# Log::Any::Adapter::Callback(3pm)

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

## NAME

Log::Any::Adapter::Callback - (DEPRECATED)(ADOPTME) Send Log::Any logs to a subroutine

## VERSION

This document describes version 0.102 of Log::Any::Adapter::Callback (from Perl distribution Log-Any-Adapter-Callback), released on 2023-11-21.

## 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 }
 );
```

## DESCRIPTION

DEPRECATION NOTICE: Log::Any distribution since 1.708 comes with 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 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.

## 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.
