ShimmerFairy gfldex: I don't know what the solution to that is, but might I suggest self ne '' ? :) Or even $_ ne '' with self (so you don't compare a normally-undefined string) 00:28

gfldex that's the solution (nearly)
m: subset NonEmpty of Str where * ne ''; sub foo(\s -->NonEmpty){ Nil }; say foo 'abc';
camelia rakudo-moar 234aa4: OUTPUT«Nil␤»
gfldex nearly, because of the dreaded Nil 00:30
ShimmerFairy ...but didn't you just force Nil there?
gfldex m: subset NonEmpty of Str where { fail('Nil!') if $_ == Nil; $_ ne '' }; sub foo(\s -->NonEmpty){ Nil }; say foo 'abc'; 00:31
camelia rakudo-moar 234aa4: OUTPUT«Nil␤»
gfldex I did force Nil but I want it to blow up properly on Nil
Nil is worse then a non-empty string in a sub that is supposed to return a non-empty string 00:32
ShimmerFairy m: say Nil eq ''
camelia rakudo-moar 234aa4: OUTPUT«Use of Nil in string context in block <unit> at <tmp> line 1␤True␤»
gfldex as soon as return spots a Nil it will skip the return type constraint entirely 00:33
the whole idea of runtime return value checks is that it fails early and the error message/exception is local to the sub that is causing the problem 00:34
Nil makes that very difficult 00:35

ugexe nine: when trying to use a custom CUR I can get `require <tar#lib/Root.pm6>` to load Root.pm6, but `require <tar#lib/Root/UsesRoot.pm6>` fails to load Root.pm6. The problem is that my CUR::Tar.load only gets called for `lib/Root/UsesRoot.pm6` which never calls CUR::Tar.load again period (I expected it would but with a short-name). Any idea what I'm forgetting to do? 01:43
as an example of the failure see the last line of github.com/ugexe/Perl6-CompUnit--R...01-basic.t

nicq20 Sorry to barge in here with questions, but I'm having trouble understanding how Perl6 is compiled with rakudo on the MoarVM. Is that like C compilation, or more like JIT compilation? 01:52
MasterDuke i'm not a core dev, so take what i say with a grain of salt, but it's more like JIT (there is in fact a JIT) 02:00
02:01 molaf joined
nicq20 Huh. Ok, some people will talk about it like it does a C-like compilation, so I was not sure. I mostly hear that with modules. 02:02
02:04 noganex_ joined 02:05 yoleaux joined, ChanServ sets mode: +v yoleaux

sammers is there a way to set a base collection of paramaters that all multi subs will use? 04:02
04:04 aries_liuxueyang left
sammers for example, I want all multi sub foo() to use Str :$bar, Str $:baz, plus their custom params 04:04
so their signature will always include :$bar, :$baz, plus their unique params. 04:05

sammers parabolize, thanks, I am actually looking to use this for MAIN 04:39
parabolize you could probably do something with a Capture 04:40
my $defaults = \(Str :$bar, Str :$baz)
sammers I want to create a few base params that are applicable to all multi MAINs
ok, I will take a look 04:41
parabolize sammers: nevermind my non-sense about Captures, proto is what you want 04:44
docs.perl6.org/language/functions#proto
Captures are the calling side not the receiving. XD 04:45
sammers ok, I am messing around with proto now. Is there a way to predefine a set of paramaters to be passed around? 04:46
I guess something like a code object...

sammers is there a way to detect when a value is passed to a sub that doesn't match a where {} test? 05:56
I am using this with MAIN and trying to detect if one of the values passed matched, but all it does is print usage when no match. 05:57
ShimmerFairy sammers: you would need a multi sub, where the other sub catches a failed 'where' test. 05:58
sammers ah, ok 05:59
ShimmerFairy m: multi sub foo($a where 4) { say $a }; multi sub foo($a) { say "OOPS" }; foo(4); foo(3) # an example

sammers is there anyway to have the generated usage print out valid values for each signature paramater? without having to manually define usage. 06:07
06:13 rindolf left, Khisanth left
ShimmerFairy sammers: I'm not sure, I think you'd have to define your own USAGE to do that. 06:15
sammers ShimmerFairy, thanks. Do you know if there is a scoped variable that stores parameters and their values? something I could loop on for example. 06:19
06:20 rindolf joined
ShimmerFairy I don't think there is, unless (I *think*) you define a sub with no signature and then can use @_. Or, if you're talking about command-line inputs, there might be some kind of @*ARGS variable. 06:20
sammers like sub foo($name, $age) { for %params.kv -> $param, $value { ... } } 06:21
yeah, there is @ARGS... hmm

