masak "This synopsis summarizes the non-existent Apocalypse 9, which discussed in detail the design of Perl 6 data structures. It was primarily a discussion of how the existing features of Perl 6 combine to make it easier for the PDL folks to write numeric Perl." -- S09 08:57
I've always been a bit curious about how this non-existent A09 would look :>
today is not the day, but maybe some day I'll attempt to write it, just to see what it looks like. 08:58
naturally, it would have to contain (a) TimToady's "voice" and jokes, (b) understandable mis-features that were since fixed, some of them historical, some of them not. 08:59
(c) later corrections to these misfeatures, explaining how things are now in S09 09:00
(d) discussions around the appropriate RFCs
(but probably not focused on that, since by the time of A06 and A12, Perl 6 had already established itself enough that "ok, here's what we'll do" was the main thrust of an apocalypse) 09:01

masak maybe you've been unfortunate enough to see a lot of shoddy Perl. if you've seen enough beautiful Perl, your perspective changes.

noface Flavour of the month in terms of usage. Hipsters wanting to use new libraries and so on, so forth 12:00
DrForr Shrug, you mean like new frameworks like Dancer and Mojolicious? You're right, that's *so* last month. 12:02
12:03 rindolf joined
masak wow, I had honestly not heard Perl called that before. 12:03
noface I have no idea, as I don't use Perl. Like I've said before, I use python for scripting, and C/Haskell/Lisp for everything else. GLSL for shaders, though I have contributed to HLSL projects since I dualboot windows. 12:04
masak maybe you meant to troll #ruby?
noface Ruby and Perl are constantly at war with each other, I know that muhc
much*
masak your knowledge does you credit. 12:05
noface Still, I'm not too fond of high level languages like Perl. For that, I'd much rather use python, as it's far more pleasant to use.
profan who joins a language channel just to say they don't like the language though?
noface I was merely testing my theme!
masak profan: we don't get a lot of them, for sure. but they do exist.
DrForr profan: Boring trolls.
noface Hardly a "troll" 12:06
profan noface: the "i detest perl" part though wasn't really necessary was it though? :P
but i digress
masak noface: I use both Perl and Python. I find Perl a lot more pleasant to use, for several reasons. people's tastes diverge.
DrForr You're right. Minor nuisance would be a better description. Maybe go back to #python and practice somewhere first? 12:07
noface Well, Perl is objectively less intuitive, which is slightly off putting when all you want to do is write a high level script
masak he's not a very good troll, I agree.
needs practice.
but I admit I laughed at the "testing my theme" excuse :D
noface Back to python? Never been there, never will be. Barely use it anyway. 12:08
DrForr Good to know that intuition is so objective, I'm sure philosophers worldwide will cheer.
noface It's not an excuse. I was testing some themes and couldn't find a channel to test them on (would rather not annoy my home channels!)
masak well, you annoyed a very agreeable channel instead. 12:09
profan Maybe he redefined what objective means? He does like C after all, them there "macros" and all ;)
DrForr I fail to see how joining a random channel to chatter at it is considered a "theme".
masak it is if the theme is trolling...
noface I said "test" and Masak immediately greeted me
profan I assume he means his client's theme
masak noface: how dare he!
noface Profan is right
nwc10 test? 12:10
DrForr I assume I don't care. *plonk*
masak nwc10: hi! \o
profan nwc10: test!
masak profan: hi! \o
profan masak: hi :D
masak :D
noface Very well. What are you guys working on?
masak there's a compiler called Rakudo. a lot of work goes on that. 12:11
but also the underlying VMs (JVM and MoarVM) and specification/documentation work.
this year is a big year for Perl 6.
DrForr Tracing a segfault in a perl6 readline module while setting up a Redis cluster.
12:12 tinyblak joined
profan is writing a toy language and compiler to learn P6 12:12
masak last time I had time for Perl 6 I was tinkering with scripts and old modules of mine.
DrForr profan: Check out perl6-ANTLR4 on github for ideas :)
andreoss profan: don't forget to put it in perl6-examples
DrForr Oh, yeah, I probably should add that to the module list. 12:13
profan DrForr: nice, thanks
12:13 tinyblak_ joined
profan it's pretty hard to find whats out there for perl6 already sometimes 12:13
masak yeah, it's a tough problem to crack :/
DrForr I'm almost done writing the AST, which should make an ANTLR => Perl6 grammar translator straightforward, with the exception of a few edge cases. 12:14
profan It's pretty interesting to see how different the attitude is in certain communities surrounding programming languages 12:15
noface profan: You mocked C a few minutes ago, but knowing C is very useful, especially when you want to branch out to GPU programming, like writing shaders for instance, since HLSL and GLSL both look a lot like C.
profan noface: There are valid reasons to mock every language, I like C myself, but that doesn't mean I can't criticize it, quite the opposite
masak I believe C macros can be used for good. MoarVM's use of them is a nice example of this. 12:16
profan If one is comfortable in their choices of tools, you should be well versed in both the pros and cons! 12:17
12:17 tinyblak left
masak but I also believe there are macro systems which help you a lot more and which are safer. 12:17
noface And if you know C to a reasonable degree, you most likely know some assembly as well (it actually makes pointers considerably easier to understand and use since you know WHY they were created in the first place)
arnsholt Yeah. You can do good things with C macros, it's just that they go out of their way to make it hard to do so
DrForr One of my backlog projects is to snarf enough of the existing C parser to write a quick C=>P6 nativecall converter.
Sort of like the old h2xs but with less cruft :) 12:18
arnsholt Yeah, it's on my list of awesome things too
Just be warned: There's a whole army of dragons lurking in there 12:19
DrForr I assume the pun was intentional.
profan the best puns are unintentional 12:20
arnsholt Not sure which pun you mean, so not intended, no =)
profan arnsholt: compilers... dragons? :P
DrForr That one, yes.

