Well, from here it looks you used “” ‘’ -signs instead of " and '. But even with correct ones your example will fail. But you could do (at least on Linux): lilydevel -e "(begin (define myhash (make-hash-table))(hashq-set! myhash 'foo \"bar\"))" file.ly and in file.ly #(use-modules (guile-user)) #(write (hashq-ref myhash 'foo)) returning "bar" as wished. Otoh, I think the -e option is not very convenient for longer and/or complex expressions.
