Functions

func MapIterator

func MapIterator(data []interface{}) (func() bool, func() Map)

func StrIterator

func StrIterator(data []interface{}) (func() bool, func() string)

Types

type Changes

type Changes map[string]changeItem

type Map

type Map map[string]interface{}

func (Map) Compare

func (old Map) Compare(new Map) Changes

Compare compares `new` and `old` and returns a mapping of changed, added, or removed items.

func (Map) Delete

func (m Map) Delete(key string)

func (Map) DeleteSpecial

func (m Map) DeleteSpecial(prefix string)

func (Map) GetIntDef

func (m Map) GetIntDef(key string, def int) int

func (Map) GetList

func (m Map) GetList(key string) []interface{}

func (Map) GetMap

func (m Map) GetMap(key string) Map

func (Map) GetStr

func (m Map) GetStr(key string) string

func (Map) GetStrDef

func (m Map) GetStrDef(key, def string) string

func (Map) GetStrDefGlob

func (m Map) GetStrDefGlob(key, def string) string

GetStrDefGlob: If key not found return default. If found expand global variable reference ($$...$$) in value.

func (Map) GetStrDefGlob1

func (m Map) GetStrDefGlob1(key, def string) string

GetStrDefGlob1: If key not found try to look it up in global vars. If found expand global variable reference in value.

func (Map) GetStrDefGlob2

func (m Map) GetStrDefGlob2(key, keyglob, def string) string

GetStrDefGlob2: If key not found try to look it up in global vars using the special key given as second parameter. If found expand global variable reference in value.

func (Map) GetStrList

func (m Map) GetStrList(key string) (r []string)

func (Map) IterateMap

func (m Map) IterateMap(key string, fct func(Map))

func (Map) IterateMapDef

func (m Map) IterateMapDef(key string, def Map, fct func(Map))

func (Map) IterateStr

func (m Map) IterateStr(key string, fct func(string))

type Vars

type Vars interface {
	Get(string) (string, bool)
	Set(string, string)
}

var GlobalVars Vars = VarsMap{}

type VarsMap
