lizmat so what is the status on Proc::Async wrt ".start" and ".finish" ? 00:01
japhb kbenson just submitted the perl6-course deck to HN. Anyone with an account there that would like to upvote, I guess now is the time. :-) 00:04

japhb Looks like there's a post on www.reddit.com/r/perl6 00:07
*also
japhb Apologies for the rah-rah, but this really feels like one to advertise 00:07
colomon upvoted 00:08
and now I’ll actually look at it. ;)

lizmat sleep& 00:47
tony-o is there a mechanism for react whenever process is idle? 00:48
japhb tony-o: What is your definition of idle? 01:00
pink_mist is now imagining whenever ... { } whenever ... { } else { #we're idle } :P 01:10
ShimmerFairy [Coke]: for the record, my change on that was just to match existing behavior. I'd prefer if you could do +"-:16<-42>" and it came out to 0x42 (double negation) :) 02:59

masak_venue good morning, #perl6 06:20
T minus 10 minutes for nine++'s talk
masak_venue 'If you go look at the Perl 6 FAQ, there's a section, "Why should I learn Perl 6?". It lists a grab-bag of language features, rather than a set of problems that Perl 6's new design can solve.' 06:22
from news.ycombinator.com/item?id=10168170
just wanted to flag that one up. seems we can do better on that FAQ answer.
the whole HN thread is rather on topic and interesting, in my opinion. 06:23
even though, as one might expect, a fair bit of it is "why Perl 6?"
masak_venue pink_mist: I think `whenever {} else {}` would be a non-good idea from a perf perspective 06:27
RabidGravy I think the headline could be "less boilerplate" 06:28
masak_venue pink_mist: also, using `else` for something other than `if` -- or using it for loops at all -- feels a little too much like Python's questionable for/else 06:32
ShimmerFairy masak_venue: well, 'if' or 'when' :) 06:33
masak_venue ShimmerFairy: right, but even `when` is just a funny kind of `if`
ShimmerFairy I meant to say 'with', oops
but still yes to what you said :) 06:34
vendethiel masak_venue: I think for/else is a good idea, but I dislike python's version (I prefer one where else is invoked if no iterations were made) 06:35
masak_venue vendethiel: heh.
vendethiel: I think at this point I'm of the (strange) opinion that Python's design choice is surprising/unintuitive but "right" 06:36
"it didn't issue a `break`" is strictly more powerful than "it didn't iterate" 06:37
also, the use case for it is "else (if we didn't find anything)", and "find anything" is usually associated with issuing a `break`
ShimmerFairy are there any cases where wrapping the loop in a conditional is really that much worse?
masak_venue yes-ish 06:38
I mean, there are worse code smells out there, but you're teetering on breaking DRY when you do `if @things { for @things { ... } } else {}` 06:39
ShimmerFairy masak_venue: I can see why a break would be more powerful to do an else on, but there are phasers to be put in a loop, IIRC :) . An else-ish thing after a loop would be more useful for a loop not running at all 06:40
lizmat perhaps a NONE phaser ? 06:40
FROGGS morning
lizmat to be fired whenever we didn't do *any* iterations in a loop ?
ShimmerFairy mornin' FROGGS o/ 06:41
lizmat FROGGS o/
masak_venue m: for [1, 2, 3], [] -> @things { unless (for @things { .say }) { say "no iterations" } } 06:42
GLRelia rakudo-moar 62e17b: OUTPUT«1␤2␤3␤no iterations␤»
camelia rakudo-moar e6f360: OUTPUT«1␤2␤3␤no iterations␤»
masak_venue I'm not sure how to do the "no break" thing idiomatically in Perl 6.
FROGGS lizmat: either that or allowing 'else' after loops :o)
masak_venue FROGGS: see backlog. 06:43
ShimmerFairy Interesting idea on the phaser, but that might be problematic, depending on what kind of performance gain we get from skipping looking in a loop's block
FROGGS masak: I did
masak_venue one problem would be that the NONE phaser would run inside a scope that wasn't entered.
lizmat relatedly, I think we might need the opposite of a "once" block
masak_venue (which is allowed, but a little uncomfortable)
lizmat a block that will execute always *except* the first time 06:44
ShimmerFairy I could also see something like 'if for @stuff { ... } else { ... }'
masak_venue lizmat: maybe we should call it a "nonce" block :P
lizmat masak_venue: the thought has crossed my mind :-)
masak_venue or call it "NEVAR" or something
"NOWAI" 06:45
ShimmerFairy while $condition { ... } meanwhile { ... } :P 06:46
masak_venue ShimmerFairy: the VM is not "looking in a loop's block" in any relevant sense. it's just running code it was told to run.
ShimmerFairy yeah, I figured my performance concern probably isn't much of one in any case :) 06:47
masak_venue if that's a real worry, then you need a lower-level language
but it probably isn't
ShimmerFairy masak_venue: based on my understanding, it might mean an extra subscripting call on QAST blocks in places to get to the proposed new phaser. the horror :P . 06:48
vendethiel masak_venue: seems like iffor / nonce kind a thing would be an easy macro to add anyway..:) 06:51
.oO( did he just say "easy"? )
masak_venue vendethiel: yes, I think so
modulo the usual "how to extend the language from a macro" open questions 06:52
ShimmerFairy masak_venue: to me, the first design problem that Perl 6 is there for is text processing, esp. text with non-trivial syntaxes (since grammars are soooooooooo awesome) 06:53
masak_venue I've been talking about it with TimToady++ a little during YAPC::Europe 06:54
he has some ideas that might help 06:55
ShimmerFairy I'd be interested in hearing what he thinks P6 is best for solving :) 06:56
FROGGS m: say $*KERNEL.name # lizmat: that's darwin for you, right?
GLRelia rakudo-moar 62e17b: OUTPUT«linux␤»

