(dv) 9 great CPAN modules released last week
Updates for great CPAN modules released last week. A module is considered great if its favorites count is greater or equal than 12. CPA...niceperl.blogspot.com
As you may know, the release of a new version of Perl triggers the process to elect a new Perl Steering Council. That process has been taking place over the last few weeks and the results were announced a few days ago.
Congratulations to returning members Philip Bruhat and Graham Knop and to new member Aristotle Pagaltzis. And many thanks to retiring member Paul Evans.

An analyzer has been implemented for the Perl track on exercism.org. Currently it uses Perl::Critic to give feedback when a user submits an implementation of an exercise.
The list of policies in use is quite lean at the moment, but hopefully the feedback should prove useful to newbies getting to grips with Perl!

I'm using h2xs to make glue code for a C library to a module. Imagine this scenario in the C header:
struct foo; struct foo * new_foo(); void set_foo_member(struct foo * f, int value); int get_foo_member(const struct foo * f); When I run
h2xs -x on this I get something like this in the .xs file:struct foo * new_foo() int get_foo_member(f) const struct foo * f void set_foo_member(f, value) struct foo * f int value and in the
typemap:const struct foo * T_PTROBJ struct foo * T_PTROBJ This builds fine, however, when I go to actually use the code like this:
my $foo = new_foo(); $foo->set_foo_member(123); print "Foo member is: " . $foo->get_foo_member(); I get an error like the following:
get_foo_member: Expected f to be of type const struct FooPtr; got struct FooPtr=SCALAR(0x2ecd9c2dd768) instead at ... Right, so, that's the backstory. XS checks the type of incoming objects and makes sure they match the expected type from the C header, and if they differ, it throws an error. But it seems to be considering
struct foo * and const struct foo * to be two different types, even though they're not (really). Perl shouldn't care about this at all.What's the solution here? Do I remove all const keywords in my XS code? Is there some switch or setting to make xsubpp treat both as the same type? Something else?

I have a Perl script that takes several hours to run, I need to know when it's done, but I sometimes forget to keep checking.
It's running on Strawberry in Windows Server 2019. How easy would it be to write another script to send an email? I could run them as a batch I'm thinking.
I'm very weak at programming, I really only dabble.
