ren1us and that just makes it weirder
apparently two say statements and a second call to the circumfix operator confuses moar ._. 00:04

ren1us before i go and waste half an hour writing a base conversion module, does such a thing already exist in the core? 00:57
because i haven't yet found it (granted i'm pretty sure there's a huge repository of information i have yet to find) but it feels like the sort of thing that's lurking in an existing routine call 00:58
psch sprintf?
psch .oO(probably not...) 00:59

avuserow goes by the term "radix" in the spec

ren1us oh yeah that's exactly what i wanted
avuserow not sure how to format something in a particular base though

ren1us i kinda feel like there should be one unified routine for both to and from arbitrary bases, rather than one... thing to go from base n to base 10, then a method to go from base 10 to base m 01:04
Mouq also .unbase

psch not sure what i was looking for :) 01:07
avuserow base64 typically has padding so it's a bit more special. Plus we already have MIME::Base64 in the ecosystem
psch ren1us: i don't think the adverb conversion gets you base10, it gets you a number which gets represented in base10 by convention. similarly, .base returns something Stringy i assume 01:08
the spec says something about :2(0101) being wrong for "confusing a number with its textual representation" 01:09
(the actual example is :8(777) )

Ven (I think they've had "class annotations" (+ array and closure, but not int and stuff, because.) since php 5 or 5.1 ...) 09:41
masak why do innocent discussions about PHP always end up making me depressed, even though I basically expect it by now? :/
Ven because We Ought To Do Better (TM)
Ven gets depressed by Go, but is quite used to php by now ... 09:42
I guess intellij will still be better at telling you if you failed your typing than hack is, lol. 09:43
nwc10 is curious how hippyvm.com/ will pan out 09:44
also, does HHVM use reference counting? 09:45
Ven yeah. has to.
09:45 thou left
Ven PHP exposes it through some functions, sooo :-) 09:45
nwc10 oh right. I also thought that it was implicit, because some stuff relies on it for timely destruction
Ven (it's a major slowdown. 30% of the bytecode emitted by HHVM is ARC) 09:46
nwc10 OK, fun, so HippyVM is going to be "fast but wrong" if it assumes that it can use a GC? 09:47
xfix HHVM uses both reference counting and garbage collection if I remember correctly.
Ven xfix: I didn't said it didn't use gc ... it just has to use ARC :-)
xfix Just like official PHP.
Ven xfix: "official" PHP got GC 3 or 4 years ago, soo 09:48
nwc10: if they only have GC, then yeah. "Though not by a long shot"
xfix Reference counting is pretty much obligatory, because PHP supports RAII.
Ven You don't "support RAII". people just use what's available. But yeah, the fact that it (RAII) has become somewhat "mainstream" 09:49
means that if you only have a GC and some RAII, you don't know when stuff's gonna get freed
xfix GC in PHP has a specific purpose of dealing with cyclic references. It's just in case it's needed. 09:50
timotimo like in python, eh? 09:51
xfix You mean CPython. 09:52
But yes.
timotimo er, yes
as a former pypy contributor (barely), i really should know 09:53
xfix There is RAII of sorts in other Python implementations, but it's implicit RAII using `with` keyword.
It's also in CPython, of course.
Ven (using a keyword to do it kinda makes it explicit) 09:54
xfix Sorry, I meant explicit.
I don't think.

have an idea, really want to use perl6 with java-bridge 12:59
awwaiid mr-foobar: the most recent rakudo star includes the jvm backend
from ... april I think it was
it builds perl6-j . I was able to do "use java::lang::String:from<java>", but I don't know how to instantiate things :)
(could be that isn't a feature of said release) 13:00
mr-foobar awwaiid: i asked last week, jvm backend had some issues :/
[Coke] lizmat: S03-operators/assign.t:209:#?rakudo skip 'Odd number of elements found where hash expected' might be germane to your recent work. 13:01
13:05 anaeem1_ joined
awwaiid ahh 13:06
well it worked for a demo I gave recently, but I didn't do anything java interop related
jnthn awwaiid: .new method calls are mapped to Java constructors, iirc 13:07
awwaiid tried that, get: Method 'new' not found for invocant of class 'java.lang.String' 13:10
psch overloaded constructors probably need the same explicit call as any other overloaded method
awwaiid r: use java::lang::String:from<java> ; my $x = String.new

awwaiid oh it collapses output when they are they same? you people are so fancy! 13:11
jnthn Yeah, if there are overloads that differ by type then you have to specify the overload long name... 13:12
awwaiid oh, so the thing I picked already has a name and that messes with stuff? 13:13
I was just trying to pick something simple :)
jnthn I'll bet new has quite a few constructor overloads..

awwaiid worked really well. The main thing I want in the REPL is tab completion :) 13:39
I've been using ruby's pry a lot lately, so am in the habit of doing "thing.<tab>" 13:40
psch i've been trying myself a bit on gnu-readline bindings a few weeks back, but from what i remember NativeCall stopped me 13:41
i.e. i didn't get callbacks working for rl_bind_key to get e.g. tab completion o 13:42
-o
also it's obviously very unfinished :)
i don't know if the readline that's in core can do tab completion
or "could do tab completion" rather 13:44
ah no, it wasn't callbacks, it was variables 13:45
as in, gnu-readline exports a char* rl_line_buffer, and NativeCall doesn't do that yet 13:46
or didn't, i might have missed something 13:47

