#working_directory_copasetic?(options = {}) ⇒ Boolean

A short user prompt if there are uncommitted changes in the repo, in case the user forgets before they deploy. Naturally, one may cancel this process effectively cancelling the entire deploy cleanly. This occurs before any hard changes (e.g., writing changes, pushes, command execution, etc.) are made.

Returns:

  • (Boolean)
