Or you can merge your branch back into the main version. When you are ready, you can commit changes to save your progress. You can create a copy of your source code, known as a branch, which you can then work on in parallel to the main version. Git stores your source code and its full development history locally in a repository. This strategy - using squash when merging - is often used when a Pull Request is closed.Git is a distributed, open-source version control system (VCS) that enables you to store code, track revision history, merge code changes, and revert to earlier code version when needed. It will appear as if the work for your feature had happened in just a single commit. In the end, this allows you to avoid the automatic commit that typically happens as a result of a merge. The effect is very similar to what we've discussed before: all changes will be combined just as with a normal merge - but by using the -squash option, instead of a merge commit being automatically created, you're left with local changes in your working copy which you can then commit yourself. Squashing is also an option when merging branches: $ git merge -squash feature/loginĪutomatic merge went well stopped before committing as requested In case you are using the Tower Git client, using Interactive Rebase to squash some commits is very simple: just select the commits you want to combine, right-click any of them, and select the "Squash Revisions." option from the contextual menu. If you mark one or more lines as "squash", they will be combined with the one above:Īfter entering a commit message for the new, combining commit, the Interactive Rebase is completed - and the three old commits have been squashed into one. Keep in mind that Interactive Rebase allows to perform many different actions on your commit history for our example case here, however, we are interested in the "squash" action keyword. We can do so by starting an Interactive Rebase session: $ git rebase -i HEAD~3Īn editor window will then open where you can choose how you want to manipulate the selected part of your commit history. But before doing so, you'd like to clean up and squash the new commits into a single one: Let's say you have completed your work on a new feature branch (in the below example "feature/login") and now want to merge it back into the "main" branch. ![]() Going deep into Interactive Rebase goes beyond the scope of this article (take a look at the First Aid Kit for Git for a series of free, short videos on this topic), but we'll walk through a simple example case together. You can manually squash your commits at any time using Git's "Interactive Rebase" feature. In this post, we'll talk about Interactive Rebase and Merge as the two main ways to squash commits. There are different ways and tools when it comes to squashing commits. There are pros and cons to both approaches, so it's mostly a matter of preference and convention. However, you cannot say that (a) or (b) is the "correct" way of doing things. This can be helpful in keeping things orderly! Some teams see a possible advantage in going with (a) and using squash: instead of many individual commits which might be unnecessary and potentially overwhelming, only a single commit appears in the main commit history.
