I need to clone a private repository from GitHub, but I only want to get a specific tag (so basically, cloning is actually the wrong term for it).
Now, the problem is that there are multiple options, and all of them don't really work out:
- GitHub offers tagged versions as archives, but they are not accessible via
wget (at least I could not figure out how).
- GitHub does not support archiving repositories.
- I could run a
git clone and then run a
git checkout to get to the version specified by the tag, but then I download more than I need, I am in detached head state, and all the remaining stuff stays on disk. Of course, I could clean this up manually, but … well, lots of work for a trivial task.
What is the best way to achieve what I want to do?
I think my question was not clear enough, hence I'm adding some more information: What I want is not only get to the revision marked by a tag, but I also want to remove the entire history. Basically, as if Git never existed, and all I ever had was this one single version of my code. Any hints?
Best How To :
I think you can do this with
git clone --single-branch:
Clone only the history leading to the tip of a single branch, either
specified by the --branch option or the primary branch remote’s HEAD
points at. When creating a shallow clone with the --depth option, this
is the default, unless --no-single-branch is given to fetch the
histories near the tips of all branches. Further fetches into the
resulting repository will only update the remote-tracking branch for the
branch this option was used for the initial cloning. If the HEAD at the
remote did not point at any branch when --single-branch clone was made,
no remote-tracking branch is created.
Note that this says you need a branch to be specified with
--branch, rather than a tag. However, the documentation for
--branch , -b
Instead of pointing the newly created HEAD to the branch pointed to by
the cloned repository’s HEAD, point to branch instead. In a
non-bare repository, this is the branch that will be checked out.
--branch can also take tags and detaches the HEAD at that commit in the
The last sentence says you can use
--branch with a tag. The only thing I'm not sure of is whether you can both use
--single-branch and pass a tag to
--branch. I guess you will have to try that to confirm. Alternatively, you will have to create a branch in the remote repository as opposed to a tag.
You now say you also want to destroy the entire history. Do this afterwards.
git clean -xdf # Clean out everything not in git
rm -rf .git # remove git
git init . # put it back
git add . # Add all the files
git commit -a -m "Eternal sunshine of the spotless mind"
Living less dangerously
git rebase --root -i # needs recent version of git
then change every line to begin with
s to squash into the original commit.
