Xliff "Configuring and building MoarVM ... 00:06
udobrew/moar-nom/install --make-install"
Well THAT didn't work.
At any rate, if I try and use "--moar-option='--no-optimize'" the outer Configure.pl will still throw in --optimize on the call to MoarVM's Configure.pl 00:07
Which then breaks everything.
00:07 geraud left 00:08 BenGoldberg left
timotimo i don't think --no-optimize exists 00:09
but --optimize=0 definitely does
why are you still using --gen-moar?
i think it'd really be easier to just cd into moar's code and make sure the right --prefix gets set
then you should be golden
00:09 BenGoldberg joined
Xliff timotimo, Well, everytime I've tried doing it from MoarVM, the symbols get erased. 00:10
00:10 pierre_ joined
Xliff So I'm trying to do a complete top-down build to see what I get. 00:10
Call me a masochist. I will probably end up doing exactly as you suggest. 00:11
But I'm.....stubborn.
timotimo you can immediately see if your symbols live after "make install" under moar finishes
with "file", that'll tell you if it's been stripped or not 00:12
oh, btw
there's a tiny bit of C code in rakudo, too
if you end up in there, you'll only see symbols if you made sure that also gets compiled with --debug=something
it'll likely take its CFLAGS and such from moar's config, though
Xliff We'll see. 00:13
And it went fine with "--optimize=0", but right after that the "--optimize" flag gets specified again.
This is using MoarVM's Configure.pl from the top level Configure.pl 00:14
I may just try to rebuild moar after this.

tidy table inputs by removing extra white space and aligning column p…
00:15 skink joined
timotimo clearly --moar-options doesn't have a clue about --optimize 00:16
patches welcome
like "we really need moar to be compiled with optimization, so we add it. good idea, eh?"
hah, yeah 00:17
check tools/lib/NQP/Configure.pm
line 320 is literally
push @opts, "--optimize";
also, nqp has that same file, but both have some differences 00:19
Xliff Yeah.
Also:
gcc -L/home/cbwood/.rakudobrew/moar-nom/install/lib -shared -fPIC -O3 -DNDEBUG -g3 --optimize=0 -Wl,-rpath,/home/cbwood/.rakudobrew/moar-nom/install/lib -Wl,-rpath,/home/cbwood/.rakudobrew/moar-nom/install/share/perl6/site/lib -O3 -DNDEBUG -lm -lpthread -lrt -ldl -o dynext/libperl6_ops_moar.so dynext/perl6_ops.o dynext/container.o -lmoar
timotimo that makes zero sense
Xliff Note that the "--optimize=0" somehow gets passed to CFLAGS and yet the -O3 remains.
00:19 BenGoldberg left
timotimo is that when you have two optimize flags passed to Configure? 00:20
00:20 tardisx left
skink Not to interrupt, but are there any docs yet on that new native string type? 00:20
00:20 branthebuilder joined, tardisx joined
timotimo i wasn't aware of a new native string type 00:21
Xliff timotimo, that resulted from "perl ./Configure.pl --gen-moar --backend=moar --moar-option='--debug=3 --optimize=0'"
00:21 BenGoldberg joined
timotimo oh, i know what's going on 00:21
Xliff So I didn't specify two optimize options.
00:21 pierre_ left
timotimo see how it's called "--moar-option" and not "--moar-options"? 00:21
dalek ar: 4d70f16 | (Steve Mynott)++ | tools/star/release-guide.pod:
doc how-to-get-rakudo
timotimo you're litterally setting the debug to "3 --optimize=0"
Xliff O_O
timotimo and we're not quoting properly
so it should have become -g"3 --optimize=0" in the CFLAGS
Xliff tries again.
00:22 branthebuilder left
Xliff Er. Nope. 00:22
timotimo --moar-options doesn't exist. you have to pass --moar-option twice
Xliff Configure.pl pukes on "--moar-options"
Ooo. OK.
skink timotimo, Second bullet on the release announcement. 'str' instead of 'Str' 00:23
I can't find many references to it though
MadcapJake Xliff: try FILE.path('/dev/stdout') (perhaps on a VM, 1 isn't stdout's file descriptor)
stmuk_ not sure its worth retrospectively changing announcements 00:24
timotimo skink: you mean native string arrays, then?
skink mhm
Xliff MadcapJake, SURE 00:25
timotimo oh, compiler release, not star release?
00:25 kid511 joined
timotimo no, must have been Star 00:25
skink: i literally can't find an announcement that has "str" in it 00:26
as in: in its second bullet
00:26 kid51 left
skink rakudo.org/2016/04/25/announce-raku...e-2016-04/ 00:26
Some of the new compiler features since the last Rakudo Star release include:
Much improved REPL with multi-line support.
Native string arrays.
timotimo yeah, that's not "'str' instead of 'Str'" :) 00:28
that's also not a "new native string type"
MadcapJake Xliff: that's just how I have the class named to match how it's written in C code :P
skink timotimo, Man I just got home and skimmed that :) 00:29
timotimo :)
Xliff is just going to have to suffer with the "-O3" and hopes he can still find the problem. 00:30
00:33 adu left 00:34 leont_ left
timotimo why? 00:36
i told you how to get around that problem
why do you do this to us :P 00:37

