@Pavel That by itself is useful information. How are errors handled? TIO has a separate box for those, not sure if I have to do anything special (just let the console program crash?).

@Draco18s The error box on TIO is just the output from STDERR
Is it possible to recover an account that was explicitly deleted by a Stack Exchange team member (as opposed to an elected diamond moderator)? That is, the kind of account where the user requested the deletion, or committed atrocities against the community?
I made the decision to tightly integrate this into SE. Literally the only way to login is to use SE Oauth
This has several benefits: I don't have to handle authentication, the instant you log in, all of the submissions you've ever made are already there, and I can automatically use the challenge creator's account to update posts
I do think in the future it'll be possible to make a non-SE challenge, but I would prefer to get it up and running first
sorry, definitely not at the start. Nothing in the DB is intrinsically tied to SE (I simply have refIDs), but making things more generic also increases the cost
@Neil Thanks for the reply. My main question is actually how to do "then for each character in the input, perform any appropriate rotation". I only know the basics of regex, but not really the special commands of Retina, so I'm a bit embarrassed to admit I don't know how to for-each over each character to perform some replacements inside the loop.
@KevinCruijssen My approach would be to have an input line and an output line and transfer characters one at a time from one to the other, then wrap the whole lot in a looped group
@Neil Do you perhaps have some existing Retina answers where you did something similar? Usually having an example helps me better understand how it is done in general.

This challenge involves a simplified version of the card game ...
@Neil Thanks, that looks like a promossing example. Will see if I can make something later today (or tomorrow if my current work priorities take too much time). Will let you know if/when I posted an answer or if I have more questions. :)
Challenge: write a function that produces a string or a list containing all possible lambda functions (if it were allowed to run forever). Start with then simplest lambda expression.
If you produce a string be sure to separate each lambda function with a given character, say a pipe | or a semi-c...
@Neil Ah ok, then mine is 1 byte longer. Will see where I can golf mine. Since a trailing newline is acceptable in other languages I figured it's also allowed for Retina, hence why it's in the footer
@ThomasWard Yeah, and my fingers have a habit of typing whatever they want to, I use my backspace key.....4.2% of the time (a little more than the letter N and about as often as Shift). "<./div<, no, <?div>, no </div>? dang it!"
Yep. Writing code is fun with those kinds of mistakes. Even with an IDE's intellisense I screw up (depending on the IDE if you make a typo, the autohint goes away FOREVER until you backspace all teh way back to the .)

@WW Hey, random pseudo brain-flak challenge. I googled Brain-flak and followed every link I could find that seemed to be about the language. And I found this blog post. So... CMC What's the best approximation of flak(n)?
And also, can any of the examples in that post be improved?
Although now that I look closer, there are some mistakes in that post. Their small examples evaluate to a given number, but their larger numbers push a given number. And also aren't quite as optimized as they could be
We've all seen the pictures captioned "How many squares are in this image? 98% will not get this right!" Well, here's your chance to laugh at that 98%.

A rectangular block made of only 2 characters. In a general form, this is defined by m lines, each containing n characters.

Description
The task of this challenge is to devise a program or function that tracks a given object in an \$n×n\$ space.
I/O
Your program will be given 3 inputs:
n will be the size of the plane's side. (so, for \$n=5\$, your plane w...
@Adám yes, I meant match visually. I’ll edit that in to make it clear. And yes, the trace must be a single character, otherwise it would occupy 2 spaces in the plane
