0:37 Frozenlock: hmm... clojars no longer accepts public keys? When I go in 'profile' I can only update my email and password :-/

0:59 Seems it's no longer required.

5:23 narwhal01: hi guys

5:26 what is the best way to do this: if i have list of hashes as [{:k "a"} {:k "b"} {:k "c"} {:k "m"} {:k "c"} {:k "b"}], what is the best way to select consecutive hashes based on one schema "abc" , or "mc", or whatever "abc" refer all hashes with :k equal a then b then c consecutively

5:27 the provided schema should be generic

5:27 is there a good solution of this?

5:30 ridcully: ztellman/automat has a similar example in its readme

5:33 narwhal01: ridcully, what exactly? in the page?

5:33 https://github.com/ztellman/automat

5:34 ridcully: the "short example"

6:17 narwhal01: ridcully, can you help me out to use automat to apply on my example?

6:30 ridcully: narwhal01: most likely not. i only remembered it from reading some time ago

6:30 ,(let [m [{:k "a"} {:k "b"} {:k "c"} {:k "m"} {:k "c"} {:k "b"}] s "abc" l (count s)] (filter #(= s (apply str (map :k %))) (partition l 1 m)))

6:31 clojurebot: (({:k "a"} {:k "b"} {:k "c"}))

6:57 narwhal01: ,(let [m [{:k "aa"} {:k "bb"} {:k "cc"} {:k "mm"} {:k "cc"} {:k "bb"}] s "aabbcc" l (count s)] (filter #(= s (apply str (map :k %))) (partition l 1 m)))

6:57 clojurebot: ()

7:41 l1x: hey guys, is there a way to do a (def something JavaClass.) and (.method1 something) and than (.metehod2 something) in clojure somehow nicely? I know of the -> macro but it does not apply here because the methods do not return the changed object

7:42 opqdonut: doto

7:42 luma: (doto (JavaClass.) .method1 .method2)

8:02 Empperi: ,(doto (java.util.HashMap.) (.put "foo" "bar") (.put "bar" "foobar"))

8:02 clojurebot: {"foo" "bar", "bar" "foobar"}

8:02 Empperi: a more complete example

8:21 ashnur: any good talk/video on persistend data structures, how they are implemented? something that's not a MIT lecture :D

8:22 l1x: opqdonut & luma thx! Empperi too :)

8:27 mokuso: what's wrong with MIT lectures? xD

8:27 ashnur: nothing in particular, but i just want to show someone a link where they can get a feel on how this works

8:31 i remember seeing a video where someone explained this in a few minutes, why it works and how it works

8:59 miguelsm: ashnur: https://youtu.be/mS264h8KGwk?t=8m40s

12:17 jeaye: https://news.ycombinator.com/item?id=11240004 written in clojure/script

12:46 sdegutis: I wrote a blog post for you guys http://sdegutis.github.io/2016-03-04/clojure-naming-best-practices/

12:55 mavbozo: sdegutis, thank you

12:56 sdegutis: mavbozo: I truly hope you find it helpful, because I spent like 20 minutes trying to get that CSS to not be completely awful.

12:56 MJB47: what about :use :only

12:59 sdegutis: MJB47: That's the exact same thing as (:require :refer) and has all the same drawbacks.

13:00 amalloy: sdegutis: missiona ccomplished: "not completely awful" is how i would describe that CSS

13:00 sdegutis: amalloy: yesssss

13:06 Is it possible using some function in clojure.core to create a function that ignores its parameter(s) and returns a constant value, much like (constantly) but allowing argument(s) to be passed?

13:09 tolstoy: (fn [& args] 42)?

13:11 justin_smith: sdegutis: constantly

13:11 ,((constantly 42) :a :b :c :d)

13:11 clojurebot: 42

13:11 justin_smith: :b8

13:11 ddellacosta: sdegutis: I'm not entirely clear what you're asking for--if you want to return the argument passed, the constantly; if you want the arg passed in, then identity is it

13:11 then* constantly

13:11 reverse what I said, d'oh

13:12 * ddellacosta needs more coffee

13:14 sdegutis: Huh. Wow, yeah, I was misusing constantly.

13:14 I was stupidly doing something like (#(constantly 1) 2 3) or something.

13:14 Turns out constantly is what I always wanted.

13:15 Thanks everyone.

13:17 justin_smith: sdegutis: alternatively you could do ((#(constantly 1)) 2 3) but that would be silly

13:18 sdegutis: justin_smith: Yes. Yes it would.

