diff

问题 This StackOverflow answer has an image of KDiff3 highlighting intra-line differences. Does someone know of a tool which can show the same (ex, via color) on the command line? Another way to think of this is wanting to diff each difference in a patch file. 回答1: I don't know if this is sufficiently command line for your purpose, but vimdiff can do this (even does colour). See for example the image in this related question. 回答2: Another intuitive way to see all word-sized differences (though not

问题 How can I implement a diff function, such as Stack Overflow's question revision history? 回答1: You have here a javascript example of the implementation of a diff algorithm. Based on: P. Heckel, A technique for isolating differences between files Comm. ACM, 21, (4), 264--268 (1978). The implementation, itself, has two functions, one of which is recommended for use: diffString( String oldFile, String newFile ) This method takes two strings and calculates the differences in each. The final result

问题 I have a list of files in file.lst . Now I want to find all files in a directory dir which are older than 7 days, except those in the file.lst file. How can I either modify the find command or remove all entries in file.lst from the result? Example: file.lst : a b c Execute: find -mtime +7 -print > found.lst found.lst : a d e so what I expect is: d e 回答1: Pipe your find command through grep -Fxvf : find -mtime +7 -print | grep -Fxvf file.lst What the flags mean: -F, --fixed-strings Interpret

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . I have a patch file (unified diff), like the output from svn diff , git diff , or diff -u ... . I want to review it, but the unified diff format - especially with many files & changes - is hard on my eyes. How can I get a nicely-formatted diff view from the patch file? I don't have the files themselves, only the

问题 What is a good method for using diff to show a percentage difference between two files? Such as if a file has 100 lines and a copy has 15 lines that have been changed the diff-percent would be 15%. 回答1: Something like this perhaps? Two files, A1 and A2. $ sdiff -B -b -s A1 A2 | wc would give you how many lines differed. wc gives total, just divide. The -b and -B are to ignore blanks and blank lines, and -s says to suppress the common lines. 回答2: https://superuser.com/questions/347560/is-there

问题 Where can I find an explanation and implementation of the diff algorithm? First of all I have to recognize that I'm not sure if this is the correct name of the algorithm. For example, how does Stack Overflow mark the differences between two edits of the same question? PS: I know the C and PHP programming languages. 回答1: There is really no such thing as "the diff algorithm". There are many different diff algorithms, and in fact the particular diff algorithms used are in some cases considered a

问题 I'm using Intellij IDEA 14 on Windows and Git as VCS on Unix server. The line separator in Windows is CLRF ( \r\n ) and LF ( \n ) in Unix. In Git, I'm using config --global core.autocrlf input . This will translate all CRLF's to LF's upon commit. When I'm using "Reformat code" option on well-formatted file, IDEA marks files as changed and shows diff in line separators only. How can I disable that in IDEA? 回答1: In the bottom right of your window, change [CRLF] to [LF] 回答2: I'm also developing

问题 Is there any built-in, add-in solution for visual studio to compare two files and display result with differences? I could't find one... 回答1: I use WinMerge. Not as good as Beyond Compare but it's free and open source. Also check out Visual Studio Comparison Tools, it's a Visual Studio add-in that connects it to WinMerge. 回答2: Here is an excellent post that describes integration of many 3rd party diff and merge tools into Visual Studio - including araxis, beyond compare, WinMerge and many

问题 In this post I asked if there were any tools that compare the structure (not actual content) of 2 HTML pages. I ask because I receive HTML templates from our designers, and frequently miss minor formatting changes in my implementation. I then waste a few hours of designer time sifting through my pages to find my mistakes. The thread offered some good suggestions, but there was nothing that fit the bill. "Fine, then", thought I, "I'll just crank one out myself. I'm a halfway-decent developer,
