Hi, I saw in another post that loading of binary modules has been enabled in luatex (great!) that requires a stock lua51.dll on Windows. I wonder if this side-effect that will last or pass? I'm in the process of rewriting the generic script wrapper for TL on Windows to replace the current batch script(s). I didn't want to code everything in C, so I use only a thin binary stub that links with luatex.dll, sets up the argument list and calls dllluatexmain with 'texlua' and a predefined script as argv[0] and argv[1]. This is nice as I can implement most of the logic on the lua side but there is currently no elegant way to return to the C side (luatex exits rather than return) nor I can easily pass some data back. This is not a big problem for me ATM (after finding a workaround for os.spawn I don't need to return to the C side) but it could be useful in general to have more open access to (tex)lua interpreter from C. Is anything along these lines on the agenda? Cheers, Tomek
