Perl6 / Rakudo: Wie konnte ich AutoFlush deaktivieren?

Question

Ich habe das versucht, aber es funktionierte nicht: generasacodicetagpre.

Answer 1

$*OUT.autoflush = False should disable it, and it runs without error, but it seems that parrot's IO still flushes automatically. So there currently doesn't seem to be an easy way.

Answer 2

Rakudo doesn't support autoflush. There's a note in 5to6-perlvar under the $OUTPUT_AUTOFLUSH entry.

Some examples from a long time ago mention an autoflush method, but that has disappeared:

$*ERR.autoflush = True;
$*ERR.say: "1. This is an error";
$*OUT.say: "2. This is standard out";

But that doesn't work:

No such method 'autoflush' for invocant of type 'IO::Handle'

I haven't seen any discussions about when this might show up as a feature, or a proclamation that it will never be a feature.
