Does your debugger utilize debug.getinfo and debug.traceback? If so, could you replace those functions at run-time with ones that remap the file names? It may go roughly like this: local old_getinfo = debug.getinfo function debug.getinfo(...) ........ local t = old_getinfo(........) if t.source:match'^@.*%.preprocessed$' then <read source file or byte code with specially encoded source/line info in comments or debug info> t.source = translated_source t.currentline = translated_line ...... end ........ return t end
