AlexDaniel asdfgh: I wonder, why not use opengl directly? 00:07
asdfgh I've never done that before
timotimo we don't have an opengl binding, is why 00:09
00:09 tushar left
AlexDaniel ah well, somehow I assumed that this question is not perl6-specific, oops 00:09
but yeah, I'm not saying that this is the right way (or the easiest one), but it worked great for me several times (especially for game-related stuff). This was not perl 6 though 00:10
perhaps it's a great opportunity to get opengl bindings done, right? ;)
timotimo *shrug* 00:12
we have some start of an opengl binding by someone who intentionally abandoned it immediately after the PoC was done
(a colored rotating triangle)
GTG 00:14
asdfgh Is opengl any harder to use directly? 00:20

BenGoldberg I just learned of a new (to me), cool way of using reference counting for automatic memory management <hboehm.info/popl04/refcnt.pdf> ... now if only it could properly free circular reference loops as a mark-and-sweep gc can, then it would be awesome :) 00:39
00:41 girafe2 joined 00:44 girafe left
BenGoldberg The interesting thing about the scheme is that, when an object's refcnt goes to 0, it's not freed right away, but pushed onto a stack of to-be-freed objects. Whenever a new memory allocation of N bytes is about to be done, repeat the following: {one object, O, is popped from the stack. if O is a container, it's contents get their refcnts decremented, and perhaps pushed onto the stack. O is then freed.} until either at least N 00:45
bytes have been freed, or the stack is empty.
This avoids both the typical program pause which happens when a conventional gc is done, or the pause which happens in a conventional (like perl5!) refcounting scheme, in which freeing a container results in some *recursive* refcount decrementing, which can result in a program pause. 00:49

tushar my attribute definition is "has Array @.data is rw = [];". I would like to access it in a private method. I am achieving it as "@!data". Am I doing it a right way? When I attempted to access it as "self@!data", I experienced an error. 00:59
Error Message: "Invocant requires a type object of type Array[Array], but an object instance was passed. Did you forget a 'multi'?" 01:00
Any thoughts?
MasterDuke @!data is correct 01:16
docs.perl6.org/language/classtut#i...wigils_%21 has some info about the ! twigil
tushar MasterDuke, thanks. 01:17
MasterDuke, I read that doc. Any thoughts on the error that I am experiencing while using "self@!data"? 01:18
just curious..
timotimo i can't get that error
i always get "two terms in a row"

MasterDuke i agree the error is weird, but i wouldn't have expected self@!data to be valid syntax 01:21
tushar timotimo, I got the same error as MasterDuke. my class definition and method definition is also similar to what he tried. 01:22
yes, I am expecting the same. Doc shows the same syntax and I am just following it.
MasterDuke tushar: what is the exact line you're using? i can't seem to get that error with 'self@<anything>', but 'self.@<things>' sometimes does

timotimo well, our logic is "most errors are Two Terms In A Row, but sometimes we can make a better guess", so i suppose in this case it sees "you've put an 'unless' in front" and says "that's not just a TTIAR, it's a missing block!"

poohman Hello all, I have a question on Grammars, if I parse a file using the parse file function using an actionclass and assign it to a variable and print it I get the entire tree as ouput 06:15
If I assign .ast of the parsefile to it I get no output even though I have a make 06:16
It just outputs (Any) 06:17
How can I access the data member that I made??

moritz poohman: you also need to make in the TOP rule 06:29
06:29 skids left
moritz poohman: then .ast on the result should give you something 06:29
poohman ah
ok I made it in a lower token 06:30
ok thanks for the help, ill give it a shot
06:30 AlexDaniel left
poohman moritz: I already called a new in the method - how do I call the same object back in TOP - timotimo told me yesterday that it is referenced by self 06:32
Or can I make it only in the TOP rule? 06:33
moritz poohman: can you show your code please?
TimToady all make ever does is just stow a pointer to some object
moritz poohman: in many cases, you call make() in most action methods 06:34
TimToady doesn't care where you did .new
moritz and basically create a tree of result objects, that partially mirrors three of matches in the match object
TimToady { make $<something>.made } should oughta be enough
moritz poohman: github.com/moritz/json/ is an example that builds a data structure mirroring a JSON string as it's parsed 06:35

