dalek rakudo: review: github.com/rakudo/rakudo/commit/e6...f51459d459 00:00
00:00 timbunce left
masak for those following along at home, this also means that we didn't have any spectests for &elems. 00:00
00:00 timbunce joined
masak someone with a spare tuit or two might want to... 00:00
00:03 risou_ left
Tene might want to... submit a spec patch that removes &elems from the spec? 00:03
masak actually, it's just an exported .elems method. 00:04
and the Druid code that failed in its absence actually showed a decent example of when it's useful.
hm. I should clarify. in the spec, it's just an exported .elems method. in Rakudo, it's a sub. :) 00:05
if anything, I'd prefer a spec patch that regularized which methods are exported and which ones are not. 00:07
rakudo: say perl [1, 2, 3]
p6eval rakudo 4d33ba: OUTPUT«Could not find sub &perl␤ in main program body at line 22:/tmp/nwPkhmhnPH␤»
masak S32 says (twice!) that it's exported.
rakudo: 42.say; 42.warn 00:08
p6eval rakudo 4d33ba: OUTPUT«42␤Method 'warn' not found for invocant of class 'Int'␤ in main program body at line 22:/tmp/e1buizM9fm␤»
masak where's the consistency in the STDOUT method being there, but not the STDERR method?
Tene I'm a bit leery of the method/sub proliferation, personally.
masak I wouldn't mind it so much if it had some kind of pattern.
Tene Yeah. 00:09
Exactly.
masak same thing, only more so, with the high/low-level means of type conversion. .Str/.Stringy/~, .Num/+, .list/.List (I don't even know which ones are the latest variants of this one)... 00:11
if these are not very, very clear and pattern-ful, they're going to be a sore point. 00:12
Tene and that last also has &list
Makes me rather nervous.
masak that's ok, because there's also &hash, and then similar ones like &eager and &hyper.
generally, I have more sympathy for when there's a sub form *and* a method form, than for when one of them is missin.g 00:13
s/\.g/g./
00:14 cls_bsd joined
masak I've been reading A12 a bit today, and it boasts about the sub call form and the method call form being syntactically different but semantically equivalent. that's no longer true, and we have to compensate for that un-equivalence with a corresponding amount of design discipline. 00:15

sorear to-radians, really? 08:40
whose bright idea was it to make handles Cool?
Grimnir_ which one should I use to get all data from a filehandle? like do { local ($/); <STDIN> } ? 08:41
sorear $*IN.slurp
moritz_ slurp
sorear moritz_: So far I've successfully avoiding acquiring a VPS. Would blogs.perl.org then be the best option?
Grimnir_ oh, nice
thx
sorear you can also just use slurp;
the function form defaults to $*IN
Grimnir_ ah, ok, thanks 08:42
moritz_ sorear: it's fine, yes. The other Perl 6 hackers seem to prefer wordpress.com, but I like blogs.perl.org
sorear ... For some reason I thought WordPress was a CMS that I had to install
moritz_ sorear: it's a blogging software, but you can also get a hosted thing for free 08:43
that's what the advent calendar used
sorear observes that moritz is using perlgeek.de
...perl6advent.wordpress.com, is that the right link? 08:44
oh
moritz_ sorear: I've built my own blogging stuff out of my offline CMS and blosxom, a very un-modern perl blogging thing :-)
sorear misparse
moritz_ and I regret some of the decisions I made for my own blogging stuff 08:45
it won't scale
mathw yes, wordpress.com is the hosted wordpress service, and wordpress.org is where you can get the software to install on your own server 08:47
I do the latter 08:48
although I very rarely actually blog these days
moritz_ didn't know that mathw had a blog
mathw Well I do 08:49
I always intended to work up to blogging a lot about Perl 6 and get it on the Planet, but then I didn't
mathw should do some more Form coding at some point
...after nanowrimo though 08:50
and write documentation, that would be good too

