The problem: softwarerecs is useless because the experts are here, not there. Show 8 more comments. Active Oldest Votes. Also, being able to merge into a specific output file rather than edit the input files in place is invaluable for backing out of failed nerges. Meld isn't a real merge tool, it's a diff tool since it doesn't shows the base version view. Meld is horrible, especially for merges.
It has no option to "auto-transfer non-conflicting changes", making every merge horribly painful. Show 12 more comments. You can configure your own merge tool to be used with " git mergetool ".
Example: git config --global merge. Note that since p4merge is now one of the officially supported git mergetools, it shouldn't be necessary to muck with the tool. Make sure you're using correct quotation: stackoverflow. Add a comment. Wernight Wernight Perforce Merge is great. P4 is also used by Google. You can custom install only P4Merge without the rest of perforce.
The latest version of p4merge does not have the "read-only" interface. You can edit the merged file in the lower pane. This is a really great answer and discussion. Thank you for sharing!

Remember to try diffuse , too. I find that kdiff3 is terribly superior, solving most of the merge issue himself thanks a great matching with the common ancestor. Command line interface. Usable keyboard shortcuts. Nafeez Abrar 9 9 silver badges 26 26 bronze badges. Luke Luke 18k 24 24 gold badges 82 82 silver badges bronze badges. Kyralessa See stackoverflow. Thank you for introducing it to me!! I spend half hour trying to install meld. My main disappointement with that tool is its kind of 'read-only' interface.
You cannot edit manually the files and you cannot manually align. Git merge will automatically select a merge strategy unless explicitly specified. The git merge and git pull commands can be passed an -s strategy option. The -s option can be appended with the name of the desired merge strategy. If not explicitly specified, Git will select the most appropriate merge strategy based on the provided branches. The following is a list of the available merge strategies.
To set up your source control tool to use MATLAB as the application for diff and merge, you must first determine the full paths of the mlDiff , mlMerge , and mlAutoMerge executable files, and then follow the recommended steps for the source control tool you are using. P4Merge displays it better. Registration is optional and the software is free to use: "SourceGear DiffMerge is an award-winning file diff and merge tool that has been helping professional developers and hobbyists since SourceGear DiffMerge is licensed for use free of charge.
However, by registering DiffMerge you will help fund new product development, maintenance, and support. As a way of thanking our registered users and encouraging additional registrations, we have added some new features in 4.
In particular, I can remember a file in one folder, then compare the remembered file to another in a different folder. I find this useful maybe once or twice a month, where I don't have to move two files into the same folder to compare them eg SQL scripts not under source control. Show 4 more comments.

Agree, it's the best I've used. My observation: Its relatively slow when handling large files around 5MB. One of the few tools I was willing to pay good money to have for personal use. Everything else is cluttered, confusing, and pales in comparison pun intended.
After using Araxis for a long time my company has switched to KDiff3 for the following reasons: 1 When a merge in Araxis is cancelled the file still gets marked as resolved in TortoiseHg.
However we still use Araxis as our compare tool : — Michael Platings. As mentioned in the comments for other answers, a proper 3-way merge tool has 4 panels - base, local, remote and result. Araxis conflates base and result, which can lead to problems.
Add a comment. Kdiff3 conflict resolution algorithm is really impressive. The merged file is editable. Has slick keyboard shortcuts. See: An advanced feature is to use regular expressions for defining automatic merges.
I agree about the merge algorithm. It is incredible sophisticated, and strangely seems to "know" what you want to do in a way that other tools cannot. It regularly crushes diff3 and Subversion blarg , and can even be helpful with a Git merge. Big user of it, but I find myself seeing if there is a better alternative these days — chrispepper I've never found a 3 way merge app that's significantly better than KDiff3. P4Merge has a more modern interface, but when I tested it you couldn't edit the merged file I think you can do it now.
Mofi MrTelly MrTelly I don't know how to set it to support 3-way merging Can it display a base file in the middle, 2 changed files at left and right, so I can see what are changed in both files based on the base file and have the merged result of 2 changed files in at bottom? I'm using UltraCompare A bit of googling found this ultraedit. You'll get a screen looking like this: Note the word-difference higlighting.
As much as I love ediff, I see only two buffers above There does seem to be a 3-way merge in ediff called ediff-merge-with-ancestor but I'm not sure if it has 3 panes or 4, and also the screenshot above doesn't reflect that. Edited to show a three-way diff ShreevatsaR — unhammer.
If what's shown in the screenshot are the three things being merged, where is the output? You destructively modify one or more! That's why I mentioned that ab will copy the region from buffer a to buffer b.
I don't think there's a four-window version of ediff yet. It is an intuitive tool and has a graphical interface. You can make changes directly in the tool. Semantic Merge is different than many of its competitors. It has a parser that helps it resolve conflicts by reporting at the function level, rather than changes in position.
This makes refactoring a much easier proposition for developers. However, if the parser is not capable of determining the code, the tool will revert to a text-based merge tool of your choice. Free for open source projects. This is a higher-end product for comparing and merging.
It supports multiple programming languages with the ability to add more from online sources. Beyond Compare can read PDF files and other binary files for comparison, which most other tools do not support. Development teams with a decent development budget who needs the robust functionality found in this tool. Code Compare is a file and folder comparison and merge tool. It allows multi-directional merge and integrates well with Visual Studio. Code Compare is a Windows-only solution.
What is different about Meld is it allows users to compare files within different folders. You may not use this feature often. Meld is easy-to-use. The development team has not kept up-to-date with the software. It is not good for organizations requiring up-to-date software.
You have plenty of options when it comes to code merge tools. Many integrate well with tools you may already be using. The cost of these packages is not going to break any budgets, and in many cases, the solutions are open source with no costs.
Try different ones to see which will work best for your development environment. When you find a few tools that you like, consider using them alongside Retrace by Stackify.
