Util I am speaking on Perl 6 in 14.5 hours. If anyone would like to review, I would welcome your thoughts. 00:31
hack.p6c.org/~util/secret.pdf
Please don't distribute this version that contains speaker notes.
TIA!
raschipi Util: did you actually roll a dice? 00:36
Util: In page 40, it says it's choosing from 20 sides, but it's from 6 sides. 00:41
Util: On page 95: "We have improved them so much, they extend up into full parser." Perl5 also extended it's regex engine to be a full parser, it's just the worst thing to actually use. 00:48
lucs How do I declare a var that can hold for example an Int or a Foo?
lookatme my $bar where * ~~ Int | Foo; ? 00:49
or using subset
lucs Okay, cool. Thanks. 00:50
00:51 lindylex joined
raschipi subset IntorStr of Any where * ~~ Int | Str; my IntorStr $x; 00:51
lucs Neat, thanks.
Really Cool, eh :) 00:52
raschipi If you are planning on using that in a signature, you can also go with multidispatch 00:57
01:00 lindylex left
lucs raschipi: Yep. 01:01
raschipi multi foo (Int $x) { say "Int"; samewith ~$x }; multi foo (Str $x) { put $x }; foo 3; foo 'a' 01:04

m: multi foo (Int $x) { say "Int"; samewith ~$x }; multi foo (Str $x) { put $x }; foo <3> 01:05
camelia Ambiguous call to 'foo(IntStr)'; these signatures all match:
:(Int $x)
:(Str $x)
in block <unit> at <tmp> line 1
01:06 Kaiepi joined
raschipi Or you can add a Numeric method to foo and then cast in the signature, TIMTOADI after all. 01:06

timotimo Util: it might be you really want to show off sort with a single argument, but you could also .roll(5).sort.tail(3) 01:42
also, we no longer require the \ at the end of the line to make method calls go in the next line! \o/
Util raschipi, timotimo: Thanks! 01:45
There is some classic blunder related when coders are holding forth on bad code they have inherited.
The "I rolled a die" line is from my (flawed) memory of such a story.
*I* did not roll, I just made a reference which is perhaps too obscure. I cannot find it on DailyWTF.
01:45 molaf_ joined
timotimo it's an xkcd actually 01:45
well, there is an xkcd with that exact thing in it
raschipi xkcd.com/221/
Not too obscure since at least two people here knew the exact source... 01:46
Util That may be where I know it from. Woohoo!
(I *did* remember the right integer) :^) 01:48
raschipi Util: The only thing I'm missing from your slides a conclusion. You start with a good introduction, goes into examples and then it just ends.
timotimo m: .say for "1 2 3 4 5 6 7 8 9 10 11 12".match(:g, / <{ 3 .. 11 }> /)
camelia ｢3｣
｢4｣

