But why? It is fine if you want to override them because you dislike
some default, but Jitter's classes are VM-independent, and only deal
with VM code and disassembly. There is nothing directly interesting for

The fact that you are *not* using out when doing your own printing is
more interesting, to me. Your printer, if I understand correctly,
relies on the output being on stdout, and it would misbehave if you
wanted to print a VM program to stderr or to an actual file, for

As long as I am not misunderstanding, your solution is good as a
temporary fix. But a good printer API should support output to any
Of course in the good printer API the FILE * argument will be replaced
by something more abstract -- but not a libtextstyle stream, because
libtextstyle might be unavailable or disabled. It will be something
And still, even if the printer received a libtextstyle stream as a
parameter, that would not be helpful to you: my output style is for
printing Jittery VM routines, while yours is for printing Poke's data.
So they would be two different, incompatible streams.
The literal printer should only see yours.
