+# Logging

 Simple logging module, that supports terminal coloring and different plugins

+```javascript
+const Logging = require("@hibas123/logging").default;
 
 Logging.log("Hello there");

 ```
 
 There are different Logging levels, that also apply terminal coloring:
 
-``` javascript
-Logging.debug("Debug message")
-Logging.log("Log message")
-Logging.warning("Warning")
-Logging.error(new Error("To less creativity"))
-Logging.error("Just an simple message as error")
-Logging.errorMessage("Nearly the same as error")
+```javascript
+Logging.debug("Debug message");
+Logging.log("Log message");
+Logging.warning("Warning");
+Logging.error(new Error("To less creativity"));
+Logging.error("Just an simple message as error");
+Logging.errorMessage("Nearly the same as error");
 ```
 
 All Logging types except the simple error take as many arguments as you want. These will be joined with spaces and serialized with the node util.inspect function.

 This logging module doesn't require any setup per default, but sometimes it makes sense to configure a few things.

 There is a Plugin API available, that makes is possible to add custom Logging Adapter.
 
-``` javascript
+```javascript
 const Demo = new LoggingBase("Demo");
 Demo.addAdapter(new DemoAdapter({ color: "rainbow" }));
 ```
 
 The adapters need to provide a very simple Interface:
 
-``` typescript
+```typescript
 interface Adapter {
-    init(observable: ObservableInterface<Message>, name?: string): void | Promise<void>;
+   init(): void | Promise<void>;
 
-    flush(sync: true): void;
-    flush(sync: false): void | Promise<void>;
+   onMessage(message: Message): void;
+
+   flush(sync: true): void;
+   flush(sync: false): void | Promise<void>;
 }
 
 interface Message {
-    type: LoggingTypes;
-    name?:string;
-    text: {
-    	raw: string[],
-    	formatted: string[]
-    };
-    date: Date;
-    file: string;
+   type: LoggingTypes;
+   names?: string[];
+   text: IFormatted;
+   date: Date;
+   file: string;
+}
+
+export interface IFormatted {
+   color?: IColors;
+   bgcolor?: IColors;
+   bold?: boolean;
+   italic?: boolean;
+   blink?: boolean;

 }
 
 enum LoggingTypes {
    Log,
    Warning,
    Error,
-   Debug
+   Debug,
 }
 ```
 
-The `ObservableInterface` comes from `@hibas123/utils`. It provides a very simple api for subscribing and unsubscribing from the message events.
