 00:14
tadzik how far in the nqp-rx testsuite are you, jnthn? 00:15
jnthn tadzik: In the non-regex bits, fairly far.
tadzik: Significant missing things include for loops and exception handling. 00:16
sorear jnthn: Have you noticed dalek is back?
jnthn sorear: Yes. :-)
sorear: It feels normal here again. :-)
sorear: Thanks for sorting it out.
sorear: It missed some of my commits earlier.
sorear: And then dupe-reported some others. 00:17
Hopefully that was a mid-fix glitch though.
00:17 Raynes left
jnthn sorear: What broke, ooc? 00:18
tadzik jnthn: will you be writing your own regex engine, or using the existing one? 00:19
00:19 Guest57296 joined
jnthn tadzik: The aim is to implement a PAST::Regex compiler and then bootstrap NQP's Regex grammar and actions on top of .Net. 00:20
dalek odel: 0f23784 | jnthn++ | dotnet/compiler/ROADMAP.txt:
[dotnet] ROADMAP updates.
jnthn tadzik: The overall goal being a self-hosting NQP.
Well, the overall goal being Rakudo running there, but... :-)
sorear jnthn: it was a combination of github switching to SSL and diakopter's VPS not having SSL libs 00:21
jnthn sorear: Ah, that'd do it. :)

masonkramer I'd like to overload prefix:<+> for a class, without touching + for other operand types. 00:33
tadzik g'night
masonkramer S13 leads me to believe that multi sub prefix:<+> (Bag $bag) is export { $bag.elems }
ought to work
00:34 mjk left
masonkramer but other types are not falling back to the builtin prefix:<+>, or anyway something is going awry. After that line, something like +8 doesn't work anymore 00:34
rakudo: say +8, class Bag { ... }; multi sub prefix:<+> (Bag $bag) is export { $bag.elems }; say +8; 00:35
p6eval rakudo 142d22: OUTPUT«error:imcc:syntax error, unexpected ')' (')')␤ in file 'EVAL_10' line 67808177␤===SORRY!===␤syntax error ... somewhere␤»
masonkramer say +8; class Bag { ... }; multi sub prefix:<+> (Bag $bag) is export { $bag.elems }; say +8; 00:36
rakudo: say +8; class Bag { ... }; multi sub prefix:<+> (Bag $bag) is export { $bag.elems }; say +8;
p6eval rakudo 142d22: OUTPUT«1␤1␤»
masonkramer that's interesting
on rakudo* interpreter, before the multi sub declaration, +8 is 8 00:37
*on mine
sorear masonkramer: you need to use our multi sub (rakudo bug)
however, the standard prefix:<+> just delegates the the Numeric method 00:38
jnthn Aye, that's probably it.
sorear so define that
jnthn That also. :)
sleep & 00:39
masonkramer Sorry, I have to define another multi sub prefix:<+>?
sorear No 00:40
Just define method Numeric() { YOUR CODE HERE }
In the class
masonkramer that's easy for prefix:<+> 00:41
but I also need to export multi sub infix<=> (Hash, Bag)
so this problem doesn't go away
sorear no 00:42
= isn't a multi sub 00:43
you can't add candidates
masonkramer ahh
that's why it's not in the docs for overloading
sorear in Rakudo, = delegates to the !STORE method on the left hand object 00:44
masonkramer Alright, so if I want to implement that part of Bag, I'll have to work on Hash.!STORE 00:46
Hmm, nope, looks like I just have to declare Bag is EnumMap, neato 00:54

masonkramer can I mutate a class at runtime? 04:48
sorry, let me rephrase that
sorear yes 04:49
masonkramer I have a Hash, %h. I want %h to become a subclass that I define after I've done some stuff with %h
basically, I'm trying to freeze %h so that assignments to its elements dies
something like %h is Hash but { at_key { die } } 04:50
sorear well, at_key is also used for reading elements 04:51
so that's a leetle tricky
masonkramer alright 04:52
Guess I need to go learn PIR enough to understand what at_key is doing 04:53
that's the final thing to implement on Bag 04:54
sorear rakudo: my %h = :a(1), :b(2); role ReadOnlyHash { method at_key($k) { my $r ::= callsame; $r } }; %h does ReadOnlyHash; say %h<a>; %h<a>++; 04:55

wow, masonkramer++ wrote a Bag! 13:27
13:28 dju left
tadzik what's a Bag? 13:28
masak it's like a Set, but allows multiple copies of elements.
or you could think of it as an unordered Array. 13:29
tadzik mhm
masak or a Hash that maps stuff to Int :)
general question: how to I map/grep on only the values of a hash? that is, I want to keep the keys of the hash intact, but transform or filter its values. 13:30
tadzik %hash.values.grep()? 13:32
colomon are you suggesting you might want to transform (say) "blue" => 42 to just "blue"?
(otherwise I don't understand what filtering values but leaving keys intact means) 13:33
masak ok, I'll give you a concrete example.
13:34 Psyche^ joined, Psyche^ is now known as Patterner
masonkramer oh, masak, I know what you're talking about 13:34
masak I want to go from { Jan => 0, Feb => 1, Mar => 2 } to { Jan => 1, Feb => 2, Mar => 3 }. here, the transformation is (* + 1)
masonkramer I want to do this a lot in perl5
moritz_ %months.values>>++ # maybe? 13:35
colomon at least in theory moritz_'s suggestion should work, I think.
jnthn %months>>++ # doesn't hypers operate ove the values by default in a hash? 13:36
moritz_ jnthn: they probably do

moritz_ masak: then copy first :-)
masak also, I chose a simple transformation, but I might want to do something more complicated.
jnthn Then why not %h.pairs.map({ .key => .value + 1 }).hash or so?
colomon %months.kv.map({.key => .value + 1}).hash
damnit, jnthn just slightly faster than me.

moritz_ hm

moritz_ I kinda think it's current spec
masak me too.
but I agree that it's somewhat skewed.
doesn't really fit together.
moritz_ becuase >>.method is really not a hyper operator, but a method call with some hyper-y semantics
which defaults to .list on its invocant
colomon are you sure that's spec?
tadzik I should get a civilized gravatar 13:44
colomon If I'd been able to figure it out, I'd have changed >>.method to match >>op
moritz_ let's see what TimToady has to say 13:45
colomon (of course, it's possible I was wrong to think that should be done!)
moritz_ a certain symmetry wouldn't be bad
colomon I'm not seeing anything obvious to me in the hyperop specs that separate out >>.method as behaving differently from >>op 13:47
masonkramer philosophical question about pull requests - what level of polish are you considering for rakudo right now? 13:48
E.G., I have a Bag that passes the tests, but it does not have the .WHICH property of immutable objects such that $x.WHICH eqv $y.WHICH when all keys and counts are identical

p6eval rakudo 142d22: OUTPUT«{"Jan" => 1, "Feb" => 2, "Mar" => 3}␤»
masak this is what I wanted.
moritz_ masonkramer: are bags supposed to be value types? 13:51
masak I was wondering if that was built in. seems not.
moritz_: they're listed under "Immutable types" in S02.
colomon rakudo: my %a = a => 0, b => 1; say (%a >>+>> 1).perl; say %a.perl 13:52
p6eval rakudo 142d22: OUTPUT«{"a" => 1, "b" => 2}␤{"a" => 0, "b" => 1}␤»
masonkramer moritz_: what masak said, "Objects with these types behave like values, i.e. $x === $y is true if and only if their types and contents are identical (that is, if $x.WHICH eqv $y.WHICH)."
I'm going to solve this *particular* problem before I issue a pull request, because I know about it, and how to fix it
however, as a philosophical point, when is it good enough? 13:53
when it has no known bugs?
colomon masonkramer: by that standard probably 50% of the commits in Rakudo wouldn't be made 13:54
moritz_ masonkramer: "no known bugs" is not a requirement
colomon if you're implementing new functionality and it mostly works, that's great.
if you're worried about known bugs, make sure tests for them are in the spectest
moritz_ masonkramer: it shouldn't have bugs that you expect to be heavily relied on, thus misleading the user 13:55
13:57 wamba left, wamba joined, satyavvd left
moritz_ masonkramer: most features first get implemented in a buggy, incomplete way. Then masak++ files ten bug reports about it, and it gradually improves :-) 13:58
masak word.
masonkramer: release early, release often. 13:59

jnthn arthur-_: The page you linked to showed a C example where they compiled the entire set of C source files for the binding into the example executable.
Zavolaj can't help you if there's no library to load.
Then 14:07
I'm not sure what can... :)
14:07 M_o_C left
jnthn Short of re-implementing the binding from the ground up, or working out how to make a shared library. 14:07
Latter should be possible.
I'm just surprised they didn't already provide one. :S 14:08
arthur-_ again, too complicated for me
I was ready to try if it did not involve any C-stuff
jnthn I'm afraid it's probably going to if there's no library handy already. :(
arthur-_ ok 14:09
tadzik awaits the new NCI branch so he could (maybe) get Loudmouth working
jnthn GET WHAT WORKING?
arthur-_ it says "library" on the c++ page : www.mongodb.org/pages/viewpage.acti...eId=133415
tadzik :)
then I could rewrite my xmpp client in Perl 6, which would be insanely awesome 14:10

masonkramer What method does for use on an object to obtain the iterator? 14:24
jnthn for is actually just map 14:25
masak I just got "Can't exponentiate a Duration" in real-world code. could someone explain to me why we have Durations? 14:26
masonkramer jnthn: in that case, what method does map use?
masak: time notation is hard and incredibly common. I think the success and ubiquity of the DateTime project in perl5 proves that there should be one comprehensive, standard way of notating time 14:28
masak I mean, what would we lose from getting rid of the Duration type, and just dealing with Num seconds?
I must confess that's what I thought I had until I got the error message. 14:29
and if I do .x, that's what I'll have.
my point is, I'd prefer not to have to do .x
when I look in src/core/Duration.pm, all I see is a lot of delegation methods, and some methods saying what you can't do. 14:30
that doesn't benefit me as a user in *any* way.
(as far as I can see) 14:31
14:31 bonelifer joined, nymacro joined 14:33 patspam joined
masonkramer If it's anything, it's that it usually doesn't make sense to do most numeric operations on two Durations. E.G., from a physical point of view, 5 seconds * 5 seconds usually doesn't make sense 14:35
masak I don't care. when I did it, it made perfect sense. no offense, but what you just said is so short-sighted it sounds like it came from a Python person. 14:36
I was calculating the standard deviation of a bunch of Durations. that calculation contains an exponantiation.
I know what I'm doing. Rakudo thought it knew better, it didn't.
masak throws the tantrum a bit more 14:37
masonkramer I'm not actually advocating Durations, mind you, I'm just reading the spec and trying to give it a fair shake 14:38
masak *nod*
I just hate when things that could be simple are complicated, and obstruct a simple solution.
I don't currently see what Duration buys us.
masonkramer It makes the program more self-documenting, for one thing. Having a Duration object gives me more info about that object that an equivalent Rat. 14:40
*than an 14:41
masak that is true.
I wasn't declaring Duration objects in my code, though. I was just implicitly (and unwittingly) using one.
14:42 spinclad joined
masonkramer The way you fmt a Duration might be different from the way you fmt a Rat? 14:43
masak not that I'm aware. 14:44
masonkramer But it *could* be
And/or you can conceive of another pretty printer for Durations
something configurable 14:45
something _localizable_
masak meh. 14:46
all this abstraction, and we don't even know exactly what we want it for. colour me unconvinced.
masonkramer I'm not even sure that your failure was to spec 14:47
masak I'm pretty sure it isn't.
masonkramer "Durations allow additive operations with other durations, _and allow any numeric operation with a number as the other argument_"
masak submits rakudobug 14:48

arnsholt arthur-_: You need to find a reference to the C bindings for MongoDB (there should be some) 16:08
The reason is that C++ function names are mangled, because function names need to be unique in the library (see en.wikipedia.org/wiki/Name_mangling...in_C.2B.2B for more) 16:09
arthur-_ arnsholt: so I need to work with C function names, not C++ ?
the only library I could find that compiles as a shared library is the C++ one 16:10
masonkramer I see .Stringy in S13, but nothing has it defined - perlcabal.org/syn/S13.html#Fallbacks
arthur-_ you say I need a C library that compiles as a shared library arnsholt ?
they don't seem to have that
just .h files you are supposed to use in your C code, I think 16:11

arnsholt There's a recent commit message that mentions support for shared libs, but I don't know how well it would work
They say it's alpha, so it might be a bit fiddly
arthur-_ arnsholt: they say how to make the .so file ? 16:18
arnsholt But if you got that built and installed as a shared lib, it whould be pretty straightforward
See github.com/mongodb/mongo-c-driver
The commit messages on .gitignore and SConstruct say that the changes were for adding support for shared lib, but that's all I know
arthur-_ gcc -o libmongoc.so -shared src/md5.os src/mongo.os src/bson.os src/numbers.os -L/opt/local/lib

moritz_ but wouldn't you get an "type check failed in return" if it were the return line? 17:38
and don't return pointers to local variables in subroutines, they are on stack and get re-used when the function exits 17:39
arthur-_ I get a Type check failed for assignment for this line : my OpaquePointer $options = make_mongo_connection_options('localhost', 27017);
so it does not return a OpaquePointer
but I just noticed compiling the lib gives warnings :
src/mongo.c: In function ‘make_mongo_connection_options’:
src/mongo.c:36: warning: return from incompatible pointer type
src/mongo.c:36: warning: function returns address of local variable
moritz_ right, that's what I meant 17:40
arthur-_ moritz_: so if I don't return a pointer to a local variable, how do I do in C a function that returns a pointer to a mongo_connection_options struct ?
moritz_ arthur-_: you use malloc() to allocate a new struct 17:41
arthur-_ urk !
this is getting more and more complicated
moritz_: how would you do it ? ^^ 17:42
moritz_ yes, urk!. It's C, of course it's irksome
I'd do it with malloc
arthur-_ can you help a little by showing how you would rewrite pastebin.com/K71cZGtf ?

In "my" declaration, typename UnManagedStruct must be predeclared (or marked as declarative with :: prefix) at line 14, near " $options " 18:02
moritz_ just omit the type constraint for now
arthur-_ moritz_: yes, worked !

oh no it does not connect 18:04
maybe because I pass $options to mongo_connect, and mongo_connect wants Opaque : sub mongo_connect( OpaquePointer $client, OpaquePointer $options)

tadzik masak: I got up at like 1 PM 18:53
masak :)
tadzik is it something like R* for Haskellers?
moritz_ tadzik: it's a document, not a distribution 18:54
masak tadzik: Haskell Prime has been a long time coming.
it's had issues similar to Perl 6, in that it tries to improve on something already successful. 18:55
18:55 toebu joined
moritz_ how much of it does GHC implement? 18:55
masak no idea.

