kalkin- hi 00:05
is there a way to create an executable in perl6?
i heard it was possible to pack the moarvm and the perl6 bytecode together in one executable file, but i can not find a source for that anymore 00:06
sortiz skids, In that case I will try to make a PR with a case. 00:09

gfldex the offending commit for doc is github.com/perl6/doc/commit/a606c2...b548593411 00:34
however, the entire file look fine. It seams to be a problem with the pod-parser. 00:35
Ulti kalkin- I dont think there is anything that does it for you atm its "possible" but not implemented AFAIK, the JVM version of Rakudo can produce a JAR file though which might be portable
kalkin- Ulti: Ic, Thanks. 00:39
Ulti kalkin-: if you have the JVM backend you need a --target=jar 00:41

there's one on the north side too
grandkids are a little too young for those though
TEttinger there's the waterfall that IIRC the road stops at, I can't remember the circumstances but there's that coastal road that goes mostly around the island except... is it waimea canyon that prevents it from continuing> 02:49

TimToady no, it's Na Pali

ZoffixWin I mean, I can surmise it means how many cores to use, but I'm not 100% sure, which is not very friendly for docs aimed for programmer beginners 03:34

TimToady I suspect it's worker threads, which might or might map to cores, depending 03:35

llfourn ah yeah you're right. 03:53
is the above behaviour just a special feature of postcircumfix? :foo turns into a positional? 03:54
so you have adverbs to get around that...

Herby_ is there a json reader that comes with Task::Star?

Herby_, IIRC JSON module included with it isn't one I like to use. I prefer JSON::Fast 03:56
skids llfourn: It is defined basically the same for postfix:<{ }>, but then there is some crazy code for optimizing combinations of adverbs so it may be trickier there.

llfourn skids: but the general idea is that passing { :foo } is not the same as somesub(:foo) so you have adverb syntax to be able to pass named in these cases? 03:58
ZoffixWin llfourn, I don't really see how you infer that :foo would be *inside* the curlies in that case

arnsholt sortiz: Don't think it's the REPR. Given that adding the explicit is Any works, looks more like it's the supertype 10:12
moritz the problem is using a constraint type before the type is composed, no? 10:13
arnsholt jnthn: Presumably the implicit inheritance from Any is added only on the closing brace if no inheritance is specified?

can i specify multiple return values / types / containers? ie can i statically specify "Returns a tuple of Records and RecCount" or whatever?

hahainternet gfldex: it's the two different types inside the same list or similar that i'm interested in specifying, fwiw :) 11:20
gfldex hahainternet: note that this is just a type check. It wont check any containers inside the array
hahainternet oh really? I thought you could do something like Array[Int] to specify, i'm not too up on static typing in p6 11:21
gfldex there is no static typing in Perl 6
hahainternet that is a purely semantic argument
11:22 gregf_ joined
gfldex static typing happens at compile time, dynamic typing happens at runtime 11:22
i can't see where you see semantics in that
moritz Perl 6 does typing at compile time 11:23
m: sub f(Int) { }; f 'sadf'
camelia rakudo-moar d67cb0: OUTPUT«5===SORRY!5=== Error while compiling /tmp/EFl8fD4vuq␤Calling f(Str) will never work with declared signature (Int)␤at /tmp/EFl8fD4vuq:1␤------> 3sub f(Int) { }; 7⏏5f 'sadf'␤»
moritz this is compile time, for example
hahainternet 'static typing' typically refers to the ability to restrict the type of a container specifically too
not the 'time' at which the restriction is applied
moritz also, role composition and the associated checks happen at compile time
hahainternet even if what moritz showed only worked at runtime, that's still much closer to static typing than dynamic
11:24 vendethiel joined

technically, that's not at compile time, but it is before INIT time :-)

hahainternet oh, so perl6 doesn't have 'tuples' lol
just lists and the like
lizmat so far, I have covered all blog posts and ecosystem updates, FOSDEM, IRC channel additions 11:42
timotimo yeah, but lists are already read-only (unless you bind scalars in)
hahainternet timotimo: it's more the ability to specify that element 0 is type X and 1 is type Y i was interested in
11:43 moritz joined
timotimo oh 11:44
fair enough
lizmat moritz++ # irclog.perlgeek.de is back
hahainternet i believe you can restrict the containers, but i'm not aware of the underlying mechanisms, so all i know of is the usual Array of Whatever type stuff