noface Depends, what would you like to do? 12:23
I am in the process of fixing MPDN's (media player dot net) chroma scaler, since it upscales each chroma channel individually before merging them, instead of merging them AND THEN upscaling 12:24
DrForr Offloading matrix calculations, nothing actually screen-visible.
noface Which incurs a large performance penalty (80-100%)
12:24 tinyblak_ left

PerlJam DrForr: are you outputting your Match object for debugging purposes? 14:47

DrForr <facepalm/> 14:49
masak Woodi: nope, not La Femme Nikita. :) 14:50
DrForr Okay, I'm guessing that the rationale was that ... displaying nesting and quoting on a nested data structure would encourage people to use 'say' for simple serializing rather than resorting to a proper module? 14:54

masak "warnocked - This lemma will never be explained." -- a case of trying to make a joke but ending up frustrating whoever was looking for information, methinks. 19:09
and I agree about the quotes. most of those quotes around links should just go away. no need even for <i>...</i> 19:10
wow, the `ufo` project is so old it has a non-Markdown README! 19:14
despite all the fun I had writing that README file, my favorite sentence nowadays is one that was added later: "My friend Ingy, who has lots of prior experience with alien technology [...]" :P

retupmoca masak: I'm building a new markdown module: github.com/retupmoca/p6-markdown - can I steal the Text::Markdown name from you, or would you prefer that both modules are in the ecosystem? 20:35
masak retupmoca: if you exceed what my Text::Markdown already does, then feel free to steal.
[Coke] Or you could test that having two modules with the same name works as expected. :)
20:36 brrt left
masak or that. 20:36
'night, #perl6
retupmoca is that actually supposed to be supported now? 20:37
retupmoca still needs to get up to speed on all the CompUnitRepo changes
if same-name-different-auth is supposed to work, or can easily be made to work, I'll just do that 20:38

timotimo neat :) 21:00
do we have anything to track exceptions and such, btw?
is there any way to get something like a "debug overlay" into a H:S:* powered program? 21:01
tony-o_ timotimo: i'm building that into the perl6-hiker app i'm working on 21:08
timotimo ooooh, you're already up to that? :D
tony-o_ mvc framework
otherwise, right now it just catches and .says
github.com/tony-o/perl6-hiker/tree/master/usage 21:11
that's kind of the syntax i'm going for
similar to mojo but more concise
timotimo why is it "$app.bind; $app.listen" instead of "$trail.go-hiking"? :)
tony-o_ haha, because it's still really rough atm :-) 21:12

AlexDaniel how can I write a comment on rt.perl.org without having an account? It said that all I have to do is just write an email with the bug id in the title, and it said that just replying to this message should work. And that's what I did. But my comment did not appear 23:11