timotimo rakudobrew giving people trouble made me look at a carreer in table-flipping 00:39
awwaiid Only the source for rakudo-star-2016.04 is released -- no .msi or .dmg yet eh? 00:47
timotimo FROGGS usually makes the .msi but he seems quite busy at the moment 00:48
awwaiid well I'm psyced and ready to update the purdy "how to get rakudo perl 6" page on rakudo.org :)
stmuk_ awwaiid: I will probably build the .dmg in the next hour or so 00:49

o_O
MadcapJake This is nuts: spin.atomicobject.com/2016/04/26/s...pile-time/ 00:55
timotimo whoops 00:59
huh, so it's about type inference? 01:00
MadcapJake yeah i'm guessing that each added field required checking against all other fields' types 01:01
Xliff MadcapJake, FILE.path('/dev/stdout') worked.

hotel does anyone know where I can set LDFLAGS for moarVM to compile with? 01:27
01:28 geraud joined 01:29 molaf joined
hotel I was digging around the stuff I think makes it build, but I can't be sure 01:30
timotimo if i have to change LDFLAGS, i usually vi Makefile :\ 01:32
hotel so yeah, I saw that the makefile set LDFLAGS=@ldflags@ and I didn't want to change it for fear of screwing stuff up? 01:33
timotimo may i ask what you're up to?
hotel still trying to compile perl6 on WSL 01:34

01:34 tardisx left
hotel it won't compile on the stack 01:35
so I'm trying the ldflags hack
01:36 tardisx joined
Xliff What is the ldflags hack? 01:37
hotel from this site: wiki.gentoo.org/wiki/Hardened/GNU_...quickstart which says to add these: -Wl,-z,noexecstack 01:38
I found the site on a perl6 listserv talking about building on selinux 01:39
Xliff Try adding to the ldmiscflags key on line 274 of moar/nqp/MoarVM/build/setup.pm 01:41
This is NOT recommended, but since I've been digging in the build system tonight. I may as well pass on some of the stuff I've learned. 01:42
skink MadcapJake, reddit comments on that said problem can be resolved if you just add a type annotation
MadcapJake skink: I noticed that in the article comments too :P 01:43
skink Oh, right 01:44
hotel thanks for the help Xliff :)
skink needs to stop simply skimming
hotel I wouldn't be doing this if I wasn't balls deep in trying to game the WSL system lol 01:45
MadcapJake Here's another interesting article: www.evanmiller.org/elixir-ram-and-t...-doom.html
The author makes it sound like "this is so amazing" but really it sounds completely ridiculous, insert an empty string and performance more than doubles! WUT?!

geekosaur something is inappropriately splitting on commas?

