Re: Unaccepted #t

[Tom van der Hoeven]

Urs,

thank for you quick reply.
I am translating pieces with clef alto to clef treble
First step by just copy the original.
At checking time I want to be in sink with the original
Second step clef treble and free format, because the spacing of Lilypond 
is the best.
For free format you need changes at 2 places.
The trick with mbreak = {} %\break
and give line break permission.
I want to handle them both with a boolean in the masterfile
freeformat = #t
or
freeformat = #f

So this is the underlying problem

Tom

Noeck,

\override NonMusicalPaperColumn #'line-break-permission = #'force
\override NonMusicalPaperColumn #'page-break-permission = #'allow

this solves the problem, but is is strange that

\override NonMusicalPaperColumn #'page-break-permission = ##f

is accepted

Tom
