Q: An algorithm to find even sublime numbers

BubblerA perfect number is a positive integer whose sum of divisors (except itself) is equal to itself. E.g. 6 (1 + 2 + 3 = 6) and 28 (1 + 2 + 4 + 7 + 14 = 28) are perfect. A sublime number (OEIS A081357) is a positive integer whose count and sum of divisors (including itself) are both perfect. E.g. 12 ...

silly challenge idea "Make your language unusuable... for golfing"
in the fewest bytes, write code such that the rest of the code would have to be really long for a program to accomplish anything
in my lang (lol) i have this ++[]]][]]^{D-^):]][};{N)UO}:]E.which moves the instruction pointer to the 12288th code block
preserving all input as well
so you can still write any valid program but you have to have ~12k .s between my solution and your program
Version which only requires ~64 .s between the solution and the program: Do stuff online
^ simple addition program, input two numbers separated by newline and it will output their sum

1:59 PM
Ok nice
@ais523 You can read input as bytes
 
ais523
ais523
Jelly doesn't have a "read input as bytes" builtin
very few esolangs I've seen have both byte I/O and character I/O, most stick to one or the other
 
mousetail
mousetail
Makes sense
 
ais523
ais523
I think A Pear Tree is the only time I've even had to explicitly think about this problem (it frequently uses invalid Unicode to make the checksums work correctly)
 
mousetail
mousetail
Though IMHO byte I/O would make the most sense
With perhaps a builtin to interpret at utf-8
 
ais523
ais523
oh, and 7, that explicitly has Unicodiness options
actually it works on four main encodings (raw bytes, 7's encoding, Unicode, and US-TTY)
but US-TTY (a weird base 6 version of it) is only used internally, not in the output from the program
like, you use it to specify string literals but the output itself is in Unicode
 
mousetail
mousetail
2:06 PM
That seems sensable
 
ais523
ais523
7 is weird because I think more than half the effort put into designing the language went into the I/O :-D
 
Radvylf Programs
Radvylf Programs
@mousetail Wouldn't that add a byte to basically every single program?
 
mousetail
mousetail
IO is important. The flexible IO system on CGSE means languages can get away with not thinking about IO at all but it's very important in any other context
 
ais523
ais523
fwiw I believe that correct for a golfing language is to default to interpreting input as something vaguely JSONish, and have a way to do overrides, even though the override probably costs two bytes
 
mousetail
mousetail
@RadvylfPrograms How often do you need unicode? Very rarely. 99% of problems can be solved using just ASCII
 
ais523
ais523
2:09 PM
you need Unicode to write non-ASCII characters, which I do all the time
in particular I use endash – as part of my standard writing, dashes are a commonly used punctuation mark
 
Radvylf Programs
Radvylf Programs
@mousetail And how often do you need to work with raw bytes, where you're not allowed to just take them as a list of ints?
Golfing languages are optimized for golfing
 
ais523
ais523
no, our golfing languages are optimized for golfing on CGCC
anagol has much stricter I/O rules
 
Radvylf Programs
Radvylf Programs
@ais523 ninja'd :p
 
ais523
ais523
as do most other golf sites, I think
 
mousetail

@ais523 This, only because the IO standards here are extremely lax can languages get way with extremely limited IO options
Not nececailry a bad thing
 
Radvylf Programs
Radvylf Programs
2:11 PM
I wouldn't call most golfing languages' IO options limited
 
mousetail
mousetail
IO shouldn't really be the focus of a problem or language design
 
Radvylf Programs
Radvylf Programs
You can input any value which the language can understand using ASCII
 
ais523
ais523
Jelly does seem to have made some attempt at optimizing for stricter I/O rules, with single-byte builtins for splitting and joining on spaces and newlines
@RadvylfPrograms this is true, but then you need a separate program to do encoding/decoding, and also to write an encoder/decoder inside the program itself, so it makes the language a lot less usable
 
Radvylf Programs
Radvylf Programs
@ais523 Never even thought of those in the context of strict I/O honestly
They're just useful in general
 
ais523
ais523
many of my languages only allow digits and newlines in I/O
if you need something else you interpret it as a list of character codes
but, those languages aren't designed for golfing
 
Radvylf Programs
Radvylf Programs
2:13 PM
FWIW I think the specifics of how I/O is formatted should be done via flags
4
 
mousetail
mousetail
Yep that would be fine
 
Radvylf Programs
Radvylf Programs
E.g., there should be a flag which just takes all of the input and passes it as a string
 
mousetail
mousetail
Better flags than environment variables
 
ais523
ais523
I can see an argument for that – although for anagol and the like, there should be some way to embed the flags into the program
 
