eno can anyone help me with an error I'm getting while trying to install a compiled version of perl6 01:30
this is the error:
perl6-m tools/build/install-core-dist.p6 /gnu/store/qp5w8m517cfbi5lc30g8127ss92d2ycs-rakudo-2018.12/share/perl6/No writeable path found, /gnu/store/qp5w8m517cfbi5lc30g8127ss92d2ycs-rakudo-2018.12/share/perl6 not writeable in block <unit> at tools/build/install-core-dist.p6 line 28
and here is what is in install-core-dist.p6
$*REPO.install( Distribution::Hash.new( { name => "CORE", auth => "perl", ver => $*PERL.version.Str, provides => %provides, }, prefix => $*CWD, ), :force,); 01:31
01:31 zacts left
eno for some reason $*REPO.install says the dir is not writable when it is running as root 01:32
btw, this is coming from the Makefile in the rakudo repo
line 641 01:33
Xliff eno: Can you check the permissions on those directories? 01:34
Worst comes to worse, you can make them world-writable and see if that fixes the error. 01:35
Home is there any way to run perl6 on windows 10 and get the libraries that need gmake, like cro?
eno ls -la /gnu/store/qp5w8m517cfbi5lc30g8127ss92d2ycs-rakudo-2018.12/share/total 16drwxr-xr-x 4 guixbuilder1 guixbuild 4096 Jan 17 18:13 .drwxr-xr-x 4 guixbuilder1 guixbuild 4096 Jan 17 18:13 ..drwxr-xr-x 3 guixbuilder1 guixbuild 4096 Jan 17 18:13 nqpdrwxr-xr-x 12 guixbuilder1 guixbuild 4096 Jan 17 18:13 perl6 01:36
thats messy
drwxr-xr-x 12 guixbuilder1 guixbuild 4096 Jan 17 18:13 perl6
guixbuilder is running the build 01:37
all the other perl install commands work except for the $*REPO.install
I'm not that familiar with the perl6 module system so I'm kinda stuck 01:38
"Worst comes to worse, you can make them world-writable and see if that fixes the error." this is an automated build script so it's hard to make changes in the middle of the make install process 01:40
does anybody know how $*REPO.install works and the types of permissions it needs? The Makefile shouldn't be failing 01:48
even if i run the command manually as root it still gives me a permission error 01:49

ufobat anyone intersted in maintaining github.com/zoffixznet/perl6-Temp-Path ? 10:17
;)
robertle I actively use it, so I could look after it as well 10:19
ufobat i've having directories that dont get lost 10:20
and i think that is because of the issue number 4
is there something you need to be aware of when you use Channels in combiation with END phasers? 10:21
Some exceptions were thrown in END blocks:
X::Channel::SendOnClosed+{X::Await::Died}: Cannot send a message on a closed channel
jmerelo clickbaits github.com/perl6/doc/issues/2575 for some brainstorming on documentation organization. 10:22
ufobat i love the pink/black tags on it, jmerelo :D 10:28
jmerelo ufobat: let's see if they draw everyone's attention... 10:29
ufobat *crosses fingers*
jmerelo ufobat: I've also used the new "pinning" thing in GitHub to pin this one: github.com/perl6/doc/issues/2542 10:31
timotimo you have to be aware that an END block gets registered immediately when the parser finds it
so it'll be run even if the scope it's in was never actually called

jmerelo ufobat: if you are still in your module fixing and creating frenzy, could you take a look at this? github.com/perl6-community-modules/uri 10:36
ufobat am i? i am not like mohammad anwar :) 10:38
hkdtam sorry for bothering guys, should any shift result of uint32 also within uint32? 10:40
jmerelo ufobat: Manwar thing is permanent, yours seems to be time-constrained.
ufobat: anyway, you seem to have some issues (literally) there, and it's a community maintained module. That means us. 10:41
ufobat and he is the more skilled guy :-)
i am wondering that's going wrong there, the grammar is not matching
youre talking about your issue that you've craeted there recently, jmerelo?
is it a "released" version or is it HEAD? 10:42
jmerelo ufobat: well, that's one
jnthn hkdtam: Calculations are done at full width, the size is about the storage
jmerelo ufobat: but there are issues dating back to 2015
ufobat the hacktoberfest issues, yeah :) 10:43
hkdtam jnthn: oh thx a lot 10:44
jmerelo ufobat: anyway, if you've got the time, please take a look. I'll keep it in my own backlog (which includes lots of pink-and-black labeled issues in /doc) anyway 10:45
ufobat I'll write it down on my list as well. So far i just send PR to stuff that i was using and didnt work as i wanted it. 10:46
jmerelo ufobat: this URI thing is pretty down the food chain in the ecosystem. It's bound to come up sooner or later. The doc builds, since they happen several times a day, are kind of a canary for the modules it's using, because it's also using HEAD in Rakudo. 10:49
ufobat your issue is just with HEAD? 10:51
timotimo DBDish::SQLite: Error: not an error (17)
what fun!
jmerelo ufobat: not sure. Might be. 10:52
ufobat: it's not been failing so far, so it's likely it is. 10:53
ufobat i dont know (yet) how to have multiple perl6 installations on windows
any advice?
jmerelo ufobat: rakudobrew does not work? Or p6env? 10:54
ufobat: I mean, about HEAD, yep, that issue is with HEAD, since that's the binary we use, but the error that produces it need not have been introduced in the last commit.
ufobat i am not sure, i think rakudobrew does not work because the PATHs need to be fixed in the configuration gui of windows, no?
i wasn't aware of p6env 10:55
jmerelo ufobat: No idea. I've been Windows-free since circa 2003.
ufobat likewise :-)

