For those who are accessing Lua from C++ code,
this may be of interest.
I have implemented a C++ API to access and manipulate Lua values.
It consists of a header file (lua++.h) that defines a few classes
that naturally bind Lua objects to C++ type and vice-versa.
For instance, if we have the following Lua code:
myTable = {name = "lua++"}
It is valid to write a C++ code like this one:
...
LuaObject t = Lua:getglobal("myTable"); // access the table object
LuaObject f = Lua:getglobal("print"); // access the pre-defined function
f(t["name"]); // call Lua function
...
which will output the string "lua++".
Also, if we have a Lua function:
function myFunc (a,b)
print(a+b)
end
We can call it from C++ code doing:
...
LuaObject f = Lua:getglobal("myFunc");
f(5,7);
...
It is still a beta version, but if you want to try it
and help me to improve it, the code and a naive documentation
can be reached at:
