Hello,
I have written a Scheme function to automatically produce all parts
given through a symbol-list. Here is a boiled-down, dummy example:
%%%%%%%%%%%%
\version "2.19.28"
printParts =
#(define-scheme-function (abbrs) (symbol-list-or-symbol?)
(let ((abbrs (if (symbol? abbrs) (list abbrs) abbrs))
(process-part (lambda (abbr)
(print-book-with-defaults
#{
\book {
\bookOutputName #(string-append
"wrap-multiple-books-"
(symbol->string abbr))
\score { c }
\paper { #(set-paper-size "a10") indent = 0 }
\header { tagline = ##f }
}
#}))))
(map process-part abbrs)))
\printParts one.two
%%%%%%%%%%%%
This compiles fine inasmuch as the output is just as intended, but it
does sport a:
<0>"/home/simon/lilypond/tests/wrap-multiple-books.ly:17:1: error: bad
expression type
\printParts one.two"
Is this worth a bug report about this error appearing too easily?
No. You use map instead of for-each,
