If the two file similarity is very high, then the context format diff, will show a lot of duplicate content, it is a waste of space. In 1990, GNU diff pioneered the "Merge format" diff, which combines the context of F1 and F2.It is used by adding U parameters (representing unified). $ diff-u F1 F2 The res

SVN diff Replacement tool One. Replace SVN diff with Vimdiff: For most Linux developers, Vimdiff's presentation of file differences is obviously much more intuitive than SVN diff. So can we use Vimdiff instead of SVN diff? Fortunately, SVN considered this and supported Third-party programs as contrast differences. No

In fact, it's not just that the vue,react is also required to add the key to each component when performing a list rendering.To explain the role of key, we have to first introduce the Virtual Dom diff algorithm.We know that Vue and react both implement a set of virtual DOM, so that we can render the page without manipulating the DOM elements and simply manipulating the data. And the principle behind it is its efficient

Using Git in Windows, msysgit is the first choice, but the shell of msysgit is not powerful, the size cannot be changed, and the font is ugly. Therefore, in Windows, using Git in Cygwin is a good choice. Before submitting the code, or merging the code to view the code modification, we often need to diff to see what changes are there, and the diff output is obscure. When there are too many changes, like tian

Usage of git diffThere are three major parts of the Git commit: Working tree, index file, commitof these three parts: Working tree:Is the directory you work in, and whenever you make changes in your code, the state of the working tree changes.Index file: is a working tree and commit bridge, and whenever we use the Git-add command to register, the content of the index file changes, and the index file is synchronized with the working tree.Commit: It's the last stage, only commit, and our code real

react拥有极速渲染的特点，这个特点依靠的就是react的虚拟dom和diff算法对比两个图就可以发现标准dom机制下，用户在应用上的操作是直接对真实dom进行操作的，在react中我们操作的是虚拟dom，用户的操作产生的数据改变或者state变量改变，都会保存到虚拟dom上，之后再批量的对这些更改进行diff算法计算，对比操作前后的虚拟dom树，把更改后的变化再同步到真实dom上虚拟DOM的原理：React会在内存中维护一个虚拟DOM树，对这个树进行读或写，实际上是对虚拟DOM进行。当数据变化时，React会自动更新虚拟DOM，然后将新的虚拟DOM和旧的虚拟DOM进行对比，找到变更的部分，得出一个diff，然后将diff放到一个

When using securecrt during development, there is no graphical interface, and it is very difficult to view SVN version differences, mainly due to lack of graphical comparison under Win. Today we found a method to replace with vimdiff, which is better than simply looking at diff. However, we cannot choose to accept the version in a different place like win, you have to get started with the trade-off. Create a file somewhere. If you do not have the pe

In LINUX, when diff compares files, an error occurs: Binaryfilesfile1txtandfile2txtdiffer. in LINUX, use the diff command to compare files: [html] difffile1txtfile2txt. if both files are text files, the comparison is normal, if an error occurs during diff file comparison in LINUX: Binary files file1.txt and file2.txt differ, use the
