How to Automatically Resolve Git Merge Conflicts in Favor of Any Side?

As a developer, you probably love coding but dread the inevitable merge conflicts that come with Git. These conflicts can disrupt your flow and waste precious time. Fortunately, there's a way to automate the resolution process, ensuring you can keep working smoothly. In this article, I'll show you how to set up automatic conflict resolution in Git, favoring either your changes or those from another branch.

My First Encounter with Merge Conflicts

I remember my first major merge conflict like it was yesterday. I had just finished a big feature and was excited to merge my branch. Instead of celebrating, I spent hours manually resolving conflicts. It was frustrating, to say the least. That's when I realized there had to be a better way.

Understanding Merge Conflicts

Before we dive into the solution, let’s quickly recap what merge conflicts are. When two branches have changes to the same parts of the code, Git gets confused about which changes to keep, resulting in a merge conflict.

Why Automate Conflict Resolution?

If you've ever spent hours resolving conflicts manually, you know how painful it can be. Automating this process not only saves time but also reduces the risk of human error, ensuring your workflow remains efficient and stress-free.

Setting Up Automatic Conflict Resolution

Here's the good stuff—how to set up Git to automatically resolve conflicts in favor of one side. There are two common scenarios: resolving conflicts in favor of your changes (theirs) or the changes from the other branch (ours).

1. Resolve Conflicts in Favor of Your Changes

To automatically resolve conflicts in favor of your branch, use the following command:

git merge -X theirs <branch-name>

Replace <branch-name> with the name of the branch you are merging into your current branch. The '-X theirs' option tells Git to use the changes from your branch whenever there is a conflict.

2. Resolve Conflicts in Favor of the Other Branch

Conversely, if you want to prioritize the changes from the other branch, use:

git merge -X ours <branch-name>

This time, the '-X ours' option instructs Git to keep the changes from the branch you are merging into.

Making It a Default Behavior

If you find yourself always resolving conflicts in favor of one side, you can set this behavior as the default for your Git repository.

Open the .gitconfig file in your repository and add the following:

[merge] conflictstyle = merge default = <side>

Replace <side> with 'ours' or 'theirs' based on your preference.

A Word of Caution

While automatic conflict resolution can be a huge time-saver, it’s not always the best solution. Automatically resolving conflicts means you might miss important changes from the other branch. Always review the merged code to ensure no critical updates are overlooked.

Conclusion

Git merge conflicts don’t have to be a source of frustration. By automating the resolution process, you can streamline your workflow and focus on what matters most: writing great code. Whether you prioritize your changes or those from another branch, the key is understanding and using the commands wisely.

Remember, the goal is to work smarter, not harder. Happy coding!
