How to implement checking and ignoring when an array/object path is moved when diffing arrays in JavaScript?

阅读更多关于 How to implement checking and ignoring when an array/object path is *moved* when diffing arrays in JavaScript?

问题 I have seen flitbit/diff but it says: Changes to arrays are recorded simplistically. We care most about the shape of the structure; therefore we don't take the time to determine if an object moved from one slot in the array to another.... So doesn't work there. How would you implement this? It seems very hard. Is it possible to build off one of these existing libraries to ignore array moves ? Or how would you implement it directly from scratch? My use case is, I want to keep track of all

Do you know any tool for Windows which can help? I know git-svn does something similar but I am not sure if it would work with a local copy

问题 Is there a way in R to compare objects and return something useful like where the differences are? I need to compare files, but am willing to read them in to data.frames. This might just be handled better from the command line, but I would like to encapsulate my testing into one R script. My next attempt will be to use ddply to send each line to a compare() function and return the line numbers of the "FALSE" lines, but that only works until you have one insertion or deletion, then everything

技巧：Vimdiff 使用转载地址： http://www.ibm.com/developerworks/cn/linux/l-vimdiff/ 各种 IDE 大行其道的同时，传统的命令行工具以其短小精悍，随手可得的特点仍有很大的生存空间，这篇短文介绍了一个文本比较和合并的小工具：vimdiff。希望能对在 Unix/Linux 系统上进行开发的朋友有所帮助。源程序文件（通常是纯文本文件）比较和合并工具一直是软件开发过程中比较重要的组成部分。现在市场上很多功能很强大的专用比较和合并工具，比如 BeyondCompare；很多IDE 或者软件配置管理系统，比如Eclipse, Rational ClearCase都提供了内建``的功能来支持文件的比较和合并。当远程工作在Unix/Linux平台上的时候，恐怕最简单而且到处存在的就是命令行工具，比如diff。可惜diff的功能有限，使用起来也不是很方便。作为命令行的比较工具，我们仍然希望能拥有简单明了的界面，可以使我们能够对比较结果一目了然；我们还希望能够在比较出来的多处差异之间快速定位，希望能够很容易的进行文件合并……。而Vim提供的diff模式，通常称作vimdiff，就是这样一个能满足所有这些需求，甚至能够提供更多的强力工具。在最近的工作中，因为需要做很多的文件比较和合并的工作，因此对Vimdiff的使用做了一个简单的总结
