Parentheses to left of colon operator optimised away

[going-digital]

Pakettic fails on this example:

function TIC()
    cls()
    print(("abc"):sub(1, f//10 % 4 + 1),0,0,12, false, 1)
    f = f + 1
end
f=0

Pakettic optimises ("abc"):sub() to "abc":sub(). This breaks the code. In Lua, ("abc") is a string object, but "abc" is a literal which doesn't have string methods.

Workaround: Use an intermediate variable.

function TIC()
    cls()
    x="abc"
    print(x:sub(1, f//10 % 4 + 1),0,0,12, false, 1)
    f = f + 1
end
f=0

Should be fixed, can you try: pip install git+https://github.com/vsariola/pakettic.git@main to check if it resolves your issue.

If it's ok, I probably should release a minor release before lovebyte, as there's now two bug fixes already there. This one of yours was actually possible to encounter in sizecoding, the other one is more rare.

Working well - thanks for the fix!
