bump_dev_version_nightly.yml

# This workflow is triggered at 3:00 AM CET everyday and checks if there has
# been a commit in the last 24 hours on the develop branch of tudat repository.

# If there has been a commit, it bumps the version in the develop branch of
# the tudat repository, creates a tag with the version numbers and pushes both
# the commit and the tag to the repository, and then bumps the version in the
# develop branch of the tudat-feedstock repository and pushes the commit and
# the tag to the repository.

# This workflow uses personal access tokens to push the changes to the repository. The personal access token is stored as a secret in the repository.

# This workflow file must be in the master (default branch) of the tudat repository because scheduled workflows are only triggered on the default branch.

# Reference for the logic to check if there has been a commit in the last 24 hours: https://stackoverflow.com/questions/4089430/how-can-i-determine-if-a-git-commit-is-more-recent-than-another-commit