masonkramer did my Bag / Set ideas letter make it to the mailing list? 20:01
diakopter I think so 20:09
arthur-_ and my Problem with NativeCall one ? 20:16
diakopter to which list was that one sent 20:20
arthur-_ perl6-users 20:22
found it ! ( at least the first part, the problem with isa_pmc() ) , well at least fixed it by removing returns OpaquePointer

arthur-_ plobsing: how do I use parrot-libjit-fb in Perl6 ? ( if I can ) 21:16
moritz_ araujo: what is 'no'? 21:17
21:23 lichtkind joined
plobsing arthur-_: all you have to do is load the library. then it takes over the NCI using the same interface. 21:25
so it should work transparently from under zavolaj 21:26
arthur-_ use NativeCall; ?
21:27 rgrau` left
plobsing you'll need to also loadlib it. probably "pir::loadlib__s('libjit_fb')" or something like that 21:27
arthur-_ I try 21:28
===SORRY!===
rtype not set
plobsing rtype?
arthur-_ plobsing: don't know .... 21:29
moritz_ arthur-_: it means that you tried to assign something which is read-only
arthur-_ moritz_: oh ok
not sure where, I just added the loadlib thing 21:30
plobsing: code is here : pastebin.com/FTXfDtWV
sorear (Out of curiousity, why aren't you using Perl 5?) 21:33
21:33 wallberg joined
arthur-_ sorear: ? 21:33
plobsing arthur-_: submitted update to code that I think should work 21:36
arthur-_ plobsing: update ? 21:37
plobsing to your pastebin 21:38
basically s/__s/__ps/
arthur-_ plobsing: I'm not sure where I can see it ... I try s/__s/__ps/ 21:39
plobsing: no bug, but same problem as without libjit-fb :
No NCI thunk available for signature 'ipttp'
araujo moritz_, false 21:40
arthur-_ ( I think I understood that libjit-fb was supposed to avoid creating that problem, but I'm not sure )
moritz_ perlgeek.de/article/discovering-met...t-protocol # any feedback? 21:41
plobsing arthur-_: that is precicely the problem libjit-fb as well as gsoc_nci are trying to address
arthur-_ plobsing: so why do I still have the problem, I do something wrong ? 21:42
plobsing I think somehow it is trying to build a thunk *before* the dynamic framebuilder is loaded 21:43
I'm setting up the required infrastructure (mongo install, r* install) to be able to test further
arthur-_ thanks a lot
21:46 masak joined
mkramer moritz_: just the title is exciting to me! Awesome topic. Reading it now 21:46
masak o/
arthur-_ ( for mongodb I try to use the C lib : github.com/mongodb/mongo-c-driver ) 21:47
moritz_ \o masak
masak: I just pasted perlgeek.de/article/discovering-met...t-protocol in the backlog, and would welcome your feedback
diakopter moritz_++ 21:48
masak ah, so that's the exciting title :)

