#+title: How to Clonse All Repositories from a GitHub or Sourcehut Account
#+description:
#+slug: clone-github-repos
* Cloning from GitHub
If you're like me and use a lot of different devices (and sometimes
decide to just wipe your device and start with a new OS), you probably
know the pain of cloning all your old code repositories down to your
local file system.
If you're using GitHub, you can easily clone all of your code back down
in just seconds. First, create a bash script. I do so by opening a new
file in =nano=, but you can use =gedit=, =vim=, or something else:
#+begin_src sh
nano clone_github_repos.sh
#+end_src
Next, paste in the following information. Note that you can replace the
word =users= in the first line with =orgs= and type an organization's
name instead of a user's name.
#+begin_src sh
CNTX=users; NAME=YOUR-USERNAME; PAGE=1
curl "https://api.github.com/$CNTX/$NAME/repos?page=$PAGE&per_page=100" |
grep -e 'git_url*' |
cut -d " -f 4 |
xargs -L1 git clone
#+end_src
Finally, save the bash script and make it executable.
#+begin_src sh
chmod a+x clone_github_repos.sh
#+end_src
Now you can run the script and should see the cloning process begin.
#+begin_src sh
./clone_github_repos.sh
#+end_src
* Cloning from Sourcehut
I haven't fully figured out how to directly incorporate Sourcehut's
GraphQL API into a bash script yet, so this one will take two steps.
First, log-in to Sourcehut and go to their
[[https://git.sr.ht/graphql][GraphQL playground for Git]]. Next, paste
the following query into the left box:
#+begin_src sh
query {
me {
canonicalName
repositories() {
cursor
results {
name
}
}
}
}
#+end_src
The output on the right side will give you an object of all your
repositories. Just grab that text and remove all the characters such as
quotation marks and curly brackets. You will need a single-line list of
space-separated values for the next step.
Now let's create the bash script:
#+begin_src sh
nano clone_sourcehut_repos.sh
#+end_src
Next, paste the following bash script in with the list of repositories
you obtained above and replace =your-username= with your username.
Note that this uses the SSH-based Git cloning method
(e.g. =git@git...=), so you'll need to ensure you have set up Sourcehut
with your SSH key.
#+begin_src sh
repos=(repo1 repo2 repo3)
# List all sub-directories in the current directory
for repo in "${repos[@]}"
do
# Clone
git clone git@git.sr.ht:~your-username/$repo
done
#+end_src
Finally, save the bash script and make it executable.
#+begin_src sh
chmod a+x clone_sourcehut_repos.sh
#+end_src
Now you can run the script and should see the cloning process begin.
#+begin_src sh
./clone_sourcehut_repos.sh
#+end_src
* Moving Repositories to a New Host
Now that you have all of your code repositories cloned to your local
computer, you may want to change the remote host (e.g., moving from
GitHub to GitLab). To do this, let's create another bash script:
#+begin_src sh
nano change_remote_urls.sh
#+end_src
Past the following information and be sure to change the URL information
to whichever host you are moving to. For this example, I am looping
through all of my cloned GitHub directories and changing them to
Sourcehut (e.g. =<YOUR_NEW_REMOTE_URL>= -> =git@git.sr.ht:~myusername=).
#+begin_src sh
# List all sub-directories in the current directory
for dir in */
do
# Remove the trailing "/"
dir=${dir%*/}
# Enter sub-directory
cd $dir
# Change remote Git URL
git remote set-url origin <YOUR_NEW_REMOTE_URL>/"${dir##*/}"
# Push code to new remote
git push
# Go back to main directory
cd ..
done
#+end_src
Finally, save the bash script and make it executable.
#+begin_src sh
chmod a+x change_remote_urls.sh
#+end_src
Now you can run the script and should see the cloning process begin.
#+begin_src sh
./change_remote_urls.sh
#+end_src
