> Why is Caird so Caird?

Caird is named after the artist Robert Caird. He is also the patron spirit of artists. This is why his spirit shows up here.

What does the Caird spirit look like?

In a picture he looks like a tall man with long hair wearing a white tunic(robe).

How did Caird get his powers?

Caird is very old. He got his powers from other people who came before him. He has a lot of experience.

What does his spirit do?

Caird's spirit acts like an artist. He loves to paint pictures. He also has a great sense of humor.

user

If you're 19 and >~6 months old (number depends on your definition of alive), you can already say you've been alive for multiple decades at that point

lyxal

@cairdcoinheringaahing maybe it's the fact that you can't claim to be a teenager anymore and that you're classified as a young shudders adult

@lyxal Ok boomer

Also, pretty sure "young adult" is also used to refer to teenagers

lyxal

iirc young adult is 18-25

at least that's my understanding of the term

user

idk, might be a cultural thing? Because the public libraries here classify children's/teen books as YA

lyxal

Young adult

A young adult is generally a person in the years following adolescence. Definitions and opinions on what qualifies as a young adult vary, with works such as Erik Erikson's stages of human development significantly influencing the definition of the term; generally, the term is often used to refer to adults in approximately the 20s and 30s age range. The young adult stage in human development precedes middle adulthood. == Time co-ordinates == For a variety of reasons, timelines on young adulthood cannot be exactly defined—producing different results according to the different mix of overlap...

Q: Tips for golfing in Add++

Add++ is the Language of the Month for January 2022, and so I'm asking for tips for golfing in it. Please stick to tips specific to Add++, and avoid general tips such as "remove whitespace" or "avoid comments"s

code-golf tips

caird coinheringaahing

@NewPosts Tip: Don't try to use ; in strings, cause it broke and thinks its a comment

Aww, why the downvote? :(

lyxal

not from me

user

@cairdcoinheringaahing Hmm, did someone make their parser detect whitespace and comments before passing on read characters on to other functions? (because I've certainly done that before) :P

caird coinheringaahing

 for index, line in enumerate(code):
            if comment.search(line):
                line = line.split(';')[0].strip()
                self.code[-1] += line

            else:
                line = line.split(';')[0].strip()
                self.code.append(line)

This is the comment regex

user

Beautiful

I wonder if one could abuse Add++'s parsing to make it more golfy

caird coinheringaahing

02:36

Quite possibly, it's parser is an unholy mix between regex parsing and code parsing

DLosc

@user I feel like the YA designation for books basically means "teen." It's confusing. I wouldn't consider a 15-year-old a "young adult," but I would expect them to be reading YA books.

caird coinheringaahing

oh wait theres more than one weapon?

Redwolf Programs

The plan was for you to start with the pistol and a small amount of ammo and you'd loot buildings to find better weapons, although I'm not sure if I'll ever get around to adding that much to the game

caird coinheringaahing

WAIT, you can move?! I just thought it was a "stay in place, defend yourself" kinda game :P

Redwolf Programs

Lol how did it take you this long to discover that

I suppose I should add a tutorial or something

caird coinheringaahing

Also, it's a lot easier if you just stay in place and wait for zombies to appear :P

# Cumulatively increment each integer in groups of identical integers Given a sorted array of ascending, possibly negative, possibly duplicated integers, your goal is to increment each integer cumulatively within each consecutive group. To demonstrate: [1, 1, 1, 1, 10, 10, 20, 20, 20, 30, 40, 40,...

richardec

Hi everyone! I have a pretty simple (though not too simple!) challenge, and I'd like to post it. The Sandbox post recommends "to leave your posts in the sandbox for at least several days", but I want to post it today, because Winter Bash is about to end and it'd be fun to get some hats from it. May I please get some reviews? :)

It's that one ^^ :)

DLosc

17:25

@richardec Sure, I'll take a look at it.

First thing I noticed: integers are "possibly negative," so there should be a test case that has negative integers.

user

Looks like a nice simple challenge. Is it guaranteed that the groups of integers increase? (because all your testcases have that) (I assume not though)

Also, I'm not sure "cumulative" is the right word for it, but I'm not a grammar person

Oh it's a sorted array nvm

richardec

Yes @user, the array will be pre-sorted.

