jjore_ Hi, got my speed improvement report at diotalevi.isa-geek.net/~josh/100720...akudo2.txt
apparently at the fastest, it goes 2.65x as fast. Thanks pmichaud++
Since a year ago this was taking hours or never finished, this is now a distinct improvement. 00:28
anywya, it's time for Seattle.pm & 00:29
jnthn Good to hear we've improved, even if it's still hardly fast. :-) 00:32

pmichaud that partially depends on the oscon wireless, I'd wager. Or I could tether via my phone :-) 01:31
colomon pmichaud: I just got a segfault with a very simple (but repetitive) bit of p6.
:(
ingy ufo works for me again \o/
pmichaud colomon: what's the bit of p6? 01:35
colomon something like for 1e10 ... 1 -> $i { $i.say; }
(it's 30000 lines back in my backscroll.)
01:36 plobsing joined
pmichaud it's probably making too many gc-ables 01:36
currently the series operator eats memory when iterated 01:37
sorear the Parrot GC recurses on the C stack when marking objects
pmichaud (at least that's my suspicion)
sorear so if you nest objects more than about 6,000 deep you get a segfault (i386 linux)
our iterators are linked lists
they create a nesting level of objects for each item iterated 01:38
colomon sorear: but "for" shouldn't be keeping them.
but yeah, I guess if they don't GC fast enough they effectively will be keeping them, eh?
pmichaud "for" isn't keeping them, but the GatherIter is.
sorear for is well-established to leak memory, since we don't have sink context yet
pmichaud and that too 01:39
since for goes through a ParrotIter at the moment.
(sink context isn't really an issue -- we can emulate that at any point) 01:40
colomon: ooc, does it fail if you use 'map' instead of 'for' ? 01:43
colomon map with .eager or .munch or something?
pmichaud just map
yeah, with eager.
or try .munch 01:44
.munch probably makes more sense
or repeated shift
or even... (gasp) try sink :-P
colomon .sink works?
pmichaud not .sink
prefix sink
colomon \o/
pmichaud sink (1e10...1).map({ .say }) # or something like that 01:45
01:45 whiteknight left
pmichaud anyway, the current list implementation isn't guaranteed not to leak memory yet. But at least the API isn't one that forces us to have an implementation that leaks memory :-) 01:46
afk, heading to oscon
colomon will report what happens when it happens. :)
oh, that was fast. 01:48
seg fault in about 20,000 iterations.
actual code was something like sink (1e10 ... 1).map(-> $i { $i.say }) 01:49

pmichaud yes, we likely need to clean up either gather or series or both a bit to avoid holding all of the objects. 02:08

sorear pmichaud: I still blame CallContext. 02:14

pmichaud interestingly, the "double gather" bug might not be a problem with gather. 06:11

pmichaud I agree it shows up when gather is used. 06:16
but if I write the gathers directly (as opposed to in a sub/method), it works just fine.
06:16 baest joined
moritz_ it shows up when the *same* gather/take is used twice in a lazy list 06:17
which you don't achieve when writing a gather/take directly
pmichaud okay, that's possible. 06:18
looking.
moritz_ rakudo: say <a b c>.map({$_}).map({$_})
p6eval rakudo 278366: OUTPUT«abc␤»
pmichaud .map doesn't use gather, so it's not relevant.
moritz_ ok
pmichaud this is interesting
consider:
gather { @list.map({ take $_ if $_ > 2 }) } 06:19
should the statement in the gather be considered to be in sink context?
I guess gather must impose sink context on its block.
moritz_ probably
06:20 justatheory left
pmichaud ohhhhhhhhhh 06:21
I think I see the problem.
the gather statement isn't properly cloning its block.
oh wait, that's probably not it. 06:22

pmichaud hard to say -- it's been mixed up with general closure problems from the beginning.

pmichaud %LOADED appears to ... yeah. 06:55

I suspect that needs to be reworked a bit.

