Instance Method Details

#cameltoeize(string, inverse_mode = false) ⇒ Object

By default, cameltoeize converts strings to CameLtoEcasE. If the argument to camelize is set to “:inverse” then camelize produces iNVERSECaMeLTOECASe.

Examples

cameltoeize("Lindsay Lohan") #=> "LindSayLohaN"
cameltoeize("Jessica Simpson") #=> "JessiCasImpsoN"
cameltoeize("Britney Spears", :inverse) #=> "bRITNeYsPEARs"
cameltoeize("Anna Kournikova", :inverse) #=> "aNNAKoURnIKOVa"
