is Exception
Several methods from Proc::Async
expect that the external program has been spawned (by calling .start
on it), including say
, write
, print
and close-stdin
. If one of those methods is called before .start
was called, they throw an exception of type X::Proc::Async::MustBeStarted
.
Proc::Async.new('echo', :w).say(42);CATCH ;# OUTPUT: «X::Proc::Async::MustBeStarted: Process must be started first before calling 'say'»
