03:14		hulu	what's means substr($string, $offset) = "gilism ain't for wimps";
03:15		geekosaur	nothing these days; it's substr-rw instead of substr.  but lvalue substr replaces part of a string.  (from $offset to the end of the string is removed, then the assigned string put in its place)

03:23		geekosaur	that is out of date; substr-rw is a recent change
03:24		sorear	geekosaur: some basic maybe?
03:24		geekosaur	huh?
03:25		geekosaur	(yes, I know basic's MID$ did it that way)

03:27		swarley	well, that's part of it
03:27		swarley	But that would seem as if the capture is wrong..

03:31		swarley	Oh. Because quantified_atom is the only thing actually used
03:31		swarley	actually no
03:31		swarley	Because quantified_atom doesn't consume that character..
03:33		geekosaur	hulu: in fact that perl 6 snippet must be pretty old... "Pugs is da bomb"?  these days pugs only supports about a third of the perl6 spec...

03:50		sorear	sounds like your perl 5 is incomplete
03:51		swarley	holy shit, it's using an ancient version
03:51		sorear	how ancient
03:51		swarley	v5.8.8
03:51		sorear	Test::Harness was first released with perl 5
03:51		sorear	(.000)
03:51		swarley	This is perl, v5.8.8 built for msys
03:52		sorear	according to module::corelist anyway

04:00		hulu	what's means of X** 2
04:01		swarley	Im thinking that it's a variable for that loop..
04:01		geekosaur	no, that's a metaoperator
04:01		swarley	No clue what that is
04:01		geekosaur	X is cross product; so it returns every possible combination of the left side ** the right side
04:02		swarley	ah. So it's like a map?
04:02		geekosaur	1..10 X** 2 means 1**2, 2**2, ..., 10**2
04:02		geekosaur	vaguely
04:02		geekosaur	but if the right side weren't a scalar...

04:10		sorear	do you have a working c compiler on the machine?  is it the same one your perl 5 uses to build extension modules?
04:10		sorear	parrot lifts a lot of configuration from the p5 extension builder
04:11		swarley	I moved into a cygwin environment, and the perl installation is working fine now.
04:11		swarley	I suppose I'll reinstall gcc
04:12		sorear	can you install extensions on the perl env though

11:12		nwc10	source level should be comprised in between '1.3' and '1.6' (or '5', '5.0', ..., '7' or '7.0'): 7.0
11:12		nwc10	which part of 7.0 don't you understand?

11:38		moritz	gcj not telling you straight that it doesn't support version 7.0, but produces some bullshit error
11:40		nwc10	it's gcj-4.4. I think it's two versions beyond what gcc.gnu.org say they support
11:40		nwc10	and I'm not sure if Debian are going to fix their package
11:41		jnthn	According to wikipedia, "As of 2009 there have been no new developments announced from gcj."
11:42		jnthn	And http://gcc.gnu.org/java/ makes it look very...stable.
11:42		nwc10	oh boy yes.
11:42		nwc10	even Module::Build is more active than that
11:43		jnthn	http://stackoverflow.com/quest[…]compiler-gcj-dead says it doesn't do the nio stuff

13:40		swarley	Like.. Exiting the shell?

13:42		swarley	oh
13:43		masak	yes, exit() is spec'd in S29 for Perl 6.
13:44		masak	but nqp is a non-strict subset of Perl 6, so it's not clear to me that it's part of nqp.
13:44		masak	that said, it would be nice, of course.
13:44		swarley	I just assumed, since that's the only way I've seen to exit interpreters properly
13:44		masak	^D
13:44		masak	^C
13:44		swarley	Well yeah. But I mean programmatically
13:45		swarley	I used EOF to get out of the REPL when exit wouldn't work
13:45		swarley	But I generally don't like using it
13:45		masak	'exit' wouldn't work in nqp even if the subroutine were defined, unless it were special-cased.
13:46		masak	you'd have to write it as 'exit()'.

13:59		thundergnat	Is there a way in Rakudo to augment  a parent type at run time and have the augmented method available to child types automatically? I know that used to "work" but it's entirely possible I was (ab)using unspecced behavior. :/

14:44		nwc10	gah, $N
14:44		nwc10	anyway, I *have* tweaked it locally
14:44		nwc10	but nqp-jvm ignores @ARGS, it seems
14:49		arnsholt	Hmm. Looks like my refactor broke something
14:50		arnsholt	That's an annoying thing with floats. It less obvious what's wrong when they have weird values
14:53		nwc10	not exactly comparing like-with-like, but for various fibonachi example scripts, NQP on the JVM is 8 times faster than on Parrot
14:53		nwc10	and runs in about 60% of the time of Perl 5
14:54		moritz	woah :-)
14:54		arnsholt	Nice!

