I'll check for your recent changes soon.
Apart from a nit (below) all looks great now.
You did not extend section "Introduction to extending - Printing
values" with other printing procedures.
Mentioned are `display' and `write' from scheme and `ly:message'. In a
later section `displayMusic' and `display-scheme-music'.
Okay, I forgot about this one. I added
some text about (ice-9 format) (not
pretty-print, see below).
Nowadays it's very rare I use `display', `write' or `ly:message',
because all of them don't print (a)lists in a readable structered
format, although my codings always proceed with lots and lots of
printed data.
I nearly always use `pretty-print' and for music-expressions
`display-scheme-music'
I'd like to suggest to mention `pretty-print', at least for printing lists. See:
{
\override Slur.after-line-breaking =
#(lambda (grob)
(let ((cps (ly:grob-property grob 'control-points)))
(display-scheme-music cps)
(pretty-print cps)
(ly:message "~a" cps)
))
b'1( b'')
}
->
(list (cons 0.732364943841144 1.195004)
(cons 1.76258769418946 3.05939544438528)

A pity that ly:message does not accept the ~y-formatter.
Now go review https://gitlab.com/lilypond/lilypond/-/merge_requests/721. ;-)
So far the link to the guile manual about format-options may lead wrongly.
Btw, you link to guile-3.0.5 ...
Indeed, thanks for spotting. Fixed now.
Best regards,
Jean
