Combined from primary sources listed below.

In IO::Handle§

See primary documentation in context for method t. 

method t(IO::Handle:D: --> Bool:D)

Returns True if the handle is opened to a TTY, False otherwise.

In IO::CatHandle§

See primary documentation in context for method t. 

method t(IO::CatHandle:D: --> Bool:D)

Calls .t, which tells if the handle is a TTY, on the currently active source handle and returns the result. If the source handle queue has been exhausted, returns False.

(my $f1 = 'foo'.IO).spurt: 'foo';
with IO::CatHandle.new: $f1, $*IN {
    repeat { .t.say } while .next-handle; # OUTPUT: «False␤True␤»
}