timbunce how can I see the contents?
pmichaud might try casting it 07:00
say (CREATE_HASH_FROM_LOW_LEVEL %Perl6::Module::Loader::LOADED).perl;

sorear Juerd: I have occasionally ben tempted to write a cron job to kill all the .o files on my system. I wonder how much collateral damage it would do. 08:44
Juerd Even without gz, a tar would be so much faster to copy around.
08:44 zulon joined
Juerd You don't realise that having so many small files is a problem until you make backups or want to move everything over to a new box 08:44
frettled Juerd: loopback-mounted filesystems :)
sorear Wait. What's the cool FS these days? 08:45
frettled sorear: WAFL and ZFS, still.
moritz_ sorear: btrfs
Juerd frettled: No, that'd be counter productive because then you'll be diffing huge files. Just tar those things that aren't in active use :)
sorear I thought it reverted back to extN after the Reiser backlash
moritz_ finds that he has a public_html/pugs/ and goes wtf and rm -rf 08:46
frettled moritz_: btrfs isn't cool yet, IMHO, since it's not stable
Juerd moritz_: Oh, removing is even better :)
moritz_ ah, that was probably my old git mirror
which is now on github anyway
mathw frettled: but when it is stable... :D
frettled Juerd: I don't think you'd be diffing huge files any more than with tarballs.
Juerd Yeah, we have old mirrors, old checkouts, and old everything all over the filesystem :) 08:47
frettled mathw: I have a bridge to sell you ;)
Juerd frettled: If the mtime doesn't change, you don't have to diff anything.
08:48 snarkyboojum left
frettled Juerd: the idea is to use loopback-mounted filesystems for build trees. When you're done, you're done, and there's a binary blob of a file that you _don't_ diff and don't necessarily move again. It's huge, it's hopefully a sparse file and treated efficiently as such, and easier to move around than a zillion small files. 08:48
pmichaud ...I have '.imc' files in my feather dir?!?!?! 08:49
Juerd frettled: But when you do write to it again, the huge blob changes.
frettled Juerd: but you still don't diff it 08:50
Juerd frettled: big never changing blobs > real build dirs > big changing blobs
moritz_ frettled: the problem is not the lack of technology, but the lack of care
frettled moritz_: mmm
Hmm, but there are merely 4.2 million files in /data on feather6 :)
pmichaud I fear the mental image of huge changing blobs is too much for my brane at 02h00
frettled s/6//
Juerd frettled: Sparse files aren't faster, by the way. They just take up less space. 08:51
moritz_ people could just rm -rf the stuff they haven't used for 3 months, or tar and then rm
frettled Juerd: that's kind of the point (taking up less space)
08:51 timbunce left
Juerd Using up space is not the issue here. 08:51
frettled moritz_: yup
Juerd Having a gazillion tiny files is
moritz_ svn doesn't help there :-)

Juerd I deleted 4 GB of /home/*/.ccache yesterday 08:52
Ooh, nice system load on feather1 now :) 08:53
frettled How long does the backup take, anyway?
moritz_ Juerd: I'm doing a du -sch /home/*, and plan to publish the results later on 08:54
frettled Juerd: 9-10 processes in blocking wait
Juerd frettled: A full backup takes 4,5 hours
moritz_ then I should rather abort it soon :-)
Juerd frettled: An incremental backup takes almost an hour
pmichaud yeah, I'm deleting some old svn checkouts too
frettled Juerd: and what do you use for backups? 08:55
Juerd Great!
frettled: dump
frettled Juerd: aha.
Juerd: try rdiff-backup or BackupPC? All backups are incremental.
Juerd Hah.
No thanks :)
Those are enormous resource hogs. I prefer to continue to actually use the system while backups are being made.
Again, storage is not an issue at all. 08:56
A single full backup with dump is generally faster than an incremental backup with rdiff-backup, and backuppc is much worse in many respects. 08:57
frettled At work, I think a single incremental backup with rsync (which is, performance-wise, comparable with rdiff-backup) takes around 6.5 hours for around 27.2 million files. 09:00
The performance penalty is negligible on our hardware, but that's probably because it's a mid-range SMB RAID system. 09:01

