no-book
No book is open.
Cause. The method works on a book and the server has none open. A server holds one book at a time, and starts
with none unless it was given --book.
Fix. Call book.open with the path of an existing book, or book.create
for a new one. red-ale exec --book <file> opens it for you. Methods that need no book (help.*, config.*,
period.*) never fail this way.
