![]() ![]() ![]() Syncing Submodules With Main Repository.Remember, submodules pin a specific commit, so if the submodule's original repository advances further, you'd need to navigate to the submodule directory and pull the desired changes, then commit that new state in the main project. Register the submodule path(s) in your local configuration.įetch and checkout the appropriate commit from the submodule repository. # This will clone the 'repo' from 'user' into 'external/repo' directory in your main project. Once chosen, you'll utilize the git submodule add command. To begin setting up a submodule, you first need to decide on the repository you want to embed. They allow you to maintain a clear separation between your main project and its dependencies, all the while ensuring seamless integration between them. When working on a larger project, there are times when it's advantageous to pull in external repositories. In essence, while the submodule remains a part of your main repository structure, its version history and changes remain independent. However, if you navigate inside and run git status, you'll see the status of the submodule repository, not your main repository. Once you have added the submodule, navigating to it is just like navigating to any other directory within your repository. This will also include the reference to the specific commit of the submodule repository. Remember, after adding the submodule, you need to commit the changes to your main repository to finalize the addition. This file keeps track of all of your submodules and their corresponding URLs. gitmodules will be created or updated in the root of your main repository. # This will clone the 'library' repo into 'libs/library' directory of your main repo.Īfter running the command, you'll notice two things:Ī new directory libs/library will be created in your main repo, containing the contents of the library repository.Ī new file called. The basic syntax for adding a submodule is as follows: git submodule add įor example, if you wanted to add a submodule that points to a repository with URL and wanted it to reside in a directory called libs/library in your main repository, the command would be: git submodule add libs/library You can lock your project to a specific version of the external repository if needed.It's easy to pull updates from the external repository.Your main repository remains lightweight.Instead of duplicating that code in your project, you can use a submodule to reference the external repository. Submodules are particularly useful when you're working on a project that requires code from another repository. Instead of copying the entire codebase of the external project into your repository, you can simply reference it, ensuring that you can easily pull in updates or specific versions of that project. ![]() This feature is beneficial for projects that rely on external libraries or other projects. Ī Git submodule is essentially a mechanism in Git that allows you to include or embed one repository inside another as a sub-directory. Understanding its nuances can enhance your workflow and streamline your collaborative efforts. This mechanism lets you easily keep track of multiple projects that might be interdependent. Git submodules allow you to include or embed one or more repositories as a sub-folder inside another repository. ![]()