ShimmerFairy I hope Bobby Tables lent an inspection to that subdomain. 09:25
moritz timotimo: and of course, there's no possible ambiguity with backslash for escaping in string interpolation... 09:26
timotimo yeah, because you can't put namespaced things into strings
09:26 domidumont joined
moritz of course not 09:27
composability? nope
timotimo i'd advise making namespaces traversable with an API instead of string literals 09:28
ShimmerFairy timotimo: how about the Str class API? :V
timotimo Str doesn't have anything to do with packages/namespaces :)
ShimmerFairy timotimo: it could if you want it to :P 09:29
timotimo i'm the language designer, of course
ShimmerFairy And of course, now infix:<::> is a synonym for infix:<~>, so people's package-manipulating code isn't confusing: $scope = "Foo::"; $pkgbar = $scope :: "Bar"; 09:33

pmurias ShimmerFairy: v8 doesn't use an AST in it's least optimizing compiler too 09:49
timotimo right, it works pretty much directly on the source, doesn't it?
pmurias it has a bunch of compilers, the least optimizing one just emits machine code from the parser 09:51
timotimo OK
pmurias just like PHP seems to be emitting bytecode from the parser and they now plan to add an AST in between
09:52 rurban_ joined
ShimmerFairy It probably says something that the _least_ optimizing compiler foregoes ASTs, though :) 09:53
pmurias ShimmerFairy: they do it to emit code as fast as possible 09:54
moritz it really depends on the language whether you need ASTs or not 09:56
ShimmerFairy I guess I'm so used to ASTs being the way to go that seeing PHP take decades(?) to get around to it seems funny :) .
09:59 araujo left
nine FWIw Perl 5 doesn't have a real AST either. Though its op tree is at least accessible to user space code and allows for pretty cool manipulations. 10:02

camelia rakudo-moar 774e2d: OUTPUT«42␤»
Zoffix Seems to work
jkramer, BTW, things inside arrays and hashes are still mutable by default
m: my %hash = foo => 'bar'; sub (%h) { %h<foo> = 'meow' }(%hash); dd %hash 10:58
camelia rakudo-moar 774e2d: OUTPUT«Hash %hash = {:foo("meow")}␤»
hahainternet do you need the 'sub' syntax if you're immediately calling? are there no bare blocks in perl6?
oh, no that works 10:59
jkramer Alright, thanks for explaining!
Zoffix m: my %hash = foo => 'bar'; -> %h { %h<foo> = 'meow' }(%hash); dd %hash # there are
camelia rakudo-moar 774e2d: OUTPUT«Hash %hash = {:foo("meow")}␤»
Zoffix Just a habit
And you can't `return` from a block

