timotimo nbdsp: you do know of DBIish though, right? 02:00
ugexe it doesnt work with the binary data he needs to use 02:01
because it uses mysql_query

jnthn No, it's the type that inlines a VM-level idea of string into a Str, which has to have a P6oaque REPR so you can mix into it. 06:31

nwc10 what's the state of Fedora's transition from yum to dnf?
brrt what is dnf

but i guess change is what we get
nwc10 I liked yum
xiaomiao I wonder if dnf has removed the massive stupid that yum carried around
so much singlethread. many exlusive lock. wow.

brrt now that we are on the topic of python. who else thinks the 'new string formatting' is not an improvement 07:04
masak brrt: I'm a fan of it. I think the old sprintf syntax is arbitrary and weird. 07:05
brrt: I think the '{}' things have visual-pillness going for them.
but other than that, see my latest macro post: "All templating syntax sucks." strangelyconsistent.org/blog/macros...eholdeeers 07:06
brrt i thought i read that, yes
masak (masak's Deplorable Truth About Templating Syntax) 07:07
nine .tell nbdsp Inline::Perl5 is passing binary strings from Perl 5 to Perl 6 as CArray[int8] followed by manually copying to a Buf element by element. Sounds horrible but at least it works until NativeCall gets improved.
yoleaux nine: I'll pass your message to nbdsp.
brrt that is true, but i'm very much used to sprintf syntax :-)
arnsholt I'm in a similar spot. I'm pretty sure that the new syntax is better, it's just that I know the printf directives too darn well! =) 07:08
masak brrt: there you go then :) you've abstracted away the pain.
brrt it does work really well for mapping dict-like things to strings, that i grant 07:09
(the new syntax)
masak and objects are dict-like :) 07:10
in that sense
brrt sufficiently dict-like? i'd have to test
arnsholt Python objects are very dict-like, though =)
Extremely dict-like, even =)
brrt not enough to automagically map 'm 07:11
arnsholt object.__dict__ =) 07:12
nwc10 masak: interesting. I'd not considered the relative timescales of debian release versus Python 2 EOL 07:13
arnsholt Is the object namespace as a dict. You can turn that functionality off, though; but by default, all Python objects are just dicts
masak nwc10: thought you might like that one. 07:14
nwc10 I did

nine masak: I wonder what you think about Petal's solution to sucky templating syntax: metacpan.org/pod/Petal 07:22
masak: since out of band signalling sucks, it avoids it altogether.
07:22 mohij joined 07:23 lizmat joined
masak nine: yeah, I had that same thought when I was re-reading my templating blog post just now. 07:23
nine: I personally consider XML namespaces/attributes to be one of the cleanest solutions to templating. 07:24
it *is* still out-of-band, but more on a semantic level instead of a syntactic one.
nine Maybe there's something to learn there? Though of course, this solution limits the things you can do to a somewhat sane subset which may not always be enough. 07:25
RabidGravy yeah it's a nice style and plays well with the tools the web developers use
masak nine: yeah, the horror of being limited to a somewhat sane subset! :P
nine: my go-to example of this is Genshi. genshi.edgewall.org/ -- but it's the same basic idea. 07:26
nine: little known fact is that AngularJS can be used in the same way, with XML namespaces.
RabidGravy I was just about to mention that 07:27
masak I know of no-one who uses it in practice, but I don't doubt someone is. 07:29
that seems to be the way to placate angry HTML validators, for example.
RabidGravy I think I have somewhere
maybe not 07:31
thought it was in github.com/jonathanstowe/example-a...tbook.html
nine masak: little known is also that even Petal does allow $variable substitution. I hate that this feature is there, but I don't dare to remove it. Maybe there's a learning opportunity here, too. Have a sort-of-out-in-band sane subset limited solution that looks nice and additionally provide some neccessarily ugly way to do all the really nasty things?

masak new concept: many popular scripting languages have a "piñata", another language adherents tend to regularly ridicule or hate on a little. 08:46
Python's piñata is Perl. Perl's piñata is PHP. 08:47
Perl 6 has largely avoided making Perl 5 a piñata, thankfully.
nwc10 is PHP grown up enough not to need one?
(unlike Python and Perl) 08:48
DrForr It's not the language's maturity, it's the user's :/
moritz maybe PHP developers don't know enough about other languages to hate them? SCNR
nwc10 I like masak's idea. It's just that it seems to have a curious implication 08:49

DrForr And in County Kerry it's one poor sot.

nwc10 nine: ah OK. I also don't have an answer for whom the Burganlanders make fun of, but it's been suggested that it's the Viennese 08:56

grondilu damned when I have to write some P5 code, I feel so confused. Like, how do I write the equivalent of for ^Inf -> $n {...} ?? 15:02
for my $n ($something_here) {...}

maybe for (my $n = 0; ; $n++) ?

