function list not working for lua script

[Kesler Sullyvan]

I’ve already tried adding new code into the function .xml file, but it doesn’t seem to be working, this code btw. Even basic functions don’t show up on the list:

function max(num1, num2)

   if (num1 > num2) then
      result = num1;
   else
      result = num2;
   end

   return result; 
end

-- calling a function
print("The maximum of the two numbers is ",max(10,4))
print("The maximum of the two numbers is ",max(5,6))

I also already tried updating, and using portable versions, but nothing. Am I doing something wrong here?

That’s because the instructions at that site were written for v7.9.0 and earlier; v7.9.1 and newer separate out each functionList configuration into a separate file.

In your installed Notepad++, go to %AppData%\Notepad++\functionList\ folder 🛈, and copy one of the other language XML files to lua.xml. Replace the <parser ...> section with the <parser ...> from that other site: it will look like:

<?xml version="1.0" encoding="UTF-8" ?>

Unlike the site says, you don’t need to check or change an <association> tag or edit the new overrideMap.xml, because Lua defaults to lua.xml.
Exit Notepad++ and restart. The source code you showed will then show functions

Oh wow! Thanks so much! I still don’t know what worked, but as soon as I dropped your code into the functionlist folder, it clicked. Honestly, I don’t really code at all. I messed around with bots a while ago, but nowadays I just really enjoying organizing my texts using Lua on N++. I’m glad I posted, you made my day :)

@PeterJones Your code helped me too.