｢8｣
｢9｣
｢10｣
｢11｣
timotimo Util: how much better is that for your tokens year, month, and day? :) :)
though not sure if it does anything with fancy unicode numbers, but <.digit> also does that, doesn't it? 01:49
01:49 jeromelanteri left
timotimo oh, you want 01 there 01:49
m: .say for "01 02 03 04 05 06 07 08 09 10 1 2 3 4 5 6 7 8 9 10 11 12".match(:g, / <{ "03" .. "11" }> /) 01:50
camelia ｢01｣
｢02｣
｢03｣
｢11｣
｢12｣
timotimo nope.
forget i said anything ;)
Util raschipi: Slides 165-167 are the "reveal" of where I have been going with my narrative.
raschipi Just need to tie that into the introduction, then. Just conclude the good design leads to a qualitative change on how people program. 01:52
timotimo Util: on page 118, the palindrome one, you can actually omit the parens before the method call if you put a space before the .
m: say ^100 .grep({ $_ eq .flip }).elems
camelia 19
Util timotimo: I looked at matching '01'..'12'. Look at how they have changed it (while I was not looking):
m: say ("01".."12").list;
camelia (01 02 11 12)
timotimo m: say flat("01".."09", "10".."12") 01:53
camelia (01 02 03 04 05 06 07 08 09 10 11 12)
timotimo m: say "01" ... "12" 01:54
camelia (01 02 11 12)
timotimo ok, ... doesn't do it differently 01:55
m: say "01", *.succ, ... "12"
camelia Potential difficulties:
Comma found before apparent sequence operator; please remove comma (or put parens around the ... call, or use 'fail' instead of ...)
at <tmp>:1
------> 3say "01", *.succ,7⏏5 ... "12"
12
in block <u…
timotimo m: say "01", *.succ ... "12"
camelia (01 02 03 04 05 06 07 08 09 10 11 12)
Util timotimo: re:"omit the parens" I am happy to learn that for myself. I will keep that slide as-is, since I am showing off the error. 01:56
timotimo right
on 156 the notes say "my guarantee to the compiler that they are equal size", but that sounds like the compiler will blindly trust you; it will actually throw an exception if the sizes mismatch 01:57
Util timotimo: thanks. When I gave the talk last week, I added "it will complain if they are not (of equal size). I will add it to the notes. 01:59
timotimo OK
other than that it looks like a good talk
raschipi It does look like a good talk, we're just bikeshedding the details. 02:00
timotimo i mean even the things we've mentioned aren't dealbreakers at all
Util raschipi timotimo: You have both given me several points that I intend to adopt. 02:02
raschipi: the "tie-in" I will have to think more on. I do see your point. 02:03
timotimo oh, and saying rakudo is written in itself may oversell it a little 02:05
raschipi timotimo: I disagree with you on that. Rakudo is written in Perl6, he didn't go into self-hosting where it gets a little more complicated. 02:07
timotimo but the grammar, actions, world, compiler bits are all nqp? 02:08
anyway, i'm going to sleep 02:10
have a good one, and good luck on the pres, Util :)
raschipi g'night
Util timotimo, raschipi: Much thanks! 02:14
02:41 benjikun left, benjikun joined 02:49 kjk joined
kjk I have a sub that takes a regex as an argument and smartmatch(!~~) against it. Is it possible to write my regex argument such that the sub when !~~ $myregex effectively matches the complement of $myregex 02:55
raschipi You want everything not matched by the regex? 02:59
kjk hmm, I think I'm not explaining my question clearly. Basically, I want to move the ! of !~~ into $myregex somehow
geekosaur not really. that's always been difficult for regex 03:00
kjk yeah, ic. ok thanks anyway 03:01
maybe I'll make my the parameter also accept a callable instead, that way it's not restricted to matching regex. 03:06

Zoffix lucs: lookatme raschipi instead of `where * ~~ Int | Foo;` use just `where Int | Foo`. The `where` clause already smartmatches so adding a second smartmatch is redundant. Also, the `where Int|Foo` form is actually optimized into two typechecks, whereas the other form would involve invoking a callable each time 11:27
raschipi You're completely right, and I didn't even see it, just copied and pasted it. 11:28

tbrowder_ anyone here use emacs and perl6-mode? i’m going to try to fix HEREDOC indentation and need some user feedback. 12:09
AlexDaniel yes?
tbrowder_: btw what's currently the difference between github.com/perl6/perl6-mode and github.com/hinrik/perl6-mode 12:10
the one in perl6-mode has more commits I think, but which one is installed for most of the users? 12:11
hmm melpa.milkbox.net/#/perl6-mode
I guess perl6/ org one
ok
tbrowder_ when you write a HEREDOC chunk do you (1) want emacs to leave everything as is inside the HEREDOC or (2) align any text outside the left column of the ending HERE token? 12:12
to your question, our perl6-mode has diverged from henrik’s. 12:13

Does the current behavior satisfy you? 12:24

Later I’ll make a gist showing some examples of what I mean. Maybe we could have a HEREDOC style selector... 12:27

