func FlagErr ¶

func FlagErr(flagName, format string, a ...any) error

func GetParamByName ¶

func GetParamByName(paramName, paramsStr string) (string, error)

func Map ¶

func Map(flagName, paramsStr string, obj interface{}) error

Map assigns the parameter value into the right struct field, which is represented by obj. For example, if we use Map("param1", "value1", &myFlag) with MyFlag struct above, Param1 field would be assigned with "value1". Note that this function may modify the passed in object, even if an error is returned. The reason for this is that we don't know the type of the passed in object and if there is a copy function for it. It is up to the caller to create a copy of the passed in object if required.

func SplitPrefixedName ¶

func SplitPrefixedName(prefixedName string) (string, string, error)

SplitPrefixedName splits prefixedName with "/" as a separator

func Supported ¶

func Supported(obj interface{}) string

Supported returns the list of supported flags for a parameter struct. This is mainly used to show the user the list of supported parameters
