See the pursuing script:
I person developed a tiny experimental task A successful its ain Git repo. It has present matured, and I'd similar A to beryllium portion of bigger task B, which has its ain large repository. I'd present similar to adhd A arsenic a subdirectory of B.
However bash I merge A into B, with out dropping past connected immoderate broadside?
If you privation to merge subdivision some-branch from project-a into project-b:
cd path/to/project-agit checkout some-branchcd path/to/project-bgit remote add project-a /path/to/project-agit fetch project-a --tagsgit merge --allow-unrelated-histories project-a/some-branchgit remote remove project-aTaken from: git merge antithetic repositories?
This methodology labored beautiful fine for maine, it's shorter and successful my sentiment a batch cleaner.
Successful lawsuit you privation to option project-a into a subdirectory, you tin usage git-filter-repo (filter-branch is discouraged). Tally the pursuing instructions earlier the instructions supra:
cd path/to/project-agit filter-repo --to-subdirectory-filter project-aAn illustration of merging 2 large repositories, placing 1 of them into a subdirectory: https://gist.github.com/x-yuri/9890ab1079cf4357d6f269d073fd9731
Line:
The --allow-unrelated-histories parameter lone exists since git >= 2.9. Seat Git - git merge Documentation / --let-unrelated-histories
Replace:
Added --tags arsenic advised by @jstadler successful command to support tags.
Present are 2 imaginable options:
Submodules
Both transcript repository A into a abstracted listing successful bigger task B, oregon (possibly amended) clone repository A into a subdirectory successful task B. Past usage git submodule to brand this repository a submodule of a repository B.
This is a bully resolution for loosely-coupled repositories, wherever improvement successful repository A continues, and the great condition of improvement is a abstracted base-unsocial improvement successful A. Seat besides SubmoduleSupport and GitSubmoduleTutorial pages connected Git Wiki.
Subtree merge
You tin merge repository A into a subdirectory of a task B utilizing the subtree merge scheme. This is described successful Subtree Merging and You by Markus Prinz.
git remote add -f Bproject /path/to/Bgit merge -s ours --allow-unrelated-histories --no-commit Bproject/mastergit read-tree --prefix=dir-B/ -u Bproject/mastergit commit -m "Merge B project as our subdirectory"git pull -s subtree Bproject master(Action --allow-unrelated-histories is wanted for Git >= 2.9.Zero.)
Oregon you tin usage git subtree implement (repository connected GitHub) by apenwarr (Avery Pennarun), introduced for illustration successful his weblog station A fresh alternate to Git submodules: git subtree.
I deliberation successful your lawsuit (A is to beryllium portion of bigger task B) the accurate resolution would beryllium to usage subtree merge.
Merging 2 Git repositories tin look daunting, however it's a essential project successful galore improvement workflows. Whether or not you're consolidating initiatives, integrating libraries, oregon reorganizing your codebase, knowing the appropriate strategies is important. This station volition usher you done the about communal and effectual methodology: utilizing Git subtree. We'll research however to efficaciously combine 1 repository into different, preserving past and sustaining a cleanable task construction. This ensures a creaseless collaboration and businesslike task direction. Fto's dive into however you tin accomplish this seemingly analyzable cognition with comparative easiness and precision.
Knowing Git Subtree for Repository Merging
Git subtree is a almighty characteristic that permits you to merge 1 repository into a subdirectory of different, piece preserving the perpetrate past of some initiatives. This is peculiarly utile once you privation to see an outer task (similar a room oregon a module) straight into your chief task's repository with out shedding its first improvement past. Dissimilar easier strategies similar copying information, subtree merge maintains a broad evidence of wherever the codification originated and permits you to easy replace the built-in task with modifications from its first repository. Appropriate usage of Git subtree ensures that your task stays organized and that contributions are precisely tracked, making it an indispensable accomplishment for immoderate capital Git person.
Wherefore Take Git Subtree Complete Another Strategies?
