George hi 02:09
what is this? 02:10
teatime It's a dream, George. 02:11
(This is the user support / discussion channel for the Perl 6 programming language)
02:12 BenGoldberg joined 02:14 kitsunenokenja joined 02:20 adu left
comborico1611 Heh 02:21
I once showed my school buddy back in 1999 IRC connecting, and he thought i was "hacking". 02:22
I had the background black, and all the flashing text and colors looked hacker legitimate. 02:23
George I mean what kind of information can one ask for here?
comborico1611 Information about the programming language Perl 6. 02:24
George It says how to get started, but 'm just reading the tutorial, I was just curius about it 02:25
I've never seen this sort of thing before 02:26
teatime You're welcome to ask questions etc. that come up as you go through it.
Like Perl6? Or an IRC help channel?
comborico1611 I was curious about programming back in 2000, then 17 years and by, and just this summer i got back into it.
I'm pretty sure he means irc. 02:27
02:27 adu joined
George both acually 02:27
comborico1611 I think his head is reeling a bit by the ircness of irc.
Heh 02:28
George I come from Haskell
comborico1611 Weird. Know any others?
George they say perl 6 is functional so I was giving i a try
like programming languages?
yes 02:29
teatime it can be, I really like how successfully it is 'multi-paradigm'
George I mean I started learning haskell recently
comborico1611 Oh okay. Not weird anymore.
teatime I have tried to learn Haskell about 3 times.
I think I must have been smarter when I was younger.
George I am liking it actually
comborico1611 I got the impression you were a young'n that hadn't been introduced to the programming culture. 02:30
rashipi At one point, a Perl6 compiler was the most important Haskell aplication and drove Haskell development.
teatime yiss
although it was before my time with it
comborico1611 Hmm. Didn't know that.
rashipi As languages, they were developed togheter.
teatime but the links between haskell and perl6 become apparent from time to time 02:31
comborico1611 Hmm.
George yes I heard that
02:31 llfourn_ joined
George but if one has never coded in perl before is perl6 a good starting point? 02:31
geekosaur I'd argue it's a better starting point than perl 5, unless you need to use perl 5 later. 02:32
perl6 is much less idiosyncratic --- it behaves consistently, whereas perl 5 is kinda infamously a mass of special cases
teatime perl6 is fun. that's about all I can contribute. 02:33
(perl5 was a lot of fun too, but I don't think it would be again if I were starting today.) 02:34
George yes I'm starting to get an idea from the pearl from Haskell tutorial and the one from Python
02:35 llfourn left
rashipi Pearl is another language. 02:36
teatime George: the name misleads a lot of people into thinking they're super-closely-related; they're not so much, they're different languages.
perl 6 and 5 I mean
George ok ok
geekosaur they're conceptually related, nbut that's as far as it goes 02:37
02:38 ido joined, ido left
geekosaur there's a number of core ideas that are in common, intentionally, which is why we call it perl. but perl 6 is taking advantage of a lot of general development in programming languages to express those core ideas in a more consistent and better organized way 02:38
comborico1611 George, what languages do you know? 02:41
George C/C++ Python and \JS
and a little of PHP 02:42
comborico1611 I've never heard of the backslash one.
teatime "escape JavaScript" is a popular developer goal :)
George thats a typo
comborico1611 Lol 02:43
George ahahah