$ prove6 --version does return 0.0.6 for me 12:24
the current version should return 0.0.3, and thats the case for 1 year now
moritz it seems that you have a new version installed than was released? 12:25
ufobat i did install it with zef! 12:27
there is a TAP.0.0.6 in my .zef/ directory
0.0.6 is released on cpan
moritz then why do you say it should return 0.0.3? 12:28
ufobat becase it is either not leont's module or it is on cpan by accident
github.com/perl6/tap-harness6/blob...prove6#L67 <- that file has not been modified since 1 year 12:29
the current version of the module is 0.0.4
zef search TAP::Harness shows 0.0.6 on cpan
and the cpan version (0.0.6) does "test" a file named t/whatever.txt instead of only *.t files 12:30
thats the reason why perl6-community-modules/uri fails
it "tests" this github.com/perl6-community-modules...pected.txt
modules.perl6.org/dist/TAP:cpan:LEONT <- thats the 0.0.6 12:32
moritz but that's TAP, not TAP::Harness 12:33
ufobat but if you click on the github-repo button you're on tap-harness6. 12:35
it's the same code, it's just in a different state 12:36
moritz ah, confusing :/ 12:37
ufobat and there is the bug that jjmerelo was getting on uri -> modules.perl6.org/dist/TAP:cpan:LE...prove6#L11