@DLosc good call, I'll do that.

DLosc

I remembered answering a similar challenge before--turns out I was thinking of this, which is not a duplicate.

richardec

@user yeah, the description I had trouble with. I wanted to just write lorem ipsum for the title and run straight for the examples, but...

negative test case added

user

And maybe also a testcase where the the last number in a group goes above the first number of the next group? (e.g. [1, 1, 1, 1, 2, 2] -> [1, 2, 3, 4, 2, 3]) (i.e. the output isn't sorted)

DLosc

17:34

The negative numbers testcase does that

user

Oh right, didn't see that

richardec

added it anyway

user

I've been kinda sleepy this entire year :P

But adding another one doesn't hurt, yeah

DLosc

@richardec Yeah, you don't get rep for posts on meta (ninja'd :P)

richardec

oh, haha, sorry, I didn't even notice that was meta!! :P

user

On Meta, there's often polls and stuff, and you don't want rep from upvotes/downvotes to influence that

(I think that's the motivation?)

richardec

yeah, right, I'm familiar with meta, but I just didn't realize that it was meta at all

user

I think I see the inspiration for this challenge :P

richardec

17:38

you're sure right @user, sharp you are indeed!

user

Uh, sharp isn't something I'd call myself but thanks :P

DLosc

I think the only thing that still needs improvement is the description.

richardec

I asked that Q originally because I was working on the pb for a few days, but I hoped there was some builtin numpy func, there are so many

I've wanted to post a challenge here for a while, and I suddenly though that would make a great one

@DLosc yeah, it's not too good.

DLosc

The "group of identical integers" language ("group of identical numbers" is probably easier to read once you've established that they're integers) would be a good phrase to use in the body of the challenge.

richardec

Can you think of anything better?

Ok

DLosc

17:41

I'd probably try to split the description up into multiple sentences, too

Helps readability

richardec

Lemme work it

DLosc

(I've been writing a tutorial for the past two days, so I've got readability on the brain :P)

richardec

haha, yes, when writing stuff like this you need to pay attention! :)

@DLosc @user check it again ;)

A: Sandbox for Proposed Challenges

Unflatten groups of identical integers Given an ascending-sorted array of possibly negative, possibly duplicated integers, your goal is to increment each integer within each group of identical numbers. To demonstrate: [1, 1, 1, 1, 10, 10, 20, 20, 20, 30, 40, 40, 40, 40] should become this [1, 2,...

DLosc

It's more readable, but I don't think it says what you want it to.

"Increment each integer" sounds like "+1 to each integer," not +0, +1, +2, etc.

richardec

Yeah, that's what it seemed like as well...

Do you think "cumulatively" would be fine to use?

DLosc

17:53

Also "flatten" in the context of a list means [[1, 2], [3, [4, 5]]] -> [1, 2, 3, 4, 5], so I wouldn't use "unflatten" in the title

@richardec That doesn't communicate to me either. You're not accumulating the integers into some combined value like you do with a cumulative sum.

"Disambiguate groups of identical integers" is a bit quirky and maybe not the best word choice, but it gets closer.

richardec

Okay, good points. Let me try again.

perhaps "elucidate" or "revive"?

At least they're more eye-catching.

DLosc

@richardec Neither of those options communicate to me.

The basic idea is that you're taking each group of identical numbers and incrementing some of them until they're all different. The difficulty is communicating that 1) each group isn't in a separate sublist, and 2) there could still be cross-group duplicates in the result.

(Minor note: I think it's better to mention "possibly negative" in a separate sentence so as not to clutter up the main problem description.)

richardec

Do you think "Incrementally increment" sounds okay?

iteration 3, check again :)

DLosc

18:08

It's a bit repetitiously repetitive... but actually, in the title I like it. Alliteration is good. ^_^

richardec

haha, you're funny

DLosc

And the description is much better, too. Just a couple of typos: "by a counter, starting at 0"

richardec

I'm slightly uncomfortable with the title, but it describes it pretty well...

oops

DLosc

And don't forget to put the mention of "integers may be negative" back in somewhere

richardec

oops again
