Switon's PSR-3 logger for application services that want automatic categories, structured context, per-category filtering, and low-setup defaults.

Highlights
----------

[](#highlights)

- **Standard logger contract:** `LoggerInterface` is the main logging contract.
- **Automatic category routing:** log categories can be derived from the caller.
- **Structured context:** placeholder interpolation and extra context stay structured.
- **Output backends:** stdout, file, syslog, and memory sinks are available.
- **Category-aware filtering:** `Logger` derives categories from the caller and applies per-category levels.

Installation
------------

[](#installation)

```
composer require switon/log
```

Quick Start
-----------

[](#quick-start)

```
use Psr\Log\LoggerInterface;
use Switon\Core\Attribute\Autowired;

class UserService
{
    #[Autowired] protected LoggerInterface $logger;

    public function login(int $userId): void
    {
        $this->logger->info('User logged in', ['user_id' => $userId]);
    }
}
```
