TODOs:
The workflow still needs to:

• create new branch
• commit changes
• push (with access to repo) to remote
• open a PR
  For this PR to be considered ready for review.

Updating the copyright text in files

You can update the copyright text using the following command, replacing the old Copyright with latest year:

1. Install sd, alternative to sed: cargo install sd
2. To replace 2023 with 2024, run:
3. find . \( -path ./target -prune -o -path ./.git -prune \) -o -type f -exec sd "Copyright (C) 2017-2023" "Copyright (C) 2017-2024" {} \;

• we exclude .git and target folders and the README as it contains this string and will be replaced too.

TODO: fix env. variables

THIS_YEAR=$(date +%Y) && LAST_YEAR=$(date +%Y -d "-1 year") && find . \( -path ./target -prune -o -path ./.git -prune \) -o -type f -exec sd '2017-\$LAST_YEAR' '2017-\$THIS_YEAR' {} \;
