perlawhirl hi perlers 07:39
07:40 pharv joined
perlawhirl i been playing around with different combinatoric sequences 07:40
i have an issue with one of my functions that generates the next sequency by modifying positional elements in an Array (or List) 07:41
and the gather/take, when evaluated eagerly, only gives me the last entry
gist.github.com/0racle/6be868d7ef3...9b24387299
this is golfed
but how do i work around this?
as mentioned, this is golfed... it's the rotating of positional elements (@list[*]) that does it... if i simply did `@list .= rotate` it doesn't happen 07:42
AlexDaniel .tell Zoffix re run, «» and notifying users about their bugs: I feel encouraged by your attempt to work on the issue on case by case basis… Lately I feel like it's easier to give up :) irclog.perlgeek.de/perl6/2018-01-24#i_15732558 07:44
yoleaux AlexDaniel: I'll pass your message to Zoffix.
perlawhirl but in my function i'm reversing a portion of the list (eg. `@list[$k..$n] .= reverse`) and i can't seem to make it work right when consuming the seq eagerly

perlawhirl Zoffix: I understand why your code does what it does, but don't immediately see why the gather/take acts this way 08:28
just so i understand it, when eagerly evaluating the gather/take, does it do the equivalent of your `@b[n] = @a` until the gather ends, then returns `@b`
and if that's the case... whats the best way around it, given that i'm generating a sequence by modifying a list in place 08:29
hrm... so a "quick fix" for my actual code is rather than `take @list[^$k]`, I can do `@a = @list[^$k]; take @a.clone`. 08:33
feels a bit messy, but helps illuminate the issue for me
moritz try @list.head($k) 08:35
08:38 Zoffix joined
Zoffix perlawhirl: no, @b.STORE pulls each of the items from the Seq created by gather/take and sticks into a new element in @b, one at a time. Each time it generates a new element, *all previous elements* of @b are too updated, since they all contain the same object. But by the time you **print** the eager version, the Seq was already fully pulled and all of the cells on @b contain the same @a Array that it's in its 08:42
last rotation. In the lazy version, the Seq is pulled **while the Str for printing is made** so despite the same Array being used for everything, by the time it changes on next iteration a Str snapshot of it was already taken

perlawhirl: but please submit a ticket with this particular case 11:41
perlawhirl What I find odd (or I just don't understand) is I can define my own pure sub, export it from a module, and it doesn't suffer the same issue. It identifies (.WHAT) as a Sub+{is-pure}, but i can assign it to a &callable just fine
ok.. will submit GH issue

Fixes the last "return Any"

By looking at the actual implementation. Revised also other "returns empty list". It actually returns an empty list in many cases, so it's OK. I haven't seen any other remainint, so provisionally closes #1731. If anyone finds a particular description that's wrong, I would rather have an specific open issue for that.		 13:50

Manifest0 so without a space is a function call and with is an anonymous call? That's going to be confusing... 16:40

timotimo aye, just like when you write "if($foo = 10)" that's not an if statement, that's a call to a sub called "if"

jdv79 m: use Test;like(IO::Path.new("."),/\./) 17:20
camelia IO::Path is disallowed in restricted setting
in sub restricted at src/RESTRICTED.setting line 1
in method new at src/RESTRICTED.setting line 32
in block <unit> at <tmp> line 1
jdv79 nice
anyway, the docs for Test::like say i coerces so what gives? 17:21
"Marks a test as passed if the $value, when coerced to a string, matches the $expected-regex. "
IO::Path::Str exists
Juerd Either the documentation or the implementation is wrong 17:22
It does not coerce. It even handles non-Str separately. 17:23
jdv79 i see that. its not in S24 so i guess its up for grabs 17:26
but timotimo - why did you make that change? the docs look correct before your change
timotimo i did?
jdv79 github.com/rakudo/rakudo/commit/ba...c9903bf1c3 17:27
maybe that should have been more like if it can't stringify then kick?
timotimo hm, i think the problem you mentioned was in the code before i changed things 17:28
like the commit message mentions, i had test code like "create an array, then call `like` on the different entries"
and it used to bring down the whole test suite if there wasn't an entry at one of the locations
jdv79 it used to be just: $got ~~ $expected
which would have wrked 17:29
timotimo ah, i see
feel free to turn it into Str() then
jdv79 ok

Kaiepi never mind, looking at the coredump it's the same problem that's breaking some other native stuff on my system 19:43
MasterDuke rindolf: i asked him the same question yesterday, he had some info irclog.perlgeek.de/perl6-dev/2018-...i_15853760 19:44
timotimo rindolf: did you read backscroll? 19:45
ah, thanks MasterDuke
note, however, that i do get a different result after i made that change :(
so clearly some result in the middle passed the 64bit range

MasterDuke hm. wouldn't perl5 also have problems if intermediate values are getting bigger than 64bit? 20:00
rindolf MasterDuke: see github.com/shlomif/project-euler/t...-euler/618 20:01
MasterDuke: i think so
MasterDuke huh. i guess they don't get quite big enough to actually break things 20:04

rindolf MasterDuke: i am getting the same result from pypy3 and from p5
MasterDuke i think timotimo has contributed to pypy in the past 20:09
rindolf MasterDuke: on a core i3 machine
El_Che: yes
timotimo a tiny bit 20:10
pypy is fantastic
El_Che timotimo: does it fix the GIL thing? 20:11
timotimo: how is it that fast btw? regular python is also C 20:12
sounds interesting
rindolf El_Che: pypy has jit and stuff like that 20:13

MasterDuke huh, making all variables ints, including the arrays, makes it slower 22:11

MasterDuke not by much, but i would have expected some sort of speedup instead 22:14
22:14 cdg joined 22:15 martinp2 left
rindolf MasterDuke: perhaps we can use bit vectors 22:15
like vec() in p5
timotimo MasterDuke: that's what i was writing about, though; split the expression with the two array accesses into multiple lines, each assigning into a native int var, then it'll be faster 22:17
MasterDuke wait, this is weird. why does my profile of the unmodified code show 45641 calls to calc_S?
i just stuck 'int ' before every variable declaration 22:18
22:19 cdg left
timotimo yeah, it looked like that somehow incurs a whole lot of boxing and unboxing or something 22:20
MasterDuke must be, it was still using the Int, Int candidate for infix:<%> 22:21
pmurias if there are precompiled files in a path passed to -I rakudo should also find them? 22:29
MasterDuke and how does postcircumfix:<[ ]> have so much exclusive time when all it does is call AT-POS?
timotimo fwiw, in the fastest version i had, it was somehow still using the exact same line number for infix:<%> but even with the same number of calls it was significantly faster 22:30
so .. ?!