15:03		nwc10	a) I don't know the syntax

15:04		arnsholt	In that case native types aren't a good idea, yeah
15:05		arnsholt	Instead you can say that not only is it a bit faster than Perl 5, it also handles arbitrary precision =)

16:06		arnsholt	He seems like a hoopy frood
16:06		masak	I told him I was a big fan of his, so the signature says "Carl, it was great to see you here! Keep your hands to yourself. -- Ovid" :P
16:06		timotimo	:D
16:06		arnsholt	=D
16:06		timotimo	that's cute. unless you creeped on him ;)
16:06		masak	don't think so.
16:07		masak	it was all in jest.

16:07		masak	as evidenced by http://strangelyconsistent.org[…]roles-are-awesome
16:12		timotimo	that reminds me that i haven't looked at druid again for a long time. i think the last time i did i was tripped up by not really understanding new and BUILD properly
16:14		masak	Druid certainly predates a lot of BUILD changes in Rakudo.
16:15		timotimo	maybe i just need to write something myself that uses different aspects and combinations of BUILD and new in a context that makes sense
16:15		timotimo	but try to come up with something like that! ;)
16:17		masak	short rule: BUILD is for initializing your attributes at object construction time. define your own 'new' method when you want a 'new' method with a nonstandard signature.
16:18		arnsholt	But if you write your own new, you have to bless as well, right?
16:18		timotimo	right. i think what i didn't quite understand was how to pass things from the new method to the BUILD method
16:18		timotimo	arnsholt: i believe so
16:19		timotimo	in controlling lazyness, maybe "my $ls = lazy { $expansive_computation };" meant to read "expensive" instead?
16:19		masak	arnsholt: yes.
16:19		timotimo	but i think both words could be correct in this case
16:19		masak	arnsholt: constructors (by definition) are methods that .bless
16:19		arnsholt	Yeah, that's what I thought
16:19		masak	arnsholt: I wouldn't ever create a method 'new' that isn't a constructor.
16:20		arnsholt	Definitely. That'd be a recipe for disaster I think
16:20		masak	it's mroe common than people think to have non-'new' constructors.
16:20		masak	MyGrammar.parse, for example.
16:20		masak	more*
16:20		arnsholt	And DBIish.connect if memory serves
16:20		timotimo	how about a new method that returns something from a cache? would that be considered bad, because it's not a "new" object?
16:21		timotimo	submethod new($foo) is cached { ... } ;)
16:21			thundergnat left #perl6
16:21		masak	timotimo: depends on the other invariants on the class, I'd say.
16:21		masak	feels a bit odd, but not necessarily morally wrong.
16:22		timotimo	mhm. for an immutable class, it's probably not problematic, but for a mutable one it might rub people the wrong way
16:22		arnsholt	Heh. "Morally wrong" ^_^
16:23		timotimo	is ; in parameter lists of calls a thing? i don't think i ever really understood what it's for. is it to prevent lists passed as arguments from being flattened together by the , operator?
16:24		timotimo	but i thought you needed | for that?
16:24		timotimo	(me with the non-questions again!)
16:24		arnsholt	I think it interacts with multidispatch somehow
16:25		arnsholt	(The stuff after ; isn't considered when dispatching?)
16:26		jnthn	Yes, that.
16:26		jnthn	It makes what's beyond the ; not be consider by the multi-dispatch candidate sorting thingy.
16:27		masak	do we still have ;; ?
16:27		masak	(or did I dream that?)
16:31		jnthn	I...have some memories of something like that... :)
16:32		jnthn	Is that the "produces separate candidates" thing?
16:33		timotimo	like two alternative signatures that both cause the same candidate to be invoked?