Juerd Oh, here's what happened: dump reads the fs itself, but I gave the path of a mounted filesystem (which in itself is okay). I had feather3 mounted on /mnt, and then feather2 on /mnt too. In Linux itself, this means /mnt is feather2. Dump however reads the mount table and apparently uses the *first* entry rather than the last.
moritz_ oh wow
Juerd Oh well, shouldn't take long to do it again.

masak I'd argue that that's a case where the method might make sense on Real, too. (identity opration)
Juerd my ncdu is still running. 2.8 million files so far.
masak either that, or one chooses consistency over convenience, and forces promotion to Complex. 09:22
moritz_ masak: if you argue that way, 1.re and 1.im should also work
so I'm in favor or keeping it in Complex
masak moritz_: aye.
moritz_: thing is, his use case presupposes that it work on non-Complex, too. 09:23
so at least his expectations are aligned with Work Everywhere.
Juerd (That's a lot. feather2 has 63460 files for 1.4 GB and feather1 has 49 GB in use)

tadzik if my module is a module literally, not a class, how do I call its methods? Let's say I have 'module Foo::Bar' in the .pm file, now calling Foo::Bar.function() says 'method function not found for non object', Foo::Bar::function() fails even funnier. What is the right way? 09:27

Kodi masak: I'm actually not firmly against making DateTimes immutable. I just… I don't see why it would be useful. You shouldn't use DateTimes as hash keys or store them in databases; they're too big and they'll likely include functions (timezones), so they'll be difficult, at best, to serialize.
masak Kodi: the argument about container mutability doesn't quite cut it, because if the object attributes can change, then hash keys etc might be invalidated.

moritz_ Kodi: the question is more, if you use the same DateTime in two places, and one of them is modified, will they be surprised to find that it's also changed in the other place? 12:22
Kodi moritz_: Good point. I guess that would be surprising. It helps that Perl 6 has a builtin clone method. 12:23
Juerd moritz_: s/DateTime/Int/, and no
moritz_: So what's so different about DateTimes that makes it okay to take away their mutability?
I think that's the correct approach to answer if immutability is a good idea :) 12:24
wolverian Juerd: will do.
moritz_ Juerd: I see it the other way round: immutability has lots of advantages
Kodi Juerd: The idea is that, currently, DateTime is actually the odd one out by its mutability. I think.
Juerd If you don't ask what's *different*, then you should at least ask the same questions for other datatimes, and perhaps even make those immutable.

moritz_: Great. Please relay my thanks :)
Kodi moritz_: I see. Largely issues at a lower level than I tend to think in. :) Well, public opinion seems against me, so I guess we should go with immutability. No guarantees I could change the the spec and the implementation in time for Rakudo *, though. 12:28
colomon sorear: you mean, for a .perl method (all .perl methods?) to return a Cat? 12:29
sorear colomon: yes
colomon my initial thought would be yes, but I'm pulling up the spec in another window. 12:30

sorry, S02
Kodi masak: So long as we're all bikeshedding about Temporal, though, let me at least bring up one thought I had from the beginning. Shouldn't there be a TimeOfDay class, such that a DateTime is just a Date + a TimeOfDay? 12:32
masak Kodi: there can't be.
Kodi masak: Why not?
masak well, not with proper limit checking, at least.
and it quickly gets very tricky with time zones and stuff. 12:33
colomon though I guess the question of whether it then makes sense to return an infinite representation for an infinite list .perl is kind of weird, unless eval is smart enough to handle Cats lazily
moritz_ date length depends on the exact day
masak Kodi: I agree that the assymmetry is disturbing, but I've concluded that it has to be this way.
Kodi moritz_: But DateTime already doesn't check for leap seconds.
masak Kodi: dates can exist without times, but not the other way around.
nimiezko rakudo : my @x = 'A'..'ZZ' ; say @x.perl ;
masak Kodi: right. and whether DateTime should check for leap seconds is a tricky issue, to.
Kodi: I'd argue it should.
grondilu is running "make"
Kodi masak: Oh, boy. 12:34
masak Kodi: since it represents "civil time".
frettled masak: well, actually, time-of-day can exist without a day, but it then becomes a very basic class without any of the date baggage
nimiezko rakudo: my @x = 'A'..'ZZ' ; say @x.perl ;
Kodi masak: In fact, I've realized that whether or not DateTime recognizes them explicitly, leap seconds will need some kind of support in Perl 6, in order for Instants to work.

