BenGoldberg While having placeholder arguments sorted alphabetically makes intuitive sense, istr them being documented as being used in order of appearance... that is, both of the above two ought to produce the same output. 00:25
ZoffixLappy If they're documented that way, it's an error that should be fixed. Perhaps, you're confusing regex captures? 00:29

cschwenz isn't there a port of Getopt::Long?
RabidGravy I think so 07:20
_nadim There is, completely undocumented but i wrote "format of options are unknown"

07:21 tardisx left
_nadim I did that, Getopt:::Long is not documented, Getopt::Tiny makes the same mistake as P5 and the doc is, well, fuzzy, Getopt::Type doesn't fit the work. 07:21
I smell a Getopt::Whatever module coming 07:22
RabidGravy yes I think you need to read some code
and/or help make one of the existing modules do what you want 07:23
07:23 zhmylove joined
_nadim I read the codes, and if there is nothing available, Getopt::Whatever will come, but it would be a pitty to no use what already exists. 07:23

moritz well, there is a use case for string bitwise ops
for example if you want to to find borders in a text table
you can start with chr(255) x 80, and ~& every line 09:36
and see what columns remain in the end
if your data is large enough, only separate columns have non-zero bytes in the end

RabidGravy eugh
cschwenz so, i am seeing "Cannot call AUTOGEN( […] ); non of these signatures match: […]" are you saying the "[…] AUTOGEN( […] ) […]" is the signature it was trying to find? 10:23
RabidGravy ah that old AUTOGEN thingy
cschwenz do i need to update/upgrade perl6?
psch doesn't know about any AUTOGEN thingies
RabidGravy if you add "proto method <name> (|c) { * }" you will get the right name 10:24
psch, under some circumstances it doesn't create the proto name right so it just leaves it as "AUTOGEN" 10:25
I've never figured out quite what those circumstances are sufficiently to RT IT
psch o.o
that sounds a bit bad
cschwenz: can you golf the code that gives you that error? 10:26
in case it stays around when golfed this might be an angle to try and figure out what's actually happening 10:27
cschwenz psch: probably
10:27 Actualeyes joined
RabidGravy it's something in the area of more than one multi with a certain number of candidates 10:28
cschwenz so, with that solved, next question… if i have multi-methods which take a single positional value, and said value has a default, why does "$obj.foo()" not do what i mean and use the default? (instead it complains about not finding a signature match) 10:29
psch m: class A { multi method f($ = "foo") { say "ok" }; }; A.f
camelia rakudo-moar 6cb231: OUTPUT«ok␤»
psch there most be more to that issue :) 10:30
RabidGravy I think I've encountered that one before too, can't remember the circumstances
10:30 zhmylove left
RabidGravy but yeah a golfed example of that one would be good 10:31
cschwenz p6: class Foo { multi method bar( Int $baz = 1 ) { say "Int $baz"; }; multi method bar( Rat $baz = Rat.new(1, 1) ) { say "Rat $baz"; }; }; my $obj = Foo.new(); $obj.bar(); 10:32

psch oh, that's easy. two candidates with one parameter with default are two candidates with 0 parameters
cschwenz hmm, that error message is different than the one i'm seeing
psch cschwenz: maybe you do have to upgrade your rakudo :)
cschwenz psch++ 10:33
10:33 zhmylove joined

psch tbrowder: PERL6LIB expects specs seperated by comma 10:51
a spec doesn't have to be a path, either

tbrowder psch: yes, or else tell me how to install them into the new rakudo build 10:56
psch tbrowder: RabidGravy++ recently published a module for exactly that 10:57
RabidGravy :)
robertle I have problems with understanding the very basics of modules as well: to get started I create a single module with a single sub with "is export" in it. I can use that module, and call the sub. great. but I am very confused about the namespacing: I seem to be only able to access exported stuff (which is ok), and the export puts it in the namespace of the loader. so the actual namespace of the sub does not
10:57 _28_ria left
robertle matter anymore. interestingly the "unit module xyz" at the top of my module does not need to match the path of it (also ok), so effectively the namespace does not matter at all! that can't be right, there must be more to it... 10:57
am I right in assuming that the "use" looks up by filename/path, so that does not have to match the namespace? 10:58
RabidGravy robertle, subs are "my" scoped by default, they aren't in a "namespace", if you want to refer to them with a full package name, qualify them with "our"
10:58 Actualeyes left
psch tbrowder: App::ModuleSnap, fyi 10:59
10:59 daniel-s left
RabidGravy but yes, the default behaviour of the repos is to derive the path from the module name supplied to "use" or "require" 10:59
of course a CompUnit::Repository could be made that does something else 11:00
robertle RabidGravy: right, so if I "need" then the contents of the file in question get loaded. if that's "our" then I can access it by namespace, if it is "my" then it's private to the namespace and inaccessible. if I use "use" instead, the loaded bits also are made availabel in the loading namespace, so no need to prefix anymore. that abut right? 11:01
RabidGravy for installed modules it is different again, as the name of the module isn't directly reflected in the installed module name
robertle, not quite
tbrowder psch: so how will App::ModuleSnap help me if I can't get it installed for the new rakudo? 11:02
robertle RabidGravy: right, the file vs namespace is a bit academic because you want them to match up anyway, everythign else is just plain confusing
psch tbrowder: i have no idea how it works, but i'd assume you install it for the old rakudo that already has the modules you need
11:02 Actualeyes joined
RabidGravy yes 11:02
psch tbrowder: RabidGravy probably appreciates any feedback re documentation or functionality :)
11:02 finanalyst left
RabidGravy it basically traverses the $*REPO.rep-chain, finding all the Distributions which aren't something it made or "CORE" and then writes out a META6.json with all those as dependencies 11:03
so in your other perl6 you do "panda install ." and voila
tbrowder psch: ah! okay, I'll give it a shot 11:04
I have to go now but will try it and report back--thanks!!
11:04 tbrowder left
RabidGravy because I seem to install a lot of modules for testing purposes I find myself with the need to completely eradicate everything once in a while and reinstall the modules 11:05
I've just discovered that "Flash Magic Eraser" is perfect for cleaning the white rubber parts of Converse All Stars, almost box fresh looking ;-) 11:08