16:55		arnsholt	jnthn: Oh, one thing. Previously, CArray returned NULL for out-of-bounds, but that's not possible anymore. I guess returning a zero value is the best we can do?
16:56			vividsnow joined #perl6
16:57		jnthn	arnsholt: What were we doing on out of bounds before?
16:57		Celelibi	Well. Looks like there is no image lib for perl6 yet.
16:58		arnsholt	The old approach returned a pointer to the data, so we returned a NULL pointer
16:58		arnsholt	But there's no pointer-passing anymore, so that can't happen anymore
16:59		jnthn	arnsholt: Yeah, I meant what happened in response to the null pointer?
17:00		jnthn	arnsholt: If it was that the op threw an exception, we could maybe do it right in the REPR...
17:02		arnsholt	jnthn: Oh, right

17:04			grondilu joined #perl6
17:04		arnsholt	Hmm. Looks like noone did any bounds checking, so we may have ended up segfaulting...
17:04		arnsholt	Err, s/bounds/null pointer/
17:04		grondilu	Was masak's talk at FOSDEM recorded?
17:08		arnsholt	jnthn: I don't think that particular code path had ever been tested, TBH
17:08		arnsholt	Going by the code in master, I'm pretty sure it'll try to read from a NULL-pointer
17:09		arnsholt	There's an out-of-bounds test, but that one gets a pointer object, not a native
17:11		jnthn	Ah.
17:11		jnthn	Guess we get to not segfualt then ;)
17:12		arnsholt	In that case I guess we can do whatever we want to, since there's no (sensible) backwards compat to worry about
17:15		jnthn	:)
17:15		jnthn	Yes, I'm happy not being backward compatible with segfaulting.

17:26		rindolf	TimToady: I hope this trend will continue.
17:26		* TimToady	too
17:26		TimToady	Celelibi: for some things, sure
17:26		jnthn	Celelibi: Depends what you want to use it for.
17:27		* jnthn	has successfully used it for various stuffs :)
17:27		rindolf	Celelibi: depending on how usable and what for.
17:27		Celelibi	I mean: can I move from perl5 to perl6?
17:27		rindolf	Celelibi: also see Niecza (sp?)
17:27		rindolf	Celelibi: you shouldn't "move".
17:27		TimToady	Celelibi: you can start using both
17:27		rindolf	Celelibi: you should learn it and use both.
17:27		Celelibi	Well, currently I can't really use Perl6 since it really lacks modules.
17:28		TimToady	programming in Perl 6 will improve your Perl 5 as well
17:28		rindolf	Celelibi: do you mean something like CPAN?
17:28		Celelibi	yes.
17:28		TimToady	Celelibi: what you mean by "usable" is that everyone else has done the hard work for you :P
17:29		Celelibi	precisely. :)
17:29		TimToady	well, we're all working very hard around here
17:29		Celelibi	Is there any way to use perl5 modules from a perl6 code?
17:30		rindolf	Celelibi: well, feel free to write a new Perl 6 module or enhance an existing one.
17:30		rindolf	Celelibi: CPAN was not built in a day.
17:30		rindolf	Celelibi: and we now also want to enable Perl 6 to make use of the Perl 5-based CPAN.
17:30		rindolf	Celelibi: there may be Inline::Rakudo on CPAN.
17:33		TimToady	Celelibi: there is a way to use some modules, depending on how fancy you need the API to be; this will probably improve greatly over the next six months
17:34		rindolf	TimToady: BTW, have you studied Esperanto?
17:35			spider-mario joined #perl6
17:35		Celelibi	Well. I currenty need to write a few scripts manipulating images. And I thought "hey, why not let this be an exercise to practice perl6?"
17:35		TimToady	nope, did a bit of Lojban, saw the error of my ways
17:35		Celelibi	But I don't think I'll do this if that means porting Image::Magick to perl6.
17:35		rindolf	TimToady: ah.
17:35		rindolf	TimToady: I see.
17:35		rindolf	TimToady: BTW, don't you want to learn Hebrew?
17:36		TimToady	I want to learn every language, but I have only one brane, and more importantly, only 24 hours in a day

17:39		Celelibi	Who never thought about a way to plug his brain to a computer? :)
17:39		jnthn	arnsholt: Believe so, yes.
17:40		arnsholt	Excellent
17:40		arnsholt	It's the proper thing to do I think, but always good to get a second opinion
17:43		rindolf	Celelibi: well, maybe it dates back to the hallucinations of the Jewish prophets.
17:43		rindolf	Celelibi: who met God and his angels.
17:45		rindolf	Celelibi: BTW, לנבא in Hebrew did not originally meet to predict the future (that was a mistranslation in LXX which also influenced Jewish thought) but rather it meant to hallucinate voices of "Jehuvah"/"The Owner"/other Gods for guidance
17:45		TimToady	well, I believe that God will choose to speak through whatever medium is currently in vogue :)
17:45		rindolf	Celelibi: at least that's what I understood from http://en.wikipedia.org/wiki/B[…]_%28psychology%29
17:45		TimToady	nowadays it's more likely to be the Internet :)
17:46		rindolf	TimToady: I think everyone can speak as God sometimes.
17:46		TimToady	which is a kind of mass hallucination :)
17:46		geekosaur	reality is a mass hallucination, by some arguments
17:46		TimToady	but a very nice one, in spots
17:47		* geekosaur	wonders how many religions have a Prime Hallucinogen
17:48		Celelibi	What if we're all bare-flesh connected to a single huge computer simulating the world?
17:49		TimToady	well, that's kinda what the holographic principle is claiming in physics :)
17:50		TimToady	as long as the medium I'm swimming around in supports creativity, I don't mind if there's a better Creator

17:53		rindolf	TimToady: at least I think.

