Programming Language Translation Jamie McAtamney

Background Similar research Jazillian pay-per-program translation company Terekhov & Verhoef’s paper on translation difficulties Lili Qiu's paper on procedural vs. object-oriented languages Erik Demaine’s paper on pointers Todd Proebsting’s paper on Java to C translation Anonymous paper on structs

Methodology Translation algorithm Formatting  Remove programming idiosyncrasies Single-Pass translator  Handles syntax whose context is on the same line Two-Pass translator  Handles syntax whose context is elsewhere in the program Formatting  Makes everything look nice

Methodology Finished  Primitive types  Arrays  Method headers  Input/output  Preprocessor directives  Most package methods  Structs  Pointers Mostly Done Graphics Possible future topics Computer-to-computer communication

Methodology Testing & Analysis Testing old C programs  Have a few “fake” programs to test particular modules Script to do testing 4 th Quarter Results  Compilable and runnable  Pointers finished

Progress Results Thus Far Program is still error-free All implemented areas fully translated  Minus graphics, of course Translator outputs compilable and runnable program ~96% C syntax translatable

Sample Screenshots

Progress Analysis Finished exactly what I wanted to  Managed to get pointers done despite the research papers on the topic Where to go from here Might keep fiddling with it. Possibly revisit graphics if I can get JOGL working Maybe do MPI