sorear if you want to get a disk running after uncharacterized data corruption? yes, fsck time

ZFS does, however, perform online autocorrection for some categories of data corruption. 14:06

Juerd Apparently, deleting files is Hard. 14:23
185k files left to delete 14:25
frettled It's not hard, but it's one of the more resource consuming operations in ext3.
moritz_ it's even worse on xfs, IME
frettled IIRC, ReiserFS touted quick file deletion. 14:27
The problem in ext3 and XFS is — again, IIRC — that file deletion is a forced synchronous operation. 14:28
ext4 is supposed to have a more efficient inode organization, which also allegedly speeds up file deletion. I haven't tested it yet. 14:29
Juerd ext4 is faster for several operations
But I won't use it in production until dump supports it.
frettled See, now, there's an advantage to using rsync-based backups ;) 14:30
Juerd Yes, it works with any filesystem.
frettled almost any :)
Juerd That flexibility is expensive
14:31 pmichaud_ left
Juerd dump accesses the raw device 14:31
frettled if you have a raw device, that is 14:33
At work, we use rsync because of needed flexibility: the ability to more or less easily restore individual files, or sets of individual files.
Juerd Block device, not the actual bare metal :)
frettled And the backup server handles roughly 90 million inodes in 7.5 hours from three different fileservers without any performance hiccup on the fileservers. 14:34

frettled The surprise is probably in that .. has precedence over ~~, which has precedence over ... 14:43
PerlJam or, as I see it, from a newbie's perspective, the difference between 3 ~~ 0..4 and 3 ~~ 0...4 is *quite* surprising.
frettled …and I now see that the HTML cheatsheet draft somehow has lost the ~~
14:43 paul1234 left
PerlJam This is one of those "different things should look different" areas for me. (And a single extra dot isn't different enough) 14:44
moritz_ PerlJam: welll, even 3 ~~ (0...4) is going to surprise them
TimToady ahem :)
it surprised me
moritz_ also 3.4 and 3..4 is quite different
PerlJam TimToady: indeed! :)
moritz_ and it's also just one extra dot 14:45
TimToady nevertheless, I don't see how it can change from what it is
.. operators on two scalars
PerlJam moritz_: you got me there :)
TimToady ... operates on two lists
moritz_ it's programming. Every character counts. Period.
Juerd moritz_: Whitespace 14:46
moritz_ Juerd: also counts. Good point.
Juerd moritz_: But *more* whitespace doesn't do anything.
(Fortunately!)
sorear TimToady: Should ~ work on Cats?
moritz_ except when it does
like, in quotes
Juerd moritz_: It doesn't. One or five hundred spaces, it's the same thing.
moritz_: Whatever is in quotes, has hardly anything to do with programming.
14:47 dalek left
TimToady sorear: anything you do on a string that doesn't require knowing where the end is should work on a Cat 14:47
Juerd moritz_: It's just data that you never bothered to put elsewhere :)

cono TimToady: add please time methods to Int class, like in ruby :) 14:48

TimToady fortunately ~ is one of those operators where left assoc and list assoc come out to the same thing

pugssvn r31781 | jani++ | ~~ had mysteriously transformed into ~, fixified
wolverian is annoyed that he can't link to e.g. the infix:<...> in S03 directly
TimToady so if you see a cat in the list, you just go lazy, I suspect
moritz_ Juerd: (iirc) more whitespace counts in the closing delimiter of a heredoc
sorear TimToady: so, type dispatch inside the slurpy-loop? 14:49
TimToady or just allow create a cat of cats/strs
Juerd moritz_: That's still within quotes as far as I like to interpret it.

