<oerjan> addquote <kspalaiologos> I have made a chess engine in Malbolge <kspalaiologos> in theory it\'s decent <kspalaiologos> but it has two drawbacks <kspalaiologos> a) It requires 31 and a half gigabytes of memory <kspalaiologos> b) it\'s quicker to count atoms in universe than to run it

#!/bin/sh
count () {
    hg log --template '{desc}\n' |
    egrep '<[^]]*> karma\'$1 |
    fgrep -vix "<$2> karma$1 $2" |
    cut -d' ' -f3 |
    fgrep -cix "$2"
}
plus=$(count + "$1")
minus=$(count - "$1")
echo $(($plus-$minus))
