camelia (Bar)
Zoffix Seems to work if you don't have any :: in the name... I gotta have ::s
sub EXPORT is an excercise in frustration.

Zoffix It exports it as "Ber" -_- wtf
Success when will there be another nonjvm perl 6 00:56
Zoffix Success: you mean other than MoarVM?
Success thanks zoffix 00:57

camelia (Bar)
Zoffix I guess I'll just use that
Success where are the rakudo moar binaries 01:05
timotimo if you've installed a rakudo including the moar backend you'll have a perl6-m script, and usually the perl6 symlink points at perl6-m 01:30
Success i mean where do i download them

Zoffix Success: MoarVM is the default and preferred VM for Perl 6. 2017.10 and .07 .msi *are* available on rakudo.perl6.org/downloads/star/ They just don't have "moar" in their names. 01:41
Success ohh okay thanks zoffix that'll save ALOT of time :) 01:42
timotimo oh, i thought you wanted to compile because you wanted to compile
Zoffix Success: FWIW there are mostly-copy-pasteable build instructions here: github.com/zoffixznet/r#windows
timotimo sorry, i didn't realize
Success it can install to paths with spaces, right? 01:44
timotimo, oh i do, but it'd be nice to just have the binary in the meantime :p
Zoffix Success: good question :) ... I vaguely recall a bug with spaces, but it might have been fixed

Success oo that site is cool ty 01:47
Decoder.c took forever (moarvm) yikes 01:48
Zoffix 5 hours ago I started writing a config module so I could patch ZScript with a command to rsync my local rakudo changes to my 24-core VM, so I could save a few dozen minutes off running stresstests. 01:49
I've just finished with the module... Something tells me I'm not winning any extra time savings here :)
Success i love rsync tbh
haha it'll be worth the overhead :)
Zoffix Success: weird. MoarVM compiles on my Win10 box in under a minute
Success also are you on gentoo?
Zoffix Bodhi Linux 01:50
Success what flags and setup on your win10
Zoffix huggable: rakudo win
huggable Zoffix, perl Configure.pl --gen-moar --gen-nqp --backends=moar & gmake & gmake test & gmake install
Zoffix I just use that
in rakudo (and it builds moarvm)
Success ah
perl Configure.pl --os win32 --shell win32 --toolchain msvc --compiler cl & nmake 01:51
i don't think it's utilizing my intel compiler either :'(
timotimo huh, i didn't know any of those flags were accepted by Configure.pl 01:52
and that is why they keep me away from the build system :)

AlexDaniel, Log and stats: gist.github.com/220ac7af2f324a04f6...b5d4d6d821
kyan What's the difference between a Match resulting from calling parse() on a grammar, and a inline Pair like this? github.com/masak/xml-writer/blob/m...example#L5 04:04
I'm trying to use XML::Writer to print out the parse tree for a string.
If I just do XML::Writer.serialize($parsed) or XML::Writer.serialize($parsed), it says "The XML tree must have a single root node", even though the grammar match as far as I can tell does only have a single root. 04:05
geekosaur a Match is a very different thing. but using .gist doesn't show you the actual Match 04:06
("say" calls .gist for you)
try explicitly using .perl on it to see what it really looks like
kyan Oh, that looks *very* different, yeah. 04:07
What is the right way to go about getting my parse tree out into XML? 04:11
geekosaur that I wouldn't know offhand since I don't know what you are starting with 04:12
kyan calling .tree() on the Match still doesn't seem to be in the same format as the thing in the XML::Writer example
I'm starting with a Match object.
(well, at this point of the process. Originally I start with a string and a grammar, then I use the grammar to parse the string, and that gives the Match.) 04:13
If I run "say $parsed.tree;", it prints out a tree that looks like the XML I'd like to get out. 04:16
e.g. gist.github.com/ethus3h/7ce684c7d1...d849e589ba
geekosaur yes, and that's a bunch of nested Match objects instead of an actual XML tree 04:19
not sure offhand how you'd auto-extract that to something useful 04:20
kyan Ah... is there a better way to get XML or a normal tree out of a grammar?

Zoffix Is there a way to "eval" a QAST tree in HLL to see what it does?
like above would be like running `die "meow"`; or rather a crash saying can't stringify it, but it'd be die "meow" if you write the missing part right 09:20
moritz Zoffix: I'm not aware of how it works; you'd have to check how rakudo itself does it 09:28
but you might need a reference to Perl6::World too

