sorear diakopter: you know we're working on basically the same project, right? 01:43
diakopter orly
you're porting Cursor/LM to something? 01:44
sorear almost 01:45
I'm working on viv
diakopter yeah
emit_p5, right?
sorear I'm trying to get to the point where STD-parsed STD can be turned into P5
diakopter I'm trying to get to the point where STD-parsed STD can be turned into perlesque
sorear once that's done, it'll be trivial to retarget it to generate perlesque
diakopter oh
:D 01:46
sorear we ought to work together
diakopter yeah but Cursor/LazyMap still need ported
sorear VAST is a very horizontal thing; it should be possible to avoid stepping on each others toes too much
yes
diakopter and their interfaces designed, since they'll likely be different
sorear I'd like to create a lower-level viv IR 01:47
01:47 [mark] joined
diakopter cool 01:47
sorear which will be *after* regex desugaring
which means that there needs to be a "Cursor" API to an extent independant of backend
diakopter yes
sorear also, I'll be gone Fri-Mon 01:48
diakopter I have kindof a full demarcation of parse operations, modeled after p6 regexes (different names in some cases tho) here: csmeta.googlecode.com/svn/trunk/Spr...c/Grammar/ 01:49
and the various Cut operations I implemented in jsmeta but not csmeta yet
there are probably 15-20 operations yet to be added 01:50
or are you talking even lower level....
sorear actually in the long run I plan to rewrite Cursor et al in Perl6 01:53
and share a single implementation between the backends
diakopter doesn't everybody :P
perlesque can be a stepping stone to that. you just gotta put up with functional/OO style only (lacking Perl's "fluent"/inline style) 01:55
01:55 colomon joined
diakopter wait. what? Cursor.pmc is considerably bigger than I remember 01:57
<frown>
hrm 01:59
ok, yes, I'm definitely going to proceed with the 'extend my own grammar engine' idea instead of porting Cursor by hand. lol. 02:00
it'll be much easier to match the semantics
I'll need an "interpreter mode" for each of those combinators 02:01
which is fine
it'll probably be faster anyway

diakopter sorear: whaddya mean "don't mean with cursor" 06:20
is that a threat?
mess
I didn't think I said I'd mess with Cursor...
sorear you blogged about rewriting cursor...
diakopter erm 06:21
sorear and it was a warning, not a threagt
diakopter "goal of either extending Sprixel's grammar engine to cover all of Cursor's capabilities or manually porting Cursor to perlesque"
I don't see "rewriting Cursor [in perl 5, which I assume you meant]" in there 06:22
sorear frankly, I don't understand 80% of Cursor's capabilities
Cursor is already in Perl 5
diakopter and?
sorear I meant reimplementing its functionality in any language
and, therefore rewriting it in perl 5 would make no sense
diakopter ok, that wasn't obvious at all. People rewrite software in the same language all the time. 06:23
sorear I have never heard of "rewrite" implying "in the same language"
ever
diakopter that's the only usage I've ever heard 06:24
ever
snarkyboojum can definitely mean either :) 06:25
sorear right, it's always meant either to me
snarkyboojum though often if it's a rewrite in a different language that's specified "rewrite in <xyz>" as opposed to "rewrite" implying the same lang :) 06:26
snarkyboojum butts out now
sorear when I say "rewrite" I mean "rewrite (and I haven't specified yet whether it's the same language or a different one)" 06:27
life would be so much easier if English meant the same thing to everyone. 06:28
I need to figure out how to get less worked up over it not doing so
diakopter sorear: I'm sorry for even imagining that I'm qualified to understand Cursor.pm6, let alone rewrite/reimplement it. What would you recommend would be a better use of my time?
until you let me know, I won't even consider messing with Cursor
06:29 eternaleye joined
sorear ... 06:30
diakopter Cursor.pmc, I meant 06:31
sorear you make me want to stop talking to other programmers
06:32 Su-Shee joined 06:33 justatheory left
diakopter ok. if "uh. Don't mess with Cursor..." was in any way meant to be light-hearted/jolly, I didn't catch it, and I regret that. 06:35
maybe I've been mistaking my benefit-of-the-doubt canister for my round-tuit canister lately. :| 06:37
sorear: I did already realize that Cursor contains a very large portion of the grammar engine. I suppose I could've made that fact more clear in my blog post. But I have spent a lot of time with STD.pm and parsers/grammars in general the past few years and I'm pretty confident in my ability to reimplement those routines and to mimic the overall architecture. 06:42
otoh, if it proves reasonable to do a mostly-automatic translation of Cursor.pmc to perlesque or something else, all the better. 06:43
sorear diakopter: As long as you realize what you are getting yourself into, I have nothing further to say 06:45
diakopter I very frequently oscillate between indulging NIH/JFDIY on the one side and ... some other option that I don't understand at all. 06:47
hrm, maybe that's part of my problem. 06:48
sorear I'm not familiar with JFDIY
diakopter just ------ do it yourself ... a just-coined variant of JFDI, after which Jifty is named, I think. 06:49

