SUPERAPIHOOK_SetItemButtonCount Fixes/Updates

[veechs]

Updates to SUPERAPIHOOK_SetItemButtonCount:

• Prevent error Interface\AddOns\SuperAPI\SuperAPI.lua:123: attempt to perform arithmetic on localcount' (a string value) when count < -999.
• Allow Blizzard code to handle the basics and just worry about font color. (This also requires resetting button.count to 0 so the split stack code doesn't get confused.)

I just realized that always relying on Blizzard code means that when charges is at 1, they’ll be hidden just like count, which is probably why you didn’t write it that way. So if that’s your goal, feel free to ignore this (you’ll probably still want to fix the string concatenation bug though).

A simple fix for only the concatination issue would be:

function SUPERAPIHOOK_SetItemButtonCount(button, count)
    if not button or not count then
        return SUPERAPIHOOK_SetItemButtonCountOriginal(button, count)
    end
    if (count < 0) then
        getglobal(button:GetName().."Count"):SetText((count < -999) and "*" or math.abs(count));
        getglobal(button:GetName().."Count"):Show();
        getglobal(button:GetName().."Count"):SetFontObject(NumberFontNormalYellow);
    else
        getglobal(button:GetName().."Count"):SetFontObject(NumberFontNormal);
        SUPERAPIHOOK_SetItemButtonCountOriginal(button, count)
    end
end