hope that works 07:00
moritz poohman: first of all, you should really add whitespace to your regexes to make them more readable 07:01
07:01 domidumont left
moritz poohman: second, you call make() in name, so only the 'name' match object has an .ast 07:01
poohman moritz: how can I access name in MAIN? 07:02
moritz so you can add a method assigns($/) { make $<name>.ast } to propagate it to the 'assign' match object
07:02 domidumont joined
poohman and then all the way to TOP? 07:02
moritz right 07:03
07:03 kssgill left
poohman I was trying with make $<name>.made 07:03
moritz and then method line($/) { make $<assigns>.ast if $<assigns> }
.made and .ast are synonyms
I think .made is more politically correct these days :-)
poohman ah ok - but is there any way I can access name directly in main? 07:04
moritz and method TOP ($/) { make $<lines>.map: *.made }
and *then* in the mainline, you can say $times.ast -> $thing { say $thing } 07:05
better: and method TOP ($/) { make $<lines>.grep(&so).map: *.made } 07:06
afk&
poohman cool thanks will try it out - coding after a decade and directly in Perl6 - awk brought me here - a big change from C++ - loving it 07:08

the default permissions on the perl6 org now contain write permissions for members 07:44
everybody in the org can create new repos in the perl6/ namespace

Woodi today HN promotes dislikeing OO :) www.yegor256.com/2016/08/15/what-is...mming.html but we still don't have replacement or recipe 11:10
tadzik hehe, pointing out flaws is always easier than coming up with alternatives :) 11:12
a lot of this criticism seems more directed either at people who misunderstand/misuse OO or particular languages 11:13
Woodi Linus T. was probably closes with recipe :) 11:14
brrt i think object oriented programming has been hugely succesful at enabling the development of large programs 11:15
the problem is of course that we are now stuck with large programs 11:16
tadzik funny thing about that C quote is it's very carefully cropped
IIRC he also says "We've been writing object oriented code in the kernel in C for years and it's perfect"
but that would not work towards the author's point, would it ;)
Woodi also Kay sayd "messages!" but we read it "messages everywhere!", but inside objects messages are harmfull, IMO 11:17
brrt tadzik: i recall that bit too
11:17 inra left
tadzik the biggest takeaway for me from Kay's idea is "object are there to ensure that the data they encapsulate is always correct" 11:18
so: managing responsibility
which is something we need to be doing one way or another 11:19
brrt true
nine I think of the listed quote the one by Oscar Nierstrasz is the most sensible.
tadzik the biggest thing to criticise in OO is imho the way it's taught
Woodi tadzik: structs are realy nice :) struct Driver { int fd; void*mem; } + some functions totally skipping VirtualDriver, etc. but then C have EnhancedDriver { struct Driver *dprt; ... } ...
tadzik "OO is when you do classes. Also, inheritance can help you with code reuse"
AAAAAA
brrt the only alternative is taking a god-overview to your program... which is feasible for small things 11:20
nine tadzik: oh yes, absolutely
brrt and OOP doesnt eliminate it
nine Btw tadzik, p6profiler-qt has been my most favorite tool in the past few weeks :) 11:21
FROGGS_ OO is about encapsulation and behaviour
tadzik Rob Pike's quote I also like
timotimo i wish we could give p6profiler-qt a bit more love. i wanted to build a view for GC runs, but it seemed like a boatload of work to build a "progress bar" with text in it into the table
tadzik nine :) I'm glad it's helpful
FROGGS_ I think that I quite rarely make use of inheritance btw
tadzik who would've thought that spending few days writing C++ on a Perl hackathon would do anything good :P 11:22
FROGGS_ hehe
FROGGS_ .oO( C deserves karma, rally )

