# dicebox
A simple dsl for dice.
```python
>>> import pandas as pd
>>> from dicebox import d
```
```
>>> d(100) + 5
<DiceExpr(1d100 + 5)>
```
```python
>>> str(d(6) + d(6)) == str(d({6: 2})) == str(d(6, 6)) == "(2d6)"
True
```
```
>>> d(8, 6, 6, 6) // 2
<DiceExpr((1d8 + 3d6) // 2)>
```
```
>>> d({8: 1, 6: 3})
<Dice(1d8 + 3d6)>
```
```
>>> d(10) + 5 + (d(20) + d(8))
<DiceExpr(1d10 + 5 + 1d8 + 1d20)>
```
```python
>>> d(20).adv.roll(2)
array([17, 17])
```
```python
>>> n = 100000
>>> adv = (pd.Series(d(20).adv.roll(n)).value_counts().sort_index() / n)
>>> disadv = (pd.Series(d(20).disadv.roll(n)).value_counts().sort_index() / n)
>>> norm = (pd.Series(d(20).roll(n)).value_counts().sort_index() / n)
```
```
>>> (d(20).adv - d(20).disadv) * 2
<DiceExpr((adv(1d20) - disadv(1d20)) * 2)>
```
**todo:**
- [ ] pdist (incl composability)
- [ ] roll logging
- [ ] better expr collapse (sympy?)
- [ ] better DiceExpr str rendering
- [ ] DiceExpr.parse
- [ ] visual output (w/ scavegr)
