geekosaur Str 04:37
that is, it's a type object
(Any should also work)
Herby__ geekosaur: thanks
i'm looking at some python code that looks like: self._part(name, [], None, clean)
geekosaur m: my Str $a = 'foo'; $a = Str; dd $a 04:38
camelia Str $a = Str
Herby__ so in p6, it might look like: self!part($name, (), Any, $clean) ?
geekosaur generally we prefer the most specific typed undefined applicable
so it depends
(since types help the compiler catch mistakes) 04:39
Herby__ gotcha
geekosaur m: my Str $a = 'foo'; $a = Any; dd $a
camelia Type check failed in assignment to $a; expected Str but got Any (Any)
in block <unit> at <tmp> line 1
geekosaur right, didn;t think it would do that
although in that context (only) Nil also works... but it's not general; for a variable, it means "set to whatever was specified by 'is default' trait, or the type's default if none" 04:40
Herby__ geekosaur: thank you. one more basic question. passing an empty anonymous list as an argument? 04:42
self._part(name, [], None, clean)
geekosaur that .. depends. I'm still a bit confused by promotion and when Array works for List 04:43

Herby__ Do you futz with functional programming much? 04:48
geekosaur uh. I'm one of the maintainers of xmonad
Herby__ I'm a rookie and I have a hard time with writing OO
geekosaur (tiling window manager written in Haskell) 04:49
Herby__ ahh
you familiar at all with python?
geekosaur not very
I can read it, haven't written very much
Herby__ I'd like to convert this (relatively) simple python library to Perl 6. But i stumble with OO
github.com/divijbindlish/parse-tor...N/parse.py
lookatme just like me :)
Herby__ vague question, but could I tackle that with FP? 04:50
FP in perl6
04:50 astronavt left
geekosaur honestly? if I'm parsing in perl 6 I'd write a Grammar, rather than doing it manually 04:54
tony-o FP ? 04:55
lookatme Hmm, seems like it is a parser
Functional Programming
tony-o ah 04:56
you could write that parser in a grammar or with fp (i wouldn't write oo for _that_ one in particular) 04:57
lookatme github.com/araraloren/perl6-getopt...arser.t#L6 A simple grammar 04:58
Herby__ I did try my hand at a basic grammar for it: pastebin.com/zmiEnNBE 05:00
ignore the line numbering
lookatme So grammar is OO style ?
Oh, you parse a torrent file ? 05:01
05:01 Cabanossi left
geekosaur it's sort of modified OO, but your 'methods' are perl 6's extended regex syntax 05:01
token, rule, etc.
tony-o grammar is, kind of, a more sophisticated regex
Herby__ grammars seem to have a steep learning curve to do anything useful. for rookies at least 05:02
geekosaur kinda got sucked into a support issue elsewhere, sorry
tony-o and you don't _need_ the actions bit in that file

wander is this normal? ':dba' is used for error messages, but it looks like even break a trivial matching 12:08

jnthn I'm not totally sure we ever implemented :dba in Rakudo 12:09
It's certainly in NQP, 'cus we use it for a load of error reporting :) 12:10

matthias__ Hi everyone. How can I type a constant? As in give it a type.
Zoffix matthias__: it's a constant. It doesn't need a type 16:02
DrForr Didn't say it was, pmurias was asking rhetorically "why..."
Zoffix DrForr: you mentioned flame fanning. That sounded like critique against writing to me :) 16:03
DrForr Coming from someone who's just written a blog post and is writing an advent post over the weekend :) 16:04
It would be hypocritical of me to advocate against writing and then go on writing :)

Zoffix There're 24 posts altogether; one per day, so number of spots is limited
comborico1611: why not?

