```bash
#!/usr/bin/env bash
set -eu -o pipefail

files=$(git ls-files | grep package.json)
pwd=$PWD

for file in $files; do
  echo "Adding repository to ${file} ..."
  dir=$(dirname $file)
  if [[ $dir == "." ]]; then
    npm pkg set repository.type="git" repository.url="https://github.com/percy/cli"
  else
    npm pkg set repository.type="git" repository.url="https://github.com/percy/cli" repository.directory="$dir" --workspace="$dir"
  fi
done

  }
