| pmurias | what's the state of the test functions in the Prelude proposal? | 09:50 | |
| wayland76 | Anyone know which synopsis I need to read if I want to make my *own* iterator? | 09:52 | |
| masak | wayland76: sorry, no. have you tried grep'ing the synopses? | 09:53 | |
| pmurias | ack is better than grep | 10:11 | |
| wayland76: gather maybe be what you are looking for | 10:12 | ||
| masak | pmurias: aye. I just wish I could prevent it from spewing ANSI colour codes, so I could use it from within Emacs | ||
| pmurias | use --nocolor or RTFM ;) | 10:13 | |
| masak | good idea :) | ||
| masak makes the appropriate alias | 10:14 | ||

| masak | pugs: say map {[*] map { $_ * 10 }, [1..$_]}, [1..5] | 10:23 | |
| p6eval | pugs: OUTPUT[50ā¤] | ||
| masak | that's gotta be wrong | 10:24 | |
| pmurias | pugs: map { $_ * 10 }, [1..$_] | 10:37 | |
| p6eval | pugs: RESULT[(0.0,)] | ||
| pmurias | pugs: map { $_ * 10 }, [1..1] | ||
| p6eval | pugs: RESULT[(10.0,)] | ||
| masak | I don't know if I agree with the first one, but certainly the second | 10:38 | |
| pmurias | pugs: map { $_ * 10 }, [1..5] | 10:40 | |
| p6eval | pugs: RESULT[(50.0,)] | ||
| pmurias | masak: pugs is correct in the example you give | 10:41 | |
| masak | please explain. | 10:42 | |
| pmurias | an array in numeric context turns into the number of elements | 10:45 | |
| map {[*] map { $_ * 10 }, [1..$_]}, [1..5] turn into | 10:46 | ||
| [*] map { $_ * 10} [1..5] | |||
| which turns into [*]([1..5] * 10) which turns into [*] 50 which turns into 50 | 10:47 | ||
| masak | what forces numeric context? | ||
| pmurias | [1..$foo] and $foo * 10 | ||
| masak | is there a version of my expression that does what I mean? | 10:52 | |
| wayland76 | >which ack | 11:20 | |
| -bash: type: ack: not found | |||
| Yeah, I've been looking at gather/take | 11:21 | ||
| But I want to iteratively walk through a tree... | |||
| So I need the gather in one function, and the take in another | |||
| Can I do that? | |||
| masak | wayland76: search.cpan.org/~petdance/ack-1.86/ack | 11:22 | |
| wayland76: yes, you can | |||
| lambdabot | Title: ack - grep-like text finder - search.cpan.org | ||
| masak | wayland76: a gather is dynamic | ||
| this works in Rakudo already, since take works using exceptions | |||
| wayland76 | Ok, great :) | 11:23 | |

ruoso joined
|
|||
| wayland76 | Yeah, I see ack (thanks). But I'm planning to upgrade my Fedora as soon as the new one comes out, so I won't install it now :). But I've bookmarked it. | 11:26 | |
| ruoso | wayland76, iterators are under-specced at the moment... | 11:33 | |
| wayland76 | ok | 11:34 | |
| Are iterators a role I should implement? | |||
| Should I be overriding particular functions on that role? | |||
| ruoso | it probably will be a role, yes... | 11:35 | |
| the method is prefix:<=> | |||
| which 'fail' at the end of the iterator | 11:36 | ||
| if you're implementing a plain iterator that always return one item at a time, no matter in which context, that's fairly simple... | |||
| there are other iterators that support slice context, like the iterator returned by map | |||
| they are a bit more complex | 11:37 | ||
| wayland76 | Ok, that gives me some idea of what to do. | 11:40 | |
| Now I just wish for power loops :) | |||
| ruoso | you might want to look at the smop map wiki | ||
| wiki page, I mena | |||
| *mean | 11:41 | ||
| wayland76 | IKWYM | ||
| ruoso | wayland76, "power loops"? | ||
| wayland76 | (I know what you mean :) ) | ||
| Yeah, it's a sort of iteration/recursion thing. I'll find a page. I read about it somewhere esoteric :) | |||
| www.nondot.org/sabre/Mirrored/AdvPr...nkel02.pdf | 11:46 | ||
| Near the end | |||
| I have the book of that PDF, btw :) | |||
| lambdabot | Title: cache:www.nondot.org/sabre/Mirrored/AdvPr...nkel02.pdf - Goog ..., tinyurl.com/y39uw5 | ||
| pmurias | wayland76: any way gather/take is the thing you should propably use, you should mind about Iterator role if you want to something internalish | 11:47 | |
| wayland76 | pmurias: Agreed. Maybe I'll just code the thing now; it should be easy enough to include the iterator role later if I want :) | 11:49 | |
| pmurias | ruoso: hi | ||
| ruoso | hi pmurias | 11:50 | |
| wayland76 | (oh... hi everyone :) ) | 11:54 | |
| Which part in particular of the SMOP page, now that I've found it? | |||
| ruoso | pmurias, I've been thinking at which point we should stop extending libsmop and start to think about effective runtime... | ||
| www.perlfoundation.org/perl6/index....p_operator | |||
| pmurias | effective runtime being? | 11:55 | |
| ruoso | pmurias, ok, that didn't sound right... | ||
| pmurias, smop is a library so far... we need an actual interpreter | |||
| one that defines $*IN and $*OUT, for instance | 11:56 | ||
| that knows how to look for libraries, that kind of stuff | |||
| pmurias | so what we need is some sort of executable which can read in m0ld and perl6 and run it? | 11:58 | |
| ruoso | yeah... exactly... | 11:59 | |
| it might even be written in Perl 6 | |||
| ;) | |||
| and compiled down by mildew | |||
| wayland76 | ruoso: Wow, thanks :) | 12:00 | |
| ruoso | wayland76, you might want to look at the map and grep tests in the smop repo | 12:01 | |
| wayland76, smop is the first to support lazyness in map and grep | |||
| wayland76 | Cool. I think I just want to use the Iterator role for now | ||
| I'm attempting operator overloading, so it's not like my code compiles now (at least in rakudo, which is what I'm using at the moment) | 12:02 | ||
| ruoso | wayland76, but remember that is not part of the specs (at least not yet) | ||
| wayland76, and it's certainly not rakudo-oriented... | 12:03 | ||
|
12:03
zamolxes left
|
|||
| wayland76 | Sure, I agree. But the logic of the situation presumably demands a similar solution | 12:03 | |
| so if I write my code, I'll probably only have to change the function names and things :) | |||
| ruoso brb & | 12:04 | ||
| pmurias | ruoso: is it decided yet how binding works? | 12:07 | |
| pugs_svn | r22503 | pmurias++ | [smop] added a test for the pure prototype HOW in p6 to be compiled by mildew | 12:12 | |
| r22503 | pmurias++ | (dosn't run or compile yet) | |||
| r22504 | pmurias++ | [STD] added $foo.^!bar() | 12:18 | ||

| wayland76 | Is there an easy way to do have it so that when I call a function on an object, it run somthing like { ancestor setup code } {descendant code } {ancestor cleanup code} ? | 13:34 | |
| If $axes is an iterator, and $usetest is a Matcher function, and I've defined a prefix:<=> on my iterator, can I do this... | 13:43 | ||
| @nodes ==> map { =$axes ==> grep $usetest; }; | |||

| masak | wayland76: your first question sounds like ordinary delegation to base class methods -- no problem, in other words | 13:55 | |
| I'm very doubtful about your code example, even though I think I know what you're getting at. can't tell if what's within the braces is legal Perl 6 or not | |||
