Zoffix MasterDuke, what have you done? :) 01:12
AlexDaniel “Shit” – hahaha :D
Zoffix :)
MasterDuke ha. that's what happens when i accidentally make a PR from my master, not a branch, and then pull --rebase && push so origin isn't behind rakudo/nom 01:13
AlexDaniel wait, did you rebase it other way around?
01:14 bob777 joined
MasterDuke my local checkout didn't have my PR commit. so i pulled from origin (my rakudo fork on github which did have that commit) --rebase 01:15
AlexDaniel yeah. You have all other commits on top of your “Fix RT #118223” commit
synopsebot6 Link: rt.perl.org/rt3//Public/Bug/Displa...?id=118223
01:15 mcmillhj joined
MasterDuke and then pushed, since my origin was behind 01:16
my local was at rakudo/nom HEAD, my github was at approx rakudo/nom HEAD~100 01:18
of course if you merge that PR i can't make that mistake again... 01:19

MasterDuke or can you, do i need to revert and push --force so it doesn't try to merge those already existing commits again? 01:20

AlexDaniel MasterDuke: yes, you can --force to update your PR 01:21

sammers lizmat, thanks. I was looking to use it for auditing the channel draining as part of a test 06:09
the jvm commit message says "Make Channel.peek private, as it is not specced", but couldn't find any further references to it 06:10
lizmat sammers: have you tried ?$channel[0] 06:12
sammers lizmat: I will take a look 06:13
06:15 Xliff joined
Pierre_ another "sketchy solution 06:19
you could do somethign like that:
m: role Countable { has $!how-many = 0; method send( | ) { $!how-many++; callsame;}; method receive( | ) { $!how-many--; callsame;}; method count() {$!how-many } }; my $c = Channel.new but Countable; $c.send(1); $c.send(2); say $c.count(); $c.receive(); say $c.count(); 06:20
camelia rakudo-moar beec02: OUTPUT«2␤1␤»
Pierre_ how ever, it will have bugs with concurrency 06:21
but if you play with the Metamodel, you could probably make it safe
sammers lizmat, I don't think ?$channel[0] will work... 06:22
m: my $ch = Channel.new; $ch.send("tester"); say ?$ch[0]; say $ch.poll; say ?$ch[0];

camelia rakudo-moar beec02: OUTPUT«True␤tester␤Channel.new␤»
sammers also, acording to the docs we should be able to use .elems on a channel, but it hangs when I try using it.
Pierre_ elems is working 06:23
once the channel is closed
lizmat ah, it's using the Mu.AT-POS and Mu.elems
Pierre_ m: my $ch = Channel.new; $ch.send("tester"); $ch.send("tester"); $ch.close(); say $ch.elems
camelia rakudo-moar beec02: OUTPUT«2␤»
lizmat so yeah, that won't work
sammers ah
hmm
Pierre_ but it empties the channel
sammers yeah 06:24
Pierre_ anyway, once close, i don't think you can receive anymore
sammers I like that .peek idea, just want to see a current queue length
06:24 canopus left

i mean receive on a closed channel 06:25

sammers hmm
Pierre_ ok, on an empty and closed channel, you can't
sammers ok
well, good to know.
lizmat perhaps .elems should be non-destructive on a Channel 06:26
sammers it would be nice
lizmat is testing a patch
Pierre_ howver, it is only available when the channel is closed
like list
lizmat hmmm... patch segfaults 06:27
Pierre_ it's using the iterator under the hood i think
06:28 canopus joined, mcmillhj joined, darutoko joined 06:33 mcmillhj left
lizmat Looks like Moar doesn't like you doing nqp::elems on a repr('ConcBlockingQueue') 06:35
I think .elems on a Channel should be non-destructive 06:36

Pierre_ with self.c you could create the method in runtime 08:29
so it can't tell for sure that it will not be there at runtime
Woodi Pierre_: ok, then I have problem with metods... 08:30

Woodi Pierre_: I was talking just about not detecting things at "compile" time, whateverTime. problems like that ar detected too late, at runtime. for me it's worse then not making, at least, warning about undeclared variable 08:54
moritz note that you should .^compose the class again after .^add_method 08:55
if you don't, you might get inconsistent behavior through the method cache