13:39 Hi.

13:58 Is there a shortcut for this pattern? (->> (for [x xs] (str (f x))) (apply str))

13:59 I find it very ugly and I hate its stupid face. Thanks in advance.

14:01 rhg135: (apply str (map f xs)) I think

14:09 sdegutis: rhg135: Hmm sorry, I should have done dot-dot-dot instead.

14:09 Is there a shortcut for this pattern? (->> (for [x xs] (str ...)) (apply str))

14:10 rhg135: (apply str (map (comp str ...) xs)

14:11 amalloy: sdegutis: i think the shortcut is to just omit the inner str call

14:11 sdegutis: amalloy: Hmm.

14:12 rhg135: that

14:12 amalloy: since (str 1 2) is the same as (str (str 1) (str 2))

14:12 sdegutis: I guess I was looking for something like (for-str [x xs] ...)

14:13 I'd like to create a giant string based on transforming some Clojure data structures, and having several (apply str) in the middle of other (apply str) feels clunky.

14:13 One alternative is to use a more "proper" templating library, like clostache.

14:13 But I feel like there's got to be something that's more friendly to Clojure transformations, considering Clojure already is its own kind of DSL as opposed to moustache.

14:14 Rather than {{#foo}}{{bar}}{{/foo}} I'd like to have (for [foo foos] (:bar foo)) or something.

14:14 But with even one level of nesting, that gets real ugly real quick.

14:14 amalloy: sdegutis: i mean, you could like...omit all of the apply str calls, and return a list of things you want the outermost str to apply to

14:14 just make sure not to create the nesting

14:15 sdegutis: Or maybe use mapcat.

14:15 So I guess I want something like for but with mapcat? Hmm.

14:15 Which for already kind of has built-in.

14:15 amalloy: for is already like for but with mapcat

14:15 sdegutis: Right.

14:16 If I return a vector, it flattens it for me.

14:16 Wait, that doesn't make sense.

14:16 ,(for [a (rest (range 5))] [a a a])

14:17 clojurebot: ([1 1 1] [2 2 2] [3 3 3] [4 4 4])

14:17 sdegutis: Hmm. What's that behavior I'm thinking of?

14:17 Is it not in (for)?

14:19 justin_smith: ,(for [a (rest (range 5)) b [a a a]] b)

14:19 clojurebot: (1 1 1 2 2 ...)

14:20 amalloy: sdegutis: (for [x xs, r (f x)] r) is the same as (mapcat f xs)

14:20 in that simple scenario of course it's nicer to use mapcat, but if you're doing anything more involved for can be pretty good

14:20 sdegutis: I see.

14:21 justin_smith: But I vaguely remember some weird behavior where some type of mapping/transforming function treats a returned list as a special thing and "flattens" the results by removing that list, making you have to do something like [[x]] if you really wanted to return [x].

14:22 TMA: ,(for [a (rest (range 5))] (let [r [a a a]] r))

14:22 clojurebot: ([1 1 1] [2 2 2] [3 3 3] [4 4 4])

14:22 TMA: ,(for [a (rest (range 5)) b [a a a]] [b])

14:22 clojurebot: ([1] [1] [1] [2] [2] ...)

14:23 amalloy: sdegutis: i can't think of any commonly-used functions that behave that way

14:24 TMA: mapcat is a wrong simile -- (for [v1 ... v2 ...] ...) is a nested loop producing one element of the resulting sequence per iteration

14:25 ,(for [a (range 5) b (range a)] b)

14:25 clojurebot: (0 0 1 0 1 ...)

14:26 sdegutis: I'm sure I'm not crazy.. what could this mysterious function be?

14:26 TMA: ,(for [a (rest (range 5)) b (range a)] b)

14:26 clojurebot: (0 0 1 0 1 ...)

14:27 sdegutis: The more I think about it, the more I think it was mapcat.

14:28 No wait, that can't be it. That's expected, whereas this was unexpected.

14:30 amalloy: TMA: are you saying that mapcat is a bad way to explain what for is doing?

14:31 TMA: amalloy: yes. #'for can be explained via mapcat, but the explanation using mapcat is needlesly complex and not general enough

14:35 first: (for [x xs] form) is (map (fn [x] form) xs); second: (for [x xs y ys ...] form is (apply concat (for [x xs] (for [y ys ...] form))) third: reorder the resulting form to use mapcat

14:36 sdegutis: Okay just searched the stdlib, nothing seems like what I'm thinking of.