[Coke] It's usable today. If you have a specific use case we can probably tell you if we do that well already. Anything we can't do off the shelf, we can probably do with Inline::Perl5
masak prime-time means different things to different users.
psch ...and masak illustrated one of the viewpoints 21:04
DrForr [Coke]: Yeah, it's not the right word, but it's late here and I can't quite sum up my impressions in a convenient Twitter-sized commuique'.
psch if "primetime use" means "production ready", then it's a question of "what does that mean?"
DrForr And that's why I was after his definition of 'prime-time'. It's already available in RPMs, though somewhat outdated.
21:05 raiph left
psch the other would be taking "primetime use" to mean "everyone *should* use it", which is obviously overly idealistic, because it assumes preference doesn't matter, and as such this viewpoint should be discarded 21:06

riceandbeans so perl6 is now a jvm language in the only actively developed implementation, according to wikipedia
masak yep.
though it's not jvm-only. 21:09
[ptc] maybe the wikipedia page should be updated and MoarVM metioned as well
riceandbeans well, jvm or 'moarvm', but I've never heard of the latter and wikipedia says that it's slower

masak moarvm is the recommended default backend at this point.

[Coke] MoarVM was built specifically for what Perl 6 needed, so, unless you've touched perl 6 before, it's not surprising you haven't heard of it. 21:17
riceandbeans why abandon parrot though? 21:18
and why flock to jvm?
21:19 lizmat left
[ptc] jvm is a widely-used technology, and makes asynchronous stuff easy to implement, from what I understand 21:19
timotimo one of the big reasons to build a port to the JVM was that the jvm had battle-tested concurrency already 21:20
Su-Shee riceandbeans: there's a very very long article about that..
[Coke] Also, targetting the JVM lets us get our foot in the door in some corporate environments (like mine)
timotimo rakudo, our main implementation, was aimed towards running on multiple different VMs at a somewhat early point 21:21
and porting to the JVM was an exercise in that, so to speak
[ptc] Su-Shee: do you have a link?
[Coke] basically, moarvm took the lessons learned from parrot, and from perl 6 development. it's goal was to do what perl 6 needed and nothing else, and that hadn't been parrot's goal for a lot of its formative years.
timotimo but since we have jvm interop, we can potentially tap into a very big library of modules through the JVM
i haven't seen terribly much in the way of examples, though
[Coke] parrot was trying to be a good backend for a bunch of different languages. (And it's doing OK at that, near as I can tell)
someone just did a bunch of good work on JVM interop. 21:22
vendethiel timotimo: I know a few friends toyed with it, but executing p6 code from the jvm was still insanely slow for now :)
timotimo mhh
riceandbeans most perl people don't like the JVM
Su-Shee hmm lemme look
timotimo i suppose that's their loss
riceandbeans it's like trying to alienate your base for the swing vote 21:23
Su-Shee riceandbeans: that's nonsense. also, any other language has a jvm implementation, it's an extremely smart move
riceandbeans in my opinion
[Coke] anyway, welcome to the channel. Please hang out and give the evalbot a whirl, and grab a copy of rakudo 2015.03. 2015.04 is almost out.
timotimo being able to deploy stuff to the JVM lets you get into lots of places
though with rakudo on jvm, you need to deploy onto a device with lots of ram, but that's always the case with a jvm ;)

psch i have memories of my toes being bitten and clawed at when living with cats 21:27
riceandbeans oh no, my walls
Su-Shee: I bought them markers, and they turned my walls into murals
psch i'm also reminded that i should sketch out and probably implement a few more jvm-interop bits... 21:28

nbdsp_ Greetings! Due to inability of DBIish module to work with binary data, I was advised here to use DBI from Perl 5 as follows: use DBI:from<Perl5>; my $dbh = DBI.connect(... However this produces an error: "Don't know how to load code from Per 5". Are there some additional declarations or modules needed for using Perl5 code? 21:35
*Perl 5

