sena_kun ufobat, do you have latest version of complete one? 08:20
ufobat, you need to either create raku SDK and set it for the whole project or if you are using latest complete, there is another nice way to have raku SDK added in this release. 08:21
ufobat what is "complete"? the not-plugin-version? 08:22
sena_kun ufobat, complete == not community, the one with paid subscription. It provides both plugin and non-plugin version with more features, has shorter release cycle and other goodies. 08:23
ufobat ah! no I do have the community version
sena_kun Global SDK then. Or in a month we will do a new community release with another way on board. 08:24

sena_kun ufobat, hmm, so setting project SDK to be raku one works or? 08:49
ufobat it works on comma ide, it does not wor on idea with the comma plugin,
08:49 soursBot left
ufobat (I've deleted the .idea folder and imported in again, but it stays broken) 08:50
08:51 rindolf joined
sena_kun ufobat, did not work in what way? 08:51
ufobat i could apply the settings, so the raku sdk is attacht to that project. but the syntax errors are still found. those for `done-testing` and stuff 08:52
sena_kun oh 08:54
ufobat, is it persistent after restart?
ufobat yeah, it is persistent
sena_kun sigh 08:55
No luck then. Previous release did improve some parts in this area and I hope to address more platform-specific issues in next one. They are the most complex to resolve and usually the most annoying when you have resources shortage. 08:57
ufobat on comma i can not install other plugins, is that intentional?
08:57 jmcgnh joined
sena_kun ufobat, not really, that's an old bug fixed about two releases ago. 08:58
08:58 andrzejku joined
ufobat i've got comma 2020.04 08:59
sena_kun This one doesn't ship the fix, I'm afraid. 09:00
ufobat a different topic: i couldn't find which version of idea is supported for the comma-plugin, because it does not work on the latest idea
09:01 sarna joined
ufobat but comma 2020.04 is the latest one to download on the website :( 09:01
09:02 MasterDuke joined
sena_kun ufobat, 2019.3 works with it. 2020.3 is supported since 2020.05. 09:02
ufobat i've idea 2020.1.2 which does not work with the plugin 09:03
sena_kun Yes, latest community Comma plugin works with idea 2019.3. 09:04
ufobat except for me :( well i guess i need to wait for the next comma release so I could either use comma and install my own plugins, or i could use comma on a different ide, where the SDK works 09:07
s/ide/idea version/ 09:09
sena_kun ufobat, can you install your plugins from filesystem?
ufobat yeah i guess that might work :) 09:10
09:10 noisome_possum joined
sena_kun The bug is related to plugin market, but the plugin stallation should work given they are compatible with 193 build (that is, 2019.3 IDEA version. 09:11

Zero_Dogg Hi! I've been using Raku for a small command-line app that I've been hacking on, and I'm noticing that it's quite slow to start. A simple '--version' which just outputs the version number takes 3 seconds. Are there any specific features of the language that are really slow to compile in the current implementation? (rakudo/moarvm) 09:42
ufobat you can have you code in a module, because modules get precompiled 09:47
this should increase the startup speed a lot 09:48
if you need an example: modules.raku.org/dist/cro:cpan:JNT...ls/CLI.pm6 09:49
09:50 antoniogamiz left
samebchase- ab5tract: Nice post!! 09:50
Zero_Dogg thanks, that might be a good idea, since the overhead is quite a lot for a cli-app. Is there some sort of generally-agreed-upon magic for a script to locate its own lib dir? Ie. I'd like to support someone just cloning the repo, andsymlinking the executeable script into ~/bin 09:52
(ie. FindBin+use lib "$FindBin::RealBin …" used to be a way to do it in perl) 09:55
sena_kun Zero_Dogg, we don't do it this way here. You can provide a distribution of your app with code in `lib` and `bin`. The zef package manager on `zef install A::Cool::App` will install lib and bin in a way which would work for the user. 09:57
I mean, you create a normal "module" (which is called distribution) here with your code, tests, docs, resources and maybe runner scripts in `bin`. Then it can be managed using zef for the end-user. 09:58
10:01 JJMerelo left, Altai-man_ joined 10:04 sena_kun left
Zero_Dogg sena_kun: Yep, I realize that, but that breaks the expectation of clone repo->run. I can appreciate it being cleaner, but for simply trying out something, having to resort to yet another package manger probably isn't worth it. 10:06
tellable6 Zero_Dogg, I'll pass your message to sena_kun
10:07 wamba left
Altai-man_ Zero_Dogg, I am not sure what is your goal. Do you want it to be handy for developers of the module or for users? 10:08
Zero_Dogg Altai-man_: It's not a module. It's a command-line application, so intended for home end-users. It just happens to be written in Raku. 10:09
10:09 rindolf left 10:10 rbt left
Zero_Dogg Right now, it's just a single file, around 2300 lines including comments and docs. But it's painfully slow to start up. So the recommendation was to split parts of it into a module that the script just loads, to get precompilation. But I'd rather not require users to fiddle with zef unless they have to. 10:11
10:11 rbt joined
Altai-man_ Zero_Dogg, well, technically you can go with `use lib $?FILE.IO.parent.child('lib')` or something like this. It takes compile-time path to the script executed in $?FILE, then gets lib directory path and adds this path into a path to search modules for. 10:12
s/into a path/into paths/ 10:13
Zero_Dogg Altai-man_: I'll look into that, thanks. Will raku still precompile the libs though, or is that something that zyf does on install-time?
Altai-man_ Zero_Dogg, it will still precompile them.
Zero_Dogg Altai-man_: Right then. Thanks! 10:14
I'm not opposed to releasing a distribution of it at all, that might even be a preferred way to install it, I just don't want to break existing expectations of clone->run
lizmat Zero_Dogg: you should realize that zef is a frontend to module installation logic that is in the core 10:17
Zero_Dogg lizmat: right, but pretty much the de-facto one at this point, isn't it 10:19
lizmat yes

