leont It not working was my own bug, but not being able to dd that regex made that hard to discover 00:02
moon-child that's fair. It would be nice if dd could actually deconstruct that regex 00:03

warriors hi, what need to be done to add a discourse forum to the raku community, while i think the community is small and the forum will not be super active, i still think its a nice resource and place to ask questions, and keep history of questions and answer 17:46
I asked in few other forums how they did it, and they all payed for the hosted option as 50% discount
www.discourse.org/pricing
If we go for the standard plan, which i think will fit the size of the raku community its only 50$ per month
do you guys think this can be funded
rust, fsharp, julia, ocaml, go ... all have a discourse forum 17:47
and i find it really helpful 17:48
17:54 sjm_uk joined
Xliff warriors: $100/month is super pricey. 17:54
warriors for foss, we will pay only 50
Xliff warriors: OK. Getting better.
warriors we can always install on our own server 17:55
Xliff lizmat: What kind of traffic does the Weekly pull in?
warriors but i think the admin cost outweight 50 per month
Xliff I would pay that for a couple of months.. that's assuming the traffic is there.
warriors well if we open the forum for also perl5/7 17:56
the traffic will be there
i think
Xliff Perl doesn't have a discourse, either?
warriors but anyway, beside the price and traffic, i think a forum is nice, currently i ask here, but obviously this missing search, or on the facebook page 17:57
and the facebook page is not fun
if perl had a discourse, we should use it for raku too
perl and raku are still same familly of languages
Xliff I agree. That's up to the their community, though.
Yep. If only more ppl understood that.
warriors and if the raku community fund a discourse forum i think it would be nice to open it for perl5/7 17:58
Xliff warriors: If you are serious about this, write a call for discussion, here:
warriors what is that
Xliff github.com/Raku/problem-solving
It's a better place for this type of discussion.
warriors ok, will open an issue there, i will collect some information first 17:59

Xliff How can I load a core file in rakudo-gdb-m? 20:47
SmokeMachine Is there anyway of doing this? www.irccloud.com/pastebin/Xb8uUGSF/ 20:48
Xliff And what's the best way to report a segfault?

Xliff MasterDuke: And what's the best way to isolate one? ;) 20:50
linkable6 Link: docs.raku.org/type/Parameter
MasterDuke Xliff: i believe a core file you'd just open in gdb directly, you wouldn't want to use rakudo-gdb-m
Xliff: never let it visit its friends. not sure what you mean 20:51
Xliff hah 20:53
I mean: What's the best way to localize the segfault to the area of code that caused it.
20:56 Black_Ribbon joined
MasterDuke it helps if your moarvm is compiled with debugging symbols. catch it in gdb, get a c level backtrace, find the first frame with a `tc` as a parameter, `f <that frame number>`, then `call MVM_dump_backtrace(tc)` 20:57
Xliff Yeah. Unfortunately, this is a long runner. Can't afford the performance hit of gdb. 20:59
Was hoping to catch the moarvm origin at least.
MasterDuke gdb has almost no overhead
Xliff No, but running moar code in rakudo-gdb-m DOES.
MasterDuke huh, i've never really noticed that 21:00
Xliff Yeah. Code is slower when running. Particularly parse time.
And when you are talking between 10-20 minutes (randomly) per occurence when NOT running under gdb... 21:01
That could be a long time.
MasterDuke stick it in a loop overnight>
?
for compiling the CORE.c setting i don't see any slowdown under gdb. but it also doesn't take 10-20min normally... 21:03
RaycatWhoDat Quick question: what was the handle of the person who wrote a compiler in Raku? 21:04
Xliff RaycatWhoDat: That could be several people. 21:05
RaycatWhoDat Ah. Apologies. Andrew Shitov? 21:06

What's the state of standalone binaries in Raku? Is there a recommended way of doing that?
21:09 sena_kun joined 21:10 Altai-man left
MasterDuke RaycatWhoDat: for windows you might be able to use modules.raku.org/dist/App::Install...ment.se%3E 21:11
otherwise i think the work described in yakshavingcream.blogspot.com/ needs to be finished and/or polished 21:12
Xliff Yep! MasterDuke++. I forgot what her nick was. 21:13
RaycatWhoDat Interesting.
I recall LOVE (Lua game framework) allowing for the creation of a "fused executable" by 'cat'-ing the source code onto the application. 21:15
Is this an approach that is feasible in any sense (sans the obvious work involved)? 21:16

MasterDuke you need to push the changes and create a PR (pull request) from your fork/branch to master 22:33
Henri Can I push directly to a branch I've created? 22:34
My branch is only local.
MasterDuke you commit to a branch and push to a remote. did you fork the repo or just clone it? 22:35
you might not have permissions to push your branch if you just cloned it. in that case you want to fork the repo, clone your fork, push your new branch to your fork, and then create a PR from your branch on your fork to the master branch of the main repo 22:36
Henri I just cloned the repo.
