The test is considerably more sophisticated than: -t *ARGV && -t *STDOUT as it takes into account the magic behaviour of '*ARGV'. You can also pass 'is_interactive' a writable filehandle, in which case it requires that filehandle be connected to a terminal (instead of the currently selected). The usual suspect here is '*STDERR': if ( is_interactive(*STDERR) ) { carp $warning; } * 'interactive()' This subroutine returns '*STDOUT' if 'is_interactive' is true. If 'is_interactive()' is false, 'interactive' returns a filehandle that does not print. This makes it easy to create applications that print out only when the application is interactive: print {interactive} "Please enter a value: "; my $value = <>; You can also pass 'interactive' a writable filehandle, in which case it writes to that filehandle if it is connected to a terminal (instead of writing to '*STDOUT'). Once again, the usual suspect is '*STDERR': print {interactive(*STDERR)} $warning; * 'busy {...}' This subroutine takes a block as its single argument and executes that block. Whilst the block is executed, '*ARGV' is temporarily replaced by a closed filehandle. That is, no input from '*ARGV' is possible in a 'busy' block. Furthermore, any attempts to send input into the 'busy' block through '*ARGV' is intercepted and a warning message is printed to '*STDERR'. The 'busy' call returns a filehandle that contains the intercepted input. A 'busy' block is therefore useful to prevent attempts at input when the program is busy at some non-interactive task. %prep %setup -q -n %{cpan_name}-%{version} %build %{__perl} Makefile.PL INSTALLDIRS=vendor %{__make} %{?_smp_mflags} %check %{__make} test %install %perl_make_install %perl_process_packlist %perl_gen_filelist %files -f %{name}.files %defattr(-,root,root,755) %doc Changes examples LICENSE %changelog
