type Posflag ¶
type Posflag struct {
// contains filtered or unexported fields
}
Posflag implements a pflag command line provider.
func Provider ¶
Provider returns a commandline flags provider that returns a nested map[string]interface{} of environment variable where the nesting hierarchy of keys are defined by delim. For instance, the delim "." will convert the key `parent.child.key: 1` to `{parent: {child: {key: 1}}}`.
It takes an optional (but recommended) Koanf instance to see if the the flags defined have been set from other providers, for instance, a config file. If they are not, then the default values of the flags are merged. If they do exist, the flag values are not merged but only the values that have been explicitly set in the command line are merged.
func ProviderWithValue ¶ added in v0.16.0
func ProviderWithValue(f *pflag.FlagSet, delim string, ko *koanf.Koanf, cb func(key string, value string) (string, interface{})) *Posflag
ProviderWithValue works exactly the same as Provider except the callback takes a (key, value) with the variable name and value and allows their modification. This is useful for cases where complex types like slices separated by custom separators.