tadzik PerlJam: any ideas? 15:19
PerlJam tadzik: I don't have a clue about that at the moment, but "token keyval" looks like it really wants to be "rule keyval" and be rid of those \s*

tadzik pmichaud told me about this yesterday
moritz_ hm
tadzik and what do you mean, custom ws token?
moritz_ maybe I'm wrong after all
if you have a 'rule something { ... }', all the whitespaces in that rule are notionally replaced to a call to <.ws> 15:24
the default ws token is { <!ww> \s* }, where ww means "within word"
tadzik hmm 15:25
sorear TimToady: What's the difference between WHO and HOW?
moritz_ but in a grammar, you can provide your own ws rule, matchinig spaces, comments etc.
tadzik comments can't appear before keys, so they're not so good as ws tokens
moritz_ so
[section]
#foo 15:26
bar = baz
is forbidden?
erm, s/#/;/
tadzik nope. But ;foo bar = baz cannot be
moritz_ tadzik: then change your comment rule to include the newline
tadzik at the end?
moritz_ yes
tadzik hmm, makes sense
moritz_ token comment { \; \N* \n }
or ';', whatever you prefer 15:27
tadzik I can get rid of dummyline eventually
PerlJam tadzik: I'd probably make that one a rule too
(comment)
tadzik ETOOMANYCHANGES, lemme fix this 15:29
PerlJam (but that's assuming you don't go with the custom ws rule like moritz_ said)
moritz_ it's exactly what custom ws rules are for :-)

or I guess = is also acceptable there
jnthn if you "use Foo" in Rakudo, everything that was marked 'is export' or 'is export(:DEFAULT)' should get exported. 18:32
At least that much works, or "use Test;" (which is all lexical subs) would not :-)

TimToady I'm probably going to go with some kind of default semantics a bit closer to what ajs++ is recommending 18:50
simply because the ... operator is more aware of the final value than .succ is
so the current semantics would be more like "100.A", *.succ ... "109.A" 18:51
and the new semantics could do something saner column by column 18:52
though not necessarily as aware of Unicode props as ajs++ is proposing, if we can do it with filtering 18:54
but it'd be nice to at least get "000" ... "FFF" do do hex :)

rokoteko frettled: that was not my point at all. I wish future generations would also keep programming perl. 19:33
else we (the perl5 people) will be like cobol people in 30 years.

Juerd rokoteko: Many businesses (at least in .nl) are searching for ways to get rid of Perl.

Juerd They're moving towards Python and .Net, in most cases. 19:42
rokoteko which is just bullshit. Ive personally seen this fails. a seasoned perl hacker is so much more productive than a just graduated java programmer the the management has no idea about it.
Juerd Yes, but there's this weird and wrong idea that Perl is dead. 19:43
And it appears to be confirmed by the lack of Perl programmers.
rokoteko Juerd: that might be true. but see the java+xml consultants. I think its about as competent people advertising their languate.
Juerd (OTOH, a single company (Booking.com) seems to employ half of them...) 19:44
rokoteko perl5 wont be dead for atleast 100 years. but Im afraid perl6 will.

you mean, for restarting after a successful match?

19:54 Meldrake left
sorear rokoteko: because Java has been a mature environment for 10 years, Perl 6 for maybe -3 19:55
rokoteko Im starting to think it's mainly because the commercial people are thinking what happens if Timtoady dies. and that's why perl was started from scratch.
sorear do you understand the difference 13 years head start makes?
pmichaud sorear: I capture the current sub if a successful match occurs and there's a possibility of backtracking into the current match
rokoteko sorear: nods. I actually was programming java for a while. and the gurus on java said that perl is good because it has a very mature vm.
pmichaud otherwise, I don't capture the continuation at all. 19:56
sorear rokoteko: they meant perl 5. go to #perl, not here
rokoteko sorear: so perl6 started 13 years ago, or what are you trying to say?

