IO::Pager::Unbuffered(User Contributed Perl DocumentatIO::Pager::Unbuffered(3)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