14:36 Maybe I dreamed it up?

14:36 amalloy: cfleming: are you around? i can't figure out how to activate my cursive license. enabling cursive and restarting cursive just causes it to be re-disabled, rather than popping up the "show me your papers" menu i would hope for

14:37 er, restarting intellij, not cursive, of course

14:38 cfleming: well, never mind. just uninstalled cursive entirely, then reinstalled it; then did that a second time, and now it's asking for a license again

14:38 ridcully: have you tried turning it off and on again?

14:38 amalloy: not enough times, it seems

14:39 ridcully: in that case the advice from beavis and butthead applies: have you tried to set it on fire?

14:50 sdegutis: Two more blog posts for your reading pleasure: http://sdegutis.github.io/2016-03-07/simple-clojure-render-function/ and http://sdegutis.github.io/2016-03-07/simple-clojure-md5-function/

14:54 wink: sdegutis: could be parametrized even easier: https://github.com/winks/multiplex/blob/599a87b27dfdb937c519e0b9a2c1f251e998237f/src/multiplex/util.clj#L170

14:55 sdegutis: wink: hmm, I want to believe, but only TimMc and justin_smith and amalloy understood how the function on my blog works, so..

14:56 wink: yours has more format magic :P

15:02 sdegutis: Yay!

15:03 wink: sdegutis: may I suggest a link back to / - because the explanation that all the posts are indeed at the bottom is only written there :P

15:03 sdegutis: wink: Maybe just a header on that posts list will suffice.

15:03 "All posts, newest to oldest."

15:03 wink: plus only some of your footers link to github. but I like the colorscheme :P

15:05 amalloy: sdegutis: (format "" (name k))? what in the world?

15:09 TimMc: sdegutis: You've got some bug in your blog software, your variable reference syntax is being eaten.

15:16 wink: unescaped {? :P

15:17 sdegutis: amalloy: um, cuz of this

15:17 ,(format "{{%s}}" :foo)

15:17 clojurebot: "{{:foo}}"

15:17 sdegutis: Oh yeah, wow, you're right TimMc and wink.

15:17 * sdegutis fixes

15:19 sdegutis: fricken Jekyll

15:21 ok fixed sorry bout that

15:23 TimMc: sdegutis: It's almost as if rendering and templating are hard and should not be oversimplified.

15:24 sdegutis: TimMc: oh?

15:24 TimMc: Which is to say: Careful with that "don’t need any escaping behavior or special logic".

15:24 sdegutis: TimMc: there's a time and place for everything

15:25 TimMc: sometimes escaping is not a need

15:25 TimMc: It never is, at the beginning.

15:25 And that's how you get in trouble.

15:25 sdegutis: TimMc: i like your style

15:25 TimMc: me too

15:30 sdegutis: TimMc: +1

15:40 Hi.

15:40 wink: better?

15:42 wink: TimMc: to be fair it is kinda meta to blog about it with the same syntax that gets eaten by the blog software :P

15:42 sdegutis: looks good

15:42 Shadizzle: hiredman: I was told that I should consult with you about getting clojurebot to log into #clojure-beginners. Not a big deal obviously, but I think it would nice if there's no significant reason for him not to be logged into that channel. I'm new to clojure and this channel in any case.

15:42 TimMc: wink: I think there's a problem with your md-hash...

15:42 wink: TimMc: it passed my tests so far

15:43 but the other version with UTF-8 intrigued me :P

15:43 maybe time for MOAR TESTS

15:43 hiredman: Shadizzle: I'll see what I can do

15:45 I think clojurebot would respone to a irc invite, but freenode only lets ops do that

15:45 Shadizzle: hiredman: Cheers, thank you.

15:45 TimMc: wink: Try it with "Hello, world."

15:46 wink: nice, long string :P

15:46 it's missing a leading 0

15:46 TimMc: yup

15:46 wink: works with "hello" for example

15:46 thanks.

