tony-o if the sub isn't 'our'ed then it's not as available

quietfanatic Is there any way to procedurally generate routine signatures to pass to NativeCall? 00:34
I don't want to have to EVAL.
00:36 espadrine left, lembark joined
tony-o quietfanatic: i'm guessing you'd have to write something to look at the stubs in .h or the functions in the .c .. 00:39
00:40 lembark left
tony-o still, a stub that looks like int '(*ss_callback)(int, char*);' would be difficult to handle 00:40
quietfanatic I'm doing that. What I mean is
how to give NativeCall the information
I have a structure representing the function I've parsed out of the .h, I just need to convert that into something NativeCall understands. 00:41
re: class scoping, I get it now, I was just thinking with C++ brain. 00:42
00:43 jack_rabbit left
tony-o ah, your question is more along the lines of making that sub available in scope of whatever dynamically 00:43
quietfanatic right 00:46
It may be possible to create subroutines with, say, Routine.new(signature => ...) or something like that. I'll look into it.
ugexe m: class A { has $.foo = sub foo { say 1 }; }; class B is A { method bar { $.foo.() } }; B.new.bar 00:49

dduncan TimToady - thank you for your response of "the intention is that auth dominate version, such that each auth gets its own independent versioning scheme, and if two different auths match up their versions, it's by agreement or by accident, but not enforced" 01:31
yoleaux 12 Jun 2015 13:31Z <TimToady> dduncan: the intention is that auth dominate version, such that each auth gets its own independent versioning scheme, and if two different auths match up their versions, it's by agreement or by accident, but not enforced
dduncan ... so that's how it works, anyway ...
However, this didn't answer my question. 01:32
01:32 erdic joined
dduncan My question assumes what you said, that the versioning schemes of different auth don't in general line up... 01:33
The scenario I am asking about concerns when two different auth at different times whether by intention or coincidence happen to be compatible in all the ways that affect some user... 01:34
01:35 bin_005_i left
dduncan The question is how does the user request, if auth is X, I know I'm compatible with versions 5-7, or if auth is Y, I know I'm compatible with versions 42-45. 01:35
and by 'or' I mean 'and'
I assume that sometimes branches will strive to be mutually compatible in some ways even if they differ in other ways, and the common ground may be what the user wants. 01:36
Or do you think this scenario would be so rare that users should just pick one auth? 01:37
in their 'use'
Note, here I thought yoleaux would message me when I simply joined the channel, rather than after the first post, but there you go. 01:38
geekosaur lots of people idle on IRC and their clients may disconnect and reconnect randomly; be bad to lose a message bvecause that happened and then it scrolled away 01:43
(or netsplits, etc.)
dduncan Right, that makes sense. 01:44
I knew about the response because I saw it on the web archive, then came here to reply as my first thing. Guess I could have said 'ping' or something to trigger the bot and provide context for my response that way. 01:45

dduncan ugexe, thank you, I thought something like emulates might be the answer, I'll have a look. 05:02
05:06 bjz left 05:14 molaf joined
dduncan So this seems to be going at it from a different angle; rather than the consumer module enumerating the options they know they work with, they just list one, and its up to alternate suppliers to say they can step in for what was asked for. 05:15
skids Has anyone figured out a way to run a bit of "undo" code or roll back state when a rule is backtracked over? Seems tough, given the current state of Cursor. 05:17

lizmat plancast.com/p/tkm/first-contact-pa...-star-trek # seems we missed last year's party 05:20
skids lizmat: Was part of why I was asking about :let above, but things like that and dynamics can handle it for descent, but not concatinations. e.g. rx/a <rule> b || <rule> <rule> c/. 05:22

ugexe dduncan: there is always interfaces, dependency injection, and monkey typing 05:28
you can already do try require Dog1; try require Dog2; my $dog = ::("Dog1") ~~ Failure ?? ::("Dog2").new !! ::("Dog1").new I'm not sure how you add the auth/version requirements to those, but assuming they have the same interface you can use $dog as whichever one gets loaded 05:30

[Sno]: what's a homepilot platform?
[Sno] FROGGS: that's an embbedded environment (linux) built by a cross-compiling platform (open-embedded) with local adoptions
my next steps are: migrate our current environment (daisy based, > 1yr old) to fido (recent Yocto/poky/open-embedded release), update kernel and device drivers to a supported version, build jvm8, build moarvm, build nqp for jvm & moarvm 06:30

