Constructor Details

#initialize(command, undo = nil, opts = {}) ⇒ CliCommand

undo is an action that would be expected to reverse the consequences of this action. You can do without it if the action can’t fail, if it has no real consequences, or if a prior action, when undone, will wipe out those consequences. For example, if an earlier command created the directory that the current command is writing a file to, the earlier command would be expected to delete the directory.