15:47 I still prefer the parametrization

15:48 sdegutis: wink: no he meant the solution itself was dangerous since it discounted the importance of escaping

15:48 wink: so he hates my (defn (render s m) ...) function

15:48 validly, of course

15:48 wink: sdegutis: well, it's never "easy"

15:48 sdegutis: agreed, life is hard

15:48 wink: but one can live without a library

15:48 TimMc: funny thing, I'm not even using the code :)

15:49 sdegutis: wink: btw regarding your md5 thing, i remember our version failed some test-cases where the first number was "1" or somtehing like that, i forget what exactly

15:49 * sdegutis digs up IRC logs via lazybot or something

15:53 sdegutis: Ahh yes http://clojure-log.n01se.net/date/2015-12-15.html

15:53 TimMc: haha

15:53 sdegutis: "TimMc: you'll be receiving our bill in 2-3 business days" crap I never received that

15:53 oh well, the quarter passed so im in the clear now

15:53 TimMc: well now there's interest on it

15:54 sdegutis: no thats not how it works. if you forget to bill past a certain date, its free.

15:55 AndreasO: Hello!

15:58 sdegutis: Hello!

16:00 I wish I could search #clojure logs (via http://clojure-log.n01se.net/) for "[[" because I'm sure that would turn up that mysterious function I'm thinking of.

16:03 TimMc: sdegutis: Who posted it?

16:04 sdegutis: me probably

16:04 AndreasO: A seesaw question. How do I address the root widget ? I'm using config! with select to change a canvas .

16:08 sdegutis: Is Seesaw still in active development?

16:10 AndreasO: sdegutis: last change was 20 days ago

16:10 sdegutis: Cool.

16:13 neoncontrails: You made it, AndreasO. :-)

16:13 AndreasO: neoncontrails: ?

16:14 neoncontrails: We were just chatting on the facebook group

16:14 AndreasO: Ahh

16:15 audrius: what is the URL for facebook goup?

16:15 AndreasO: https://www.facebook.com/groups/clojure/

16:16 audrius: dank

16:18 AndreasO: audrius: varsegod!

16:19 neoncontrails: so what now?

16:20 neoncontrails: ¯\_(ツ)_/¯

16:20 AndreasO: 22:04 AndreasO A seesaw question. How do I address the root widget ? I'm using config! with select to change a canvas .

16:20 TimMc: sdegutis: I can try my logs of this room, which are about 140 MB uncompressed.

16:20 sdegutis: wow

16:20 TimMc: wanna just send them to me?

16:20 TimMc: ha

16:20 sdegutis: TimMc: dont trouble yourself over searching for it, its mostly pointless

16:20 TimMc: I'd have to think about that, but maybe.

16:20 sdegutis: TimMc: but thanks

16:21 neoncontrails: AndreasO: answers sometimes come in an asynchronous fashion

16:22 TimMc: sdegutis: Too much chaff for "[["

16:22 amalloy: fwiw my personal #clojure logs, a paltry 54MB, have 2008 instances of [[

16:22 AndreasO: How can I find out if an answer has come?

16:22 sdegutis: TimMc: thought so

16:23 amalloy: when did you start keeping those logs? since about 2008?

16:23 neoncontrails: AndreasO: But in general posting a pastebin or some sort of live REPL of the issue is a good idea. Highly conducive to receiving help

16:24 amalloy: hm, i actually only have logs on this computer going back to 2014

16:24 http://malloys.org/~akm/sdegutis.html -- lines matching /sdegutis.*\[\[/

16:25 TimMc: Mine start in 2011, but I'm sure there are gaps near the beginning.

16:25 sdegutis: amalloy: oh wow smart idea

16:26 haha! oh man. i was just about to say "look! the last line is the one i was looking for!"

16:26 amalloy: i *should* have logs going back to like 2010. i wonder where they went

16:26 sdegutis: but yeah, i cant find it

16:26 and it was definitely since 2014

16:27 AndreasO: neoncontrails: strange thing irc, like standing in a crowded room speaking and hoping for someone to respond.

16:27 sdegutis: thanks anyway amalloy and TimMc

16:28 amalloy: AndreasO: indeed. you probably just want to repeat your question every hour or so and hope someone who knows seesaw happens by. or you could ask on stackoverflow

16:28 neoncontrails: AndreasO: third-party libraries = smaller user community = fewer people may be able to help you

16:28 TimMc: AndreasO: Can be like that, yeah. More like a room of animated mannequins, and you're never sure which ones are "alive" at the moment. :-P

16:29 ridcully: if some java api takes varargs (e.g. void something(Class x, Something... ss)), am i right to assume, that i have to provide the `ss` there (e.g. with into-array) while java itself seems to allow for nothing?

16:29 TimMc: AndreasO: More helpfully: It's best to wait until a lull in the conversation to ask your question, otherwise existing conversations will bury it.

