const (

Functions ¶

func GetLogLevel ¶ added in v0.12.1

func GetLogLevel() string

GetLogLevel reads LOG_LEVEL, falling back to dev when unset or unknown. A set-but-unknown value warns so the misconfiguration is not silent.

Types ¶

type Map ¶

type Map map[string]*Var

Map is a map of environment variables. We use a *Var as map values are not addressable, i.e. cannot be modified directly.

func (Map) SetEnv ¶

func (m Map) SetEnv() error

SetEnv reads and sets the provided list of env vars based on the Map.

type Var ¶

type Var struct {
	Value        string
	DefaultValue string
	IsInteger    bool
	IntValue     int
	IsBoolean    bool
	BooleanValue bool
	OneOf        []string
	Optional     bool // controls whether an env variable can be missing from the .env file but still declared
}

Var describes an environment variable and its configuration.

func NewLogLevelVar ¶ added in v0.16.0

func NewLogLevelVar() *Var

NewLogLevelVar returns the canonical LOG_LEVEL variable: defaults to dev. Deliberately not constrained via OneOf: an unknown value must not fail startup — consumers normalize it through GetLogLevel (warn + dev fallback), matching pre-OTel releases. Fresh *Var per call so Maps don't alias it.
