GitHub supports Subversion clients via the HTTPS protocol. We use a Subversion bridge to communicate svn commands to GitHub.
The first thing you'll want to do is a Subversion checkout. Since Git clones keep the working directory (where you edit files) separate from the repository data, there is only one branch in the working directory at a time.
Subversion checkouts are different: they mix the repository data in the working directories, so there is a working directory for each branch and tag you've checked out. For repositories with many branches and tags, checking out everything can be a bandwidth burden, so you should start with a partial checkout.
On GitHub, navigate to the main page of the repository.
Above the list of files, click Code.
To clone the repository using HTTPS, under "Clone with HTTPS", click . To clone the repository using an SSH key, including a certificate issued by your organization's SSH certificate authority, click Use SSH, then click . To clone a repository using GitHub CLI, click Use GitHub CLI, then click .
Make an empty checkout of the repository:
$ svn co --depth empty https://github.com/user/repo > Checked out revision 1. $ cd repo
trunkbranch. The Subversion bridge maps trunk to the Git HEAD branch.
$ svn up trunk > A trunk > A trunk/README.md > A trunk/gizmo.rb > Updated to revision 1.
Get an empty checkout of the
branchesdirectory. This is where all of the non-
HEADbranches live, and where you'll be making feature branches.
$ svn up --depth empty branches Updated to revision 1.
You can also create branches using the Subversion bridge to GitHub.
From your svn client, make sure the default branch is current by updating
$ svn up trunk > At revision 1.
Next, you can use
svn copy to create a new branch:
$ svn copy trunk branches/more_awesome > A branches/more_awesome $ svn commit -m 'Added more_awesome topic branch' > Adding branches/more_awesome > Committed revision 2.
You can confirm that the new branch exists in the repository's branch dropdown:
You can also confirm the new branch via the command line:
$ git fetch > From https://github.com/user/repo/ > * [new branch] more_awesome -> origin/more_awesome
After you've added some features and fixed some bugs, you'll want to commit those
changes to GitHub. This works just like the Subversion you're used to. Edit your files, and use
svn commit to record your changes:
$ svn status > M gizmo.rb $ svn commit -m 'Guard against known problems' > Sending more_awesome/gizmo.rb > Transmitting file data . > Committed revision 3. $ svn status > ? test $ svn add test > A test > A test/gizmo_test.rb $ svn commit -m 'Test coverage for problems' > Adding more_awesome/test > Adding more_awesome/test/gizmo_test.rb > Transmitting file data . > Committed revision 4.
To switch between branches, you'll probably want to start with a checkout of
$ svn co --depth empty https://github.com/user/repo/trunk
Then, you can switch to another branch:
$ svn switch https://github.com/user/repo/branches/more_awesome
GitHub's Subversion server exposes the Git commit sha for each Subversion commit.
To see the commit SHA, you should ask for the
git-commit unversioned remote property.
$ svn propget git-commit --revprop -r HEAD https://github.com/user/repo 05fcc584ed53d7b0c92e116cb7e64d198b13c4e3
With this commit SHA, you can, for example, look up the corresponding Git commit on GitHub.
