Add support for negative values

[Bernardo-MG]

Currently only positive integers are supported, not counting the subtraction operation.

dyce will do this. It's pretty flexible on what it accommodates as outcome (face) types:

>>> from dyce import H
>>> H(-6)   # d6, but with negative faces
H(-6)
>>> 2@H(-6) - 20  # 2d(-6) - 20
H({-32: 1, -31: 2, -30: 3, -29: 4, -28: 5, -27: 6, -26: 5, -25: 4, -24: 3, -23: 2, -22: 1})
>>> _.roll()
-22

>>> from dyce import P
>>> 3@P(-20)
P(-20, -20, -20)
>>> _.roll()
(-20, -16, -14)

You'd have to settle on a grammar, but you might be able to lean on it under the covers if you can identify something you like.

I'm happy to consult on this, if there's interest.

Thanks. I haven't touched this project in a long time, but if I recall correctly the current version is generated from an ANTLR grammar. This grammar: https://github.com/antlr/grammars-v4/tree/master/dice

I created it for another project (https://github.com/Bernardo-MG/dice-notation-java/), and adapted it for usage on Python.

At this moment I'm not planning on moving on with this project, as I don't have time for it. But thanks for the offer.

Thanks for the attention and the response! Good luck on whatever's keeping you busy these days! 😁
