NAME

       IO::Pager::Unbuffered - Pipe output to PAGER if destination is a TTY

SYNOPSIS

	 use IO::Pager::Unbuffered;
	 {
	   local $STDOUT = IO::Pager::Unbuffered::open *STDOUT;
	   print <<"  HEREDOC" ;
	   ...
	   A bunch of text later
	   HEREDOC
	 }

	 {
	   # You can also use scalar filehandles...
	   my $token = IO::Pager::Unbuffered::open($FH) or warn($!);
	   print $FH "No globs or barewords for us thanks!
";
	 }

	 {
	   # ...or an object interface
	   my $token = new IO::Pager::Unbuffered;

	   $token->print("OO shiny...
");
	 }

DESCRIPTION

       IO::Pager subclasses are designed to programmatically decide whether or not to pipe a filehandle's output to a program specified in PAGER;
       determined and set by IO::Pager at runtime if not yet defined.

       See IO::Pager for method details.

METHODS

       All methods are inherited from IO::Pager; except for instantiation.

CAVEATS

       You probably want to do something with SIGPIPE eg;

	 eval {
	   $SIG{PIPE} = sub { die };
	   local $STDOUT = IO::Pager::open(*STDOUT);

	   while (1) {
	     # Do something
	   }
	 }

	 # Do something else