Herby_ with regex and grammers, what is the difference between | and || 03:14
if any
teatime there is a difference, 1 second
I beleive one matches in order given and the other matches longest alternative 03:15
but let me find the actual docs
docs.perl6.org/language/regexes#Alternation:_||
rashipi | is for longest match 03:16
|| is left to right.
Herby_ thanks!
rashipi 'dog || doge' will never match doge 03:18
Herby_ teatime: thanks for the link
03:20 adu left
Herby_ rashipi: and 'dog | doge' will always match doge? 03:22
assuming doge is actually in the string
teatime yiss
rashipi m: say 'doge is the word' ~~ /dog|doge/ 03:23
camelia ｢doge｣
rashipi m: say 'doge is the word' ~~ /dog||doge/ 03:24

rashipi what you're trying to do? 04:48
Herby_ as an exercise, I'm trying to write a grammar to parse torrent names
pastebin.com/jwbjyQCv 04:52
the title matches everything except the end: -ASAP[ettv] 04:53
season, episode, and resolution dont match
rashipi because it's greedy 04:54
Put a ? to turn it frugal 04:55
that way it will match the least possible
Herby_ where do I put the ?
teatime heh I've never heard that called frugal... I like it 04:56
rashipi It's in the docs, haha
Then it will match a single letter
04:58 khw left
Herby_ no luck. 05:02

ZzZombo Say, I have a grammar rule A that calls rule B, can I in my actions object get the match for A for the corresponding match B inside the action method? 05:14
05:21 thowe joined 05:23 pentashift joined 05:26 llfourn_ left
geekosaur uh? B doesn't know if it can only ever be called by A, and if tyhat *is* the case then there's likely some refactoring that will give you both 05:32
now if you mean from A's action method, B should be available as a named submatch 05:33

wander Here is an interesting example, I think, of the topic "container" 08:59
"container" is considered as one of the most hard topic to understand of Perl 6 by people around me. 09:02
09:02 domidumont left
wander So I want to attempt to figure out how we design Perl 6 "container", the only article I found about it is from the doc site. 09:03
wonder if there someone ever talked about it, such like in a blog or something.
one of the most annoying cases is an Array `[ ... ]' sometimes becomes `$[ ...]` 09:05
09:13 poohman left 09:20 Cabanossi left 09:22 Cabanossi joined 09:33 espadrine joined, mryan50 joined, zakharyas joined
mryan50 wander: [ … ] is an array container; $[ … ] is a scalar container holding a reference to an array container 09:35
… well, at leat I think that’s how it is 09:36
s/leat/least/ 09:37
wander yes, i know this. you can see the example above about '%h' and '@a', so @a happens to be convert form array to a refer, interesting and confusing when you first meet it. 09:39
09:45 lizmat joined
wander scalar containers, callable containers and etc.. when they appear singly, things go well. but variable is passed and thus container changes, here things go, somehow, confusing 09:47
so i wonder if someone has had a talk about this topic :P 09:50

wander no. i don't remember it, some i have met but fixed in someway so i forget it. i will ask for help if facing a very issue. however, my friends who i recommend Perl 6 to tell me the concept "container" is not so clearly 10:12
so i don't ask for help to fix a particular issue, but look for a talk about "container" 10:13

Herby_ anyone know how to get hexchat to properly display camelia's unicode characters? 17:10
teatime Herby_: Can you see → my arrows ↔ 17:12
Herby_ yep
teatime then I think your problem is just that your configured font lacks the glyphs being used
maybe try DejaVu instead 17:13
or Unifont, if you want an ugly font that has almost literally everything
(if you can specify a "fontstack" to search for glyphs, ending it with Unifont works great.)

teatime well kindof
oh, yes, nevermind
poohman kindof??
teatime didn't realize the grep wasn't anchored 17:18

poohman could I use something like this in Grammar - stringify it in some way 17:59
??
teatime you can use it in a grammar without stringifying
poohman really - will it work directly?? 18:00
teatime yup
that's what it's for :)
poohman wow 18:01
let me try it
back to programming after some years - so I dont really know how it is with other languages - but is something like this possible in the new generation languages 18:03
i mean is this possible in most of the new generation languages
or is it perl6 magic here??
teatime grammars like Perl6 has are pretty unique to perl6 18:04
when feeling optimistic, I expect them to spread and be loved the same way perl5 advanced regular expressions 18:05
poohman 😆 - I tried the following just as a test - didnt want to be surprised again 18:06
m: my $months=['Jan', 'Feb' ...'Dec']
camelia ( no output )
teatime there are grammar/parser implementations for other languages (e.g. Marpa), and there is the older tech of parser generators etc., but perl6 builds it into the language, and makes it very quick and easy to get started with
heh, I don't expect that'll work 18:07
poohman It did give a result though
teatime m: say ['Jan', 'Feb' ... 'Dec'].first(12)
camelia Nil