FROGGS I mean, it means that we get away from StringBuilders and do it in Java directly 15:23
15:24 ajr is now known as Guest37704
FROGGS this would be kinda slow then perhaps 15:24
15:24 Guest37704 is now known as ajr_
FROGGS and for parrot it would also mean that we port the unicode database from MoarVM to parrot, but perhaps have some indirection for string handling itself 15:24
because parrot uses libicu, and that would be kinda weird to keep it that way 15:25
at the end the MoarVM string handling is a weak spot atm, so it is possible (maybe even likely) to improve in speed when NFG gets implemented 15:26
either that or the string handling gets a rewrite first, including the needed abstractions 15:27

jnthn lizmat: Um...I'm a tiny bit concerned that is oging to over-share.
As in, more than a tiny bit.
m: my $s = Supply.interval(0.25).map({ 'x' x $_ }); $s.tap(&say); $s.tap(&say); sleep 2; 16:03

16:03 Akagi201_ joined
jnthn 4 is certainly wrong. 1 would be wrong too and I worry the patch does that...or am I wrong? 16:03
retupmoca patch will do 2, if it takes the same approach mine did (which I think it does) 16:04
I *think* that patch has the same issue mine did with .close though - it closes the source tap the first time a tap is closed, not after all taps on it are closed 16:06
16:07 btyler_ joined, Akagi201 left
lizmat ah, we need to keep count as well... 16:07
ok, working on that as well
jnthn Well, it's not about counts 16:08
It's about subscriber lists, no?
lizmat as soon as the last tap closes, *then* we need to close the internal tap
is what I'm saying
16:09 btyler left, atroxaper left
lizmat everytime we get a new tap, we increment a counter 16:10
16:10 atroxaper joined
lizmat everytime we get a close, we decrement a counter: close the internal tap when we reach 0 16:10
jnthn: does that make sense?
jnthn My gut feeling tells me that a solution involving a counter is broken and wrong. 16:11
When we $s.tap there, it's meant to tap the map, which in turn taps an interval 16:12
When we $s.tap again, then it again taps the map, which taps a fresh interval
Otherwise you only get one timer.
That's why it was using a lexical for the source tap and closing over it 16:13
For some reason it was also making two entries in @!tappers, or whatever it's called these days, at a guess.
That's the issue that wants fixing, so far as I can see.
And a counter-based fixes sharing a single source tap sounds like it's going to end up with only one timer at the top of the chain. 16:14
16:14 atroxaper left
lizmat jnthn: this is actually *not* about .interval 16:16
jnthn lizmat: Yes, but I can most clearly illustrate the problem with the patch using interval.
16:16 spider-mario left
jnthn Counter-based approaches will probably basically work out for a live supply, but will behave wrongly for an on-demand one. 16:18
16:19 Rotwang joined 16:20 treehug88 joined
lizmat so you're saying we should take a different approach depending on whether the original supply is live or not ? 16:20
16:20 hoverboard joined
jnthn Not at all 16:21
We should have one approach that works for both.
I feel like the patch throws the baby out with the bathwater; instead of hutning a logical bug somewhere that is causing two entries to be made in a place needing one, it instead changes the scopes and lifetimes of things. 16:22
lizmat the logical bug is that the internal tap is just a lexical in a method 16:23
so every call to the tap method gets a new one
jnthn But that's right, no? It should be tapping the source once each time? 16:24
It's that somehow it ends up putting two entries into an @!tappers somewhere. 16:26
lizmat ok, let me check that
jnthn k
(sorry, my attention is split between this and a $dayjob task too...)
retupmoca there's only one entry in @!tappers 16:27
but each source tap calls more on all the tappers

psch lizmat: that's for recreating a java api in perl6 though, isn't it? 17:38
maybe it's useful as a getting-started for improving codegen for jvminterop, i.e. getting overloaded methods properly into perl6-space
lizmat jnthn: I've now verified that with the original code, the second tap on e.g. .flat opens a second tap on the original Supply 17:42
that seems counter intuitive: I mean, if we create a Supply2 from another Supply1, then the number of taps on Supply1 should be independent of the number of taps on Supply2, no? 17:43
jnthn lizmat: That does sound rather weird. I should take a look at that. 17:45
Something's rotten....
As retupmoca also described 17:46
lizmat psch: yes, something that would be worthwhile, no?
but jnthn: that's how I read the code before my change
jnthn lizmat: oh wait I misread
Grr
So each time you tap something you're building up a chain.
lizmat yes, and that's what our patch prevents: so it only does it once 17:47
jnthn Yes but *it should build up a chain*...
Just that the chains are getting tangled. 17:48
Probably because "does Supply" is providing a little too much...
jnthn suspects there's a unification or something too far somewhere in all this 17:49
mr-foobar alright. it seems java.lang.String is loaded, but I can't call new (method) or valueOf(static method)

