Summary : Utilities for interactive I/O
Description :
This module provides three utility subroutines that make it easier to
develop interactive applications.
The 'ARGV' filehandle, the one that '<>' or an empty 'readline()' uses, has
various magic associated with it. It's not actually opened until you try to
read from it. Checking '-t ARGV' before you've tried to read from it might
give you the wrong answer. Not only that, you might not read from 'ARGV'.
If the value in '@ARGV' is the magic filename '-' (a convention to mean the
standard filehandle for input or output), 'ARGV' might actually be 'STDIN'.
You don't want to think about all of this. This module is discussed in
_Perl Best Practices_ on page 218. Also see the 'ARGV' entry in perlvar and
the 'readline' entry in perlfunc.
* '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
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.
