Functions

func GetBoolEnvVar

func GetBoolEnvVar(key string) bool

GetBoolEnvVar reads an environment variable and returns the value as a bool, if the environment variable is not set then the application will panic.

func GetEnvVar

func GetEnvVar(key string) string

GetEnvVar reads an environment variable and returns the value as a string, if the environment variable is not set then the application will panic.

func GetIntEnvVar

func GetIntEnvVar(key string) int

GetIntEnvVar reads an environment variable and returns the value as an int, if the environment variable is not set then the application will panic.

func GetOptionalBoolEnvVar

func GetOptionalBoolEnvVar(key string, def bool) bool

GetOptionalBoolEnvVar reads an environment variable and returns the value as a bool, or the default value if the environment variable is not set. If the environment variable is set but cannot be parsed as a bool then the application will panic.

func GetOptionalEnvVar

func GetOptionalEnvVar(key string, def string) string

GetOptionalEnvVar reads an environment variable and returns the value as a string, or the default value if the environment variable is not set.

func GetOptionalFloatEnvVar

func GetOptionalFloatEnvVar(key string, def float64) float64

GetOptionalFloatEnvVar reads an environment variable and returns the value as a float64, if the environment variable is not set then the application will panic. If the environment variable is set but cannot be parsed as a float64 then the application will panic.

func GetOptionalIntEnvVar

func GetOptionalIntEnvVar(key string, def int) int

GetOptionalIntEnvVar reads an environment variable and returns the value as an int, or the default value if the environment variable is not set. If the environment variable is set but cannot be parsed as an int then the application will panic.
