Long prime list - filter version - 19 entries

I've used the maximum input/diff/output size allowed by vimgolf to get a list of integers up to 1460 separated by newlines, and your goal is to only keep the lines containing primes. There are 232 of them I hope some of you will golf vimscript itself to create some function to run as a primality check for each line, which is a good exercise if you haven't done much vimscript yet! You're invited to also try copy-pasting and doing other non-smart text manipulation. Even more interesting would be to see a solution that uses text manipulation to do the filtering! Whether you use vimscript, normal-mode primality checks, or text manipulation, as long as the end result is valid, your answer will be valid! Let's see which method does better here. Best of luck!

Change The Perspective - 31 entries

This is a go game recodes file(.sgf file, refer to http://www.red-bean.com/sgf/). It base on such a coordinate system: in vertical direction, is from top(farthest end) to bottom, mark as a,b,c,...,s(19*19 board); in horizontal direction, is from left to right, uses the same notations. For Example, the coordinate notation 'cq', is the position at the bottom-left corner(vertical coordinate first). The record is from one player's perspective. We need to change to another's, but we don't want to change coordinate system, let it keep top to bottom and left to right. so we have to change the coordinates, a <-> s, b <-> r,c <-> q, etc. the Position 'cq', as transformation, it will be 'qd'.