Pierre_ you would kill the functionality of being able to dynamically add method ;) 08:59
if you use a variaable, and not a method call, it is detected at compile time
jnthn The point of objects is late binding. 09:00
09:00 wamba left
Woodi Pierre_: I know it's about functional niceness, etc. but didn't have idea it's so 0/1... 09:01
but there was some notation of telling that class is finished, right ? 09:02
jnthn If you want early binding, use subs. :-)
Woodi jnthn: in classes and OO ?
jnthn If you don't want late binding, why do classes and OO? :) 09:03
rightfold use hashes of subs
Woodi jnthn: you obviously trolling me here :)
09:03 mcmillhj left
rightfold TIMTOWTDI. One way is to not use classes if you need no state. And if you do need state, use closures! 09:05
moritz you can use (multi) subs; their names at least are resolved at compile time 09:07
Woodi moritz: o, this is good to know 09:08
brrt Woodi: i don't think jnthn is often trolling 09:09
Pierre_ also, a more "normal use case"

09:12 darutoko left
Woodi brrt: problem evolved into: method rot1( "Buu" ); is not detected during compilation 09:12
jnthn Woodi: Not at all. That things interpreted in the current language (subs, multi subs, variables, operators) can be compile-time checked, and that things in an object's language (that is, method calls) are late bound, is one of the basic design principles of Perl 6. 09:13
09:14 cibs left
Woodi jnthn: when someone write his small script he know that he don't use MOPs and evals and just want syntax checking... 09:15
09:15 cibs joined
jnthn This isn't anything to do with syntax, though. 09:16
If you think it is, you don't undertsand the problem well enough for us to discuss this.
Um, that was a tad mean...I slept like crap. :P
Woodi jnthn: obviously I just looking for some new way around functional inventions :)
jnthn But really...the original idea of OO was late binding. 09:17
Or at least, one of them.
Woodi jnthn: possibly. will try to check my thinking, don't worry :)
jnthn userpage.fu-berlin.de/~ram/pub/pub_...kay_oop_en is a useful read :) 09:18
rightfold WTB "use Bla:from<PureScript>;"
jnthn (By Alan Kay, who coined the term OO)
rightfold PureScript compiler will have a feature to dump JSON of its IR soon so that will be super rad
brrt Woodi: my understanding is that you have a class that does or does not do some method, and you have a usage of an object of that class, and you'd like the compiler to check if that usage is correct 09:19
and what jnthn is saying is that the perl6 compiler can't do that, because it can't statically determine whether you are using the object correctly, because that is up to the object, and not to the compiler 09:20
Woodi let's just be sure that ideal OO will *not* be security nightmare...
brrt whereas with subroutines, the compiler /would/ be able to tell you, because subroutines are resolved by the compiler, and hence the compiler can check
i don't think security is the issue at hand here 09:21
Woodi brrt: see aobve: obviously I just looking for some new way around functional inventions :)
brrt Woodi: i can't parse 'functional inventions'
i don't know what you mean by that

robertle I think I understand the differend of "push @list, 2, 3;" vs "push @list, (4, 5);", but can I do the same with splice? I can do "splice(@list, 1, 1, (0, 1));" seems to do the same as "splice(@list, 1, 2, 0, 1);"... 09:22
Woodi for me, somehow late-bound is close to functional additions...

robertle I want to create unique IDs for things in a concurrent setting. I can of course just use an number that I increment and a lock to protect it from concurrent access, but is that the right way? seems heavy... 11:33

robertle ok, thanks. this is a module used by other code/trheads who should not need to know about the internals, so I would not want to burden them with the ID creation. is there a way to create a per-thread variable? TLS? all of this seems very low-level... 11:53

fritz_ Hi, we have an inquiry for a training course on Perl6 emphasizing differences between Perl5 and Perl6 (for Perl5 developers). I assume they are looking for a course in German. Who could do something like that? 12:41
12:46 pmurias joined
pmurias jnthn: will localref be used by rakudo in the future? 12:46
jnthn pmurias: Yes, once we get more aggressive at lexical -> local lowering. :)
(In fact, it's there to enable it.) 12:47
(Optimization note: it's a single-procedure analysis to see if a given local might be ref'd.) 12:48
(So if you need to code-gen them in some different and maybe less optimal way, it's not so hard to do that.) 12:49
12:51 sufrostico joined
lizmat fritz_: I could be persuaded to give such a course 12:57
I guess FROGGS or moritz or nine could do so as well, if not better, though :-) 12:58
fritz_ lizamt: Could you give it in German (I am not 100% sure, if this is a requirement)? The inquiry is from www.helmholtz-berlin.de/, if I have at least one potential volunteer I'd ask them if I should forward their eMail. 12:59

