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.
