Feel free to delete this post if you don’t feel that this fits though I think the language I use is very similar to bash in some ways (G’MIC). Here’s a real-world example of my own code in G’MIC that’s pretty much painful to parse:

command "out2display : skip ${""1=},${""2=},${""3=},${""4=1},${""5=1},${""6=},${""7=},${""8=},${""9=},${""10=} if narg($""1) if $""1 $__bg rv blend alpha fi fi xalp if narg($""6) if narg($""2)&&narg($""3)&&narg($""4)&&narg($""5) {$""4},{$""5},1,{s#0},i(#-1,$""2+x,$""3+y) f. begin(ww=w-1;hh=h-1;);(x<(2+narg($""7))||x>ww-2)||(y<(2+narg($""7))||y>hh-2)?(xor($""6,i)>128?0:255):i j[0] [-1],$""2,$""3 rm. if narg($""8)&&narg($""9)&&narg($""10) if $""8==0||$""8>2 {$""4},{$""5},1,{s#0},i(#0,$__nw+($__min_tile*$""9)-$""2+x-$""4,$""3+y) f. begin(ww=w-1;hh=h-1;);(x<(2+narg($""7))||x>ww-2)||(y<(2+narg($""7))||y>hh-2)?(xor($""6,i)>128?0:255):i j[0] [-1],{$__nw+($__min_tile*$""9)-$""2-$""4},$""3 rm. fi if $""8==1||$""8>2 {$""4},{$""5},1,{s#0},i(#0,$""2+x,$__nh+($__min_tile*$""10)-$""3+y-$""5) f. begin(ww=w-1;hh=h-1;);(x<(2+narg($""7))||x>ww-2)||(y<(2+narg($""7))||y>hh-2)?(xor($""6,i)>128?0:255):i j[0] [-1],$""2,{$__nh+($__min_tile*$""10)-$""3-$""5} rm. fi if $""8==2||$""8>2 {$""4},{$""5},1,{s#0},i(#0,$__nw+($__min_tile*$""9)-$""2+x-$""4,$__nh+($__min_tile*$""10)-$""3+y-$""5) f. begin(ww=w-1;hh=h-1;);(x<(2+narg($""7))||x>ww-2)||(y<(2+narg($""7))||y>hh-2)?(xor($""6,i)>128?0:255):i j[0] [-1],{$__nw+($__min_tile*$""9)-$""2-$""4},{$__nh+($__min_tile*$""10)-$""3-$""5} rm. fi fi fi fi if narg($""7) f[0] begin(ww=w-1;hh=h-1;);(x%$__min_tile==0||y%$__min_tile==0)||(x==ww||y==hh)?$""7:i fi"

That was before I figured out how to properly code in local commands.