jkramer Ahoy 13:01
lizmat fritz_: to give you an idea :-)
jkramer I recently installed rakudo (view rakudobrew) on a new system and now it seems that modules are not recompiled when I run a script but some stuff from .precomp is used. 13:02
fritz_ lizmat: I guess I should have gone there after all ... ;-) ...
jkramer I guess it's smart for production but kinda annoying during development when I have to delete the .precomp directory whenever I change something. 13:03
Is there a way to turn that off?
moritz fritz_: feel free to shoot me an email (moritz.lenz@gmail.com) with details
fritz_ I will ask if I can forward their mail.
brrt fritz_: hemholtz centre is a research institute, correct?
cool
fritz_ Indeed. And being in Berlin I'd be very interested in going there, but just think it wouldn't be fair there being much more competent people around for giving such a course. 13:04
pmurias jkramer: by change something you mean change the modules source code, or moarvm internals? 13:05
jkramer pmurias: The modules source code

MetaZoffix jkramer: you're not meant to delete or turn anything off. It'll recompile on change
13:08 mcmillhj joined
MetaZoffix jkramer: there were a couple of recent commits that had a bug with that, but everything is fixed in HEAD. Ensure your version is at least 2016.08.1-182 or above 13:09

MetaZoffix jkramer: yeah, try upgrading. 13:11
jkramer :( That takes forever on that machine. Oh well, thanks :)
MetaZoffix You might need to delete .precomp once after upgrade, just to ensure the buggy precomp is gone.
RabidGravy "Is Term::ReadKey thread-safe", "er unlikely, how long have you got?" 13:12
MetaZoffix And after that it'll update automatically on change
nine MetaZoffix: note that I actually don't know why there seem to be issues on the first run after upgrading to the fixed version. It doesn't make sense as precomp files are bound to the very specific compiler build. 13:13
13:13 Sgeo_ left, rindolf joined
Ulti jkramer: if you are in production I would use rakudobrew with an actual release version rather than capturing a random HEAD state mid development it's usually quite stable but things like this are much more likely to happen outside of a tagged release 13:13
rakudobrew defaults to the very latest commit 13:14
MetaZoffix nine: ah. Well, I was just guessing. Didn't want jkramer to think the bug was still there if they upgrade but still don't see changes in the precompiled modules.

melezhik_ well, I need to have an array of all captured data, meaning all inside () 19:48
how can I do this?
jnthn Not sure I understand what you're trying to do. In your original example, hello wasn't captured... 19:49
melezhik_ ok forget about my previos example, it is probably not very good 19:50
all I need to get an access to all capured data
geekosaur $/ has all captured data
melezhik_ by captured data I mean only chunks inside () 19:51
geekosaur (or the result from a smartmatch against a regex has it, if you grab that)
jnthn Maybe .caps is what you want?
melezhik_ $/ give me all not only these chunks
moritz so, is it a problem to have more information available?
melezhik_ yes, this is problem 19:52
jnthn m: say ('abc' ~~ /(.)b(.)/).caps
camelia rakudo-moar 0cf712: OUTPUT«(0 => ｢a｣ 1 => ｢c｣)␤»
melezhik_ I need only a captured data
not matched data
as it works in perl5
I will try caps
jnthn Failing that, show how it'd be in Perl 5. 19:53
melezhik_ in perl5 it would be : my @foo = ('91hello92hello' ~ /\d+(\w+)/g); 19:54
say ('91hello92hello' ~~ m:g/\d+(\w+)/).caps 19:55
jnthn m: my @foo = ('91hello92hello' ~~ m:g/\d+(\w+)/)>>[0]; say @foo 19:56
camelia rakudo-moar 0cf712: OUTPUT«[｢hello92hello｣]␤»
melezhik_ gives - Method 'caps' not found for invocant of class 'List'
jnthn \w+ matches the hello also in Perl 5 though, surely?
uh
matches the 92 I meant
arnsholt It's a list of Match objects, each of which can be inspected to find what you want, presumably
jnthn But yeah, that's why I did >>[0]
Though easier might be
m: my @foo = ('91hello92hello' ~~ m:g/\d+ <( \w+/); say @foo
camelia rakudo-moar 0cf712: OUTPUT«[｢hello92hello｣]␤»