gfldex can i provide a URL on X<>? 13:20
13:21 donaldh joined
BrokenRobot Not at the momemnt, but it's a direly needed feature. 13:21
13:21 Tushar_ left
BrokenRobot Probably something added in Pod::To::HTML 13:21
moritz what would that do?
gfldex X<> would need to create a uniq id in <a/>
BrokenRobot moritz: ability to link to a reference in the document. 13:22
gfldex right now using the search field on anything created by X<> lands on the page where the X<> was in a .pod
you can't jump down to the actual <a name="your-index-entry"> because there is no <a/>
moritz BrokenRobot: you mean something like latex's \ref? 13:23
gfldex yes
BrokenRobot I don't know anything about latex.
moritz but wouldn't that be a feature of L<...> instead?
I mean, X<...> are the anchors, not the links to the anchors
13:24 skids joined
BrokenRobot Not really. There's nothing in the generated markup to indicate where there was an X<> 13:24
MafProd_ Has anyone recently tried to install JSON::RPC recently on Linux? Panda fails on a test with a MAST::Frame error.
BrokenRobot So you can't contruct a link to that portion of the HTML document
gfldex that is not true, there is a <span name="not-so-uniq"/>
MafProd_ I tried on different distro's and keep getting the same error.
BrokenRobot MafProd_: someone else had that error too
nine gfldex: you don't need an <a/> for jumping within a document. Any element with an id is enough.
moritz BrokenRobot: right. But that means X<> must construct the anchor
BrokenRobot: and L<> the link to that anchor
gfldex <a> can have a name= that doesn't need to be uniq
MafProd_ Could not find anything usefeull in google. 13:25
BrokenRobot MafProd_: do you actually need that module or are you just trying to install Task::Star?
gfldex and we need uniq ids because they can collide with <a/>s provided by =head
nine gfldex: but a non-unique name is not as usefull for navigation, isn't it?
gfldex it's better then nothing
MafProd_ BrokenRobot, I was trying to install Task::star
13:26 mohae_ left, nowan left
BrokenRobot MafProd_: it's just a collection of modules. You don't need it for functional Perl 6. You can install any individual modules from it. There're in this list: github.com/tadzik/Task-Star/blob/m...TA.info#L5 13:26
MafProd_ BrokenRobot : I'll give that a try. Thnx. 13:27
gfldex the problem is that forcing uniq ids/name attributes would require the build to fail on non-uniq values. LaTeX is solving that problem by not being parallelable. 13:28
BrokenRobot Are we actually paralleling a build of a single pod? 13:29
13:29 nowan joined
moritz one could always return a set of anchors, and fail at thread/promise joining time when there's a conflict 13:29
gfldex BrokenRobot: not right now because of thread-knots 13:30
moritz though that's more complicated for sure
gfldex i will create a list of all X<> anchors to see how many dupes we actually got
we could also prefix the ids with your-file.pod-- to create uniqness 13:31
13:31 lizmat left
BrokenRobot gfldex: but they only need to be unique per file. 13:31
gfldex they may have to be uniq in the search.js . Not sure how that is actually created. 13:32
BrokenRobot If that's the case, that'd be search.js's problem, not Pod::To::HTML's 13:33
13:35 z3ndrag0n joined

.oO( Why is JSON::RPC in Task::Star .... )
 13:54
tadzik is it not in regular-star? 13:55
BrokenRobot What's regular-star?
tadzik rakudo star
the actual release, unlike the module that mimicss it
nine It is. But why?
Doesn't sound like a module that most or even many users will need. 13:56
tadzik it was probably considered usable and useful :)
I don't think Star ever really had a guideline of what's worthy and what's not
iH2O seems youre investing lots of efforts in this new usable/useful cult version folks B-) 13:57
nine Well to me Task::Star seems like just a list of the modules that at one point worked.
BrokenRobot I was under the impression the actual release just ran panda install Task::Star :)
timotimo no, it ships the modules in a specific version
tadzik no, that's why they're out of sync :)
ugexe nine: it has a path-spec. the problem is because after it is successful in loading the byte code for tar#lib/Foo/Bar.pm6, the code inside tar#lib/Foo/Bar.pm6 will have just `use Foo::Bar` which doesn't match the path spec anymore but it is inside the same tar archive. so it feels like im simply missing one step somewhere
BrokenRobot I see.
ugexe er s/use Foo::Bar/use Foo/ 13:58
tadzik I created Task::Star because I wanted the same set installed but didn't use Rakudo Star
BrokenRobot Sure. I guess my question should've been
tadzik since then I mostly rely on pull request and manual reports about things that change about Star modules
BrokenRobot
.oO( Why is JSON::RPC in R* .... )
tadzik :) 13:59
BrokenRobot :D
moritz because there isn't a real vision for *
ugexe like maybe `use lib "/x/y/x.tar.gz"`
nine ugexe: I know it has a path-spec. But that currently creates a spec that starts with the repo's short-id. The perl6 process that precompiles won't find your repo class with that short-id. You need the full class name instead.
14:00 mr-foobar joined
moritz and in the beginning, we had so few modules that we just included whatever seemed working and somewhat usable 14:00
nine ugexe: Also why is that require "tar#lib/Zef.pm6" in the first place and not just require Zef;? 14:01

ugexe: or alternatively: use lib 'CompUnit::Repository::Tar#zef.tgz'; use Zef; 14:05
I'm just not sure if use lib already handles all the magic needed. Will have to check that.

