Or any other older version, I'm sure. All commandline related stuff is in luainit.w, I think.

I probably need to svn up, because I can only find luainit.c, no luainit.w.

And now I suddenly see what is going wrong: your backslash is intercepted by the code that looks for "luatex \\relax ...".

OK, you will probably know how to fix this better than I do (still can't find that in the code).

Should be fixed by #3621 (in branches/0.60.x/, so far) please try it out.

Thanks, I'll try to try and report back (I need to checkout the branch first).

Another question (two actually). In ex_selfdir function in luainit.c you derive derive the directory of the executable from argv[0] using SearchPath(). Is this intended (argv[0] might not correspond to the actual executable) or are you actually after the real path of the executable (in which case GetModuleFileName() should be used)?

This is most probably on purpose. I inherited the current code from kpathsea, and I think it makes sense to do what kpathsea does in case someone wants to replace kpathsea by lua code (like Hans does).

From the kpse source it looks like a workaround for some win95 issues. Better leave it like that

...

The second question is what is this path used used for?  It is exposed on the Lua side through os.selfdir, but this is not documented, so I wonder if one can rely on it or if it is some internal thing.

os.selfdir should have been documented already, it has slipped through the cracks somehow. I'll fix the manual.

Thanks, Tomek
