Splitting GitHub releases - github

I just migrated an old project from an own Subversion/Trac infrastructure to GitHub
https://github.com/matteocorti/nagios_plugins
The repository contains one directory for each plugin I wrote. Each plugin is standalone and has an own version number (but the source code is in the same repository).
When I release a new plugin version I would like to have a release with just the corresponding folder (e.g., https://github.com/matteocorti/nagios_plugins/tree/master/check_updates)
Is there a way with the GitHub release feature to select which part of a repository contains the software to be released?
Another option would be to split the whole and have a repository for each plugin. This would imply that I will have to manually move all the issues/bugs and wiki pages.
Edit
It seems that the only solution would be to split the repository (a separate repository for each plugin).
How can I split a Git repository retaining the commit history?

It seems that the only solution would be to split the repository (a separate repository for each plugin).
It is, but that does not migrate wiki pages and issues.
To split a git repo while keeping the history, see GitHub page "Splitting a subfolder out into a new repository"
git clone https://github.com/YOUR-USERNAME/YOUR-REPOSITORY
git filter-branch --prune-empty --subdirectory-filter \
YOUR_FOLDER_NAME master
# Filter the master branch to your directory and remove empty commits
# Rewrite 48dc599c80e20527ed902928085e7861e6b3cbe6 (89/89)
# Ref 'refs/heads/master' was rewritten
The repository now contains all the files that were in your subfolder.
Note that although all of your previous files have been removed, they still exist within the Git history. You can now push your new local repository to a new repository on GitHub.
Check also "How to tear apart a repository: the Git way "
Once you have one repo per plugin, you can still register them in your original repo, as git submodules.
Edit
To push the subfolder to a new repository
git remote rename origin upstream
git remote add origin NEW_URL
git push origin master

Make the current commit the only (initial) commit in a Git repository that was created with GitHub Desktop

I created my first GitHub repository using GitHub Desktop (Windows). It is a real mess with many revisions that are quite meaningless and some versions of files that I would rather were never uploaded. This was the result of a lot of experimenting to get the feel for how things would appear on GitHub. I want to get rid of all the history versions.
I am tempted to just copy my files on my drive to another folder then delete the repository folder from my drive. Also delete it from GitHub.
Then create a new repository with GitHub Desktop, perhaps with the same name or with a different name then rename it to the original. Could it be a simple as that or will GitHub still retain the files somewhere?
I haven't tried this because in my searching I keep finding all the complex steps to be performed to remove histories or remove files.
I sort of feel that what I am proposing is too simple.
Any opinions?
All of this got too confusing.
I just did what I said in the start of the thread.
It seems GitHub Desktop has some Username/Password problem and won't let me "Publish branch".
So I went to GitHub and created a new repository and uploaded all the files from my local folder.
It looks good to me.
There may be problems in the future. I guess I'll cross that bridge when (if) I come to it.
An alternative approach is to switch to command line and:
delete the .git folder in your repository
recreate it (git init .)
reset the origin remote: git remote add origin https://github.com//
Make a first commit with your current content:
git add .
git commit -m "first commit"
overwrite everything on the remote repo
git push --force -u origin master
The end result will be the same repo but with only one commit.
You can then switch back to GitHub Desktop.
From here.
First make sure you have Git for Windows installed, you are going to need to do git commands manually sooner or later.
Go to your local repository on your computer where your project is located. It's a good idea to show hidden files so you can see that you have the .git-folder and that the .gitignore-file is in place.
Go to the folder where the .git-folder is, right-click and click git bash here.
Now enter these commands:
Create Orphan Branch – Create a new orphan branch in git repository. The newly created branch will not show in ‘git branch’ command.
git checkout --orphan temp_branch
Add Files to Branch – Now add all files to newly created branch and commit them using following commands. Don't forget .gitignore!
git add .
git commit -m "the first commit"
Delete master Branch – Now you can delete the master branch from your git repository.
git branch -D master
Rename Current Branch – After deleting the master branch, let’s rename newly created branch name to master.
git branch -m master
Push Changes – You have completed the changes to your local git repository. Finally, push your changes to the remote (Github) repository forcefully.
git push -f origin master

How to let github automatically track changes of an overleaf project?

