lizmat pmurias: static content html is nicely handled By front-ends like Nginx , no ? 09:25
pmurias lizmat: I used the wrong words, by static content I meant dynamically generated html as opposed to sending data that is used by a client side js app 09:26
lizmat what's the difference between dynamically generated HTML and data sent to a client side js app other then the content-type ? 09:27
pmurias having some nice html templating integrated in? 09:28

sena_kun lichtkind, can you please provide some details? A link to your module repo, is it hosted on cpan or github-based ecosystem? 09:58
lichtkind sena_kun, Math::Matrix is still github only and since a Month there is version 0.25 and zef still gives me 0.20 10:00
sena_kun, but it was my suspition too that it is because im not on cpan
github.com/pierre-vigier/Perl6-Math-Matrix 10:01
sena_kun well, it shouldn't depend on cpan, I think. I'll look now, though cannot promise anything, unfortunately.
thanks
lichtkind, github.com/pierre-vigier/Perl6-Mat...6.json#L24 <- I see your META6.json has 0.2.0 as version, not 0.25. 10:02

sena_kun zef looks on META6.json when calculating meta data, so you should update it there. And then wait maybe just a bit(not sure how much though, but not a month, maybe an hour or something) and it'll be fine. :) 10:03

gaurav_ p6 seems to be a little sensitive to spaces. example: 11:14
sub ($x) - OK
but
sub($x) - NOK
sena_kun well, it is almost not sensitive, except for a couple of tiny bits.
gaurav_ okay. just trying to get the hang of it. 11:15
I have used perl5 extensively at work for many things.
11:15 imcsk8 left
sena_kun a space between `sub` and argument list is one of the exceptions, as it introduces ambiguity. 11:15
however, if you "I Know What I Am Doing", you can use Slang::Tuxic module/slang to get the ability to add space there. :)
gaurav_ Now I would like to see whether if there is a possibility of using p6 :)
wow @Slang::Tuxic, that is a cool option. Thanks sena_kunj 11:16

gaurav_ If I remember, 1-2 years ago one had to download rakudo and compile it, instead of a direct package. 11:24
sena_kun about standard linux distribution itself - well, right now I am doubting that. It is very tricky process and there must be serious reasons to do so. Linux community is very big, there are tons of various organizations and corporations behind it. As Perl 6 first release was not so long ago... Well. But you can always install it fine, there are repos and stuff. For tricky cases compiling is always an option.
things are better with time. :) 11:25
gaurav_ Yes, I can see that. It is absolutely great.
11:25 sotona left
sena_kun \o/ 11:25
gaurav_ Working at a bank, where all development is in Java, people just hate perl5 (dunno why!). Probably because they get scared of the perl5 expressive syntax. 11:27
I have to constantly hear stuff like, oh! perl5 is a dead language and blah blah..
11:27 aborazmeh left
robertle I guess staffing for java positions is easier than for most other languages 11:28
gaurav_ Java people can't look past Classes and Objects and when I read about Java, I now know why. Because Java only allows Classes and Objects - their brains have never seen functional stuff.
And the best part.. "oh.. you don't use an IDE? IDE is a must...!", I always vim 11:30
sena_kun well, people are not always like to learn new things, even if those things are good. so it's a matter of taste and bravery to help people learn by promotion, helping and creating amazing things.
.o0 ( and we have a Perl 6 IDE, in beta though :D )
robertle still, you can write some fine stuff in java, and the relatively simple language makes is readable for people less proficient 11:31
gaurav_ Yes, I read about that. It is more than welcome!
Yes, Java is OK or probably good if it suits the development goals of the organization/company. But when their developers start the negativity about other languages, it just doesn't make sense. 11:32
pmurias IDE help a lot when writing java stuff tho 11:34
gaurav_ @pmurias, I am sure that is the case. this may be the reason that no one is without an IDE ;) 11:35
AlexDaniel gaurav_: re “standard linux distribution” github.com/perl6/user-experience/i...-413646915 11:38
gaurav_: i.e. most distros already have rakudo
robertle I guess the weird enforced directory structure also makes worrking with vim or so hard, at least for me. 11:39
AlexDaniel though it depends on how recent your distro version is
gaurav_ @AlexDaniel. Checking link. Thanks for it.
robertle in any case, the success of java is really interesting. it's not because of anything java did by design. in fact noone is using java for what it was designed for 11:40
sena_kun AlexDaniel, I thought he meant en.wikipedia.org/wiki/Linux_Standard_Base
s/he/they/
gaurav_ @robertle. enforced directory?
robertle but somehow they have managed to form a community with shared ideas on how java code should look like
AlexDaniel sena_kun: oh… oh… 11:41
robertle gaurav_: the package = directory plus the convention of having the com/something/mycorp prefix to make all packages globally unique. makes the package tree really deep
I think this normative process makes it really easy to get people to start on other codebases, and therefore a good language for corporate development. you can move people around easier 11:42
of course the flipside is that java can't evolve easily, and that is showing at the moment
gaurav_ robertle: Is that the reason Java8 is now trying to do functional programming? 11:43
robertle but it's interesting that the C++ community is doing more of that recently, working towards a less fractured idea of what code should look like. at least that is my impression
gaurav_: I'd rather think the functional parts are one of the rare cases where java has managed to evolve. it's not like that only perl is combining functional and imperative programming, everyone is 11:44
11:44 lizmat joined
robertle and from a lisp or scheme point of view all of these attempts are relatively weak 11:44
AlexDaniel 8? don't we have java 10 now? :) 11:45
though I stopped following it at 8, so I don't even have a clue about 9 and 10
11:45 p6bannerbot sets mode: +v lizmat
robertle the actual changes to the language are relatively small 11:45
gaurav_ Not sure about Java 9 or Java 10. 11:46
robertle the only thing i really noticed was c++-style type inferrence at compile time
and technical improvements to the garbage collector 11:47
AlexDaniel oooooooooo `var` in java 10! Finally!
robertle the other bit I find interesting or even worrying is that at my work, java is slowly being replaced with golang, an even less expressive language. and one that is even more monoculture in how code should look
AlexDaniel I've been using `val` from projectlombok since forever. Nice to see it becoming part of the language 11:48
gaurav_ @robertle: which sector of industry do you work in? 11:49
11:49 tejr joined, p6bannerbot sets mode: +v tejr
robertle gaurav_: used to be television, now fitness. but in both cases it's just backend development. some of it was C++ and java, now it's java and golang. some scala by accident 11:52
11:52 saki joined 11:53 saki left
robertle golang is just barbaric, and java has these weird cultural things where you need to have so much useless structure in the form of interfaces and facades around. I don't really like either. C++ lacks good libraries for typical backend work, and (like perl) it requires restraint from the developer, but at least it's fun 11:54
gaurav_ I work in Investment Banking firm in Testing/QA division. Our new products are now moving from Java to Scala
robertle scala is a much saner language than java, but I wonder whether it will hold 11:55
gaurav_ But in our case, they are using Scala in conjunction with Apache Spark and Hadoop framework. The volume of data is just too much. 11:56
11:57 leastbit joined, leastbit left 11:58 psychoslave joined, saki joined, saki left, p6bannerbot sets mode: +v psychoslave
robertle I guess that is the other reason for java or scala: momentum by all these big frameworks 11:58
gaurav_ One thing about C++ is that you need to have a discipline and patience. It takes some time to learn it, specially if you know a scripting language and trying to do c++. 11:59
Yes robertle. It is only due to these big frameworks. Otherwise I haven't had the time to look into scala to know what it brings on the table. Someday I shall do it. 12:00
robertle yeah, it's a bigger language. but I think the more important aspect, and perhaps more relevant for perl, is that you need to have discipline *during* development, not only in the startup/learning phase. it's just way too easy to do something unnecessarily complex. you even get the excuses, "zero overhead" and all
gaurav_ One thing I like about C/C++ is that you can compile your code and hide the code. Try to understand that there are a lot of people who are just looking to copy your work and present it as your's. 12:01