lizmat $ 6 'say $*KERNEL.name' 06:57
darwin
FROGGS: indeed :-)
FROGGS thanks :o)
RabidGravy it should be as there is a bit of code in Process.pm tjat depends on that
ShimmerFairy lizmat: by the way, that sorting thing I had trouble with on val()? Turns out, adding a simple check to see if there are any digits in the string brought 0.^methods.sort down from 90s to 25s :P (further improvements I've done have brought it down to the tens of seconds, still twice as long as before val) 07:02
I could push the branch if you're ever interested in testing its startup time now. 07:03
lizmat I won't have any time today... tomorrow would be better for me 07:04
ShimmerFairy lizmat: ok. You don't have to, I'm just offering in case you're interested in doing further comparisons :)
lizmat I am :-) just not today :-)
ShimmerFairy I'm also considering making a compile-time version of val() inside World.nqp or such, to handle strings with C<compile_time_value>s and perhaps free up some execution time :) 07:05
lizmat (/me is doing jnthn's talks this afternoon) 07:05
*talk 07:06
ShimmerFairy cool :)
ShimmerFairy BTW, am I right in remembering that P6 _used_ to be the normal, direct successor to P5, until things morphed into the current sibling-like relationship between the two langs? (If so, I'd like to add that historical explanation to the FAQ) 07:14
FROGGS ShimmerFairy: that was the original idea, aye 07:15
RabidGravy yeah, but it's likely that went out the window after 5.8.0 came out :) 07:16
ShimmerFairy Yeah, my understanding is "P6 started when P5 was in a slump, more work went into P5 after a while, now they're parallel-y organized, instead of serially" :)
FROGGS I can just guess but that is also what I am thinking 07:17
lizmat I have an opinion about this ;-)
FROGGS *g*
ShimmerFairy It's tempting for me to think "gee, people should've just contributed to P6 instead of giving up and going back to 5", but I assume rakudo wasn't so clearly the main impl to work on (or even existed) back then :) 07:18
Heather hi, Pugs is still being in development?
moritz Heather: no
(unless you do it :-)
vendethiel Heather: hey :). no, sadly
ShimmerFairy Not really, though I did see a commit recently that at least made it run on newer systems :)
RabidGravy I think we should re-invent the origin story like they do with superhero movies 07:19
FROGGS Heather: long time no read!
Heather FROGGS hi
lizmat
.oO( Reboot of $_ )
vendethiel Heather: do you want to make bikini run on pugs? *g* 07:20
Heather -_-' vendethiel I wish I can at least repair it 07:21
vendethiel Heather: did new idris break it?
Heather vendethiel yes
vendethiel aw :(
Heather vendethiel and error is as mystic as usual 07:22
vendethiel yes, that sounds idris-ish :-).
Heather vendethiel unless I will create yet another minimalistic reproduction
vendethiel well... it's not alike mystic error this time, this time it's error inside error because it has no relation with that is really going wtong 07:23
vendethiel
.oO( unification is both humanity's greatest strength, and its greatest weakness )
masak_venue hi Heather, welcome back 07:24
vendethiel I should get going, but anyway, Heather, you've contributed to Agda, Idris shouldn't be much harder :P. 07:24
Heather vendethiel agda refused my change! :) 07:25
masak hi
Heather hell... rakudo installer is still being that kind... 07:26
lizmat what kind? 07:28
Heather lizmat it just unpack into folder you can't specify, without even adding it to path 07:29
panda --version returns usage but doesn't tell version
lizmat well, I guess rakudo is still too modest wrt to global installation
ShimmerFairy moarvm also still doesn't default to /usr/local for linuxes, like any sensible compilable program :P 07:30
lizmat about a week ago, I added infix == eq eqv candidates for 2 Promises 07:30
the idea was that you would be able to say: 07:31
m: say (start { 42 }) == start 42
GLRelia rakudo-moar 62e17b: OUTPUT«True␤»
camelia rakudo-moar e6f360: OUTPUT«True␤»
lizmat in other words, the infix operator would block until both results are there, and then do the comparison
is this something that we would like to keep? 07:32
Heather pugs moved to stack :/
FROGGS it feels rather magical but I have not enough information to judge on that
ShimmerFairy lizmat: I feel like == and eq would probably want results, since they're coercive ops, but perhaps eqv is on the Promises themselves? 07:33
lizmat the example jnthn used in his talk, would basically become:
sub MAIN($file1, $file2) { 07:34
start { from-json(slurp($file1)) } eqv start from-json(slurp($file2))
?? 'Files contain identical JSON'
!! 'Files contain different JSON';
}
ShimmerFairy lizmat: in the sense of avoiding a couple declaration lines beforehand (my $json'd1 = start ...; my $json'd2 = start ...; $json'd1 eqv $json'd2), that might be nice. 07:35
lizmat: but are there cases aside from the literal 'start' keyword that it might be helpful? I imagine "real" starts could be a too verbose to inline in an expression. 07:36
moritz my $same = [eqv] map start { from-json(slurp($_)) }, $file1, $file2 07:37
lizmat Proc::Async.start/finish returns a promise
moritz erm, the start should be inside the block, of course
lizmat anyway, I think I'll leave that out the presentation for now... :-) 07:38
ShimmerFairy I don't think I mind comparsion ops being transparent for Promises, as long as working with the Promises themselves don't get too hard for however common it'd be to interact with those objects :) 07:39
Heather I can't read my own perl -_-' 07:44