camelia rakudo-moar 0cf712: OUTPUT«[｢hello｣ ｢hello｣]␤»
arnsholt melezhik_: If you print the match object, it'll print the whole string that matched
*But*, that's just the stringification. The object itself contains *more* information than you have available in Perl 5
melezhik_ my @foo = ('91hello92hello' ~~ m:g/\d+(\w+)/)>>[0]; say @foo;
gives me a [｢hello92hello｣] 19:58
this is not what I need
jnthn Yes, I said that. 92 is matched by \w
arnsholt m: my @foo = ('91hello92hello' ~~ m:g/\d+(\w+)/); say @foo[0][0]; say @foo[1][0]
camelia rakudo-moar 0cf712: OUTPUT«｢hello92hello｣␤(Any)␤»
melezhik_ ok, guys, again I need to get all captured, ( not matched !!! ) data, please give me a code example how to do this ... 19:59
arnsholt Oh it matches wrong
m: my @foo = ('91hello92hello' ~~ m:g/\d+(\D+)/); say @foo[0][0]; say @foo[1][0]
camelia rakudo-moar 0cf712: OUTPUT«｢hello｣␤｢hello｣␤»
arnsholt There we go
jnthn We are, but your example is confused. \w+ matches all the way to the end of the string.
arnsholt @foo[0] is the match object for the first match (91hello), @foo[1] for the second match (92hello)
jnthn Because digits are matched by it
20:00 nadim left
jnthn afk for a bit 20:00
melezhik_ my @foo = ('91hello92hello' ~~ m:g/\d+(\D+)/); say @foo[0][0]; say @foo[1][0] works, but look abit uncofmortable for me though ... 20:01
you may get any example, in perl5 I just had a calling regexps mathching in a list context and it works 20:02
mst m: my @m = ('91hello92hello' ~~ m:g/\d+(\D+)/).map(*[0]); say @m.join(' ');
camelia rakudo-moar 0cf712: OUTPUT«hello hello␤»
mst melezhik_: seems pretty comfortable to me.
melezhik_ I wounder why I get an array of arrays?
mst you get an array of match objects 20:03
arnsholt The reason it's like this is that the Perl 6 regexes gives you *structured* matches
mst then applying [0] to a match object gets the first positional capture
spebern my @foo = '91hello92hello'.comb(/(\D+)/);
mst hence .map(*[0])
melezhik_ I would like to get a captured data as one demensional array, that is it ...
mst melezhik_: which I already demonstrated.
arnsholt Oh yeah, if you just want something dead simple like "everything that matches this pattern", you probably want comb
spebern++ 20:04
mst true
but the .map is not difficult at all
melezhik_ mst: your way seems abit weird for such simple thing too
mst melezhik_: that's because you're using the 'complicated thing' API
also, if you find .map weird, you're not enjoying perl6 properly yet ;)
melezhik_ mst: I am ok with map or what ever constuction when they are realy needed, 20:05
mst melezhik_: so use spebern's approach for simple cases, and mine for not-simple ones 20:06
ugexe m: my @foo = ("91hello92hello" ~~ m:g/\d+(\D+)/)>>.values; say @foo
camelia rakudo-moar 0cf712: OUTPUT«[(｢hello｣) (｢hello｣)]␤»
melezhik_ mst: I need to have a simple thing - an all captured data, that is it. I would not like to play with additional map constructions to get this , well **if it possiblle** , I would not like 20:07
cause for simple things I would expect a simple ways ...
so, probably .comb looks much better for me 20:08
mst melezhik_: yes, which is what we keep telling you to use for this case. 20:09
melezhik_: I'm not sure I understand what the problem is? 20:10
.comb for simple cases, match objects when you need match objects
mst suspects .comb may be fairly close to the map I showed internally, but sugar exists for a reason :) 20:11
melezhik_: also, remember, as soon as you're capturing two things in each match things immediately get more complicated
melezhik_ mst: not sure, but .comb way gives me this: 20:12
my @foo = '91hello92hello'.comb(/\d+(hello)/); say @foo;
mst yes?
melezhik_ [91hello 92hello]
not what I need
mst that's because you didn't do .comb the way we showed
melezhik_ I need ['hello','hello']
arnsholt comb extracts everything that matches
mst melezhik_: your \d+(\D+) example didn't need the \d+ 20:13
arnsholt Either use a look-around or use the Match objects
mst melezhik_: if your real problem is something different
melezhik_: please tell us what the real problem is :(
melezhik_ mst: I have already told you my real problem