18:43		clintongormley	i also saw the comment in irc about the nqp fibonacci running fast :) i'm hoping that applies to the rest of p6 too
18:44		* clintongormley	is working in a java shop now, and the Perl jokes are becoming a little tiresome...

19:03		perigrin	swarley: I have no official position but I think it's safe to say "Heck no! Go for it!"
19:03		arnsholt	I'd think it's a pretty cool thing to do =)
19:04		swarley	For anyone that isn't aware, YARV is MRI Ruby's VM
19:04		* perigrin	guessed but wasn't sure.
19:04		arnsholt	Oh cool. I thought it might be the Rubinius one
19:06		swarley	No, Rubinius uses LLVM
19:06		swarley	Which, in my opinion
19:06		swarley	Is not the best choice for a dynamic language
19:06		swarley	But I'm not an expert, so what do I know
19:06		arnsholt	Oh, right
19:07		* not_gerd	fixed typo in pull request
19:07		swarley	Maybe it would be better to try to make a PASM -> YARV first
19:07		swarley	then maybe try PIR -> YARV
19:07		swarley	etc etc
19:08		perigrin	I think that following teh same path jnthn took to the JVM would be a reasonable choice
19:08		swarley	Well, my biggest concern is that I've not attempted something like that before.
19:08		swarley	I'm okay with lexical analysis. My biggest issue is with larger grammar construction

19:10		swarley	Do a little work with PASM
19:10		not_gerd	swarley: PASM is deprecated
19:10		perigrin	that's fair :)
19:10		swarley	It's just for learning purposes
19:11		not_gerd	and Rakudo really wants to be ported at the NQP layer
19:11		swarley	I'm not planning to use a PASM parser
19:11		swarley	I just want to learn YARV bytecode with it
19:18		jnthn	arnsholt: (REPR compose once) Yes, I tried to put in code to make sure of that in the various Perl 6 meta-objects
19:19		jnthn	Porting NQP doesn't need writing a parser.
19:20		jnthn	It does need writing a regex compiler... ;)

19:43		jnthn	https://github.com/perl6/nqp/c[…]8f1e6bbc9e#L0R111 # is that missing a cast on the RHS maybe?
19:45		arnsholt	Yeah, I'm very happy with copy_to. It keeps all the pointer-mucking in get and set
19:46		arnsholt	Right about the first one. That can be factored out of the if
19:47		arnsholt	On the second one, yeah I guess I should explicitly cast
19:47		arnsholt	You'll find the same thing in P6int, in that case

19:51		swarley	Where is the lexer/parser in parrot?
19:52		diakopter	which one... there are many
19:52		swarley	The one for PIR/PASM
19:52			MikeFair_ joined #perl6
19:53		jnthn	arnsholt: In CArray, for the sensible "0 value" it may be more Perl 6-y for the num one to be NaN.
19:54		swarley	i can't seem to find anything with a relevant filename
19:54		arnsholt	Troo, troo. So 0.0/0.0, I guess?
19:55		jnthn	*nod*
19:57		jnthn	arnsholt: Other than those small things, I'm very happy with this. :)
19:57		jnthn	arnsholt++
19:57		arnsholt	Speaking of, is there a special reason you do "float x = 0.0; value = x/0.0"?
19:58		jnthn	arnsholt: Yes, my C compiler rejected explicit 0.0/0.0 as divide by zero error...as a compile time error
20:00		arnsholt	Right, right. Keeping the compiler happy is plenty reason =)
20:03			bruges_ joined #perl6
20:03		swarley	Is there not a grammar in th parrot source tree?
20:03		benabik	swarley: The compiler for PIR/PASM is called IMCC.  It's found in parrot/compilers/imcc/
20:03		swarley	I can't see one..
20:03		swarley	Oh, alright. Thank you very much
20:04		swarley	I saw that, and I was looking for it
20:04		swarley	I just didn't know it was there
20:04		* swarley	shivers
20:05		swarley	C parsers..
20:05		swarley	oh wait, is that a .y i see?
20:05		japhb	arnsholt, this commit looks strange to me: https://github.com/perl6/nqp/commit/6b1e294f6d
20:05		japhb	arnsholt, so if bits % 8 is 2, then you're going to add 2 to bits?  Why?
20:06		benabik	swarley: Yes.  You probably want imcc.y and imcc.l
20:06		swarley	oh thank heavens
20:06		arnsholt	japhb: Der, derp, derp. Thanks =)
20:07		arnsholt	I did the very same thing for my first attempt at implementing alignment
20:07		japhb	heh.
20:07		japhb	Easy mistake to make!
20:07		arnsholt	It should be 8-bits%8, of course
20:07		jnthn	d'oh, I missed that one too