kudzo Hello perl community. so I found github thread where github.com/perl6/user-experience/issues/33 14:55
perl community became too toxic with all this sjw shit. 14:57
my question now is If you need to move from perl to another language what whould U choose?
El_Che kudzo: yes, please do 14:58
kudzo: choose whatever you like
kudzo most priorities are fast-development, containerable 14:59
jnthn Choose a language with as few users as possible. Then you won't have any community to worry about. :)
eseyman I don't know of any language that has avoided "all this sjw shit" 15:00
huf sumerian?
eseyman plus that specific issue has more or less resolved itself 15:01
so there is nothing to complain about
kudzo: give perl6 a try :-)
kudzo eseyman, yes but we lost good man because of this issue. And perl6 has chance to become dead faster than become popular. 15:02
15:02 kurahaupo left, kurahaupo joined
pmurias kudzo: how was the renaming drama sjw related? 15:03
15:03 p6bannerbot sets mode: +v kurahaupo
El_Che kudzo: I would try Java if I was you. Oracle is still evil, so no chance of whatever Illuminati plot or whatever 15:04
kudzo El_Che, yes. I looking forward kotlin nice lang and U can express your self easily like in perl. 15:05
eseyman pmurias: from experience, sjw doesn't mean anything anymore
El_Che See you have world of choices, and if they ever get women programmers in that language, you can move on
tyil El_Che: "sjw bullshit" and "women programmers" existing are two entirely different subjects 15:06
you're not helping anyone by acting like those are the same thing 15:07
El_Che people that use sjw are stupid in my book, same page as people that feel uneasy with women or gay people
so, whenever I see SJW used in a sentences my bullshit alarm goes on
tyil so you have to limit your way of thinking too, and make silly arguments that are in no way beneficial? 15:08
15:08 sena_kun left
El_Che getting read of people that are stupid enough to use the term SJW? A great day 15:08
rid
tyil people who dislike the "sjw culture" are in no way related to people who feel uneasy with women or gay people 15:09
El_Che "sjw culture"
lol
jnthn This isn't on-topic here.
tyil jnthn: good point
this isn't going anywhere anyway
El_Che nope
someone wants to leave because of SJW? sure, go ahead
my 2c
kudzo El_Che, sorry that I triggered U(; 15:10
El_Che, The main reason I want to leave language because I dont feel its safe for bussines. 15:11
El_Che Zoffix leaving has nothing to do with SJW
kudzo El_Che, but because of what? can u explain please ? 15:12
tyil kudzo: Zoffix left because he no longer had fun working on Perl 6, "I think I need to take a long look at my life and re-evaluate what is in it that actually makes me happy." 15:13
El_Che kudzo: I don't want to reopen the discussion (most of it can be read on the channels logs), but I'll just say there is nothing that can be labelled as SJW (despite on how stupid that label is). 15:14
tyil I do think this could've been avoided, but it already happened, and I'm not a great mediator in any case anyway :'D
El_Che for the record, I sympathized and voiced my support for Zoffix's efforts (e.g. the renaming/alias thing)
and with that, I'll refrain from comments 15:15
pmurias kudzo: the github thread was caused by drama in regards to aliasing/renaming Perl 6 to Raku and not as as far as I know any SJW activity
kudzo ok why ribasushi left community? 15:16
El_Che ribasushi was never in the Perl 6 community (that I know of)
he's mostly focused on Perl 5 15:17
kudzo I just think perl5 and 6 communities are almost all the same people
El_Che No, it's not the case
tyil there's overlap, but they're not all the same
El_Che Zoffix was only part of perl 6 the last years, riba only of perl 5 15:18
tyil conversely, there's also a subset that hates the other with a passion
15:18 w17t left
El_Che also, in the case of ribasushi, it's wasn't anything "SJW", he's concerned about perl5 and p5p. He's on the channel, so you can check with him :) 15:19
masak kudzo: you seem to have fallen in with the wrong kind of people, based on your usage of both "sjw" and "trigger" in the past brief exchanges. 15:20
kudzo: out of curiosity, does it make sense to you to describe "social justice warrior" as a derogatory term?
do you feel there's too much of a focus on social justice nowadays? :) 15:21
pmurias please don't make sjw support an official stance of the channel :(
El_Che We have people here from different backgrounds (including gay and trans people) and they need to be treated with respect like everyone else. There is nothing SJW about that. If that's an issue, I think we're missing common ground here.
tyil pmurias++
kudzo as for ribasushi I read this twitter.com/ribasushi/status/945637302402998273
El_Che there is no abuse on this channel and no people policing everyone words. So, using SJW in this context is really investing problems that we luckily don't have 15:23
eseyman inappropriate language, fact-free and insulting; yup, that's by ribasushi
kudzo El_Che, thanks for explanations. I like to take information from first hands not from gossip 15:24
El_Che contact Zoffix if you feel you need more details
and again ribasushi's conflict is pretty centered on p5p 15:25
b2gills I think this conversation is running afoul of the culture we want to have: raw.githubusercontent.com/perl6/sp...draft.pod6
masak the founding member of this channel is transgender, and has transitioned. I always admired how this community embraces people of different backgrounds.
tyil I had too, until they started censoring talks at the conference 15:26
kudzo El_Che, but all this shit happening in both communities past years makes our company very nervous. We considered to move to perl6 from p5 before january.
tyil there's a difference between being respectful to people, and trying to constantly play a victim and have the world change to your wishes 15:27
masak b2gills: as much as I don't disagree with anything in particular in that document, I no longer believe "be reasonable" (its thesis) is enough as a community guideline.
tyil the first is being a decent human being, the second is being an sjw
b2gills The person who was "censored" agreed that they shouldn't have said the things they said.
kudzo tyil, ++
tyil convincing the person of some insane ideology doesn't mean that ideology is correct now, b2gills
El_Che kudzo: I don't know what you're referring to. Communities and not project direction? 15:28
eseyman kudzo: these things happen in all programming communities (and I could remove the word programming here)
tyil it's also very hard to judge anyway, since nobody is willing to give *any* details on what actually happened
or what was said that was inappropriate, or how many people complained
El_Che Besides the naming discussion that returns every six months, I haven't seen much drama inside the perl 6 community
tyil I do agree with El_Che, the Perl 6 community seems remarkably stable and friendly 15:29
15:29 curan left, pmurias left
tyil but I do hope we can keep it this way, and last year's TPC really made me doubt that for the first time 15:29

El_Che tyil: my last one was 2016, I missed the episode you're referring to 15:30
b2gills tyil: So then as far as you know it could have been the most hateful words to ever come out of anyone's mouth. My guess is the person said something that they didn't realize could be hurtful, and once they found that out they didn't want to be associated with those words anymore. 15:32
pmurias masak: I'm all for embarcing everyone in the community (regardless of their background or whatever horrible right wing or left wings view they hold privately as I don't see how that's relevant towards writing Perl 6 code), I just don't want to have an official ideology
tyil I don't think this channel is the place for that discussion, b2gills
so I'm not going to respond to it 15:33

kudzo Ok! Sorry ppl for disturbing you on all by this questions(: I just needed to fix the information that I got from gossips.
El_Che kudzo: the discussion is no problem, but be careful with the approach (like I demonstrated, SJW labels are not appreciated). 15:45
kudzo El_Che, ty (;
El_Che I would have been less sarcastic if I'd known your reasons were not meant as trolling 15:46
kudzo pmurias, python is one of the candidates but not preferable.
El_Che so excuses for that
kudzo As for perl6 I think we will give it a try
we all here are perl5 fans so perl6 is our candidate n1 15:47
El_Che, I am from generation that born inside trolling communities. And good sarcasm sometimes can explain much more better than trying to be polite. So nevermind (; 15:49