11:46 vendethiel left, virtualsue left
gfldex that doesn't check for excess elements tho 11:46
hahainternet indeed, where clauses are certainly sufficient 11:47
it's not a problem i'm facing in any real code
it just came after some discussion about code in haskell with a friend 11:48
gfldex return type checks do not contribute to MMD, where in heskell they do. In Perl 6 return type checks can keep errors local and that's pretty much it. 11:49
hahainternet well i don't expect perl6 to be as strict as haskell :) 11:51

nanis When I clone from rakudo/rakudo, and run perl Configure.pl --gen-moar ..., what determines which MoarVM and nqp snapshots I am going to get? What do I need to do if I just want the tip? 12:39
Skarsnik the tip? 12:40
RabidGravy HEAD 12:41
nanis Yes, I meant HEAD.
It's still early for me.
Is specifying --gen-moar=master the right thing? 12:42
RabidGravy I think that it gets at *least* the version specified
12:42 kid51 left
Skarsnik --build-moar=master probably 12:43
moritz if you leave out the version, it takes the NQP version from tools/bulid/NQP_REVISION
and the NQP repo then has a similar file that specifies the default MoarVM version
so if you just perl Configure.pl --gen-moar, you get the recommended versions
nanis moritz: Thanks for the explanation. 12:44

Skarsnik is there something to display number in a nice way? like with 52463 -> 52.463 ? 12:50
AlexDaniel Skarsnik: /1000 ?
Skarsnik: and printf 12:51
DrForr '.' isn't necessarily a decimal separator, I think that's what Skarsnik is after.
AlexDaniel oh
nanis AlexDaniel: What to do with 1000000?
AlexDaniel right, ok 12:52
DrForr (living in a country where the decimal separator is ', ' or "'", and months are in Roman numerals sensitizes you to such things :)
AlexDaniel DrForr: roman numerals are fine. At least it's not some random made up names that don't make any sense 12:53
Skarsnik: it sounds like a great idea for a module
Skarsnik: or perhaps you can manage to get that into printf, hmm… 12:54

Promoted means "objects survived two garbage collection runs" 14:18
Skarsnik I don't know how to read that. there 15 'runs' on 70 that get promoted stuff 14:19

Skarsnik imgur.com/Fga4ZQU 14:23
jnthn In short: if objects that reference large native data structures are promoted into the long-life pool, then the amount of memory the GC sees as being promoted is relatively small, but they may be holding onto large amounts of native memory.
Skarsnik gah I cut the first ><
jnthn Wow, lot of green. :) 14:24

nanis Happy to report that the problems I was having earlier with native call tests were being caused by an errant -Gy "separate functions for linker" in %CFLAGS% in my environment. With that removed, all native call tests pass.
anthk_ jnthn: $fh.seek() ? 14:41