tadzik either hapiness or criticism I guess :) 20:32

moritz_ and then "is export" (when rakudo implements it) 20:41
tadzik not computed in runtime?
moritz_ which has the advantage that you can say color(blue), and get compile-time checking
the enum initialization runs at compile time

I'd like a method to take a DateTime object in any timezone and return a new DateTime in a different timezone, using the offset format from the ISO string (i.e. say DateTime.now().to-timezone('-0800'); ) I'd be willing to write the method myself, in which case I'll wait for your immutability patch to roll in.

supernovus gah, that last message was for Kodi, I'm not talking to myself ;-)
Kodi supernovus: Heh.
moritz_ moritz_: why not? talking to yourself is very natural 20:50
Kodi supernovus: Ja, in-timezone is just like your to-timezone, but it takes an offset in seconds.
tylercurtis moritz_: Why isn't that correct behavior, by the way?
Kodi supernovus: Offsets in seconds now being The Standard Way to think about timezones. 20:51
moritz_ tylercurtis: because silently dropping information is bad[tm]
colomon tylercurtis: and if you want to drop, you can do -> $a, $b? { ... }
tylercurtis moritz_: oh. right. 20:52
moritz_ or pad your list to an even size
tylercurtis misunderstood the problem.
supernovus Kodi: Okay, maybe there should be something to convert between HHMM offsets and Offsets-in-seconds. I guess it could be a helper method or subroutine. Maybe DateTime::strftime should become DateTime::Utils and have a few "helper" methods in it.

21:57 Kodi left
cono jnthn++ works ! :) 21:57
jnthn I do occasionally, yes. 21:58
Oh, you meant the Parrot suggestion :-)
pmichaud jnthn: yes, they're methods on parrot;Sub
jnthn pmichaud: ooh... hmm.
pmichaud: Ah...let me see if I follow this right.
cono jnthn: I mean mine p6 works after your helping :)
jnthn pmichaud: The Parrot sub is the center of attention now.
pmichaud jnthn: correct, because it's the only thing that has a unique identity 21:59
(at least, it's the easiest key)
jnthn cono: \o/ отлично!
tylercurtis jjore_: for some things, it does.
cono jnthn: I shocked!
jnthn pmichaud: Right, I'm just not too sure how to do .wrap now properly... 22:00
pmichaud where's .wrap defined?
jnthn pmichaud: Routine.pir 22:01
pmichaud: I haven't really re-done it properly yet for master or since the closure changes
pmichaud: It's kinda still "to do"
pmichaud yeah
jnthn pmichaud: I was faking it in Zavolaj by just replacing $!do
Which is kidna what I envisioned .wrap doing too 22:02
slavik jnthn: что происходит? 22:03
pmichaud replacing $!do on a clone is probably okay
Tene jnthn: while you're thinking about it, it'll be nice if you can get it working from a sub trait handler, too, btw.
jnthn Tene: That's _exactly_ what Zavolaj needs.
Tene: So yes :-)
22:03 cdarroch left
pmichaud jnthn: also, I suspect that you could turn your helpers into closures :-) 22:03
mberends jnthn: pong!
jnthn mberends: oh no Makefile fail! 22:04
mberends: namke is not at all happy about $(shell ... )
pmichaud: Yeah but in trait mods we don't have a clone.
mberends: I don't have enough Makefile-fu to really know what else to try there. 22:05
mberends: I can see what the aim is.
22:05 pyrimidine left
pmichaud jnthn: I think I have to refresh my .wrap memory to be of much help 22:06
jnthn pmichaud: OK
pmichaud: Anyway, I can best fix Zavolaj by making .wrap work sufficiently from trait_mod
tylercurtis O.o... you can have scripts inside block-quotes in HTML.
jnthn Can't you have scripts inside anything in HTML? :-) 22:07
pmichaud where does trait_mod invoke wrap, ooc?
jnthn pmichaud: Zavolaj has a trait_mod that currently does a pir::setattribute($routine, '$!do' thingy) 22:08
pmichaud: I'm looking to replace that with $routine.wrap(thigy);
pmichaud: It wouldn't actually call the original
pmichaud: In native call we just ignore the Perl 6 sub body. 22:09
22:09 alester left
TimToady sorear: there's already a parameter binding form of when: see S03:3616 22:10
tylercurtis jnthn: I suppose anything that allows inline. But it just seems that blockquote would have a specific exception: "you can have any block element, or scripts, in here".
jnthn huh, s03? :-)
22:10 jferrero joined
jnthn went looking in S04 :-) 22:10
supernovus May I request that someone with a proto commit bit add github.com/supernovus/temporal-utils to the modules list ? It's where I've moved the DateTime::Utils module providing strftime (and shortly, offset-in-seconds) 22:11
TimToady helps in grepping to know what it already looks like: when * -> $a, $b {...}
jnthn TimToady: oh, I was looking for "when ->" :-) 22:12
TimToady that would mean something else
that would be pattern matching with a lambda, and require another block after it 22:13
jnthn *nod*
TimToady: aye, makes sense
TimToady mind, that'd have roughly the same effect, if you put an empty block afgter
pmichaud jnthn: I can't think of any reason off the top of my head why assigning to $!do would no longer work. 22:14
jnthn pmichaud: because in !get_closure it does 22:15
do = clone self
Which assumes the original Parrot sub is being cloned
pmichaud okay, I'm just confused.
jnthn pmichaud: Unless by assign by mean like pir::copy 22:16
pmichaud I don't know nearly enough about Zavolaj or the wrap implementation to be of much help, I fear.
jnthn Rather than a setattribute on the $!do, which I guess is a bind
pmichaud: OK, let's step back from those.
pmichaud: Here's what I need to do.
pmichaud: We have some sub foo() { }
pmichaud: That compiles down to a Parrot Sub and we do !get_code on it to get the static code object, and !get_closure on it to get the dynamic one 22:17
pmichaud okay so far.
jnthn pmichaud: OK, so far wrap when somebody does foo() we need to not run the original Parrot sub
pmichaud: We need to run some new thing. 22:18
pmichaud so far so good. 22:19
jnthn OK, so my question is how do I specify that, when I make a call on foo() - the wrapper - then I should end up running some other Parrot sub instead of the original Parrot Sub?
22:20 Schwern left
pmichaud if I do &foo.wrap({ ... }), am I modifying the static code object or the dynamic one? 22:20
I think it must be the dynamic one.
cono Where can I find Buf class implementation ? 22:21
src/core/Buf.pm contain only a role
jnthn pmichaud: Potentially either. (more)
cono: There is just the role - it gets punned into a class when needed. 22:22
pmichaud: in the trait_mod, we are given the static code object.
22:22 justatheory left
jnthn pmichaud: Wrapping that should certainly affect all dynamic versions down the line. 22:22
cono jnthn: bug IO.read returns Buf.new
pmichaud I don't understand the trait_mod case. example or code, please?
cono but*

cono: And then calls the method on the class.
cono wow
jnthn: ic, thanks )

jnthn Still have to instantiate it ;-)
:-)
pmichaud: Did you follow the example? 22:26
pmichaud jnthn: I'm working through it.
cono cool
pmichaud in this case, I think that trait_mod:<is> should be called with the static code object
yes?
jnthn pmichaud: I believe it is being yes
pmichaud so .wrap should be replacing the $!do of the static code object
jnthn I think we decided it had to be that way during the refactors.
pmichaud: Yes, it is. 22:27
pmichaud okay
I think I see the fix
just a second
jnthn pmichaud: The trouble is that replacing the $!do in the static code object does not influence the $!do of the dynamic code object.
k :-)
pmichaud did you try changing 22:28
do = clone self
to instead clone the $!do of the static code object
(in !get_closure) ?
in this way, the parrot Sub continues to be the handle to get static/dynamic code objects, but the cloning always comes from the static code object 22:29
cono rakudo: my @arr = 1,2,3; Buf[Str].new(@arr).[0].WHAT.say

cono It's because attribute typing is nto working? 22:29
jnthn cono: Yes
pmichaud: I didn't - that was the line I mentioned a few screenfulls back, but with little idea if I was being sane back then. :-) 22:30
pmichaud: The fact you've got there too suggests that maybe yes :-)
pmichaud jnthn: I suggest try that and see what happens. I *think* it should work.