Radvylf Programs
Radvylf Programs
And one which does the normal JSON-y parsing for more varied input
 
Unrelated String
Unrelated String
2:14 PM
@RadvylfPrograms split/join on newlines is not too big in actual golfed code on a site where i/o defaults permit lists of lines
 
Radvylf Programs
Radvylf Programs
@UnrelatedString For things like ASCII art though, a list of lines is pretty cheaty
 
ais523
ais523
on anagol, specifying flags in Perl has an 8-byte penalty + 1 byte per flag, and yet it's still often worth paying
 
Radvylf Programs
Radvylf Programs
Even if it's technically allowed
 
Unrelated String
Unrelated String
@ais523 i actually just thought of something like this when you mentioned anagol--ship the language with one flag, on by default there perhaps, that enables encoding other flags into the program
 
Radvylf Programs
Radvylf Programs
Most flags are there for like, how the program itself is read or encoded though
 
ais523
ais523
2:16 PM
@UnrelatedString yes – any language with flags should have a "look at the program for the flags" option, + some encoding that lets the flags go into the program fairly seamlessly
 
Radvylf Programs
Radvylf Programs
I don't think that really makes sense for anything but Vyxal/Japt-style cheaty flags
 
ais523
ais523
can go in the first byte of the program, for example
 
Radvylf Programs
Radvylf Programs
That adds a byte penalty to every single program
That would be ridiculous
(For a golfing language, at least)
 
Unrelated String
Unrelated String
better than the actual flag penalty :P
 
mousetail
mousetail
Use the first bit of the program instead
 
ais523
ais523
2:17 PM
@RadvylfPrograms Perl has flags like -p which contain a lot of functionality and look like a Vyxal-style cheat, but are unlikely to have been designed for golfing (although IIRC Perl invented golfing, so it's possible it was there for golfing purposes)
 
mousetail
mousetail
1/8th byte penalty
 
ais523
ais523
I do, however, use -p quite regularly when writing Perl one-liners that aren't meant to be golfed
 
Unrelated String
Unrelated String
considering perl's aptitude for one-liner utilities i imagine there is sort of a convergence there
common patterns of how you'd use it generalize
 
Radvylf Programs
Radvylf Programs
@ais523 Isn't that an example supporting my side?
 
ais523
ais523
@RadvylfPrograms I'm not sure I agree – almost every problem needs I/O so making it a mandatory part of the program isn't that weird if you have an inflexible-I/O situation
 
Radvylf Programs
Radvylf Programs
2:18 PM
Perl went with a flag for that, because a flag for that makes more sense than specifying it in the program itself
 
ais523
ais523
I think Perl went with a flag for that because it was inspired by sed, which also has a flag for that
 
Radvylf Programs
Radvylf Programs
@ais523 I don't really know what that means
 
ais523
ais523
although in the case of sed, it's the default behaviour and the flag is to turn it off
 
Radvylf Programs
Radvylf Programs
Implicit I/O has been a thing in golfing languages for years, having to add even a single byte of overhead to a golfing language would make it enormously uncompetitive given than answers are typically just a couple of bytes
 
ais523
ais523
@RadvylfPrograms say you're trying to use a programming language practically, not just for pure golfing – anything you do will need I/O and the format won't always be the same, so it's probably terser to always specify it in the program than to have a default (that needs extra bytes to override)
it would make it uncompetitive at CGCC and only for problems where flexible I/O solves all the I/O problems
it would make it more competitive at anagol, where you often need a custom I/O routine for every single task
 
Radvylf Programs
Radvylf Programs
2:21 PM
And strict I/O sort of falls into two types: I/O that's strict technically (like, requiring input from STDIN), or strict format-wise (e.g., a string, instead of array of lines). The first would make way more sense as flags and isn't at all cheaty, while the second is already possible to encode into programs and no flags are needed for that at all.
 
ais523
ais523
yes, but having a special-case DSL for it saves a lot of bytes
 
Radvylf Programs
Radvylf Programs
I'm not sure which of the two types of strictness you're talking about
 
ais523
ais523
because commands that are good for encoding I/O are generally bad for anything else, so you don't want them cluttering up the "main part" of your builtins
 