timotimo hey, so, off-topic question: i've opened a drive with "cryptsetup luksOpen" and the block device that belongs to it shows up in /dev/mapper, but the individual partition block devices are missing and pvscan and vgchange don't find the pv's in them, unsurprisingly 14:27
gparted sees the partitions i'm looking for, though
DrForr linkbait://theperlfisher.blogspot.ro/2018/01/tree-surgery.html 14:28
timotimo ah, partprobe helped. you just gotta give it the devices, too 14:31
hahainternet timotimo: if you are trying to activate partitions of a mapped block device, in general you want kpartx -av and kpartx -dv 14:39
depends on how you've set things up
timotimo i have not heard of that
hahainternet i use it for storing vm disks inside a single lv
without having to bother with anything special
but yeah, it works with anything that has partition tables and can use mapper
timotimo what limitation does partprobe have that this can solve? 14:40
hahainternet partprobe just rescans the scsi bus
kpartx gives access to embedded partitions
well, i guess partprobe rescans all storage buses or whatever, i don't know the specifics
timotimo ah, so with kpartx i wouldn't have had to pass the dev paths
hahainternet i can't say i've done luks on an entire disk before, so i don't know if i can say 14:41
but if you ever have a filesystem in a block device, and want to access a partition
timotimo i'm a bit disappointed by lvm2 here. i had tried zfs before running into a problem and it was a whole lot faster
hahainternet use lvm thin partitioning
timotimo likely because it spread individual files out over multiple disks
hahainternet yes if you set up a zpool
timotimo yeah
hahainternet lvm is just effectively jbod, with thin provisioning now 14:42
zfs is millions of dollars of research, but is owned by a predatory company, so i avoid it :(
timotimo at least zfsonlinux isn't owned by those terrible people
hahainternet it is, Oracle sued in the US to claim ownership of the organisation of an API 14:43
and won
so i would not think open source code makes any real difference
Google only got away through fair use
anyhow just don't tie your company's fortunes to it is all i'm saying :p 14:44
timotimo well, i'm not using it any more anyway, so ...
hahainternet well hope kpartx helps when you come to need it, time for me to enjoy my sunday, what's left of it 14:45
ttyl
timotimo have fun!
my day started waking up far too early, checking on the computer, finding the kernel had bugged inside the nvidia driver and the rsync process had stopped; rebooted into memtest and continued to sleep. then i updated the bios and managed to make my system not boot any more until i removed all pci cards ... 14:46
moritz wow, sounds like a fun start 14:47
timotimo this whole ordeal has been Fun 14:48
in the middle of my first attempt to move all this data over (about 10 terabytes) i ran into an "unrecoverable error" reported by the sata drive (that i had just bought two days earlier) 14:49
hahainternet timotimo: spinning disks? small files?
use dd instead of rsync
for a start, dd recovers better with conv=noerror / ddrescue
timotimo can't. the source device is a few terabytes bigger than the target device 14:50
and many of the files are actually big
hahainternet move the big sequentially stored files
resize the source filesystem
dd it
i mean this is just for performance
timotimo i don't think i'm allowed to do that
hahainternet but once you get to 6 figure numbers of small files
timotimo the source disks ain't mine
hahainternet dding becomes significantly faster
ah, damn that is a huge pain

[Coke] I think I installed it, but it behaves the same as the previous version, so maybe not 21:31

lizmat hmmm... getting an execution error when trying to upload a distribution to CPAN with "mi6 upload" :-( 21:41
500 Internal Server Error, pause.perl.org/pause/authenquery
timotimo oh, that's not happy 21:42
lizmat indeed... but I've verified that my .pause file has the correct credentials
I think I'll check with Andreas to see what's going on
it's not the password, wrong password gives a 401 21:43
timotimo does authenquery do everything, not just signing in?
maybe something's wrong about the file to be uploaded 21:44
lizmat yeah, apparently
timotimo can you make mi6 output what the server has to say to go along with the 500 status code?
lizmat no debug output in CPAN-Uploader-Tiny 21:46
let's see if I can upload the tarball manualy

El_Che I asked to rename the perl devroom at FOSDEM from "Perl Programming Language devroom" to "Perl Programming Languages devroom" 23:16
let's see how it turns out
ckraniak 2 questions 23:45
In Nativecall, how does one pass a CStruct by value?
And how does one pass an array of CStructs (array containing values, not refs/pointers)? 23:46
timotimo for the latter, please see the NativeHelpers modules in the ecosystem 23:47
buggable: eco NativeHelper
buggable timotimo, Found 3 results: NativeHelpers::CBuffer, NativeHelpers::Blob, NativeHelpers::Array. See modules.perl6.org/s/NativeHelper
timotimo i think one of those does what you want
for the former, i'm pretty sure we can't support returning CStruct by value, but i'm not sure about passing CStruct by value.
ckraniak Let me take a look at that module 23:48
ckraniak I tried unioning this struct with a uint32 (correct sizeof) and making an array of those 23:49
timotimo in that case you're in luck; you can just nativecast(YourStruct, @buffer[$index]) i think 23:50
ckraniak And the passing struct by Val I declared the signature to have the struct fields and not the struct itself 23:51
timotimo unioning a uint with a struct is problematic, because "has SomeStruct $.blah" makes it a pointer rather than embedded. but perhaps you can "HAS SomeStruct $.blah" and that could work
ckraniak Yes I used HAS
I think the issue is with the pass by value hack I was trying
Specifically I don't think it packs the same way in a function signature as it does a struct 23:52
It doesn't say it segfaults, but it seems to crash on that line 23:53
timotimo if you have valgrind installed, you can try running your code with perl6-valgrind-m 23:54
ckraniak Isnt valgrind is Unix only? 23:55
timotimo yeah, didn't know you're on windows 23:56
ckraniak Yes, this is WriteConsoleOutput I'm trying to hook 23:57
Lemme check Nativehelpers out 23:58
