redefined-local for loop variables

[rolandlo]

When using something like

for i = 1, 10 do
  -- whatever
end

-- more code

for i = 1, 20 do
 -- whatever
end

I get a Redefined local i warning. Is it really bad style to reuse the same name (i) for a loop variable? Or can I disable warnings like that?

Do you have i defined somewhere else in the same code block? Example:

local i = 1

for i = 1, 10 do
  -- whatever
end

-- more code

for i = 1, 20 do
 -- whatever
end

When I copy/paste the example code you provided, I do not get any warnings. But if I define i, like in the example above, I get the warning you are seeing.

You're right, I had i defined as part of an outer loop, which is kind of shocking. Clearly I shouldn't give the loop variables in an outer and inner loop in the same way. Thanks for the help!
