cale2 something that is handy... maybe like a csv parser? 00:00
AlexDaniel is there any way to make perl 6 repl preserve the history? 00:01
I'm using readline
timotimo it should preserve the history when it uses readline 00:03
worst case, use rlwrap 00:04

like, why would you have something like this?
[Coke] part of the xt/examples-compilation.t I'm working on; I can't seem to catch the warning, either. 00:08
AlexDaniel timotimo: no, it doesn't preserve the history if I rerun it
timotimo: normal history works, yes

AlexDaniel no
[Coke] AlexDaniel: the examples compiler wraps every code snippet in an anonymous class so we can test method declarations. 00:12
and type/Int.pod6 has a block with a bunch of constants showing syntax.
and then I golfed it. 00:13
IOninja um... why does it wrap them in a class? 00:14

[Coke] IOninja: Note that my first pass had *ERR overridden into an IO::String 00:17
and yet it was still emitted on the main $*ERR, apparently.
There's no way to get the effect of 'perl6 -c' IN rakudo, is there? 00:19
IOninja prolly don't reach it from dynamic scope or something?
[Coke] (shellig out to 'perl6 -c' is super slow; but using EVAL means I have to actually -run- the code) 00:20
*shelling
timotimo damn 00:21
00:21 pyrimidine left
timotimo it's probably the compilers using "say" and "note" from nqp to output their stuff 00:22

timotimo those don't look at $*OUT and $*ERR i don't think 00:22

[Coke] jezu.
IOninja timotimo: how come $*ERR.close works?
[Coke] nice segfault. also great idea. :) 00:23
IOninja m: say try EVAL 'sub {CHECK return "all is good, bruh"; class :: { 5000; 42 } }()'
camelia Nil
IOninja hm
timotimo because that closes the underlying file descriptor
IOninja timotimo: and $*IN.close doesn't? 00:24
AlexDaniel I still don't buy the idea of wrapping something into a class blindly
timotimo in what way does it not work?
IOninja I still don't get why it's wrapped in a class at all...
[Coke] IOninja: so a bare 'method' works.
which is most of the examples being testing in the Type/ pages.
IOninja timotimo: last three lines in this log: irclog.perlgeek.de/perl6-dev/2017-...i_14129069 00:25
I see.
[Coke] AlexDaniel: What's your alternative?
AlexDaniel [Coke]: add some heuristics to look for methods?
[Coke] Sure, we already have a check, easy enough. 00:26
AlexDaniel … or wrap everything in class :: { method foo { ……… } }
m: class foo { method foo { method abc { 42 } } } 00:27

I guess it don't make any sense for it to work
'cause the sub would be executed after CHECK and INIT and we're asking it to time travel there.
[Coke] IOninja: I jsut need a 'return', I don't need to make it run sooner. 00:33
oh. or I can just wrap it all in if False { }

IOninja hobbs: half a million tweets and 170K facebooks for some nazi guy. I'd say that's celebrity area :) 02:44
cale2 I'm using zef for sure, but I'm looking for the most up-to-date authoring tool as well
IOninja buggable: eco distribution
buggable IOninja, Found 5 results: Test::META, Distribution::Common, Distribution::Common::Remote, Task::Noise, Ddt. See modules.perl6.org/#q=distribution
IOninja buggable: eco Ddt
buggable IOninja, Ddt 'Distribution Development Tool a replacement for mi6': github.com/kalkin/Ddt
IOninja cale2: that's probably the most one. Though I never used any... 02:45
cale2 ahhh, so mi6 is out of date... did not know
IOninja cale2: well... that's just some author's claim.
cale2 I think many newbies will be accustomed to things like `cargo new` or `mix new` and shebam, your directory structure is built
IOninja *[citation needed] :) 02:46
cale2 The citation is literally my own self :)
IOninja And everyone's like you, naturally ;) 02:47

sad if it's abandoned D:
IOninja What makes you think it's abandoned?
Last commit was a month ago.