lue happy end of daylight savings! (in the US at least) 21:49
diakopter in the US *except* Hawaii :) 21:50
(and other exceptions in the USA)
mkramer I hope you will disect the final code snippet piece by piece. Why is the method .^add_method named with a ^ in front? what is ^compose? Where can I learn more about ClassHOW? 21:51
moritz_ mkramer: thanks; I meant to explain ^, but forgot it 21:52
lue Would the [% %] I read about in the Web.pm README be the way to embed P6 in webpages like you can in PHP? 21:54
flussence s/in PHP/in Template Toolkit/ 21:55
;)
lue So it's not like how you embed PHP in .php files? 21:56
masak moritz_: nice post.
moritz_: I have no comments on content, except that I found the semicolon at the end of method greet misplaced.
moritz_ revmoes
flussence I'll admit I haven't actually *looked* at Web.pm yet, but the difference between PHP and TT is that TT has its own template code unless you explicitly ask for perl via a [%PERL%] block. 21:59
at this stage of development, Web.pm probably does the PHP thing, yeah :/ 22:00
22:00 wallberg left
flussence (or not, considering how easy it is to write a template language in p6 :) 22:01
moritz_ mkramer, masak: incorporated your feedback, thanks
mkramer: I don't actually know where to read more about ClassHOW, because we don't have a proper API spec 22:02
22:02 toebu joined
lue Because I would like to start experimenting with using P6 on the web so that I can build a site when I can host it somewhere. 22:02
mkramer Anyway, nifty post, thanks 22:03
22:05 wallberg joined, wallberg left
lue maak: I just can't get test 29..46 of compiler.t compiling, so I think its somewhat safe to say what I add doesn't break those tests 22:08
sorry, masak (stupid keyboard) 22:09
toebu a little problem :-) a program about mice: start with one female mouse ... after 10 weeks it bears 6 kids ... 3 female, 3 male ... after that it bears a new set every six weeks ... all females are fertile ... mice do not die ... how many mice do you have after x weeks ... find a cool way two program this in perl6 ... 22:10
Tene toebu: how many weeks before females are fertile, or are they fertile at birth? 22:13
moritz_ toebu: 1) find a solution 2) make it cool (while keeping it correct)
flussence looks like a straightforward algebra thing to me... 22:14
moritz_ flussence: the 10 weeks vs. 6 weeks thing makes it a bit harder than fibonacci
22:15 nexusone left
moritz_ if that wasn't teh case, female poluation would be 1, { 3 * $_ + 1 } ... * 22:15
masak masonkramer++ # p6l email
moritz_ and @male := @female.map: 2 * * - 1 22:16
masak masonkramer: I may not agree with all of your suggestions, but I agree very much with the need to explore that spec space.
moritz_ -> sleep
masak lue: did you get those tests to pass on a fresh checkout of Yapsi?
lue checkout on the whole thing? 22:17
masak yes.
because if they fail on an unmodified Yapsi, then we have a problem.
but I don't believe they do, since they work here.
22:18 Raynes left
toebu Tene: females get fertile after 4 weeks ... and have their first kids after another 6 ... hence 10 weeks for the first generation 22:19
moritz_ got the correct solution already ... (I need 11 integers for it ...) but I wonder how others would solve this 22:20
lue git stash ; git checkout [commands] # right?
22:20 Guest22875 joined
masak lue: `git stash` should give you a clean index. 22:21
and if you haven't made any local commits, that's the same as getting a clean checkout. 22:22
but... make sure you don't have old .pir files anywhere.
lue WIP on master: cce1b5a [doc/announce/2010.11] small fix
toebu after 52 weeks there are 4423 mice
lue is that what my stash should look like? 22:23
arthur-_ plobsing: any progress ?
masak lue: yes, that's the latest commit on github.
masak bumps the SIC version 22:24
lue where would these old .pir files be? 22:25
masak in lib/ or blib/
plobsing arthur-_: mongodb build giving me grief
22:25 risou joined
lue The only thing is Yapsi.pir in blib/lib 22:25
22:25 kjeldahl left
arthur-_ plobsing: oh ok, tell me if I can help 22:26
masak lue: nuke it. 22:27
dalek psi: 74884bf | masak++ | lib/Yapsi.pm:

lue initiating missile... 22:28
plobsing arthur-_: problem is likely on my end. I was trying to run multiple builds simultaneously. retrying unloaded. 22:30
lue aah! Should I proceed to nuking the entire repo? [then re-clone it of course] 22:31
masak lue: no, why? 22:32
lue: do the tests pass now?
lue no :( 22:33
22:33 kensanata joined
masak then yes, maybe nuke the repo and do a clean check-out. 22:33
22:33 Plastic_Chicken left
masak now would be the time to rescue your changes, though. 22:33
lue I just looked at t/compiler.t 22:34
...
29-46 are meant to say "will not compile", aren't they? [hand approaches forehead...]
masak lue, a test passes if it says "ok". are we agreed on this? 22:35
lue yes. [sorry for wasting time]
masak I take your reply as meaning that we are agreed, but that you learned it very recently. :) 22:36
does that mean that your patch actually passes all the test? that's good news, then.
lue I ignored the ok's by mistake, and when I saw "not"s, I immediately went into "O NOES WONT PASS!" mode 22:38