who is the pumpking for misc/perl6advent-2010/topic-brainstorming ?
moritz_ sorear: tadzik is. But you can add topics without his involvement
sorear heh, tadzik's name contains characters urxvt can't render with one font 09:11
So *suddenly switches to something with serifs and notably lighter* s'
moritz_ sorear: I'm not sure yet which program is to blame... will try rakudo on the command line once I've compiled it again 09:12
sorear ilbot2 isn't seeing the » 09:13
moritz_ right
sorear ilbot2 is Perl5, right?
moritz_ it is
but it's POE magic that tries to utf-8 decode the input
maybe it stops when it encounters illegal characters
sorear embedded nuls aren't illegal in utf-8 09:14
moritz_ right, just figured that out
or maybe it's a new rakudobug 09:15
sorear I suspect ircd-seven
it's a large C program
Parrot probably has its own share of NUL bugs, but Parrot is not in a position to prevent » from being emitted 09:16
since it's emitted by perl5 code in evalbot
moritz_ right
I forgot that
still worth checking what rakudo does with \c[0]
sorear also, you can remove "experimental" from p6eval's tagline anytime you want
moritz_ $ perl6 -e 'print "foo\c[0]bar"'|hexdump -C 09:17
00000000 66 6f 6f 00 62 61 72 |foo.bar|

moritz_ any suggestions what to escape it to? 09:22

sorear at some point I need to prune dups from that file 09:35
and sanely pretty-print it
sorear wonders whether a Niecza Project Blog or a sorear-blog would be better
moritz_ having a default branch of 'master' would let us remove quite some cruft 09:36
sorear: an 'everything sorear has to say about Perl 6' blog would awesome
sorear moritz_: master is the default branch; that falls under "sane pretty printing" 09:37
moritz_ then I'm going to remove some master defaults
sorear I made all the defaults explicit as a side-effect of redumping the file 09:38
moritz_ what's the default for 'channels' ?
sorear [ [ "magnet", "#parrot" ] ]
sorear has some trepidation about starting a blog... though I suppose I haven't kept very hidden on logged IRC so I shouldn't 09:39
hmm.
#parrot seems to have adopted "metacommitter" as official jargon
moritz_ for quite some time actually 09:40
sorear I made up that word sometime back in March while fumbling to explain some aspect of pugscode
moritz_ docs/project/metacommitter_guide.pod in the parrot repo exists since 2007
sorear: in dalek-conf.json one URL is quite different from the rest 09:41
github.com/chrisdolan/perl/tree/master
sorear the hq9+ one?
oh 09:42
moritz_ should I remove the tree/master ?
looks wrongisch
sorear it doesn't hurt either way
the parser ignores everything after the fifth slash
it regexes out the "chrisdolan/perl" part, then appends the branch list 09:43

masak hi, #perl6 10:51
vxz Hello masak. 10:54
10:56 wamba joined
masak lately I've been pondering whether it'd be possible to make nested classes (à la A12) mesh with current Perl 6 OO. specifically, I'm trying to determine whether the "virtual nested class" idea of A12 is too much magic or "just enough". 10:56
moritz_ kinds thinks that nested classes only make sense when they are stritly private to the outer class 10:57
10:57 p6eval left, p6eval joined, ChanServ sets mode: +v p6eval
masak well, I can certainly see them make sense in other circumstances as well. 10:57
moritz_ rakudo: say "ab\c[0]def" 10:58
p6eval rakudo e6486e: OUTPUT«ab␀def␤»
masak sometimes classes are even nested for no better reason than that it helps the disposition of the code. 11:01
a bit like we tend to put subs in methods nowadays.
those *are* "strictly private", but that's the default for subs. the default for package-like things is not to be. 11:02
moritz_ and that's where the problems come from
to make a previously private sub public, you can either (1) mark it with our or (2) export it 11:03
for (1) it's easy to see that local sub name is just a lexical alias to a fully qualified name
and (2) just installs the the lexical alias where you use it 11:04
however it's not so easy for type names, because fully qualified names and short names looks alike
class A { class B::C { ... } # you wouldn't know if B::C is fully qualified, or a lexical alias, just by looking at the name } 11:05
masak nod
moritz_ class B { 11:06
class B { }; class A { class B { }; # what's B here ? }
masak I would assume that it's the inner one.
moritz_ one possible resolution is to only ever allow fully qualified class names 11:07
but it's not a nice solution
masak was just going to say that.
moritz_ faster :-) 11:08
masak :) 11:09
tadzik o/
phenny tadzik: 09 Nov 22:15Z <masak> tell tadzik that neutro bootstrap worked fine on my box.
masak this is one area where I don't have any real-world experience. I haven't even been using nested classes that much in other OO languages. I'm not aware of any typical examples where nested classes turn out to be just right. 11:10
I'd guess it varies a lot from language to language.
\o, tadzik.
moritz_ anyway, that's why I suspect there's no good solution to inner classes that DWIW
masak right. 11:11
nom &
11:11 masak left
mathw The only thing I really use nested classes for is in C++ when I want it to have some internal type 11:12
and I often make them private
I've never run into a problem with their semantics that I recall, but I'm never really doing anything elaborate - it's really just a namespacing thing that I do 11:13