Radvylf Programs
Radvylf Programs
For the first one, if you're using it practically, it makes way more sense to use a flag
 
ais523
ais523
mostly the latter
 
mousetail
mousetail
2:22 PM
You are suggesting having some commands only available as the first byte right?
 
ais523
ais523
or first run of bytes – you could make it self-delimiting
 
Unrelated String
Unrelated String
^
 
Radvylf Programs
Radvylf Programs
Yeah, that makes more sense.
 
mousetail
mousetail
Then those byte values could be replaced by others later, maybe something that would make no sense at the beginning
 
ais523
ais523
and those commands would be specialised for changing the I/O encoding
 
Radvylf Programs
Radvylf Programs
2:23 PM
Stuff like file vs. STDIN vs. args and stuff should still be flags IMO, but that sort of thing would be cool (you'd probably want a similar thing for the last byte too)
 
mousetail
mousetail
I think in general golfing languages can do more with changing behavior based on neighboring characters and location in the program
 
ais523
ais523
problems like "write an integer as 6 hexadecimal digits" are actually quite difficult to solve tersely in Jelly, and normally come up only in I/O
 
Radvylf Programs
Radvylf Programs
I think that's mostly just due to its lack of triads
It'd be like, two or three bytes if there was a string padding atom
 
ais523
ais523
I think the shortest solution to that I found was to add 2²⁴, express as base 16, index into a list of hexadecimal digits and delete the first element
it'd be more than three even with a string padding atom
you need the atom, two arguments, and a separator between the arguments
 
Radvylf Programs
Radvylf Programs
You could also concat a string of six zeroes with the hex representation, and slice the last six chars, probably longer tho
 
ais523
ais523
2:26 PM
although, if you allocate a byte as the separator, you now have an entire 256 triads that don't clash with anything else
@RadvylfPrograms or prepend a zero while the length of the string is less than 6, that's an algorithm I hadn't thought of last time I tried and might be shorter
oh, the other reason for all this is that except in I/O, you nearly always want little-endian base conversions, but people expect big-endian for I/O
I've lost count of the number of bytes I've lost over the years to base conditions being big-endian by default
 
Radvylf Programs
Radvylf Programs
@ais523 Oh, true. Probably four bytes: hexadecimal pad 0 6 (in some order), maybe five depending on the parsing
@ais523 Big endian would be 1a for 26, right?
I've never seen little endian base conversion if so
 
ais523
ais523
pad 0 6 has to be pad 0 separator 6 unless you're doing something Brachylog-style where constant arguments to commands have their own character set
@RadvylfPrograms right ­– little endian just reverses the string, a1 for 26 in hex
it is most useful when considering the string as a list of digits, so [10, 1] for 26 in hex
 
Radvylf Programs
Radvylf Programs
I don't know much about Jelly's parsing, but it could always be 0 pad 6, with the assumption that the third argument would typically be implciit
 
ais523
ais523
because if you convert a range of numbers which have different numbers of digits, the digits with the same place-value are in the same position of the array
 
Unrelated String
Unrelated String
@ais523 not related to enforcing 6 digit width but i was about to say "wait can't you just use ṃ instead of separate base conversion and indexing" then remembered that ØH is 0123456789ABCDEF but ṃ uses 1-indexing
 
ais523
ais523
2:30 PM
@UnrelatedString oh wow, I forgot that :-D
0-indexing and 1-indexing both have their own advantages and disadvantages – I think 0-indexing is usually better if you have some falsey sentinel value and some way to make a truthy 0
 
Unrelated String
Unrelated String
yeah
 
ais523
ais523
but 1-indexing is simpler because you can use 0 as the "not found" sentinel
 
Unrelated String
Unrelated String
1-indexing is useful mostly for the falsiness of 0
 
Radvylf Programs
Radvylf Programs
<aside>I think gluing together single digits into multiple-digit numbers doesn't make any sense in modern golfing languages. x26 should be x 2 6, not x 26, and even more so with leading zeroes
 
Unrelated String
Unrelated String
and in the context of jelly that definitely wins but that is no reason for ṃ not to be inconsistent for the sake of usefulness
 
Radvylf Programs
Radvylf Programs
2:32 PM
Pretty much all modern golfing languages have integer compression already, and it's bound to be more effective than typing out the number whole
 
ais523
ais523
@RadvylfPrograms I agree – have constants for 0 through 10, plus one or more leading bytes for "this is a multiple-byte number" and then use a much terser base than decimal to specify what it is
 