jnthn anthk_: yes
AlexDaniel ZoffixWin: ah dammit! That's what the first comment says! 14:42
anthk_ Cannot call seek(IO::Handle: Int, Int); none of these signatures match: 14:43
ely-se does NativeCall support volatile?
jnthn anthk_: Yes, I gave you a link to the docs showing how you have to call it above 14:44
14:44 go|dfish joined
ely-se It seems not. :/ In that case how can I distribute C code with a Perl 6 module? 14:45
Skarsnik nanis, nice
volatile? 14:46
RabidGravy ely-se see LibraryMake in the first instance
Skarsnik is that not a c++ stuff?
RabidGravy there are a few examples of modules that do it in the ecosystem
jnthn ely-se: A volatile what, ooc?
ely-se jnthn: equivalent of extern int volatile *p; *p = 0; 14:47
jnthn Ah, on a global
I don't think our optimizer is smart enough to not make every read an actual read yet anyway on those :) 14:48
Skarsnik why would you want to use volatite?
ely-se jnthn: ok :p 14:49
leont There are very few cases where volatile is something you want or need
In general, it does something different from what many people assume
jnthn Not to mention it does different things in different languages. :) 14:50
dalek c: f2972d8 | (Wenzel P. P. Peppmeyer)++ | doc/Type/Callable.pod:
more build fixing
leont That too
jnthn iirc, it's really not strongly defined in C
ely-se jnthn: and in different compilers for the same language
14:50 regreg joined
leont C++11 pretty much deprecated it in favor of atomic loads/saves with explicit memory ordering 14:51
ely-se MSVC guarantees reads and writes from and to volatiles are atomic (lol)
leont: what? no. volatile never had anything to do with atomic loads and stores, and C++ never deprecated it
leont I know, it's the explicit memory ordering that's replacing the volatile
jnthn The C# definition is acquire/release semantics, and so prevents certain re-orderings.
Which is kinda useful. 14:52
leont en.cppreference.com/w/cpp/atomic/memory_order
It's just that you can't really do any sensible memory ordering without it being atomic
ely-se I want to use volatile and clearing to make it less likely passwords end up in crash dumps, and mlock to make them not go to swap 14:53

Skarsnik jnthn, it leaks/grow a bit more now xD 14:55

leont ely-se: why would volatile help there?
anthk_ it's inside a for loop, I don't know, if I open the file, I understand it would beggin to seek from the byte 0 by default 14:58

anthk_ RabidGravy: that could work? 15:03
moritz don't we have a .recv method or so that provides the data in batches as they come in? 15:05

RabidGravy does anyone know of a list of media types that can safely be considered "text" for the purposes of decoding? e.g. "application/xml" , "application/javascript" etc 15:16

chacewells ic 16:56
AlexDaniel chacewells: also note that this way we are not working with shell, so all shell problems are gone
chacewells: that being said you can still change ｢run｣ to ｢shell｣ and it will work too
though you obviously can't pass separate args this way to shell, so you just smash it into one vulnerable string :) 16:57
e.g. shell(‘echo hello world’)
but :out and :in should work exactly the same way
chacewells so great. OO, yet concise 16:58
AlexDaniel chacewells: one thing that is not so concise is when you want to slurp everything into a variable. In that case it is ｢my $x = run(…, :out).out.slurp-rest;｣ 16:59
chacewells: so you specify that you want the output. then you get it and then you slurp everything from it. Sure enough it makes sense, but it is a bit painful to type :) 17:00

Technaton Okay, neither JSON::Tiny nor JSON::Fast can actually parse the 82M JSON dump. :( Argh, and I though that calculating the eucledean distance of a number of vectors would be a nice opportunity to try Perl6… Well, something else will come up. :) 17:29

AlexDaniel Technaton: what about Inline::Ruby solution above? 17:31

Technaton That feels awfully like cheating. ;-)
AlexDaniel but you can still be comfortably using Perl 6 as a glue
moritz Technaton: cheating is technique 17:32
alpha123 Technaton: I prefer "borrowing existing implementations"
ilmari alpha123: "leveraging" 17:33
alpha123 ah yes, that's the word i was looking for
good artists reimplement, great artists leverage existing solutions
Technaton Uuuuh. Okay, marketing did its job wonderfully, I'll try using Ruby's parser. 17:34
jdv79 Technaton: maybe someday that will work; hopefully
17:34 yqt joined
alpha123 Technaton: Rakudo is not particularly fast at the moment. Sorry :((( 17:34
autarch when I write "my %foo = @bar" what is actually happening under the hood? is this a coercion? how does p6 know how to coerce an array to a hash? 17:35
AlexDaniel Technaton: well, actually it is not so much about cheating, it is more about glueing
Technaton alpha123: I don't expect miracles, no worries. And I want to try a new language that has just seen its Christmas release, so... Who am I to complain?
AlexDaniel Technaton: NativeCall and Inline::* are very useful tools :)
Technaton I'll keep that in mind, thanks. 17:36
alpha123 autarch: well %foo is a hash and @bar is an array so it does what you tell it to....
Technaton I was just worried about the RAM consumption. I left Rakudo with JSON::Tiny to work on my JSON file and went to eat something, and when I came back, the OOM killer had terminated it. So I naturally thought I did something very, very wrong.
jnthn autarch: It calls %foo.STORE(@bar). STORE iterates @bar. If it sees a Pair object it uses its key/value properties. Otherwise, it just uses things as keys and values in turn 17:37