moritz_ bbkr: not sure if you are allowed to use ^add_method on instances, and without calling .^compose 12:12
12:14 ggoebel left
bbkr moritz_: but instance is blessed. so where is the problem? HOW on blessed instance should give class metaobject anyway, right? and it works the other way round: self.^add_method("foo", method {say 666} ); self.bless(*) 12:15
moritz_ bbkr: the problem is that .^add_method is an API for classes, not for instances 12:16
$obj.^foo() desguars to $obj.HOW.foo($obj)
so in one case you're calling a method from the meta class with an instance as first argument, and in the other with a type object 12:17
and the spec doesn't indicate that it's OK to pass an instance
bbkr moritz_: you're a genius. clear and simple explanation :)

bbkr ok, another question. "$instance does role { method foo{} }" works like a charm. but what if name of the method is not known in compile time but comes in variable? is there any magic syntax to express "method $name {} " ? 12:37
moritz_ you need something along the lines of 12:39
my $role = RoleHOW.new();
$role.^add_method($foo, method () { } );
$role.^compose()
$instance does $role

bbkr moritz_++ # trick works! 12:42
moritz_ actually I stole it from jnthn++ via timbunce++ :-) 12:43
masak bbkr: you asked about "a phaser that can replace now BUILD known from P5 Moose (executed at the beginning of every object creation)". there's a submethod called BUILD, and one called BUILDALL. it's more common to "override" those than to provide a new .new method in one's own classes. see S12 for more info. 12:48

12:55 kst left
tadzik this still happens to me. Gotta write more 12:56
masak come to think of it, it was the same with me and Chinese characters. they used to be this exotic, mysterious medium of writing -- seemed more like something someone made up than an actual writing system. 12:59
vxz It's...both?
masak then I learned stuff about it, and it all sort of settled into a more realistic viewpoint. still pretty cool, of course, but much more tangible.
vxz: well, lots of people contributed to making it up, of course. in a sense, it's a continuing, massively parallel computation. just like all other forms of human communication. 13:01
vxz masak: and the rest of the universe.
masak a hundred and fifty years ago, the universe was a steam engine. so, sure. the universe is a computation. :) 13:02

vxz Hmmm...steam-powered computation...
masak moritz_: sounds good to me. 13:04
vxz starts thinking about ways to power his laptop off of steam
moritz_ vxz: have fun with the cooling... :-)

flussence I have a crazy idea: generating vim syntax files from p6 grammars. The more I think about it though, the more impossible it looks... 13:16
masak it wouldn't surprise me if the latter were strictly more powerful than the former. 13:17
moritz_ even if you can write such a converter for normal grammar rules, you still need to translate the operator presedence parser 13:18
arnsholt I think masak's right 13:19
But generating them from a limited subset of Grammars might be viable
masak absolutely.
arnsholt And might make the whole process a bit simpler =)
moritz_ I think the real problem is that for syntax hilighting you need a lexer, not a parser 13:20
and if you translate a full parser, it'll be way too inefficient
arnsholt True. Also, the vim syntax is more than a bit funky, IMO =)

