Functions

func ConvertECALToJSONObject

func ConvertECALToJSONObject(v interface{}) interface{}

ConvertECALToJSONObject converts an ECAL container structure into an object which can be marshalled into a JSON string.

func ConvertJSONToECALObject

func ConvertJSONToECALObject(v interface{}) interface{}

ConvertJSONToECALObject converts a JSON container structure into an object which can be used by ECAL.

func EvalToString

func EvalToString(v interface{}) string

EvalToString should be used if a value should be converted into a string.

func NameFromASTNode

func NameFromASTNode(node *parser.ASTNode) string

NameFromASTNode returns a scope name from a given ASTNode.

func NewScope

func NewScope(name string) parser.Scope

NewScope creates a new variable scope.

func NewScopeWithParent

func NewScopeWithParent(name string, parent parser.Scope) parser.Scope

NewScopeWithParent creates a new variable scope with a parent. This can be used to create scope structures without children links.

func SetParentOfScope

func SetParentOfScope(scope parser.Scope, parent parser.Scope)

SetParentOfScope sets the parent of a given scope. This assumes that the given scope is a varsScope.

func ToObject

func ToObject(vs parser.Scope) map[interface{}]interface{}

ToObject converts a Scope into an object.

func ToScope

func ToScope(name string, o map[interface{}]interface{}) parser.Scope

ToScope converts a given object into a Scope.
