Re: error :GUILE signaled an error for the expression beginning here #

Aaron Hill:

I would like to be able to see the *entire* command line, but when I write this:

%%%
\version "2.22.1"

#(define commandLine (object->string (command-line)))

\markup { \wordwrap { \commandLine } }
%%%

... the text scrolls off the page (see attached). I can guess why
\wordwrap doesn't work the way I want: it just sees one big string. Is
there a way to get the command line string to break or wrap at the
spaces?