I'm wondering if it is possible to let github automatically track changes when I make changes to an overleaf project.
Following the Overleaf documentation, you might consider adding an Overleaf Project as a Git Submodule
Each project on Overleaf gets its own git repo, but if you want to organise several such projects into one git repo on GitHub, you can add the repo for each project as a git submodule in the usual way.
You can then push and pull each submodule repository to/from Overleaf individually and still have them collected together as submodules in the project on GitHub.
Then a git submodule update --remote would automatically update your local repo with the latest from that submmodule.

GitHub - Pull changes from a template repository

I have created a Template Repository in GitHub and then created some repositories based on the template. Since they were created, there have been updates to the template that I want to pull into those repositories.
Is this possible?
On the other repositories you have to add this template repository as a remote.
git remote add template [URL of the template repo]
Then run git fetch to update the changes
git fetch --all
Then is possible to merge another branch from the new remote to your current one.
git merge template/[branch to merge] --allow-unrelated-histories
https://help.github.com/en/articles/adding-a-remote
I will link to the same location as HRK44 but my answer is very different.
https://help.github.com/en/articles/creating-a-repository-from-a-template
Although forks and templates are mentioned in the same section, they are very different.
One of the differences mentioned in the link is:
A new fork includes the entire commit history of the parent repository, while a repository created from a template starts with a single commit.
This basicly means that you will not be able to pull new changes from the template as your git histories are very different and are not based on the same thing.
If you do use the method mentioned in the accepted answer, you will have very hard manual merges that will result in changes to all of the files received from the template, even if they werent changed since the first time you created that repo from that template.
In short, creating a repo from a template (using only master branch) is the same process as:
git clone template
cd folder
rm -rf .git
git init
git remote add origin <new repo url>
git add .
git commit -m "Initial Commit"
git push -u origin master
A few other things that are not (surprisingly) copied when creating a repo from a template:
(Unless github fix this at a later point)
Repo configurations (allowed merge types, permissions etc)
branch rules
So when using this at your organization, make sure to set all repo configurations on the newly created repo.
If you want to merge changes from a template into your project, you're going to need to fetch all of the missing commits from the template, and apply them to your own repo.
To do this, you're going to need to know the exact commit ID that you templated from, and you're going to need to know the commit ID of your first commit.
ORIGINAL_COMMIT_ID=<commit id from original repo you templated from>
YOUR_FIRST_COMMIT=<first commit id in your repo>
YOUR_BRANCH=master
Next you're going to need add the template as a remote, and fetch it.
git remote add upstream git#github.com:whatever/foo.git
git fetch upstream
And finally, you need to rebase all of the commits you're missing onto your branch
git rebase --onto ORIGINAL_COMMIT_ID YOUR_FIRST_COMMIT YOUR_BRANCH
What this is doing it basically creating a branch off of ORIGINAL_COMMIT_ID, then manually applying all of the commits on your original branch, onto this new branch.
This leaves you with what you would have had, if you had forked.
From here, you can git merge upstream/master just as if you had forked.
Once you've completed your merge, you'll need to use git push --force to push all of the changes up to the remote. If you're working with a team, you'll need to coordinate with everyone when doing this, as you're changing the history of the repo.