alpha123 Technaton: that doesn't seem quite right 17:37

pmurias creating Perl 6 hashes in NativeCall'ed C code is not supported by design? 17:38

Technaton AlexDaniel, alpha123: FYI, using Ruby's JSON parser worked like a charm. Thanks!
jdv79 i think there are plenty to link up with pmurias:) 17:40
AlexDaniel OK on the similar topic: is there anything that will do the job of HTML::Parser::XML but faster? 17:41
it doesn't eat 16 gigs of ram but it takes about 15 seconds to parse a page – not good enough in my particular task
17:41 _mg_ left
jdv79 I::P5 + those modules (HTML::Builder, TokeParser, etc...) ? 17:41
AlexDaniel any recommendations? Some perl or ruby module?
pmurias jdv79: the hard part would be to minimalize the NativeCall overhead 17:42
AlexDaniel I don't have to generate HTML, just parse it 17:43
jdv79 isn't it just "here's a json text. give me back a p6 structure"? how does that have high NC overhead?

autarch I'm giving a short talk on p6 tomorrow night at my local Perl Mongers - I'd appreciate some feedback on my presentation 19:26
if you check out github.com/autarch/presentations and then go into perl6-for-mpm you can see it 19:27
ely-se masak: seems to be a problem with recursive multis
autarch you can just open the index.html in your browser and it should work - if you wanted to also see the speaker notes you'd need to run "grunt serve" and then hit "s" in the browser when it opens the presentation
ZoffixW That's a lot of talks you got there :D 19:28
autarch I'm mostly interested in feedback about whether things are actually correct, not adding more content, since the goal is 20-30 minutes and I'm sure there will be lots of questions

awwaiid broken symlinks :)
[Coke] Do I need to put this behind a web server?
awwaiid ../reveal.js is empty 19:34
[Coke] ah
jnthn autarch: Yes, but making things OO that don't need to be may also put some people off. :-)
autarch [Coke]: git submodule update in the top level dir, I suspect 19:35

AlexDaniel autarch: what's the easiest way to render that thing 19:45
autarch: ?
autarch AlexDaniel: if you check out the repo, then "git submodule update --init", then open the index.html, it should be visible
ZoffixW AlexDaniel, git submodule update --init; then just open it with your browser
AlexDaniel autarch: it seems like it requires reveal.js but there's no…
oh ok
ZoffixW autarch++ read it all. Looks good to me :)
AlexDaniel autarch: so it requires your public key in order to do that… 19:46
I mean, not just the public key
autarch doh, let me fix that
AlexDaniel because it is trying to clone from [email@hidden.address] 19:47
hmm interesting… why would that be a problem?
ZoffixW You know what would be cool? A way to say "await" for all promises in the current scope.
autarch AlexDaniel: fixed 19:48
jnthn ZoffixW: await gather { ... take all the promises } :-)
ZoffixW still needs to learn what gather/take are all about 19:49
AlexDaniel ZoffixW: interestingly I've asked that question about a year ago
or maybe more
autarch: thanks, it works now 19:50
PerlJam ZoffixW: without the gather/take syntax it sounds like you just asked for action-at-a-distance
[Coke] autarch++ 19:51
AlexDaniel autarch: why build 2015.12 ?
autarch: instead of the latest
ZoffixW PerlJam, not too much distance. Say, running a bunch of fire-and-forget code, and just waiting for them to complete at the end of the block

