golang merge request

As the number of software developers continues to increase, source code management systems (SCM) are becoming increasingly important. Git is one of the most popular SCMs currently, with branching and merging capabilities, which makes team collaboration more convenient. In team collaboration, code review is a very important part, it helps to find errors and improve code quality. However, merging large amounts of code can be very time-consuming, especially in larger projects. To solve this problem, developers can use Git's merge request (Merge Request) function.

Merge requests are a feature in Git. Its main function is to encourage team collaboration, allowing other developers to check and review the code, and then merge the code into the main branch. Basically, a merge request sends a branch's changes to the Master branch so that other team members can review and discuss the changes and ultimately decide whether to merge the changes into the master branch.

In this article, we will introduce the use of merge requests in Golang, including the steps of creating a merge request, reviewing the code, and merging into the main branch.

Environment preparation

We need to install Git and Golang environments to run the examples in this article. Before starting, make sure you have installed them correctly.

Create a new branch

Before we start writing code, we need to create a new branch. Normally, to create a new branch, we can use the following command:

$ git checkout -b new-feature-branch

This will switch to a new branch and name it new-feature-branch. On this branch, you can develop and make changes, and then commit the changes to the Git repository.

Writing Code

Now, we use Golang to write a simple function that will return the sum of two integers. Let's call it the add function.

func add(x, y int) int {
    return x + y
}

Commit changes

After we finish writing the code, we need to push the changes to the branch. Commit all files into your local Git branch using the following command:

$ git add .
$ git commit -m "Add add function"

Create a merge request

Once we have finished developing the new feature, we need to merge the feature into the master branch. In order to merge changes into the master branch, we need to submit the changes in a merge request. Push your code to the new feature branch using the following command:

$ git push -u origin new-feature-branch

Now, switch to the new feature branch and you will see a link recommending a merge request action. Please click on the link and you will be directed to your Git repository website and presented with the Create Merge Request interface.

When creating a merge request, be sure to enter a description and details of your changes so reviewers can better understand your changes. After entering your merge request information, click the "Create Merge Request" button.

Review Code

Once a merge request is created, reviewers can review your changes and comment on them. Committers can get feedback by viewing all comments and issues on the merge request and make further developments based on reviewer feedback.

Reviewers can click the "File Changes" button on the merge request page to view the changed source files. Here they can comment, ask questions, and identify any potential issues.

Merge into master branch

Finally, we need to merge the changes into the master branch. Reviewers can click the Merge button to perform the merge operation. This operation will merge the changes and push them to the master branch. At this point, everyone on the team has access to the new functionality.

Summary

In this article, we introduced merge requests and how to use merge requests in Git. Using merge requests, team members can easily review and discuss other members' changes, which helps improve code quality and reduce errors. We also learned how to create merge requests, review code, and merge changes into the master branch.

Using merge requests in Golang is convenient and fast, and brings good results to team collaboration. Whether you're a contributor to an open source project or a member of an internal team, merge requests will give you a transparent, easy way to manage and track changes.
