wander afternoon #perl6 05:34
Recently I attempt to understand how our re-dispatching system works, and learned many of it by reading the blog ↓ 05:37
rakudo.party/post/Perl6-But-Heres-...with-Maybe
however, some questions still remain
the main is, "how to decide who is the next candidate?" 05:38
I know some examples and how they work (github.com/perl6/doc/issues/1689), but is there a complete rule how it choose the next candidate? 05:39
AlexDaniel that's not just about nextsame and friends, the same order is used when you just call something (I think) 05:40
another piece of the puzzle: docs.perl6.org/type/Routine#Trait_is_default 05:41
generally stuff with stricter signatures has higher priority, but I don't know what are these rules exactly 05:43
AlexDaniel relevant code: github.com/perl6/nqp/blob/8c3aedcc...ne.nqp#L59 05:44
wander huh, what it comes to external-defined functions, we can use "which is more narrow". But how about when it intersects with class inherit? 05:45
see the interesting example 05:46

AlexDaniel simcop2387: can it react on something different?
wander: actually that's probably not the right piece of code, but that's all my sleepy mind can find at the moment :) 05:48
wander what does "not the right piece of code" mean? User is not recommended to write code like this? 05:50

wander re-dispatching is a sub-topic of multi-dispatching, i think 06:11
TimToady any dispatcher can re-dispatch, so what 'nextsame' et al. mean depends on the current dispatcher (and they can be nested) 06:12
TimToady one could be in the single-dispatcher, the multi-dispatcher, and the wrap dispatcher all at the same time 06:14
if you don't like the current dispatcher anymore, you can say 'lastcall' to throw it away, and the 'nextsame' will talk to the next innermost dispatcher 06:15
wander I'm supposed to learn what dispatcher is, looks interesting :-) 06:46
wander how about "single-dispatcher"? and in which dispatch the example intersecting re-dispatching with class inherit is 06:53
TimToady those are the same; the class dispatcher finds a single method in a class, but within that class you might have the method defined as several multi methods, so that would turn around and use the multi-dispatcher inside the normal class dispatcher 06:57
and since methods are routines, one of those could have had .wrap called on it, maybe for Aspect Oriented Programming, so that dispatcher might also come into play 06:58
wander emmmmm..got something. So how can we explain this example(gist.github.com/W4anD0eR96/0121e30...018ef163)? I tried to do that but end with losing myself. 07:04
wander Here is no wrapper dispatch. As you mention a new concept "class dispatcher", how does it communicates with multi-dispatcher? 07:06
It calls 'b.f.i' at first, which looks well; the next is a.f.i, huh, no problem; then it back to b.f.a, which messes up logic 07:09
u-ou what is dispatch in programming
I mean, what does the word mean in programming context 07:10
BenGoldberg In general, dispatch in programming means a lookup table of some sort which is keyed by a name, with functions as values. 07:11
u-ou ok 07:12
wander Preamble `sub f(Int) { ... }; sub f(Any) { ... };`, then calls `f(42)`. dispatch is to choose which one to be called, for example. 07:13
BenGoldberg If you hear "multi dispatch", usuaully that means that each value from the lookup table is, instead of a single function, a list of functions... typically with different signatures. Like wander's example ^
TimToady there is only one single-method dispatch there, which goes to an anonymouse proto method that is generated around the most general multi method 07:14
the purpose of that proto is to dispatch to all the multis within its scope, which in this case is all four of them 07:15
wander u-ou: my lexical example miss `multi` 07:15
TimToady so the ordering you see is merely picking based on which parameter types are closer to the actual argument type, and which parameter types are more generic
B is more specific than A, and Int is more specific than Any 07:16
if you only want to redispatch to the multis in a given class, you can provide an explicit proto that can see only those multi methods 07:17
