samebchase- Hi, I'm using a library in a script which appears to have a bug in version X. I did `zef install "<LIB-NAME>:<ver>:<PREV-VERSION>"`, but the bug is still showing up. How do I ensure, that after `zef install`, the correct library version is picked up. Currently, my workaround was to update the compiler version and then installed the previous version 07:11
of the library so that I start from a blank slate so to speak, and now the bug does not show up.
How do we clean up old library artifacts which might be precompiled and get picked up by the program even though I have installed a different version 07:12

samebchase- gfldex: thanks, I shall do that 👍 09:44
I'm assuming that when a version is not specified, it will pick up the latest version present? 09:45
lizmat well, it's slightly more complicated than that 09:46
you can also specify the :auth<> in a use statement and the :api< >
generally, it will take the best matching and fail if there are none, or there is more than one given the arguments 09:47
09:47 wamba joined
lizmat if you don't specify any at all, I think it will indeed take the highest version one 09:48

lizmat frost-lab o/
frost-lab I want to run a command like "ls -l > 1".
How can I do that in Raku
use the 'run' function 12:31
lizmat raku -e 'run <ls -l>' >1 ??
or do you want the >1 also in raku ? 12:32
frost-lab Yes, I want use pipe to write output to file 12:33
leont my $out = open :w, '1'; run <ls -l>, :$out;
lizmat raku -e 'run <ls -l>, :out(open("1",:w))'

moritz while cleaning out old stuff we just found a big card with congratulations from lots of Perl and Raku (then Perl 6) folks 14:14
the occasion was our wedding roughly 10 years ago
I had forgotten about the card, it brought up fond memories 14:15
sjn that's nice :)
how's life treating you, btw?
moritz the signatures I can read are from lizmat, wendy, sorear, TimToady, jnthn, Peter Rabbit Rabbitson, theorbtwo, Markov, szabgab, Schwern (page 1) 14:17

moritz sjn: as good as can be during a pandemic, I'd say. Lots of small annoyances like broken appliances and such this year, but we're healthy, I have we well-paying and secure job that allows 100% remote work, and we're all healthy 14:19
sjn nice :) 14:20
moritz kids are thriving, and my baking and cooking skills are improving :-)
sjn: how about yourself?
sjn moritz: I'm doing ok. Working for a startup now (Mojo/etc) that's doing pretty well. Pandemic is much less horrible here than in most of Europe, and I'm managing to keep myself busy :) 14:22

we had planned for our younger daughter to attend the 17. May celebrations in Oslo this year, but that didn't work, of course 14:31
the real bummer is that starting from September this year she is in school, and that's not during any Germany holidays, so getting her there in future will be much harder/more hassle

ben_ Can anyone think of a way to create a recursive class using `anon`? For example `class type { has type $!inner }` compiles but `my $type = anon class { has $type $!inner }` does not. 16:25
tobs ben_: you can refer to the class being currently defined through ::?CLASS 16:31
m: my $type = anon class { has ::?CLASS $.inner }; say $type; say $type.new.inner.WHAT 16:32

jmerelo UukGoblin: looks like the absence of a blank line after a comment wreaks havoc there. 18:07
ben_ Are there any JS or wasm linters that have support for raku? 18:08
jmerelo ben_: well, we use one for the docs. It's not perfect, but it works pretty well. It's based on the Atom mode for Raku. 18:12
ben_ In the docs repo? github.com/Raku/doc 18:17

ToddAndMargo Hi All. I am having trouble finding the command to create a new blank file. 19:36
moritz touch yourfile 19:37
ToddAndMargo `touch` is system command. I am not finding it in the raku docs. I suppose I could `qqx ( touch yourfile )`. I would like to be able to do it from Raku. 19:39
19:45 perryprog left
thundergnat "yourfile".IO.open(:w) 19:45
19:45 perryprog joined
thundergnat That will overwrite an existing file though 19:46
"yourfile".IO.open(:a) # will create if it doesn't exist, but not wipe out an existing file 19:47
ToddAndMargo Works for me. That way I do not have to do an unlink. Thank you! 19:48
Grinnz metacpan.org/release/Path-Tiny/sou...L2008-2024 is how to approximate touch in perl, so from raku would be a similar process (utime is a function that sets modification time)
ToddAndMargo :-) 19:50

lizmat wonder if it would make sense to allow spurt to have "" for a default content of file, to easily allow creation of an empty file 20:10

