NAME

no::warnings - suppress certain warnings for a dynamic scope

SYNOPSIS

Load the module:

use no::warnings;

Disable all warnings for a dynamic scope:

my $result = no::warnings sub {
  ...;
};

Disable specific warnings for a dynamic scope:

my $result = no::warnings qr/.../, qr/.../, sub {
  ...;
};

DESCRIPTION

This module provides a function called no::warnings which takes a coderef optionally preceded by a list of things to match.

If no list is provided, it will run the coderef, ignoring any warnings that would have otherwise been printed to STDERR, and returns the result of the coderef.

If a list of warnings to ignore is provided, it will run the coderef, ignoring any warnings that match the list (see match::simple), and returns the result of the coderef.

This differs from the standard no warnings pragma in that it acts dynamically instead of lexically, allowing you to suppress the printing of warnings which come from third-party modules, etc. Internally, it uses $SIG{__WARN__} but if you already have a handler for __WARN__, this module should be smart enough to work alongside it unless you're doing something especially odd.