In fact, if you discount a typo fix, Ddt is only 7 days newer and I never heard of anyone using it, other than its author. 02:50
cale2 ah

I'm looking for help from others to beef that up. Sort of a companion to "most wanted modules" 02:52

02:56 mcmillhj left
andrzejku however there less steps to do but logic is more complicated 02:56
IOninja MY EYES! 02:58
cale2: well, I don't use Perl 6, so it's kinda of little interest to me :)
hobbs well yeah, that's much more complicated code, and doesn't use a simple for loop, and you're dealing with a really small case 02:59
cale2 IOninja: that's what everyone says :P
andrzejku hobbs ? I did tests for 1000 when 999 03:00
is guess number
and binary search is slower every time
hobbs yes, and 1000 is a very small number
andrzejku :S
ok?
what number should I choice
hobbs I suppose the binary search is just fucked up 03:01
IOninja cale2: sounds like you should start showing it to users of Perl 6 then :)
andrzejku Looking for value: 80000
Guessed value: 80000
Increment search 0.0267904761904762
Guessed value: 80000
Binary search 0.0999639665589252
how the fuck find algorithm is implemented in Perl6? 03:02
:D
hobbs well yeah, that too. Actually I'm having a hard time figuring out why your code even *works* for values over 100 instead of looping forever 03:04
I guess because that else case eventually makes it count by 1
andrzejku hobbs it is checked
hobbs meaning what? 03:05
andrzejku for every case there long2(n) computations
and this is constant
while simple increment look up is n
in worst case
however something wrong with perl 03:06
hobbs that would be true if your code wasn't broken.
03:07 labster joined
andrzejku or I need analyze case with list of elements 03:07
what could be more hard to iterate
probably it is perl6 paradox 03:08
if your code need to invoke many things make it simpler and idiotic it would be faster anyway 03:09
:D
hobbs probably you're typing line after line of utter nonsense
which is the same way your code came about :)
andrzejku no
lulsh 03:10
hobbs I added "say $mid" to your binary search loop, notice anything? paste.scsys.co.uk/554563
andrzejku amm shit happend
i hardcoded :D two variables wait 03:11
cale2 andrzejku: IDK about your algorithm, but you should add a MAIN sub to your script. sub MAIN(:$min = 1, :$max = 200) 03:13
and do `my Int $guess = ^$max.pick` 03:14
andrzejku hobbs thnks :) for help now it is working

geekosaur (also, for grins and giggles, try powershell) 06:54
not that it's that likely to help if cmd doesn't work, but...
ZzZombo the thing is, why does it clearly works in IRC and not in the stupid console window? 06:55
geekosaur what are you using for irc?
ZzZombo mIRC
mroy masak, socketpair is mentioned in Synopsis 32 github.com/perl6/specs/blob/master...ary/IO.pod 06:56
geekosaur ok, that'd make sense. the problem with cmd is that it tries to be backward compatible; "chcp 65001" helps to some extent but doesn't 100% remove the backward compat stuff
which is why powershell might do better
mroy, the synopses are quite old at this point. a decision was made to move anything that wasn't portable into the ecosystem, but I don't think anyone's done anything with socketpair yet 06:57
06:58 mr_ron left
mroy thanks geekosaur. was thinking the same in regards to not being portable and the likely reason not in perl6 yet. 06:58
geekosaur ("portable" ~~ /windows || unix/)
mroy seeing the synopses gave me some hope 06:59
that socketpair may be available in perl6 one day

grondilu so basically in rosettacode.org/wiki/Evaluate_binom...ts#Perl_6, I could write: [*] ($^n ... 0) Z/ 1 .. min($n - $^p, $p) .Int 08:14
instead of: ([*] ($^n ... 0) Z/ 1 .. min($n - $^p, $p)).Int
08:16 robertle left
masak grondilu: yes, but I don't think the spaces version is an improvement on the parens version; rather the opposite 08:17
I'm biased, but I do think it's less clear relying on the precedence behavior of the spaces 08:18
it's like `!important` in CSS -- things were already hard enough before it 08:20
in this case, precedence is already challenging enough, and the parens help clarify. with the spaces, you add another dimension of uncertainty and possible confusion
...unless of course your goal is to appear clever above being clear -- in which case, go right ahead :P 08:21

grondilu :/ 08:27
Forth is very respectable a language, don't mock it
masak not my intent to mock anything 08:28
just listing languages that don't parenthesize expressions 08:29
arnsholt Or just use lots and lots of intermediate variables =)
grondilu yeah but you went straight form Forth to Brainf*. But nevermind
masak though I do believe both of those languages use `[` and `]` for delimiting things, so I guess it depends how far your aversion goes
grondilu: can you think of a third language? I'm curious. 08:30
grondilu: for what it's worth, I also admire Forth quite a bit
grondilu not one in mind, no.
masak then I feel less bad for mentioning those two together ;)
arnsholt I almost added Smalltalk, but it does parenthesise expressions. It's just invocations that are paren-less 08:31
masak I still remember (I think it was) nothingmuch who implemented a Forth in Haskell in the early Pugs days 08:32
think he called it "harrorth" or something
and his comment on Forth was that it was much deeper and more interesting than he had previously realized, and that his implementation didn't do it justice
or something to that effect
grondilu yeah, Forth is definitely cool 08:33
masak also, please don't mock Brainfuck :P it may not be a respectable language, but it's a very minimal Turing Tarpit, with emphasis on the "Turing" 08:34
arnsholt I'm a bit sceptical of stack based languages. But that's probably due to my only exposure to them being the BibTeX style language, which is a bit idiosyncratic
masak irclog.perlgeek.de/perl6/search/?n...q=harrorth tells me I got the name of the language ("harrorth") right, as well as the author (nothingmuch) 08:35
but I can't archive.org from where I am, and the original link is dead 08:36
arnsholt: I think there is something genuinely interesting going on in the realm of typed stack-based languages, such as Cat and Kitten
I investigated that a little bit when I was toying with a hobby drawing language :)

ZzZombo It appears I have incapable to understand what exactly is this make stuff and why it it needed. I'm trying to parse a grammar and make a data structure out of it for later use. 11:33
yoleaux 08:12Z <arnsholt> ZzZombo: I get ｢ and ｣ in PuTTY with Courier New, FWIW
timotimo ZzZombo: let me try to explain 11:34
you know how when you capture something in your regex like a <realsuperhero>?
ZzZombo IDK, I tried that as well, with chcp 65001 active, no effect/
timotimo: yes. 11:35
timotimo you can access the things the realsuperhero regex/token matched through $<realsuperhero>?
11:35 pyrimidine left
ZzZombo yup 11:35
11:35 pyrimidine joined, xtreak left
timotimo when you call "make" where you have the $/ that belongs to the realsuperhero regex (i.e. in the realsuperhero regex itself, or in an action method called realsuperhero), that will set the value of $<realsuperhero>.made 11:36
the action method will be called when a match has succeeded, and its most common task is to build a piece of the final datastructure and attach it to the match result using "make" 11:37
of course you're free to put the "make" as close towards the TOP as you want, and grab data from deeper submatches 11:38
moritz though the deeper you go, the more you couple the code to structure of the regexes
timotimo really, action methods is a way to spread out mostly self-contained chunks of "match tree to datastructure" code "closer to" where the match happens 11:39
yes, what moritz said
11:39 xtreak joined
tbrowder mornin #per6 11:39
ZzZombo say I have string 'a { b=z x { y=d} }', I have working grammar to parse that but I don't get how to make a data structure that reflects the given layout using action class. 11:40
11:41 CIAvash left
timotimo the rule that's responsible for b=z would "make $<first>.Str => $<second>.Str" or "make [$<first>.Str, $<second>.Str]" or something like that 11:42
the rule that's responsible for "a { ... }" would do something like "make $<submatches>.map(*.made)" 11:43
tbrowder ref: p6 run command, the last several days i've been warned about possible dire consequences when allowing user strings to be inserted into the command. can anyone show a regex that would warn of all, or at least most, bad chars and char combos that would cause a problem?
ZzZombo yea, I got that one, but I don't see how to "attach" inner group into the root. 11:44
tbrowder would that be useful in the docs?
11:44 Actualeyes left
timotimo well, ideally you'd have a proto regex that'll match either a thing with a =, or a thing with { } 11:44
and you + that
so your $<theprotoregex> will contain all those matches, regardless of whether it's one of the = things or one of the { } things 11:45
and their .made will be a suitable thing to just put into the resulting list
ZzZombo hm... does it have to be a protoregex? Currently it's an alternating group like <key> <value> || <group> 11:46
timotimo doesn't have to 11:47
in that case your best bet is to put it into ( ), so that you have the ordering from that thing 11:48
and then you'd do something like $/.list.map({ $_<key> ?? $_<key>.Str => $_<value>.Str !! $<group>.made })
andrzejku is there something like perl6doc command? 11:52
ZzZombo hmm, you use just 'make stuff' but docs.perl6.org/language/grammars tells me to use '$/.make stuff'. Is it the same? 11:53
ranguard andrzejku: github.com/perl6/doc
andrzejku ranguard, mm? grep? 11:54
ranguard "p6doc -- an attempt to write something like 'perldoc' for Perl 6" - that not what you are after? 11:56

without the URI.new it works
timotimo you're passing a WhateverCode to URI.new, is that what you want?
and you're calling that URI instance with everything in the result of .find
jnthn Probably meant .map({ URI.new(.attr('href')) }) or so 13:38
abraxxa I want to return URI objects instead of Str
IOninja what jnthn said.
jnthn Whatever-currying doesn't happen inside of argument lists
abraxxa that works and is easier to understand, thanks
jnthn It has to be at the top level
IOninja .map: *.attr('href').&{URI.new: $_}; # Fight the Man 13:39
abraxxa wuhhahhaa 13:40
timotimo yup
abraxxa that's even more confusin
confusing
having a block which is called per element is easier to grasp
URI's absolute and relative methods are deprecated 13:41
IOninja abraxxa: I wouldn't recommend using that. It'll croak on many real-world URLs
<a href="foo.bar/whoops a space"></a> <--- try that one 13:42
timotimo or data: urls
IOninja <a href="foo.bar/?I♥u"></a> # that'll choke it too IIRC 13:43
Basically anything that doesn't conform to the spec... and since when web developers rigidly followed the spec :)

IOninja Because of course it's a Pair -_-
rurban: never heard of it. Where did you stumble on it?
rurban docs.perl6.org/language/phasers 14:30
Must have been a very early design. nqp doesnt have it, or not yet
IOninja rurban: don't see it anywhere in the sauce, or specification.
rurban docs.perl6.org/language/phasers#LINK 14:31
IOninja I mean in rakudo's source
jnthn I think it was speculated in response to some discussion or other; the git history of the design docs may have some background.
rurban It's nowhere. If it would be in nqp src/NQP/Actions.nqp
[Coke] that text is directly lifted from design.perl6.org/S04.html, btw.
We should remove it from the doc site. 14:32
IOninja way ahead of you
[Coke] IOninja++ rurban++
rurban Because I want to finalize cperl phases, and this sounded odd. 14:33
jnthn It doesn't make clear what it thinks of as link time, though, nor what it thinks it is for
(Or what problems it would solve)
Geth doc: 5c85fdd331 | (Zoffix Znet)++ | doc/Language/phasers.pod6

rurban Where is S04?
IOninja rurban: design.perl6.org/S04.html
rurban ah, specs 14:38
IOninja speculations are they're now called :}
jnthn (To be clear, the point here being that the test suite is the language specification, not a set of documents.) 14:39
rurban I see. LINK was called FINAL until 2014
14:39 Actualeyes left
rurban larry said 2014: s/FINAL/LINK/ for clarity. We don't want people confusing this with any other kind of finalization 14:40
And he created FINAL in 2013: FINAL phase is after the main application's CHECK phase, 14:41
when the application as a whole commits to optimization policies.
In other words, a FINAL block defined in a module is not run when the
module is compiled (that would be a CHECK instead), but rather when the
application using the module is completing its compilation and linking
14:42 sena_kun joined
IOninja intresting.. 14:42
14:42 g4 left
IOninja never heard of term "linking" used in Perl 6 14:42
rurban So it will be eventually in, with more optimizations (~LTO)
inlining and whole program optimizations. like use oo :final. which is also not in yet 14:43
14:43 lichtkind_ joined
jnthn Part of the lack of hurry on that being that we do inlining across compilation units already even without that pragma. 14:44
rurban So I keep it reserved. in cperl it would be a number, not a string. that's why I have to think forward.
jnthn: it's just a hook, probably not needed for a long time 14:45
jnthn Sure
14:46 itaipu joined
rurban AFGAIK larry wanted ISA finalization be controlled by the app, not the module, so he needed that phase. 14:46
jnthn Just to be clear: back in 2013 it surely wasn't clear that you could sensibly assume deoptimization would be a possibility. In reality, all of the JVM, MoarVM, and v8 do it.
cale2 m: my @evens = $_ if .even for ^25; say @evens;
camelia No such method 'even' for invocant of type 'Int'
in block <unit> at <tmp> line 1
jnthn Once you can deopt, the incentive to declare things like `use oo :final` is greatly reduced. 14:47
cale2 m: my @evens = $_ if $_ %% 2 for ^25; say @evens;
camelia [24]
cale2 m: my @evens = $_ if $_ %% 2 for ^25; say @evens[];

