Types

type FieldTransformer

type FieldTransformer = func(field reflect.StructField) (interface{}, error)

FieldTransformer extract data type from struct field

type PathFlag

type PathFlag struct {
	// path flag mode
	RemainArgs []string
	// contains filtered or unexported fields
}

PathFlag will use path flag to specify config file and dot path

func NewPathFlag

func NewPathFlag(args []string) *PathFlag

NewPathFlag new PathFlag

func (*PathFlag) Flags

func (f *PathFlag) Flags() *pflag.FlagSet

Flags return flags of PathFlag

func (*PathFlag) Parse

func (f *PathFlag) Parse() error

Parse do flag parse

type TagParser

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

TagParser parse field tag string input like `posval,key1=val1,key2=val2`

func NewTagParser

func NewTagParser(tag string) (*TagParser, error)

NewTagParser make TagParser

func (*TagParser) QueryByKey

func (t *TagParser) QueryByKey(key string) string

QueryByKey query value by key

func (*TagParser) QueryByPos

func (t *TagParser) QueryByPos(pos int) string

QueryByPos query value by pos
