2/20/2023 0 Comments Merge a branch to master gitIn modern editors like VS Code, conflicts are automatically highlighted. To resolve the merge, we simply remove the markers and keep the changes we want to, whether that be from the receiving branch, or the target branch, or both, or a modification of them. The lines between > are from the target branch, here develop. This line is not affected by the conflict Thus, to do the merge, we first switch to the receiving branch (master) and run the merge command like so: But we have to switch to the receiving branch first before this command. Running git merge branch_name will merge branch_name onto the receiving branch. In our case, master can be thought of as the receiving branch, while develop can be thought of as the target branch. Here, we want to add the changes of develop onto master. Think of merging two branches as, adding the changes of one onto another. We will strictly be working with merging two branches, as that is sufficient for most use cases. Git’s answer is the aptly named git merge command, which can join two or more development histories or branches together. But, if our change was on tens of files and hundreds of lines of code, or more than a commit, that solution quickly falls apart. But that’s a painful recipe for disaster.īecause our change is so small, we could get away with this. ![]() Thinking about - switching to master, copying the new line and making a new commit might be tempting. How do we add the new change (commit) to master? Now assume that we got confirmation that the eggs can be added to the main grocery list i.e. This allows us to just keep track of the branch we’re on, and forget about the commit id - which is hard to remember. You can check that we’re on master by running:Īs we see, develop automatically moves to the new commit. To make commits that don’t affect our master branch, we need to make another branch (to no ones surprise). NOTE: I’m just making stuff up to minimize the dependencies to any particular language/runtime, hoping everyone can follow along. So, we don’t want to make any commits to master that we are unsure about. To mock the idea of a production environment, we’ll assume that the contents of our master branch are hosted on some website and are used by our family for buying groceries. Now let’s tackle problem 1 - adding a new feature. It’s is one of the reasons that makes Git efficient and blazing fast! This lightweight branch implementation is different, from that in other Version Control Systems (VCSs) - as opposed to copying the whole version histories for each branch. Because of this, a branch pointer in Git only has to point to a single commit, as its history can easily be traced by following its consecutive parent commits. How can you try out the idea for the new feature?Īs we can see, each commit points to its parent (previous) commit, except for the initial one. ![]() Therefore, if you’re sane, you won’t want to make any commits that could affect or break the stable production environment. Suppose your project calls for a new feature OR you just want to try out an experiment on the existing code.īut, assume your repository is also tied to a production environment. So if you think the title is crazy, read the full tutorial and judge for yourself.īut before we get into branching, it’s worth knowing what problems it solves for us. ![]() ![]() The idea of branching completely changes the way most people think about and write code. If you haven’t already read the previous tutorial on git basics, it is highly recommended you go through it before continuing with this one. If your answer is yes to any of the above, then this tutorial is something you must not miss.Įlse if your answer is no, then also keep reading, otherwise you risk missing out all the puns and the learns… Introduction Has the topic of Git Branches always confused you? Do you ever feel like you are not utilizing the full potential of Git?
