Hi Hans,
i'll bypass that warnign when the mode is zero
I saw that you made that change in the latest upload, thanks. Unfortunately, I'm still getting the same output: luatex warning > linebreak: list seems already prepared luatex warning > linebreak: [ leftinit | rightinit | leftfill | rigthfill ] expected nil Also, what's causing me issues isn't the warning but rather that tex.linebreak is returning nil instead of an info table as the second return value.
btw, you need to work with a copy of the list
Now that you point that out, I'm actually surprised that that example worked at all. The real code does use a copy of the list though (and also uses the proper callback interfaces instead of "system.callbacks. permitoverloads") Thanks, -- Max