RabidGravy what do I have to do get "$some_object ~~ $some_enum_value" to work properly? It seems to always ignore the sub infix:<~~> and want a Numeric method on the LHS 13:41

FROGGS RabidGravy: an enum is a numeric thing... so only a numeric thing can possibly match 13:43
13:44 Ven_ joined
RabidGravy but can't you make it go with a more specific overload of '~~'? I have a case where I want it to possibly smart match a number of different enums in different attributes of the object 13:45

RabidGravy i.e. $obj ~~ Sometype $obj ~~ Somesubtype etc 13:46

RabidGravy that's not quite what I mean 13:50

RabidGravy I've got for instance "multi sub infix:<~~> (Audio::Sndfile:D $as, Audio::Sndfile::Info::Format $type) { $as.info.type == $type }" - it appears to ignore that 13:53
FROGGS RabidGravy: ohh, you probably want to implement an ACCEPTS method on Audio::Sndfile::Info::Format instead 13:54
RabidGravy can you do that on an enum?

RabidGravy is there a way of populating a new (potentially large) CArray from a regular Array without copying the contents element by element? 17:13
17:13 zengargoyle joined
ugexe wondering the same thing myself 17:16
skids If you were asking about making a Buf, the answer would be "no" because reasons: gist.github.com/skids/aabd2aad3d0b5ad8481b 17:17
I do not know what the formally specced disposition of CArray is for memory contiguity.
ugexe on that same note, is there a more efficient way to slice up a Buf into a single Buf made up of subbufs of the original Buf? creating a new Buf for each subbuf and then creating a new Buf for each of those seems like im doing something wrong 17:18
skids I think the general idea there was that you would use subbuf and that would just be a window into the original memory, but as to implementation efficiency there... 17:20
ab5tract skids: "not guaranteed on all implementations" <-- do you mean it is not supported by all Rakudo backends?
skids ab5tract: looking I wrote that long ago.
ab5tract the next paragraph clears up the intent of the example, though 17:21
skids ab5tract: I think I was meaning, "not bolted to the floor in the spec" 17:23
ab5tract skids: gotcha 17:26
A very interesting read
17:27 ab6tract left
skids Theoretically if you made a bunch of subbufs from a buf, and then threw away all refs to the buf itself, GC could be made smart enough to realloc to only hold the memory actually pointed to by the subbufs that you still have held, but as to whether we ever get there... 17:27
So if we are talkig about long-lived subbufs, copying might be better. 17:28
Also last time I looked at subbuf handlig code it was of the "first make it work" variety. 17:29
ugexe skids++ good stuff to know 17:32
17:35 yqt left, khisanth_ left 17:36 khisanth_ joined
RabidGravy okay, looks like it'll have to be "use NativeCall; my @foos = (^10000); my $foo = CArray[int32].new; $foo[$_] = @foos[$_] for ^@foos.elems;" 17:39
we'll have to wait for nice things 17:40
skids :-) 17:41
CArray seems to exist primarily for the "I can't carry a .elems alongside this ref" purpose so maybe the "nice thing" would be .subbuf($elems) and a is-rw-shaped-native-array coercer method on that class. 17:45

FROGGS one problem is though that you cannot tag an old release that it stops working with compiler version X 19:34

m: my num32 $a; $a = 42e8; $a.say;
camelia rakudo-moar 9c8cb6: OUTPUT«2␤»
skids m: my num32 $a; $a = 42e9; $a.say;
camelia rakudo-moar 9c8cb6: OUTPUT«131072␤»
skids So... endian/offset?
dagurval: have at it with roast. We obviously need more basic tests :-) also reference the above RT#. 21:50
21:54 Obbi_ joined
dagurval ok :-). I almost feel bad though about changing the plan in native.t, it's currently "plan 42;" 21:55
m: my num $a; say $a; # <- NaN is correct, right?
camelia rakudo-moar 9c8cb6: OUTPUT«NaN␤»
skids I don't actually know. 21:56
It kinda makes sense in an OO way and not in a C way. 21:57
But if it is supposed to be 0e0, then num32 is working for the wrong reasons.
S02: "native floating-point types default to NaN, while integer types (including bit) default to 0." 21:59
So the premise of 124084 is off, but it does highlight the bug with num32. 22:00

hoelzro timotimo: if you have time, could you have a look at rt.perl.org/Ticket/Display.html?id=125403 ? 22:02
it's causing a panda install issue, and you're the one who made the commit 22:03
skids Yeah that's been hosing up a few things. 22:04

