Hi there, thanks a lot for this neat utility, I use it every day on my work computer.
In certain scripts I make use of negative numbers to indicate a further decrease in the output value. Wob indicates them in red which fits this use case nicely.
Nevertheless, it seems that negative numbers are somehow offset?
-1 displays a nearly empty bar and decreasing the input decreases the bar until -17 suddenly wraps around and displays a nearly full red bar (with -16 being an empty bar).
Decreasing the numbers further reduces the red bar intuitively but with and offset of 16.
I therefore wanted to ask, are negative numbers officially supported by wob? And if so, is this behavior known or might there be a bug hiding?
Thanks for the help.
EDIT:
I have just seen that input is assigned to an unsigned long:
(https://github.com/francma/wob/blob/729e5c68215547eb8939c4c1778f58cca36b2bc0/src/wob.c#L367)
So -1 just overflows and wraps around, wob handling it as (2^64 - 1) % 100 = 15
hence the offset I've observed.
For now I've just offset my script output as a workaround but I think it would be nice to have official negative numbers support, would you be open to it @francma ?