yoleaux Ven: I'll pass your message to lizmat.
TimToady trying to make List into a tuple type doesn't work 12:21
(because it ends up forcing non-lazy trying to determine WHICH)
ShimmerFairy So we'd need a separate Tuple type if we wanted one, then? 12:22
TimToady m: prolly 12:24

TimToady oops 12:25
dalek kudo/glr: 17411ef | TimToady++ | src/core/List.pm:
List can't be Tuple

We can't afford to have WHICH based on all the elements of List, for two reasons: it's slow, and its .elems is forcing eagerness that causes the self-reference check to bring on heat-death of the universe.		 12:31
TimToady 'sides, it breaks one of my slides... 12:33
FROGGS SDD++ 12:38
Ven notices he's started to use ?? everytime he wants to write a ternary, even in ruby... 12:46
moritz in perl 5 too
FROGGS same here :S 12:48
timotimo yeah, ?? !! seems quite a bit nicer than ? :
FROGGS but more often I use ~ to concat stuff in P5
timotimo oh my ~.~
daxim unfilled array elements: I know they stringify to the empty string and their type is Any, but what is their value?
moritz daxim: Any
timotimo daxim: their value is Any, too
moritz daxim: the type object 12:49
[Coke] m: my @a; @a[4]=3; say @a[1].WHAT; 12:53
GLRelia rakudo-moar 17411e: OUTPUT«(Any)␤»
camelia rakudo-moar e6f360: OUTPUT«(Any)␤»
daxim what's the design decision for making exists and deletes adverbs and not a method like kv? 12:57
jdv79 daxim: i have wondered that but didn't care enough to ask 12:58
they seem like outliers 12:59
timotimo because we'd have to have delete_pos and delete_key
for things that behave like Match or Capture, i.E. things that have both positional and associative functionality
daxim can you give a concrete example?
timotimo i never can :P 13:01
FROGGS if there was a method called .exists instead of the adverb, you would call .exists on Any 13:02
... on any Any in fact
so what if you store Any to a slot of an array? the slot exists then but would be the same Any as a slot that is made up for you because you asked for it 13:03
timotimo mhm
FROGGS and adverbs get passed to the method, like AT-POS for the postcircumfix []
and this method can then properly check if a slot exists or not
FROGGS daxim: so in every case you want to talk to the method that is returning something instead of talking to the return value directly, you'd probably want adverbs 13:04
daxim is that the generalised explanation for the existence of adverbs? 13:05
timotimo a little bit 13:06
FROGGS daxim: put differently: adverbs are just flags to the sub/method they get applied on, so these subs/methods can do different stuff then usual 13:07
timotimo i'm not sure it helps daxim, though? 13:10
FROGGS I don't know :o) 13:10
daxim it is still a bit vague, but that's not the fault of your explanation, but my lack of experience. I figure it will sink in later 13:11
ShimmerFairy daxim: our hashes and arrays don't have some sort of encapsulating type around values it returns, so you can't really define a method to go after the subscripting. 13:12
daxim: and when you think "I could just put a method before the subscript instead, to modify what the subscript does!", well, that's what adverbs are suited for. :)