no I meant integration of lazy lists etc in Grammars

lucs Where are string escape sequences documented? (like \n, \o, \c, etc.) 19:46
19:47 kybr joined
teatime lucs: there's more of it here than initially meets the eye, if you read the paragraphs: docs.perl6.org/language/quoting#Escaping:_q 19:50
if I'm not overlooking an exhaustive list elsewhere, though, it could def. be improved. 19:51
lucs Yeah, maybe it would be nice to have a list somewhere, cross-referencing to the proper documentation. 19:52
I'm actually wondering if there's an escape to enter a decimal value, like one enters an octal value (so \077 would be something like \d119). 19:54
teatime looks like \c[] should do it 19:56

(List, :$html is copy)
I'm pretty sure the last candidate could match
Juerd It does look rather matching :) 22:37
gfldex the first two candidates are in module A and the last one in module B 22:38
could that confuse Rakudo?
timotimo it shouldn't 22:39
you could try to output the candidates at the exact point it breaks
to make sure the list isn't different because of error reporting issues? 22:40
gfldex there is some nqp trickery in module A involved
in this line github.com/rakudo/rakudo/blob/mast...y.pm6#L714 22:41
(to me that nqp spell could very well open a gate to hell :) 22:42
no sorry, wrong line, right line: github.com/rakudo/rakudo/blob/mast...y.pm6#L721
timotimo ah, no 22:44
that's just a shorthand for "assign a value to this attribute and return the object that was assigned into" 22:45
i.e. do { bindattr($obj, Type, '$!attr', $value); $obj }

camelia Nil
Herby_ where am I going wrong? (sorry to pepper with questions)
jnthn Expecting regexes to be stringier than they are. In fact, they're more like subs, and the match state is per sub 23:44
m: my $p = '(\d)\d'; if '23' ~~ / <p=$p> / { say $<p>[0]; } 23:45
camelia ｢2｣
Herby_ my ultimate goal is I have an array of pattens, and I want to loop through the array and apply the patterns to a string and extract the captures
jnthn Can explicitly capture it like that
m: my $p = '(\d)\d'; if '23' ~~ / <p=$p> / -> :p($/) { say $0; } # hmm :) 23:46
camelia Cannot resolve caller postcircumfix:<[ ]>(Mu, Int); none of these signatures match:

jnthn That lets you refer to the inner things as $0 etc.
23:47 wander left
Herby_ jnthn: thanks. i'll have to try and parse that mentally :) 23:48
perlawhirl Herby_: alternatively... eval your string into an Regex... unless it makes you feel dirty
ie: my $s = '(\d)\d'; my $p = EVAL("/$s/"); if '23' ~~ $p { say $0; } # Can camelia EVAL?
m: use MONKEY-SEE-NO-EVAL; my $s = '(\d)\d'; my $p = EVAL("/$s/"); if '23' ~~ $p { say $0; } 23:49
camelia ｢2｣
jnthn If you're going to apply them many times, that would probably be more performant, yes 23:50
Well, if doing all the EVALs up front I mean
Herby_ perlawhirl: thanks. I don't feel dirty cause I still am trying to figure out what I'm doing :)
perlawhirl yeah... @patterns = @strings.map: -> $s { EVAL("/$s/") } # now you have a list of Regex's 23:51
Herby_ perlawhirl and jnthn: thanks for the ideas 23:53
perlawhirl lizmat: I tried out toggle. I like it so far... provides something akin to takewhile/dropwhile, but more general. 23:57