TimToady without that, the autogenerated proto will see all the multis from the object's class, as well as any parent classes of that class 07:19
TimToady the rules in a grammar dispatch by exactly the same visibility rules, but use yet another dispatcher that is smart about LTM (longest token matching), so it calls the methods in order of how much they match 07:21
TimToady this is all pluggable underneath, so you could write your own dispatcher too, but we don't advertise that heavily :) 07:22
but basically, this is how we unify methods and functions and such; everything is a function, but a method is merely a function that happens to be called by a method dispatcher via the class hierarchy 07:25
TimToady bed & 07:26
lookatme good night 07:27
u-ou night :) 07:28
wander I tried adding 'proto' and saw the difference. Now I could explain the very example, in fact I have four multi method whose signatures are (B, Int), (A, Int), (B, Any) and (A, Any). They are flatten so can be sorted from narrow to wide. 07:29
could I write my own dispatcher directly? sounds cool. or it means I can manipulate dispatcher by adding proto properly 07:30
wander good night, thanks a lot for your explanation :) 07:32
buggable New CPAN upload: PDF-Font-0.0.1.tar.gz by WARRINGD cpan.metacpan.org/authors/id/W/WA/...0.1.tar.gz 08:03
wander suggest fixing this issue as soon as possible(github.com/perl6/doc/issues/1692) 08:55
wander I cannot work it out because everything goes well locally. It has nothing to do with our commit, maybe. 08:57
DrForr I'd forgotten how well perl symbols and LaTeX don't play together. 11:24
wander .ask TimToady could you please reply this(irclog.perlgeek.de/perl6/2017-11-29#i_15506760) when you're free? I'm quite curious. thanks. 12:18
yoleaux wander: I'll pass your message to TimToady.
Zoffix What was it that aren't closures? classes/roles or methods too? 12:21
wander huh? 12:23
Zoffix Yeah, I think it's just classe/roles; methods do close over class body but not stuff beyond 12:25
DrForr Ah, wrong package, forgot. 12:27
Zoffix man, can't look at AST on this dumb phone :(
Zoffix jnthn: you around? What was it that aren't closures? Methods aren't closures? Was just looking at the Proxy examples here and see methods closing over a variable; is that fine? docs.perl6.org/type/Proxy 12:30
Zoffix m: my ($m, $s) = do { my $x = 42; my method { $x }, { $x = $^v } }; $s(100); say $m($) 12:38
camelia 100
Zoffix shrugs
Methods ain't closures based on this: github.com/rakudo/rakudo/commit/23...50ec570b9d 12:43
But I don't understand how above example works if they're not and also whether the Proxy example is goo
Zoffix wander: "latest version" is what exactly? 12:48
To me it means latest Rakudo release, to some, latest Star release, to others, the HEAD commit when you wrote that Issue
Zoffix That's for D#1692 12:49
synopsebot D#1692 [open]: github.com/perl6/doc/issues/1692 [build] Build fail strange
Zoffix Gotta be rakudo issue. Latest pod changes, likely 12:50
wander as mention"latest version", I mean the latest perl6/doc version(at that time, 81de65a ). 12:51
ok, let me pull the latest Rakudo and try it again 12:52
Zoffix Ah, I thought you meant latest rakudo version 12:53
Zoffix & 12:54
wander :P 12:54
pmurias hi 12:57
jnthn .tell Zoffix Anonymous methods actually are closures. The thing that makes things "not a closure" is when they are installed somewhere at compile time. A type has a single meta-object with a single method table. 13:03
yoleaux jnthn: I'll pass your message to Zoffix.
Altreus What is the ($) for in zoffix's bot example? 13:05
dasfagggdhkjh Altreus: $m has a Callable in it, the $m() calls it, and the $ is a anonymous state variable that in this case just serves to provide a dummy value for a routine that expects one positional argument. docs.perl6.org/language/variables#...$_Variable 13:24
perlawhirl is there any reason why argless .classify() shouldn't just classify against the value? 13:37
m: say <A A A A B B B C C D>.classify({ $_ })
camelia {A => [A A A A], B => [B B B], C => [C C], D => [D]}
perlawhirl m: say <A A A A B B B C C D>.classify(*)
camelia Doesn't make sense to classify with itself

perlawhirl it does tho
m: say <A A A A B B B C C D>.classify() # :(
camelia Must specify something to classify with, a Callable, Hash or List

timotimo zoffix, it's very problematic to show methods being passed to the proxy constructor; you can't use $!foo syntax in there without making things explode rather violently in most cases 13:45
m: class test { has $.something; has $!foo; method getfoo is rw { Proxy.new(FETCH => method() { $!foo }; STORE => method($n) { $!foo = $n } } }; test.new.getfoo = 99 13:46

camelia P6opaque: no such attribute '$!foo' on type test in a Proxy when trying to get a value
in method <anon> at <tmp> line 1
in block <unit> at <tmp> line 1
Altreus Is it because it was declared as a method so it expects a $self? 13:56
timotimo it's a little more tricky than that 13:58
when code for $!foo is generated it'll look around itself to the innermost class definition
that lets it know what type to put into the generated code
but STORE and FETCH are called on the proxy object
so there's code to grab (or set) attribute $!foo in a test object, but the object the method is called on isn't a test at all 13:59
m: class test { has $.something; has $.blah; has $.flob; has $!foo; method getfoo is rw { Proxy.new(FETCH => sub ($p) { $!foo }, STORE => sub ($p, $n) { $!foo = $n }) } }; test.new.getfoo = 99
camelia ( no output )
timotimo here it closes over "self" from the "getfoo" method, which is the test object 14:00
timotimo so now the type of the innermost class definition and the object stored in "self" match up and everything's good 14:00
m: class test { has $.something; has $.blah; has $.flob; has $!foo; method getfoo is rw { Proxy.new(FETCH => sub (\self:) { $!foo }, STORE => sub (\self: $n) { $!foo = $n }) } }; test.new.getfoo = 99 14:01

Zoffix timotimo: what I don't get is why is it taking methods in the first place? 14:02
Zoffix This seems a lot less clunky to use: my $x := do { my @stuff; Proxy.new: :STORE{ @stuff.push: $_ }, :FETCH{ @stuff.join: "|" } }; 14:03
And is in fact what I first wrote this morning until it gave me wrong results and I realized it's passing the proxy object as the first values
Zoffix Or better yet: my $x := Proxy.new: { my @stuff; :STORE{ @stuff.push: $_ }, :FETCH{ @stuff.join: "|" } }; 14:05
Especially if you say it's very problematic to show methods; well, if we don't then we have some explanation to do about why first arg is a dud 14:07
moritz i guess we'd have to add a new API
the old one has annoyed me at times, too 14:08
Proxy.new is in somewhat whitespread use in the ecosystem
Zoffix I can imagine. 14:09

Altreus timotimo: but zoffix's original example didn't actually use a class, which is what made me wonder 14:39
so I guess the reason the call to $m needed a solo $ is that it was declared as a method and therefore needs an invocant?
timotimo what code are you refering to? 14:43
Zoffix Is there any significant difference between `my &foo := {;}` and `my &foo = {;}`? I can see the latter gives true for nqp::iscont, but is there any difference for regular users? 15:17
moritz not really 15:20

[Coke] zef install --deps-only . 15:49
... but that's more for a project with a META6.json file
azawawi hi 15:51
Altreus timotimo: zoffix did this: «my ($m, $s) = do { my $x = 42; my method { $x }, { $x = $^v } }; $s(100); say $m($)» 15:53
$m is declared as a method but isn't run on an object 15:54
so I guess that's what the $ is for
azawawi m: grammar G { rule TOP { ^ <e> $}; rule e { <e> "+" <e> | "a" | "b" | "c" } }; say G.parse('a+c');
camelia (timeout) 15:55
azawawi how do i remove recursion (timeout) from that grammar?
what's a better way to write: grammar G { rule TOP { ^ <e> $}; rule e { <e> "+" <e> | "a" | "b" | "c" } }; say G.parse('a+c');
jast in formal terms this is called left recursion and an easy way to get rid of it is to split the rule in two, e.g.: rule e { <term> "+" <e> | <term> }; rule term { "a" | "b" | "c" }; 15:59
DrForr Looks like you want to do mathematics. I'd look at github.com/drforr/perl6-Grammar-Co.../Infix.pm6 but I'm a bit biased :)
azawawi jast: cool thx 16:01
jast: im a bit rusty on compiler stuff :)
jast I was very, very interested in it for a couple of years, a lot of it has stuck :) 16:02
azawawi jast: left recursion elimination right?
jast yep
azawawi cool
the thing is if you read docs.perl6.org/language/grammars, you dont find any mention of left recursion elimination 16:03
jast right
TimToady we should at least detect it and complain
jast in *principle* it's not necessary to eliminate left recursion in grammars, it just happens to be necessary if the underlying parsing engine uses top-down parsing (e.g. LL(k) parsers)
azawawi TimToady: I totally agree 16:04
it happened to me here... github.com/azawawi/perl6-inline-go...ar.pm6#L58 16:05
jast I kind of like packrat parsers with PEG instead of standard grammars, but those do take some getting used to
azawawi also perl6 is not complaining of undefined rules until they're actually used. This is good and bad while developing/debugging a grammar 16:06
TimToady the other way to fix it is the way Perl 6's grammar does, install some kind of bottom-up parser in a layer-cake
TimToady p6 just throws an operator precedence parser in under the name EXPR 16:06
jast yeah, that would work for pretty much everything you'd ever want to parse, except maybe natural languages :-) 16:07
azawawi btw what type of parsing are perl6 grammars actually doing (behind the scenes)?
jast I can guess, but I have to leave anyway so I'll let someone more knowledgeable answer 16:08
TimToady it's just PEG, but not packrat 16:09
azawawi en.wikipedia.org/wiki/Parsing_expr...on_grammar right? 16:10
jast packrat doesn't inherently solve left recursion issues anyway, it needs some extra treatment
TimToady the power comes from the fact that it writes lexers for you, so you never need to write your own 16:11
p6 grammmars, I mean
and it automatically calculates longest token matching across all the rules that can be a prefix at that spot
azawawi TimToady: thanks 16:13
Looking at sample grammar test code github.com/albastev/Grammar-Modeli...ause.t#L11 , it seems :rule parameter in Grammar.parse is not being used (or known) to perl6 community. 16:16
or it may have been introduced recently

Zoffix Altreus: yeah, it's for the invocant. In the `$foo.method(...)` it gets passed as the first arg, so if you got that Method object in a variable, you need to stick the invocant as the first arg, or use the methodop syntax with that variable: 16:50

azawawi El_Che: it is a go for windows Inline::Go. Thanks :)
Altreus I guess the main difference is that it's in self and not $^a or whatever
Zoffix Yeah
Altreus is that the entire purpose of `method`?
Zoffix Probably
Also, `method`s inside classes will get installed as methods, but `sub`s won't 16:52
Altreus so much to learn :( 16:55
Zoffix You don't need to learn everything in one go :) 16:56
DrForr scrambles around for peanuts to throw.
Zoffix wonders how many ways to call a method we got 16:58
wander azawawi:
Zoffix I'm gonna guess: 40
wander m: grammar G { rule TOP { ^ <e>+ % '+' $}; rule e { "a" | "b" | "c" } }; say G.parse('a+c');
camelia ｢a+c｣
e => ｢a｣
e => ｢c｣
Zoffix No, 80
wander for this special case, I think ^ is elegant enough 16:59
and yes, left recursion is common, we should discuss it in doc.
SmokeMachine Zoffix: is there a list with each way?
wander TimToady: could you please reply this(irclog.perlgeek.de/perl6/2017-11-29#i_15506760) when you're free? I'm quite curious. thanks. 17:00

SmokeMachine Zoffix: Id love to see that list... :)
azawawi what about also warnings on non-existing rules? is perl6 lazy on this case? since i didnt encounter while developing the inline::go grammar until it was used. 17:01
El_Che azawawi: glad to be a useful lurker :) 17:02
jnthn azawawi: They're just method calls, and the missing methods could be provided by a subclass, for example 17:03

azawawi jnthn: ah ok.
Zoffix wander: by the way, jnthn may know more about your overriding dispatcher question 17:04
jnthn Overriding dispatcher? :)
Zoffix :)
jnthn understands the words but not the meaning ;)
Zoffix "<wander> could I write my own dispatcher directly? sounds cool. or it means I can manipulate dispatcher by adding proto properly" 17:05
m: multi x(Int) { say "here" }; multi x (Any) { say "there" }; x 42
camelia here
Zoffix I guess the question is, is there a way to change the way that dispatches and, say, prefer an `Any` candidate over all the rest 17:06
jnthn Hmm
Not *easily*, but of course all things are possible with sufficient evil
Of note, mixing a role into a proto that overrides the !find_best_dispatchee method probably works out 17:07
jnthn The multi-dispatch algo is written in NQP code 17:07
Zoffix neat

