Abstract

A method, system and program product for transforming a source code in one language into one or more target modules in one or more languages is provided. The method includes selecting one or more target programming languages suitable for transforming each source module of a source code into one or more target modules written in one or more target programming languages. The method further includes parsing the source code and looking up for a source function in the source code an equivalent target function in a target programming language, such that execution of the equivalent target function in the target programming language is optimized. The method further includes writing out in the target programming language the equivalent target function corresponding to the source function, such that each source module is transformed into one or more target modules whose execution in the one or more target programming languages is optimized.