comborico1611 True.
perlpilot comborico1611: what DrForr said. Share your experience
comborico1611 Haha. You guys are funny.
DrForr Which book, BTW?
comborico1611 Think Perl6
perlpilot comborico1611: alternatively, you could give a kind of book review :) 16:09
matthias__ jnthn: So whenever I explicitly add a type I have to explicitly set `my` or `our`? Is there reason for constants not defaulting to `our` in that case as well?
DrForr Ah cool, I need to pick up my copy; probably at FOSDEM and see about getting it signed :)
comborico1611 Hmm. I do have a book review in-the-works for this book.
Nice.
16:10 Ven`` left
comborico1611 I want to hear jnth say a book review would be fine for Advent post. 16:10
Zoffix comborico1611: see my last eval above; jnthn's way isn't working. It's constant without a container and with a mandatory. It doesn't need a type. How come you're trying to set the type?
comborico1611 Then i will do it. :-)
Zoffix A book review is fine for Advent post. 16:11
*mandatory value
jnthn matthias__: The declarator is required so we know to parse a type next. That's just the way the syntax works; it's consistent with every other declarator in the language.
comborico1611 Alright.
perlpilot comborico1611: it's weird that you would single one jnthn as the arbiter of what's good for an advent post.
comborico1611 I'm not trying to set a type const. I was just trying to answer matthias's question.
DrForr No need to ask permission, just add yourself to the list :) 16:12
Zoffix comborico1611: oh, right, too many people. Wrong person :)
perlpilot s/single one/single out/ # I swear, my brain is weird
comborico1611 Perlpilot, yeah, sorry no offense. I just don't know who's in charge here. And I don't want to commit myself to that post and look like an idiot if that content isn't suitable for Advent.
Zoffix No one's in charge. Anarchy \o/
comborico1611 I doubt that. 16:13
I will sign.
scimon So.... I love perl6's operator chaining. Is there a good explanation anywhere of how it works though?
m: say [(^)] ( (1,2,3,4), (5, 8, 9), (2,3,4,5), (5,8,9) ).pick(4)
camelia set(1)
perlpilot comborico1611: okay ... I'll claim to be "in charge" since colomon and I first setup the Perl 6 advent calendar all those years ago. And since I'm in charge. Write something! We'll help if you need it. 16:14

Zoffix scimon: that one just introspects the op you're using to figure out which one of META_BLAH_BLAH routines to call under the hood. For the `(^)` op, it calls these: github.com/rakudo/rakudo/blob/mast...#L401-L415
comborico1611 But my goal in this review is to express when I truly feel the best way to learn to program is. Because his book is set up as an introductory course to programming.
scimon Right I'll now not think about it until Monday (Party tonight... recovery this weekend)
comborico1611 When equals what*
scimon Zoffix: but it's more how it manages to handle things like 1 < 5 < 10 16:23
The number of languages that can parse and manage to give a sane answer for that are minimal.
I mean in the example I gave 16:24
Zoffix m: sub infix:<z> is assoc<chain> { dd @_ }; 1 z 5 z 10
camelia [5, 10]
[1, Nil]
scimon m: (1,2,3,4) (^) (5, 8, 9) (^) (2,3,4,5) (^) (5,8,9)
camelia WARNINGS for <tmp>:
Useless use of "(^)" in expression "(1,2,3,4) (^) (5, 8, 9) (^) (2,3,4,5) (^) (5,8,9)" in sink context (line 1)
16:24 ryn1x_ joined
scimon m: say (1,2,3,4) (^) (5, 8, 9) (^) (2,3,4,5) (^) (5,8,9) 16:24
camelia set(1)
scimon In most languages that could do the set stuff you'd end up doing (1) (^) (5,8,9) and get (1,5,8,9) 16:25
Zoffix Though for `<` op, there's additional chainage with other ops. That's currently not available in userland for custom ops and is done by the compiler.
scimon Like I say... it's stunning and something we should be talking about more.
(I'll be mentioning it in my Advent page)
Hats of to all involved. Time for me to find some drinks. 16:26

