in reply to Split string after 14 Line Feeds?

A more general approach with "nested" iterators:

sub read_chunk { my ($fh,$mod) = @_; my $chunk; while ( <$fh> ) { $chunk .= $_; return $chunk unless $. % $mod; } return $chunk; } open my $fh, "<", \$string; while ( my $chunk = read_chunk( $fh, 14 ) ) { print $chunk; print "-"x5,"\n"; }

works with anything you can open via filehandle even strings.

[arc444]: hi. Anyone know how to filter the list of methods returned when querying an object in the perl debugger ?
[arc444]: for example : m $obj | grep 'blah'
