NAME

Require::HookChain::log::logger - Log a message to Log::ger

VERSION

This document describes version 0.006 of Require::HookChain::log::logger (from Perl distribution Require-HookChain), released on 2023-02-07.

SYNOPSIS

use Require::HookChain 'log::ger';
# now each time we require(), a logging statement is produced at the trace level

A demo (nauniq is a Perl script you can get from CPAN, and Log::ger::Screen is a module to show log statements on the terminal. Note that the loading of strict.pm and warnings.pm are not logged because they are already loaded by Log::ger::Screen. If you want logging of such modules you can try Require::HookChain::log::stderr which avoids the use of any module itself.

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.