Ven_ because the non-nice thing is thing:
timotimo you'll always get a container that you can bind into 14:17
you want :exists
Ven_ nope
moritz the default value for accessing a non-existing hash element is Any, and Any.list is a one-element list containing Any
timotimo m: my %h; for %h<foo bar>.list { $_ = 5 }; say %h
camelia rakudo-moar d4ac15: OUTPUT«{bar => 5, foo => 5}␤»

Ven_ ^ that works. But if 'a' doesn't exist as a key, you'll get a loop iteration.. "for nothing" 14:18
(which, in my recursive case, means an infinite loop...) 14:19
14:19 ParsonsNose left
moritz Ven_: use "is default(Empty)" or "is default(())" on the hash declaration 14:20
we do have to the tools to bend the language to your will.
Ven_ oh, we have the tools. I'd rather not have to use them for such a simple thing, though..
iH2O i thought i was stable 14:21
it was stable
Ven_ my expectations of lists are still a bit wonky, maybe? I don't understand why %h<foo>.push: 3; creates a $[] still..
moritz: I can't even do that, it's read from another thing and passed with %()
if $tree<children> { for $tree<children> {} } it is ... :[
moritz for $tree<children> // () 14:22
Ven_ that won't work. $tree<children> is a $[]. I can't "for" it.
[16:18] <Ven_> m: my %h; %h<a>.push: 1; %h<a>.push: 2; %h<a>.push: 2; say %h<a>.perl; for %h<a> { .say } # only one element, wut?
^ confusing to me
moritz for @($tree<children> // []) 14:23
yes, ugyl
Ven_ sorry for beating a how-so-dead horse at this point. but the solution feels a bit icky 14:25

15:02 cdg joined
gregf_ would i be right in saying, the Garbage Collector cleans up containers? 15:02
im sorry for being so vague, *coming from a java/spring background and containers mean something quite different*
if a container is just an object then that would just be it ;) 15:03
nine gregf_: nope. At a level as low as the GC, containers are just plain objects
Ven_ gregf_: a container contains a value. The value can be "42". 42 is an integer, and is not assignable by itself -- it's only a number! The container is the part that does the storing, and provides = (as well as ++, etc). 15:04
nine gregf_: you can think of it this way: a variable is just a name for a container. The container may store a value and you may replace that value.
Ven_ you can't write "42++" – because it's a value, without a container. but "my $a = 42; $a++;" makes sense, because the container's value can be changed (to 43)

BrokenRobot ilmari: rt.perl.org/Ticket/Display.html?id=126732 16:52
timotimo the thing is, lone unicode characters hanging around in your code just get their number attribute taken and interpreted as the number
BrokenRobot m: "²".uniprop.say
camelia rakudo-moar d4ac15: OUTPUT«No␤»
BrokenRobot Aye
ilmari but why doesn't the whole string of superscript numbers become the number?
why isn't ²² == 22?

BrokenRobot And superscripts numbers are handled differently.
timotimo aye, they aren't decimal
BrokenRobot So to me this now looks like not a bug. Just a curious artefact of the fact that we can use things like ⑤ that become a number 16:54
m: say ⑤²²
camelia rakudo-moar d4ac15: OUTPUT«2384185791015625␤»
ilmari smells like overgeneralisation to me

TimToady to me it's just a DIHWIDT 16:55
BrokenRobot And this bugs out because there is no handlings for postfix ⑤ nums
timotimo yup
we can certainly make the parser a bit smarter about this situation 16:56
and give a more helpful error message
like "⑤ cannot be used as if it were decimals"
TimToady but why would anyone write that in the first place, other than fiddling around?
BrokenRobot Indeed.
TimToady I suppose one could get out of sync with term/infix
BrokenRobot "Doctor, It Hurts When I Do This" ? 16:57

