The Nineteenth Byte

16:02

@user202729 It's not the worst challenge on main, but it could do a much better job explaining what it's asking for. I guess that the fact that there's an exhaustive list of inputs and their associated outputs the challenge technically clear, but posting a competitive answer requires a deeper understanding of the task at hand.

So for practical purposes, I'd say the challenge is unclear and should remain closed until improved.

Erik the Outgolfer

@Dennis imo it does not

is that the exact format we should output?

if not, what do the slashes mean?

there are … in a couple test cases; is it really necessary to support them? (more of a downvote reason)

user202729

Does J have user defined data structure?

FrownyFrog

@EriktheOutgolfer I did panic

The comment was very appropriate

Adám

16:18

@user202729 No, I don't think so.

@Dennis How comes I can see this chat profile but not the SO profile linked from there?

@Adám I assume the associated main account was deleted.

Adám

@Dennis But the chat account can still exist on its own?

Erik the Outgolfer

(chat is buggy :P)

Soaku

Is there any tool to check if a python format string is valid and how would it parse?

Dennis

16:23

@Adám Looks like it. I'm not a mod on SO, so I can't look into it.

Erik the Outgolfer

@Soaku what?

caird coinheringaahing

@Adám Same way that ais523 still has a chat account linked to their old PPCG account

Soaku

@EriktheOutgolfer You know, any online tool that let's me check how would Python parse a format string (ex. test {} example)

Dennis

You could either use a Python online interpreter or I don't understand the question.

Erik the Outgolfer

"parse" the string how?

Soaku

16:26

@EriktheOutgolfer You know how the string.format function work in Python right? I would want a tool that will highlight what exactly gets parsed and what does not. I got a large string and something works quite not right, when parsed by the parse library (which just does the reverse)

Erik the Outgolfer

how can formatting a string be reversed? also str.format (not string.format) isn't related to any imported stuff

Dennis

Just use f-strings.

Soaku

"test {} test" + "test blah test" = ["blah"]

@Dennis f-strings?

betseg

new in 3.6

Erik the Outgolfer

strings of the form f'...', introduced in Python 3.6

betseg

16:29

> a = 3
> print(f"a is {a}")
< a is 3

Soaku

Alright; this seems to do the trick for PyCharm. The problem is that the string is quite large, so I saved it in a file

Erik the Outgolfer

and f-strings expect you to put something in the {}

Soaku

whatever, I'll try

@EriktheOutgolfer That's good. I always fill them

Erik the Outgolfer

then how is the "test {} test" example relevant?

caird coinheringaahing

Q: Is there a way to include literal {} in a .format string? E.g. 'abc \{\} def {}'.format('1') => 'abc {} def 1' or something similar?

Soaku

16:31

@EriktheOutgolfer I just wanted to make sure you get what I want to say

Dennis

@Soaku Not in the same way. You need to provide an expression in f-strings. tio.run/##K6gsycjPM/7/…

Erik the Outgolfer

@cairdcoinheringaahing apart from print('abc {} def {}'.format('{}','1'))?

user202729

@cairdcoinheringaahing {{}}

Soaku

@Dennis Thanks for mentioning f. But about the expressions, well, I figured it out already.

Adám

@Dennis In such a state, are you able to grant explicit write access?

Dennis

@Dennis ais523 has been able to use their old account a rather long while after it was deleted...

feature-request: the ability to not have or delete chat accounts

Adám

@Dennis Looks like it. Thanks.

Dennis

@EriktheOutgolfer You can not have a chat account by never using chat. Deletion may require mod intervention.

Erik the Outgolfer

are you able to delete chat(.SE) accounts?

I would like to be able to control my own accounts though :P

Dennis

I think so. That would leave the transcript a mess though, so I don't think it should be done on request.

On second thought, I'm not sure if it would anonymize messages.

Erik the Outgolfer

17:03

I think it would, I remember that happening once

Dennis

In that case, there's a good reason to disallow it.

J. Sallé

It would probably become userXXXXX's message?

Erik the Outgolfer

yes

well, you can't just delete your account on main either, you need to contact mods 'n' staff (unless you have only posted max. 1 post)

@EriktheOutgolfer I don't think that's true. codegolf.stackexchange.com/help/deleting-account

Soaku

If anyone here uses Python parse package from PyPI, a help would be appreciated (returns null, diff's show that there is nothing that could go wrong)

Erik the Outgolfer

@Dennis apparently the recent account deletion update made that possible... -1 I don't like that idea at all

Dennis

You literally just said that you would like to be able to control [your] own accounts.

user56656

They still send you an email if you have enough reputations

And you have to wait through a 24 hour grace period

Erik the Outgolfer

I meant that I would have wanted my chat account to be able to be deleted independently of other accounts, not that I should be free to click the "RAGE QUIT" button

user56656

17:11

It's not a ragequit. You have to confirm by email and wait a full day.