Unrelated String
Unrelated String
decimal literals can be useful for hacky transform-eval solutions but at that point you may as well just design a separate mini-language for that so you don't sacrifice anything for everything else
 
ais523
ais523
that said, in one language I was working on, I did use digit-gluing (in base 11) for numbers of up to three characters in length, but that's because the character set was unusually small
 
Radvylf Programs
Radvylf Programs
@ais523 Yep. That's the approach that I'd use (maybe with a few more single byte constants), and Jelly even already has an integer compression thingy for two digits
 
ais523
ais523
one of ⁽ or ⁾, I can't remember which
I have memorized how to type almost every character in Jelly's character set – I forget which ones I still have to copy-paste

if you haven't rebound caps lock, like I have, holding right shift and tapping right alt works as a substitute

I'm thinking back to the earliest programming languages
 
Radvylf Programs
Radvylf Programs
And IMO our rules should be written to make golfing as fun as possible, without that compromising how fun some other aspect is (e.g., overly loose I/O)
 
ais523
ais523
2:44 PM
where things like file I/O were defined very differently from today – normally the program would say things like "output to file 4" and what "file 4" was and its format would be defined separately from the program itself
I think CGCC-style golfing languages may be a revival of that
 
Radvylf Programs
Radvylf Programs
Which, IMO, our I/O is a bit of a mess. Our standard I/O is way too loose for most languages, while still being to restrictive for others
 
ais523
ais523
being allowed to I/O numbers by char code is a lifesaver for many esolangs
 
Radvylf Programs
Radvylf Programs
I don't think JS or Jelly should get to output a list of lines when the challenge wants ASCII art. I don't think JS or Python should be able to take input via variables, but languages which have those and literally no other I/O shouldn't have that hard ban.
 
ais523
ais523
but yes, one big problem with the I/O defaults post is that it assumes that languages have relatively standard concepts like numbers and lists
 
Radvylf Programs
Radvylf Programs
^
I/O is going to be language-specific, no set of rules can make sense for every language.
 
ais523
ais523
2:46 PM
if the language has no built-in concept of what a number is, you generally have to write full programs because none of the function methods work
 
Radvylf Programs
Radvylf Programs
I think there should be a set of I/O guidelines, which certain classes of languages are strongly advised to follow, but we should use the same vague "do what you want within reason" thing as we do with flags
 
ais523
ais523
(with the possible exception of entirely string-based languages, like Retina and yacc; those can take numbers as ASCII representations of their digits, so you can write functions)
but take the example of something like Incident – data can't really move through the program there, it stays in one place permanently
so although it has functions, you can't give them numbers as arguments without defining a complicated chain of callbacks between the function and whatever it is that stores the number
and when you do set up a method of providing arguments like that, the function is no longer reusable because it can't tell where it was called from and thus doesn't know who to ask
you'd probably want to standardise numeric I/O as something like having two functions, where calling the function on a number n is done by calling the first function n times then the second function once
(come to think of it, this is how input is done in 7, which doesn't have numbers in the usual sense – input is a control flow builtin, which loops a number of times equal to the input + 1, EOF gives you a 0-iteration loop)

I often wonder about how far I can push the I/O defaults when I solve challenges in Acc!!. It would be most convenient to use unary (and that's the use case the language was designed for). But it is possible to do decimal I/O; it's just really clunky and annoying to write decimal I/O routines every time.

Q: Carry-less sum given a base b

loopy waltGiven a list of positive integers \$\mathcal I=I_1,I_2,I_3,...,I_n\$ and a base \$b>1\$ return their "carry-less sum", i.e. represent \$\mathcal I\$ in base \$b\$ and sum digit-by-digit discarding carry. Worked example: I = 13, 2, 9; b = 3 In base 3: 111 + 2 + 100 ----- = 210 and back ...

@DLosc honestly i think unary would be reasonable then

Sure, but can it be implemented in a lisplike implemented in itself? :p
Can't go too deeply tho or you'll end up in an xkcd 1764 situation

Is there a name for a data structure where you have a bunch of blocks of data, where you keep a pointer to the next unused block, and when a block is done being used, you move the pointer to that block and replace it with a pointer to that block?
Basically creating a stack with a linked list that keeps track of unused blocks, without any memory overhead (aside from a single pointer)

"you move the pointer to that block and replace it with a pointer to that block" - what?
Do you mean, replace the contents of the recently garbage-collected block with a pointer to the previous head of the linked list of unused blocks?