tadzik this used to be funny when it worked 11:23
FROGGS_ since years
timotimo tadzik: are you interested in building a few more cool things into the p6profiler-qt? like, we're currently throwing away a whole lot of information the call graph could give us
tadzik :(
timotimo: sure
timotimo like "this routine is 90% jitted but 10% speshed-only. give me a list of the callers and how many entries are jitted vs speshed"
tadzik I mean, a feature parity with the angulailer would be a good start :P
oooh
this sounds lovely
timotimo or "this routine really deopts often. i wonder what callers are responsible for that"
nine Well getting a list of callers of a routine would be a great start anyway 11:24
timotimo right. and it should be trivial to do, too 11:25
this is one of the feature requests i have for coke's angular 2 rewrite of the html profiler
tadzik except for the part when you need to hammer your thoughts into Qt
timotimo ... yes
tadzik I can carry that ring to mordor though :P
timotimo that'd be fantastic
the qt model/view framework is a destroyer of my brain 11:26
when i don't have to work with it, i tend to be pretty darn pleased with qt
brrt hehehe 11:27

tadzik yeah, the complexity is mind-boggling 11:28

brrt or maybe i'm saying: i dont see which problems qt solves that tk does not 11:33
Woodi brrt: tk is hibernated in ugliness, that all whar is wrong with it...
timotimo "small script" :\ 11:34
Woodi maybe modules will cam later :)
11:34 CIAvash left
brrt i have very little experience with gui programming in general of course 11:35
tadzik I'm not knowledgable in Tk enough to give you a clear answer. IIRC as far as styling your UI goes, Tk is massively behind other toolkits, which is where the ugliness probably comes from
brrt so im literally being naive
11:36 pierre_ left
timotimo Qt lets you style most things with CSS 11:36
brrt hmm yeah. i dont really think Tk is ugly though
timotimo it doesn't have any rounded corners!!!! 11:37
brrt okay. so self-imposed pain on that front :-p
(i guess that shows how much i know about it) 11:39
11:39 poohman joined
tadzik :) 11:39
I think its tcl roots make its bindability a bit limited
even in python, tkinter would accept some code that "pure python", with its strong typing would not 11:40
timotimo yeah, tk is stringy-typed even in python 11:42
it's really bad we don't have a tk binding for perl6, it could be the killer feature

timotimo you can, however, copy an already built rakudo onto another system, if the paths are all the same 13:26

timotimo i tend to build my moarvm with -march=native, but that's not the default. that would probably break when you transfer from your home computer to an amazon cloud server thingie

DrForr I'm just testing it on 'is repr("CStruct"){ HAS int $x }' and that's throwing a warning. 15:25
(obviously a class) - If you know offhand what type I can use to get rid of the type warning that gives me I'd appreciate it. Not a big deal though. 15:26
timotimo yeah, HAS is for putting other CStructs into a CStruct
winfred_ hello all, what exactly does grep(&so) do? I googled it and could find only 2 instances - both in irc by moritz - does it remove gaps in arrays?
DrForr So I'd probably need to declare a CStruct class and *then * the HAS-using class. 15:27
mumble.
timotimo winfred_: it only lets things through that will boolify to True 15:28
it just uses the "so" sub as the matcher for grepping

