func (*Formatter) Color ¶

func (formatter *Formatter) Color(text string) string

Color wraps the given text in ANSI color escapes appropriate to the event's level. Error and higher are red. Warning is yellow. Notice and lower are cyan.

func (*Formatter) Fields ¶

func (formatter *Formatter) Fields() map[string]interface{}

Fields returns a map of the event's fields in single-level dot key notation. If the event's fields contain nested data, the nested data is flattened into a single level, with the previously nested levels added as keys prefixed with the parent's level, and a dot ('.').

Will convert to `foo.bar=baz`
