diff

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. 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 business advantage of the particular diff tool. In general, many diff algorithms are based on the Longest

I want to use Tortoise SVN diff utility with TFS. I know how to configure user tools in TFS. What I need is installer for Tortoise SVN diff utility. I think I need to install full Tortoise SVN to get SVN diff tool, is there a standalone version of this tool available for download? I know various other diff tools are available like winMerge etc. but I am very much familiar with tortoise svn diff. The TSVN diff tools are available separately. See the download page , scroll down to "Tools". Or directly from here . Dan If you want to use Tortoise Merge with TFS. You need to install Tortoise SVN .

A description of what I'm going to accomplish: Input 2 (N is not essential) HTML documents. Standardize the HTML format Diff the two documents -- external styles are not important but anything inline to the document will be included. Determine delta at the HTML Block Element level. Expanding the last point: Imagine two pages of the same site that both share a sidebar with what was probably a common ancestor that has been copy/pasted. Each page has some minor changes to the sidebar. The diff will reveal these changes, then I can "walk up" the DOM to find the first common block element shared by

基于开源软件做二次开发是很常见的。这类开发常常遇到的问题是，当我们已经针对开源软件做了很多修改，与上游主干版本之间已经渐行渐远；此时上游主干有了更新，此时如何把上游的更新与我们自己的修改合并起来？ 假定上游主干版本为A，我们在A的基础上开发了A'；此时上游主干更新到B，现在我们要做的事情就是相应更新到B'。 一个做法是用diff工具生成A'与A的差异（patch），然后在B上面应用这个patch，期望得到B'。用数学的公式表示就是： B' = B + (A' - A) ···· (i, using diff & patch) 如果使用git做版本控制，以上的做法是可行的，但不是最优的。更好的做法是 以A为基础，生成A'和B两条分支，然后执行 git checkout B; git merge A' 。有一种误解认为这个merge操作执行的就是上面的公式(i)，其实不然，git merge的算法叫做3-way merge（准确的说叫recusive 3-way merge，当两个分支有多个共同父亲时它比普通3-way merge表现得更好），用公式表示如下： B' = merge(A, A', B) ···· (ii, using 3-way merge) (ii) 比 (i) 好在哪里？ 用diff工具生成patch时，我们所做的每一处修改，会连同它的“定位信息”（行号

After a merge failed with some conflicts I can list those with git diff , but git difftool won't display them with the difftool set in the config(in my case Kaleidoscope), instead it will just use normal diff. A git difftool comparing with a previous commit will work. Is there a way to use git difftool on merge conflicts? Greets Jan Try git mergetool . Firstly try: git difftool -t <yourtool> If that doesn't work, look at man git-difftool and check the list of supported tools. Check if one of those does what you want, if it does then you've narrowed it down to git not supporting Kaleidoscope,

Using Visual Studio 2008 tools, I am trying to get an ASCII diff of change sets 14318 and 14317. I can do so using GUI: tf changeset 14318 and then select a file and right-click and select compare with previous version. However, this is a bit tedious and it is GUI-based. My task at hand is to back-port many changes into a different branch. I would like to automate the testing (say using Python), making sure that I did it correctly. Well, for educational purposes I will make all changes by hand without looking at the solution, and then I will compare the two changes and try to look for any

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, right?". Well, once I started to think about it, I couldn't quite figure out how to go about it. I can

Is there a command to do the opposite of diff? I want to compare two files if the same thing exists in both create a list of them. i am trying to figure out what entry's exist in both files. Here is a solution that WILL NOT change the order of the lines: fgrep -x -f file1 file2 Use the join command: join a.txt b.txt assuming the files are sorted; if not: sort a.txt > sorted_a.txt; sort b.txt > sorted_b.txt; join sorted_a.txt sorted_b

How can you perform a recursive diff of the files in two directories (a and b): $ diff -r a b but only look at files whose name matches a given pattern. For example, using the same syntax available in the find command, this would look like: $ diff -r a b -name "*crazy*" which would show diffs between files with the same name and path in a and b, which have "crazy" in their name. Effectively, I'm looking for the opposite of the --exclude option which is available in diff. Perhaps this is a bit indirect, but it ought to work. You can use find to get a list of files that don't match the pattern,