07:05 BrowserUk joined
sorear it's inferred 07:07
like C++, perlesque supports upward type inference 07:08
if the types of variables are known, the type of any expression is

moritz_ masak: how was your talk? 11:44
masak it was a bit on the short side, but I think it was well-received.
the feedback coming back was positive.
jnthn masak: How'd you like Russia? :-)
masak I felt a kinship of a sort with Moscow. 11:45
it's hard to describe.
11:45 fridim joined
jnthn :-) 11:46
masak there were simple things, such as biting into a bread and realizing that my granny used to make that kind of bread... 11:47
I'm also reasonably proud that what little Russian I know helped me naviagte the metro without a problem. 11:48
moritz_
.oO( "It's possible!")
masak :) 11:49
jnthn masak: Yes, a little Russian - especially being able to read - goes a long way down there. :-) 11:50
masak I missed being able to speak better, though. will have to fix that somehow.
jnthn Yeah...I'm hacking on my Russian quite a lot at the moment. Having been to Moscow recently and having Kiev coming up Real Soon is a good motivator, but now I've dug into a routine I'm really enjoying it too. 11:51
moritz_ misses the new talk on feather.perl6.nl/~masak/

colomon jnthn, masak, moritz_: can you guys take a look a the changelog (just pushed update) and see if there is anything more to be added? thanks!
moritz_ ++ turned on an additional 47 test files 11:58
woah
jnthn moritz_: Wow...that looks like a good read.
colomon: Will do shortly.
moritz_ if somebody paid me for that, I could imagine spending half of my work time on writing such documents :-) 11:59
masak oh, right. release day today. :)
moritz_ colomon: I've already put in those changes that I thought essential... so if you added more stuff, it's what I missed in the first place :-)
colomon moritz_++ 12:00
is there a git equivalent of "svn cp" for creating new files from old?
dalek kudo: d855135 | (Solomon Foster)++ | docs/ChangeLog:
Add a few more bits to the changelog.
moritz_ colomon: cp, git add $newflie 12:01

jnthn colomon: + implemented lexical classes
masak there's an interview that Andrew Shitov did with me on Tuesday: perl6.ru/interviews/carl-masak-on-perl6/
jnthn colomon: It was also lexical roles too
masak snarkyboojum++: you're mentioned :)
moritz_ ah, I was not quite sure

colomon jnthn: what should I say about those? 12:01
moritz_ "classes and roles" 12:02
jnthn colomon: Well, "implemented lexical and anonymous classes and roles"
We never had anonymous roles before either :-)
snarkyboojum masak: really? cool! :)
colomon jnthn++
(added that line locally)
snarkyboojum masak: thanks for the mention :)
jnthn colomon: Otherwise looks pretty good. 12:03
masak snarkyboojum: it's the least I could do. I should have emphasized your role more in the talk as well. 12:04

why does a lexical sub take precedence over a type name?

Since we decide at parse time.
moritz_ but the sub is also known at parse time

pmichaud + pir::set__vps($meth, $meth_name); 12:42
...really?
moritz_ why not?
pmichaud what kind of object is $meth?
moritz_ a parrot Sub
pmichaud weird 12:43
moritz_ it's the clunky interface to set the sub name
pmichaud right
that's what I find weird
has it always been that way?
moritz_ that's what the closure earlier in the method compiles down to
jnthn pmichaud: Yes, 'fraid so.
pmichaud: Like, for ages.
moritz_ is NQP not supposed to build parrot Subs?
pmichaud moritz_: no, what is being done there is fine. 12:44
12:44 justatheory left
pmichaud I was just surprised to see that the 'set' opcode was the way to set a sub's name. :-| 12:44
jnthn pmichaud: I don't think there's a method set_name to do it.
pmichaud: I agree it'd be preferable.
pmichaud that's fine
maybe a comment in the rakudo source that makes it clear we're setting the sub's name 12:45
because that's a little.... obscure
jnthn +1
moritz_ ok, I can add that
pmichaud also, pir::clone__PP can be just pir::clone, I think.
(okay to leave with signature for now)
moritz_ is there a general rule about when the sig can be left out?
12:45 ejs joined
pmichaud not really 12:46
the opcodes that pct knows about don't require the signature
masak moritz_ and others: ping. talk is now up at feather.perl6.nl/~masak/
jnthn always ers on the side of "pct won't know it"
pmichaud in some cases, the opcodes have to have the signatures because there are multiple variants and pct can't be sure which one is intended
well, eventually we'll have to replace all of those pir:: signatured opcodes with something else if we want to port to a different backend 12:47
moritz_ well, there's not much point in cloning non-PMCs
pmichaud (used to be able to clone strings, but can't any more, and it was rare to begin with)
moritz_ yes, I know
pmichaud and the pir:: opcodes will likely become nqp:: or something else for common things
like clone, and add, and ...
jnthn masak: Heh, I didn't expect *that* comment of mine to make it into the talk. :-P 12:48
masak :D
pmichaud is colomon++ still up for today's release?

but since it isn't in the case of finite lists...
dalek kudo: 1c32466 | Coke++ | docs/release_guide.pod:
remove extra punctuation.
 14:19
masak well, what's the semantics of `@a = gather for 1..* { take $_ }` ?
moritz_ it's supposed to return a lazy, infinite list 14:20
but it's not guarantueed to return control flow after the first take()
it's allowed to return after 10th take() if the compiler thinks that's more efficient 14:21
colomon masak: I don't think we actually know yet. 14:22
masak colomon: ok.
mathw Laziness is cool, but difficult

colomon oh, hey, just remembered I've forgotten to look at the roadmap
masak also, I'm still on the lookout for a good suggestion for where to place to project icons. I don't like that they displace the project name and break the nice left margin.
moritz_ masak: then displace all project names 14:24
masak: and make the left margin a bit smaller
ruoso diakopter, the thorn language seems to use a kind of explicitness about threading that we're trying to avoid...
phenny ruoso: 07:42Z <BrowserUk> tell ruoso we could to & fro for ever about whether IO needs a kernel thread or not, and the benefits or otherwise. I spent yesterday knocking up a crude runnable demo to try and give us some feel for the likely benefits. It might be done already were it not that I always have trouble implementing ring buffers. Still chasing a once-per-cycle out-by-one error :(
masak moritz_: I should try that. I fear it might look bad; but I really should withhold judgment and just go for it.
moritz_ or just use a table 14:25
it's tabular data, after all
and it's easy to get the layout right with a table
masak the rationale for using a table is indeed bigger now that we effectively have four columns rather than two. 14:27
ruoso BrowserUk, that's an interesting exercise... I'll be waiting for your conclusions
moritz_ masak: or more, if you put each badge into a column on its own 14:28
ruoso diakopter, have you seen a presentation on that subject in the Moose site?

colomon I like bemounds as a word. 15:17
[Coke] parrot tries hard to be -j safe.
moritz_ and it mostly is
[Coke] seems like you could allow the user to override that in Configure.
moritz_ (although I just got a failure for make -j3 install in the parrot release) 15:18
but that could be related to me Ctrl+C'ing the previous build attempt
[Coke] moritz_: does it fail on just 'make' or specifically on the install?
moritz_ [Coke]: I configured parrot, ran 'make', aborted, and then ran 'make -j3 install' 15:19
and it seemd to build parrot (at least it linked some binaries), but didn't install
[Coke] if you can duplicate it on a 'realclean, config, make -j3 install' open a ticket, i'll fix it. 15:21
moritz_ sure; testing the rakudo release first
build and 'make test' were clean 15:22
PerlJam same here. still waiting for make spectest 15:23
[Coke] I died on the build with: 15:24

isBEKaml hey folks, is there anything I can do to help today (apart from building the release rakudo that I'm doing & )? 15:26

isBEKaml and it's *special* with loads of X'mas spirit!

moritz_ colomon: all pass, except that one advent integration test 15:47
isBEKaml thinks something should be done to remove the core.pir bottleneck in a future release...
colomon shall I announce?
moritz_ wfm
masak moritz_: I don't like the thought of using the name 'u4x' for anything official. the tale behind the name 'proto' shows how easily things get established, and how hard they are to change after the fact. also, see 'pugs repo'. 15:48
moritz_ got a point there
colomon and where? akudo.org, use.perl, perl6-language, perl6-announce, perl6-users, and others seems a little perl6 mailing list heavy.

Or at least submitted to be added to the front page.
BrowserUk had to think about polling asynch IO for serveral long seconds (thinking Oh! No!), before the P(h)enny dropped :)
ruoso hadn't understood until BrowserUk's comment 16:43
BrowserUk ruoso: (As your around), I tried to use go to produce the demo I mentioned, but it's still to flakey. I've coded it in Perl 5, but the GIL and slow shared mem implementation do do it justice. I'm now trying Erlang, but progress is slow. 16:48
*you're
*do do (appropriate:) don't do... 16:49
ruoso what I'm thinking now is that we should assume the interpreter should support different strategies
and some hint in the code to help it decide which one to choose 16:50
TimToady [Coke]: I think of ^ as the "upto" operator
masak nom & 16:52
16:52 masak left
ruoso basically it can go from co-routine-based-cooperative-threading for intensive IO 16:52
colomon use.perl story submitted. 16:53
ruoso to as-many-os-threads-as-necessary
16:53 Eevee joined
BrowserUk Outside of a working demo, the best explaination I can come up with is Amdahl's Law. Starting a whole new kernel thread to support a single IO (sequence)--when that thread would spend most of it's time just waiting for disk/socket/etc., will produce negligable extra gains once you've already threaded the two exspensive calculations. 16:53
ruoso sure sure... the idea is not mixing the strategies in the same code 16:54
16:54 dakkar left
ruoso but choosing one or the other depending on the code 16:54
BrowserUk However, having a single kernel thread sitting around in every process that cooperatively threads all IO requests, and deals with signals/system messages(on Win), is a good idea. 16:55
ruoso hmm... 16:56
but you're just moving the problem from one place to another
BrowserUk How so? 16:57
(And which problem?)
ruoso because the code that will deal with the data coming/going from/to the IO requests will still need to deal with the communication from that thread to they (as opposed to from the OS to them)
colomon perl6 mailing lists "spammed". according to release guild, now time to celebrate.
PerlJam colomon++ yay!
BrowserUk Isn't that where ==> comes in? 16:58
ruoso ==> is just a pipe
BrowserUk (Or <==) 16:59
ruoso you're just moving the buffer from the OS to the program memory
but you still need a buffer
so, no gain
TimToady er, avoiding the OS can be a huge performance gain 17:00
ruoso considering ==> could operate directly in the OS buffe
TimToady, but it's not avoiding... it's just doing that in a single thread
diakopter ruoso: no I didn't see that
BrowserUk Yes, but if IO requests (attached to a pipe), pass their end of that pipe to an appropriate routine in the IO/Event thread
17:00 silug left
BrowserUk Moving which buffer from the OS? 17:01
ruoso considering the following code...
@a <== map { expensive_op_1($_) } <== { expensive_op_2($_) } <== $*IN 17:02
17:02 lokpest joined, \shade\ is now known as {shade}, lokpest left
ruoso you can't have the expensive_op_2 happening in the IO thread 17:02
since it's too expensive for cooperative-threading 17:03
17:03 {shade} is now known as \shade\
ruoso so, if you have a thread that does all the IO operations 17:03
you still need to have a buffer with the data read from the OS and still to be sent to the worker thread 17:04
BrowserUk No. It doesn't Expensive_op_2 runs in a Kernel thread and has one end of that last pipe. $*IN actuall sends a message to the coop thread stating the IO req parameters and passing teh other end of that last pipe.
And the IO thread uses asynchronous read 17:05
ruoso hmm... so you wouldn't be doing all IO requests cooperatively threaded
BrowserUk Yes I would. 17:06
17:06 TiMBuS left, ash___ joined
ruoso since the read op would be done in the worker thread directly 17:06
BrowserUk coop thread == IO thread
ETOOMANYTHREADS :)
Where does "worker trhead" come from?
ruoso it's the thread running the expensive operation

TimToady must wander off, alas; play nicely, kids... :)
BrowserUk needs to produce demo....
17:08 ejs left
BrowserUk The thred running teh expesive operation read from the last pipe. The IO thread writes to it, once the data arrives from disk 17:09
ruoso the point is, why not have the original pipe in the therad running the expensive operation?
BrowserUk But pipes are *between* threads aren't they? Not "in" them? 17:10
ruoso I mean... why not having the thread running the expensive operation to read on the original pipe
BrowserUk If the expensive tread wants to read directly from the disk, it doesn't need a pipe. 17:11
ruoso I think we lost ourselves in the discussion...
BrowserUk I don;t know what you mean by "original pipe".
Indeed.
isBEKaml moritz_: ok, I banged up some code. Looks a little hackish, though and needs cleaning up modules.. 17:12
moritz_ isBEKaml: great
ruoso BrowserUk, considering the snippet I posted... I see today two different scenarios...
BrowserUk I'll draw a diagram of why *I* mean and paste it somewhere...
Okay; belay that! Listening.
ruoso 1) all the code runs in event-based-cooperative-threading (usefull for non-expensive operations) 17:13
2) the code runs in different threads (usefull for expensive operations)
BrowserUk Why just those two? What not 3) All IO runs in the IO thread (cooperatively sharing a single kernel thread for operations that are mostly waiting), and expensive operations (can) start a new kernel thread for their duration. 17:15
I have to go for a while: bbl 17:16
ruoso will try to reorganize the ideas

ruoso @a <== map { non_expensive_op_1($_) } <== amap { expensive_op($_) } <== map { non_expensive_op_2($_) } <== $*IN 17:25

BrowserUk ruoso: re:@a <== map { non_expensive_op_1($_) } <== amap { expensive_op($_) } <== map { non_expensive_op_2($_) } <== $*IN What is the function of the <== in that if amap starts a thread? 18:02
Why not just: @a <== map { non_expensive_op_1($_) } amap { expensive_op($_) } map { non_expensive_op_2($_) } $*IN
With the remaining <== becoming simply = 18:03
ruoso BrowserUk, indeed... so probably the feed means openning a new thread
18:03 Jedai joined
ruoso and I think I'm back to the "implicit event-based programming" 18:04
which basically means... unless some specific operators define it, it goes in cooperative-threading for its regular operations... 18:05
BrowserUk I thought that <== (originally) meant "lazy". So ... <== $*IN doesn't construct a list, but rather supplies values on demand.
ruoso BrowserUk, it's not *just* lazy 18:06
it also means it is lazy
but, in fact, the eagerness in @a = map { .. }, $*IN happens in the list assignemtn 18:07
not in the map arguments
in that case... 18:08
@a := map { inexpensive_op($_) }, $*IN;
hmm...
BrowserUk Before you posted that lot I'd started to type : For example, I can't see the purpose of @a <== map{ ... ?
ruoso the purpose is allowing the interpreter to batch process @a while the code is still flowing... 18:09
for instance...
[Coke] moritz_: do you have a fix for the gcd thing, or do you want me to fix it?
ruoso @a = map {... # the list assignment forces mostly eager evaluation
@a := map {... # is mostly lazy, but the interpreter won't have time to process yet 18:10
@a <== map {... # is mostly lazy, and the interpreter will spawn that processing in parallel 18:11
BrowserUk Hm. (I thinking-but not yet arguing) That's backward.
ruoso I think I'm getting to cooperative-event-based unless explicitly said otherwise (with <==, or any hyper operator) 18:13
moritz_ [Coke]: have a fix locally, just waited for spectest to finish before I pushed
[Coke] moritz_: ah. it was a comment in a commit. Anyone mind if I bump parrot REVISION?
moritz_: oh, you have it. hokay.
moritz_ .. and pushed 18:14
BrowserUk At compile-time, @=map{... you know the destination is @a. So why not have map populate @a directly, rather than having to apply smarts to @a to take values individually? 18:15
dalek kudo: e6863e4 | moritz++ | (2 files):
bump PARROT_REVISION, and load obscure_ops
 18:16
ruoso BrowserUk, my saying doesn't deny that... it's just *when* it happens
plain assignemnt makes it happen at that moment (except when infinite)
bind is replacing the variable for the map return buffer 18:17
feed explicitly says that it should be done in parallel 18:18

BrowserUk I'll need you to explain "ruosoI think I'm getting to cooperative-event-based unless explicitly said otherwise (with <==, or any hyper operator)" a bit more. And maybe in a paste/post/or email? one line at a time interspersed with other stuff is confusing (To me anyway). I'm still thinking about one line and ten more appear.
BrowserUk is going to go away and draw my little pictures and try to illustrate what I envisage "end-to-end". 18:20
ruoso just trying to summarize (will need to go away for a while): Inside one thread, several coroutines may run in cooperative-threading, they get suspended when they try to read a lazy-and-still-not-evaluated value, they are resumed when the data they are expecting gets ready
some operators (feed and hyper operators) explicitly tells the interpreter to spawn a worker thread to handle that code 18:21
isBEKaml moritz_: yes.. that's from pod2html, thingy.. you can just remove the variable referred to in --cssfile and try again? 18:22
BrowserUk And would those worker threads run cooperative shcedulers?
ruoso BrowserUk, possibly, yes....
isBEKaml moritz_: I assume you're pointing to the location in the document root ?
moritz_ yes
isBEKaml if so, --css=/style.css would do, I guess..
moritz_ right
ruoso BrowserUk, in fact, almost certainly, yes... because the code to be ran in parallel might have other lazy values, and, therefore, they might get suspended and resumed using the same principle 18:23
isBEKaml if that works, I can push that in. I was using it for debugging the script here and generating it to a different folder..
BrowserUk So, you end up with lots of kernel threads, each running cooperative threads. I hate to think about trying to reason about how that lot will interact. 18:24
moritz_ too late

ash___ aren't there multiple ways of making lists lazy?

diakopter moritz_: what did this mean: <@moritz_> $.foo is a method call 20:41
[Coke] if you can explain gather/take to me, I can translate it. =-)
pmurias it calls the foo method
diakopter oh, you're saying the setter/getter are method calls
jnthn moritz_: Do you just want to iterate over it?
moritz_: If so
pmurias diakopter: yes
PerlJam pmurias: rakudo doesn't grok "int" yet
jnthn $P0 = getattribute the_enum_map, '$!storage'
$P1 = iter $P0
And then see some PIR iterator code somewhere else in the codebase 20:42
moritz_: Bit evil, but you know its an EnumMap, so...
moritz_ jnthn: I just want to return an iterator...
so returning $P1 in your example
pmurias diakopter: has $.foo defines both a $!foo and a getter foo method
jnthn diakopter: It's a bit "fun" becuase has $.foo # declaring a method as well as an attribute
moritz_: Ah...where?
moritz_ in EnumMap
wait 20:43
jnthn We don't have a .iterator() method on EnumMap?
jnthn was sure that was implemented
moritz_ we have
[Coke] if you just want the pir iterator, you have the pir:: call right there. 20:44
moritz_ wait.. is method iterator() in Perl 6 land suppose to iterate, or to return an iterator?
[Coke]: that's the method I want to translate to PIR
diakopter ok, so if I just say that all attributes are by default rw in perlesque, it'll all be kosher-ish
jnthn moritz_: To return one 20:45
moritz_ and gather/take is a form to construct an iterator
ok
jnthn Right.
But we have to be careful here
moritz_ now it starts to make sense... more or less
20:45 hercynium joined
jnthn Because Parrot iterators and Perl 6 iterators work quite differently. 20:45
(Perl 6 signals the end with EMPTY sentinal)
[Coke] so you do want a more literal translate of that from p6 to pir. 20:46

I'm trying to grok how lexical scopes work. I've been doing thing for a few weeks now, but I thought I'd ask some pointed questions tonight, and maybe reach enlightenment. 21:21
jnthn лолетомезак!
masak :)
that's not a з in my name...
and it's more of an э than an е. 21:22
21:22 quietfanatic joined
jnthn How do you like to translit it? 21:22
мэсак?
masak da.
jnthn: maybe you can be my guide through the lexical scopes jungle?
jnthn Maybe... ;-) 21:23
masak I believe my questions at least partly touch them there protolexpads.
jnthn Ah yes.
Those things we so need but so don't have in Rakudo.
masak nod. 21:24
so, here's where I'm a bit fuzzy right now.
from a discussion earlier this month with TimToady, I gathered that a loop block scope is in some sense 'the same' through each iteration.
maybe it gets reset between iterations, but it's definitely the same something each time around. 21:25
on the other hand, in a fibonacci-like function, it cannot be the same, because then fibonacci really wouldn't work.
so my question is: when do I know when different dynamic scopes map to 'the same' static block, and when they don't? 21:26
jnthn I see it as more of a class vs object analogy.
masak ok.
jnthn That is, there's a bunch of stuff that's the same, but you get an "instance" per call frame.
Apart from in a sense it's more of a clone.
masak ok, so a new call frame gives you new lexical scopes. 21:27
jnthn I guess you could see every object instance as being "like a clone" of the proto-object though I guess.
pmurias diakopter: look at pugs.blogs.com/pugs/2007/10/a-graphical-tra.html
masak aye.
jnthn masak: It gives you a new instance of the storage of the things for that particular "occurence" of the scope, essentially.
masak yeah, but a loop iteration is an "occurrence" of a scope, too. 21:28
jnthn Right.
Since
my @x; loop (my $i = 0; $i < 10; $i++) { push @x, { $^n + $i } }
Needs to do the Right Thing.
masak C-style loops are never the Right Thing. :P 21:29
sorry, I see what you mean. :)
diakopter pmurias: ok..?
jnthn This happens because the closure inside gets cloned at the point you take the closure. It then also has pointers back down the chain to the outer call frame, so that this does not get garbage collected, like it would if we'd taken no closure. 21:30
And that's how stuff ends up referring to the right lexicals in a closure situation. Because they're pointing back to "historical" instances of the scope.
masak TimToady says the closure gets cloned at the entry of the surrounding block. but I guess that amounts to the same in this case.
BrowserUk Is rakudo CPS?
jnthn It's all in a days time travel.
21:30 elmex left
jnthn BrowserUk: Parrot is CPS, and Rakudo is build atop of Parrot, so yes. :-) 21:31
masak: Well, I'm not sure how distinguishable those would be at runtime anyway.
masak jnthn: ok, so there *has* to be 10 instances of the outer scope here, just for the different values of $i to have somewhere to reside.
jnthn: right.
jnthn Right.
masak this helped a lot. thanks.
jnthn Phew, today I was a good guide. :-) 21:32
.oO( though as a guy, I feel I shoulda been a scout... )
masak so, in essence, both recursion and iteration needs to clone their lexical scopes.
jnthn Well, in Parrot, every time you create an invocation record, you get a fresh LexPad along with it.
masak so that closures taken inside them will have something to point into.
jnthn (Context in Parrot terminology)
masak what's the main difference between a sub and a lexpad? 21:33
jnthn has-a
masak nodnod
jnthn Well, not even that
masak but that's just a design thing.
pmurias diakopter: any ideas how to enable something like that for perlesque's grammar?
jnthn I mean
masak why can't a sub just *be* its lexpad?
BrowserUk rakudo: sub x; sub x($I) { --$i and x( $i ) }; x( 10 );
jnthn In Parrot you have a sub which is static
p6eval rakudo e6863e: OUTPUT«Symbol '$i' not predeclared in x␤current instr.: 'perl6;PCT;HLLCompiler;panic' pc 152 (compilers/pct/src/PCT/HLLCompiler.pir:108)␤»
jnthn And a LexInfo which is the static bit of the lexpad. 21:34
BrowserUk rakudo: sub x; sub x(my $I) { --$i and x( $i ) }; x( 10 );
p6eval rakudo e6863e: OUTPUT«Invalid typename in parameter declaration at line 11, near " $I) { --$"␤current instr.: 'perl6;HLL;Grammar;panic' pc 501 (ext/nqp-rx/src/stage0/HLL-s0.pir:327)␤»
21:34 justatheory left
jnthn And then when you invoke the sub, you get a Context which references both of those and has in it a LexPad 21:34
Those are the runtime parts.
masak BrowserUk: $i, not $I
jnthn A Sub (at the Perl 6 level) is quite a bit more 21:35
It has a Signature, a do (a reference to the low-levely thingy that is the code we run), etc.
masak jnthn: the LexInfo says which variables are in the lexpad, yes? I sorta discovered the need for that when doing lexpads for Yapsi :) 21:36
jnthn masak: Right.
masak: In theory, the LexInfo knows all the staticly knowable things.
masak jnthn: well, an ordinary block also has a Signature, doesn't it?
jnthn And the LexPad is just a storage area.
masak: Sure
masak jnthn: uh, I guess that's my question. what's the data model difference between a sub and a block?
jnthn a Sub isa Block at the class hierarchy level 21:37
Additionally, a Sub is mutable.
(in general, a Routine is mutable)
You can call .wrap on a Routine.
masak ah, right. 21:38
jnthn You can ne do that on a Block.
masak ne.
hm, do the Sub and Block things participate in exception catching? 21:39
or is that purely up to runtime parts of Parrot?
jnthn I guess that's mostly an implementation detail.
masak yeah. just thinking about how much to put subs and (other kinds of) blocks in different stacks. 21:40
jnthn Probably it's fair to say that a block is probably in a has-a relationship.
(has-a relationshp with exception handlers, I mean)
That's what it is in Parrot, afaik.
masak aye.
jnthn And would seem to me to be a sane model. 21:41
masak sounds reasonable.

