%description
|
|
This module provides three utility subroutines that make it easier to
|
|
develop interactive applications...
|
|
|
|
* 'is_interactive()'
|
|
|
|
This subroutine returns true if '*ARGV' and the currently selected
|
|
filehandle (usually '*STDOUT') are connected to the terminal. 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
|
|
writinbg 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.