tbrowder good morning all: I've noticed the Perl 6 world uses the word 'codepoint' in most places, but many other places on the Net (including Wikipedia and Microsoft) show the word as 'code point'. Any objection to correcting that in Perl 6 (as well as maybe adding it to the doc/STYLEGUIDE.md)? 12:18
timotimo oh, interesting
12:19 domidumont left 12:20 domidumont joined
bazzaar moritz: specifying the port as a string, that works :) 12:20
AlexDaniel tbrowder: I think that codepoint is fine
moritz bazzaar: can you please open a bug at github.com/perl6/DBIish/issues/ for that? 12:21
AlexDaniel tbrowder: it is commonly used, and somebody even bothered to add it to wiktionary as an alternative spelling for “code point”
DrForr unicode.org/glossary/ # It's spelled 'code point' in the Unicode glossary. 12:22
tbrowder AlexDaniel: but our docs are not consistent, so we should pick one or the other and specify it IMHO
moritz then we should prefer the Unicode consortium's writing
bazzaar moritz: yes, I'll give it a go ... also for interest, perl6 reported 'DBDish::Pg::Connection.disconnect is DEPRECATED, please use .dispose' 12:23

AlexDaniel looks at www.google.ee/#q=%22codepoint%22+s...nicode.org 12:24

AlexDaniel DrForr: 25600 results, eh… not all of them are relevant but still
moritz AlexDaniel: curious, on google.com I only get ~6k results 12:26

AlexDaniel hah!

DrForr Different datacenters have different shards? 12:28
_nadim what does a proto like "proto method classify-list(|) { * }" force for type of signature?
AlexDaniel DrForr: sure, but it makes me want to do that through Tor next time :) 12:29
tbrowder the fact that the Unicode group uses 'code point' should be the deciding factor, not popularity--our docs should be technically sound and authoritative as much as possible
12:29 bbkr joined 12:30 perlawhirl left
AlexDaniel tbrowder: I do not agree. Our docs are for people, there's no good enough reason to get it more “technically sound” in this case. Especially when it is such bikeshedding 12:31
12:31 rurban joined
RabidGravy it should be consistent foremost 12:32
12:32 perlawhirl joined 12:33 rurban left
AlexDaniel “code point” – 54 on perl6.org vs “codepoint” – 392 results 12:34
so I'd say that it is easier to change “code point” to “codepoint”…
RabidGravy :)
DrForr Maybe we should also have a glossary in order to encourage people to use the Perl 6-authorized spelling? :) 12:35
AlexDaniel is it “falsy” or “falsey”? 12:36
tbrowder I agree. Perfect uniformity in language is probably impossible, but one mark of good technical documentation is consistent terminology, and a glossary IMHO is a good thing. 12:37
AlexDaniel ok 12:38
there you go: design.perl6.org/S99.html#codepoint
_nadim DrForr: an excellent idea, in all the bigger project, I've been working in, we had a glosary 12:39
tbrowder ...and that's not bikeshedding.
AlexDaniel _nadim: we have two!
RabidGravy wouldn't that glossary be better in the docs
AlexDaniel on is here doc.perl6.org/language/glossary 12:40
and the other one is S99
one*
RabidGravy: yes. lizmat++ did a great job in moving all important stuff from S99 to docs
RabidGravy: feel free to continue it
AlexDaniel really hopes that we will get rid of S99 one day 12:41
perlpilot AlexDaniel: why? 12:44
AlexDaniel perlpilot: have you ever tried reading S99 from top to bottom? :)
perlpilot nope. But I haven't tried reading a dictionary or a thesaurus from front to back either. 12:45
RabidGravy I'd say that the S99 should be restricted to terms that are actually in the design docs
AlexDaniel heh, well S99 is not that long
perlpilot RabidGravy: why? 12:46
RabidGravy because it's a design doc
it shouldn't be in the business of glossarizing things that are just colloquialisms of the Perl 6 community 12:47
AlexDaniel perlpilot: we should not have two glossaries. Right now some stuff is duplicated, so we should probably start removing that from S99…
RabidGravy unless of course it seeks to mandate a particular use of language
_nadim what's $^a? 12:48
AlexDaniel perlpilot: after doing that it will just leave a bunch of words that are not described, so there would be no point to keep it
RabidGravy (and given the authoritarian streak of some geeks I wouldn't be surprised)