ToddAndMargo what is the syntax to run and release a program? `start` does ot error out, but he program does not start. 20:33
ot = not
ben_ Are you looking for `run` or `shell` maybe? 20:35
ToddAndMargo I don't care which, just the result that the program I run gets released and my program continues on its way 20:39
I like run, but it waits for a return.
Zero_Dogg Proc::Async maybe? 20:42
ToddAndMargo how would I use that?
Zero_Dogg docs.raku.org/type/Proc::Async 20:43
lizmat rdocs.raku.org/type/Proc#method_spawn perhaps ?
ToddAndMargo that seems to be for writing to files, not running programs. Am I missing something? 20:45
Zero_Dogg Both Proc.spawn and Proc::Async are for running subprocesses 20:47
ToddAndMargo would you mind writing me an example of spawn? 20:50
Zero_Dogg Proc::Async lets you run them in a non-blocking way
I'm not sure what lizmat referred to with Spawn to be honest. If you're looking to run a command synchronously you're probably looking for 'run', to run something asynchroniously Proc::Async 20:55
m: run "pwd" 20:56
camelia /home/camelia
Zero_Dogg whereas with Proc::Async: 20:58
m: my $pA = Proc::Async.new("pwd"); my $promise = $pA.start; await $promise
camelia /home/camelia
Zero_Dogg You can drop await-ing the promise to just go about your business 20:59
ToddAndMargo p6 'my $pA = Proc::Async.new( "/usr/bin/leafpad" ); my $promise = $pA.start;'JOy! 21:06

Hermitude is there any effort underway to making raku into the kind of scripting language runtime that can be embedded in a c/c++ program? 22:54
For example, as an extension mechanism for said program?
sjn Hermitude: out of curiosity; why would you want to do something like that? (serious question - I've seen plenty of people ask for this, and actually use this, but I've always thought there was something backwards about this) 23:02
I have to admit I probably am just unaware of any situations where this is the best pattern... 23:04

cpan-raku New module released to CPAN! Getopt::Long (0.2.0) by 03LEONT 23:19
Hermitude I'd like to build a desktop app with plugin/extension capability offered via raku
i LOVE the language but unfortunately it doesn't seem to offer a direct means of embedding rakudo and moarvm 23:20
MasterDuke i can be done, look at Inline::Perl6
*it can 23:21
Tirifto leont: Thanks! :)
leont Tirifto: for Getopt::Long? :-) 23:22
MasterDuke metacpan.org/pod/Inline::Perl6
leont has a lot of things to say about this, but ENEEDTOSLEEP
Hermitude i will take a look 23:23
I think I've heard of it before and it seems to be a one-off rather than a well-trodden path
Tirifto leont: Yeah! I just made use of it yesterday. (And today, technically.)
leont has been planning to write a "why everyone should be using Getopt::Long" article, but haven't gotten around to it 23:24
Tirifto I guess you should sleep first, but I’ll be looking forward to it! 23:25
MasterDuke i suspect that's a reasonably fair assessment. it's probably a bit late now, but if you have questions nine (who wrote it and Inline::Perl5) is usually around during the day
leont The hard part of embedding is not calling functions from A to B, but dealing with data 23:26
Hermitude Also since it's calling rakudo with no binary modifications it is likely spawning a child process
MasterDuke pretty sure it's using libmoar.so
leont Yeah, it's a bit esoteric still, but entirely possible 23:27
Hermitude Sure, you have to offer conversions and wrapping -- but this is the purpose of engineering native support directly into the project
Man I would really get a lot of use out of an embeddable Raku interpreter
MasterDuke but my knowledge is all second-hand at best, nine can actually answer any questions 23:28
Hermitude Right now Python is the default go-to extension mechanism and tbh it just sucks -- no native multithreading is too big a strike
leont at some point completely programmed themselves into a corner writing a libperl++, he's not wondering what a libraku++ would look like
Hermitude there's also Lua but I don't like it either 23:30
leont Lua is optimized well for embeddability, but it's not the greatest of languages 23:31
It's great for what it is designed to do, but not so great otherwise, IMHO