ryn1x_ I would like to do some IPC from perl6 to a c++ program. I have never done IPC in any language before and am not sure where to start. What would be the Easiest solution (not worried about performance right now)? I want to start by sending a message containing a file path from my perl6 program to a c++ program. I have read that some possible methods are sockets, named pipes, SQLite, and shared memory. I need to pick one and start lear

clarkema Hi all. I'm playing around with the Advent of Code as a source of little puzzles for learning Perl 6 (adventofcode.com/2017/day/1) I have a working solution for today's two challenges, but I'd love some feedback on style and idiom. My solution is at gist.github.com/clarkema/d0b6d8d95...474861db2a -- in particular, it feels like there should be a better way to get an array of digits out of the string. 20:54
Any pointers very gratefully received!
masak m: .say for "65536".comb
camelia 6

6
clarkema ah, thanks! 20:55
masak :)
in general, `.comb` is the opposite/dual of `.split`
`.comb` is for when you want to keep things. its default is per-character 20:56
clarkema that's really handy, thanks! It looks a lot less ugly 20:57
20:58 astronavt joined
clarkema so you're specifying what you want, rather than what you don't, and you don't get the extra two empty matches at each end 21:01
AlexDaniel m: my @d = โ€˜911229โ€™.comb; @d .= push: @d.head; say sum gather for @d.rotor(2 => -1) { take .head if [==] $_ }
camelia 12
AlexDaniel rotor, gather/take, [โ€ฆ] :) All in one snippet 21:02
21:03 astronavt left 21:04 geospeck left
clarkema *reading up on rotor* 21:04
AlexDaniel m: say โ€˜12345โ€™.comb.rotor(2 => -1) 21:05
camelia ((1 2) (2 3) (3 4) (4 5))
clarkema That's pretty cool - I originally started off wondering if I could extract pairs like that but couldn't find an easy way to do it; so it's nice to see a solution for that approach
21:06 leah2 joined
clarkema (although as a spoiler the next part of the challenge involves testing against the digit half way around the array, instead of the neighbough, so I ended up rotating on (@digits.chars/2) 21:06
What's going on with the 'push:'? it obviously expands to something like @d = @d.push(@d.head), but I havn't seen an explanation of the colon approach 21:11
teatime `push: a;` is equiv to `push(a)` 21:12
docs.perl6.org/language/syntax#Precedence_Drop 21:13
clarkema Interesting, thanks -- didn't really know what to search for that one. Definitely looks like something to beware of on longer chained calls 21:15
AlexDaniel Is that the reduction metaoperator in the take clause (as in, you're reducing a two-element list from the block argument to a boolean) or is something else happening? 21:22

perlpilot clarkema++ thanks for reminding me about adventofcode.com :) 21:30
21:32 Cabanossi joined 21:36 kerframil left
AlexDaniel clarkema: yeah, it puts == between the elements of the list 21:36
clarkema: so it's pretty much identical to .[0] == .[1]
(given that you only have two values)
clarkema Great -- I had the feeling my grep option was a little verbose
perlpilot: It's really handy to have some little challenges like that to provoke questions when learning something new! 21:37
21:39 integral_ joined, integral_ left, integral_ joined
perlpilot clarkema: yeah. It's also great just to play :-) I found out about it last year in the middle of advent and started writing some Perl 6 solutions, but I got side-tracked and didn't do them all. I'm going to try to do them all this year. We'll see how it goes 21:39
21:40 integral left 21:41 integral_ is now known as integral

afresh1 but I'm terrible at perl6, so looking forward to seeing what other folks here say 21:43
perlpilot Looks like all of the Perlย 6 Advent slots are filled (yay #perl6 people!) but I bet some of the adventofcode.com solutions would be worthy of a future Perlย 6 Advent post
the adventofcode problems kinda remind me a little bit of MJD's Quiz of the Week 21:45
clarkema afresh1: some interesting stuff in your solution as well; TI certainly MTOWTDI

