Hello All,
I found interesting problem while I try Lua 5.0.2 (Actualy I didn't know where is problem in my C code for working with XML files or in Lua) I got error message: test.lua:35: attempt to perform arithmetic on a string value
This line looks: printf("Test %d\n",1+1);
Also if I try make instand of callig printf
a=0
a=a+1
printf("And value is %d\n",a)
Result:
And value is 0
Anybody known where may be problem?
This is part of code:
...
function printf(...)
 io.write(string.format(unpack(arg)))
end
function space(ix)
 while ix > 0 do
 ix=ix-1
 printf(" ")
 end
end
function enumerateBxmlTree(bxml,id,level)
 local idInfo,bxmlName,bxmlValue,ids
 ids = id;
 if ids == nil then ids=0 end
 idInfo=Bxml.enum(bxml,id)
 while idInfo ~= nil do
 bxmlName=Bxml.name(bxml,idInfo)
 bxmlValue=Bxml.value(bxml,idInfo)
 if bxmlName == nil then bxmlName="" end
 if bxmlValue == nil then bxmlValue="" end
 if Bxml.links(bxml,idInfo) > 0 then
 space(level)
printf("<section name=\"%s\" value=\"%s\">\n",bxmlName,bxmlValue)
 enumerateBxmlTree(bxml,idInfo,level+1)
 space(level)
 printf("</section>\n")
 else
 space(level)
 printf("<entry name=\"%s\" value=\"%s\"/>\n",bxmlName,bxmlValue)
 end
 idInfo=Bxml.enum(bxml,id,idInfo)
 end
end
-- anything here is non numerical???
printf("Test %d\n",1+1);
I tried the code above (with Lua 5.0) and I got:
Test 2
And value is 1
to:
printf("Test %d\n",1+1);
a=0
a=a+1
printf("And value is %d\n",a)
So it seems normal to me...
OK, I compiled Lua 5.0.2, same result. I guess the problem is within your code...
