perlawhirl .tell lizmat I'm not sure I'm an authority :D The docs say a Mix is like a Bag, so my opinion is it should behave similar to bags, ie: False. 00:27

Zoffix "we do have something that makes sure dynamic variables from where you called start will stick around for the inside of the start block" 10:40
It's the $*PROMISE dynvar whose $!dynamic_context is set to the context of pre-cue code. Recently-ish (~2017.06) there was a bug where .then wasn't setting it, though I took care for look for all other cases in Promise.pm that failed to set it and I think they all do now. 10:41
And &DYNAMIC looks to see if there's a $*PROMISE dynvar if get getlexdyn fails (and lastly looks in PROCESS::) 10:42
10:44 wamba joined
timotimo but does the dynamic_context of the $*PROMISE not keep the old $*THREAD alive? 10:46
Zoffix I see a $*THREAD made when Thread gets created 10:48
I've not seen the code that shows it not being updated or whatever...
perhaps OP assumed each `start` would have a unique thread.id 10:50
timotimo i wrote some code that prints the $*THREAD.id as well as the $_ for the task created 10:52
and it gave me lots of different thread id -> $_ combinations
Zoffix What's $
?
timotimo just from the for loop i used to create 20 tasks
10:53 mr-foobar left
Zoffix There's only 16 threads, so yeah, the ids would repeat 10:53

Morfent quick question, is does perl6 support freebsd? rakudo and pugs ports have been deleted for years now, and parrot apparently no longer targets perl6 12:49
*does perl6 support freebsd 12:50
Zoffix rakudo is the lastest game in town. Whether it supports freebsd is really a question of whether there's any volunteers willing to ensure that support. I think someone was trying that out not so long ago; unsure what the end result was 12:51
llfourn I'm pretty sure you can build it on fbsd 12:53
Zoffix You could try compiling from sauce: git clone github.com/rakudo/rakudo/ ~/.perl6; cd ~/.perl6; perl Configure.pl --gen-moar --gen-nqp --backends=moar; make; make test; make install;
llfourn (not sure if there's a port though)
Zoffix and adding ~/.perl6/install/bin to PATH and runnign with perl6
12:54 pierre__ joined
Morfent there is no port 12:55
i'll try that though
thanks

perlpilot Morfent: you might want to use rakudobrew if you want something that takes care of the details for you. 12:58
Zoffix *sigh* 12:59
12:59 awwaiid joined, domidumont1 joined
Zoffix You don't want rakudobrew, unless you plan to use multiple versions of rakudo at the same time. 13:00
And it requires doing extra stuff like rehashing after installing binaries that you normally don't need to do 13:01
stmuk_ perl6 worked fine on FreeBSD last time I tried it

nicq20 Comments are considered part of whitespace right? 13:04
llfourn by the compiler? yes.
lizmat fg 13:05
nicq20 Well that explains why my stuff is not working then. 13:07
Morfent i don't think rakudobrew's something i entirely need 13:08
llfourn nicq20: what kind of stuff is that?
13:09 broquaint left
nicq20 I'm trying to emulate the P5 module Smart::Comments. The idea is that comments beginning with >3 '#' will be displayed. 13:09
llfourn ah, for that you'll need to modify the compiler with a slang. Is that what you're doing? 13:10
13:10 broquaint joined
nicq20 llfourn: Yeah, this is what I have so far: github.com/nicqrocks/perl6-smart-comments 13:11
llfourn hmm what you did looks like it should work :\ 13:13
nicq20 llfourn: By calling the regex 'comment:sym<smc>' it gets called, but the QAST returned is never executed. If I call it 'statement_control:sym<smc>' then it never gets called due to the compiler seeing it as whitespace.
llfourn ahhhh
yep that makes sense 13:14
nicq20 Really not sure how to get aroun that. :/
*around
llfourn well...I'm pretty sure there's a $*CURPAD or something variable 13:15
you could append your QAST into it perhaps
though YMMV
nicq20 What is that? 13:16
llfourn it's the current QAST::Block object ie lexical scope
the things that are in it will be executed. Each statement appends to one.
nicq20 What about YMMV?
llfourn your milage may vary 13:17
# YMMV is a thing right?
13:18 colomon joined
moritz it is 13:19
llfourn ah nice. 13:20
13:21 colomon left
nicq20 Are there any docs/examples on how to use it? I can't seem to find it in Rakudo or NQP. 13:24
llfourn definetly not
but you can .push onto it and I think that will work 13:25
maybe if it doesn't try wrapping your QAST in a QAST::Stmts
so $*CURPAD.push(QAST::Op.new(...)) # or whatever 13:26
nicq20 Ah, ok.
llfourn though I've never tried this and it might be a terrible idea
nicq20 Hmm... Looks like it does not have a `.push` method. 13:29
"of type NQPMu"
llfourn $*CURPAD is NQPMu?
nicq20: you might try looking at Actions.nqp 13:31
there are some places where $*CURPAD/QAST::Block are used
nicq20 I am, but there are examples of using `.push` with $*CURPAD.

