NAME
Devel::Events::Filter::Warn - log every event to STDERR
VERSION
version 0.10
SYNOPSIS
# can be used as a handler
my $h = Devel::Events::Filter::Warn->new();
# or as a filter in a handler chain
my $f = Devel::Events::Filter::Warn->new(
handler => $sub_handler,
);
DESCRIPTION
This is a very simple debugging aid to see that your filter/handler chains are set up correctly.
A useful helper function you can define is something along the lines of:
sub _warn_events ($) {
my $handler = shift;
Devel::Events::Filter::Warn->new( handler => $handler );
}
and then prefix handlers which seem to not be getting their events with _warn_events
in the source code.
