It's about my suffix type question: I just found out that the top voted haskel answer returns a list instead of a string like I assumed. I stated in a comment to "please output only a single char for each input char. ". Should I simply allow lists for all or should I make it more clear that I want a string and notify the author?

How do you make a code block in the chat?
Alright, found it
@Adám I don't know Charcoal, maybe. The idea here is to have functions for printing not only line by line, but directly like on a real board
@LuisMendo Thanks Luis! To be honest, the lack attention (and votes) took me by surprise too. I changed it to Game of Life and Fatigue per your suggestion... It's a much better title :)
hmm, how would I grep to find files that include 2 lines, regardless of their position relative to eachother? I could do grep -P /line1.*line2/s but that would only show if line2 is after line1
or better yet how would I write a sed to remove line2 in those files?
Implement the very first sed command in history
So, suppose we are just beginning to program and we do not have any sed-like command yet. How would you implement it?

Uses unicode arrows like ↓ to draw lines, and shapes like ■ to draw shapes. Not documented at all, but if you want to see how it works the code is on github.
Charcoal is definitely the best one that's actually usable
@DestructibleLemon The drawing thing would be for ascii art, but wouldn't be the main purpose of the language. What I wanted was a golfing lang, like Japt, but with functions to do ascii art if needed
I couldn't find any language that combined both being a really short golfing language and being good at ascii art; and I don't have the time to make one myself :'(

Given an array of positive integers and two distinct valid indices, return the array with the two elements corresponding to the two indices swapped.
You may choose to use 0-indexing or 1-indexing, but the testcases below will be 0-indexed.

@Dennis what are different lock reasons? I don't seem to be able to find a meta post...(that is, let's rather not make a looooong comment discussion :P)
and I think that all of them at least lock the question, so it still can't be undeleted...unless some are half locks
I know some of them like dispute-locks don't lock the answers...
@EriktheOutgolfer Of course they all "lock" the question. That just means different things for different lock reasons. If I lock it for Offtopic comments, I suspect it could be undeleted.
The others are Content dispute and Wiki answer. The first would fit marginally better, but I know for a fact that it's weaker than HS.
I've read somewhere that they do...anyways, if not so, then the answers could stay unlocked and I don't think that content dispute will let you undelete the question...of course you can't test that in practice
oh wait, editing deleted answers bumps the question though
M <any> def g(G,H): return A. g -> n ->
M <pf1> <col> Map. Map A(_) over B, where _ is the lambda variable. Map uses m underneath.
M <pfn> <col(seq)> Map. Map A(*_) over B, where _ is the lambda variable. Map uses m underneath. Each element of B is splatted as the arguments to A.
@KritixiLithos I think the mass downvoter was juniorRubyist, they downvoted because they thought only functions were allowed by the meta consensus. You know, that user that told me: "Thank you for grief". Or was it another wave of downvotes (after that one)?
@LeakyNun No I'm good, I finally noticed the word "preceding" in the description of <pfn>. It makes sense now: pfn = Preceding function of arity n. *F, for instance.

Not yet; they want me to create new profiles in all of the accounts that I want to keep, and they can remap all of the content back into my profile (which from my understanding should merge the two and add my past rep into my current rep hopefully)
@KritixiLithos lol I want the votes remapped too because pretty much every single active PPCG user lost rep; e.g. Dennis lost 148 rep rip
Also apparently I was reported, and they did read chat, and they thought I was trying to avoid deletion because immediately after realizing the restriction I cleared every single PII on my profile lol
@flawr 3 reasons. 1: I said something about it in chta that made it seem like I was <13. 2: I cleared all of my PII very rapidly after that which made it suspicious. 3: Someone reported me.
@LeakyNun Typo. Thanks! I've never used J so I didn't realize there would be a builtin for it /: maybe I could convert this into a "best-algorithm" question? — musicman5232 mins ago