masak spelled '?!'
then `if * ?! * { ... }` would read 'if Whatever whether Whatever, yadda yadda yadda' :P 22:29

bkeeler Anyone else getting failures in t/spec/S05-mass/properties-derived.t? 22:45
22:46 justatheory joined
masak bkeeler: haven't checked, but that sounds familiar. those failures might be intermittent and of unknown origin. 22:46
BrowserUk Hm. I followed the windows link from rakudo.org/how-to-get-rakudo to sourceforge.net/projects/parrotwin32/files/. I've download & installed the big green button at the top...found nothing matching *rakudo* ; So I downloaded & installed setup-parrot-2.4.0-rakudo-29.exe into the same directory. *Still* nothing matching *rakudo* in the entire subtree. How do I get this beast? 22:47
bkeeler masak: thanks. I'll ignore em them
masak BrowserUk: I usually run Rakudo with 'perl6', not 'rakudo'.
'Rakudo' is the name of the implementation; 'perl6' is the name of the executable. 22:48
BrowserUk Yup. Perl6.exe is there after the second download. 22:50
But, it it crashes immediatly with missing dll libgcc_s_sjlj-1.dll :( 22:51
snarkyboojum "the big green button at the top" is a windows help file (chm)? 22:52
BrowserUk: from my reading of the instructions you'll need "setup-parrot-2.4.0-rakudo-29.exe" and "setup-parrot-2.4.0.exe" 22:53
BrowserUk: one is under "parrot-rakudo addon" and the other under "parrotwin32 setup"
BrowserUk Snarky...: Yep. That's the two I've pulled and installed 22:54
22:54 masak left
snarkyboojum ah sweet 22:54
22:54 masak joined
snarkyboojum you didn't mention setup-parrot-2.4.0.exe, so I was just checking 22:54
BrowserUk For me, the "big green button" contains the text "Download now! setup-parrot-2.4.0.exe (8.2 MB)" and links to 'sourceforge.net/projects/parrotwin3...download'. I see no .chm file? 22:57
masak std: sub circumfix:<☃ ☄> ($x) {...}; say ☃ 42 ☄; # TimToady++ -- enabling 'use Snowman::Comet;' 22:58
p6eval std 30732: OUTPUT«ok 00:01 115m␤»
BrowserUk And that missing dll doesn't appear to be a part of the MinGW setup either.
22:59 Psyche^ joined
snarkyboojum BrowserUk: weird - we see different "big green buttons" then :) 22:59
jnthn masak: Aww! Really want that in Rakudo now! :-)
masak alpha: say "foo" ~~ m☃foo☄ 23:00
p6eval alpha 30e0ed: OUTPUT«foo␤»
jnthn I'm not going to re-introduce a bug. :P 23:01
BrowserUk Probably detects different systems from browser sig. If you aren't on Win, then it probably doesn't offer you the .exe download (though a .chm probably wouldn't be much use to you either:)
jnthn: What do you use to build Parrot/perl6? 23:02
23:02 Patterner left, Psyche^ is now known as Patterner, masak left 23:03 masak joined
jnthn BrowserUk: Microsoft VC++ compiler and toolchain, plus ActiveState Perl. 23:03
23:03 masak left
BrowserUk the 2005 or 2008 SDK? 23:03
jnthn Think I have 2005 on my desktop and 2008 on my laptop. 23:04
23:04 gbacon left
BrowserUk Okay. I guess I'll try the sources. (But if anyone knows who controls that source forge project, they should be told that it doesn't work--or the Rakudo.org page should be clearer about what is needed.) 23:06
23:09 quietfanatic joined
diakopter ,,,,,,,,, 23:12
BrowserUk Hm Seems the missing dll is a MinGW problem--bugs.debian.org/cgi-bin/bugreport.c...=539033... So, I guess the sourceforge project uses an automated build and no one actually checks that the results run. (That can't be good for the image of P6) 23:16

quietfanatic That's not supposed to be readonly, is it?
sorear (on setting enums) let's just implement protolexpads and have done with it 23:49
ah, I see already mentioned 23:50

quietfanatic but that works. I guess it's infix:<=>'s bug
sorear no, it's not
.push is being buggy there 23:54
@*INC is readonly
23:54 rv2733 left
quietfanatic You mean @*INC should be readonly? 23:54
sorear no, I mean it is readonly
quietfanatic How am I to manipulate my include dirs then?
sorear the fact that you can modify it with .push is an independant bug
my @*INC ::= @*INC ~ "foo" or something like that 23:55
it's a contextual
you shadow it, you don't change it
quietfanatic That makes sense now that you mention it, but it seems a bit unintuitive.
jnthn Note that ::= is, iirc, now readonly binding, not compile time binding. 23:56
quietfanatic yeah
'::= binding not yet implemented at ...' 23:57
:= doesn't work either.
So, I just can't do it right now?
snarkyboojum you could use push (temporarily) :) 23:58
quietfanatic I suppose that's what I'll do.
