is it possible to take a music expression and print out its literal

Sort of.
In other words: Could I write a function "\example" that takes a music
expression as an argument and that first outputs the input code as
text and then as a score?
So that
\example {
\relative c' {
c8 d e
}
}
Well, if you write
example =
#(make-scheme-function (parser location music) (ly:music)
...
then (ly:input-both-locations location)
will return
-- Function: ly:input-both-locations sip
Return input location in SIP as ‘(file-name first-line first-column
last-line last-column)’.
So you'll be able to take the input location information and read the
corresponding source from the file.
So you mean I should parse this (example result):
(/tmp/frescobaldi-4Orug3/tmp8Y5V5X/document.ly 8 0 16 1)
open the file (separately) from Scheme and read the given range?
You're right, that looks somewhat awkward but whould give me a start.
Thanks
Urs
It is sort of annoying that LilyPond does not offer something already
doing that since it _does_ have the information available (as you can
see when it produces error messages).