mst .comb(/(\D+)/) would solve the example you gave.
if that doesn't work, then you haven't told us the real problem yet
please tell us the real problem :( 20:14
m: my @foo = '91hello92hello'.comb(/(\D+)/); say @foo;
camelia rakudo-moar 0cf712: OUTPUT«[hello hello]␤»
mst see, it works fine for the problem you gave us
melezhik_ mst: on my example .comb does not work please see my output 20:15
mst melezhik_: you changed the code and made it less simple.
melezhik_: that broke it.
El_Che mst: count to 10 :)
arnsholt Dude. You're clearly parsing something other than what you're showing
skids seeks shelter.
mst melezhik_: your example can be fixed by deleting the \d+ :)
arnsholt If you tell us what you're *actually* working on, we may even be able to help
melezhik_ mst: I don't want to delete \d
mst right. we need a better example of the problem
melezhik_ I need to keep them in my regex 20:16
mst melezhik_: well, that solves the problem you've shown us.
melezhik_: if it doesn't solve your real problem
melezhik_: please tell us what the real problem is
melezhik_ mst: I have already gave you an exmaple
mst your example is fixable by deleting \d+
that doesn't count
melezhik_ mst: please don't keep ask me this, as I already told you many many times
ugexe arnsholt | Either use a look-around # this is what you want
perlpilot m: my @foo = '91hello92hello'.comb(/<after \d+> \D+/); # here's a random guess at what melezhik_ wants
camelia ( no output )
mst melezhik_: if your data is really '91hello92hello' then we've solved your problem with .comb 20:17
perlpilot m: my @foo = '91hello92hello'.comb(/<after \d+> \D+/); say @foo; # oops
camelia rakudo-moar 0cf712: OUTPUT«[hello hello]␤»
mst melezhik_: if it isn't, please show us the real data so we can help
I don't understand why you don't want to let us help you :(
c'mon, all we need is an example where the \d+ or whayever actually matters 20:18
melezhik_ guys, again 1) arnsholt way my @foo = ('91hello92hello' ~~ m:g/\d+(\D+)/); say @foo[0][0]; say @foo[1][0] works fine but I found this abit complicated for such a simple thing as getting all captured data 20:20
mst melezhik_: yes, but .comb(/\D+/) works fine for that.
melezhik_ when I asked alternatives I was told a .comb way which does not work
mst melezhik_: it does work for that problem
melezhik_: if you have a different problem, we need the different problem
spebern what about perlpilot's way, still with comb
20:21 ufobat left
melezhik_ mst: please refere to docs.perl6.org/language/regexes#Capturing to see what I mean by capturing, I need data inside () 20:22
harmil_wk Is there a graceful way to override things defined inside of Perl6/Actions.pm? I'd like to wrap wrap_option_n_code, but I can't seem to find it from my code...
mst melezhik_: the problem you gave doesn't need that at all
melezhik_: that's why I'm asking for a proper problem :(
melezhik_ mst: you misunderstand my problem
mst melezhik_: well you won't tell me what it is.
melezhik_: the problem you gave does not need capturing 20:23
melezhik_: what problem do you have that actually needs capturing?
melezhik_: we can help you solve it if you'll tell us :)
melezhik_ ok , I have a string $foo = '91hello92hello' and I have a regexps m:g/\d(hello)/
I want to have a way to get all 'hello' captured chunks 20:24
mst: does it help?
mst melezhik_: no
melezhik_: because that problem is better solved by not using that regexp
melezhik_: and instead using .comb(/(hello)/)
melezhik_: that problem does not need captures :(
melezhik_ (I thought I had already formulate this so many times, but if you want this again, then please take a look )
mst harmil_wk: hrm, github.com/FROGGS/p6-Slang-Tuxic/b...g/Tuxic.pm shows overloading other bits
harmil_wk melezhik_: Does .comb ensure that the prefix digit will be there? 20:25
I think he wants that
perlpilot melezhik_: Did you try .comb(/<after \d+> \D+/); ?
melezhik_ mst: this is a input parameters of my task, I can't say what I need
perlpilot harmil_wk: aye, that was my earlier guess (but he never said it or why)
mst melezhik_: what?
melezhik_: how can you program if you don't know what problem the program is solving?
