perlawhirl the Download links at moarvm.org/releases.html do not work 00:20
MasterDuke for doc code samples that die/throw at runtime, not compile time, should we use something other than the <compile time error>, or does that mean the compile time of the docs, not necessarily the compile time of the example?

skids I think that test is dubious. It is supposed to test that it is a list assignment, which it is. Autivivifying an array into a scalar due to a @ prigil... should that really happen? 00:34
(and there's a similar test with $a[])

mcmillhj Which one of these is more idiomatic: "abc".comb() or "abc".split("", :skip-empty)? 00:40
00:41 mcmillhj_ joined
skids .comb is not obscure, it is used fairly commonly. 00:43
.split only if you are trying to write code readable to people who don't know Perl6. 00:44

perlawhirl I would hazard a guess that most of those `split`s are splitting on a delimiter, and that most `comb`s are not... but i could be wrong :D 00:54
mostly it's about intent. one of these conveys intent more clearly:
'this-and-that'.comb(/\W/) -vs- 'this-and-that'.split('-')
the split makes more sense as that's the intent of the result. 00:55
but for iterating or enumerating the chars of a string... `comb()` all the way 00:56
erm... there's an error above... i meant: 'this-and-that'.comb(/\w+/)
skids i dunno I think there is just as valid "intent" argument for .comb in that case. 00:57
perlawhirl i guess it depends on the context, yes
AlexDaniel I'd say the intent is even more clear with comb… 00:58
perlawhirl interesting to note... in those examples, split produces a Seq, comb produces a List
skids however, .comb(','?<(<-[',']>)>','?) would be a bad intent expression
AlexDaniel perlawhirl: your rakudo is old, it seems 00:59

lookatme Is someone well know cp :) 06:51
I want track the cp progressing, and I found -v is helpful option 06:52
But when I catch the stdout of cp, it can not get anything before copying over :( 06:53
And seems like other linux command also faced this problem
such as
cp -v xx yy /dir | more
cp -v xx yy /dir | cat 06:54
It didn't print anything before copying finished
geekosaur lookatme, that is output buffering. take a look at the stdbuf command, or consider using something like the script command 07:00
if you capture standard output to a file or pipe, the convention is to switch to block buffering, usually with a 4k or 8k block sie
size

lookatme yeah, it is okay now 07:28
jmerelo lookatme: great :-)
lookatme yeah, I just want get size of the file
so don't want create a IO::Path or some other object
jmerelo lookatme: if you allow me a suggestion, wouldn't "Advanced" be better than "Advance"? 07:29
lookatme where?
jmerelo lookatme: an option would be to use posix functions through the nativecall interface. Nqp is not really intended for human consumption...
lookatme: in the module name. 07:30
lookatme oh
maybe, but I have to modify a lot of things if I change the name 07:31
07:31 mcmillhj left
lookatme anyway thanks for your suggestion, my EN is not good :) 07:33
I think it's worth to using nqp if we need better performance 07:34
When I write my app github.com/araraloren/perl6-app-findsource, it is slowly when using IO::Path 07:35
Of course, I am hope some day I can using IO::Path instead of it :) 07:36
07:39 mcmillhj joined, robertle joined
jmerelo lookatme: the problem with NQP is that it does not have any kind of stable interface; it might change at any moment. It might be faster, but the functions, their name, functionality, might change or disappear. That's why it might be better to use NativeCall. Stable, solid interface, machine-line speed. 07:39
lookatme jmerelo, yeah, that's true 07:40
jmerelo lookatme: check it out here github.com/perl6/nqp#using-nqp

