I'm trying to get this bit of code to work with the lua.c32 interpreter:
--- sample, the goal is to build a script that will allow me to enter a 4digit
mt and load the bios iso accordingly
print ("enter machine type :")
mt = io.read()
print ("you entered...",mt)
doStuff()
if (mt == "8141") then
syslinux.run_command("memdisk initrd=/dos/BIOS/FSC-P7935-108.img
raw")
end
--- the problem is that lua kicks out an error every time "...attempt to
call
field 'read' ( a nil value)"
--- this seems to work on the interpreter i installed on my linux box, but when
i use it as a com32 it fails.
--- boot: Lua.c32 /test/test.lua ---> runs lua script but fails on io.read()
any help appreciated
Thanks,

I wonder if we simply fail to hook up the console APIs, or if we totally failed to bind io.read() at all; which seems odd... -hpa
Is there a way for me to re-compile the "Lua.c32" to include the "io.read()" function for my testing? I'm kinda new and have looked through the docs+ threads but, my "Makefile" doesn't recreate the "Lua.c32" I'm definately willing to give it a try. I've noticed that "read" error is on any of the scripts in the "lua/test/.." folder that contain the io.read() or io.input() functions... Regards, EH
I think the issue may be in "/lua/src/liolib.c" I saw a lot of
commented out
io_read and other read related functions. I'm guessing they weren't
working
properly.
