SYNOPSIS

9         use IO::Pager::Unbuffered;
10         {
11           local $STDOUT = IO::Pager::Unbuffered::open *STDOUT;
12           print <<"  HEREDOC" ;
13           ...
14           A bunch of text later
15           HEREDOC
16         }
17
18         {
19           # You can also use scalar filehandles...
20           my $token = IO::Pager::Unbuffered::open($FH) or warn($!);
21           print $FH "No globs or barewords for us thanks!\n" while 1;
22         }
23
24         {
25           # ...or an object interface
26           my $token = new IO::Pager::Unbuffered;
27
28           $token->print("OO shiny...\n") while 1;
29         }

DESCRIPTION

32       IO::Pager subclasses are designed to programmatically decide whether or
33       not to pipe a filehandle's output to a program specified in PAGER;
34       determined and set by IO::Pager at runtime if not yet defined.
35
36       See IO::Pager for method details.

METHODS

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

CAVEATS

42       You probably want to do something with SIGPIPE eg;
43
44         eval {
45           local $SIG{PIPE} = sub { die };
46           local $STDOUT = IO::Pager::open(*STDOUT);
47
48           while (1) {
49             # Do something
50           }
51         }
52
53         # Do something else