afresh1 going to go try to actually understand `comb` and `rotor` now though :-) 21:46
clarkema it's nice to see your :skip-empty as well though

perlpilot baest: yeah, someone mentioned that yesterday I think and I was guessing leapseconds, but there's only been 26 of those. 21:50
in any case, it seems very familiar to me though I don't know the reason why 21:51
teatime GMT time is off 18 seconds from UTC
but that doesn't help
baest perlpilot: :)
teatime TAI is off from UTC by at least 34.1 seconds 21:52
perhaps more, dunno how old my reference is
perlpilot confluence.qps.nl/display/KBE/UTC+...Correction 21:54
See the first paragraph
teatime en.wikipedia.org/wiki/International_Atomic_Time
it's TAI, 37 seconds from UTC
mmm
21:55 konsolebox_ left
perlpilot so it is leap seconds plus the initial difference of 10 seconds 21:55
21:57 konsolebox joined
baest Wow ok, that explains it I guess, but still not very useful that you can't create a DateTime with an Instant from another DateTime and expect them to be the same time 21:58
perlpilot Why are you converting your DateTime to Instant anyway? 21:59
21:59 astronavt joined
teatime Instant is by def. TAI 22:01
whereas DateTime's are in UTC or zones offset from UTC
but, they should round-trip...
masak .oO( this isomorphism is bent! ) 22:02
22:04 astronavt left
baest perlpilot: storing them in a database as an int 22:07
perlpilot baest: why not store them as a string in ISO8601 format? 22:08
teatime it may not be different, at least for you / at the moment, but perhaps .posix would be more appropriate
or, yeah, even better that
22:09 nebuchad` joined
baest more storage with a string and I like being able to manipulate easier through SQL. Should probably use PostgreSQL and store them as a timestamp 22:10
perlpilot pg groks ISO8601 too 22:11
and I'll point out that concern over storage space is what caused all the Y2K hoopla 22:12
22:14 cdg joined 22:15 Cabanossi left
baest still with SQLite as I use currently you will not be able to manipulate them easily. But the important thing for me is to know what caused the thing 22:15

kupopo I'm getting a cryptic error when trying to `make install` rakudo-star-2017.10: ./perl6-j tools/build/install-core-dist.pl $PREFIX/share/perl6 fails with Unhandled exception: VMArray representation does not implement bind_pos_native. Has anyone seen or heard of this? (Google didn't turn up anything useful) 23:46
lizmat kupopo: could you add --ll-exception after ./perl6-j and gist the output ? 23:48
kupopo: otoh, I'm not sure of the state of the JVM backend even allowing a "make install" at this time 23:49
kupopo lizmat: here's the full stack with --ll-exception: gist.github.com/shicks/27df7cf0d86...50942d4c62 23:52
I'm a bit confused about that - my understanding is that the JVM backend is basically usable, no? Is it not meant to be installed? 23:53
lizmat bartolin would really be the person to answer this question, as he's been the one working on the JVM backend lately 23:55
personally, I have focused all of my efforts on making things faster on the MoarVM backend
.ask bartolin is gist.github.com/shicks/27df7cf0d86...50942d4c62 something you'd expect from a "make install" ? 23:56
yoleaux lizmat: I'll pass your message to bartolin.
lizmat kupopo: but from the error message, it would seem to me there's something not implemented on the JVM backend that is being used in the install process
and/or not properly worked around on the JVM backend 23:57
23:57 ctilmes joined
lizmat :-( 23:57
lizmat hopes bartolin can share some insights
kupopo Thanks. I guess I'll ask my more general "what are you actually trying to do?" question - I'd like to share a perl6 program with folks who don't have perl6 installed. I'd hoped to try using a jar file for this (and maybe that wouldn't work anyway), but maybe there's a better supported solution? 23:58
(i.e. perl6 is not standard in any linux distributions I'm aware of, unlike perl5 which one can generally assume exists) 23:59
