moritz it shouldn't be a type variable when the class is already compose, no?

you wouldn't believe how messy my commits would look without it

jnthn wishes more developers actually cared for their commits looking good and made effort towards it. 09:33
bbkr hi. I'm trying to write nice wrapper for GeoIP libraries, however when I use NativeCall I always get "dyld: lazy symbol binding failed: Symbol not found: _dlLoadLibrary" message. I did typical "Configure.pl, make, make install" installation for Rakudo Star 2012.01, without superuser. 09:34
masak sorear: I think it's more like 17k tests for pack/unpack. still, a scary amount.
bbkr do I have to point linker to some parrot/nqp library responsible for native libraries loading? I'm on MacOS 10.7
09:35 pernatiy joined
jnthn bbkr: dlLoadLibrary is a function from the dyncall libary, which is linked into nqp_dyncall_ops 09:37
bbkr: This happens during the build of NQP.
bbkr jnthn: yes, it's says also that it expects that lib in nqp_dyncall_ops.bundle flat namespace, whatever that means. 09:41
moritz hm, is nqp_dyncall_ops properly installed?
bbkr how can I check that ? 09:42

The REPR for Rat sounds sane, btw. 11:55
Note that you'd not want to "is repr('Rat')" it, but instead set it up like we have Int: it's inlined into a P6opaque, so you can still mix in to it etc but get to hang the relevant pointers straight off the main object, not with a nested one. 11:56

moritz colomon: packing the bits of a double is something I wouldn't want to do, it's tricky to get right on all platform (re endianess of the integers etc.) 18:45
colomon surely we're already figuring endianess somewhere? 18:47

masak TimToady: I agree with both reasons for being wary of ».meth -- but neither reason feels very strong to me. 19:49
as for me, I'm mostly surprised it doesn't work already.
I know that the .meth form is slightly special, but the dot there *feels* like a prefix op. 19:50
which makes ».meth completely natural.
19:51 lestrrat left
TimToady well, it feels like a prefix if you intend it that way when you write it... 19:52
19:52 lestrrat joined
TimToady some people don't always know what they're intending 19:52
I'm mostly worried about the cargo culters on this one 19:53
hmm, I suppose »~~» is already a hyper topicalizer 19:55

TimToady speaking of which, I've been thinking a lot about a grand unification of Match, Bool, Nil, and Failure so that they are all in some sense derived from the same role 19:58

TimToady heh
my immediate goal is to define which types are appropriate to return from .ACCEPTS that will be treated as Bool is currently 19:59
moritz TimToady: I think that Failure in its current form (ie unthrown exceptions) shouldn't have *anything* in common with Match
it needs to have as few methods as possible to work effectively
TimToady well, maybe I can change your mind on that, if you'll let me
moritz maybe :-) 20:00
[Coke] TimToady: where in the specs is >>~~>> ?
TimToady it's just a hyper on ~~
[Coke] danke.
TimToady I probably need to work up a doc on success/failure types rather than just blather here 20:02

then it means extend whichever hs needs extending, I guess.