bioduds panda install MongoDB failed 20:14
mst good 20:15
otherwise you might end up using mongodb
get DBIish and a postgres instance instead ;)
timotimo well, mongodb is still better than using /dev/null for writing and /dev/urandom for reading
bioduds mst : no other alternatives 20:16
moritz unless you really want random data :-) 20:17
mst bioduds: why?
20:17 canopus left
bioduds mst : I don't want RDBs 20:17
I want NoSQL
mst why?
bioduds cause I like them better
mst MongoDB is pretty crippled as NoSQL stuff goes
bioduds I agree
My first option is DynamoDB but it is expensive 20:18
mst personally, I'd go for storing JSON documents in postgres
you get the same querying capacity as mongodb
and it actually works
bioduds I always disliked RDBs, now that it is no longer the *only* choice, I'm happy :) 20:19
mst trout.me.uk/mongodb.jpg
bioduds not going back to them no more
mst disliked why/how?
bioduds schemas for instance 20:20
fixed
I really find it not good
NoSQL is shemaless
20:20 Cabanossi left
bioduds you may have different versions of data 20:20
mst right, which means it can easily accept broken data 20:21
bioduds not if you aggregate it correctly
mst MongoDB is 'your data is a giant chunk of JSON that may or mayt not make sense'
bioduds correct
mst Postgres, OTOH, lets you have validated fields (columns)
*and* JSON for stuff that varies
bioduds it is up to you to make it have sense I guess
mst and query into the JSON
personally, I prefer being able to have tiehr
same as perl6 has types but doesn't require you to always use them 20:22
but I don't find schemas hard
bioduds I don't find them hard, I find them wrong
mst need a new column? add two lines to a DBix::Class::Candy file, generate the ALTERs, apply to database, keep programming 20:23
20:23 canopus joined
bioduds if your model changes during dev 20:23
you need to re-make it
mst then that's trivial to fix
two or three lines of code
bioduds with nosql you dont
mst less code than I need to validate the nosql stuff
bioduds not if you already have millions of entries
mst well, yes, but then you have to make a decision about how to handle the eixtsing data *somewhere* 20:24
timotimo schemas aren't fixed
bioduds subsets are great for validation
timotimo good RDB systems allow you to modify tables
mst NoSQL lets you make the decision somewhere else
bioduds I am betting on subsets and nosql
mst but it doesn't get rid of it
right, so, again, use postgres and a JSON column
then you can have schemaless *and* a database that doesn't eat your data
20:25 Cabanossi joined
mst seems like the best of both worlds to me :D 20:25
bioduds nevertheless, I have no alternative in this thing I'm doing now
my "front" is Meteor
mst oh, and meteor requires mongo?
timotimo not even couchdb?
20:26 smls left
bioduds yep 20:26
I have used DynamoDB in other project
which is, I believe, ideal
but as I said, DynamoDB is expensive
and this project I'm working now must be cheap
mst github.com/Urigo/awesome-meteor#al...-databases 20:27
happily, meteor supports postgresql
so I return to my previous recommendation
bioduds but I don't like RDBs. I know it is strange to say it 20:28
mst ...
bioduds but the whole NoSQL paradigm seems so right to me
mst your only complaint so far is "I don't like schemas"
I already told you how to not need schemas
so what's the problem?
looks like there's also rethinkdb support
bioduds scalability
mst rethink looks kinda nice
postgres scales fine 20:29
I've replaced mongodb with postgres because postgres scales better more than once now
20:29 cbk_ joined
bioduds mongodb scales too 20:29
codefights is done in meteor
works great
mst ...
yes. you *can* scale mongodb 20:30
bioduds Meteor is awesome javascript framework
mst it's easier to scale a system designed by adults though
still not understanding what's wrong with meteor+postgres+JSON
no schema required. scales fine.
anything else?
bioduds cause I believe in mongodb 20:32
mst wat
bioduds i really don't think I need to go for postgres
which is RDB and I want to run away from it
mst you believe in a database that doesn't always return matching records for a query
ok
guess accuracy and data loss don't matter to you 20:33
fair enough
bioduds consistency
timotimo would go for redis under these circumstances
mst mongodb isn't
bioduds is not required for db system, it is a choice
geekosaur wat
bioduds my case, I don't require it
mongodb is not ACID
mst mongodb is for unstructured data that fits in RAM that you can afford to lose
bioduds not a problem for this project I'm doing 20:34
mst but at that point I'd use redis, yes
bioduds DynamoDB is ACID
I can choose developping and using it with consistency
but as I said, this project doesn't require it
you're making the assumption that all systems require consistency 20:35
they don't
some do, some don't
mst I'm not making that assumption 20:37
anyway, your argument at this point is "I believe in MongoDB" rather than anything technical
so, whatever, have fun
your religion is between you and your church, I try and stick to facts ;)
geekosaur considers nosql a failed experiment; increasingly the nosql folks are realizing that there's an actual reason for relational databases and adding the functionality back in, at least optionally 20:38
mst NewSQL 20:39
bioduds it's new, only needs to improve 20:40
but it is better in my opinion
geekosaur nope
bioduds roughly putting
geekosaur open source folks alwats want to believe the stuff that works is overengineered and they can do it better. years later they have rediscovered the hard way why it was done that way... and then the next generation believes it's overengineered and they can do it better 20:41
lather, rinse, repeat