Git subtree gives chiseled advantages complete another strategies similar Git merge oregon merely copying information. Git merge tin beryllium analyzable and frequently outcomes successful a messy perpetrate past once integrating unrelated repositories. Copying information, connected the another manus, wholly discards the first task's past, making it hard to path modifications and updates. Git subtree elegantly solves these issues by embedding the full task, together with its past, into a subdirectory. This preserves the integrity of some initiatives and permits for seamless synchronization of modifications betwixt them. This attack is particularly generous once you demand to support the built-in task ahead-to-day with the newest developments from its first origin. This gives a structured, traceable, and maintainable integration procedure.
Fto's expression astatine a examination:
| Methodology | Professionals | Cons |
|---|---|---|
| Git Subtree | Preserves past, permits synchronization, cleanable integration | Somewhat much analyzable instructions |
| Git Merge | Elemental for associated repositories | Messy past, hard for unrelated repositories |
| Copying Information | Precise elemental | Loses past, nary synchronization |
Steps to Merge Repositories Utilizing Git Subtree
The procedure of merging 2 repositories utilizing Git subtree includes respective cardinal steps. Archetypal, you'll adhd the outer repository arsenic a distant to your chief task. Past, you'll usage the git subtree adhd bid to merge the outer repository into a circumstantial subdirectory inside your task. Last the merge, you whitethorn demand to propulsion the modifications to your distant repository to brand them disposable to others. Eventually, you tin propulsion behind early updates to that outer task into your task with the git subtree propulsion bid. These steps guarantee that the integration is creaseless, and the past of some repositories is decently preserved. This methodology is particularly utile once integrating 3rd-organization libraries oregon modules into your chief task.
- Adhd the outer repository arsenic a distant:
git remote add -f <remote_name> <remote_url> - Merge the outer repository into a subdirectory:
git subtree add --prefix=<subdirectory> <remote_name> <branch> --squash - Propulsion the modifications to your distant repository:
git push origin <your_branch> - Propulsion early updates:
git subtree pull --prefix=<subdirectory> <remote_name> <branch> --squash
For illustration, to adhd a room known as "my-room" from a distant URL and merge it into a listing known as "libs/my-room", you would tally:
git remote add -f my-library https://github.com/example/my-library.git git subtree add --prefix=libs/my-library my-library main --squash git push origin main "Git subtree gives a cleanable and organized manner to combine outer repositories into your task, preserving past and facilitating updates."
Knowing these instructions and their appropriate utilization is important for sustaining a fine-structured and manageable Git repository.

To guarantee a creaseless and businesslike workflow once utilizing Git subtree, it's indispensable to travel definite champion practices. Recurrently replace the built-in task with the newest modifications from its first repository to support your task actual. Usage descriptive perpetrate messages to intelligibly bespeak once you're merging modifications from the subtree. Debar making nonstop modifications inside the subtree listing; alternatively, lend modifications backmost to the first repository at any time when imaginable. This helps keep the integrity of the first task and ensures that your contributions payment the wider assemblage. Adhering to these practices volition brand your Git subtree workflow much effectual and little inclined to errors. For much successful-extent insights, see exploring assets similar Atlassian's Git Subtree tutorial.
- Recurrently replace the subtree.
- Usage broad perpetrate messages.
- Debar nonstop modifications inside the subtree.
Moreover, see the pursuing suggestions:
- Ever usage the --squash action to make a azygous perpetrate for the merged modifications, retaining your past cleanable.
- Automate the replace procedure with scripts oregon CI/CD pipelines for predominant integrations.
- Pass with the maintainers of the first repository astir immoderate important modifications you program to combine.
By incorporating these methods, you tin maximize the advantages of Git subtree piece minimizing possible problems. For much precocious strategies, mention to the authoritative Git documentation connected subtree.
Successful decision, knowing however to merge 2 Git repositories utilizing Git subtree is a invaluable accomplishment for immoderate developer running with aggregate initiatives oregon integrating outer libraries. By pursuing the steps and champion practices outlined supra, you tin efficaciously negociate your task's dependencies, sphere perpetrate past, and keep a cleanable and organized codebase. Whether or not you are consolidating initiatives oregon incorporating 3rd-organization modules, Git subtree gives a sturdy and businesslike resolution. Clasp these strategies to streamline your workflow and heighten your collaboration capabilities.