RabidGravy Okay I take back what I said above about r/w CArray parameters not working 22:12
though I may add it to the tests, it actually does work
22:17 kaare__ left
RabidGravy so it seems there is something wrong with my code but buggered if I can see where 22:19
dalek ast: 966e2b4 | (Dagur Valberg Johannsson)++ | S02-types/native.t:
added native num tests RT 124084
skids dagurval++ 22:21
timotimo hoelzro: i have no idea what could be causing it 22:25
maybe it should be bisected?
skids timotimo: maybe line 1574? 22:26
timotimo oh! 22:27
you have already bisected it? 22:28
skids No I was just doing some light reading
timotimo huh, so try_reuse was bad?
that could explain things
remove the "try_reuse" and try again?
it's just an optimization
skids I'm working on the assumption that the RT correctly identified that.
timotimo *sigh* i broke things by not being smart enough ... again 22:29
skids Or, maybe that code that removes duplicate spesh slots just needs adjusting.
timotimo in a different context, i'd probably get fired
i was certain it'd be safe in that spot :( 22:30
skids In those contexts they should have lots of people maintaining staging environments :-)
22:39 khisanth_ is now known as Khisanth 22:40 vendethiel left
timotimo right :S 22:47
is anybody trying to build without that "try_reuse"?
hoelzro: are you trying?
i'm quite distracted here 22:48
22:49 lolisa left
hoelzro timotimo: yes, it works without try_reuse 22:50
timotimo could you please go ahead and push that commit?
hoelzro is juggling Perl 6 and houseguests
timotimo i bow my head in shame
hoelzro sure
hoelzro builds new rakudo 22:51
22:57 mr_ron left
hoelzro I'm off for the evening. later #perl6 22:58
skids o/

skids Actually, pulling that particular try_reuse did not fix panda install Sum for me, assuming rakudobrew used my local changes. 23:00
Which is hard to tell for me.
23:00 Ven joined 23:02 Ven left 23:04 diana_olhovik_ left
timotimo hm, using local changes? 23:13
i don't think so
skids Is what is left unpacked in git_reference what is actually built?
timotimo git_reference sounds like it's just for making local clones without hitting the 'net 23:14
23:14 vendethiel joined
ugexe Sum problems look like its precomp order related. if you try to precompile once, it fails once it hits tiger. try to precompile to the same directory (with the modules that did precompile still there) again and it will succeed 23:15
timotimo if you commit and use "rakudobrew triple" with the commit id it you get, you'll get your local changes definitely (if they are available in the place rakudobrew looks for it)
ugexe looks like Sum::MDPad is not in the right order after a topological sort 23:25
might just have to add a hint in there that can be parsed out by panda
skids Is that an order-preserving sort, I could just adjust the META.info 23:27
23:28 El_Che_ joined 23:29 b2gills1 joined, shamu_ joined, Sqirrel left, El_Che left, b2gills left, shamu left
ugexe it iterates through your provides and parses the source with a primitive regex that can easily miss things (as well as any dynamic stuff like require ::($var)) 23:29
23:30 Sqirrel joined
ugexe so that may or may not work 23:31
skids worth a try I guess. 23:32
ugexe with all your elaborate POD it might be the strip-pod messing with it before it parses the source 23:33
skids Yeah. 23:34
ugexe maybe try putting all your `use` statements at the very top
skids Is strip-pod smart enough to preserve .WHYs? 23:38
ugexe im unsure... you can see its probably not meant to be a perm solution: github.com/tadzik/panda/blob/163ed...der.pm#L12 23:39
23:39 BenGoldberg joined
ugexe since $=pod can output all the pod, couldnt something output everything *but* the pod? 23:41
23:42 RabidGravy left
skids Well, my test files test the pod synopsis; I wonder why that has even been working. 23:45
ugexe because panda doesnt parse out the code to run for your test 23:46
panda is just parsing source code for 'use/require/import <something>' and then putting it into an array. it does not properly parse pod like rakudo does, so it can overlook things possibly like try {require XX} which means the order it makes is off 23:47
skids OIC the strip-pod is just to temprarily eliminate cruft while it is searching for the use/requires? 23:48
ugexe yes, so if you had 'use Example' in your synopsis it wouldnt think it was part of the dependency chain count
skids got it.
skids food run. Too hungry to deal. 23:50
