上找到该图书馆,以便于在2010年视觉演播室安装。这份清单载于C#中,编号为3.5,并更新,因此,它将为NET3.5和4.0开展工作,而且由于这是双向释放(所有来源代码都在Gite Hub,但你可以从VB中加以使用)。 NET也是这样。

Answer 2

Google has something similar and it is available in C#, but have not looked at it any deeper. The demo looks pretty cool though.
