DEVICE AND METHOD FOR AIDING DEVELOPMENT OF APPLICATION GENERATOR

摘要

PROBLEM TO BE SOLVED: To improve the efficiency in the development of an application generator by making describable a program piece to be described in conversion rule definition to be the specifications of generator operation similarly to an output program piece to be outputted from a generator and making automatically generaable an abstract syntax tree data type definition expressing a syntax analyzer and generator input specifications from grammar specifications to be the generator operation specifications. SOLUTION: The application generator development aiding device 10 is provided with a means 101 for generating the data structure of a term analyzer, a syntax analyzer and an abstract syntax tree from a term analysis specification and a grammar specification to be the operation specifications of the generator and generating an input specification abstract syntax tree expressing the syntax analytical result of an input specification for regulating the operation specifications of a generator output program by using the data structure of the abstract syntax tree, a means 102 for converting output program piece description in conversion rule definition to be the operation specifications of the generator into a conversion rule and a means 103 for executing the abstract syntax tree of the input specification on the basis of the conversion rule outputted from the means 102 and outputting the execution result as a generator output program.