Dennis

How is rage quitting from chat different than rage quitting from main? And why would SE force you to keep your account?

Erik the Outgolfer

well, if I would have wanted to delete my account because I had posted adult stuff, and there was no other pretty convincing reason stated by me, would that actually happen? also, I assume internet 101: whatever you associate your name with online can remain associated like that forever

(however I think you can disassociate posts by contacting staff)

Dennis

You can delete your account for whatever reason you'd like. The email and delay are just security features.

Woah, 7 upvotes in the sandbox... and the question doesn't even have a month.

Soaku

18:47

@cairdcoinheringaahing In one place (the 3 possible changes) you say "You may edit the behaviour of one existing command" and later you say "You may not remove or change previous commands, including the character used." So I can change it or no?

caird coinheringaahing

@Soaku Yes, must have missed that. Thanks!

Esolanging Fruit

19:00

@cairdcoinheringaahing You don't know what way this language will go, so if it were me I'd leave out the reliance on commands entirely (e.g. would adding a dictionary-compressed literal syntax be the addition of a new command?). Instead, you might reward smaller changes to the interpreter and penalize large changes to backwards compatibility in existing programs (especially changes that make programs longer).

Also, how do you prevent people from just special-casing the 20 problems?

Soaku

Grāpple

Grāpple ( GRAYP-əl) is the registered brand name for a commercially marketed brand of Fuji or Gala apple that has been soaked in a solution of methyl anthranilate and water in an attempt to make the flesh taste like a Concord grape. This solution does not add additional sugars or caloric content, nor does it affect the nutritional value of a standard apple. All ingredients are USDA and FDA approved and the process has been licensed by the Washington State Department of Agriculture. Contrary to what the name implies, it is an externally flavored fruit product, not a true hybrid of two fruits. ...

#2 reason is that C# exists

quartata

Now, yes.

Not true a decade and a half ago when we were quaking in our boots at the infiltration of Mono into the GNOME ecosystem

Pavel

Mono also sucked back then

Good thing we're talking about now

quartata

20:43

the bottom line is it's only until recently, really lining up with .NET Core, that C# was safe to use cross platform

Dennis

They bought Mono, renamed everything to make things more confusing, and now provide two completely incompatible ways of compiling C# on Linux.

quartata

it's going to take a while

you can't ride on the Java people for not being early adopters of Mono

Pavel

True

quartata

also tbh your code is probably bad if it doesn't work on .NET Core, in my eyes it's an inertia thing

also pretty sure that mono still doesn't support a good chunk of C# 6

Pavel

@quartata What are you talking about, Mono fully supports C# 7.2

Poke

from what i have read there were patented or copyrighted functions that were exposed through java apis but something something licensing

@Pavel oh, that's new

quartata

> partial support for C# 7.0

not quite finished there but

anyways I still wouldn't use C# today

no cross platform GUI

Java's STDLIB is actually really really good

Pavel

So is C#'s though

And Mono supports Windows Forms

Poke

@quartata I like the collections api

you don't get the implementation breakdowns in c# that you do in the javas

in c# you have "list"

but is that a linkedlist

an arraylist

quartata

a queue, stack, etc

Adám

@Pavel Really? TIL. All the more reason Dyalog APL should support Mono then.

Pavel

@Poke It's an ArrayList.

Poke

@Pavel yes it is

Pavel

There's also a LinkedList.

@Adám It doesn't look quite the same as on Windows. They call it GTK#.

@Poke What kinds of collections are there in Java that aren't in C#? I'm actually interested.

Poke

20:59

Speaking of data structures, here's an interesting one: en.wikipedia.org/wiki/Bloom_filter

@Pavel It's not necessarily that C# doesn't have the collection implementation; it's that you don't have the polymorphism

quartata

ConcurrentSkipListMap

Pavel

@Poke What do you mean, they all implement ICollection<T>

@quartata What even is that

quartata

a skip list

Pavel

Right. What's a skip list.

quartata

Skip list

In computer science, a skip list is a data structure that allows fast search within an ordered sequence of elements. Fast search is made possible by maintaining a linked hierarchy of subsequences, with each successive subsequence skipping over fewer elements than the previous one (see the picture below on the right). Searching starts in the sparsest subsequence until two consecutive elements have been found, one smaller and one larger than or equal to the element searched for. Via the linked hierarchy, these two elements link to elements of the next sparsest subsequence, where searching is continued...

ordered set, but better for concurrent access

Pavel

21:01

Anyway, we have cross-platform curses and console color, making C# stdlib clearly superior /s

quartata

Pretty sure there's no PriorityQueue

Poke

@Pavel that's pretty high level. in java lists and sets are both collections but they are also different interfaces

quartata

and last I checked the TreeMap equivalent sucks

of course Java is also missing multisets so not saying it's perfect

also pretty sure there's no insert-ordered dict i.e LinkedHashMap

Pavel

C# has ListDictionary

No that's something else

you'll want to use define_singleton_method also
