diff

问题 I\'ve found git mergetool to be a handy utility for merging diffs visually, but the way I\'m going about it seems really wonky. Essentially, my process looks like this when conflicts are reported: Execute a git mergetool At the prompt, hit Enter to launch my diff tool (Meld or FileMerge, depending on which computer) Resolve the conflicts Save the changes Close the diff tool If I have more than one conflict, rinse, repeat. Yep, that\'s me opening and closing my diff viewer once for each

问题 I have a series of text files for which I\'d like to know the lines in common rather than the lines which are different between them. Command line unix or windows is fine. foo: linux-vdso.so.1 => (0x00007fffccffe000) libvlc.so.2 => /usr/lib/libvlc.so.2 (0x00007f0dc4b0b000) libvlccore.so.0 => /usr/lib/libvlccore.so.0 (0x00007f0dc483f000) libc.so.6 => /lib/libc.so.6 (0x00007f0dc44cd000) bar: libkdeui.so.5 => /usr/lib/libkdeui.so.5 (0x00007f716ae22000) libkio.so.5 => /usr/lib/libkio.so.5

问题 Is there a way to use Winmerge inside of git to do Diffs? 回答1: Update June 2015, 6 years later: As detailed in "git mergetool winmerge", a simple git config diff.tool winmerge will be enough. Git 2.5+ (Q2, 2015) is now aware of Winmerge as a diff or merge tool! Original answer (2009-2012) (msysgit, 1.6.5, DOS session) The first part (using winmerge) is described in "How do I view ‘git diff’ output with visual diff program?" C:\myGitRepo>git config --replace --global diff.tool winmerge C:

问题 Or just all the commits that occurred between two dates? In SVN, you could do something like svn diff -r{date}:{date} to do it! I can\'t seem to find a Git equivalent to this. Specifically I\'m looking at writing a script to send out daily emails with all the code committed that day and by who. 回答1: You could use git whatchanged --since="1 day ago" -p It also takes a --until argument. Docs 回答2: The previous suggestions have some drawbacks. Basically, I was looking for something equivalent to

问题 I\'m interested in seeing a good diff algorithm, possibly in Javascript, for rendering a side-by-side diff of two HTML pages. The idea would be that the diff would show the differences of the rendered HTML. To clarify, I want to be able to see the side-by-side diffs as rendered output. So if I delete a paragraph, the side by side view would know to space things correctly. @Josh exactly. Though maybe it would show the deleted text in red or something. The idea is that if I use a WYSIWYG editor

问题 How do I do a diff of two strings or arrays in Ruby? 回答1: diff.rb is what you want, which is available at http://users.cybercity.dk/~dsl8950/ruby/diff.html via internet archive: http://web.archive.org/web/20140421214841/http://users.cybercity.dk:80/~dsl8950/ruby/diff.html 回答2: For arrays, use the minus operator. For example: >> foo = [1, 2, 3] => [1, 2, 3] >> goo = [2, 3, 4] => [2, 3, 4] >> foo - goo => [1] Here the last line removes everything from foo that is also in goo, leaving just the

问题 How does the patience algorithm differ from the default git diff algorithm, and when would I want to use it? 回答1: You can read a post from Bram Cohen, the author of the patience diff algorithm, but I found this blog post to summarize the patience diff algorithm very well: Patience Diff, instead, focuses its energy on the low-frequency high-content lines which serve as markers or signatures of important content in the text. It is still an LCS-based diff at its core, but with an important

问题 How can I get the difference between two images? I have the original image. Someone has written on an exact duplicate of the original image. Now, I need to compare the original to the written on image and extract just the writing in image format. Example: I have a picture of a house. Someone took a copy and wrote “Hello!” on the copy. I want to somehow compare the two pictures, remove the house, and be left with an image of the words “Hello!”. Is this possible with ImageMagick? I know there

问题 The man page for git-diff is rather long, and explains many cases which don\'t seem to be necessary for a beginner. For example: git diff origin/master 回答1: Lets take a look at example advanced diff from git history (in commit 1088261f in git.git repository): diff --git a/builtin-http-fetch.c b/http-fetch.c similarity index 95% rename from builtin-http-fetch.c rename to http-fetch.c index f3e63d7..e8f44ba 100644 --- a/builtin-http-fetch.c +++ b/http-fetch.c @@ -1,8 +1,9 @@ #include "cache.h"
