"print" not showing immediately in output, but "puts" is

Several times I have come across this issue. It seems to be dependent on
the environment, but I’ll do a “print ‘string’” and it wont show up
UNTIL I do a “puts”. Then both strings will show up in the output window
in one shot.

Do you know how I can fix it to work properly?

It’s your terminal doing line buffering on the output.

Try:
$stdout.flush = true

Then see how it works for you.

Thanks for the information Rob.

Should I run this line before each “print” command or do I just need to
run it once upon application startup?

great, that seems to do it.

STDOUT.flush needs to be put after output, but before a gets call, for
example… however, STDOUT.sync=true can be done just once, and it sets
the
output to be flushed each time there is output.