timotimo ShimmerFairy: i don't think that's what daxim is suggesting, though. as i understand it, it's more like "why not @foo.exists(10) or %test.exists('hello')" 13:13
jdv79 imo adverbs stick out as an inconsistency or a rarity where the why is not obvious. 13:16
ShimmerFairy daxim: if what timotimo said is true, then in that case there's the argument that :exists and :delete are better for demonstrating the fact that you're basically subscripting, just something slightly different happens.
.exists(42) or .delete("foo") don't visually look like a subscript access, even though that's the main thing happening in those operations ("find this thing, but just tell me if it exists" / "find this thing, and delete it") 13:18
[Coke] now controlls @perlhex 13:20
timotimo cool
friendly take-over! >:)
[Coke] has no idea what to DO with it, mind. 13:21
timotimo we'll hopefully be able to help you with that
it's supposed to be for interesting/enlightening one-liners and snippets, right?
[Coke] Sure. :) 13:22
moritz ShimmerFairy, daxim, timotimo: $match.exists($key) wouldn't make it obvious if $match{$key}:exists or $match[$key]:exists is meant
moritz and for things like IntStr (subclass of both Int and Str), a type-based distinction is impossible 13:23
ShimmerFairy ah yes, there's that critical detail as well :)
jdv79 you might be able to just pick random p6 rosetta snippets
masak_venue I have a question about rosettacode.org/wiki/Man_or_boy_test#Perl_6
timotimo i already said that! :)
ShimmerFairy Ah look, here's one now!
moritz also, we wouldn't get autoquoting from %h<key>>exists
masak_venue how come it works as stated, but not when I change `--$k` to `$k - 1` ?
jdv79 ha
moritz timotimo: yes, but I don't know if your point came accross
timotimo neither do i :S 13:24
masak_venue when I change it to `$k - 1` it hangs. and I don't immediately see why it should even be different.
what am I missing? :)
ShimmerFairy imagines a special P6 keyboard that just has «» keys, perhaps as supershift™+,/supershift™+. 13:25
timotimo neo2 has those :P
it has something very similar to supershift™
daxim in X you can use Compose out of the box, no need to learn a whole 'nother layout like neo 13:26
timotimo of course
but neo is amazing
ShimmerFairy I use compose as well, perhaps the special keyboard is just a set-aside Compose key :) 13:26
timotimo it'd be pretty cool if other layouts got the "multiple layers" treatment neo2 has without rearranging all the basic letters 13:27
so it'd be much less of a re-learn for regular folks
ShimmerFairy (or as the config files would have it, a "Multi_key", which can almost fit into our use of the word "multi")
timotimo isn't it more like an adverb key? :P
ShimmerFairy a slang key, surely :) 13:28
daxim btw neo was designed before the author learned about duckduckgo.com/?q=ISO_LEVEL5_SHIFT that's why its levels and resp. shift keys are so quirky
timotimo "quirky" meaning "doesn't work in java applications", right 13:29
?
daxim ? 13:30
timotimo i don't think i understand what you mean :|
the first few results from that search are all "how do i get my level 5 arrow keys to work with $foo"
and yeah ... it's difficult to make that work across everything 13:33
QtCreator on windows, for example ... very frustrating