ufobat is there a way to convert a perl5 regex into a perl6 regex? 10:08
El_Che I know there is/was a perl5 mode, but I don't know if it works well (heard iti didn't) 10:09
jnthn rx:P5/.../ will parse it as Perl 5 syntax 10:10
As to how well it works: depends what features you're depending on.
ufobat cool 10:12
but there is not other way round, i mean, assuming you have a p6 regex in a $variable and you want to bring it to perl5? 10:13
lizmat no: the P5 adverb just changes the parsing: if the p6 regex is in a variable, it's already parsed 10:15
timotimo you do get the source string of the regex, though, don't you? 10:16
you could re-parse that into a QAST and transform it at that level
though it might be difficult if you have things like nested captures and backreferences and such, and even trickier if you have subrules that you call
ufobat but that sounds at least possible :-) 10:17
i put this on the last position of the todo list for my sereal module
ty :9 10:18
El_Che ufobat: you have a million line code base in perl6 that you automatically want to convert to perl 5? :)
ufobat maybe you can just convert very basic things 10:21
i dont know
sereal is quite perl5 specific 10:22
there are other things that doesnt match perfectly into p6, i think 10:24
jmerelo Re: creating new tags in StackOverflow. A bunch of us can do that, and now the pace of new questions seem to be picking up enough to merit being more specific. I was thinking about creating the "zef" and "cro" tags. What do you think? 10:26
jnthn jmerelo: Hm, I hadn't realized they had to be explicitly created; the Cro docs actually suggest people can get help by posting questions tagged "perl6" and "cro" on SO. :) 10:31
El_Che hehe 10:39
are only admins allowed to create tags?
jmerelo jnthn: That means that it probably exists already...

jmerelo jnthn: you do now :-) stackoverflow.com/questions/tagged/cro
jnthn Hm, if it's only 1500 I probably can create it :)
ah, you did it :)
jmerelo jnthn: I did create the tag, but it's got to be filled up, it's got no usage guidance. You can probably help with that :-) 10:42

jmerelo You probably know, or don't, that while I'm doing the TPF grant I'm staying at home 3 days a week, to focus on the stuff. While I'm doing that, I'm also cooking for the whole family. 15:57
Baseline is: I'm cooking. And there was a desert competition today in the CS Faculty where I teach. So I cooked this jj.github.io/manzanachos-con-natamole/ 15:58
Well, it's in Spanish, but it's basically a riff on the nachos with guacamole, only sweet. nachos become sweet apple and cinnamon chips, guacamole is still guacamole, but honey and vanilla and a bit of lime zest for color instead of garlic. 15:59
So I won.
Only two competing deserts, but what the hell, I wasn't second.
Anyway. I'm telling you this because if it weren't for the Perl Foundation, I would be going pretty much every day to my office, not cooking for the family, not learning to cook, and so on. 16:00
So this is kind of a collective thanks :-) And an offer to cook a few for the next Perl meetup, if anyone's interested. Apple chips are (obviously) vegan, natamole is not. Maybe for the next London Perl workshop :-) 16:02

[Coke] ..I know what a REPL is. you said there's no such thing. 16:58
which seems demonstrably false.
jmerelo [Coke]: OK, fair enough.
moritz I think jmerelo's sentiment was that you shouldn't look for special REPL tools to solve your problems 16:59
jmerelo moritz: that's what I meant. Thanks :-)
moritz instead, ask yourself "how would I do it outside the REPL?", and then reuse that solution inside the REPL
jmerelo moritz: correct.
comborico1611 The opposite method is done with Lisp, working inside REPL to apply to outside. I think. 17:00

but the warning got to me :)
C modules seem to break from time to time 20:02
maybe a module variant is needed per version? Readline::v5, Readline::v6, Readline::v7. On the other hand, a lot of users will have no idea which to install 20:04

b2gills Is there anything you are having trouble figuring out? 22:45
hythm_ Why it does not parse if the "space" placed before 'b' ,,, and only works when the space is inside <?after <a> > 22:46
22:47 kurahaupo_ is now known as kurahaupo
timotimo the "significant whitespace" stuff allows you to have whitespace after the opening { of the rule declaration without having it actually count as a space 22:47
so rule a {'a'} and rule a { 'a'} are equivalent 22:48
