Thanks! I still have a question, anyone ping me if I can ask them live?

@DuctrTape you can try :)

So I'm trying to solve the clock challenge. Using ØHḟp” (trailing space) I can create what I think is the map to replace everything but the input into a space (input in hex for now).

But I can't get it to act as a map, see here (as a nilad for first experiments).

If If just take the output from ØHḟp” as a string literal it does work, but not if I use it as a niladic chain.

You need a single list: TIO

also, not sure if the compression will be of use here

Wasn't it a list? And it should save 2 bytes.

It was a list of lists

I can do 29 with both a string and a compressed string, although the former can go in one link.

... in fact 28

Neat! what does µ do there?

it's monadic chain separation

basically saying everything to the left should be parsed as a one-input function (the implicit input is 0)

Yeah, I've read that a few times.

Anyway, thanks!

@DuctrTape might be better to use a base250 compressed number to store indexes into a string that is mostly spaces. I'll give it a go.

How do you mean?

make a string just with the * and O and the rest spaces, then place the other * in at a location by looking it's index up in a list formed from a base conversion of a number using the base-250 compression form.

So for each time you look up where it should be inserted? Looking forward to see that!

@DuctrTape posted a preliminary version, it may well be golfable.

That's already a lot better than what I've been trying so far.

Looking forward to an explanation because don't understand everything yet.

yeah I will post one, I always do :)

What exactly does the ¤ do? I figured it takes the left side as a nilad (a constant) - but what about the right side (the followed by a nilad part)?

It tells the parser that stuff to the left is of the form nilad + some link(s) (+possible last nilad). It does not do anything specific to the right hand side, other than that direct effect.

found a two byte save using some of my own contributions...

oh 1 byte :(

the "+ some links" are also in the left side?

yeah, so the code could end with a nilad too (since you dont need it for a single nilad on it's own and it's useful to be able to end with one, a simple example might be that you want the string "123456 " within your chain, and you know you can join a space onto the end of the list [1,2,3,4,5,6] to do so, so you want to do 6R;⁶ but you want that all as one nilad...

so you add the ¤ to instruct the parser that's what you want - it goes left to the next nilad, but ignores the ⁶, since if you just want a space you dont need the ¤.

if you have two nilads in the piece of code you may need to use two ¤, but then it might be cheaper (or the same and more readable) to use ¢.

@Dennis - we had ṖṖCG, now we have tI©! ...ị“ tI©’Œ?Ḋ¤µ⁶ẋ13”*⁸¦Ṗ;“**o”ṙ7s5ZY

Alright, that's a good explanation, I think I get it now.

I just used Æ¡ in an answer; now I'm curious as to how often it's useful

it seems fairly specific

@JonathanAllan The separators apply to the chain to the right, not the left.

oops yes "everything to the left is the input into" was what I had meant

@JonathanAllan That's probably at least as useful as the list.

cool beans :)

Oh yey ,v.cool...
