[2013-03-02 13:18:01] <jnthn> grondilu: Odd. Does it happen when handling the return value? That is, does it make it into the C code?
[2013-03-02 13:18:29] <TimToady> does NativeCall have any access to the bitsizes of the actual C types of the calls its making, like off_t, size_t, or time_t?  or is it just guessing?
[2013-03-02 13:19:40] <FROGGS> TimToady: you have to specify it in perl
[2013-03-02 13:19:47] <grondilu> jnthn: I guess compilation is fine since it ran well with shorter strings.
[2013-03-02 13:19:53] <TimToady> which means it will be wrong on a different machine...
[2013-03-02 13:20:31] <FROGGS> grondilu: there is a char bufr[40]
[2013-03-02 13:20:45] <TimToady> would be nice to have at least the level of portability provided by C itself...
[2013-03-02 13:20:56] <jnthn> int means "machine's native integer", so that one is already covered
[2013-03-02 13:20:58] <FROGGS> grondilu: maybe that not enough?
[2013-03-02 13:21:13] <jnthn> Yes, having a size_t available would be good too.
[2013-03-02 13:21:17] <TimToady> well, but if we don't know what type off_t maps to, we're kinda hosed
[2013-03-02 13:21:29] <uvtc> Oooh. Would be nice if the repl could remember what I typed in previous sessions, so I could up-arrow to reach longer passages without needing to re-type them.
[2013-03-02 13:21:32]  * colomon has started using the github app to track what jnthn++ is doing on nqp-jvm when colomon is away from IRC
[2013-03-02 13:21:37] <TimToady> seems that info has to be out there somewhere
[2013-03-02 13:21:44] <TimToady> or debuggers wouldn't work
[2013-03-02 13:22:03] <grondilu> FROGGS: of course that's not enough.  What's the point of using a C library if it's not for tough jobs
[2013-03-02 13:22:09] <grondilu> ?
[2013-03-02 13:23:22] <TimToady> the basic problem is that using a C library is only half the solution; using /usr/include is the other half
[2013-03-02 13:23:40]  * grondilu really wonders where this 40 comes from. 
[2013-03-02 13:24:29] <geekosaur> you can get it from the symbol table, but only to a point: you get the size, but not e.g. signed-ness unless it has debug symbold

[2013-03-02 13:24:43] <geekosaur> and then you have to know how to parse the various kinds of debug symbols out there...
[2013-03-02 13:24:52] <nwc10> is now: time        = 181.15300011634827
[2013-03-02 13:25:00] <TimToady> well, we can get signedness from the Perl end, if we can get the size from the C end

[2013-03-02 13:29:13] <FROGGS> uvtc: this calls .gist on it which should do the job (that is the one you can improve on you own classes)

[2013-03-02 14:28:00] <colomon> "given" a match, is there a handy way to "when" on a subrule?
[2013-03-02 14:29:21] <colomon> so given something like token mode { <major> | <mixolydian> }, I'd like to say given $/<mode> { when .<major> { do something major } when .<mixolydian> { do something mixolydian } } .  That syntax seems to compile but not actually work.
[2013-03-02 14:30:45] <jnthn> Remember that when does smartmatching.
[2013-03-02 14:31:02] <colomon> jnthn: yes, I remember.
[2013-03-02 14:31:09] <jnthn> So you're doing $_ ~~ $_<major>
[2013-03-02 14:31:26] <TimToady> try :major
[2013-03-02 14:31:38] <TimToady> no wait, that's a method call
[2013-03-02 14:31:43] <jnthn> that...yeah.
[2013-03-02 14:31:54] <colomon> pity, it looked so elegant
[2013-03-02 14:32:13] <TimToady> so, why not just use an 'if' instead?
[2013-03-02 14:32:43] <colomon> TimToady: there are actually nine different modes.  above is vastly simplified
[2013-03-02 14:33:05] <TimToady> when so .<major>
[2013-03-02 14:33:21] <jnthn> ooh, that one should work...
[2013-03-02 14:33:37] <TimToady> though a Match is supposed to be like a Bool, by recent spec
[2013-03-02 14:33:40] <colomon> \o/
[2013-03-02 14:33:52] <TimToady> so when .<major> should work
[2013-03-02 14:33:58] <colomon> TimToady++
[2013-03-02 14:34:46] <TimToady> so 'when .<major>' should work
[2013-03-02 14:35:09] <TimToady> (just to be clear)
[2013-03-02 14:35:19] <colomon> understood the first time
[2013-03-02 14:39:03] <colomon> is there something wrong with this syntax?  <accidental=["#" | "b"]>?
[2013-03-02 14:39:22] <colomon> it's parsing, but it doesn't seem to be working the way I expected it to.
[2013-03-02 14:40:17]  * jnthn soulda expected $<accidental>=["#" | "b"]

[2013-03-02 15:43:26] <pmurias> it's seems to be an object with a P6opaque repr but it also seems to inherit a dummy set_str?
[2013-03-02 15:49:20] <jnthn> P6opaque knows what to do with set_str provided there is a box_target set on a native string attribute.
[2013-03-02 15:49:58] <jnthn> And yes, in that test the REPR of the type is P6opaque. The meta-object is a KnowHOW, with KnowHOWREPR. That REPR is purely for bootstrapping, though...it's useless for anything more than that.
[2013-03-02 15:50:20] <jnthn> Note that if you're looking at nqp-jvm, you won't see the set_str method in question 'cus it's generated.

[2013-03-02 16:48:30] <uvtc> Would be nice to have a dedicated p6 mode, even if only simple comments and strings were highlighted.
[2013-03-02 16:49:14] <geekosaur> I don't think perl6 syntax has undergone any radical changes recently?

[2013-03-02 16:50:01] <uvtc> So, that cperl mode is supposed to do double duty as p5 and p6?
[2013-03-02 16:52:39] <Juerd> geekosaur: Nah, I'm afraid to propose swapping infix : and => around.

[2013-03-02 16:53:22] <geekosaur> point was more that I don't think an existing perl6 editor mode would have bitrotted much
[2013-03-02 16:57:28] <uvtc> geekosaur: right. Thanks.

[2013-03-02 18:19:56] <lue> S02:744 shouldn't that be Rational[int128,uint64] ? (uint64 instead of what it says, int64)
[2013-03-02 18:24:02] <TimToady> yeah, probably
[2013-03-02 18:25:05] <lue> I'll fix it then. (I thought maybe there was a reason for the switch)
[2013-03-02 18:25:06] <TimToady> no point to storing the sign in two bits
[2013-03-02 18:25:52] <TimToady> though I'm sure the JVM would be happier with signed types, sigh
[2013-03-02 18:28:26] <lue> Mathematically, you'd have to xor the high bits (-3/-5 = 3/5, not -3/5)
