Simple dice engine written in C#.

Embed into your project or use the CLI to play around.

Arithmetic (+, -, *, /, %)

Rolling dice (<num>d<faces>)

Dice modifiers (<num>d<faces>[<modifier><operator><argument>])

> 6d6cs>4
2

Valid modifiers are cs (count successes), x (explode), cx (compound explode), ms (margin of success), r (reroll), kh (keep higehst), kl (keep lowest), dh (drop highest), dl (drop lowest).

Dice pools ({<expr>[, <expr>[, ...]]}<modifier><operator><argument>)

> {1, 2, 3}kh=1
3

> {}

Valid modifiers are cs (count successes), kh (keep higehst), kl (keep lowest), dh (drop highest), dl (drop lowest).

Comparison (==, !=, <, <=, >=, >, <condition> ? <true-branch> : <false-branch>)

> 2 > 1
True

> 6 < 1d8
False

> 6 < 1d8
True

> 1d8 > 4 ? 20 : 1
1

> 1d8 > 4 ? 20 : 1
20

Functions (floor, ceil, round, min, max)

> 1.5
1.5

> floor(1.5)
1

> ceil(1.5)
2

> min(5, 2, 4)
2

> max(5, 2, 4)
5

This code is heavily based on the Java code for Lox, the language from http://www.craftinginterpreters.com, mainly chapter two. Check it out if you want to lern how to build interpreters!
