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

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

IO::Pager is designed to programmaticly decide whether or not to point the STDOUT file handle into a pipe to program specified in $ENV{PAGER} or one of a standard list of pagers.

Instantiate a new IO::Pager to paginate FILEHANDLE if necessary. Assign the return value to a scoped variable.

FILEHANDLE

Defaults to currently select()-ed FILEHANDLE.

An alias for new.

Explicitly close the filehandle, if a pager was deemed necessary this will kill it. Normally you'd just wait for the user to exit the pager and the object to pass out of scope.

This does not default to the current filehandle.

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
