I was using writef("escape string" ~ "Display string") to try to simulate a console, but noticed that the writes are only flushed when a newline is present.

Is there a 'flush' function that works with stdio?
'flush()' seems unkown to the compiler, and 'fflush()' seems to be for files, not for writing to the screen.

You mean stdout.flush() ?

Don't forget seat.putDown() too!

Tried your idea, error message was:
"No property 'flush' for type '_iobuf'

Oh, and also forgot about hands.wash().

stdout should be a struct File if you imported std.stdio;


As if looks like the C stdout is taking precedence, you can either force
the use of it via std.stdio.stdout.flush() , or call fflush(stdout).

You can also try to call setvbuf on stdio with _IONBF mode to set it to non-buffering mode.

oops, stdout.
int zero=setvbuf(stdout,null,_IONBF,0);
assert(zero==0);

or

stdio.setvbuf(0,_IONBF);

Your suggestion of:

fflush(stdout);

worked.

Thank you.