Zero_Dogg Is .pm6 still the recommended module extension, or is it being phased out for something more raku-ish? 10:37

ufobat is there anything i need to do beside set a breakpoint and run a script in the debugger in comma, in order to stop at this breakpoint? 11:37
Altai-man_ ufobat, not really. But current MoarVM support of breakpoints is LTA, so you might have troubles with 1)breakpoints being hit more than once; 2)breakpoints not being hit. The second case is resolved by simply adding some, dunno, say statement around the place you want to look at and add a couple more breakpoints on them. 11:44
11:45 finanalyst joined
ufobat none of my breakpoints get hit :-( 11:46
Altai-man_ ufobat, I wish we had more moarvm-level hackers with time on hands... The workaround I wrote above usually helps. 11:47
11:47 pheix joined
ufobat I've added a couple of says and added a breakpoint on each. unfortunatelly it didnt help. 11:49
pheix Hi, friends! Just noticied that download link for Star Bundle 20.01 sources (linux&mac) is returning 404 (((( rakudo.org/latest/star/src 11:50
Altai-man_ ufobat, you might want to add more... 11:51
ufobat like 10? 11:52
Altai-man_ ufobat, 6-8? 11:53
If you have 10 and it doesn't work, then, erm, I assume you are running it in debug mode. As in, not `Run script foo`, but `Debug script foo` in Run menu.
ufobat i had 7, let me add 4 more.. 11:54
antoniogamiz Test::Output has been deleted?!
ufobat yeah I pushed "debug script"
nope :( 11:55
doesn't work
Altai-man_ No luck then, sorry.
antoniogamiz ignore my last message, my zef installation is not finding modules for some reason
11:56 rindolf joined
Zero_Dogg Do I need to define a 'unit' within a rakumod-file (like perl5 'package')? Ie. if I've got a single class in lib/Foo/base.rakumod declared with 'class fooBase is export', do I need a unit declaring 'unit Foo::base;' as well? 11:57
11:57 dolmen joined
antoniogamiz Zero_Dogg: or 'class diaso {}' or 'unit class diaso;' 11:58
Zero_Dogg antoniogamiz: What I'm unclear about is what is implicit here. I want a base class that I load with 'use Foo::base'; If I just declare 'unit class Foo::base'; in that file, will said class be exported as "Foo::base" upon 'use Foo::base'? 12:01
12:02 sena_kun joined
antoniogamiz yep 12:02
Zero_Dogg Thanks, I wasn't quite sure from reading the docs 12:03

fluca1978 hi, given an array of integers like (1,1,2,3) I would like a smart test to see if a number appears more than once. So far I've found only: `for @digits -> $number { $ok = False if @digits.grep( $number ).elems > 1; } Any suggestion? 12:20

Expand on the use of {*} with proto

The documentation was not as clear as I needed. I tried several times to understand it, but failed. I got it nearly right when I asked on perl6-users. Crucially '{*}' is a special token without whitespace - this needs to be noted. The extra example combines the proto declaration with methods that use it.

oddp Thank you, liz! 21:23
Grinnz that list of tweets is pretty good evidence for why i suggested not to use 7... but i think the prior art of php 7 and such help with the messaging at least :/ 21:25
lizmat fwiw, I also suggested to not use 7 to Sawyer 21:29

El_Che what's done is done :) 21:30
lizmat is my impression wrong that Perl 7 is not a done deal yet, at least not wrt p5p ? 21:31
Grinnz that's kind of the discussion itself right now :P
21:31 Box joined
El_Che I don't think they can backtrack now 21:31
the discussions it's probably about what perl 7 means 21:32
Grinnz while i want and hope that perl 7 means something different, yeah, i don't see the overall major version usage changing
El_Che Grinnz: what do you mean? everyone will stick with 5? 21:33
Grinnz er
21:33 melezhik joined
Grinnz sorry let me reword that... i don't see the direction of releasing a "perl 7" changing 21:33

I want to annotate enum entries, however it doesn't look like I can POD-After document each enum entry. How difficult would it be to add that?
Is this something that can be done in module space?
I suspect I might need a Slang to get that to work. 23:57