evanm Hi, I would like to contribute information to the bug tracker, but I can't seem to find a way. 13:46
AlexDaniel huggable: rakudobug
huggable AlexDaniel, Report bugs by emailing to [email@hidden.address]
AlexDaniel evanm: just send an email to this address ↑, that's if you want to file a bug report 13:47
evanm I would like to comment on an existing bug.
AlexDaniel ah-ha, then… there are two options
I think one is to write an email to [email@hidden.address] and include this in your subject: [perl #131722] 13:49
synopsebot6 Link: rt.perl.org/rt3/Public/Bug/Display...?id=131722
AlexDaniel where instead of 131722 you write the actual ticket number
or, you can create a bitcard account, and then you'll be able to write a comment directly on the website
13:49 Cabanossi left
evanm AlexDaniel: Thanks. I have already created a bitcard account, but the "Reply" and "Comment" links don't seem to work. 13:50
AlexDaniel evanm: hmm, what do you see when you click them?
evanm I get a mostly blank page with the message "This service is sponsored and maintained by Best Practical Solutions and runs on Perl.org infrastructure." 13:51

AlexDaniel evanm: can you see anything at all when you're logged in? 13:51
13:52 Cabanossi joined
evanm fwiw the page has no opening <html> tag, <head>, etc 13:52
AlexDaniel evanm: for some reason some newly created accounts are experiencing this bug and we don't know why, yet…
evanm AlexDaniel: I can see the bugs but it says "Welcome anonymous guest" at the top
AlexDaniel ah wait, but then you're not logged in?
click “login as another user”, what happens next? 13:53
evanm AlexDaniel: I appear to be logged in
13:53 nadim joined
evanm AlexDaniel: If I log out, the "About" page includes information about Bitcard 13:53

AlexDaniel: Rather, the gray "Login" box disappears, the yellow box about Bitcard is still there 13:55

AlexDaniel evanm: hm, I think a screenshot would help a lot, but I have a feeling that you're experiencing the bug mentioned above 13:55
although what you see is slightly different… 13:56
evanm AlexDaniel: Oh, I think I figured it out
AlexDaniel: I had a bitcard account but had not finished creating a "Persona" 13:57
nicq20 llfourn: I think it's not working because $*CURPAD does not exist in the comments scope.
13:58 W4RL0RD left 13:59 araraloren left
evanm AlexDaniel: Now when I am logged in I see "My open tickets" (empty) but no way to browse the bugs. 13:59
AlexDaniel: If I enter a specific bug number, I get the message "No permission to display that ticket" 14:00
AlexDaniel evanm: like this? files.progarm.org/2016-02-05-02140..._scrot.png 14:03
evanm AlexDaniel: Yes.
AlexDaniel evanm: okay, *now* we are seeing the bug I was talking about :) 14:04
evanm: just drop an email to [email@hidden.address] saying that your account is broken, and of course include the information about your account 14:05
evanm: oh also
evanm: in your email, say that it is associated with #127461 14:06
synopsebot6 Link: rt.perl.org/rt3/Public/Bug/Display...?id=127461
AlexDaniel (which is the internal ticket ID for the same problem I had a year ago)
evanm: I know it's confusing, sorry for the trouble. 14:07
in fact, I have a feeling that there are more people experiencing this problem, but they probably give up completely and don't even reach this channel… 14:08
so in the end we have only a couple of documented cases, uh…
mst, [Coke]: is there anything we can do about this? ↑ 14:09
that's *at least* the fourth time I see somebody get into this trouble
mst odd 14:11
so this is "newly created bitcard accounts sometimes don't get any permissions" ? 14:12
14:15 nadim left
evanm mst: I also hit an issue where a half-created bitcard account (without a "Persona") led to a buggy experience in the RT... maybe related? 14:16
AlexDaniel: Ok, I sent a message to perlbug-admin about not having permissions
[Coke] AlexDaniel: I can do nothing about it other than refer people to ping the bug admins, as you did. 14:20
14:21 ab6tract left
mst might be worth trying to convince them to consider there's a general bug rather than just fixing stuff one at a time 14:21