Zoffix This form is mentioned in Synopses but isn't implemented. Cuts down on my list :) 17:09
( design.perl6.org/S12.html#Fancy_method_calls )
wander thanks. now I know there is `!find_best_dispatchee`
for the whole story, at first I lost in this code snip(gist.github.com/W4anD0eR96/0121e30...4018ef163) 17:11
then TimToady explained it(irclog.perlgeek.de/perl6/2017-11-2...15506557), where he mentioned terms 'single-dispatcher', 'multi-dispatcher' and 'class-dispatcher'
still I don't have good understanding about there dispatcher, maybe I can explain why choosing a very candidate to dispatch(which is more narrow), but 'single-' and 'class-' look confusing to me 17:12
for what zoffix recurred to, that is because TimToady said one can write his own dispatcher, which I'm curious about, emmm, just curious 17:14
jnthn stackoverflow.com/questions/450472...3#45123753 17:15
I wrote that once to explain the semantics
Zoffix huggable: dispatch :is: stackoverflow.com/questions/450472...3#45123753 17:16

Altreus Zoffix: yes I do Q_Q 17:17
anything I don't know when I write code is going to be code I write again later :P 17:18
Zoffix Well, my original guess was spot on... I'm hopping I missed some form that double the amount of variants to 80.

Zoffix SmokeMachine: ^ you were wondering
There's also a few ways mentioned in the Syn but aren't implemented :) 17:19

camelia FOO
Zoffix And if you accept this as a separate variant, then the number is infinite :) 17:20
SmokeMachine :D

azawawi El_Che: yup that's the ultimate goal 18:22
El_Che: it is actually two-in-one... Grammar + Execution at the end hopefully
El_Che azawawi: and libraries? go get in the background? 18:23
or do you count on a vendor directory?
azawawi to tell you truth i havent thought about it yet :)
El_Che hehe 18:24
azawawi the builtin go packages are good enough so far :) golang.org/pkg/ 18:25
El_Che azawawi: dep is getting there being the official tool, so a dep managed directory could be a requirement 18:26
azawawi github.com/golang/dep ? 18:26
El_Che yep 18:28
because golang dependency management is terrible, there are meany third party tools to manage them. 18:29
dep has the input of many of these third party authors 18:30
I use it, no probs so far :)

simcop2387 ok good. all working as expected now. AlexDaniel, it'll now respond to eval: only if you address it, but will also work with rkeval (rakudo eval) without being addressed. bleval (perl5 blead), and eval5.X (for other perl 5 versions if wanted). i think i also forgot to mention it supports every perl version, from 1 to 5.26+blead. so eval1: eval2: eval3: etc 18:42
AlexDaniel cool, although not quite sure why would we possibly need that here :) 18:43
(perl5 evals I mean) 18:44
simcop2387 compare code? dunno. :) 18:45
though if anybody here worked with lwall way way way back in the day and had access to (and can get it still) I'd love a copy of perl 0 to put on the bot :) 18:46
AlexDaniel around here we try to compare perl5 with perl 6 as much as we compare perl 6 with ruby, python or whatever… :) 18:47
fwiw I'd love a universal eval bot for all languages
simcop2387 that's kind of what the bot has morphed into, it's got rbeval (ruby) and jseval (node). now that i did the massive rewrite to the sandbox for it, i'll probably add python (mostly for the pastebin, it's a pita for oneliners). and a few others. 18:48

simcop2387 there's a lot more execve() calls that i can't defend (i basically have to open it up entirely if i want gcc)
oh neat, i was going to look at tcc but wasn't sure how well it supports newer c standards 18:52
and i kind of want a c++eval too but that's more difficult.

Zoffix geospeck: without candidates you get the proto
tony-o ^ 21:35
geospeck oh I see
Zoffix no, | is a capture, *%_ is a named param slurpy
geospeck thanks Zoffix!
Zoffix geospeck: above you're looking up different routines though. .^lookup is a metamethod, so you're looking up method 'say' on Str object, whereas the second call gives you the &say subroutin 21:37
e
geospeck I think I need the second one 21:38
tony-o Zoffix: you know of a way to get the uname from the uid in pp6 or nqp ?? 21:41
Zoffix tony-o: no idea what those are 21:46
perlpilot tony-o: you mean uid, uname as "user id" and "user name"? If so, you may need to use NativeCall to get at the getpwuid() routine 21:49
tony-o ah 21:53
perlpilot: have you used that in windows at all? is that comp?
perlpilot oh, no. I don't generally use Windows. 21:57
tony-o perlpilot: ty!
perlpilot I'd guess that there's some other routine that you'd use though.
Zoffix calls it a day
But I'll check the backlog for any ideas for examples of the `.+` methodcall op tomorrow
perlpilot maybe look to Perl 5 and the Win32 namespace to see what's done there?
perigrin There should be a POSIX call for that I think and win32 has been vaguely POSIX complient for a while 21:58
perhaps not 21:59
perigrin I may be vastly overesitmating posix 21:59
perlpilot looks like getpwuid() is in POSIX, so ... maybe? 22:01
tony-o: where did you get the uid in the first place?

s0me0n3-unkn0wn patrickz: I initialized cro stub and after that 22:11
patrickz: # HELLO_HOST=localhost HELLO_PORT=20000 HELLO_TLS_KEY=/etc/ssl/private/ssl-cert-snakeoil.key HELLO_TLS_CERT=/etc/ssl/certs/ssl-cert-snakeoil.pem perl6 -Ilib service.p6
s0me0n3-unkn0wn patrickz: (As root, to gain access to /etc/ssal/private; paths are standard Ubuntu certificate/key generated when system is installed) 22:12
patrickz: After that, I can access localhost:20000 with curl 22:13
japhb s0me0n3-unkn0wn: But the fake-tls key/cert didn't work for you? 22:23
tony-o perlpilot:
m: use nqp; my $io = '/tmp/xyz'.IO; $io.spurt('test'); nqp::stat($io.absolute, 10); 22:24
camelia ( no output )
tony-o m: use nqp; my $io = '/tmp/xyz'.IO; $io.spurt('test'); nqp::stat($io.absolute, 10).say;
camelia 1012
tony-o m: use nqp; my $io = '/tmp/xyz'.IO; $io.spurt('test'); nqp::stat($io.absolute, 11).say; #gid 22:25
camelia 100
s0me0n3-unkn0wn japhb: It didn't, should it? %?RESOURCES<fake-tls/server-key.pem> gives Nil to me 22:26
japhb s0me0n3-unkn0wn: Does the file exist? I wonder if there's just a bug in finding it. 22:28
s0me0n3-unkn0wn japhb: How do I know if %?RESOURCES<fake-tls/server-key.pem> is Nil? Sorry, I'm not to good in P6 resources yet 22:35
s0me0n3-unkn0wn japhb: Well, I found out that %?RESOURCES is also Nil :) 22:47
timotimo that could happen when you don't have a META6.json perhaps? 22:48
tyil if it doesnt appear in the META6.json's resources key, it'll be Nil afaik
or if the file doesn't exist in the resources dir
japhb Should be set up here in the sub template: github.com/croservices/cro/blob/ma...#L205-L207 22:49
tyil also, there's no :exists available on %?RESOURCES to check whether a file is set in the resources, I have looked at possibly adding that, but couldn't think up of a clean way to do it 22:50
s0me0n3-unkn0wn It does exit in filesystem and in META6.json but it is uppercase in filesystem and lowercase in META6.json, I don't know it that matters
tyil I think that will matter, as filesystems are usually case sensitive 22:51
s0me0n3-unkn0wn Mine ext4 is case-sensitive definitely :)
