You set up p4merge as your primary mergetool and you are able to use it for any conflict resolution. Thank you for reading! Did you like the article? Send me a comment.Git difftool will tell you what it's going to try. This message is displayed because 'diff.tool' is not configured. 'git difftool' will now attempt to use one of the following tools: See 'git difftool -tool-help' or 'git help config' for more details. guess_merge_tool () tool' will now attempt to use one of the following tools: We can find the process in the guess_merge_tool function. Is_available "$tool" & echo "$tool" & return 0 # Loop over each candidate and stop when a valid merge tool is found. List_merge_tool_candidates sets up the list of $tools. It assumes that if DISPLAY is not set you do not have a GUI which is incorrect on MacOS. Then it simply loops through them and picks the first one it finds an executable for using type. I've met some weird diff result when I execute git diff(I suspect BOM handling issue). I'd like to question the vendor(e.g., p4merge) about it,īut not sure if it is p4merge, vimdiff or anything else. If you're having an issue with git diff that is with git diff not git difftool. I think there's some confusion about what git difftool does, so here's a quick overview. git difftool does not pick the diff tool for git diff. git diff has its own internal diff implementation. It can also use an external diff program, like GNU diff, by supplying -ext-diff. When you run git difftool it picks an external diff program and runs it with three environment variables: $LOCAL, $REMOTE, and $MERGED. $LOCAL is a path to the old version of the file, $REMOTE to the new, and $MERGED to the name of the file so it can be displayed. We can see what git difftool does by adding to custom difftools to. gitconfig: Ĭmd = echo "LOCAL: $LOCAL, REMOTE: $REMOTE, MERGED: $MERGED" Git difftool -t echo will show the environment variables. git difftool -t less will look at the contents of the old and new versions of the files in the less pager. Git: How can I configure KDiff3 as a merge tool and diff tool? If you're having a problem with git diff, git difftool has nothing to do with it. These sites were very helpful, almost, mergetool and difftool. Hope this helps.Git config -global "C:/Program Files/KDiff3/bin/kdiff3.exe" You just need to execute the following commands: git config -global merge.tool kdiff3 I used the global configuration, but can be used by repository without problems. So if the above description doesn't work for you chances the problem lies somewhere else. However I tried creating an empty repo somewhere on my drive with git init, add a file, commit it, then modify it, then I tried difftool and it worked. I'm not sure what was the problem in that repo. Note: I had a repository in which even if I did issue the git difftool or git mergetool commands P4Merge wouldn't start. Then just use git difftool or git mergetool to your hearts content. So remove other stuff like difftool.path and all that. If p4merge is in this list then you just need to add the path where p4merge.exe resides to your %PATH% (on Windows I recommend Rapid Environment Editor for this).Īfter this is done you just need the following config to be in your. It'll list the available tools Git can use (because they've found them in your %PATH%) and the tools it could use (if they were installed). You can tell if this is the case or not by running git difftool -tool-help. Not sure if helps, but recent versions of Git support P4Merge (I use git version 2.17.0. When type of conflict is removed file conflict, git difftool command opens p4merge. I tried Smooth Git + P4merge but it does not work for me also I tried to do as described in External Merge and Diff Tools but I did not understand that. But when I use git difftool command in git bash, I expect p4merge but I see internal implementation of diff in git bash. =C:/Program Files/Perforce/p4merge.exeĭ=C:/Program Files/Perforce/p4merge.exe Git config -global "C:/Program Files/Perforce/p4merge.exe"Īnd these lines are from git config: merge.tool=p4merge Git config -global "C:/Program Files/Perforce/p4merge.exe" I follow this article and this one to setup and config p4merge: git config -global merge.tool p4merge I want to use p4merge as Git diff/merge tool.
