fmt.Println(bbg.Parse("[b]Hello World[/b]"))

// Output:
// <b>Hello World</b>

Adding Custom Tags

bbg.RegisterTag("color", bbgo.Processor(func(ctx *context.Context, tag node.Tag, w io.Writer) {
    switch t := tag.(type) {
	case *node.OpeningTag:
        // write here logic for opening tag
    case *node.ClosingTag:
        // write here logic for opening tag
    case *node.SelfClosingTag:
        // write here logic for self-closing tag
	}
}))

The default tags can also be modified by calling bbg.RegisterTag:
