chee i notice node.js's http library can listen on a unix socket, does anyone know if there's any such module for perl 6? 08:17
jmerelo chee: you mean, as part of the standard library?
tadzik Cro::HTTP is the cool thing these days and it can be an HTTP server 08:18
08:18 qiqi joined
jmerelo chee: there are many HTTP-listening modules in Perl 6, including, as tadzik says, Cro::HTTP 08:18
holyghost a search for sockets and networking should get you to the docs of it 08:19
08:19 netrino_ joined
holyghost There's a CATCH based client-server system somewhere in the perl6 docs 08:19
08:20 Kaiepi left
chee jmerelo: i did check cro, but the only mention i saw of sockets was about websockets 08:21
08:21 DarthGandalf left
chee sorry, that was meant for holyghost 08:21
or everyone really
tadzik chee: doc.perl6.org/type/IO::Socket::INET those are the regular sockets 08:22
that's just raw TCP thoughu :)
holyghost chee : it's not cro, what I meant, but tadzik's link should help out
use IO::Socket; etc 08:23
chee yeah ^.^, i'm wondering if there's an http module that will listen on an IO::Socket rather than an ip and port
oh
doc.perl6.org/type/IO::Socket::Async
sorry, i was unclear earlier. i meant a socket file 08:24
holyghost in C, fileno(int socket) you mean ?
*lol* I mean socket, int fileno(FILE *) 08:25
tadzik ooh, a unix socket, I missed that earlier in a conversatino 08:27
sorry, everything I said was wrong then :P
I don't think there's anything for that, except for using NativeCall or maybe Inline::Perl5 08:28
chee ahh, okay. is there no unix domain socket support at all in p6? 08:31
tadzik not that I know of, no :(
on the plus side, you're in a prime position to make history by implementing it ;) 08:32

Kaiepi .tell lizmat your code looks pretty straightforward but what's the purpose of $!low-mark and $!high-mark? 09:28
yoleaux Kaiepi: I'll pass your message to lizmat.
lizmat high-mark is an indication of the maximum number of values that will be buffered 09:29
yoleaux 09:28Z <Kaiepi> lizmat: your code looks pretty straightforward but what's the purpose of $!low-mark and $!high-mark?
09:29 netrino_ left
lizmat and low-mark is the number of elements in the buffer at which it will start filling again 09:30
the values are pretty arbitrary at the moment
it possibly makes sense to increase the high-mark to 1000 09:31
to avoid small size lists to avoid the parallelization overhead 09:32
Kaiepi why are they needed?
lizmat well.. the high-mark tries to adapt itself to an optimum size 09:33
if the load on the mapping is too low, it will raise the high-mark 09:34
if the load is too high, it will decrease the high-mark 09:35
09:35 netrino_ joined
lizmat Kaiepi: in an earlier version, I found that the reader would be reading values faster from the buffer than the writer could add them 09:39
so that's why the initial buffer filling
Kaiepi ahhh 09:41
ok
would using something like a semaphore work? 09:45
jnthn I think what we really miss is a way to make a Channel have a bound 09:48
09:48 mowcat left
jnthn So that pushing something into it can also block 09:48
Kaiepi in go you can create channels with a buffer length 09:53
if the number of values on the queue is equal to the buffer length, pushing blocks
jnthn Yes, same in Java, C 09:55
*C#, etc.
Something for us to have too, just nobody got around to it yet :)
Well, they did, but in the ecosystem... :)
And less efficiently than if we just support it "natively"
Kaiepi lizmat, there's one problem with your implementation 10:02
it assumes $source is a list of some sort when that's not always the case as used in the ecosystem 10:03
m: sub base36(Int $num --> Str) { $num.base: 36 }; say do { 35 ==> base36() } 10:04

yoleaux 06:28Z <jmerelo> sena_kun: I'm back
timotimo sena_kun: maybe "The"? 12:43
sena_kun ah, yes, or this one
sena_kun tries to be better with articles, but has a long way ahead 12:44
jast I would keep it as it is 12:46
to keep with the standard form of the "obligatory X" meme 12:47
timotimo put in some extra stuff at the end 12:48
12:49 mowcat joined
jast "The request was actually just to allow configuring only [...]" is a bit of a bumpy read 12:50
same paragraph: "complicated" has a negative connotation, maybe "detailed" or "in-depth" 12:51
timotimo refresh for different colors at the end
jast "While deciding upon what exactly I should build" - not a complete sentence 12:52
timotimo refresh, i reworded it
ah, yes
jast yeah, I like that better now
timotimo have a look at the new start of that paragraph 12:53
jast yeah, nice 12:54
structural thing: after the first example program, you describe frame vs sf. this is a little hard to follow because at that point you have seen sf but not frame in the example, yet you talk about frame first. if the syntax/meaning allows for it, I'd include both frame and sf in the example somehow, so that you can see both in action, making it easier to understand an explanation of how the two relate 12:55
timotimo sadly, frame can't go in this example
jast yeah, I had an inkling that it might not 12:56
you could either make it two examples, or skip over explaining 'frame' here and just focus on what 'static' means in this context
I mean, once I finish reading the paragraph I understand it all, but in the middle I'm a bit "???" 12:57
or you could explain the 'entry' line first, giving more context about this, before explaining frame vs sf 12:58
timotimo that's valuable input, i'll see if i can reword it
the thing with putting entry first that made me want to put it at the end instead is the big list of possible entry points i have below
jast which would make it mostly about re-ordering a few paragraphs
13:00 netrino_ left
timotimo something's wrong with the font in the examples at the bottom 13:00
things just don't line up ...
jast how about something roughly like this... the 'entry' decides which stage of profiling the program is applied to. in this case, the 'profiler_static' means we're seeing a routine for the first time, before we enter any specific frame, so [...]. [...] these are the other types of entry points:
13:01 veesh left
timotimo perhaps the font it's using is missing a few of the glyphs and is falling back to another one for those 13:01
13:01 veesh joined
timotimo yeah i like that suggestion 13:01
I'll give it a try after i defeat the font rendering at the bottom 13:02
jast font woes, sounds like fun

lizmat did that, didn't solve the problem
timotimo damnit
wanna try figuring it out together? 13:37
lizmat sure
I got a checkout of Terminal::Print locally
perl6 lib/Terminal/Print/Commands.pm6
timotimo when i run that i get a bunch of messages from 'tput: unknown terminal "xterm-kitty"' and the same for "rxvt-unicode-256color" 13:38
lizmat gives me a long list of: gist.github.com/lizmat/a966bc3b1de...215359f3f7
indeed
$ perl6 lib/Terminal/Print.pm6 13:39
===SORRY!===
Please update @valid-terminals with your desired TERM ('xterm-color', is it?) and submit a PR if it works
set | grep TERM
TERM=xterm-color
timotimo OK, when i add that it gives the exact same output, so it seems to find xterm-color just fine on my machine as well 13:40
lizmat added that to @valid-terminals
and get the ===SORRY!=== again on running lib/Terminal/Print.pm6 13:41

lizmat when I run it as "perl6 lib/Terminal/Print.pm6" there is no precomp involved ?? 13:42

nadim_ hi, is it possible to get more info when one gets messages like "Cannot find method 'ann' on object of type NQPMu", a file and line? 15:15
jmerelo nadim_ there's a DEBUG environment variable you can use. It might be a bit too verbose. 15:16
timotimo huh? i haven't heard of that 15:17
nadim_ hehe!
just DEBUG=1 perl6 ...?
timotimo usually --ll-exception can get you a bit further, but that only works if you already get a stack trace, but it's too short
nadim_ that's what I got, nothing more
jmerelo nadim_: but that's an error that's deep down in NQP so it's better if you post the whole thing here or in StackOverflow... Or both 15:18
timotimo: export RAKUDO_MODULE_DEBUG=1
timotimo: it's for compilation but it could still be useful here 15:19
lizmat .ann points at something gone wrong in a grammar (there's a lot of \.ann() in src/Perl6
)
timotimo try --stagestats to see if it happens in, for example, the optimizer
nadim_ dumping a CallFrame has been challenging, between the Uninstantiable found it and that. not that 15:20
lizmat so it looks like something did not get initialized, and then it gets annotated, and then boom
nadim_ hmm, let me try to reproduce it, I was trying to make it go so far

that's the previous version but get_attributes is the same. unfortunatelly the old version will not dump a CallFrame, it breaks before it gets there. if if it is of interest I can make a branch but changing the code removed the error so I don't thnk it's in get_attributes 15:40

timotimo thanks for the thanks for the thanks
jmerelo bows too 15:49

nadim_: as timotimo says, get_attributes is calling a get_attributes sub?
nadim_ yes
jmerelo nadim_: which is right below...
and there's another _get_attributes... There are a bit too many *get_attributes*... 15:50
I don't see anything that might cause the error, which is probably a bug anyway. 15:51
um, you're defining @a and using it withing a try statement...
Can you define @a in 807 and then assign it a value in the next one? 15:52
@a is not exactly defined when you try and use it, I think...
timotimo true, that's a little bit odd 15:53
but the assignment should return the assigned value, so it *should* be fine
jmerelo timotimo: but you can simply use some other variable. Or none. the try block should return its last value, right? 15:54
timotimo: so simply eliminate @a = inside the try statement
nadim_ yes, I probably needed it as a sub somewhere (my guess is filter, you want power you have to pay for it). and it got complex when I started supporting NativeCall, etc ... blogs.perl.org/users/nadim_khemir/2...-side.html

TreyHarris Is there an at all well-known interlingual for programs that are run in "cmd [GLOBAL_OPTS] subcommand [SUBCOMMAND_OPTS] [args...]" style, like git, docker, etc.? In Perl I think they're most commonly called "App::Cmd-style", but that's obviously not an interlingual term 16:13
16:13 netrino_ left
TreyHarris I've heard "command suite", but I don't think that's common enough--it's certainly not distinctive enough to search on it. I'm hoping there's a term such that, if I were using a new language whose ecosystem I'm not that familiar with, how I'd find if there were utilities for this CLI style, and what they are 16:15
16:20 netrino_ joined
nadim_ jmerelo: yes a list inside a list, it gets rendered as an element in the dump 16:20
jmerelo: the last thing I want when debugging something is the debug tool raising an exception it can't handle
16:21 abraxxa left
nadim_ jmerelo: and since it's just display I believe it is abetter way to handle it. otherwise you get nothing at all, this way you get a partial dump 16:21
16:21 abraxxa joined
jmerelo nadim_: OK :-) 16:21
TreyHarris seems like "subcommand" is the word that frequently turns up what I'm looking for, but by no means 100% (it doesn't Google up the results I'd like to see in Perl 5 or 6, for instance, though it does turn up on-point results that might through concatenation get me what I want) 16:22
kawaii has there been much thought to type safety in perl 6? 16:23
nadim_ TreyHarris: No name I know of, I once wrote a module to handle this kind of interface, handling commands written indifferent languages, a wrapper of sort, I ended with App::Chained because I couldn't find a better name. 16:24
jmerelo kawaii: as in?
nadim_ TreyHarris: with this description: Front end to sub applications in a Svn/Git fashion 16:25
TreyHarris nadim_: *nod* 16:26
16:30 kensanata left, pamplemousse left 16:35 dakkar left
TreyHarris I was looking at the various packages ecosystem knows about and I was thinking--shouldn't it be possible with the new(ish) &ARGS-TO-CAPTURE to create a suite such that bin/foo is the executable calling Foo::&MAIN, and then dispatching commands like `bin/foo bar` to Foo::Bar::&MAIN, such that you leave the Perl 6 built-in opt handling basically intact? Just, given the cmdline `foo {@global_opts} $subcmd 16:37
{@subcmd_opts} {@args}`, before Foo::&MAIN, strip out everything after @global_opts and hang on to it, then run Foo::&MAIN and gather its arguments in a dynamic variable, then do some housekeeping (like, if you used a "terminal" global option, like `--help` or `-V`, _and_ there was anything left squirreled away, fail with USAGE) and replace the @*ARGS with ($subcmd, @subcmd_opts), then call Foo::Bar::&MAIN and
let it handle its arguments normally, too?
jmerelo TreyHarris: zef uses multiple dispatch for its subcommands, with the subcommand as first argument to MAIN. It's not possible to distinguish between flags for command and for subcommand, anyway 16:38
TreyHarris (of course, in practice, you'd probably want some intervening namespace, like Foo::Commands::Bar, etc., but that's trivial.)
nadim_ you want to be abble to displatch to external programs too, git allows you to add your own commands, sleek 16:40
TreyHarris jmerelo: Hmmm, yes, efficiently you may be right... but looking at &ARGS_TO_CAPTURE, I can see one way to do it: gather up all the known subcommands. Going right to left, look for a known subcommand. Grab the arguments beginning with that subcommand all the way to the right, squirrel them away, and try calling the top-level MAIN. If it fails, see if there's a known subcommand further left in the CLI, prepend 16:42
those args to the ones you squirreled away, and try calling MAIN again. If you never get a successful call, die with USAGE. But if you get a successful call, then you know the squirreled arguments are ones to the subcommand that occupies the head of the remaining args
16:43 domidumont joined 16:44 zakharyas left
TreyHarris nadim_: Putting aside jmerelo's good critique, there's a way: use environment variables for the global options, and if no subcommands match, call an external "main-subcommand" and see if it works. That's how git does it. Marrying that with the solution I just proposed seems difficult, though. 16:44
If you specify that the top-level MAIN can't have freeform arguments (it necessarily has no position arguments), only constrained ones, you can do the dispatching more efficiently because there will never be a case where it's ambiguous whether an argument whose value is a string exactly matching a subcommand name is a subcommand or an argument to some prior subcommand or flag 16:47
hrm, without monkey-patching augmenting, you can't do this in an importable package, though, can you? b/c the module has to mess with the commands' packages' namespaces 16:55
it will always be the case that a single use of augmentation anywhere in a program will have a performance hit on the entire program, right? 16:56

ugexe you can only setup mainline once, so having multiple files with parts of the MAIN will not work 18:53
all MAINs must be in the same file
you can still call Foo::MAIN, you just don't get &MAIN, nor the USAGE to show the stuff for Foo::MAIN (if it wasnt the first MAIN loaded) 18:56
otherwise `bin/zef` would just be `require "bin/zef-fetch"; require "bin/zef-test"; ...`, where each command goes into its own bin/zef-command file 18:57

tobs ah, and in a hash, a Pair can contain a container value
oh no, wait 20:19
I meant to make a Map
m: my $a = %(a => 1, b => my $ = 42, c => 3).Map; dd $a; $a<b> = 666; dd $a
camelia Map $a = $(Map.new((:a(1),:b(42),:c(3))))
Cannot change key 'b' in an immutable Map

hythm_ general question: lets say I want to connect to two package repositories, make a query for a package, combine the result from all repos and process it 21:15
what im thinking is to create an Array of Cro::HTTP:Client (with specific base-uri to each repo). and call @a>>.get. then process the result 21:17
timotimo Cro::HTTP::Client can't be used for multiple things at once?
sena_kun hythm_, what is the exact question? the approach you described is doable. 21:19
hythm_ im not sure, ill check that
jnthn If you're not re-using it for multiple requests, there's not that much point making an instance
hythm_ the exact question is, is there a better way to do that? like the way described in "array based objects" advent post? 21:20
let me rephrase 21:22
sena_kun if you can afford it, you can run e.g. `zef info Foo::Bar` and then collect its output, as zef will collect and process metadata for you. if you don't want to rely on something external like this, using Cro::HTTP::Client will do.
tbrowder hi, p6 21:24
timotimo hi TB
tbrowder timotimo: hi!
i'm looking at using win 10 (yuck) to intro folks to p6. can inline::perl5 work there? 21:26
21:26 johnjohn101 left
timotimo as long as there's access to a compiler that can build the p5helper, probably. also it needs a perl5 built with "multiplicity", so you'll potentially have to build your own perl5 anyway 21:26
Xliff jnthn: Any further thoughts on github.com/croservices/cro-http/pull/39 21:31

*marketing? for p5 and p6?
probably 21:46

yoleaux 24 Mar 2019 22:44Z <japhb> ab6tract: Saw the follow up email, thanks! SGTM, but can't work on it right now because of $day-job stuff. I'll keep it on my back burner for fun coding time though. :-)
timotimo could be, but isn't building a perl 5 distribution a bunch of work?
i mean, if you're on win10, why not use the built-in linux compatibility stuff 21:47
tbrowder for one thing, i'm trying to deal with very restrictive win 10 networks like local county and city governments that don't like to change anything. for instance, our new senior center has no non-ms programs, and anything else has to be runnable in the edge browser. 21:50
timotimo ah, i see

hythm_ apology for the delay, i have created SO questionstackoverflow.com/questions/562654...of-objects 21:50

tbrowder timotimo: thnx 21:51
timotimo sorry, i haven't a clue :( 21:52
hythm_: that's fine, but it's a bit wordy; personally, i would perhaps not even have OO in there at all 21:54
21:55 ab6tract left
timotimo if you have an array-based object, you can't have attributes on top of the array storage 21:55
(because arrays are arrays, not general objects, and general objects have attributes) 21:56
hythm_ timotimo, the reason i started with OO is due to after making a request and getting result pack, i would follow that with other requests for every package dependencies , and so on. so i though OO would make it more managable 21:57
aah makes sense
ugexe github.com/ugexe/zef/blob/master/l...ory.pm6#L8 21:58
hythm_ thanks ugexe. checking the method... 22:00
timotimo i suppose that makes sense. will it be fine to look up dependencies of a package first found in A in B?
if you have p6c and cpan for example, would finding JSON::Fast in p6c mean that its dependency Make::Very::Fast would only be searched for on p6c? 22:01
(because you're throwing out duplicates with the unique thing)
if comparing the dists with eqv like that, then the dists can't actually have any data in it that says where it comes from, or else you'll never kick out packages that are "the same" from different ecosystems
hythm_ timotimo, yes it should be fine to get depenedencies from different repo, 22:03
for example if someone hosts a small local repo for a few packages, it would be nice to resolve deps from other repos as well 22:04
timotimo right-o
don't forget we have not only a module's name, but also its authority, which has the ecosystem it comes from as part of the name 22:05
i.e. there are packages with github:timo and cpan:TIMOTIMO
hythm_ aah right, i just tried to make something quickly, probably will end up changing the whole 'unique' part 22:07
also worth noting this is more for Linux packages, like deb and rpm, not for cpan or pip 22:08
timotimo OK
do you know about the specs we have for "native" dependencies? to be put into META6.json? 22:09
ugexe race map race reduce
hythm_ i dont know about that, link? 22:10
timotimo do we have race reduce? 22:11
actually i'm not sure where that document lives. is it on design.perl6.org? i think that page is down still?
ugexe m: say race reduce { $^a }, 1, 2, 3; 22:12

ugexe one day we will sneak the dependency name parser into somewhere... CompUnit::DependencySpecification.from-string maybe github.com/ugexe/zef/blob/master/l...m6#L13-L22 22:16
it will eventually be a requirement for emulates/supercedes/etc
