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!\n" while 1;
}
{
  # ...or an object interface
  my $token = new IO::Pager::Unbuffered;
  $token->print("OO shiny...\n") while 1;
}
            
          

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 {
  local $SIG{PIPE} = sub { die };
  local $STDOUT = IO::Pager::open(*STDOUT);
  while (1) {
    # Do something
  }
}
# Do something else