evanm Speaking of new user issues, the issue I was going to comment on is #131025. Rakudo Star's p6doc is broken on OSX; it appears to be because the DMG does not ship with any pod files / "doc" directories. 14:33
synopsebot6 Link: rt.perl.org/rt3/Public/Bug/Display...?id=131025
evanm Would be great if the Keeper of the Star could take a look at this issue, as it's a pretty significant usability problem for Mac users 14:34

evanm Hi, is Rakudo's Configure supposed to accept "--with-moar="? INSTALL.txt indicates that it should work, but the script doesn't recognize the option 15:20
stmuk_ evanm: I know what the problem is (not OS X specific) and its now fixed if you upgrade p6doc 15:21
evanm stmuk_: Great, thanks. I worked around the issue by symlinking .perl6/doc to a checkout of perl6/doc 15:22
Zoffix evanm: doesn't look like it: github.com/rakudo/rakudo/blob/nom/...pl#L35-L42 15:23
mst I thought rakudo's configure took maybe --with-nqp ? 15:25
mst needs to go back and see how much of the crazy involved in his cpan dist prototypes is still required
and actually upload the bloody things
Zoffix yeah, but not --with-moar looks like
mst well NQP is tied to the moar so surely it should find the moar from the NQP ?
in theory

Add square versions of "Rakudo Concise" poster

Social-media-friendly format.
nadim Is there a way to read a keypress without echoing it? 15:46
Zoffix yup. Disable the echoing/buffering in your shell.
I forget how. stty or something like that 15:47
ugexe there is also Terminal::Readsecret
nadim Using Terminal::Print (which is a bit buggy so alternatives are welcome) to display a data dump and I'd like to implement scrolling, folding, etc in the terminal
stmuk_ I'm wondering if people might think "Rakudo Concise" was a new distribution 15:49
Zoffix Let them ;) 15:50
nadim ugexe: I don't mind using readsecret but asking people to download and install it is a bit of a deal breaker 15:51
ugexe you could also have your users enter input as morse code and SIGWINCH

geekosaur most systems have a limit to how deeply you can nest #! lines 16:07
on linux that limit is fairly high; on *BSD (including OS X) it's low
so at some point the exec fails and the shell's fallback path interprets it 16:08
stmuk_ still puzzled to why they are seeing it. If anything its more likely under rakudobrew I'd have thought 16:09

evanm Hi, I have a question about wrapping C libraries 18:41
Is there a preferred convention for Enum values? Let's say in C there's something like: 18:42
enum { LXW_CHART_LINE, LXW_CHART_SCATTER }
I'm curious whether I should make the Perl 6 API "enum Chart <line scatter>" or "enum Chart <LXW_CHART_LINE LXW_CHART_SCATTER>" 18:43
(or even <lxw-chart-line lxw-chart-scatter>) 18:44
timotimo yeah that's a good question
i have no good answer to
18:45 pierre__ left
evanm I prefer the first style, but I've hit strange errors if there are name conflicts in the same file 18:46
18:46 zakharyas joined, setty1 joined
evanm e.g. it doesn't seem to like "enum Chart <line scatter>" and "enum Shape <line rectangle>" in the same scope 18:47
geekosaur I think that's expected, yes, since the enum values get exported into the main namespace 18:48
although arguably it should be a warning and then require qualification on names
(currently said qualification is optional, which is why it's an error to reuse names)
18:49 skids joined 18:50 zakame left
evanm geekosaur: it looks like if I put the enums in separate compunits I can effectively require qualifications 18:54

kybr MoarVM panic: Internal error: Unwound entire stack and missed handler :( 23:33
geekosaur you have to handle perl 6 errors including Failures inside your callback; there's nothing to do with them otherwise because C has no clue what they even are 23:35
(note that Nil is a delayed silent 'exception' and Failure is a delayed noisy one) 23:36
23:37 mcmillhj left 23:39 |oLa| left 23:40 dubi0us left 23:42 mcmillhj joined
timotimo yeah, there's nothing in C that moarvm could cooperate with to do stack unwinding and cleanup. the C code you were calling that called you back, it could have done all sorts of things on the stack, like it could assume its stack frame would live a bit longer and pass some pointers to the stack around 23:45
not to mention resources allocated between oyu calling it and it calling you back. that's buffers malloced, sockets created or other kinds of files opened ... 23:46
anyway, bedtime
