Functions

func ConcurrentAction

func ConcurrentAction(maxConcurrent uint, action func(interface{}) (interface{}, error)) (chan<- interface{}, <-chan ConcurentOutput)

ConcurrentAction create a pool of goroutines for executing action with concurrency limits (default to NumCPU)

func FirstLowerCase

func FirstLowerCase(s string) string

FirstLowerCase change first letter to lowerCase

func FirstUpperCase

func FirstUpperCase(s string) string

FirstUpperCase change first letter to UpperCase

func GetID

func GetID(r *http.Request) string

GetID return ID of URL (first section between two slashes)

func IncludesString

func IncludesString(array []string, lookup string) bool

IncludesString checks in an array includes given string

func IsRoot

func IsRoot(r *http.Request) bool

IsRoot checks if current path is root (empty or only trailing slash)

func LookupEnvBool

func LookupEnvBool(key string, defaultValue bool) bool

LookupEnvBool search for given key in environment as bool
