@Leo answer with explanation. hope that helps

@MartinEnder it did, thank you :)

And I found a way to save bytes on the first jump tio.run/nexus/…

oh that's really neat, I'll edit that later

I tried a different approach for the Ordinal formatter, but currently it's 4 bytes longer (probably because it needs 4 bytes to pad the input to even length, because the general approach doesn't work for odd length) tio.run/nexus/alice#@x/…

it's also one of those times where I wish the return address stack did store the direction...

managed to tie yours: tio.run/nexus/alice#@6@fq66nVZVbVx6ll23NFeNpraAYaR8UpOcf6aD//…

I also wonder why we don't always use this layout, it seems to save a byte

(so the original 28-byte solution might be 27 using this)

I guess it only works code sizes which are 0 or 1 (mod 4)

oh nevermind, it's also the same byte count in general because we still have 3 mirrors. it just saved something here because my original had 4 mirrors and I needed to waste some bytes because w and k weren't moving in the same direction otherwise

For future reference: ordinal mode formatter, left to right mode

(same as the old one, just doesn't reverse the second half)

nice :)

I think it needs some rearranging for code length 1 and 2 (mod 4) though

(because the way it's output now, the code doesn't end in the bottom right corner then)

@MartinEnder I think it's enough to place mirrors and @ accordingly

oh you're right, that still works

Bug report: , in cardinal mode with negative argument seems to perform conversion to get the top stack element tio.run/##S8zJTE79/1/fX11BlSvG00FBQd8oSCchRe3//…

(could be a feature and not a bug, but the documentation says otherwise)

definitely a bug, thanks

should be fixed on GitHub, but I'll wait with requesting a TIO update until I have time to test the fix properly

@Leo fixed

kudos if you can find a way to get rid of the @ or the ;

@MartinEnder you almost had it :) tio.run/nexus/alice#@x@jEsIVo5qv/v8/AA
