My attempt at a cli dnd dice roller. I'm going to over-engineer the crap out of this...

go get github.com/3xcellent/go-roll

go-roll d20 - roll a 20-sided die

go-roll d20h - roll twice and keep the highest (i.e. w/ advantage)

go-roll d20l - roll twice and keep the lowest (i.e. w/ disadvantage)

go-roll d20+2 - add modifier to roll

go-roll 4d8 - roll 4 8-sided die

syntax can be combined, but doesn't always make sense go-roll 100d100h+99

Sometimes you like to see what the system rolled for you:

go-roll -v 2d20+9

will output something similar to:

Rolls: 18, 19
Modifier: +9
Total: 46 (min/max 11/49)

• go-roll is only parsing modifiers up to two characters currently. If there's a good reason to add modifiers for numbers higher than 99, please create an issue.