Andrew_ Hello there, I'm new to perl6 (at this moment I'm lerning :D ) and I would like to know what path should I take for web dev. with perl? 16:27
lizmat Andrew_: you probably want to have a look at Cro
cro.services
El_Che Cro is hte way to go atm 16:28
timotimo github.com/jnthn/cro-webapp - cro itself doesn't have sugar for templating yet, but this is a work-in-progress that may become part of cro itself for developing web apps specifically
Andrew_ nice, thanks 16:29
but i heard something about catalystframework?
timotimo so you'll want to find a templating engine that you like, if you don't use Cro::WebApp. there shouldn't be any obstacles to just using any templating library you find
that's a perl5 framework
Andrew_ hmm 16:30
jnthn I actually have that templating engine running in production already, so it's stable in that sense at least. :-)
timotimo perl5 and perl6 are quite different, both have different strengths and weaknesses
Andrew_ so which one should i chose? 16:31
for web
between perl5 san perl6
timotimo i guess it depends on what your specific requirements are 16:32
like, do you expect very high traffic? 16:33
16:33 dakkar left
timotimo how complex is the business logic in your web app going to be? 16:33
Andrew_ high trafic and complex business :)) 16:34
timotimo i should have specified, what's "high" to you?
Andrew_ let me rephrase everything :))
I will start an intern in perl web dev in about 1 month and i wanna prepare a little 16:36
16:36 domidumont joined
timotimo ah, if you're going to be working a job, it's likely that they will employ perl5 rather than perl6 16:36
i.e. if they have existing code and are not explicitly mentioning perl6, they are likely using perl5 16:37
learning perl6 can help you become a better programmer, certainly, but since you've got a limited time budget, you should invest that in learning perl5 first, i'd imagine
Andrew_ Catalyst, Dancer2 or Mojolicious
i found these 16:38
timotimo TBH, i haven't done any perl5 yet
but those three are very popular indeed
16:38 sno left, webstrand left
Andrew_ well :)) what should i chose? 16:38
uzl Hi, everybody!
16:38 perlpilot joined
timotimo sorry, i can't help with that decision :( 16:39
timotimo AFK
Andrew_ thanks anyway
tadzik Mojolicius will allow you to write both dancer-style and catalyst-style apps
hoelzro Andrew_: I really like Mojolicious
timotimo YW, and good luck with the internship!
hoelzro (FWIW)
16:39 webstrand joined
tadzik I'd say it's a good option :) 16:39
Andrew_ okey so i should start with that
timotimo just pray to god their existing code isn't a "web app" based on CGI.pm :) 16:40
Andrew_ thank you very much!
:)) i don't know anything about that for now:D
uzl I'd like to configure the constructor "new" so that it doesn't take any arguments and create a new constructor with a different name. Not sure how to get around it.
timotimo uzl: a constructor is really just any method that calls bless, either indirectly or directly 16:41
so put a method new() { say "no" }; method constructor($a, $b) { return self.bless(a => $a, otherattr => $b) } 16:42
uzl timotimo: ok, i'll try that!
timotimo: I've been reading the docs and I'm not sure in which situations I'd use bless, BUILD, or BUILDALL. 16:43
timotimo you probably won't override BUILDALL more than once in your whole life ;)
16:44 lex joined
timotimo BUILD is required when you want to access private attributes, because they are not accessible in a regular constructor 16:44
bless is what you call to actually create an instance, and bless will call BUILDALL, which is responsible for calling the BUILD method of all classes in your hierarchy
16:45 Andrew_ left
uzl timotimo: for most situations, i should be fine with bless and BUILD, meaning I don't need to touch BUILDALL. 16:45
?
jnthn You pretty much never need to touch BUILDALL 16:46
lizmat uzl: or use bless, for that matter
just a BUILD method or a TWEAK method is usually enough
timotimo oh, how could i forget TWEAK 16:47
TWEAK is almost always better than BUILD, because it doesn't make your default values and such on attributse "go away"
uzl lizmat: going back to doc to read about TWEAK ;)
Thank you, guys! 16:48

Zoffix kjk: basically, there's no Mu:D candidate to make junctions thread, buuut, we can have that and still have a Mu:D candidate. You can fix the bug by changing `Any` to `Mu:D` here: github.com/rakudo/rakudo/blob/mast...Mu.pm6#L16 and then adding another candidate for junction threading: multi method ACCEPTS(Mu:U: Junction:D \topic) { topic.THEAD: { self.ACCEPTS: $_ } }

timotimo doesn't the junctive fallback have to go through the slow-path binder?
Zoffix yeah
timotimo and it has to figure out which argument has to be threaded, and it has to look through all of 'em to find the right one, too

hoelzro thanks!
El_Che hoelzro: I'll try the fix once rakudo is out, that's why the setup would be identical to my install and more likely to be in the situation to trigger the bug 19:37

thx in advance 19:39
hoelzro happy to help!
El_Che happy to see it fixed
hoelzro thanks again for helping me walk through it
AlexDaniel El_Che: should I merge the release branch into master now so that the fix is in master also?
El_Che the fix should be released 19:40

