IO::Pager::Unbuffered(3) 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!\n";
}
{
# ...or an object interface
my $token = new IO::Pager::Unbuffered;
$token->print("OO shiny...\n");
}

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
