geekosaur sounds like you mi have a struct (instead of a struct pointer) inside another struct, and it can't deal with that just as it can't pass or return structs by value? 02:21

masak uh, ok -- partial answer to my own question: if I do `skip("some_reason", 1); done-testing;` when aborting early from the test file, `prove` just marks the file as `..... ok` as usual. it doesn't propagate the reason 06:39

gregf_ er, Natural language processing, latent semantic indexeing :)
gensym/nltk - python/java 13:26
Frameless That really didn't help :)
Maybe you're confusing me with someone else?
gregf_ er, well , i thought you were zoffix *i may be wrong , but i may be right as well* 13:27
lol
Frameless gregf_: Zoffix doesn't know anything about that either :P
gregf_ oh - since i saw this: github.com/zoffixznet/perl6-RT-RES...Client.pm6
13:28 Possum joined 13:29 AlexDaniel joined
Frameless Yeah, I wrote that but I've no idea what you're asking, sorry :) 13:29
moritz I'm also confused about the relation between NLP and a bug tracker REST API
gregf_ heh 13:31
Frameless The grammar in that module just gets a REST response with a bunch of tickets and parses out their IDs, tags (stuff in [brackets]) and subject lines.
gregf_ long story made short - parsing text. theres the new one by google i think - spacey/parsey or somesuch 13:32
yes, my bad. the grammar was what i meant :! 13:33
moritz I don't know much about NLP, but I don't think Perl 6 grammars are a good way to tackle it
13:34 brrt left
gregf_ atleast i got something right haha.. Zoffix == frameless ;) 13:34
moritz: sure, just curious :) *nothing to lose*
sorry for the noise tho' 13:36
[Coke] (2 spaces after period) in the US at least, it was the proper way to type things out on a literal typewriter. 13:42
Frameless Ah
[Coke] some people still do it in source a lot, even though most renderings will collapse whitespace.
Psy-Q installing perl6-panda on debian and doing "panda" yields "Could not find Shell::Command at line 2 in:" (etc.). how can i find out what's wrong? should we even be using debian packages of perl6? (it's on testing)
moritz Psy-Q: sounds like the package is a bit broken. In that case I'd submit a bug report, and use a source build of rakudo 13:43
RabidGravy yeah, I do find it amusing with the web-age "typographers" railing against the two spaces thing, when they've probably never used a typewriter
it's amazingly difficult to get out of the habit.
Psy-Q moritz: alright, i'll try! 13:44
13:45 skids joined
Frameless I never realized using a typewriter was a prerequisite for being good a typography :) 13:47
From what I'm reading, the two-space thing was basically because typewriters used a monospace font.
gfldex Psy-Q: pl6anet.org/drop/rakudo-star-2016.07-RC1.tar.gz 13:48
moritz wouldn't it be a nice idea to try to make a mechanical typewriter with a variable-width font?
Psy-Q gfldex: oh, fankew, i just started reading the intro and grabbed rakudobrew, but maybe that's better then :)
Frameless FWIW, perl6-panda is just the panda, so I assume Psy-Q already has Rakudo installed
gfldex btw. I did install RC1 on a clean debian stable and it worked fine
[Coke] moritz: O_o;
Psy-Q yeah, i had perl6 from the debian rakudo package. but i'm happy to grab everything fresh, no problem 13:49
gfldex any .exe for star-2016.07 yet?
Frameless I like rakudobrew.
tadzik++
13:50 rindolf joined
Psy-Q ooooo, panda and rakudo just worked with rakudobrew 13:52
happiness ensued
[Coke] gfldex: nope. I have a windows laptop, I can give it a shot if there are directions (found some in star...) 13:53
Frameless :)
Psy-Q this is a lot less painfull than building rubies with rbenv \o/
*painful
[Coke] ... and it requires installing a ton of stuff I don't have. Will take a look this evening.
Frameless Psy-Q: FWIW, if you issues with panda in the future, you can give `zef` a try. It's an alternative package manager. rakudobrew build-zef will install it. 13:54
Psy-Q: yeah, it's pretty sweet. You can also install multiple perl6 versions with it too
Psy-Q Frameless: i'll make a note of zef then
but baby steps. my last perl was in 1997 or so
Frameless :o
Psy-Q: then it's worth nothing that we have two sister Perls now: Perl 5 and Perl 6. Both are actively developed :) 13:55
Psy-Q i've seen larry talk at FOSDEM two years ago :D
but i had 2 years latency to actually get into it now :) 13:56
Frameless: much interested in perl 6 (less so 5) since it seems to combine a few of my favorite things, and it seems to be more enjoyable to use than many

