Functions

func DefaultValue 

func DefaultValue(name string) (string, bool)

DefaultValue looks up the default value

func Name 

func Name(field string) string

Name gets the environment variable Name for a config schema field

func TryName 

func TryName(field string) string

TryName gracefully tries to get the environment variable Name for a config schema field

func ZeroValue 

func ZeroValue(name string) interface{}

ZeroValue returns the zero value for a named field, or panics if it does not exist.

ConfigSchema records the schema of configuration at the type level

type EnvVar 

type EnvVar struct {
	// contains filtered or unexported fields
}

EnvVar is an environment variable which

func New 

func New(name string, parse func(string) (interface{}, error)) *EnvVar

New creates a new EnvVar for the given name and parse func. name must match the ConfigSchema field.

func (*EnvVar) Parse 

func (e *EnvVar) Parse() (v interface{}, invalid string)

Parse attempts to parse the value returned from the environment, falling back to the default value when empty or invalid.

func (*EnvVar) ParseBool 

func (e *EnvVar) ParseBool() (v bool, invalid string)

ParseBool parses bool

func (*EnvVar) ParseFrom 

func (e *EnvVar) ParseFrom(get func(string) string) (v interface{}, invalid string, err error)

ParseFrom attempts to parse the value returned from calling get with the env var name, falling back to the default value when empty or invalid.

func (*EnvVar) ParseLogLevel 

func (e *EnvVar) ParseLogLevel() (v zapcore.Level, invalid string)

ParseLogLevel parses an env var's log level

func (*EnvVar) ParseString 

func (e *EnvVar) ParseString() (v string, invalid string)