bbkr: did you read S12?
bbkr It says that submethod is something not inherited. But anyway - using "submethod" works, thanks! 13:59
moritz_ if it were inherited, it would be executed twice during initialization
masak A12 has a lot of wording about how methods and submethods do or don't participate in multiple dispatch, and about how multiple dispatch is an agreement of some sort between caller and callee. I don't follow it all, but it seems we've gotten rid of a lot of the complexity there. 14:06
hm. I think part of what disturbs me about the "Not Invented Here" and "Invented Here" terms, is that they denounce what they describe. that doesn't seem to be a very healthy thing for terms to do. and it messes with my reasoning about them. :/ 14:09
i.e. something that was invented here is an example of the "Not Invented Here" syndrome. 14:10

colomon boy, nothing in it jumps out at me as being an obvious source of the slowdown
masak smash: the underlines on the digits in the table create a lot of visual clutter, and are slightly confusing because those aren't links.
colomon ....unless it has something to do with switching from .munch to [^100] ? 14:44
masak you're changing the scripts!?
colomon masak: had to, it wasn't actually compatible with older Rakudo. 14:45
smash the script changed, but the benchmarks re-ran for all the releases
colomon unless something weird is going on, ... what smash said
masak smash: oh, good. smash++
colomon thing is, when I add a benchmark script like that, I try to calibrate it to be about the same timing as the others in its neighborhood, so the graphs look right. 14:48

sorear "get eval working" is my long-term goal
patrickas it would be cool if niecza would go from 0% to 50% in one day :-) 19:57

p6eval rakudo e6486e: OUTPUT«01001110»
Grimnir_ what's the difference between split and comb then?
rakudo: my $content = "30 31 30 30 31 31 31 30"; :for $content.split(" ") { :16($_).chr.print } 22:08
p6eval rakudo e6486e: OUTPUT«===SORRY!===␤Confused at line 22, near ":for $cont"␤»
masak Grimnir_: split throws away the matched things, comb keeps them.
Grimnir_ rakudo: my $content = "30 31 30 30 31 31 31 30"; for $content.split(" ") { :16($_).chr.print }
p6eval rakudo e6486e: OUTPUT«01001110»
Grimnir_ ah, of course
nice one
masak Grimnir_: the Perl 6 culture has a bit of a .comb bias. 22:10
(because we like to think positively) :)
Grimnir_ hehe :)
it's also nice
it makes great one-liners
when some of my friends start to go on a "write in base64 or binary" mode, I always find that I don't have a script for it, so I try to make it in a one-liner 22:11
it's good practice
masak Grimnir_: you reminded me of this post: strangelyconsistent.org/blog/the-ge...-in-perl-6 22:12
Grimnir_ rakudo: my $dna = "ttaagg"; sub translate($dna) { "FFLLSSSSYY!!CC!WLLLLPPPPHHQQRRRRIIIMTTTTNNKKSSRRVVVVAAAADDEEGGGG".comb[map { :4($\_) }, $dna.trans("tcag" => "0123").comb(/.../)] }; say translate($dna)