AlexDaniel El_Che: not really 19:43
AlexDaniel does it
El_Che hoelzro: my linux pkgs have rakudo + zef. I am considering adding Linenoise or Readline to the mix, so people have a minimal setup. Plus for Linenoise: self contained C lib; minus: dependencies on other Perl 6 dependencies that should be included (there goes the minimal).
hoelzro: Plus for Readline: no perl6 module deps; minus: external C dependencies that would result on a dependency for the packages (they have none at the moment) 19:44
AlexDaniel El_Che: done
El_Che AlexDaniel++
I will create minimal docker images, that can easily have a few deps included, but for the pkg I am more conservative 19:45
hoelzro El_Che: tbh, I forget which Perl 6 stuff I rely on for Linenoise =/
I think it's stuff for building the Linenoise lib
El_Che It looks like it 19:46
I will look into it more in detail
hoelzro sounds good 19:47
El_Che the compile it at install time trick is nice :) 19:48
it works around the problem readline has
hoelzro well, it helps that Linenoise has a much more liberal license
(actually, I guess it doesn't - readline is GPL, which means the Readline module needs to be too, right?) 19:49
El_Che and is small
hoelzro yeah - that's why I chose linenoise
El_Che readline is already installed on most system
the trick is that often more versions are installed
both versioned and no naked .so 19:50
to the perl6 bindings break
I have a 1 line fix fork that makes it work with libreadline7, but it means older versions are out of luck
uzl Earlier I asked about object construction and although I read the docs again (and followed the advices), I am still lost. 19:51
The class I have has only private attributes. I'm planning to customize the constructor "new" so it
doesn't take any arguments. However, when it's called on the class it should return an object with the attributes
initialized to some default values. As for the second constructor (let's call it "create"), it should take
named parameters and initialize the private attributes.
El_Che the non versioned perl6 code does not find 5 or 7 (what's on debian and opensuse) and seems to expect 6 (dunno how)
uzl: you can pass arguments to new and do stuff with the passed arguments 19:57
looks way easier, but of course you can do what you write
I am pretty sure people mentiones BUILD and TWEAK already 19:58
I don't see the problem with passing construction data to new 19:59
you don't have to offer a getter for those things if not needed
geekosaur the main problem is BUILDALL, I think. your class can't inherit (not even from Any or Mu) if you don;t replicate that in your custom new
iirc; there;s been some changes there 20:00
uzl geekosaur: I won't be subclassing the class. 20:01
timotimo geekosaur: i'm confused by what you're saying. how do youm ean "replicate" in "your custom new"?
20:02 Zoffix joined
Zoffix uzl: I tend to define private method !CREATE-SELF and bind to privates through it 20:02
geekosaur timotimo, did this change? default new calls BUILDALL which constructs the actual object. including standard object behaviors inherited by BUILDALL calling the new from Any and Mu?
Zoffix uzl: !SET-SELF rather, but name doesn't matter
geekosaur I think it's still documented that way
Zoffix m: class Foo { has $!meow; has $!moo; method new { self.bless }; method !SET-SELF(:$!meow, :$!moo) { self }; method create { self.bless!SET-SELF: |%_ }; method z { dd [$!meow, $!moo] } }; Foo.new.z; Foo.create(:42meow :100moo).z 20:03
camelia [Any, Any]
[42, 100]
timotimo bless calls BUILDALL, the default new calls bless
so all you need to do is call bless
uzl Zoffix: Will take a look at that.
Zoffix Calling .bless won't save private attrs tho 20:04
m: class Foo { has $!z; method new { self.bless: :42z }; method d { dd $!z } }.new.d 20:05
camelia Any $!z = Any
Zoffix m: class Foo { has $!z; method !SET-SELF(:$!z) { self }; method new { self.bless!SET-SELF: :42z }; method d { dd $!z } }.new.d
camelia Int $!z = 42
Zoffix s/save/set/;
uzl El_Che: I could pass construction data to "new" but I want to customize it so that it sets the attributes to some default.
Zoffix uzl: FWIW, you *are* aware that you can give defaults to attributes right in their definition, right? 20:06
m: class Foo { has $.meow = 'foos'; has $.bar = $!meow.uc.flip; }.new.Capture.say
camelia \(:bar("SOOF"), :meow("foos"))
Zoffix uzl: and I didn't follow earlier discussion, so I don't know if it was mentioned already, but there's also submethod TWEAK where you can tweak the attrs 20:07
uzl El_Che: I want the other constructor to show some intent. For example, MyClass.from-keysheet( data => "", etc.); 20:08
Zoffix m: class Foo { has $.meow = 'foos'; has $.bar; submethod TWEAK { $!bar = $!meow eq "foos" ?? "tis teh foos" !! "something else"} }.new.Capture.say
camelia \(:bar("tis teh foos"), :meow("foos"))
Zoffix m: class Foo { has $.meow = 'foos'; has $.bar; submethod TWEAK { $!bar = $!meow eq "foos" ?? "tis teh foos" !! "something else"} }.new(:42meow).Capture.say
camelia \(:bar("something else"), :meow(42))
El_Che uzl: intent is more for a method, I would say
uzl: anyway, perl6 is flexible enough to do whatever you need :)
uzl Zoffix: i'll have to look more closely to your examples, Zoffix! 20:09
Zoffix m: dd say List.from-iterator: ^10 .iterator
camelia (0 1 2 3 4 5 6 7 8 9)
