Simple Nightbot command to roll any number of any kind of dice

$(eval var i=parseInt,d=[],e='$(provider)'=='twitch'?'melziiD20':'🎲20',j=0,l,m='$(query)'.match(/^(([0-9]+)\s+)?(([0-9]+)?d([0-9]+)|([0-9]+))$/)??{},c=i(m[2]??1),n=i(m[4]??1),s=i(m[5]??m[6]??20);c=c>20?20:(c<1||!c?1:c);n=(n<1?1:n);s=(s<1?1:s);for(;j<c;j+=1){d.push(Math.round(n*(s-1)*Math.random())+n)}r=`$(user) rolled ${d.join(', ')} with ${n<2?'a ':n+'×'}🎲`+s;l=r.lastIndexOf(',');(l<0?r:r.substr(0,l)+' and'+r.substr(l+1)).replace(/( |🎲)20(,| |$)/g,` ${ e } $2`))

Examples:
!roll - PakL rolled a 2 with a 🎲6
!roll 20 - PakL rolled a 14 with a 🎲20
!roll 2d6 - PakL rolled a 11 with 2×:game_die:6

Or something absurd like:
!roll 15d19 - PakL rolled a 118 with 15×:game_die:19
!roll 5d1 - PakL rolled a 5 with 5×:game_die:1

Any 20 will be replaced by the emote. d20 is now the default instead d6 and I also added the capability to make up to 20 throws at once:
!roll 20 d20 - PakL rolled 13, 6, 4, , 8, 19, 19, 2, 13, 15, 6, 3, 5, 7, 12, 14, 10, 1, 11 and 5 with a

• Fixed a bug that prevented users to use other dice than d20 when outputting multiple throws and prefexing dice with a "d". (Thanks @MontageTM)
• Removed Discord emote as bot cannot use them across servers anymore.

source.js

var i = parseInt,
	d = [],
	e = '$(provider)'=='twitch'?'melziiD20':'🎲20',
	j = 0,
	l,
	m = '$(query)'.match(/^(([0-9]+)\s+)?(([0-9]+)?d([0-9]+)|([0-9]+))$/) ?? {},
	c = i(m[2] ?? 1),
	n = i(m[4] ?? 1),
	s = i(m[5] ?? m[6] ?? 20);

c = c > 20 ? 20 : (c < 1 || !c ? 1 : c);
n = (n < 1 ? 1 : n);
s = (s < 1 ? 1 : s);
for(;j<c;j++) d.push(Math.round(n*(s-1)*Math.random())+n);

r = `$(user) rolled ${d.join(', ')} with ${n < 2 ? 'a ' : n + '×'}🎲` + s;
l = r.lastIndexOf(',');
(l < 0 ? r : r.substr(0, l) + ' and' + r.substr(l+1)).replace(/( |🎲)20(,| |$)/g,` ${e} $2`);

If this is still active... Is there a way to remove so this doesn't show up?

I'm guessing you mean the D20 emote? Sure, you can easily remove that by setting the e variable to 🎲20:

$(eval var i=parseInt,d=[],e='🎲20',j=0,l,m='$(query)'.match(/^(([0-9]+)\s+)?(([0-9]+)?d([0-9]+)|([0-9]+))$/)??{},c=i(m[2]??1),n=i(m[4]??1),s=i(m[5]??m[6]??20);c=c>20?20:(c<1||!c?1:c);n=(n<1?1:n);s=(s<1?1:s);for(;j<c;j+=1){d.push(Math.round(n*(s-1)*Math.random())+n)}r=`$(user) rolled ${d.join(', ')} with ${n<2?'a ':n+'×'}🎲`+s;l=r.lastIndexOf(',');(l<0?r:r.substr(0,l)+' and'+r.substr(l+1)).replace(/( |🎲)20(,| |$)/g,` ${ e } $2`))

Or even better, edit the command so when someone does !roll it shows them rolling 3 dice on a 6 sided dice like this instead of me having to do !roll 3 6?

You can change the default roll by changing the defaults in the c (number of throws, max. 20), n (number of dice per throw), and s (number of sides on dice) variables. Your example would be:

$(eval var i=parseInt,d=[],e='🎲20',j=0,l,m='$(query)'.match(/^(([0-9]+)\s+)?(([0-9]+)?d([0-9]+)|([0-9]+))$/)??{},c=i(m[2]??3),n=i(m[4]??1),s=i(m[5]??m[6]??6);c=c>20?20:(c<1||!c?1:c);n=(n<1?1:n);s=(s<1?1:s);for(;j<c;j+=1){d.push(Math.round(n*(s-1)*Math.random())+n)}r=`$(user) rolled ${d.join(', ')} with ${n<2?'a ':n+'×'}🎲`+s;l=r.lastIndexOf(',');(l<0?r:r.substr(0,l)+' and'+r.substr(l+1)).replace(/( |🎲)20(,| |$)/g,` ${ e } $2`))
