This project has a GUI where you set a list of n dice each with x sides then use mouse activity to generate randomness which is used to determine the rolls.

This is a command line program for rolling dice.
The dice rolls are generated, in part, using your mouse movments to make it feel more like actually rolling dice.

The program takes in args in the following format <number>d<sides>[,<keep>][,<group_copies>]
<number> is the number of dice to roll
<sides> is the number of sides on the dice
<keep> is the number of dice to keep
<group_copies> is the number of times to roll the group of dice
You can pass in multiple dice groups at a time sperated by a space. ./cli_dice.exe 4d6 1d20

You can also use the -i flag to read in a yaml file to reroll the same dice from your previous roll.
Optionally you can lock in the values of some of the rolls.

./cli_dice.exe 4d6,3,6
4d6 You want 4 six sided dice (This will be enough to calculate one ability score).
3 you only want to keep the values of the top 3 roles
6 you want 4d6,3 6 times for each ability score.
Your output would look like this:

Netting you the following roll values:
13,12,9,14,8,14

./cli_dice.exe 1d20
1d20 You want 1 twenty sided dice
Your output would look like this:

┏━━━━━━━┳━━━━━━┳━━━━┳━━━━━━━┳━━━━━━━━━━━━┓
┃ d20   ┃ roll ┃ k1 ┃ Total ┃ Keep Total ┃

└───────┴──────┴────┴───────┴────────────┘

./cli_dice.exe 5d6
5d6 You want 5 six sided dice
Now lets say you want to keep the 3 highest rolls rerolling the other 2
Your first command generates a dice.yaml file that can be modified to lock in the dice you want to keep.
./cli_dice.exe -i dice.yaml will read in your previous rolls and only reroll the dice you didn't lock in.

Lets keep the 3 highest rolls by setting locked to true and reroll the other 2 dice
Update dice.yaml:

- dice:
  - 1_value: 1
    2_locked: false
  - 1_value: 3
    2_locked: false # Change me from false to true
  - 1_value: 4
    2_locked: false # Change me too
  - 1_value: 1
    2_locked: false
  - 1_value: 3
    2_locked: false # Change me too
  keep: 5
  sides: 6

After updating the dice you want to lock in to true reroll
./cli_dice.exe -i dice.yaml
After

- dice:
  - 1_value: 4
    2_locked: false
  - 1_value: 3
    2_locked: true
  - 1_value: 4
    2_locked: true
  - 1_value: 3
    2_locked: false
  - 1_value: 3
    2_locked: true
  keep: 5
  sides: 6

We went from: 1,3,4,1,3 to 4,3,4,3,3
You'll notice we retained the two 3s and one 4 from the previous roll and our two 1s rerolled into 3s.
