NAME

IO::Prompt::Timeout - Simple prompt interface with timeout.

SYNOPSIS

    use IO::Prompt::Timeout qw(:all);
    my $answer = prompt('Yes or No? (y/n)', %option);
    my $is_timeout = has_prompt_timed_out();

    # Specifying timeout seconds
    my $answer = prompt('Yes or No? (y/n) Answer in 10 seconds.', timeout => 10);

    # Specifying default answer
    my $answer = prompt('Yes or No? (y/n)', default => 'n');

DESCRIPTION

IO::Prompt::Timeout provides prompt subroutine most of which comes from ExtUtils::MakeMaker.

It also has timeout feature just like Prompt::Timeout. The default timeout seconds is 60. When prompt timed out, the default answer can be taken when it's set by option.

Unlike Prompt::Timeout, this module uses IO::Select for timeout procedure. The function of clearing timer by a single key click is not supported which is implemented in Prompt::Timeout.