20:12			pmurias joined #perl6
20:13		arnsholt	jnthn: For the explicit casts in P6int/P6num, I'll be explicit and cast all of 'em
20:13		arnsholt	For the floats, I think FLOATVAL is going to be Parrot_Float8 on most platforms, but INTVAL is Parrot_Int4 or 32-bit, and Parrot_Int8 on 64-bit, so there I'll have to cover all the cases anyways
20:13		pmurias	swarley: porting QAST would be easier/more usefull than porting PIR
20:14		swarley	I suppose you're right. Is the parser for that in NQP's repo?
20:15		japhb	arnsholt, There are platforms where 4-byte float is necessary, but I don't know if current Parrot supports building for them.
20:16		jnthn	swarley: There is no parser. See the t/qast/ tests in the nqp-jvm repo. If I was to start porting NQP anywhere today, I'd start out getting those to pass.
20:16		arnsholt	If those platforms don't provide an 8 byte float type, NQP isn't going to compile, but if they do it's probably a good idea
20:16		cognominal	nr:  $_='a'; s :g /a/b; say $_
20:16		japhb	(And then there's the whole mess of 10-, 12-, and 16-byte floating point numbers.  And don't even get me started on 1- and 2-byte ones, because those would never get used as the standard native on anything but an old video card ...)

20:19		swarley	oh, haha.
20:19		japhb	jnthn, that is fast becoming a top FAQ, I think.  Certainly in the top 5 this last week alone ...
20:20		not_gerd	in principle, parrot should build with FLOATVAL set to float instead of the default double, but I don't know if that has ever been tested
20:20		jnthn	japhb: I'm not particularly sure where to put the answer though ;)
20:20		not_gerd	using something alse is problematic because the range of floating point types can't be determined programatically and Parrot lacks the configure logic to handle user-supplied floating-point specification
20:20		jnthn	japhb: I did say so in my blog :)
20:21		jnthn	But I guess only so many read that ;)
20:21		swarley	jnthn, is nqp-jvm a branch of github:perl6/nqp?
20:22		jnthn	swarley: No, separate repo for now
20:23		jnthn	https://github.com/jnthn/nqp-jvm-prep
20:24		swarley	oh, alright. Thank you
20:25		swarley	So, there is technically no grammar?
20:26		pmurias	yes
20:26		pmurias	Perl 6 and NQP (a Perl 6 dialect) are compiled to QAST
20:26		swarley	Okay, so is there like.. A QAST opcode listing?
20:27		pmurias	https://github.com/perl6/nqp/b[…]ocs/qast.markdown
20:28		pmurias	swarley: that's partial documentation
20:29		pmurias	swarley: https://github.com/jnthn/nqp-j[…]ree/master/t/qast
20:29		pmurias	swarley: test for QAST
20:29		pmurias	* tests
20:30		swarley	Alright.. This seems like it's going to be a long time!
20:30		swarley	and these things
20:30		swarley	QAST::Var.new( :name('knowhow'), :scope('local'), :decl('var') ),
20:30		swarley	Just named parameters right?
20:30		jnthn	var is a variable
20:30		swarley	Well ye
20:30		swarley	s
20:30		swarley	But I mean
20:30		jnthn	:decl('param') adds a parameter
20:31		swarley	:name, :scope
20:31		jnthn	Oh, I see
20:31		jnthn	Yeah, that is saying "this is a declaration of a local variable called knowhow"
20:31		swarley	alright cool.
20:31		swarley	Do these tests explain well enough what the intended operation is?
20:32		FROGGS	swarley: named params can be like: :name('value'), :name<value>, and even :$name
20:32		swarley	Also, is there a test that I should start with trying to pass?
20:34		jnthn	swarley: qast_literal.t is probably the simplest one.
20:40		swarley	alright sounds good

21:26		not_gerd	^rule