jnthn Since you just speculatively inline whatever fits
rurban like smalltalk, yes
or v8
14:48 lichtkind left
jnthn Yes, the question is what modern runtimes we might wish to target *don't* do it? 14:48
IOninja cale2: you keep assigning a value to the array anew each time, so at the end you have just 24 in it, which is the last value you iterated over. 14:49
rurban I went ahead with more class finalizations, to enable compile-time ISA optimizations, and detect typos in methods and fields.

ugexe github.com/ugexe/Perl6-Net--HTTP/b...rt.pm6#L70 you can try to reuse the thread as long as that error check itself thinks you're using the same thread id 16:04
cale2 IOninja: I see the docs now, thanks. But `is pure` is more about the final result. You can do all sorts of wacky things inside the function as long as the final result "is pure" I guess
Geth doc/coke/examples: 313c01a6e7 | Altai-man++ | META.info

IOninja that sounds... horrible :) 16:06
sena_kun cale2, I'm not a specialist in optimisations, but I doubt a bit that you will gain anything from such declaration(in performance and purity areas, at least).
ugexe because that error check protects you from something that doesn't work right half the time. but sometimes half the time is enough :)
cale2 sena_kun: but you could write a quickcheck type system that greps all of the "is pure" things and makes a million tests for all of them 16:07
sena_kun To properly use purity you need to ban '=' operator(at least in its common sense, not math-related sense). It it obviously non-impreative way. 16:08

sena_kun IOninja, does zef understand that commits before were for old version and it will pull correct commit?
19:34 rindolf left
IOninja doesn't follow the question. 19:35
tony-o_ sena_kun: it depends on how you're versioning your repo
soon, it will take the latest commit prior to the version being bumped.
IOninja oh, now I get it 19:36
19:36 mcmillhj joined
IOninja How does it know which commit got version bumped? 19:36
sena_kun tony-o_, for example, I've had 1.0. Then I do the commit with a version bump. And the next commit won't be pulled if user types something like zef install cool-1.0, right?
tony-o_ ideally, you'd bump the version every time you push but that may or may not be realistic. another option would be 'release'ing your repo
sena_kun I double this question.
tony-o_ IOninja: that information is in the repo unless you erase the commit history 19:37
i have modules.zef.pm providing that info to zef cli right now, ugexe and i are both working on integration
IOninja cool
I don't get how that info is in the repo. You fetch each commit and check if the meta version changed?
tony-o_ sena_kun: right now i believe that it pulls the last commit for that version 19:38
19:38 cdg left
tony-o_ so if you have 6 commits all with META v0.6 then you commit v0.7, it'll pull all 6 commits in v0.6 19:38
sena_kun tony-o_, awesome.
tony-o_ IOninja: a moment, i'll give you a one liner to figure that out

alphah Noop Q: suppose I have a script that takes "add" or "del" as command line arguments, what is best practice to limit accepted args to the script? I'm thinking to create "enum" or a subset" type and pass it to MAIN sub. What would be the best practice for that? 21:50
21:50 RabidGravy joined
[Coke] could also: multi sub MAIN('add', ...) ; multi sub MAIN('del', ....) 21:52
enum support was recently added, but I don't think it's wired into the usage statements yet 21:53
21:56 jjido joined
b2gills m: multi sub MAIN('add', *@args){}; multi sub MAIN('del',*@args){} 21:58
camelia Usage:
<tmp> add [<args> ...]
<tmp> del [<args> ...]

alphah so the script can be called as "./script add <line> <file>" or "./script del <line> <file>" or "./script insert <line> <file>" or ... 22:06

22:12 jjido left, RabidGravy left
b2gills an enum could be used with a USAGE sub 22:13

22:15 gdonald joined
b2gills An enum would probably be better, and possibly faster in the rest of the code you write 22:16
alphah Thanks! 22:17
