Functions

func Lookup

func Lookup(i interface{}, path ...string) (reflect.Value, error)

Lookup performs a lookup into a value, using a path of keys. The key should match with a Field or a MapIndex. For slice you can use the syntax key[index] to access a specific index. If one key owns to a slice and an index is not specificied the rest of the path will be apllied to evaley value of the slice, and the value will be merged into a slice.

func LookupI

func LookupI(i interface{}, path ...string) (reflect.Value, error)

LookupI is the same as Lookup, but the path keys are not case sensitive.

func LookupString

func LookupString(i interface{}, path string) (reflect.Value, error)

LookupString performs a lookup into a value, using a string. Same as `Lookup` but using a string with the keys separated by `.`

func LookupStringI

func LookupStringI(i interface{}, path string) (reflect.Value, error)

LookupStringI is the same as LookupString, but the path is not case sensitive.

func SplitNameByWords

func SplitNameByWords(src string) []string