jnthn pmichaud: Compiling. 22:31
22:31 jaldhar joined
tylercurtis cono: Buf stuff probably will not work anything like you expect for Buf[Str]. You want to pass in some kind of integral type to Buf. 22:32
pmichaud jnthn: have a diff I can look at real quick to see if I see anything odd? 22:33
(a diff for !get_closure)
22:34 gbacon left
jnthn pmichaud: gist.github.com/485246 22:34
tylercurtis Is Buf supposed to be a role or a class?
pmichaud jnthn: yeah, that looks reasonable. 22:35
jnthn tylercurtis: It's type-parametric I think, so role is sane.
pmichaud jnthn: I hope that works. It doesn't set off alarm bells in my head, and I agree that the do = clone self isn't going to work out.
22:35 zamolxes joined
pmichaud just make sure whatever you stick in the $!do is reliably clone-able :) 22:35
jnthn pmichaud: looks promising 22:36
tylercurtis S32/Containers says class, but S02 says role.

jnthn pmichaud: With that patch, Zavolaj works again without changes. \o/ 22:37
tylercurtis jnthn++, pmichaud++ 22:38
jnthn pmichaud++ # thanks! :-) 22:39
.wrap doesn't quite work but I know .wrap is generally a bit busted anyway
22:39 colomon left
jnthn So that's maybe not even related 22:39
pmichaud .wrap should be fixable along the same lines now, though.
jnthn pmichaud: Right.
pmichaud anyway, glad to help on short notice. 22:40
jnthn pmichaud: Will spectest and push if this works.
pmichaud +1
jnthn++
jnthn er, if it passes
:-)
Anyway, that fixes Zavolaj up, hopefully.
pmichaud as I said, I can't think of any alarm bells for it.
so, I'm pretty comfortable with the change.
jnthn pmichaud: Yes, was a little less than keen to touch that code without running things by you first though. It's still quite new. 22:41
pmichaud it's also good for me to know that change was made (and why, and what it means overall)
I didn't have the use case in my head until this conversation :)
it's snack time here, so I'll bbiaw 22:42
jnthn kk
cono tylercurtis: What integral types besides Int? 22:43
tylercurtis cono: mostly the native types, I think.
jnthn Aye
int8, int16, etc. 22:44
Not implemented just yet.
tylercurtis jnthn: Although probably uint8, uint16 is usually what is desired for Buf.
cono :(
jnthn tylercurtis: aye 22:45
I expect to implement them in the next few months.
cono pack needs Buf, Buf needs integral types and method types which are not implemented... 22:46
ok, I guess I can emulate pack by doing ~|, ~& ... 22:48

jnthn cono: If you're interested in pack, also talk with masak, who is very interested in working on that too. 22:51

tylercurtis Is there a "is required" or similar trait for attributes? 23:48
23:51 Schwern joined
tadzik I don't think so 23:51
you can have $.attr = die "attr is required"
hmm, I've ported File::Find but the usage is a bit different than Perl5's one 23:54

tylercurtis: ever used Perl 5's File::Find?
tylercurtis tadzik: No; I haven't done much Perl 5 at all. 23:56
tadzik I see
23:57 Psyche^ joined
cono I used much, but never used File::Find :) 23:57
tadzik :) Wanna share thoughts? 23:58
cono about? 23:59
tadzik Perl 5's File::Find fires a callback on every file it found. The callback takes no arguments, but can get the current filename, path, and directory name from external variables. My version just passes the whole path to the callback
also it does not chdir(). I wonder how bad it is, and what advantages does original approach have