Note: It's important to note that this is only going to apply to one branch. If you have multiple feature branches, you'll need to perform the same steps to each one.
#daniel's answer also did not work for me because of the unrelated histories problem mentioned in #dima's answer. I achieved the desired functionality by doing the following:
Copy the URL for the template repository you wish to use to create a new repository. (ex: https://github.com/<username>/my-template.git)
Use GitHub Importer to make a new repository based on the template repository.
This solves the unrelated histories problem because it preserves the entire commit history of the template repository.
You need to use the Importer because you cannot fork your own repository. If you want to use someone else's template repository, you can just fork theirs.
Then, add the template repository as a remote.
git remote add template https://github.com/<username>/my-template.git
After you make new commits to the template repository, you can fetch those changes.
git fetch template
Then, merge or rebase. I recommend to merge on public repos and rebase on private repos.
To merge
git checkout <branch-to-merge-to>
git merge template/<branch-to-merge>
To rebase
git checkout <branch-to-merge-to>
git rebase upstream/<branch-to-merge>
NOTE: When rebasing, you must
git push origin <branch-name> --force
in order to override your old commits on your remote branch. This is why I recommend to rebase only on private repos.
I approached this differently as fetch & merge was not ideal as lot of files diverge across template and downstream projects. I only needed the common elements to sync.
lets says we have the below folder structure locally:
repos
├── template_repo
└── downstream_repo
1. Now create a git patch from the parent folder (repos):
git diff --no-index --diff-filter=d --output=upstream_changes.patch -- downstream_repo/some_common_path template_repo/some_common_path
NOTE - the order of the paths matters!, downstream_repo comes first! (interpret this as "what are the changes we need to make to downstream_repo to make it same as template_repo"; look at the --name-status output, it will hopefully make sense.)
--no-index option generates git diff based on filesystem paths. Path can be a single file or a folder.
--diff-filter=d will ignore any files that are in the downstream_repo but not in the template_repo. This only applies when diffing folder paths.
You can use --stat, --name-status to see what the patch will contain.
Review the generated patch.
2. Change to downstream_repo folder and apply the patch
git apply -p2 ../upstream_changes.patch
explanation for -p<n> option from the official doc:
Remove leading path components (separated by slashes) from
traditional diff paths. E.g., with -p2, a patch against a/dir/file
will be applied directly to file. The default is 1.
Using -p2 will drop a/downstream_repo and b/template_repo from the diff paths allowing the patch to apply.
This is the reason for starting with above illustrated folder structure.
Once the patch is applied, rest of the process should be familiar.
All of these options are clearly explained in git diff and git apply official docs.
Another option is to create a patch from the necessary commits and move the patch to a new project
git format-patch -1 HEAD
Insert a patch
git am < file.patch
details are here
I ran into this same issue. I have 10+ projects all created from the same template project (react-kindling) and using git alone wasn't sufficient, as it would pull in changes to the template that I didn't want in my child projects.
I ended up creating an npm utility for updating child projects from template starter projects. You can check it out here:
LockBlocks
It's been a real life saver. Pulling changes from the template is a heck of a lot easier now.
This works too:
git remote add template git#github.com:org/template-repo.git
git fetch --all
git merge template/main --allow-unrelated-histories