BrokenRobot Oh, "stop doing that"? D
ilmari the problem is that it doesn't hurt when you do ³², it's just silently wrong
TimToady which hurts :) 16:58

SSH tunnel protects you only from your ISP, not anything upstream
proper SSL provides PFS 17:45

BrokenRobot let's encrypt is not free.

hahainternet somewhat, but it's SSL
it's not that different
the req script is a little odd, but it lets them automate things which is understandable
vendethiel the docs say:

timotimo it's important to be able to use :!v because you could be using something like :v($shouldskip) 17:54

vendethiel TimToady: I gather they are, but.. oh timotimo++ clarified
timotimo for performance reasons mostly, but also because it's a little bit wordy
vendethiel he's too fast!
TimToady mostly, the default semantics of subscripting are driven by the idea of not throwing away positional information that might be important 17:55

buharin DrForr, no I want to write my own 18:40
DrForr I'm sure someone out there is interested in reinventing the wheel, but given how much traction Docker, Chef and Puppet have in the market it'd be an uphill battle. Not saying nobody is interested, just that it's hard going. 18:42
perlpilot DrForr++ well said. I was trying to think of a good way to say just that :) 18:43
buharin oh you said
DrForr Do you have an angle that nobody's considered? 18:44
buharin Chef and Puppet
I didn't know these
moritz that's a bit of a category error
Chef and Puppet are configuration management systems
buharin I don't like Docker
moritz not a container engine, like Docker, LXC or Rocket
buharin overtime when I do something with it 18:45
DrForr Yeah, those aren't container systems, I couldn't think of other systems.
moritz or BSD Jails
buharin it is overcomplicated
moritz or Solaris zones

DrForr Well, that's not going to help much for perl 6 users. Maybe ask over ---> there in #perl? 18:51
perlpilot buharin: 1) that's running a perl that's kinda old (5.010) and 2) what DrForr said.
buharin DrForr, I should definitely change my job ;P I had always a problems like "go do this" and when I stack more than hour then they said ok don't do that it takes too long 18:52

bbkr nine: this issue is caused by "try require". in this case in LWP::Simple there is "try require IO::Socket::SSL; ". if I load it in my Zonk.pm file explicitly earlier - "use IO::Socket::SSL; use LWP::Simple" then everything works
21:06 rurban left
bbkr nine: so that is not an issue inside JSON::RPC. And I'm not sure if I should hack it by adding "use IO::Socket::SSL" because that would add dependency from outside Star 21:07

Xliff Why is it that method new() only takes named arguments? 23:51
I'm getting the following when I use "callwith" in method new(): Default constructor for 'Winamp::ML::Index' only takes named arguments 23:52
23:52 Zoffix left
Xliff Trying to define method new as a multi. 23:52
ugexe because the default constructor doesnt have named positionals declared? 23:53
23:53 bjz joined
Xliff So method new must use named parameters? 23:53
ugexe well positionals
TimToady only named args work well with polymorphism
Xliff *sigh*
TimToady especially under MI
Xliff MI? 23:54
Multi Inheritance?
TimToady multiple inheritance, which we support, vaguely
ugexe if it doesnt have a method new($xxx), then its arguments are the names of its attributes
Xliff OK. No MI
TimToady but we can't guarantee that any base class will not participate in future MI
Xliff ugexe: "multi method new(Str $fn)" and "multi method new(IO::Handle $fh)"
Str new method calls IO::Handle new method once file handle is opened. 23:55
TimToady you can have special purpose positional constructors, but they must translate to named if you wish to fall back on the underlying apparatus
Xliff Str method new uses callwith() to move things along
ugexe m: class Foo { multi method new($x) { say 1 }; multi method new ($x, $y) { say 2 }; }; Foo.new(1); Foo.new(1,2)

Well, you aren't trying to use callwith() in your example. 23:57
