NAME ^

Sig::PackageScoped - Make $SIG{__DIE__} and $SIG{__WARN__} package scoped

SYNOPSIS ^

  use Sig::PackageScoped qw(set_sig unset_sig);

  set_sig( __DIE__ => sub { die "Really dead: @_" } );

  unset_sig( __DIE__ => 1 );

DESCRIPTION ^

If all your modules use this module's functions to declare their signal handlers, then they won't overwrite each other. If you're working with modules that don't play nice, see Sig::PackageScoped::Paranoid. But really, this is more of a demonstration of weird things you can do with Perl than a good thing to use in production. You have been warned.

EXPORTS ^

This module will optionally export the set_sig and <unset_sig> subroutines. By default, nothing is exported.

FUNCTIONS ^

This module provides the following functions:

set_sig()

This function accepts a hash of options. The keys can be either __DIE__ or __WARN__, and the values should be coderefs to handle the specified pseudo-signal.

unset_sig()

This function also expects a hash. The keys should be the pseudo-signal to unset, and the value can be any true value.