mst doesn't understand :( 20:26
perlpilot melezhik_: If you weren't writing Perl 6, I'd be thinking you're asking us to solve some homework for you.
melezhik_ mst: I stated my task, sorry, but I started to get bored of you repetious questions, if you can't help that's ok, I will find other ways
harmil_wk mst: sorry, I don't understand. Doesn't a slang override parts of the grammar specifically? How do I override specific functions inside of Actions that way?
mst melezhik_: I can help, if you'll show me a problem that needs captures 20:28
why do you, specifically, have to use a regexp with a capture
20:28 ZoffixMobile joined
mst unlike the .comb + after approach? 20:28
harmil_wk: I'm not sure, I was hoping that that might provide some hints where to poke around 20:29
arnsholt harmil_wk: What do you need to override the actions for?
If not because of grammar-related shenanigans?
mst harmil_wk: thinking that $MAIN-grammar in there might have an actions set that could be used or something
harmil_wk Actions.pm defines wrap_option_n_code which is the wrapping function for the -n flag. I want to wrap the wrapper
melezhik_ mst: regulars expressions are kind input data , well you can't change them, they get comipled programmatically by given rules, you can't changes these rules, one of possible cases is that one my use () for regular expressions
harmil_wk mst: Oh, fair point. I'll see if I can introspect that a bit. 20:30
melezhik_ this captures are not part of program code
ZoffixMobile melezhik, we have am article on comb: perl6.party/post/Perl6-Comb-It
melezhik_ does ot make a sence mst?
20:30 cdg left
harmil_wk arnsholt: Sorry, my comment about Actions.pm was directed at you. I should have said so. 20:31
mst melezhik_: and you can't change the compiler to generate lookahead/lookbehind patterns instead of () ?
melezhik_ Zoffix, I will take a look at comb, thanks
arnsholt harmil_wk: I figured it out =)
ZoffixMobile melezhik, it doesn't deal with captures, but with matches. you can use <( after the digit to indicate you don't want it
arnsholt So basically, you want to make another option like -n which is derived from it?
mst melezhik_: also, what happens if you have more than one capture?
harmil_wk arnsholt: frankly, it seems like a strange place to have that. I'm not clear on why it's not in main.nqp... 20:32
ZoffixMobile melezhik, it's one of the areas where Perl 5 method is more concise, because in Perl6 you get a tree of Matcb objects from a regex match, rather than just a basic list of captures
melezhik_ mst: not sure if I understand you last question ...
mst melezhik_: what if there is more than one () in the generated regex?
arnsholt harmil_wk: Because it does an AST transformation, probably 20:33
melezhik_ ZoffixMobile: I expressed EXACTLY what I try to asy
try to say
mst melezhik_: please stop shouting at people and keep answering the questions we're asking.
arnsholt Nothing stopping you from putting it in main.nqp (as far as I can make out, anyways), but since all the rest of the AST stuff is in Actions it makes sense to have it there too
ZoffixMobile melezhik_, yeah. The answer is you won't get it with a regex match. And 20:34
melezhik_ I just needed to know if perl6 has any ( perl5 like way ) concise way to get a captured data
ZoffixMobile .comb is likely a better solution
melezhik_ that is it ))))))
mst melezhik_: for the cases where you would use that in perl5, .comb is the answer usually
melezhik_: but, again - do you ever have more than one () in the regenerated regex?
melezhik_: please actually answer the question :(
melezhik_ mst: yes, it does, I may have more then one () in my regexps 20:35
mst melezhik_: right, then ($str ~~ m/.../)>>.values
melezhik_ basicly because this is not me, but external users which DO write such an expressions
mst melezhik_: as ugexe suggested
melezhik_: will be the right answer.
assuming you want ($first_capture_1, $first_capture_2, $second_capture_1, $second_capture_2) 20:36
i.e. flattened
melezhik_ mst: I don't shout at anybody
ZoffixMobile Would it really? Will that get nested captures?
melezhik_ mst: please don't blame me at what I have never done 20:37