DrForr Join the crowd. 14:01

mst Psy-Q: if you do have reason to use perl5, remember Moo/Moose provide a similarish set of OO, within the limitations of the older language 14:01
Psy-Q mst: i think i heard that Catalyst uses Moose and i might be interested in that. but i'll fool around with perl6 web stuff too :D 14:03
mst Psy-Q: oh, absolutely, this is an 'and', not an 'or' :D
Psy-Q wheee!
mst but basically the inheritance goes 'old perl6 metamodel' -> Moose -> 'current perl6 metamodel'
which much theft of ideas back and forth, because that's how open source is supposed to work 14:04
gfldex Psy-Q: reading about the traps early may be helpful docs.perl6.org/language/traps
Psy-Q i might end up very blasphemous and not go much OO at all
mst that's fine, both languages are totally designed for you to do that too
Psy-Q i was learning some clojure so i might be interested in doing something FP'ish on perl 6
mst my perl5 code tends to be very functional
see shadow.cat/blog/matt-s-trout/do-you-copy/
the pattern is totally applicable to perl6 as well

kyclark I'm working on a longest common substring problem. As I move from shorter to longer, I would like to use the previously found shorter strings to filter the longer matches, so I'm thinking about having an Array of Regexes. Can/should I do this? 18:49
18:50 spider-mario joined
moritz an array of regexes sounds suspiciously like you'll be re-doing all the matches 18:51
18:51 sufrostico left
moritz from a performance perspective you might want a more dynamic programming-like approach where you only need to check the new characters to go to longer strings, or something like that 18:52
but tbh, I'm not so deep in the topic to know for sure
kyclark Is it possible to do something like 'foo' ~~ /@re/? 18:54
Also, I can't figure out how to even create an array 18:55
moritz my @array;
kyclark m: <foo bar baz>.map: -> $s { rx/$s/ }

perigrin sure but then that's *your* array ... how do you create one for kyclark

dogbert17 gfldex: thanks for the explanation 20:24
20:24 Actualeyes joined
kyclark This is my first attempt to use Promises. My search for a longest substring can work independently over the various string lengths, so I thought I might try to parallelize this. It's only going up to 20 instead of the full length because it's running wicked slow and I wanted to see if it would indeed process things not in order. It does, but am I doing something wrong to make it so slow? 20:24
gfldex dogbert17: when you describe a feature of a thing in Perl 6 that is represented by a class (so pretty much anything) you don't want to side track to much in the text. The example however can show such a side track without forcing the reader to pay attention. 20:25
kyclark: you create tons of one shot data structures that force deep copies of other one shot data structures (AFAICS) 20:28
perlpilot kyclark: You could try to use the profiler to see where the bottlenecks are 20:29

gfldex kyclark: if you want to quickly test if your program runs fine without promises add: sub _await(@l){ do for @l -> &e { e() } }; sub _start(&c) { &c }$ 21:18
and then change start to _start and await to a 21:19
to _await
hoelzro a little OT, but this is pretty cool: divan.github.io/posts/go_concurrency_visualize/ 21:20

kyclark gfldex: I had it working in a straight-up for loop, and then I threw in the promises. When things went much slower, I figured I didn't know what I was doing. 21:22
hoelzro ah, requires a patched Go runtime
I beat we could do it as a library =)
Zoffix Yeah, very neat.

Actually, it doesn't make sense in the context of promises.
If one is going from 2..$max, then just stop when you don't find a match.
Max for this problem set is 1000, which is high, but it almost makes more sense to start at max and stop when you hit the first common substring. 21:28

gfldex kyclark: ^^^
how do I do last in a start block?
m: put do await start sub { return };
camelia rakudo-moar 6ef9e0: OUTPUT«Sub object coerced to string (please use .gist or .perl to do that) in block <unit> at <tmp> line 1␤␤»
gfldex m: do await start sub { return }; 21:34
camelia ( no output )
timotimo yes, in order to return out of something, it has to be a sub 21:35
gfldex that doesn't work either, what is no wonder
timotimo because "return" goes through regular blocks
if you want to use the start "syntax", you'll have to use bare blocks, iirc
jnthn do await start sub { return }() # just invoke the sub with some dog balls ont he end
*on the 21:36
timotimo ah, or that
that's a good trick, but it's ugly that we have to do it
kyclark Like "truck nuts"?
21:36 addison left
jnthn Well, better is just to factor out the stuff you want to do into a subroutine and start the-sub() or so :) 21:37
timotimo that's probably better

kyclark Is there anyway to have ADT (algebraic datatypes) e.g., Direction = Up | Down (the way that Bool = True | False)? 21:55
AlexDaniel kyclark: use enum?
Bool is an Enum too 21:56
timotimo kyclark: try the ADT module
AlexDaniel oh, did I misread it completely 21:58
AlexDaniel hides
lizmat m: enum Direction (<Up Down>); dd Up, Down, +Up, +Down # kyclark: so that's not what you mean ? 21:59
camelia rakudo-moar 8cfd34: OUTPUT«Direction::Up␤Direction::Down␤0␤1␤»
timotimo ADT also has the possibility to hang data off of the bits 22:00
you may know Maybe a = Just a | Nothing, it's a rather famous one 22:01
kyclark Enum seems to work well enough. I can say "binary_search (Int $n, Direction $dir)"
gfldex kyclark: the speedup from threading is actually quite nice, given the problem
