Lua - Iterate Through Table With nil Values
- by Tony Trozzo
My lua function receives a table that is of the array form:
{
field1,
field2,
nil,
field3,
}
No keys, only values. I'm trying to convert this to a pseudo CSV form by grabbing all the fields and concatenating them into a string.
Here is my function:
function ArenaRewind:ConvertToCSV(tableName)
csvRecord = "\n"
for i,v in pairs(tableName) do
if v == nil then v = "nil" end
csvRecord = csvRecord .. "\"" .. v .. "\""
if i ~= #tableName then
csvRecord = csvRecord .. ","
end
end
return csvRecord
end
Not the prettiest code by any means, but it seems to iterate through them and grab all the non-nil values. The other table iteration function is ipairs() which stops as soon as it hits a nil value.
Is there any easy way to grab all of these fields including the nil values? The tables are various sizes, so I hope to refrain from accessing each part like an array [i.e., tableName[1] through tableName[4]) and just grabbing the nil values that way.
Thanks in advance.