synopsebot6 Link: design.perl6.org/S99.html#line_14
perlpilot :-)
[Coke] _nadim: it's a positional so you can use a name for an arg without having to explicitly declare it in the signature.
llfourn_ grondilu: it's NYI I think, in the design docs it says you should be able to push candidates onto a dispatcher which implies to me that runtime proto creation should work. 12:52
[Coke] you'll see $^a and $^b in one-off sort subs, reminiscent of perl5's $a and $b
RabidGravy perlpilot, but that would suggest that really it wants to be in the docs and not the design
it wouldn't need that explanation then
perlpilot RabidGravy: perhaps.
AlexDaniel perlpilot: this was written in 2013 which was before we had proper docs and proper glossary in docs 12:53
perlpilot: also see this github.com/perl6/specs/commit/43de...bc14d4ca5d
_nadim [Coke]: I got that from the example above, thnaks
AlexDaniel which is your commit
_nadim I am trying to wrap my head around Baggy classify-list
grondilu I was building three functions from a common template so I had to do something like my (&f, &g, &h) = map -> &x { sub () { do-something-with-&x } }, &afunc, &anotherone, &yetanotherone. But then I realized that I would lost polymorphism for &f, &g and &h
llfourn_ grondilu: you can do something like my $new_proto = (my proto anon (|) {*}).clone; # But YMV and it might be evil 12:54
RabidGravy y'see I would argue that it should actually be reduced in scope to the first two sentences of the original paragraph, and anything else should go in the docs 12:55
AlexDaniel _nadim: one gotcha is that the order depends on the… uh… codepoint number I guess?
m: sub foo { say $^a; say $^b }; say foo 42, 69

perlpilot AlexDaniel: they are ordered Unicodely 12:56
_nadim seems so
AlexDaniel ah yeah, right
AlexDaniel got confused by his own example
_nadim: in other words, it is probably a bad idea to use readable names 12:57
_nadim lol!
doc.perl6.org/routine/categorize-list would deserve a little work specially explaining the difference with classify and also what a multi level classification/categorization is 12:58

RabidGravy well unless $^aardvark and $^barbarian are natural names for your application
AlexDaniel _nadim: you are right. Please create an issue here: github.com/perl6/doc/issues/new

_nadim multi method classify-list( %test, *@list ) { self.classify-list( { %test{$^a} }, @list ); } This is the example where $^a made me scratch my head. 13:03

grondilu I've found a solution: proto f {*}; proto g {*}; my ($f, $g) = map -> &x {...}, &a, &b; multi f { $f() }; multi g { $g() };
basically storing the result of the map in a hidden storage array.
(or several hidden variables) 13:11

llfourn_ grondilu: it works but it would be nice to be able to just push $f and $g onto the proto

Woodi hi everyone :)
grondilu ^looks like a bug to me
or at least an unhelpful error message. 13:58

mst: are you getting involved with Perl6 now too along with Perl5?
Xliff For modules entered into the ecosystem, is it preferred to use .pm6 and .pl6 instead of the Perl5 equivalents? 15:10
mst zacts: only vaguely, so far 15:11
zacts ah ok, cool 15:12
perlpilot Xliff: I use *.pm6 when I think about it, but often I forget 15:15
(and I've never used .pl or .pl6 because usually my programs don't have some special suffix)
15:15 jjido joined
AlexDaniel tbrowder: I have to go unfortunately, so can't review that right now 15:18
perlpilot (actually ... I did use .pl for a while, but it was with Perl 4 when the .pl suffix stood for "Perl Library" and the .pl file occupied a similar space then as the .pm files do now)
AlexDaniel tbrowder: examples look alright as far as I can see 15:19
geekosaur I use .pl still for programs that are not yet complete
mst Xliff: if you use .pm6, file type guessers (e.g. for synhi) are more likely to get it right
geekosaur removing the .pl suffix means it's reasonably complete
mst Xliff: if you don't use .pm6, you really should 'use v6'
so it depends, do you want to indicate you're perl6 code in your file name or a line of code 15:20