FROGGS[mobile] then I get some rest and can read backlog
mr-foobar as far as I can say calling conventions and marshalling of perl6<->jvm needs to be done. 18:09
i think i can contribute a test or two, any pointers :)
FROGGS[mobile] mr-foobar++ 18:10
mr-foobar say System.currentTimeMillis(); works ! so i think the hard parts are done.
i used clojurescript. they used a very dumb clj->js and js->clj for data marshalling. 18:12
although I don't know how much special syntax can be given for FFI's 18:13
jnthn Yes, it's just that in the case of ambiguous overloads things need qualifying 18:21
For example, things like $crc.'method/update/(B)V'($_);
(takes a Bool, returns Void, in this case) 18:22
mr-foobar jnthn: is that name mangling from java's side ?
psch docs.oracle.com/javase/specs/jvms/s...jvms-4.3.2 18:23

jnthn's point obviously still stands, the descriptors needs to get corresponding Signatures in perl6-space 18:24
mr-foobar how to convert [1,2,3] <-> java ? 18:25
jnthn psch: oh, you're right 18:27
mr-foobar: At the moment, manually... In the future we could provide various useful converters
Anyway, the syntax for JVM's static overloads isn't something that we made up on our side; it's the JVM's own sig syntax. Thus it's documented elsewhere... 18:28

psch i'm revisiting tr///, and i wonder how i can comfortably convert the .distance method i implemented for it to something that happens completely in Actions... 19:07
writing the whole algorithm as QAST Nodes seems a bit much to me
19:08 raiph joined
psch for reference, a --traget=ast compile of that method (converted to a sub) is about 400 lines of output 19:08
19:09 itz_ joined, moistcherry left
psch that's probably misleading though... i'll just give it a shot to write it as QAST and see where that takes me... 19:09
19:10 lelf joined 19:12 sftp left 19:13 sftp joined
jnthn psch: Writing it in QAST is surely the wrong way... 19:15
psch: What does the distance method do? What's its input/output?
But whatever the case, almost every situation where we'd end up with a huge QAST tree, we put a sub in the setting and call it (QX is one example) 19:17
mr-foobar jnthn: I am thinking of adding test cases into a new rakudo/t/03-javainterop/ folder 19:18
psch jnthn: right, the huge QAST tree is another deterrent
jnthn psch: Yes, it just bulks up Actions.nqp
And would make each tr/// generate huge code too 19:19
psch jnthn: the method calculates the levenshtein distance between tr/// input (i.e. $_ or the ~~ $lhs) and it's output, which is my understanding is equal to the amount of replaced characters
jnthn What does tr/// evaluate to? 19:20
psch output is a Bool with mixed in .Int and .Numeric
so, to clarify
it actually returns a Bool which calculates the distance when evaluated as Numeric
the Bool is $lhs ne $lhs.trans(...) 19:21
where ... is the arguments to tr/// as Pair
jnthn If we can think of a name for it, I'd just create an object that is constructed with $lhs and $lhs.trans(...)
psch ...more or less, i'm explaining badly
jnthn And it implemnts Bool, Numeric, Int...
psch github.com/rakudo/rakudo/pull/284/...e8cac3R935 ... :)
jnthn And then just have QAST that constructs that object.
psch right, timotimo said something similar; i wasn't aware that he meant to add a class to the SETTING 19:22
jnthn Yeah, I'd do that
psch or maybe he didn't, in any case i didn't see that option
jnthn StrDistance or something...
It will be cheaper and neater than mixing into a Bool...
psch the semantics of StrDistance.Bool seem a bit muddy to me on that layer though 19:23
19:23 moistcherry joined
psch but in any case, .Bool would only be used as an optimization i guess 19:24
i.e. if $str ~~ tr/a/b/ { #`[[ we changed stuff ]] } else { #`[[ we didn't ]] }
and inside the if anyone would probably rather use it Numeric anyway
right, i'll do it like that, thanks :) 19:25

psch hrm, i'm stuck at the .new call in Actions 21:06
simply passing QAST::Vars cleary doesn't work because they're not named
putting .named onto the Vars.new() gives complaints about "unknown type BOOTstr" 21:07
i also tried decont and manually constructing the Want/WVal stuff that --target=ast dumps when it gets a "$type.new(...)"
and those both don't work either :/
time for jnthn++'s nqp slides! 21:08
Mouq .ask atroxaper Do you expect Pod::SAX to supercede the current Pod::To::HTML? I ask simply because I don't want to be doing work on something else when someone is working on a better solution.

github.com/peschwa/rakudo/blob/imp....nqp#L5891 # for reference, this is where i'm stuck... :)
the scope the .new call should end up in has the vars, but just QAST::Var doesn't seem to be enough 21:16
maybe i did something else wrong though, i'm not sure
it might also be that the class i'm trying to instantiate isn't known yet; i've added it to the Makefile and can instantiate it from the REPL though 21:17

Mouq: if i was to call a sub i'd have to have that sub declared in perl6-space already, no? 21:25

jnthn OK; I know QAST pretty well so feel free to run a diff by me at some point. 21:52
