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
