func Flatten ¶

func Flatten(thing map[string]interface{}) (map[string]string, error)

Flatten takes a structure and turns into a flat map[string]string.

Within the "thing" parameter, only primitive values are allowed. Structs are not supported. Therefore, it can only be slices, maps, primitives, and any combination of those together.

See the tests for examples of what inputs are turned into.

func FormatAsTable(entries []string, header string) (string, error)

FormatAsTable formats the given string entries as table where the header string defines the column titles.
