Lua require function

[cortomaltese_mf]

Hello there,
I use Lua script language, either calling lua scripts from C++ or calling C/C++ functions from lua. Im running lua version 5.0.2.
I'm using the require function from a C program to load lua functions
and evrything seems to work fine.
As I read,
<<require keeps a table with the names of all loaded files. If a
required file is already in the table, require simply returns. So if I
overwrite a lua file containing a function, to get the new version I
must restart the program.
As I read in the Lua manual, after a successful require"foo",
_LOADED["foo"] will not be nil. If you then assign nil to
_LOADED["foo"], a subsequent require"foo" will run the file again.>>

With this in mind, my aim was to do something like
_LOADED[funcname] = nil everytime I overwrite the file.


My problem is that I'm not able to access this table from my C
program, i.e. I do something like
lua_getglobal(L, "_LOADED");
if (!lua_istable(L, -1))
{printf"_LOADED is not a valid table"); exit(0);}
n = lua_getn(L, -1); n IS ALWAYS ZERO !!!!!!


I try to read my element in the following way:


lua_getglobal(L, "_LOADED");
if (!lua_istable(L, -1))
{printf"_LOADED is not a valid table"); exit(0);}
lua_pushstring(L, funcname);
lua_gettable(L, -2);
if (!lua_isstring(L, -1))
printf("invalid component in _LOADED");
else
myname = lua_tostring(L, -1);
lua_pop(L, 1);


But I always get the message invalid component.


I run the require function before so I expected to find something in
the _LOADED table.
Can anybody please help me to change the _LOADED[] table values from
my C program.


Thank you in advance

But I always get the message invalid component.

On a guess? Does this LUA stuff use any type of OLEServer/ActiveX componentry? If so, judging by the message, it may not be registered...

e.g./i.e.-> regsvr32.exe {componentname}

* What component (DLL/OCX etc.) that is? I have NO idea... just taking a guess here, but, hope it helps YOU 'zero-in' on what the problem MAY be... because it sounds like that to me, like it's trying to make a function call to some library & is unable to marshal it, because it's just not registered via a CLSID.

Lua _LOADED table

Thank you Alec, unfortunately this is not the case, it doesn't use ActveX objects.

No DLL's either? It does sound as if it cannot reference some object/class that would be called from a lib of somekind, but... I don't use that toolset.



* Just guessing, but unfortunately, not right apparently this round... oh well!

P.S.=> Good luck though... apk
