DESCRIPTION

This hook should be put at the beginning to be able to log before other hooks or source loads the module, so it's best to require this hook last, e.g.:

use Require::HookChain 'other::hook';
use Require::HookChain 'other::hook2';
...
use Require::HookChain 'log::stderr';

or:

use Require::HookChain 'log::stderr';
use Require::HookChain -end=>1, 'other::hook';
use Require::HookChain -end=>1, 'other::hook2';
...

CONTRIBUTING

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:

% prove -l

If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.
