jmerelo Hi 18:52
tellable6 2019-12-23T19:35:01Z #raku <kalkin-> jmerelo the succ & pred stuff is magic. so I guess i need to do a PR which turns the MORE MAGIC switch on this ranges
2019-12-23T20:13:46Z #raku <Kaiepi> jmerelo, i'll get the post scheduled
2019-12-23T20:18:56Z #raku <Kaiepi> jmerelo, oh mb didn't see the emails
jmerelo .tell kalkin- we all need more magic :-)
tellable6 jmerelo, I'll pass your message to kalkin
Poohman do we get to specify the type
jmerelo .tell Kaiepi OK :-)
tellable6 jmerelo, I'll pass your message to Kaiepi
jmerelo I've just published a closing post for this year's advent calendar rakuadventcalendar.wordpress.com/
We've had around 8000 visits, which is quite good. 18:53
During this month, the old Advent Calendar at perl6advent.wordpress.com had 2k visits
Also, this time last year the old AC gathered 16k visits 18:54
Still, not bad for the first time ever, new URL, no incoming search engine queries or links...
But if you don't mind, I'm going to make some changes for next year.
Main change will be that there will be no slots assigned from scratch, the editor (me or whoever) will assign the publishing slots as they are available. 18:55
Also, I'd like to have all, or most, articles available by Dec 1st. 18:56
lizmat seems a fair goal :-)
jmerelo Which I also did this year but, well, I didn't have mine ready and it was assigned for the 6th, so, well...
Anyway, I think that not assigning a day and giving the same deadline for everyone will allow for easier scheduling. 18:57
Nobody that was not an author did notice, but there was a fair amount of rescheduling in the background so that there would be an article ready every day
Also, tbrowder had to write an extra article, for which I'm quite grateful. 18:58
I will also ask everyone to send me an email (one that people actually read) or any other way of contacting, like matrix or telegram, so that I can start to ask for articles by the middle of August 18:59
I meant, ish.
Anyway, thanks a lot to everyone who's written an article this year or any of the others. 19:00
You can still edit it, categorize it, add the 2019 tag and maybe fix something if you so want. 19:01
Linking the official documentation will be specially helpful
We also need help with the CSS edition. Tom Browder also paid for the premium site, so it will be really helpful if we make it seem really nice. 19:02
Since tbrowder paid, we also have a free domain we can use.
Changing it in the middle of the season seemed a bit confusing, but we can do it now.
Please send suggestions to tbrowder

Poohman Hi Lizmat, im trying to map all my members to one sanitising function which will make sure the user input matches my member types 19:54
lizmat that could mean many things :-) 19:55
Poohman The condition i have been using till now is $line.Str.does(Str) or $line.Numeric.does(Numeric)
lizmat so you want to see if something is a Str or Numeric ? 19:56
Poohman Str, Numeric, Date etc - based on the type of my member
lizmat $line ~~ Str ?? 19:57
Poohman ok let me make some checks to see if I can make that work with Date as well 19:59
as simple as that? thanks
chloekek Got a nice commit hash: ffffff1 20:05
.oO( wtfffff1 )
chloekek What a lucky number to be allocated to Raku code. 20:07
Is it possible to enable rakudo profiling using an environment variable instead of a command-line argument? 20:30
I have various bash scripts wrapping my program (to set other environment variables, such as PERL6LIB and PATH), so shoving in that extra command-line argument before the Raku source file name would be inconvenient. 20:31
lizmat perhaps github.com/perl6/nqp/blob/master/d...artprofile is what you're looking for 20:33
but there is no env variable atm

dakkar is that some bootstrapping special case? should that work?
chloekek lizmat: Thanks! MoarVM::Profiler class also seems relevant. 20:40