bioduds I don't quite go with the crowd on that matter 21:21
it is reasonable to acknowledge that there is a problem that caused the need for developing non-relational dbs 21:22
a problem needed to be solved
it is being solved. surely there is a need for further improvement
geekosaur no, I don't think it did. the problem was "we thought slowness was just because stupid, we didn't think that maybe it's because people don't want their purchases dropped on the floor" 21:23
bioduds seeing this as an adventure of people who wanted simply to do something new is not reallistic
geekosaur if you want an unreliable data store, use a text file
bioduds it is, in my view, sticking to what exists for years because it exists for years 21:24
there are problems with this model for many huge role players out there
21:25 Cabanossi left
bioduds and that is why they came up with these new solutions 21:25
geekosaur yes, you always are doing something completely different
that's why nosql has been rewriting itself into newsql ever since it was creared
bioduds now, rejecting it on the basis that it is not as reliable as the old ones is, in my view, turning your face away from the problem and pretending it doesn't exist 21:26
geekosaur this was, very literally and explicitly, "it's just key-value, how hard can it be?" followed by years of "...oh"
it solves no problems
except the "problem" that rdbms was reliable

geekosaur you have not named a single problem it solves
bioduds respectfully, of course
scalability
I have
geekosaur scalability... what planet are you on
bioduds modelling after having huge data
re-modelling 21:34
these are real problems
geekosaur I grant postgresql has had scalability problems. rdbms in general does not
bioduds why didn't they make messenger in it?
geekosaur and keeps going long after every single one of your nosql solutions has encountered true big data
and failed 21:35
bioduds why does google have big data, then?
geekosaur because they don;t want to pay for oracle
bioduds it does not work with sql
omg, oracle?
geekosaur riiight
bioduds nope
geekosaur yes, its useless completely
bioduds same problem with oracle
won't handle petabytes of user data like they need it to
geekosaur right 21:36
bioduds no sharding
geekosaur dude, financial folks handle bigger data than you have ever seen
bioduds it is a need that came to solve scalability problems
you seem not to grasp that point, really 21:37
geekosaur somehow oracle scales to handle it when nosql falls on its face
I grasp it fine
I say your big data is small potatoes
bioduds well, facebook, google, yahoo, paypal, stripe, ... , * seem to disagree with you 21:38
21:38 firstdayonthejob left
bioduds otherwise, they would simply put oracle to do the job 21:38
geekosaur nom, they wouldn;t because they don't want to pay for it
timotimo oracle is hella expensive 21:39
stmuk the KV stores are ok to store cookies or throw away information on free systems
bioduds geekosaur : that is naive, man
geekosaur facebook google etc. are infamous for scrounging out solutions with cheap hardware
yes, you are painfully naive
timotimo and the way to find out how much you have to pay ... it's also hell
bioduds thinking that major players wouldn't go with the *best* cause it is expensive is naive, I believe 21:40
that is not how this game is played
stmuk data lost is acceptable for most facebook or google customers (they don't pay anything or have terms of service)

geekosaur it's all scrounging to build something quaireliable from the cheapest possible stuff 21:41
timotimo bioduds: in a world where people chant "worse is better", it makes sense not to go to oracle
also, when you start small, you'd have to have a crazy significant investment if you wanted to start with oracle 21:42
geekosaur google's pub;ished academic papers that say that right out as part of the problem they were trying to solve (for example figuring out a dirt cheap datacenter router without having to buy cisco)
AlexDaniel umm, I have a solution for you guys :)
bioduds well, anyhow, you are building these assumptions on stereotypes, I think.