bug for Rakudo that is github.com/rakudo/rakudo/#reporting-bugs 17:28

mst yeah, that's not supposed to happen 17:28
RabidGravy I'd say it was the way that fetchall_* was reimplemented in DBIish 17:29
ZoffixW bazzaar, are both of your Perl 6 installation using the same DBIish version? 17:30
Xliff Is there a difference between ~< and +< (and their siblings)
ZoffixW Xliff, one is for strings the other is for numbers, if I recall. 17:31
RabidGravy massive changes in DBIish since January,
Xliff Thanks, ZoffixW
bazzaar ZoffixW: I reinstated my R* 2016-01 installation, so I think the DBIish versions were different in the two tests 17:32
ZoffixW bazzaar, then it might be the issue coming from DBIish, since it looks like there was a lot changed in it.
RabidGravy they will be
ZoffixW You could clone the repo, checkout an older, working commit and install that (panda --force install .) 17:33
bazzaar ZoffixW: So I should repot as a bug in DBIish instead of Rakudo?
report
RabidGravy I'd say so 17:34
ZoffixW bazzaar, if possible, test it with the same versions of DBIish on both perls. Just update the one on 2016-01 install
That will tell you where the problem lies, even though it's likely with DBIish :)

Lixquid Not as far as I'm aware, I'm just attempting to use the module from the REPL 17:39
(The symbol X was generic, it's actually erroring for me on the symbol "Fast") 17:40
ZoffixW Not sure. I had the same error pre-Christmas, but I forget what was causing it. 17:41
Do you have any BEGIN{} blocks that print anything to STDOUT/STERR?
RabidGravy Lixquid, what is the actual module? 17:42
Lixquid The Discord module, in this case
RabidGravy which uses JSON::Fast via some dependencies
it's a weird problem 17:43
Lixquid panda --installed --verbose shows JSON::Fast as installed on version 0.4 17:44
Is something trying to load multiple versions of JSON::Fast or something? 17:45
RabidGravy say you have some module that uses JSON::Fast and that gets precompiled, then another module uses an explicit and later version of JSON::Fast
Lixquid, I know this because it is actually JSON::Marshal (my module) that creates the problem 17:46
Lixquid Oh, okay, I can see why this is a problem
RabidGravy It has to use v0.4 or better, but JSON::Unmarshal doesn't care which version
and Discord uses both 17:47
it's better now that Panda has the v0.4 JSON::Fast 17:48
Lixquid So, there's two versions of JSON::Fast, JSON::Marshal uses the newer version, Unmarshal uses the older version, and when Discord uses both they collide?
RabidGravy yep
Lixquid Right, ok 17:49
RabidGravy it's probably a bug in the way that precompilation works
Lixquid That kinda sucks :(
is there a way to somehow remove the old version, or force Unmarshal to use the newer version

MadcapJake yeah, I'm working on CURs right now so maybe I can help. Is there some minimum code somewhere that triggers this?
RabidGravy no 18:05
MadcapJake ok :\
RabidGravy I can't think of a way of reproducing in a single piece of code 18:06
MadcapJake not even just `use Discord` in a script?
dalek c: 3a40207 | (Jan-Olof Hendig)++ | doc/Type/Code.pod:
Fixed errors in the usage sections for methods file and line. Also added code example for line.
 18:07
RabidGravy no that won't help either because it may not happen to you
18:08 xfix joined, sno joined
MadcapJake so it's a caused by a specific history of installs/uses 18:08
RabidGravy If you have a module B that depends on module A installed and precomped and a module C that is changed to require a specific version of A or greater and you install the newer version of A 18:09
18:09 tomboy64 left
RabidGravy then using both C and B will give rise to the error 18:09
i.e. B loads the old version and C tries to load the new version
MadcapJake well it *shouldn't* because both versions of A should still be around
RabidGravy or vice versa
exactly 18:10
but *something* doesn't like the two versions being loaded
MadcapJake e.g., A:ver<0.1.0> and A:ver<0.1.1>
RabidGravy well A
18:10 winger_ left
RabidGravy it fails in GLOBAL merge 18:11
18:11 winger_ joined
RabidGravy because that's not versioned 18:11
it's all a bit sucky really 18:13
MadcapJake well if you do ever get that error again (and you too Lixquid) please paste the output somewhere (and use --ll-exception)
ZoffixW RabidGravy, done: github.com/sergot/http-useragent/issues/145 18:14
RabidGravy cheers matey
no way I can test but it probably give me a clue where the problem lies 18:15