lizmat but that won't work for slices

it's basically directly using the underlying logic
pink_mist oh wait, it isn't surprising; I missed that you had a say in front of the delete
daxim good to know, "underlying" means where? 14:38
jnthn EXISTS-KEY is the low-level API a collection type actually implemented so the @foo{$x}:exists actually works 14:39
ShimmerFairy the default [] and {} implementations use methods like EXISTS-KEY or AT-POS as part of their logic, to make supporting those for your own classes easier 14:39
jnthn @foo{@keys}:exists calls .EXISTS-KEY on each key in the slice, for example 14:40

Loren_ Oh.. thks. 16:06
ugexe, thks
FROGGS the next steps probably are to check all modules and try to find issues in the implementation
ugexe glad i could answer it before you could ask :)
grondilu so any early estimate on perf improvement or is that too soon?
FROGGS and after that looking into optimizations and cleanups

masak_venue (it ignores the inner/Int return type directive)
jnthn Oh... 16:08
DIHWIDT :P
masak_venue I think it should fail by forbidding doubly declaring it like that
jnthn Yeah, there's precedent for trying to catch such thinkos

jnthn rejects RT #125963 with a little explanation of why 16:47
That's one RT down :)
perl6_newbee Can someone explain how I can return two arrays from a sub? return (@array, @array1) does not work as expected. I know I could use sub irgendwas(@array is rw, @array1 is rw) but i want it the Perl way :-)
RabidGravy m: say ("a".."z","A".."Z").pick(15).join(""); 16:48

(I guess camelia ain't updated...)
RabidGravy yep, cheers
another one down ;-) only another 14 modules
jnthn heh, I should check my modules too 16:50
moritz perl6_newbee: I'm fairly certain that return (@a1, @a2) works; it's just a matter of what you do with it on the caller side
jnthn But I should probably cook us some dinner here first :)
And then probably relax, so I can more properly recover... :)
& 16:51
JimmyZ perl6_newbee: you can't do my(@c, @d) = (@a1, @a2)
moritz but my ($c, $d) = thesub() works 16:52
perl6_newbee hmm, I have my (@array, @array1) = irgendwas() in my script. But I get always all stuff in the first array. 16:53
Loren_ m: sub test() { my @a1 = (1, 3); my @a2 = (2, 4); return (\@a1, \@a2); }; my @x = test(); say @x[0].perl; say @x[1].perl; 16:54

different, still not good, I think
perl6_newbee that looks like my problem
what is 'dd'?

