MVC (model view controller) mode-based language transformation method and equipment for program

The invention aims to provide an MVC (model view controller) mode-based language transformation method and equipment for a program. The transformation equipment, after determining the initial programming language adopted by the to-be-transformed initial program, analyses encoding structure of initial program according to an MVC mode so as to determine the transformation content and non-transformation content during encoding, language transformation is performed on the transformation content according to the target programming language by combining the transformation content, so as to generate one or more target encoding files, and frame transformation is finally performed on the non-transformation content and the target encoding file so as to generate a target program corresponding to the initial program. Compared with the prior art, the MVC (model view controller) mode-based language transformation method and equipment for the program can support the transformation among a plurality of languages, and support continuous increasing of language and frame editions; the expansibility is better; by adopting the method and equipment, the program transformation efficiency is improved, and the development time and resource consumption are reduced.