19:54 musiKk joined
AlexDaniel autarch: about “counting words” example, is it supposed to be 1 to 1 port? 19:55
autarch: because there are ways to make it much shorter in perl 6
jnthn ely-se: No, though why would you wish to?
ZoffixW m: sub do-things { await gather { take Promise.in(2).then: { say "42"} } }; say "meow";
camelia rakudo-moar d67cb0: OUTPUT«meow␤»
jnthn ely-se: It only caches based on type, never on constraints.
autarch AlexDaniel: I copied the build instructions from perl6.org 19:56
AlexDaniel: not really supposed to be 1-to-1 port, though if the shorter version is more like a golf version I don't think I'd want to use that - what were you thinking of specifically?
jnthn (And of course "no" as in "there's no API for it 'cus it's purely an optimization" - if you're willing to null out the thingy where the cache is stored then you can...
...excpet the VM will have inlined based on the cache too perhaps.) 19:57
ely-se jnthn: for debugging
there seems to be a problem with recursive multis 19:58
jnthn Well, you can set MVM_SPESH_DISABLE=1 to rule out the VM's own opts 20:01
(rule them out if it makes no difference, that is)
ely-se jup, problem persists 20:02
the program crashes 100ms faster with that environment variable, though :) 20:03
Skarsnik huhu
20:03 konobi_ is now known as konobi
AlexDaniel autarch: First thing was that I thought List.unique was able to produce a hash with counts (exactly what is required). But it doesn't, such a pity. 20:04
autarch: then, the first loop can be written with ｢for｣ on right hand side
autarch jnthn: btw, did you see the slide about the perl6 stack? I wasn't sure if I described that correctly - it's slide 16
AlexDaniel autarch: otherwise it is kinda weird, why write the second one in such fashion but not the first one? it is other way round :)
autarch: because I find the second one a bit hard to read because of that. But that's just a style question, so whatever. 20:05
autarch AlexDaniel: what is first & second in this sentence?
AlexDaniel autarch: for loops
autarch: in “counting words” example
autarch oh, I see postfix vs prefix
AlexDaniel autarch: in perl 5 version it was required because it had ｢chomp｣ 20:06
autarch right
yeah, in that case I was just copying the program structure between 5 & 6
AlexDaniel but indeed it's such a pity that List.unique can't give you the count right away 20:07
unique even has :as(&lc) trick which is required in this example 20:08
20:12 chacewells left
AlexDaniel autarch: sort(&[<=>]) or sort(* <=> *) is perhaps more readable than sort({ $^a <=> $^b }) 20:12
autarch: but again, it's not an issue. Great presentation 20:13
timotimo oh, a presentation?
ah, there it is
ZoffixW autarch, if you want some pedantism: lc is not a good thing to use for caseless comparison. Perl 6 has .fc method and Perl 5 has fc function for that.
timotimo hm. what should i do to watch this? 20:14
AlexDaniel timotimo: git clone it
20:14 roguelazer left
Skarsnik fc? 20:14
ZoffixW timotimo, git submodule update --init; then just open it with your browser 20:15
Skarsnik, "fold case"
huggable, Str
huggable ZoffixW, class Str [String of characters]: doc.perl6.org/type/Str
AlexDaniel autarch: also, as a Perl 5 programmer I'd probably like to see ｢.say for $foo.values;｣ instead of ｢say $_ for $foo.values;｣
20:15 ruoso left

ZoffixW autarch, ^ use a Bag instead of the hash (or checkout other Bag/Set types)
Then your first loop just becomes my $words = Bag.new: $file.IO.open.words; 20:17
(i.e. no loop needed)
AlexDaniel oh!! Bag!!
there it is! Yes!
jnthn autarch: I didn't see anything in there that concerned me.
(about the stack)
AlexDaniel ZoffixW++ for remembering Bag! 20:18
ZoffixW In the Bag, I also see classify-list and categorize-list methods that sounds interesting, but aren't documented :D
I wonder if they can be used in lue of the sorting loop

ZoffixW Yeah, the talk is fine the way it is... We're just thinking aloud here :)
jnthn ely-se: That won't dispatch to either since you're not passing a List?
ely-se refresh :P 20:22
musiKk can anybody offer a mnemonic for rule vs. token? I always forget which one has sigspace.

