## Git
### Split out subfolder into new repository
<details>
<summary>Steps</summary>
- *Be sure you are inside the original repo*
```sh
cd <orignal_repository>
```
- Set local variables for use
```sh
username=tobyvin-cs340
subdir=src/Plotter
newrepo="$(basename $subdir)"
oldrepo="$(pwd)"
```
- Create a new branch containing only the subdir using `git subtree`
```sh
git subtree split -P $subdir -b $newrepo
```
- Create a temp git repo and pull in the newly created branch
```sh
cd $(mktemp -d)
git init && git pull $oldrepo $newrepo
```
- Copy over the git artifacts from original repo's root directory
```sh
cp $oldrepo/.gitignore ./
cp $oldrepo/.gitattributes ./
```
- Commit changes
```sh
git add -A && git commit -m "split out $newrepo into submodule"
```
- Create the repository on a remote (github) and push
```sh
gh repo create $username/$newrepo
git push -u origin master
```
- Switch back into the original repository
```sh
cd $oldrepo
```
- Remove the subdir from git and the filesystem
```sh
git rm -rf $subdir
rm -rf $subdir
```
- Add the newly created remote repository as a submodule at the subdir's path
```sh
git submodule add git@github.com:$username/$newrepo $subdir
git submodule update --init --recursive
```
- Commit the changes to the original repository and push to remote
```sh
git commit -m "split out $newrepo into submodule"
git push -u origin master
```