JimmyZ $a = $(1, 2, 3)

muraiki yay glr merge jnthn++ nine++ everyone ++ 18:14
nine Btw. Inline::Perl5 passes its own tests and the spec tests. I'm not sure if it needs further changes. Right now you often have to itemize a hash to avoid flattening which makes using Perl 5 modules from Perl 6 a bit weirder than I'd like.
Many Perl 5 APIs require you to pass a hash with arguments to emulate named arguments. Right now you have to write foo(${bar => 1}) in such cases 18:17
muraiki nine: yeah, almost all of our internal code uses named args
well, we use the: foo(bar => baz) form 18:18
and there are some weird cases where we foo({bar => baz})
but that was abandoned at some point in the last 15 years
I guess the latter form isn't uncommon in javascript ;) 18:19
nine The latter form has the advantage that you get the "odd number of elements" warning in the caller's place. 18:20
That's why it's recommended at least by some.

timotimo draw a time growth curve? :) 20:08

it's also written in C and such
Ulti fine I'll write a parallel one of a similar form
timotimo thank you :3 20:10
Ulti throw in a few native types for good measure... 20:14

so there's more or less enough of them to be interesting
Ulti doh segfault gunna have to think harder 20:24
screw it im gunna do the one that doesn't require any state 20:26
that would also be more impressive if it beats one of the non parallel ones that does a lot fewer comparissons 20:27

Ulti timotimo: yup or at least it did before 20:49
timotimo OK
Ulti this runs but screws up before finishing
tony-o or some way of injecting a sub to run in the main loop in order to read from $*IN so i can push it to a supply or separate thread

though I perhaps dont know enough about how race works to be sure I'm spawning a *tonne* of threads on that inner race 20:56

it always failed with one message or another

i'll just do 10 runs instead of 100 in the bench script
asan barfs at something here 21:00
we've allocated a frame from the fixed size allocator, later we've freed that from MVM_frame_dec_ref, but we explode inside interp_run 21:01

timotimo so it's still running in a frame that hasn't been inc'd often enough? 21:04
Ulti I'm afraid I'm going to be next to no help :Z 21:05
I just want to torture the implementors and eat popcorn 21:06
:P
timotimo fair enough :) 21:11
jonathan_ the "1 == all %($/).values" doesn't seem to work in t/03-cookies.t 21:12
timotimo can you golf the problem? 21:14
like, what's (%($/).values).perl look like? 21:15
oh it's you, gravy
jonathan_ it's in a regex, kinda tricky 21:16
jonathan_ basically it's "token foo { [ <f1> | <f2> | <f3> ] * % '; ' <?{ 1 == all %($/).values }> }" 21:18
i.e. all of f1 f2 f3 separated by ; in any order 21:19
dha So, do state variables function in P6 as they experimentally do in P5? 21:27
jonathan_ timotimo, it's a Seq of Match objects 21:28
RabidGravy dha, if you mean the initialisation is only done once then yes 21:30
jdv79 dha: state vars are experimental in p5 or they have changed in a way that is experimental? 21:33
dha I mean generally. There appears to be NO information in the P6 docs/specs about it, and I'd like to try to get it documented. C<supersede> also appears in variables.pod and that would be the last TODO in there. 21:34
jdv79 iirc they've been aroound for years now
dha jdv79 - you need to enable them with C<use feature>
RabidGravy jdv79, I've got H::U down to just the cookies test 21:35
pink_mist dha: I don't think there's anything experimental about state variables in perl5 21:39
lizmat_ dha: state variables work: they are internally used for e.g. once blocks 21:40
dha My mistake. They need to be specifically enabled, but they aren't experimental. 21:40
lizmat_ m: for ^3 { say once DateTime.now; sleep .5 }
dha lizmat_- Good. Now, they just need to be documented. :-)