Update a GitHub repository without cloning

Here's the situation, we are currently working on a project and lately we decided to upload it on GitHub. Now I made my changes and I want to push the changes onto the repository.
As far as I read, in order to make changes you need to clone the repository but that will download all files from the repository and I already have all of the source files.
I'm using GitHub desktop and I can't find any option to clone without downloading and update or create branches from my existing files. Creating a local one is an option but it needs to be uploaded as a separate repository instead of linking it to a current one.
Is there any way to push updates, create branches to the repository from my local project to an existing repository?
Your local project should already be a git repo, if you uploaded it to GitHub.
But in case it is not, switch to command-line, and do inside the root folder of your project (which should shows the same files as your remote repo):
git init .
git remote add origin https://github.com/<user>/<project>
git fetch
The fetch part will download the repo but leave your files alone.
(But do a backup still, just to be safe)
git branch master origin/master
git reset master
From there, your GitHub Desktop should show you any diff between your files and what was fetched from the repo.

Fork from a branch in github

Is there a way to fork from a specific branch on GitHub? … For example, moodle has many branches (1.9, 2.0 … and so on). Can a clone be performed of just branch 1.9 and not the master branch always? Is it possible to clone a specific branch onto my PC?
I don’t know a native way yet, but you can do it following this recipe:
Fork the repository in question (called ‘upstream’) on the GitHub website to your workspace there.
Run the GitHub desktop application and clone the repository onto your PC.
Use the GitHub desktop application to open a shell in the repository. (The git commands are not available from the default PowerShell unless you configure that manually.)
Set the source repository as upstream:
git remote add upstream https://github.com/{user}/{source-repo}.git
Fetch the full upstream repository. (Right now, you only have a copy of its master branch.)
git fetch upstream
Make your file system copy the branch you want and give it any name:
git checkout upstream/{branch-in-question}
git checkout -b temporary
Publish your repo using the GitHub desktop application.
On the GitHub website, open your repository and click ‘settings’.
Change the “Default branch” to ‘temporary’. (Just change the drop-down menu, you don’t need to click the “Rename” button.)
Go back to your repository, go to the ‘branches’ tab, now you can delete the “master” branch.
Delete the master branch on your shell and make a new master branch:
git branch -d master
git branch master
git checkout master
git -d temporary
Once more, publish your repo using the GitHub desktop application.
On the GitHub website, open your repository and click ‘settings’.
Change the “Default branch” back to the (new) ‘master’ branch.
Go back to your repository, go to the ‘branches’ tab, now you can delete the “temporary” branch.
This should be what you were looking for. Perhaps GitHub will provide a more convenient way to do this in future (e.g., clicking “Fork” from a project’s branch results in exactly this behaviour).
Cloning means that you create a copy of the whole repository in your account including all branches and tags. However you are free to switch and track branches however you like.
No command line needed. Just create a new branch in your forked repository in GitHub. GitHub will ask you if you want to clone/mirror this new branch from the upstream repository. You can give any name to the new branch.
Yes, you can clone the single branch. For example, you have a branch named release1.0. If you would like to clone this branch into your pc then use the following line of code:
$ git clone git#bitbucket.org:git_username/git_repository_example -b release1.0 --single-branch
For those who don't like working with command-line. Here is a simple guide using the desktop client for GitHub:
Click the fork button of the repo on GitHub.com:
Make sure you have the desktop client installed
Click this button:
Clone the repo
In the desktop client, select the desired branch
Select the branch you'd like to work on and you're done
I'm posting here the method I've used.
Like the OP I wanted to only copy/fork one branch. But couldn't find an easy way.
in your repo create a new branch. It doesn't need to have the same name as the branch you want to fork
once created, verify that it is the selected branch, and click "Compare"
reverse the order of comparison (I have a userscript for that, see my profile if it's something you want to test).
the "base" repository must be yours, with the branch you've created
the "head" repository is the original, and the branch is the branch you want to fork
hit "create pull request" and continue until the PR is applied
That's it. You have the branch forked.
I'm using bitbucket but I'm sure this would work for GitHub as well.
Create a new repository
Checkout the branch using GitExtensions
Click Push to open the Push dialog
Set the destination URL to the new repository
Set the destination branch to "master"
Push
Your new repository will have the full history of the one branch only (not all branches like forking will have).
A fast, alternative approach is to create your own new repo.
Go to https://github.com/new and make a new repo. Do not initialize with README.
Scroll down to get your git remote
Then:
git remote rm origin
git config master.remote origin
git config master.merge refs/heads/master
// Run code from above image
git push --set-upstream origin yourbranchname
You will have a new repo with the original repo's code and a branch that can be made into a pull request.
SOLUTION:
For remote repository on GitHub and local repository
After fork all branches to your GitHub repository, you can delete Redundant branches in your GitHub repository.
And then you can only clone the branches you need to local.
Step One
Step Two
Only For local repository
git clone -b <branch name> --single-branch <repository>
If you want to further save your disk space, you can clone remote repository without history:
git clone -b <branch name> --depth 1 <repository>
notice: --depth implies --single-branch unless --no-single-branch is given.
https://git-scm.com/docs/git-clone
Switch to the branch you need in source repo
Click "Fork". You'll get forked master and the branch you're in.
I don't know how it works with more branches, but for my needs worked pretty well.
