Herby_ found a small task at work today that I'm going to use Perl 6 for. Have a list of 1000+ names and I need to find the ones that have any "non-word" character. 01:03
Figured I'd start small :)

that github issue reminds me once again that it is a good idea to have a mirror on bitbucket 02:01
or gitlab, or everywhere at the same time
because why not
git is distributed after all 02:02

Perleone I run Ubuntu 14.04 LTS with gcc version 4.8.4. Upon "rakudobrew build moar 2015.12" I get several warnings like these: travis-ci.org/cygx/p6-native-libc/...34517#L217 10:11
10:12 itaipu joined 10:13 ely-se joined, yeahnoob left
timotimo what kind of machine is that? 32bit machine? 10:16
geekosaur I think that's still right on 32 bit? my recollection is this kind of thing is mostly because windows 64 bit requires (long long int) for 64 bit values, and doing The Right Thing is annoying 10:19
Perleone timotimo: No, 64 bit kernel and userland. 3.13.0-74-generic #118-Ubuntu SMP Thu Dec 17 22:52:10 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux 10:20
The build itself runs successfully. It's just that the warnings annoy me somewhat. :)
geekosaur so the warnings are technically correct because (long long [unsigned] int) is allowed to be 128 bits, but in practice it never is, and otherwise it's hard to deal with win64 :/ 10:21
sadly, it's often the case that portability means you take some warnings, because pedantically correct means nonportable 10:23

term *or* an infix 18:21

moritz anthk_: please show a minimal, runnable example that produces the wrong value
timotimo so with +< 8 you'd just shift the number of elements in the list to the left
and that'd probably give you the same result every time
moritz try to say @memory.perl
anthk_ too long to post, moritz 21:21
[Coke] so, one of your assumptions is wrong, if you can't reduce the code required to duplicate it, and you can't use the samples provided above to help, I'm not sure what else can be done. 21:22
I would dump your data right before the offending section with .perl so you can see exactly what it is you're operating on.
moritz anthk_: that's why I'm asking for a *minimal* example
[Coke] then you can move that into a short example where you set a variable to that .perl output, and run the one line and dump the results. 21:23
moritz anthk_: fill the array with constants; if that makes the problem go away, the array contents aren't what you think they are
[Coke] We need to put together a "how to ask for help so we can help you" doc.
moritz anthk_: when you try to golf the problem to something smaller, you usually stumble about the actual problem very quickly; if not, we have a minimal example to run and examine

sortiz anthk_, in generañ you don't need that. Why are you using a Buf in the first case? 21:42
anthk_ the memory is composed of the contents of a file 21:43
I've just used ' while not $fh.eof {memory[$PC + $i] = $fh.read(1);$i++;} ' 21:44
ZoffixWin Interesting. The above bug only affects the 64 variant :/
anthk_ that's just the raw contents of the file, byte per byte

lizmat ok, I wonder what the opinion is about subclassing Date / Set / Bag / other composite builtin types 23:26

I think in general it's really useful to be able to do that. 23:27
lizmat I wonder what TimToady thinks about that
japhb Actually, come to think of it, here's my exact invocation:
class BusinessDate is Date does BusinessDateish { }
BusinessDateish being a role that adds four new attributes and a pile of methods. 23:28

class BusinessDateTime is DateTime does BusinessDateish { }

lizmat ZoffixWin: you're mixing up Bags and Mixes :0)
ZoffixWin Ah :D
Hotkeys Doesn't work timotimo, just makes it angry
timotimo oh 23:42
too bad
lizmat m: my @a = <foo bar baz>; say @a.grab # too bad, would make sense to me
camelia rakudo-moar 780192: OUTPUT«Method 'grab' not found for invocant of class 'Array'␤ in block <unit> at /tmp/BSf9IFHGVc line 1␤␤»
timotimo should we perhaps allow that?
pick and roll to accept WhateverCode?
Hotkeys Seems reasonable
ZoffixWin m: my @foo = 1..10; @foo.splice: @foo.elems.rand, 1; say @foo; 23:43
camelia rakudo-moar 780192: OUTPUT«[1 2 4 5 6 7 8 9 10]␤»
timotimo you sure you want .rand?
only works because it casts to Int, eh?
lizmat perhaps rakudobug it so it won't fall through the cracks
timotimo too lazy :)
distracted*
ZoffixWin m: 5.rand.say
camelia rakudo-moar 780192: OUTPUT«4.0167080428932␤»
ZoffixWin eh :) it works :)
sortiz pick uses rand.floor 23:46
23:46 bpmedley left
timotimo oh 23:47
well, yeah
23:47 bpmedley joined, bpmedley left, bpmedley joined, vendethiel joined 23:51 addison_ joined 23:54 SCHAAP137 left
ZoffixWin m: my str $foo = "bar"; $foo = "42"; say $foo 23:57
camelia rakudo-moar 780192: OUTPUT«42␤»
ZoffixWin What's the difference between str and Str?
perlawhirl m: my str $foo = 'bar'; $foo.WHAT.say 23:58
camelia rakudo-moar 780192: OUTPUT«(Str)␤»
perlawhirl seems nothing
lizmat str is native string, Str is a HLL string 23:59
perlawhirl ahh of course... lc types are native
