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"; } { # ...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