dha Also, if I understand correctly, there's an anonymous state variable C<$> which isn't notably documented either, although I've seen it used. 21:41
lizmat m: sub a { say $++ }; a; a; a 21:42
camelia rakudo-moar e6f360: OUTPUT«0␤1␤2␤»
lizmat it's an unnamed state variable that is typically used in situations such as this ^^^
dha Yes, like that. :-)
lizmat m: sub a { say $++; say $++ }; a; a; a # just wondering 21:43
camelia rakudo-moar e6f360: OUTPUT«0␤0␤1␤1␤2␤2␤»
dha I'm looking to try to write docs for C<state>, hence my question about how similar it is to the P5 version, as that has some text I can work from. 21:43
lizmat looks like two unnamed state variables in the same scope are different 21:44
instances
pink_mist is that specced?
dha Are they, or is that an order of evaluation issue?
pink_mist - I think I can answer that. A couple of examples using state variables appear in the specs, but they are not actually described. 21:45
pink_mist well, I meant specifically the behaviour of more than one instance of $ there, not state variables in general 21:47
lizmat $++ is basically short for "state $foo++" with 'foo' being a unique string
pink_mist ah, gotcha
cool
dha Yeah, I don't think C<$> is specced anywhere. Unless it is nowhere near the phrase "state variable" 21:48
lizmat I think TimToady knows more about it 21:55
and on that note, I'm going to get some more sleep than last night& 21:56
pink_mist sleep well 21:57
RabidGravy jdv59, H::U should be working with GLR-ed rakudo now 22:12
Ven FROGGS: do you still need the test for cpp3? I can do it right now 22:17
(seems like there's no cpp3 branch on moarvm) 22:18
RabidGravy right, and that's all the dependencies sorted out as well 22:22
PAH! I FART AT THE GLR!
tadzik fart in its GLR direction? 22:31
yoleaux 2 Sep 2015 22:23Z <mohij> tadzik: github.com/patzim/rakudobrew
2 Sep 2015 22:23Z <mohij> tadzik: Supports shell local switching and dynamically determining the target version.
tadzik /o\
.tell mohij Wow, thanks man!
yoleaux tadzik: I'll pass your message to mohij.
RabidGravy tadzik, you know that regex you were asking about in HTTP::UserAgent? I took it out because I couldn't get it to work with the GLRed nom - adding instead five additional tests 22:37
skids So... there's some unfinished GLR business... the *@ vs **@ on sub forms in Any-iterable (and probably a few other places). 22:41
dalek kudo-star-daily: 64da386 | coke++ | log/ (9 files):
today (automated commit)
RabidGravy skids, on the other hand I am quite surprise it only took three and a half hours to make 19 modules work with the GLR in :) 22:43
so on the whole 22:44
skids Yes, it might end up for the better that those waited until after the merge, actually.
RabidGravy everyone++ # job well done people
skids ++everyone
dha +everyone+ 22:45
pink_mist every++one
RabidGravy now I can go and get ratted in the Mediterranean for two weeks with impunity :)
skids has to track down some rather elusive things in Sum.
dha It sounds like RabidGravy's plan is more fun. 22:46
RabidGravy :)
nighty night peeps 22:47
dha night. 22:48
pink_mist good night 22:50
skids m: buf8.new(1025).perl.say; buf8.new(202020202020202020202020202020202020202020).perl.say 22:53

timotimo you think we should have a bigint-to-buffer function? 22:54
skids Well right now I'm doing: Buf.new( 1 X+& (self.Int X+> ($columns-1...0)) ); and it will only get uglier without one. But you'd have to be able to specify size and endian stuf too, so... 22:56
skids Oh that's my buf1 func. but anyway. 22:57
timotimo mhm 23:03
skids Maybe pack() 23:06
timotimo we've had interest in that for some time anyway
ShimmerFairy Yeah, we still need to figure out some kind of binary grammar thing (that is, the binary data version of grammars) 23:25
timotimo aye
ShimmerFairy And ideally a syntax that's not as horrifically compressed as what I've seen of P5's pack() :) 23:27
timotimo digs into building a websocket implementation again ... 23:28
is there a good namespace for that module? 23:29
probably Net:: 23:30
