Devel::Events::Generator::LineTrace - generate executing_line
events using the perl debugger api.
my $g = Devel::Events::Generator::LineTrace->new( handler => $h ); $g->enable(); # every line of code will fire an event until $g->disable();
This Devel::Events generator will fire line tracing events using DB::DB
, a perl debugger hook.
Only one instance may be enabled at a given time. Use Devel::Events::Handler::Multiplex to deliver events to multiple handlers.
When the generator is enabled, this event will fire for every line of code just before it is executed.
Lines in a package starting with Devel::Events::
will not be reported.
Enable this generator instance, disabling any other instance of Devel::Events::Generator::LineTrace.
Stop firing events.
Called by DB::DB
. Used to generate the event.
Apparently this must be run under perl -d
. This is very strange, since Devel::Events::Generator::SubTrace doesn't need the -d
flag set.
The Enbugger module can help overcome this limitation.