cpan-raku New module released to CPAN! Sparrowdo::Chef::Client (0.1.0) by 03MELEZHIK
lizmat dakkar: alas, no
dakkar I'll have to wait for some other raku-expert, then ☺ 20:47
lizmat yeah, jnthn comes to mind 20:49
dakkar I *think* it's a bug, but those bits are declared in BOOTSTRAP and that's a bit too obscure for me 20:54
lizmat it's obscure for a lot of people :-( 20:57
dakkar is it even possible to declare a parametric class type? 21:01
lizmat yes, by adding a ^parameterize method ? 21:02
21:02 RobRaku left
lizmat see how object / typed Hashes are implemented 21:02
chloekek … and running into github.com/perl6/nqp/issues/567 again :') 21:05
chloekek is going to look into fixing that 21:06
21:06 RobRaku joined
lizmat ++chloekek 21:07
dakkar lizmat: I can't find any mention of `parameterize` in the documentation… 21:09
lizmat well, that warrants a doc ticket then
lemme see if I can create a gist 21:10
dakkar I found a method by that name in ParametricRoleHOW
(the source)
lizmat m: class A { method ^parameterize(|c) { dd c } }; A[Int].new
camelia \(A, Int)
lizmat m: class A { method ^parameterize(|c) { dd c } }; A[1,2,3,4].new 21:11
camelia \(A, 1, 2, 3, 4)
dakkar ok, so ::A has a metaclass that's not ClassHOW, but a subclass of it with a redefined / extra method?
lizmat dakkar: it is supposed to return the mixed in type, according to the given parameters (and your logic) 21:12
yeah, that's basically what the 'method ^foo() { }' does, as I understand it
m: class A { method ^parameterize(|c) { dd c } }; dd A[1,2,3,4].new 21:14
camelia \(A, 1, 2, 3, 4)
dakkar role Foo[::X] { }; class Bar { method ^parameterize(Any:U $type, *@) { return Bar but Foo[$type] } }; dd Bar[Str].new; 21:17
evalable6 Bar+{Foo[Bar]}.new
dakkar role Foo[::X] { }; class Bar { method ^parameterize(Any:U $type, *@) { return Bar but Foo[$type] } }; dd Bar[Str] ~~ Foo[Str];
evalable6 Bool::False
dakkar uh?

camelia Date.new(2019,12,26)
Poohman Ok Lizmat, but why does Str.new($line) not work - conversely what does the error regarding named arguments mean? 21:20
lizmat first of all, using Str.new to create a string, is really a lot of writing 21:21
in Raku one usually uses the prefix ~ for that
m: dd ~42
camelia "42"
lizmat in Raku, when you create a class, it's "new" method will only accept named parameters
m: class A { has $.foo = 42 }; dd A.new( foo => 666 ) 21:22
camelia A.new(foo => 666)
lizmat m: class A { has $.foo = 42 }; dd A.new( 666 )

chloekek Sure.
Xliff github.com/Xliff/p6-GtkPlus/blob/m...-build.pl6 23:19
I have 1284 compunits in that project.
If I run through the optimized build list here: github.com/Xliff/p6-GtkPlus/blob/m.../BuildList 23:20
It takes around 3200 seconds to compile.
Using that first script I can get that down to 1400 seconds.
chloekek Build in parallel.
Xliff :)
chloekek I’m using Cro and it also takes a long time to build. 23:21
Like five seconds.
Xliff Ooh! What are you using Cro for?
ppft! 5 seconds? I'll take that any day.
chloekek I have a SQLite database with Raku archive metadata and I have a web app that searches it with Cro::HTTP. 23:22
Xliff I've got several single compunits that take around 30 seconds to precompile.
SQLite? Interesting.
Have you checked the performance of that against something like MySQL? 23:23
chloekek I have not used MySQL. I am very familiar with PostgreSQL. SQLite is easier to set up.
23:23 sena_kun left
chloekek I could switch to PostgreSQL but I don’t need it for this project. 23:23
Xliff Ah. I have worked with both MySQL and SQLite3.
Sounds like a cool project. Is there a repo? 23:24
I want to write a web framework based on Cro::WebApp. Just don't know what to put into it... 23:25
I think I have a way to add scope limited routes to the main object. 23:26
Think: extensibility
