@Zacharý what's so surprising about that? TCL does that too :P

Zacharý

@ASCII-only This is what's weird

Only the literal [1] can get treated as a string.

ASCII-only

12:53 AM

you're passing it a char array...

wait...

@Zacharý hmm

Zacharý

Like I said ... weird.

Q: Can we assume typed inputs?

For some languages with a static type system the compiler is able to infer the types, however sometimes there's ambiguity (even with input) unless the user gives the type manually: Motivation 1: Haskell Consider the following Haskell example: f xs = do x <-randomRIO (toEnum 0, toEnum 1) --...

@Zacharý link

@Zacharý no?

@Zacharý now this is weird

Zacharý

No, I completely understand that one. D's string type is actually immutable(char)[]. And char cannot be casted to immutable(char)

ASCII-only

well actually it isn't

Zacharý

12:57 AM

@ASCII-only link then?

ASCII-only

@Zacharý but a char literal is immutable(char)

@Zacharý sorry it was as a reply to my previous message

Zacharý

Ah.

@ASCII-only And there's no dchar literals. That got me a few times when I was writing 'd'd for RAD.

quartata

@NewMetaPosts pretty sure this is a duplicate

Oh no ... segmentation fault. There are no pointers in my code.

⌿ and ⍀ are done.

quartata

1:52 AM

@Zacharý how is it possible that there are no pointers in your code

id be very interested to see this

Zacharý

@quartata Because D is an awesome language.

Here, in the /dev folder

quartata

put on a blindfold and clicked on a file at random

i saw a pointer

id like my $20 back

Zacharý

Which one?

quartata

Segment[]

didnt read past the type. started foaming at the mouth.

screaming

Zacharý

@quartata That ain't a pointer in D my friend.

quartata

1:56 AM

waking up the universe

@Zacharý are you telling me its copied

because if so i think i might have found, you"re performance issue

Zacharý

@quartata The pointer would be Segment*. Segment[] is like std::vector<Segment>

quartata

still wrapped

Zacharý

@quartata My performance issue is the O(n^2) parser and tokenizer.

quartata

unless it doesnt move and actually copies the whole vector

Zacharý

@quartata I think it moves.

quartata

1:58 AM

which sounds like something rust would do

@Zacharý then congregations. you have a pointer

Zacharý

@quartata I meant no explicit pointers. No T* anywhere.

quartata

Oh well

i dont do that

ASCII-only

@Zacharý please don't scan postfixes then

std::shared_ptr<std::weak_ptr<std::shared_ptr<T>>

@ASCII-only Once it's on TIO, that'll be next on the list.

@Zacharý ok good :P

quartata

sometimes i wish i had a haskell compiler.

Pavel

2:05 AM

@quartata brew install ghc or whatever

quartata

ghc is bigger than 2 GB, the butterflies cant address that far. so instead im just praying that a piece of toast falls from the ceiling with a copy on a hard disk

Pavel

@quartata Has a similar event ever occured in the past?

quartata

...it wasnt a joke?

@Pavel yes. this is how i got a C compiler Basically

pure chance, and yet it might just save us yet

now thats the real joke

Pavel

@quartata Lucky. I had to scavenge my C compiler from the remains of a C++ compiler being torn apart by a vicious javascript interpreter.

quartata

this is giving me bad memories.

people would tear apart real people. just for a place to stand. some shade.

anyways. if anyone can find me a smaller Haskell compiler, that would be more feasible than my toast idea.

Q: Iterate string instead of integer

This is a code golf version of a similar question I asked on stack earlier but thought it'd be a good code-golf question. Have a 10-length string starting from 0000000000 Iterate through till you get to 0000000009 Then start using letters in place to get 36 total iterators 000000000a . ....

@JungHwanMin Would making it shorter than 42 make it less impressive :P

@Mr.Xcoder Looks like that it works.

Yes it works. Pyth = shorthand is more general than Python's. (of course)

@quartata O_o why do you need to dissect a cactus

lol

@Downgoat :/ perhaps he has to get water, as the post above implies?

@quartata (this one)

quartata

yeah, yeah

every bit counts

lol

I can't still understand what's going on o_o

quartata

think im tripping after drinking this cactus water actually

dont do this kids

lol

hmm

strange

quartata

4:10 AM

never mind it was just indigestion from all the fried lychee nuts i ate

Downgoat

@quartata oh in that case give it lots of love and eventually the cactus will open its heart and give you its water

lol

github pages doesn't want to update itself o_o

quartata

@Downgoat souds like that takes a while

not sure i have the Time

lol

Is this a situation when you cant stick a straw in

quartata

thats not a bad idea

lets see here

hm. need a metal straw.

oh ok apparently while i spent 3 hours dicking around with cactuses someone actually found another acquifer

lol

4:16 AM

Or you can stick a metal pipe-thingy (perhaps a water tap) in

quartata

sometimes i wonder why the embassy pays me, i dont think they have any idea what i actually do

perhaps its better that way

Are we in a philosophical talk

quartata

we all are in a philosophical talk, every night of our lives

thats just how it works

i don't make the rules

Locate Substring This is not a challenge yet, just a place to write down an idea. Given some finite binary string \$S\$, we can try to find the minimal length \$n \in \mathbb N\$ such that we can uniquely locate each contiguous substring \$ T \$ of \$ S \$ that has length \$ n \$. Example Let \$ S = 01000110 \$. Then surely \$ n > 1\$. But we also immediately see that \$ n > 2\$ b…

Assume that the method of generating the hidden test-cases is known. (for example: a list of 5000 uniformly random integers in range [1..1000]) Reasons why hidden test cases should be allowed (that I can think of): Guaranteed to prevent hard-coding (assume that there are sufficiently many poss...

            "zwierzę":         "pet=items.Item",
            "zaklęcia":        "spells=list"

(yeah, totally bad practise, it has to read a human-readable format and be future-proof)

user202729

Hm...

Ah.

eval is for expression. Use exec.

Soaku

ahh... makes sense. Never used those methods in Python, I avoid them

Works, thanks

user202729

Still, you should do a = { 'key' : ('field name', int) }, then

self.__dict__[a[key][0]] = a[key][1](val) (if this is more readable...?)

Avoid the exec.

oh my god... In the script above, I call a function, it finds a list of pairs with regex, starts a loop and then passes them to a different function. When the program executes line by line in a debugger, it reaches the loop and then suddenly the function stops, like if there was a return inside, but there is only an assignment...

What the frick? It was caused by a call to .rtrim(":") on one of the groups...