ZoffixW musiKk, rule => raw (i.e. you get whitespace and all)

AlexDaniel ZoffixW: and classify-list does something similar
ely-se jnthn: ok
jnthn ely-se: multi term-expr(List:D $datum where *[0] eqv 'do') { say 'correct' } # it always runs this one for me
AlexDaniel ZoffixW: github.com/rakudo/rakudo/blob/nom/...gy.pm#L517
ely-se jnthn: yeah my code is a little more contrived but thanks for confirming
it's hard to make a reproducable example for this 20:25
jnthn musiKk: Tokenizing is traditionally about breaking things up into tokens, that is the "atoms" 20:26
musiKk: But I guess that only works for those of us with enough of a compiler-y background :)
ZoffixW musiKk, tokens make me think of subway tokens... no sig space around them :)

oooh, an Inline::Scheme with pluggable backends onto multiple r5rs interps would be ace
DrForr Guile was the first one I ran across that seemed reasonably commonplace. 21:18
mst racket is, to my mind, more so (used to be drscheme)
moritz oh, I learned some scheme with drscheme 21:19
mst and in fact I stopped even pretending to plan to maintain perl5's Guile bindings when I realised audrey had written mzscheme mindings
DrForr Ah, I've worked with that when it ws drscheme.
mst guile's not a bad choice, but mzscheme/racket is IMO a better scheme
moritz we had an optional CS course in $schooll that was worth its name, learned a bit of scheme there. That was fun
mst of course, my exact memories on this are buried in the mists of years ago
awwaiid Cool DrForr. I'm hoping that we can extract some comonalities between these Inline:: langs (and rename the namespace while we're at it); I'll take a look at Inline::Scheme to see what overlap we have 21:20
21:20 jernster is now known as jme`
autarch doc.perl6.org/ and doc.perl6.org/ appear to have different styles 21:20
nine awwaiid: go go go :)
awwaiid nine: I got Inline::Ruby broken out into some separate files and bashed travis-ci into submission finally 21:21
PerlJam wonders when we'll get Inline::COBOL and Inline::Fortran ;-)
awwaiid nine: sometime I'll see if I can get Inline::Perl5 on travis
DrForr awwaiid: It's pretty simplistic at this stage, it'll be more complex/useful once I figure out how to portably crack an SCM type object open.
awwaiid in theory I'm at $work right now though
revhippie autarch: woah, strange. 21:22
autarch yep
21:23 nowan left
alpha123 Inline::Fortran would be pretty useful 21:23
autarch aha, chrome is blocking the load of one of the sheets because it has an explicit http:// url
probably best to make all sites canonize to https or http
awwaiid it's actually the ecosystems that I want to get ahold of more than the langs :)
21:24 Psyche^_ joined
moritz autarch: or just link to protocol-relative URLs 21:24
ugexe to test Inline::Perl5 on travis just use `perl: '5.20-shrplib'`
autarch no point in serving the site from both http & https, is there?
moritz yes: choice
also, I'm pretty new to the whole running-as-https thiing
flussence lazy fix would be to throw a "Content-Security-Policy: upgrade-insecure-requests" header in there and let the browser figure it out :) 21:25
awwaiid ugexe: yes. and to test ruby I just added 'rvm install ruby-2.3'. But... subtle issues esp around linking haunted me. I hope it'll be that easy.
moritz autarch: what's the offending resource?
21:25 Psyche^ left
alpha123 autarch: //url.com works uses http: or https: depending on the current url, so you don't need to bother canonicalizing them 21:25
autarch moritz: design.perl6.org/perl.css 21:26
ugexe i've installed Inline::Perl5 on travis and test it. there were no issues luckily

dalek ar/release: 1225071 | FROGGS++ | tools/build/Makefile.in:
fix thinko when invoking panda

