How to do the following SCSS in stylus - css

I have the following SASS function which i am struggling to convert to stylus. The online converters seem to struggle with it also.
#function multiple-box-shadow ($n)
$value: '#{random(2000)}px #{random(2000)}px white'
#for $i from 2 through $n
$value: '#{$value} , #{random(2000)}px #{random(2000)}px white'
#return unquote($value)


The following works.
random(min,max)
return floor(math(0, 'random')*(max - min + 1) + min)px
multiple-box-shadow($n)
$value = random(0, 2000) random(0, 2000) white
for $i in (1...$n)
$value = $value , random(0, 2000) random(0, 2000) white
return $value

<?php
/*

function powerSum($X, $N) {
// Write your code here

$num = 1;
$list = [];
while ( true ) {
$pow = pow($num, $N);
if ($pow > $X) {break;}
$list[] = $pow;
$num ++;
}
$limit = $X;
$array = $list;
// the algorithm is usable if the number of elements is less than 20 (because set_time_limit)
$num = count($array);
//The total number of possible combinations
$total = pow($N, $num);
$out = array();
// loop through each possible combination
for ($i = 0; $i < $total; $i++) {
$comb = array();
// for each combination check if each bit is set
for ($j = 0; $j < $num; $j++) {
// is bit $j set in $i?
if (pow($N, $j) & $i){
$comb[] = $array[$j];
}
}
if (array_sum($comb) == $limit)
{
$out[] = $comb;
}
}
array_multisort(array_map('count', $out), SORT_ASC, $out);
$out = array_unique($out, SORT_REGULAR);
return count($out);
}
}
The above function is working and passing a lot of test cases but fails only due to timeout reasons.
I hope someone will help me fix this problem as soon as possible.
I ran the code on HackerRank, it ran well but failed on test case due to time.

It seems like php malware. You can try wordfence plugin for clean core files etc.

SASS: convert RGBa back to hex?

I am aware SCSS can convert Hex to RGBa, but is there an option for the opposite?
My situation is this: I am given a colour palette that I am not allow to change. This includes a solid accent colour:
$color-accent: #039B15;
I've been asked to use this as a pale background colour, with 80% opacity. That's easy, I can just use rgba():
$color-accent-bg: rgba($color-accent, .2);
However, there is a situation where I need to nest elements with the same opaque background colour - because the colours are opaque they darken when nested.
Is there a way I can convert $color-accent-bg back to hexidecimal with SASS?
Ps: tried using lighten() but that seems to only work up to 66% light.

IMO simple rgba($color-accent-bg, 1) would do the trick - it returns same color as $color-accent.
Otherwise, you can use #ie_hex_str($color). It converts colors to hex string in #AARRGGBB format.
Converts a color into the format understood by IE filters.
Examples: ...
ie-hex-str(rgba(0, 255, 0, 0.5)) => #8000FF00
Since it returns string, you can remove AA part like in last line in following snippet:
$color-accent: #039B15;
$color-accent-bg: rgba($color-accent, .2);
$ie-hex: ie_hex_str($color-accent-bg); //#33039B15
$back-to-color-accent: unquote('#' + str_slice($ie-hex, 4)); //#039B15

Convert RGBa to Hex(transparent. no background, 8-bit color).
Tested solution i have written this code in scss and then converted to sass
In your Scss put:
// convert string to number

You could try #039B1580 but i believe this method doesn't work on all browsers

Variable for adjusting the increase of a numbers value on a curve

I want to increase the value of a number on a curve. I have:
for($i=1; $i<=40; $i++){
$number = cosh($i);
echo $number;
}
This example curves up too fast. How to do I add a variable to this code that will allow me to adjust the rate the number increases? I looking to adjust the slope of the curve. I'm not looking to adjust the value of the beginning number (ie $i = $i*.3).

Countless ways to do this. Here are two:
Change the exponent of $i. Since your starting value is 1, and 1 raised to any power is still 1. Choose a power in the range (0, 1) (non-inclusive), e.g.:
$number = cosh(pow($i, 0.25));
Slightly more general - a power or a multiple of the difference between $i and starting value:
$start = 1;
$end = 40;
$const = 0.01;
for ($i = $start; $i <= $end; $i++) {
$number = cosh($start + ($i - $start) * $const);
// ...
// or...
$power = 0.25;
for ($i = $start; $i <= $end; $i++) {
$number = cosh($start + pow($i - $start, $power));
// ...
// or a combination of both.

if you don't want to change $i in the for definition, change it within the function call:
for($i=1; $i<=40; $i++){
$number = cosh($i*.3);
echo $number;
}

How to create multiple box-shadows in a Stylus function

I found a SASS function for "starry sci" creating:
// n is number of stars required
#function multiple-box-shadow ($n)
$value: '#{random(2000)}px #{random(2000)}px #FFF'
#for $i from 2 through $n
$value: '#{$value} , #{random(2000)}px #{random(2000)}px #FFF'
#return unquote($value)
#stars{
box-shadow: multiple-box-shadow(700)
}
I want to translate it to Stylus, but something doesn't work. I try:
random(min, max)
return floor( math(0, "random") * max + min )
$coordinates = random(1, 2000)px
$distortion = random(1, 20)px
// n is number of stars required
multiple-box-shadow($n)
for $i in (1..$n)
$value = $coordinates $coordinates $distortion $distortion #FFFFFF,
return $value
#stars
box-shadow multiple-box-shadow(700)
random function run only ones and the box-shadow value add only once...
Can anybody help?
Here's a CodePen snippet to view compiled CSS

Something like:
random(min, max)
return floor(math(0, 'random') * max + min)
multiple-box-shadow($n)
$value = '%spx %spx #FFF' % (random(1, 2000) random(1, 2000))
for $i in 2..$n
$value += ', %spx %spx #FFF' % (random(1, 2000) random(1, 2000))
return unquote($value)
#stars
box-shadow: multiple-box-shadow(700)

My colleague suggested this solution to me:
random(min, max)
return floor( math(0, "random") * max + min )
// n is number of stars required
multiple-box-shadow($n)
$coordinates = random(1, 2000)px
$distortion = random(1, 20)px
$value = $coordinates $coordinates $distortion $distortion #FFFFFF
for $i in (2..$n)
$coordinates = random(1, 2000)px
