# ABSTRACT: (DEPRECATED)(ADOPTME) Send Log::Any logs to a subroutine
__END__

=head1 NAME
Log::Any::Adapter::Callback - (DEPRECATED)(ADOPTME) Send Log::Any logs to a subroutine
=head1 VERSION
This document describes version 0.102 of Log::Any::Adapter::Callback (from Perl distribution Log-Any-Adapter-Callback), released on 2023-11-21.
=head1 SYNOPSIS
# say, let's POST each log message to an HTTP API server
use LWP::UserAgent;
my $ua = LWP::UserAgent->new;
use Log::Any::Adapter;
Log::Any::Adapter->set('Callback',
min_level => 'warn',
logging_cb => sub {
my ($method, $self, $format, @params) = @_;
$ua->post("https://localdomain/log", level=>$method, Content=>$format);
sleep 1; # don't overload the server
},
detection_cb => sub { ... }, # optional, default is: sub { 1 }
);
=head1 DESCRIPTION
DEPRECATION NOTICE: Log::Any distribution since 1.708 comes with
L<Log::Any::Adapter::Capture> which does the same thing. I'm deprecating this
adapter now.
This adapter lets you specify callback subroutine to be called by L<Log::Any>'s
logging methods (like $log->debug(), $log->error(), etc) and detection methods
(like $log->is_warning(), $log->is_fatal(), etc.).
This adapter is used for customized logging, and is mostly a convenient
construct to save a few lines of code. You could achieve the same effect by
creating a full Log::Any adapter class.
Your logging callback subroutine will be called with these arguments:
($method, $self, $format, @params)
where $method is the name of method (like "debug") and ($self, $format, @params)
are given by Log::Any.

=head1 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 L<Dist::Zilla>,
L<Dist::Zilla::PluginBundle::Author::PERLANCAR>,
L<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.

=head1 BUGS
Please report any bugs or feature requests on the bugtracker website L<https://rt.cpan.org/Public/Dist/Display.html?Name=Log-Any-Adapter-Callback>
When submitting a bug or request, please include a test-file or a
patch to an existing test-file that illustrates the bug or desired
feature.