ZoffixMobile: it was a typo, I meant "YOU expressed EXACTLY what I try to say" 20:38
ZoffixMobile heh :)
mst my @foo = flat ('91hello92hello' ~~ m:g/\d+(\D)(\D+)/)>>.values;
seems to get a flattened array of captures
or 20:39
ZoffixMobile what if you nest them?
mst >>.values.flat
ZoffixMobile the captures
melezhik_ Mst, ZoffixMobile now I see the ways. thanks I will examine them detaily later
timotimo you'll still get match objects, i guess?
mst then I ... I don't even understand what's happening
ZoffixMobile Yeah, my guess too. Maybe deepmap or whatever it is is needed 20:40
mst I've only read the docs end to end once so far
you seem to get a match in $match[0] ?
melezhik_ mst: do you see now what I tried to ask? or you still feel I don't give you a right example or I don't answer you questions? 20:41
mst melezhik_: once you explained the regexps were generated and could have more than one capture, I was able to help
ZoffixMobile m: dd 'foo' ~~ /(f(o(o)))/ 20:42
camelia rakudo-moar 0cf712: OUTPUT«Match.new(ast => Any, list => (Match.new(ast => Any, list => (Match.new(ast => Any, list => (Match.new(ast => Any, list => (), hash => Map.new(()), orig => "foo", to => 3, from => 2),), hash => Map.new(()), orig => "foo", to => 3, from => 1),), hash => Map…»
melezhik_ mst: ok
mst melezhik_: that was a perfectly fine answer, it's just it would've been quicker if you'd said that the first time I asked :)
ZoffixMobile Speed is not the name of the game. 20:43
ZoffixMobile & 20:44
20:44 ZoffixMobile left
melezhik_ ok, I was trying to reformualte my question , at least I feel so, but you kept sayining that maybe I don't need a captures, that I was confused ... 20:44
mst melezhik_: because your original problem didn't need any. only when you told me (a) the regex was generated (b) it could have two sets of (), did you give me a problem that did need captures 20:46
ugexe if you're using arbitrarily deep nested unnamed regex matches to create an ordered list you're gonna have a bad time
mst melezhik_: the outside constraints of your problem are important to finding the best solution. next time please tell us -why- you're doing something, it'll be much easier that way 20:47
dj_goku anyone ever use Proc::Async as a Command Runner for Shell commands? vs a serial copy and paste.
mst also, it may be we can introduce you to a new part of perl6 that makes the problem go away :)
melezhik_ yeah. mst: but when I gave an example, it was only an example of generic issue, ok I will try to bring more details at the start of my next questions, but in other side sometimes one should not treat an examples as concrete task to solve 20:48
mst the problem was that you gave an example best solved without captures
melezhik_ at least for some cases it's not a good approach to help , IMHO
20:48 kaare__ left
mst which is why I asked for a better example 20:48
I don't mind people using examples of the problem, but they have to be examples of the problem. examples of a much simpler and different problem don't help :) 20:49
melezhik_ mst: yeah, I see your point, at least now, we are ok, are not we?
mst melezhik_: I've always been fine. I just wanted to actually solve your problem :) 20:51
melezhik_ mst: I asked just in case :)
harmil_wk Is there a way to access a sub that's defined within a class from an instance of that class? (not a submethod, but an actual "sub")
melezhik_ I will examine, map, values and comb ways I will let you guys know in case I have further help 20:52
thanks!
Zoffix melezhik_, do you care about named captures as well? $<foobar> ?
mst harmil_wk: subs aren't actually defined within a class, they're actually defined within a scope - they're lexical
melezhik_ Zoffix: no, I do not need a named captures ...
mst the block they're in might incidentally be a 'class ... {' block but so far as I can tell it's all the same to the subs 20:53
ugexe m: class Foo { my sub bar { say 666; }; method foo { &bar(); } }; Foo.foo # ?
camelia rakudo-moar 0cf712: OUTPUT«666␤»
perlpilot harmil_wk: have a method on that class that's defined within the same scope as that sub call the sub. (what ugexe said) 20:54