Grimnir_ hmm... can't get it to work 22:13

Grimnir_ I think I'm missing something here. what's the point with it? 22:16
masak I'll explain, but how much do you know about DNA and amino acids? 22:17
Grimnir_ not so much ;)
very little
I know the A, C, G, T stuff, but only extremely basic
masak oh, good.
that's the DNA> 22:18
now, that's just digital information; it needs to get "translated" into a physical structure.
22:18 sheepy joined
masak the physical structure is protein, made of amino acids. 22:18
22:18 sheepy left
masak there's a machine in our cells that takes DNA, three bases at a time, does a hash lookup and produces an amino acid. 22:18
it strings those together into a long chain, and folds the chain. 22:19
what the &translate sub above is doing is simulate the conversion from DNA bases to amino acids.
TimToady said TTA GGG. that translates to the amino acids L and R. 22:20
each letter there is actually a small molecule fragment of some sort.
notice how I used .comb(/.../) -- that's the part that chunks the DNA up into three bases. 22:21
it's all very evocative of how the cell itself does it :)
Grimnir_ very nice :)
masak in a way, all life on Earth indirectly contains that string, "FFLLSSSSYY!!CC!WLLLLPPPPHHQQRRRRIIIMTTTTNNKKSSRRVVVVAAAADDEEGGGG", sometimes with minor variations. 22:22
Grimnir_ is that string enough?
masak well, it's more of a lookup table.
22:23 mavrc left
masak but neither the string nor the table is actually represented in our bodies, of course. 22:23
it's just there implicitly, at least as far as I know.
Grimnir_ of course
so how did you make that string?
masak I went to the Wikipedia article and typed down the entries of the table in some order. 22:24
don't remember any more exactly how I figured it out which order was right. 22:25
probably the structure of the table makes the order obvious-ish.

I imagined something really incriminating :D
sorear diakopter: are there any tos or other issues with me installing a httpd on dalek's vps? 22:35
diakopter no
feel free; nginx, lighttpd, apache, whatevs
that new ultra perl one

22:38 gbacon left 22:41 amkrankruleuen left
sorear what do you recommend 22:41
the only httpd I've ever used is apache2 22:42
but that seems overkill for "I need to handle POST to /dalek"
diakopter heh
I'd use danga.com/perlbal/ or starman for that 22:43
flussence I prefer lighttpd over apache, haven't tried others though... 22:44
sorear looks up what PSGI is 22:46

arnsholt masak: My friend who lived in Spain at the time commented that the really scandalous part was the familiar adress 23:23
Apparently the "shut up" part wasn't that important =D 23:24
masak arnsholt: I can imagine.
arnsholt: a French teacher of mine said he came to Sweden and the first thing he saw was an advert "Have you changed your underwear today?"
arnsholt: for him too, the scandalous part was "du".
arnsholt Indeed 23:25
I still struggle with the whole T/V distinction in French 23:26
Never quite sure which is appropriate in a baffling number of contexts
masak thundergnat: seems the README itself is fine, but there's a rendering bug in github.
unless it's a feature, and I'm just a victim of it. 23:27

On another note: on the perl6.org compiler page - perl6.org/compilers/ -, the last three links in the supplementals section are giving me 403 and 404s when I try to visit them. 23:45
Have they been moved to another location? that anyone knows of? 23:46
diakopter yes, sec
thundergnat I'll even volunteer to fix them if I know the new locations.
masak thundergnat++ # noticing broken links
seems diakopter++ is on it. 23:47
diakopter for the elf ones, I don't know exactly where those are (setting & lisp) but the elf & elfish links on the left column are valid/updated.
sorear mildew/smop needs an overhaul before it's usable again 23:48
recent versions of gcc are a lot more memory hungry and want >4GB to compile the million-line intermediate files mildew spits out 23:49
thundergnat Also, it may just be me, but it took me about 30 minutes to figure out that the link for proto.perl6.org was the link to modules.perl6.org.
23:49 wamba left
masak sorear: why not just use an older version of gcc? 23:50
thundergnat It may be worth having a dedicated link to "Here's some perl6 modules contributed by the community!"
masak thundergnat: that's modules.perl6.org -- or am I misunderstanding what you just asked for? 23:51
diakopter suggesting a link
thundergnat Yes. But ther is NO link anywhere on perl6.org for modules.perl6.org
proto.perl6.org gets rewritten to modules,perl6.org. 23:52
23:52 cdarroch left
masak that link should probably be modules.perl6.org 23:52
proto.perl6.org was an old, misguided name. 23:53
thundergnat silly me I was trying to find the modules page and was just hovering over the links looking for it.