Running "perl6 panda-m.bat" certainly wont work on windows. Though
  "perl6 panda-m" will.
moritz off topic: does anybody know some tool to help fat-package a perl binary and all perl dependencies into a Debian package?
21:30 geraud joined
Skarsnik dh_make? 21:30
Oh a fat package
21:30 jpoehls_ joined
Skarsnik I don't know 21:30
moritz Skarsnik: I was thinking more magical, like dh-virtualenv for python
FROGGS moritz: I just know about staticperl, which packs all the things into a binary 21:32
mst moritz: build local::lib. tar up results. feed tarball into fpm?
ajr_ mst: In almost all shell scripts, I validate the command line arguments, (#, types, and values) first, then start the actual operations. MAIN looked as though it would do some of that automatically and provide a place to do the rest of the validation, but it feels wrong to put the rest of the code in there. but 21:33
21:33 abaugher_ left, yurivish_ joined
mst ajr_: well, if you're using MAIN, that's where the code belongs 21:33
that's like the whole point of it 21:34
provide an entrypoint for the main code of the script
that can do argument validation etc. for you
21:34 autarch left
mst if you define MAIN, it's basically equivalent to having 21:34
moritz ajr_: Perl 6 isn't shell scripting. Get over it :-)
21:34 abaugher_ joined
mst run_arg_parser_and_call(MAIN); 21:34
at the bottom of the script
ajr_: and I'm sure you've seen shell scripts that end 'main;'
moritz: yes, that's a much kinder and constructive thing to say to a confused newbie than my explanation :P 21:35
jnthn YOu can also do `unit sub MAIN($a, $b);`
Which will make the rest of the program body be considered the implementation of that sub.
Which shaves a level of indentation
Uh, saves 21:36

remove WIP patch files
RabidGravy hacks deflate/gzip handling into H::UA 21:39
Skarsnik hm, how? 21:40
RabidGravy using Compress::Zlib, works really nicely
ajr_ mst: (16:34) Can't say that I have, but I haven't read many others, except for the system stuff.
Hotkeys used on its own what is the difference between given and with
jnthn with only runs the code if the value is defined 21:41
mst ajr_: well, it's pretty common tbh
Hotkeys ah
jnthn There's a without for the other case
mst ajr_: but, yeah, as jnthn said, if you don't want the indenting
Skarsnik RabidGravy, is not perl6 native?
mst unit sub MAIN (...);
<now inside MAIN until eof>
is totally supported
RabidGravy Skarsnik, que? 21:42
mst and if you find it more comfortable, go ahead and use it
Skarsnik C:Z is written in perl6 or it's NC code? x)
ajr_ Running an entire program inside a subroutine just feels wrong.
RabidGravy Oh native call
mst ajr_: everything is always doing that
ajr_: it's just some things provide an implicit magical top-level subroutine for the file
ajr_: really 21:43
dalek kudo/2016.01-preparation: 74dd4e2 | FROGGS++ | src/core/CompUnit/Repository/ (2 files):
make CUR.bindir overridable

