Personally, I think it would make more sense if people just placed
assignments to output-filename and output-suffix inside of the book's
paper block. That's straightforward to understand and does not require
keeping magical ordering relations in mind. \bookOutputName is more
like a compatibility API. A courtesy to keep around, but not as
straightforward in its implications.
this works:
bigMargin = \paper { top-margin = 10 \cm }
\book {
\paper {
\bigMargin
#(define output-filename "output-filename")
}
\relative {c d e f}
}
Ugh. Why don't you write
\paper {
\bigMargin
output-filename = "output-filename"
}
I found this weird expression in the docs - other forms are not
mentioned.
Ugh. Sounds worth fixing.
I will gladly apply the simple form now!
this not (because of the order):
\book {
\paper {
#(define output-suffix "output-filename")
\bigMargin
}
\relative {c d e f}
}
Hardly surprising now, is it, if you write it as _assignment_ rather
than as some weird Scheme block?
putting the assignment before \bigMargin still produces an error and
the output returns to default.
Exactly. A predefined output definition has (if at all) to come first
in any new output definition. The same with context definitions.
It is a bit weird how they find their target if not given.
\layout { \context { \Voice ... } }
manages to change the variable Voice in \layout's module. The reason is
not that this syntax would specify which variable to change: indeed,
\Voice just _fetches_ a copy of the variable Voice. But this variable
is a context definition containing a name = "Voice" definition, and
that's enough for this purpose. If you write
\layout { silly = \Voice
\context { \silly ... } }
then the changes end up in the definition of Voice, not in the
definition of silly, exactly because of that name = "Voice" def. Or
with
\layout { \context { \Voice name="TabVoice" ... } }
you redefine TabVoice starting from a copy of Voice (at least I think
so).
For output definitions, if you use them "naked" like
xxx = \paper { ... }
\book { \xxx }
then book knows to treat this like a paper because xxx has, in its
module, a variable is-paper set to #t.