geekosaur yes, history is nothing but a stereotype
experience is nothing but a stereotype
timotimo i wonder how strong proponents of object databases were about their opinions
bioduds and to be better than old-school DBs
my opinion
I may be wrong of course
and I respect all your opinions as well
:)
AlexDaniel just refrain from working on systems that are even slightest bit complex, so that you can always just use a file system and that's it
AlexDaniel hides
geekosaur watching youngsters throw out all the "stupid pointless" old stuff and then relearn the hard way over and over again why it was done that way, is something that has never happened and never will happen --- notwithstanding that you can ee it happening constantly, you habv deytermined it never will happen 21:44
stmuk is anyone testing much on *BSDs .. there is a report that installing panda on FreeBSD causes a moar core dump (which I've just seen on OpenBSD)

ok, now I'm in agreement, I think
timotimo so i'd want it to behave just like * ~~ any <c e> would

masak 'night, #perl6
AlexDaniel if some sane behavior was changed just like that, should I call it a regression? 22:23

AlexDaniel no, because otherwise it wouldn't have existed 22:24

BenGoldberg According to the docs, "Autothreading is what happens if you pass a Junction to a subroutine that expects a parameter of type Any or a subtype thereof (such as anything Cool)" 22:36
timotimo that's right 22:37
BenGoldberg Which means that *if* the $matcher argument of method .first were specced as an Any, or a Cool, etc, then the results that we are getting would be correct.
22:38 bjz left
BenGoldberg Except that $matcher is a Mu, and therefor autothreading should not happen. 22:38

synopsebot6 Link: rt.perl.org/rt3//Public/Bug/Displa...?id=129304
AlexDaniel bioduds: yes 22:47
bioduds okeydokey, just did
thanks
BenGoldberg Aha! github.com/rakudo/rakudo/blob/641e...s.pm#L1185 and github.com/rakudo/rakudo/blob/641e...s.pm#L1201 both have a parameter $test, which is not prototyped as Mu! 22:48
ugexe bioduds: if you read the error you see its OpenSSL causing the problem 22:53
and that you need to install openssl libs through your package manager
bioduds ok
let me try it 22:54
timotimo >_>
it spewed the error at you like five times
of course panda's backtrace for the "the test run didn't succeed" thing is pretty big and useless 22:55
bioduds code highlighting for perl6 in IDEs may become a challenge 22:59
I downloaded Perl Plugin for NetBeans and it is getting confused 23:00
with kebab case for instance
BenGoldberg .first fudgeup, now rakudobug-ed.
bioduds and also with unicode characters
BenGoldberg That's cause perl and perl6 are two differnt languages. 23:01
23:01 girafe left
BenGoldberg Although it should not be having any trouble with the unicode, as perl5 also accepts unicode source programs. 23:01
bioduds for instance, $prédio will stop highlighting on é 23:02
BenGoldberg bioduds, does your NetBeans thing comprehend any unicode at all? It might not have anything to do with the syntax highlighter, as such, and simply be a poor choice of tool.
ugexe it shouldnt be that big of a surprise that invalid perl5 syntax highlights funny using a perl5 syntax highlighter 23:03
23:03 firstdayonthejob joined
bioduds it is expected, for me. I believe it will be hard to have it corrected or even created for some IDEs i guess 23:04
since the whole idea is quite odd
BenGoldberg The following is perfectly valid perl5 code: use utf8; my $prédio = 3;
(and it's valid perl6 code, too)
bioduds yep
stops highlighting though
BenGoldberg If your syntax hilighter has problems with that, it's not *our* fault, but that of the author of the syntax hilighter. 23:05
bioduds kebab case also, for instance, $some-var stops highlighting on -var
BenGoldberg Find out who wrote it, and complain to them.
timotimo yeah, that part would be expected
bioduds sure, man, I'm just mentioning, I believe you are all interested in all that is going on related to Perl6 23:06
BenGoldberg $some-var is only valid perl5, and is not valid perl6, so it's not unsurprising that a perl5 syntax hilighter parses it wrong.
Err, tr/56/65/ :)
ugexe my $some = 1; sub thing { 0 }; print $some-thing 23:07
BenGoldberg Heh. But a proper perl5 syntax hiliter should display $some-thing with a different color for each of $some, subtraction, and thing. 23:10

ugexe the roll/pick not returning a seq with no args (which differs from .pick(1) .roll(1)) was said to be expected when i asked. so no arg tail doesnt match that 23:51
