| Research Abstract |
Construction of software development enviroment based on attribute grammar formalisms has been studied. Originally, attribute grammarhas been invented for describing formal semantics of programminglanguages and much amount of work has been preformed to automatecompiler construction. The principle of attribute grammar is, however, computation of values on trees and it is very general andfundamental computational, model which is useful not only for language processing but also for software developmet when tree structures of hierarchical structures play essential role. In our project, we have done three works on the construction of software development environment based on the attribute grammar formalisms.
The first work is on a hierarchacal and fuctional programming language AG and its environment. AG is a language based on the priniciple of hierarchical decomposition of functions and derived from attribute grammar formalism. Programming environment SAGE for AG has been constructed which consists of structure editor, interpreter, debugger, browser, compiler and verifier.
The second work is to model software development process in the hierarchical and function software process model HFSP and enact the process on the SAGE system. Properties of HFSP and enaction mechanism for HFSP has been studied together with enation of JSD and JSD process on SAGE.
The third part of oru results is the proposal of an objective attribute grammar OAG and its application to the description of software objects. OAG is obtained from the usual attribute grammar by adding state and reflective mechanism and formulated in the framework of object-oriented programming. Evaluation mechanism for OAG and its application to software objectbase have been studied.
