Clear and concise description of the problem

I want to remove empty lines from the code output so that the display is more compact.
I intend to submit a PR for this issue.

Suggested solution

In packages/transformers, we could provide a transformerRemoveEmptyLines that filters out lines containing only whitespace.

Alternative

None considered.

Additional context

None.
