Is there a way to exclude packages from being profiled?

[jguluarte]

Hello,

I've looked through the documentation, and it seems that this package
is based on a few others. One of those is Devel::Profiler, and it has
a "bad_pkgs" that you can include that will cause it to ignore an
$array_ref list of packages from the profile output. I haven't seen
any way to invoke this through the current options, and wanted to see
if somebody else has already implemented in their own code or if it is
planned in a new release - or if it would be better to "hack" it in
myself.

It's not implemented. Why do you think this feature would be useful?

Quite an old topic, but one use case would be to prevent Catalyst/Moose/Class::MOP/etc. from cluttering flame graphs, "top 15 subs", etc.

I s'pose it's a modification to nytprofhtml as opposed to the actual profiler.

Meanwhile, it's pretty easy to create your own flame graph using "grep -v"
on the calls file to filter out packages you're not interested in.

It's basically

grep -v "Class::MOP" nytprof/all_stacks_by_time.calls | flamegraph.pl > test.svg

(though see nytprofhtml for details of extra args to scale values etc)
