version-control windows - What's the best visual merge tool for Git?
mergetool meld (16)
What's the best tool for viewing and editing a merge in Git? I'd like to get a 3-way merge view, with "mine", "theirs" and "ancestor" in separate panels, and a fourth "output" panel.
Also, instructions for invoking said tool would be great. (I still haven't figure out how to start kdiff3 in such a way that it doesn't give me an error.)
My OS is Ubuntu.
You can configure your own merge tool to be used with "
git config --global merge.tool p4merge git config --global mergetool.p4merge.cmd p4merge '$BASE $LOCAL $REMOTE $MERGED' git config --global mergetool.p4merge.trustExitCode false
And while you are at it, you can also set it up as your difftool for "
git config --global diff.tool p4merge git config --global difftool.p4merge.cmd p4merge '$LOCAL $REMOTE'
Note that in Unix/Linux you don't want the
$BASE to get parsed as a variable by your shell - it should actually appear in your ~/.gitconfig file for this to work.
I hear good things about kdiff3.
If you do use visual studio, Team Explorer built in tool is a very nice tool to resolve git merge conflicts.
Diffuse is my favourite but of course I am biased. :-) It is very easy to use:
$ diffuse "mine" "output" "theirs"
Diffuse is a small and simple text merge tool written in Python. With Diffuse, you can easily merge, edit, and review changes to your code. Diffuse is free software.
You can change the tool used by git mergetool by passing
git mergetool -t=<tool> or
--tool=<tool>. To change the default (from vimdiff) use
git config merge.tool <tool>.
I use different tools for merge and compare:
git config --global diff.tool diffuse git config --global merge.tool kdiff3
Fist could be called by:
git difftool [BRANCH] -- [FILE or DIR]
Second is called when you use
My favorite visual merge tool is SourceGear DiffMerge
- It is free.
- Cross-platform (Windows, OS X, and Linux).
- Clean visual UI
- All diff features you'd expect (Diff, Merge, Folder Diff).
- Command line interface.
- Usable keyboard shortcuts.
I've tried a lot of the tools mentioned here and none of them have quite been what I'm looking for.
Personally, I've found Atom to be a great tool for visualizing differences and conflict resolution/merging.
As for merging, there aren't three views but it's all combined into one with colored highlighting for each version. You can edit the code directly or there are buttons to use whichever version of that snippet you want.
I don't even use it as an editor or IDE anymore, just for working with git. Clean UI and very straight-forward, plus it's highly customizable.
You can start it from the command line and pass in a single file you want to open to, or add your project folder (git repo).
- I would also recommend project-manager as a very convenient way to navigate between projects without filling up your tree view.
The only problem I've had is refreshing -- when working with large repositories atom can be slow to update changes you make outside of it. I just always close it when I'm finished, and then reopen when I want to view my changes/commit again. You can also reload the window with ctrl+shift+f5, which only takes a second.
And it's free of course.
If you are just looking for a diff tool beyond compare is pretty nice: http://www.scootersoftware.com/moreinfo.php
Once you have have learned vim (and IMHO you should), vimdiff is just one more beautiful little orthogonal concept to learn. To get online help in vim:
If you're stuck in the dark ages of mouse usage, and the files you're merging aren't very large, I recommend meld.
You can install ECMerge diff/merge tool on your Linux, Mac or Windows. It is pre-configured in Git, so just using
git mergetool will do the job.
Beyond Compare 3, my favorite, has a merge functionality in the Pro edition. The good thing with its merge is that it let you see all 4 views: base, left, right, and merged result. It's somewhat less visual than P4V but way more than WinDiff. It integrates with many source control and works on Windows/Linux. It has many features like advanced rules, editions, manual alignment...
The Perforce Visual Client (P4V) is a free tool that provides one of the most explicit interface for merging (see some screenshots). Works on all major platforms. My main disappointement with that tool is its kind of "read-only" interface. You cannot edit manually the files and you cannot manually align.
PS: P4Merge is included in P4V. Perforce tries to make it a bit hard to get their tool without their client.
Meld is a newer free tool that I'd prefer to SourceGear Diff/Merge: Now it's also working on most platforms (Windows/Linux/Mac) with the distinct advantage of natively supporting some source control like Git. So you can have some history diff on all files much simpler. The merge view (see screenshot) has only 3 panes, just like SourceGear Diff/Merge. This makes merging somewhat harder in complex cases.
PS: If one tool one day supports 5 views merging, this would really be awesome, because if you cherry-pick commits in Git you really have not one base but two. Two base, two changes, and one resulting merge.
So for the git merge, you can try:
DiffMerge to visually compare and merge files on Windows, OS X and Linux.
Meld, is a visual diff and merge tool.
- KDiff3, a diff and merge program), which compares or merges 2 or 3 text input files/dirs.
opendiff(part of Xcode Tools on macOS), a command line utility which launches the FileMerge application from Terminal to graphically compare files or directories, including merging.
I summarized other answers. You can execute
git pull without errors:
git fetch --all git reset --hard origin/master git reset --hard HEAD git clean -f -d git pull
Warning: This script is very powerful, so you could lose your changes.