16:29 amalloy: ridcully: yes

16:30 AndreasO: TimMc: sounds like politics!

16:30 ridcully: amalloy: thanks. that seemed to be the only thing to make it compile, but i hoped for something shorter

16:30 TimMc: heh

16:30 amalloy: TimMc: i dunno if i agree with that. i just ask questions whenever i feel like it

16:30 TimMc: ridcully: Yeah, needs to be an array, specifically.

16:30 amalloy: which admittedly is rarely these days

16:30 TimMc: It depends on the question, though.

16:31 justin_smith: ridcully: it shouldn't be hard to make a macro that handles it nicely

16:33 ridcully: i was just baffled by the error. i am not that keen on java itself, when it comes to things like this. this is just fooling around with pac4j via ratpack via catacumba.

16:33 AndreasO: A seesaw question. How do I address the root widget ? I'm using config! with select to change a canvas .

16:33 TimMc: ridcully: (whoops, just saw that you mentioned into-array)

16:33 amalloy: i don't think a macro would make this any nicer

16:34 ridcully: so once it works, i will isolate it in some ns and hope they will never introduce breaking changes in a x.x.n release again...

16:34 amalloy: (.foo a b (into-array MyObj [])) vs...what? (no-args MyObj foo a b)?

16:34 justin_smith: amalloy: I was thinking something like a marker keyword :& and automatically putting everything after that into an array

16:35 amalloy: ridcully: what are you talking about re breaking changes?

16:35 the varargs syntax was introduced in 1.5.0, breaking no existing code, and hasn't changed since then

16:35 ridcully: amalloy: this was a rant about pac4j - not java

16:36 amalloy: ah. they added an optional vararg param to an existing function, huh? that's an interesting change

16:37 spuz: if i want to create a fixed length array of booleans for use of random access (i.e. using nth) should I use a vector or a Java array/

16:37 ?

16:37 amalloy: it doesn't break any existing java source, and they could arrange for it not to break any compiled java code either

16:38 so i find it hard to blame them for introducing that; it's not *their* fault you're using some dumb language that breaks when they make a change that's forward-compatible in java

16:38 ridcully: amalloy: i am not even sure. the breaking change with classes was in 1.7.0 to 1.7.1; i had that simmering for a month or so now ratpack-pac4j adopted to that change and they introduced the varargs version. i have not looked into the details...

16:49 TimMc: spuz: Whatever your heart desires, but... vectors will probably be easier.

16:50 spuz: TimMc, well arrays seem easier to create, there is a boolean-array function. How would I create a vector of 100 false values?

16:50 AndreasO: Any seesaw gurus here?

16:53 TimMc: ,(vec (repeat 100 false))

16:53 clojurebot: [false false false false false ...]

16:53 TimMc: spuz: ^

16:53 amalloy: AndreasO: better to just ask your real question, on irc, even if you don't know who will answer it. nobody knows if they count as a "guru" enough to answer your question, or wants to agree to help with a problem of unknown size

16:53 TimMc: not that i disagree with your advice, our ancestors would be rolling in our graves if they knew how much space we use to store 100 bits

16:54 TimMc: AndreasO: The answer is probably "no, not right now". Maybe try tomorrow or at a different time of day, and not repeatedly in close succession.

16:54 amalloy: Yeah, I winced a little writing that. :-(

16:54 but I'm not going to tell spuz to use a bitset or something

16:55 AndreasO: TimMc: okay, need to sleep anyway. Got work tomorrow.

16:55 spuz: well BitSet makes the most sense for this application

16:55 it's just a prime sieve

16:55 TimMc: Oh hah, maybe you should use that then. :-)

16:55 spuz: but I guess I want to do it in the most 'clojure' way

16:55 TimMc: Be aware that it's mutable, tho.

16:55 amalloy: spuz: clojure favors practicality

16:56 spuz: amalloy, well practically I would use Java

16:56 that won't teach me new things though :)

17:01 sdegutis: Hi.

17:03 rcassidy: Hi!

17:05 audrius: sdegutis, Sigitas? :)

17:06 sdegutis: audrius: I am unsure of your meaning, friend.

17:06 rcassidy: hi!

17:07 audrius: sdegutis, I thought I found some person on IRC. newer mind it is not You then...

17:08 sdegutis: Sorry.

17:08 audrius: I mean, I /am/ me, for sure. I'm just not, who you thought I was? I guess?