RabidGravy though strangely "perl6 -e 'use JSON::Fast:ver(v0.3); use JSON::Fast:ver(v0.4)'" works fine here 18:30

RabidGravy ZoffixW, I did have a comprehensive list of the trait words somewhere, but the calling conventions differ slightly 19:00
so e.g. 19:01
m: multi sub trait_mod:<will> (Variable $v, &foo, :$bar) { say "bar"; foo()}; my $b will bar { say "glarg" }; 19:02
camelia rakudo-moar f7613f: OUTPUT«bar␤glarg␤»
RabidGravy "will" always gets the block there 19:03
timotimo yes, that's what "will" is for
to add a block to a thing
usually we'd install a phaser there
RabidGravy yes
timotimo that's probably why it's different in the grammar
AlexDaniel tbrowder: it is ok! 19:04
ZoffixW Aha. Cool. RabidGravy++
timotimo ah, also: we explain mistery and cry sorrows there because the thing with "is" will immediately be executed
AlexDaniel tbrowder: I still don't understand “where case distinctions do not matter” part though
timotimo but we don't want to execute anything at all if we've stumbled over some problems in the code so far
AlexDaniel tbrowder: it has been there before your changes, but I'd still like to know what it means

RabidGravy sometimes it's a real struggle coming up with things that make sense

AlexDaniel tbrowder: set operators have separate pages 20:33
e.g. doc.perl6.org/routine/%E2%8A%86
tbrowder from my Perl journey so far, I think there are many places that need real examples
AlexDaniel some constants are documented here: doc.perl6.org/language/terms#Identifier_terms 20:34
tbrowder AlexDaniel: then a reference to those pages might be the answer
AlexDaniel tbrowder: yes 20:35
tbrowder I'll see what I can do
AlexDaniel but note that doc.perl6.org/routine/%CF%84 has nothing… which has to be fixed
perhaps you should just duplicate this: doc.perl6.org/routine/tau 20:36
∘ is not documented! 20:37
wu_ can require rename imported symbols? Suppose I have two scripts files, both export a same class name, I want to use as: require "abs_file_one_path.p6" <MyClass> and require "abs_file_two_path.p6<MyClass>; of cause, the second MyClass should be alias to another name?

Xliff Right... now generated .ogg file contains vorbis data but data is still borked from equivalent C code. *sigh* 22:05
timotimo Xliff: you could try to run it under valgrind to see if you're overflowing some buffers or something 22:06
Xliff timotimo++, thanks! I'll keep that in mind.
However the header data was broken by a badly transliterated "last if $ret != 0" when it should have been "last if $ret == 0" 22:07
timotimo if you're on a system that doesn't have valgrind, there's also this "drmemory" thing that also works on windows for example
Xliff So I'm not ruling out logic errors at this point.

Xliff ogg_packet is "class ogg_packet repr('CStruct') {…}"
RabidGravy yeah that should be fine (if the omission of the 'is' above is just an artefact of copying) 22:20
Xliff Well. Taking a break then. I don't know why I get more data rounds out of the P6 code than I do out of the C code. It must be something I'm doing.

grondilu 'Vector @a' means for instance an array of vectors
it's not a vector named @a
you must write 'Vector $a' if you meant a single vector
and you must affect an array to it, not a list
so you need the []
hotel funny that a single vector should be considered a $calar
grondilu makes total sense imho
hotel not mathematically, lol 23:26
grondilu even mathematically.
RabidGravy tum ti tum
grondilu don't assimilate a vector to its coordinates.
hotel iirc, a vector is composed of a scalar magnitude and a direction, no?
grondilu that's one way to sumarize it. But truly a vector is something that can be added to an other vector or multiplied by a scalar. 23:27
