These are all contained within the exercises/exercise_utils module.

These are loaded when downloading an exercise, which means that the app has access to these functions.

Available utility functions

There are functions broadly for the following categories:

• exercise_utils.cli: Generic CLI calls
• exercise_utils.file: File creation/appending
• exercise_utils.git: Common Git operations like commit, initializing a repository, and adding files
• exercise_utils.gitmastery: Git-Mastery specific functions like creating the start tag

Contributing utility functions

These should cover around 80% of all use cases, but if there isn’t an existing utility function for your use case, exercise_utils.cli.run_command is available to execute any other CLI calls.

If you believe that more utility functions should be supported, feel free to open a PR adding one.

If you add a new file, for example exercise_utils/general.py, please update app to include the file in the EXERICSE_UTILS_FILES constant here.