17:08 audrius: well obviously :D

17:08 sdegutis: Hello! I am new to Clojure. How can format java Date using "YYYY-MM" please.

17:09 I may use Clojure 8 and Java 8. Thanks in advance regards.

17:09 This is NOT homework please note.

17:13 uris77: @sdegutis look at the clj-time library

17:15 sdegutis: Thanks uris77.

17:15 I will convert my Date to LocalDateTime using ZoneId, and then format it with DateTimeFormatter.

17:24 If you have a running app via `lein repl` and then do `lein clean` and `lein uberjar`, does that ruin the running app and/or result in a corrupted uberjar?

17:38 Looks like it corrupts the running copy only, and the generated uberjar works fine.

17:41 Mordus: Anyone know of a way to convert datascript Entities to maps? Datascript Entities are map-like, but they don't seem to be seqable. I'm using (d/touch (d/entity @db id)) to get entities out of the db, but want to use seqable functions on them.

17:41 justin_smith: Mordus: have you tried (into {} entity) ?

17:45 Mordus: Justin, thank you.

17:46 spuz: I would like to run something like (time (x)) without printing the value of x to the repl

17:47 is that possible?

17:47 amalloy: (do (time (x)) nil)

17:47 ie, construct an expression that does whatever side effects you want (here, timing (x)), and then returns nil

17:48 spuz: amalloy, ah yes do

17:50 Is there a cleaner way to find the index of an element in an array? https://www.refheap.com/947b1ecd160ffbe6e7111d97d

17:50 this code feels very procedural

17:52 patham9_: hi! are dependent types already usable in core.typed?

17:57 amalloy: spuz: why do you want indices to begin with? usually when you are dealing with indices in clojure you are missing a better solution

17:59 spuz: amalloy, I need to store a value of true or false for every number up to a limit

17:59 I also need to search that array for values that are true or false

18:00 amalloy: if you're implementing the classic prime sieve, you should never need to search the array

18:00 sdegutis: I agree with amalloy.

18:01 spuz: amalloy, really? how do you find the next prime to eliminate the multiples of?

18:01 amalloy: just keep counting up by 1

18:01 and skip elements that are false

18:01 sdegutis: amalloy: i like ur style

18:02 spuz: ok, that's what I'm doing

18:03 amalloy: the reason your array search feels very procedural is you're implementing a procedural algorithm procedurally

18:05 spuz: amalloy, so I can't avoid it?

18:07 amalloy: personally i would inline this function into the main sieve loop, but you can't avoid doing something with this general flavor

18:07 otoh if you were using a bitset instead of an array, it has relatively efficient methods like https://docs.oracle.com/javase/7/docs/api/java/util/BitSet.html#nextSetBit(int)

18:08 spuz: that's pretty handy

18:09 amalloy: internally, that's just a loop 1/64th the size of yours

18:27 TEttinger: I <3 bitsets

18:28 RoaringBitmap and JavaEWAH are good libs for compressed bitsets when you want lower memory usage and faster set operations on multiple bitsets. JavaEWAH has a Clojure binding too.

18:38 rhg135: are they immutable though?

18:38 amalloy: as immutable as an array of booleans

18:38 rhg135: ah

18:38 amalloy: well, a little less so, i guess, but it's comparable

18:38 and spuz is using an array of booleans already, so...

18:39 rhg135: mutability makes me sad, but eh

18:39 spuz: I better go but thanks as always for the help

22:51 patham9_: hi

22:51 What's the state of dependent typing in Clojure?

22:52 TEttinger: there are people here who could probably answer that, but I am not one of them

22:53 awwaiid: is that different than core.typed?

22:58 patham9_: core.typed has static typing / occurence typing, but I'm not aware of the state of the dependent types

23:00 TEttinger: patham9_: it's in the "upcoming" list for the main dev http://ambrosebs.com/

23:10 patham9_: there aren't a whole lot of languages with good support for dependent types, as far as I can tell. Perl 6 could be added to this list https://en.wikipedia.org/wiki/Dependent_type#Comparison_of_languages_with_dependent_types

23:17 patham9_: interesting

23:20 TEttinger: didn't know ATS had good support. it's consistently near the top of the cheesy benchmarks game, a.k.a. "how fast can we call a library with hand-optimized assembly to do it for us instead of solving the task idiomatically"

23:21 patham9_: can't wait to see this in core.typed :)

23:21 TEttinger: heh, it is a neat feature

23:22 patham9_: occurrence typing is already pretty near dependent typing