RabidGravy is there something other than github "organizations" that people use for organising e.g. a "special interest group"? I'm thinking of starting a "Perl6 Audio" thingy 11:11
psch haha 11:12
DrForr SIGAUD, ISAGN.
psch special interest group made me laugh :)
RabidGravy :)
psch i don't think they have anything like that on github though
i'd totally join an org for that though, even if it might be somewhat inappropriate as an org on github vOv 11:13
11:13 ufobat joined
RabidGravy well an "organisation" gives you all the github stuff, wiki, issues and a github.io site but yeah it's not so much about the code as collecting and promoting the stuff 11:14
ufobat ola! :D just in case someone cares! my notebook is alive again
RabidGravy and of course becoming an evil and secretive cabal
psch right, but a github-page would be a good start for promoting i think
11:15 wamba left
RabidGravy so yeah, create a github organisation and create the page 11:15
psch i mean, unless you have an appropriate domain lying around... :)

RabidGravy jeezus-knievel.com? 11:16
perlmonkeys.org? plastic-fernandez.com, its-going-to-be-fabulous.com all unused but not really suitable ;-) 11:17
goatponi.es
psch its-going-to-be-fabulous.com is pretty close though
robertle RabidGravy: let me try again for "our" and "need" only. "our" stuff gets put in a namespace according to the enclosing "module". "need" loads a unit and therefore makes the namespaces within and what is "our" in them available. "my" stuff from the loaded unit is unavailable because it is lexically scoped, and the unit is the lexical scope. right? 11:18
RabidGravy yes, but "need" is a red herring here,
however you load it if the sub in a module isn't our scoped you can't access it at all outside the module 11:19
robertle RabidGravy: right, I said "need" only because "use" does something on top of it. let's check my "use" and "is export" understanding: "is export" or the more elaborate versions thereof takes whatever we are talking about and places it in a special namespace of the module. if you "use" a unit, everything from that special namespace makes it available in the loader. about right? if so: does use put into the t 11:22
RabidGravy m: module Foo { sub bar() { say "bar" }; our sub baz() { say "baz" };}; Foo::baz(); Foo::bar();
camelia rakudo-moar 6cb231: OUTPUT«baz␤Could not find symbol '&bar'␤ in block <unit> at /tmp/JljyT__jh2 line 1␤␤Actually thrown at:␤ in block <unit> at /tmp/JljyT__jh2 line 1␤␤»
robertle arget namespace or the target lexical scope?
psch "use" puts the used module into the current lexical scope, and imports all exported symbols into the current lexical scope 11:24
robertle RabidGravy: understood that part, but that's because bar() isn't part of the Foo namespace, just part of the lexical scope that happens to be created by the module/namespace block. rigt?
psch well, after (potentially compiling and) loading the source file
RabidGravy yes 11:25

psch and lexical scope is a namespace too /o\
robertle ok, great! somewhat off topic, but is there a way to "use" from a different namespace and put in this *namespace* rather than this lexical scope? there is such a concept in UML, and it is thoroughly confusing and interestingly impossiblt to implement in C++ and java, which makes you wonder why it is in UML in the first place...
psch robertle: i think reexportation could cover that at least partially, but i don't know in how far that's implemented 11:27
RabidGravy yeah, there are export tricks available
robertle psch: interesting! I don't really have any use for it, just wondering...
psch m: module Foo { use Test :EXPORT }; import Foo; 11:28

psch that's the speculated syntax, but yeah...
RabidGravy well at it's simplest you can define a "sub EXPORT" in your compilation unit which returns a hash that is keyed on the names you want to export with *what* as the value 11:29
and some <hand wave> other thing with the EXPORT package 11:30
psch m: module Foo { use Test; }; import Foo; ok 1 11:31
camelia rakudo-moar 6cb231: OUTPUT«5===SORRY!5=== Error while compiling /tmp/ExKc1N3mzA␤Undeclared routine:␤ ok used at line 1␤␤»

tbrowder psch & RabidGravy: I realize now (I think) if I want to hack on rakudo I should create my own branch and let rakudobrew manage it on my own machine. That way there shouldn't be any major problems with standard module handling. Am I right? 11:48
RabidGravy psch, having done a cursory survey of the alternatives I'm thinking that a github organisation is easiest and makes collaboration easier and chuck a custom domain on it later
psch tbrowder: uhh, for actual hacking on rakudo itself i at most branch rakudo inside its own repo 11:49
tbrowder: and build with Configure.pl
RabidGravy tbrowder, I've always used rakudobrew for day to day stuff then what psch said for hacking on rakudo
tbrowder but the problem with that has been finding modules
..installed modules 11:50
psch i don't think i ever needed modules to hack on the compiler
i'd suggest golfing the code module code that is buggy and writing tests from that
RabidGravy yeah I see it as two different enterprises
llfourn tbrowder: I just do panda --prefix=/path/to/forked_rakudo/lib if I want to install a module on non-rakudobrew rakudo 11:51
RabidGravy and when I really do need to do it I just use one or more -I<path to module> on checkouts of the modules
couple of times fixing breakage in my own or other modules from change in rakudo I do that 11:52
