# simple-log

`simple-log` is a small convenience layer on top of Racket's logging system.
It provides generated procedures for the standard log levels and supports
logging to the display, a file, custom callbacks, and a filterable in-memory
store.

```racket
#lang racket

(require simple-log)

(sl-def-log example)
(define logs (sl-log-to-store 1000))
(sl-log-to-display)

(info-example "Started with ~a items" 3)
(warn-example "An example warning")
(sync-log-example)

(sl-store->display
 (sl-store-grep-level logs 'warning))
```

Topic filters can select multiple topics or invert a match:

```racket
(sl-store-grep-topic logs '(webview webview-backend))
(sl-store-grep-topic logs 'webview-backend #:invert? #t)
```

The Scribble manual documents logger definitions, destinations, log levels,
synchronization, and all in-memory store operations.
