Set up mergiraf

As the docs say, it’s best to install mergiraf as a merge driver

First grab the binary

cargo binstall mergiraf

Then configure git:

git config --global merge.mergiraf.name mergiraf
git config --global merge.mergiraf.driver 'mergiraf merge --git %O %A %B -s %S -x %X -y %Y -p %P -l %L'

Then make/edit your git config

mkdir -p ~/.config/git
echo '* merge=mergiraf' >> ~/.config/git/attributes

Lastly enable diff3 conflict style

git config --global merge.conflictStyle diff3
