CHAPTER 8. SPECIFICATIONS RSL specification: ValueExpr == Make_ValueOrVariableName( value_or_variable_name : ValueOrVariableName) | ProductExpr(value_expr_list : ValueExpr ∗ ) | ValueInfixExpr( left : ValueExpr, op : InfixOperator, right : ValueExpr), ValueOrVariableName :: id : Id, InfixOperator == PLUS | MINUS | EQUAL, Id :: getText : Text As can be seen in Example 8.1 the parenthesizes and commas of the product expression are removed in the RSL AST specification. 8.3 Specification of the Transformer The specification of the transformer Transformer.rsl described in this section is written in RSL. It specifies how an applicative version of an RSL AST can be transformed into the corresponding imperative version of the RSL AST. The full specification of the transformer in RSL can be found in Appendix C. In the following a description of four maps central to the transformer specification will be given and then the structure of the specification will be described. 8.3.1 The Maps In order to do the transformation some extra types are necessary. These extra types are described in the following. The TRANS Map The map TRANS is defined as follows: TRANS = Id →m Id 74
8.3. SPECIFICATION OF THE TRANSFORMER The TRANS map maps each type of interest to the corresponding variable name. This map is established from the user input and is used both during the check for transformability and during the transformation phase in order to figure out what the type names of the types of interest are and in order to do proper variable replacements. The TYPINGS Map The map TYPINGS is defined as follows: TYPINGS = Id →m Id ∗ The TYPINGS map maps type name identifiers to the list of type identifiers obtained by recursively expanding the right hand side of the type definitions. This means that the type definition: results in the TYPINGS map: A = B × C, B = D, C = A, D = Int TYPINGS = [ A ↦→ 〈B, C, D, A〉, B ↦→ 〈D〉, C ↦→ 〈A, B, C, D〉, D ↦→ 〈〉 ] The TYPINGS map is used to check that types of interests are not recursively defined and that they are not part of sets, lists and maps. The RSL type checker only checks that types are not recursively defined through abbreviation type definitions, while recursion through union, short record and variant type definitions is allowed. For example, a type definition of the form: Elem, Collection == empty | add(Elem, Collection) is allowed in RSL but not allowed when using the transformer. The value of the TYPINGS map is computed in the beginning of the transformation in the function TRClassExpr and this value is not altered during the transformation. 75
