IO::Pager::Page - Emulate IO::Page, pipe STDOUT to a pager if STDOUT is a TTY

Pipes STDOUT to a pager if STDOUT is a TTY

IO::Pager was designed to programmatically decide whether or not to point the STDOUT file handle into a pipe to program specified in the PAGER environment variable or one of a standard list of pagers.

  BEGIN {
    use IO::Pager::Page;
    # use I::P::P first, just in case another module sends output to STDOUT
  }
  print<<HEREDOC;
  ...
  A bunch of text later
  HEREDOC

If you wish to forgo the potential for a Broken Pipe foible resulting from the user exiting the pager prematurely, load IO::Pager::Page like so:

  use IO::Pager::Page hush=>1;

IO::Page, IO::Pager, IO::Pager::Unbuffered, IO::Pager::Buffered
