$BASE - The common ancestor of the two files."destination" is the name we use internally, that's why the param is -d). $LOCAL - It's the file you're merging to (a.k.a."source" is the name we use internally, that's why the param is -s). $REMOTE - It's the file you're merging (also known as "theirs" or "source".Where $REMOTE, $LOCAL, $BASE and $MERGE are git params with the following meaning: Semanticmergetool.exe -s $REMOTE -d $LOCAL -b $BASE -r $MERGED To invoke SemanticMerge as a merge tool, we're using the following command line: gitconfig (except the part that I added for completeness):Ĭmd = C:/Users/pablo/AppData/Local/semanticmerge/semanticmergetool.exe -s \"$REMOTE\" -d \"$LOCAL\" -b \"$BASE\" -r \"$MERGED\" Git config -global mergetool.keepBackup false Git config -global mergetool.prompt false Git config -global "C:/Users/pablo/AppData/Local/semanticmerge/semanticmergetool.exe -d \"$LOCAL\" -s \"$REMOTE\" -b \"$BASE\" -r \"$MERGED\"" Git config -global merge.tool semanticmerge Check the Configuring external text diff and merge tools section for more information. You can configure SemanticMerge to use any external tool you want. Xmerge) to compare the bodies of elements and text blocks. Text diff: Using this configuration, SemanticMerge will use the included text based diff tool (called We enclose $REMOTE and $LOCAL (git params) in quotation marks to make sure the command is correctly invoked even if the paths contain spaces. Run the following command to get help about the available params: Whenever you run the semanticmergetool with only two params (left and right of the diff), it will work as a diff tool. Semanticmergetool.exe -s $LOCAL -d $REMOTE To invoke SemanticMerge as a diff tool, we're using the following command line: gitconfig file (except the part that I added for completeness):Ĭmd = C:/Users/pablo/AppData/Local/semanticmerge/semanticmergetool.exe -s \"$LOCAL\" -d \"$REMOTE\" Git config -global "C:/Users/pablo/AppData/Local/semanticmerge/semanticmergetool.exe -s \"$LOCAL\" -d \"$REMOTE\"" Git config -global diff.tool semanticdiff In order to configure SemanticMerge we will run the following commands: Configure diff: Configure it by using the git config commands.You set up p4merge as your primary mergetool and you are able to use it for any conflict resolution.Configuring SemanticMerge to be used as diff and merge tools for Git is rather simple. This article gave you a quick introduction to merging with git. git config -global mergetool.keepBackup false If you’d like to remove this file after merge automatically you have to disable mergetool backups. You can notice git created *.orig file with the content from both branches. Resolve the conflict and save the file.īranches were successfully saved. You can see that p4merge supports three-way merge. Merge couldn’t be performed automatically and manual resolution comes into place. C:\Users\Jakub\Desktop\ruby-sample > git merge iss1ĬONFLICT (add/add): Merge conflict in test.txtĪutomatic merge failed fix conflicts and then commit the result. I committed those changes and now I am trying to merge iss1 into master branch. The content of the file in master branch is master and the content in the iss1 branch is iss1. I created file called test.txt in both of them. Let’s resolve our first conflict that I created. Git config -global '\"C:/Program Files/Perforce/p4merge.exe\" $BASE $LOCAL $REMOTE $MERGED' It is a great tool with a lot of extra features and very good performance.įor setting up p4merge as your mergetool you have to run these commands. We will use p4merge as we already use it for a difftool. Let’s setup the tool and take a closer look at the basic usage. Mergetool is a command in git that lets you run your custom tool for resolving conflicts in your merged files. But even if you develop in trunk with more people, merging and the conflict resolution comes in place when two are working on the same file. If you use git you probably work with multiple branches. Merging is an important part of the development process. Today I am going to focus on the merging and conflict resolution with git merge and mergetool. Last time I wrote about git diff and difftool and showed you how to use them to compare different files and versions.
