Thanks for pointing this out.
with "write" I indeed see what I want to.
But when I try to pass that to a ly:message I'll get
Wrong type argument in position 1 (expecting string): ("critical-remark")
ly:message expects a string. You are passing it a list. That its first
element is a string does not change that.
The documentation says:
LY_DEFINE (ly_message, "ly:message",
1, 0, 1, (SCM str, SCM rest),
"A Scheme callable function to issue the message @var{str}."
" The message is formatted with @code{format} and @var{rest}.")
So you need a format string here.
You can write (ly:message "~s\n" your-variable) here and get what you
want output in Scheme form. If you don't want strings to be quoted, use
~a instead.
Thanks again. Now I see that this actually is what you already referred
you in your previous email.
Still driving me crazy all this ...
+1
You know you are agreeing with yourself?
Yes.
I wanted to express my frustration about the fact that yesterday I
thought I'd understood the issue and this morning - after changing a
tiny bit - I'm as dumb as before. ;-)
When in doubt, use
git grep
on the LilyPond code base to find usage examples for functions. I see
dak@lola:/usr/local/tmp/lilypond$ git grep ly:message
Documentation/contributor/programming-work.itexi:@tab @code{(ly:message msg args
input/regression/loglevels.ly:#(ly:message "Test message\n")
lily/warn-scheme.cc:LY_DEFINE (ly_message, "ly:message",
po/zh_TW.po:#. (ly:message (_ "Converting to `~a'...")
scm/backend-library.scm: (ly:message (_ "Converting to `~a'...\n") pdf-name)
scm/backend-library.scm: (ly:message (_ "Converting to ~a...") "PNG")
scm/backend-library.scm: (ly:message (_ "Writing header field `~a' to `~a'...")

scm/graphviz.scm: (ly:message (format #f (_ "Writing graph `~a'...") (port-fi
scm/lily.scm: (else (ly:message ""))))
scm/lily.scm: (ly:message
scm/lily.scm: (ly:message
scm/lily.scm: (ly:message (_ "Redirecting output to ~a...") log-name)
scm/lily.scm: (ly:message "# -*-compilation-*-"))
scm/lily.scm: (ly:message (_ "Invoking `~a'...\n") cmd)
scm/music-functions.scm: (apply ly:message msg rest))))
scm/safe-lily.scm: ly:message
scm/song.scm: (ly:message "Writing Festival XML file ~a..." filename)
scm/song.scm: (apply ly:message message (map pp args))))
scm/stencil.scm: (ly:message "Writing ~a" outname)
anf there are a few examples fitting your use case.
Ah, I'd already grepped the git repo in the past, but didn't see it as a
standard means when looking up usage information. Thanks.
