Re: [Boston.pm] suppressing warnings
is there a way to suppress this warning from inside testpackage.pm somehow?
I've tried a bunch of things and still haven't found a solution.
Is this not possible to do in per?
Or is it so obvious I can't see it?
Greg
package file testpackage.pm:
package testpackage;
use warnings;
use strict;
use Data::Dumper;
use Exporter 'import';
our @EXPORT = qw ( somesub );
sub somesub{
my ($name)=@_;
my @caller=caller(0);
my $package=$caller[0];
my $evalstr = '$'.$package.'::'.$name.' = 42;';
eval($evalstr);
}
1;
script file testscript.pl:
#!/usr/bin/env perl
use warnings;
use strict;
use testpackage;
somesub('tricky');
print hello, tricky is '$main::tricky'\n;
When I run this script, I get the warning:
Name main::tricky used only once: possible typo at ./testscript.pl
is there a way to suppress this error from inside testpackage.pm somehow?

Re: [Boston.pm] suppressing warnings
You can add some no-op-ish noise to sidestep the warning e.g; local $main::tricky; or use vars '$main::tricky'; ___ Boston-pm mailing list Boston-pm@mail.pm.org http://mail.pm.org/mailman/listinfo/boston-pm

%SIG is global, so ...
$SIG{__WARN__} = sub {
my @args = @_;
# do whatever you want with the warning
}

Re: [Boston.pm] suppressing warnings
This pragma usage is lexically scoped, too.

Re: [Boston.pm] suppressing warnings
If your module has an import method, and in that method calls
warnings-unimport(once) then the unimport should be lexically
scoped to where your package was used. Which in the normal case is
the whole file, so it works.
