Programming Language Translation

• Jamie McAtamney

Background

• Similar research
• Jazillian pay-per-program translation company
• Terekhov Verhoefs paper on translation
  difficulties
• Lili Qiu's paper on procedural vs.
  object-oriented languages
• Erik Demaines paper on pointers
• Todd Proebstings 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

4
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

5
Methodology

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

6
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

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
