#f is often just interpreted as nil or null. So
\override NonMusicalPaperColumn #'page-break-permission = ##f
would be something like
NonMusicalPaperColumn.page-break-permission = null
in another language.

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

In order for this to be compiled without errors you'd have to write

freeformat = ##f

#f
is the Scheme representation of "false"
and you need the second # to tell LilyPond that there is going to be a 
Scheme expression.


But you don't use that value in your code, so what is it for?

PS: Btw, this documented here:
http://lilypond.org/doc/v2.16/Documentation/internals/nonmusicalpapercolumn

PPS: If you put this in the layout block, they are valid for each point
in time and thus line breaks or page breaks are allowed or forced at
each barline.

Hi Tom,

both the line- and the page-break-permissions expect one of these key
words: 'allow or 'force and not boolean values (#t or #f).

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

HTH,
Joram