This is useful when several CURs share a single bin directory on disk. Also when we have repositories that keep the distribution data on a non-local storage, we need to keep the wrapper scripts in a local bindir, so that these can be in PATH. Rakudo Star will be the first user of this funtionality.
mst ajr_: and because shell does it taht way, you don't see the main subroutine
21:43 sevvie joined
RabidGravy but I've made it optional. It just craps out if it isn't installed and the body needs inflating 21:43
mst ajr_: but conceptually it's totally there
moritz ajr_: on the contrary, it's best practice; makes testing easier for example
mspo isn't pretty mucb every lanaguage structured like that?
moritz python folks do it all the time
21:43 dotness joined
mst mspo: um. no. C uses main(), java uses main(), lots of things use main() 21:44
21:44 dotness left
mst perl6 lets you use MAIN if you want to, and not if you don't 21:44
but if you decide to avoid MAIN, you don't get the features of MAIN
mspo so lower level languages have you explicitly type it
RabidGravy I think it's a nice compromise 21:45
21:45 maslan left
moritz travis-ci.org/perl6/Pod-To-HTML/bu.../104747418 can anybody make sense of this? 21:45
mst ajr_: so, yeah, it only feels weird because you've missed all the other languages that do do it that way, and it's ok :)
also it makes it way easier to write tests for things
if the 'body' of the script isn't in an implicit top level sub 21:46
you can load it and poke it with a stick
moritz ah, do we have to add /home/travis/.rakudobrew/moar-nom/install/share/perl6/site/bin to $PATH in the travis.yml?
mst so basically all my shell scripts and perl5 scripts have a main anyway
it's a pretty standard convention for anybody writing production scripting stuff
(common in Tcl as well, and in python)
Skarsnik RabidGravy, a nice thing will be a full perl6 zip support x) 21:47
RabidGravy and if you want to do something different you can make it easier (by inserting a MAIN or otherwise capturing control at that point)
ajr_ I'm familiar with C's main, but I think it's the "subroutine" part that's causing the cognitive dissonanance.
RabidGravy Skarsnik, carry on I won't be stopping you :) 21:48
Skarsnik x)
I am surprise it did not exist
moritz ajr_: you can still call other routines, making MAIN only a *SUB*set of all the routines in there
Skarsnik *suprised
21:48 dfcarpenterak joined
mspo C's main is a subroutine? 21:48
RabidGravy well a function
in C parlance
moritz it's just nomenclature
alpha123 perl subroutine == c function
mspo they're all just objects ot C, right? :) 21:49
Skarsnik main is just a symbol
int main; is a valid C program x)
ajr_ This discussion may have cleared up a question about the Test modules. It was clear how they worked for subroutines and modules, but testing whole programs seemed to need another step up.
21:49 colomon left
mspo is 'main' special in asm? 21:49
alpha123 mspo: that's up to your assembler 21:50
Skarsnik Na, but the kernel search for a main symbol
moritz ajr_: a nice trick is to a a multi sub MAIN('test') { use Test; test code here; }
masak hm, I wonder how close a JS-like "transpiler" approach might be able to push Perl 5 towards Perl 6...
maybe that won't actually be much more powerful than what can already be done with source filters and parser hooks 21:51
DrForr Solved the core of the typing issue, will do an improved version tomorrow with any luck.
moritz masak: afaict there are two approaches; one generates readable but often wrong code, and the other generates unreadable code with lots of supporting libs
DrForr Most assuredly my ToPerl6 converter does the former :) 21:52
G'nite.
masak moritz: are you talking about compile-to-JS languages in particular? because IMO TypeScript generates readable *and* correct code most of the time
RabidGravy toodles
moritz masak: no, about 5-to-6 or 6-to-5 transpilers 21:53
RabidGravy but aren't TypeScript, CoffeeScript et al *designed* to be "transpiled" to Javascript?
don't have that luxury with 5-to-6 21:54
diakopter I think the word transpile is meant to imply 'readably compile'
konobi coffeescript is a shitshow
arnsholt My suspicion for P5 on P6 is that the P5 lexer and parser stages need to be compiled to Perl 6 code (custom flex and yacc compilers, possibly? But what about the action code, in C, which is the meat of it?) and then the rest of the runtime can be implemented on top of that
masak note that I wasn't saying "compiler Perl 6 to Perl 5"
I was saying "try to push Perl 5 closer to Perl 6 by compiling a language to it" 21:55
diakopter how does that push...
konobi probably better as a tool to inspect the AST and suggest changes 21:56
masak I dunno. all I know is that TypeScript pushes JavaScript closer to being a static language.
konobi yeah, with some side effects
arnsholt Oh, right. Now I see what you mean, masak. Never mind my gibberings 21:57
I'm not sure what it would look like, but it does sound like an intriguing idea 21:58

jdv79 or i'm misunderstanding
i rm -rf'ed my preview rakudo checkout and cloned fresh and built 22:05