RabidGravy Inline::Perl5 I think 21:38
skids nbdsp_: I think :from<Perl5> was just made to work today?

timotimo can't you use Foo:from<Perl5> if you use Inline::Perl5 before that?
nbdsp_ I don't use Inline::Perl5. Is it needed with that feature? Or I need to reinstall Rakudo for using F;;::from<Perl5>?l 21:43
*Foo::from<Perl5>?
21:43 rurban_ left
skids Either reinstall or use Inline::Perl5 but you will need to intall Inline::Perl5 in either case. 21:44
nbdsp_ Thanks. Will install Inline::Perl5 and if it doesn't work, will reinstall Rakudo. 21:45

timotimo now that we have a fast analysis tool for profiles, maybe someone with a machine with loads of ram could run a core setting compilation with --profile-compile (and probably also --optimize=off to reduce the profile size and ram usage even further)? 21:53
is there somebody here with a machine that has 32gigs of ram or something? i have no idea if that's enough %)
i wouldn't dare run it on hack.p6c.org 21:54
vendethiel :from<Perl5> worked before AFAIK, but wasn't in core 21:56
RabidGravy parse is twenty seconds quicker than it was for some reason 21:58
flussence 20?!
riceandbeans xkcd.com/1513/ 21:59
timotimo i'll try if 8 gigs of ram and 10 gigs of swap will be enough locally 22:01
RabidGravy bizarre
timotimo RabidGravy: that can happen if you forgot to optimize your moarvm build. in fact, parrot used to default to --optimize=0 if you didn't pass --optimize to its configure script, which confused the hell out of me one day
flussence timotimo: got a compilation command line I can blindly copy and paste? ;) 22:03
timotimo i just closed that tab
flussence (I wonder if 8 gigs of RAM and a gigantic /dev/zram0 swap would work...) 22:04
timotimo just delete CORE.setting.moarvm and "make", it'll give you the line i mean
it's the one following "this is going to take a long time"
flussence righty
timotimo thank you!
the resulting profile-*.html should gzip very nicely
AFK for a bit
.o( of course after copy-pasting you'll need --profile-compile rather soon after the "perl6.moarvm" ) 22:05
22:06 raiph left
flussence my fast server's currently crying under the load... maybe I'll try it on my slow one (which has a big fast SSD, so tons of real swap ought to not hurt) 22:16
timotimo i'm at 5.5 gigs of swap used and growing 22:18
flussence 9GB here :D

timotimo damn :\ 22:31
hm
i wonder ...
ah, hehe 22:32
whenever the profiler reaches 4096 "pieces" of string added to its list, it joins all the pieces together and the result becomes the new first piece 22:33
we should be able to do a bit better than that
flussence maybe it'd be better to spit it straight out to a file... 22:34
I'll give it another shot in the meantime, hopefully 48GB of swap will be enough... 22:35
(wait... how are we gonna *load* this profile?) 22:38
timotimo the profile itself will be much, much smaller 22:46
i think it'd be enough to keep a list of "megachunks" around and instead of joining them just print them out to the file one by one 22:47
but i should go to bed now
if you want to hack that, it lives in nqp's repository under src/vm/moar/HLL/Backend.nqp
nbdsp_ Reinstalled Rakudo and Panda gives the following error on installing Inline::Perl5 or reinstalling Panda: $ perl6 bootstrap.pl ==> Bootstrapping Panda ===SORRY!=== Unsupported serialization format version 13 (current version is 15)
timotimo you have some old precompiled files lying around, i'm afraid
it's kinda shitty that it doesn't give you a filename, though 22:48
nbdsp_ make clean?
timotimo oh 22:50
can you use rebootstrap.pl instead?

flussence is watching this --profile-compile via strace... mmap()s 6 or 7 quarter-GB chunks spaced 0.5s apart, thinks about it, then throws them all away and repeats 23:29
It's getting *somewhere*, just very slowly and oddly
vendethiel flussence: it's solving the halting problem, just you wait! 23:34
flussence I think tweaking the to-json code is probably gonna be a better approach, I'll try that instead. 23:37
