Probably these are very trivial things. Sorry to ask them but would like to understand.
If I write (1): \version "2.19.82" $(object->string (+ 3 2)) Lilypond is happy and compile to a pdf file showing "5". Even this simpler code works... (2) \version "2.19.82" $"Hello" and generate a pdf file showing "Hello". It is clear to me that $ introduce a scheme expression that is evaluated. And in the previous two examples the scheme code is evaluated to strings. But I don't understand why lilypond outputs them. If I write (3): \version "2.19.82" "Test" this does not compile. So I would think that the "correct" code to output evaluated expression in the pdf file should be (4) \version "2.19.82" \markup $(object->string (+ 3 2)) or this (5) \version "2.19.82" \markup $"Hello" Why the behaviour of (1) and (2) ? * * * I tried to rewrite (1) and (2) with the hash mark instead of dollar (6): \version "2.19.82" #(object->string (+ 3 2)) and (7): \version "2.19.82" #"Hello" This time, there is no output in the pdf file. Why this difference? Thank you, g.