ingy Hey all. As I've been running the same test suite over and over for the past months it seems like the perl6 tests keep getting slower and slower. Is there some kind of caching going on outside of testing directory, that could somehow be causing a problem? 14:58
I mean I can clear my local .precomps etc, but is perl6 writing something else out somewhere, that it is later checking causing it to slow down more and more 15:00
mst can't think of anything except precomps but that doesn't mean I'm right 15:01
timotimo perhaps the precomp folder is filling up with outdated bytecode files? and finding the right file takes longer for some reason? i don't know how it works ... 15:03

mst since ingy's not explained what his test suite does, "I bet it's the precomps" plus trout.me.uk/vaguecat.jpg are my only answers atm 15:12
robertle don't fully understand precomp, but I don't think there is any "scanning" involved. so more files should not really make it slower apart from the OS parts of course 15:13

ingy [Coke]: it's exact 15:41
15:41 gaurav_ left
ingy but it feels like that :) 15:41
[Coke] is the whole thing slowing down? or just a subset of the tests? 15:42
you're updating rakudo as you go?
ingy gist.github.com/d3e9d633d8e6bd136a...298f52f1c5
I'm going to plug in my laptop and see what diff it makes 15:43
timotimo wow, almost 1 minute of system time 15:44
that's impressive
ingy over 1 minute with precomp
I mean before -e .precomp 15:45
`make clean` deletes precomp...
timotimo is this the same thing i get when i git clone your testml repo from github?
ingy timotimo: sure. you should be able to `make test-runtime-perl6` 15:46
timotimo is it testml-pm6?
ingy no
I should get rid of that :) 15:47
timotimo so testml1-pm?
ingy testml-lang/tesml
testml-lang/testml
timotimo ah
ingy I have some power saving stuff turned on for linux. wonder if it slowed things down. but last week in glasgow wasn't this bad. don't think I was always plugged in. 15:49

ingy 2 secs seems like what I used to get

timotimo how filled is your ram? and hard drive?
ingy how do I check ram?
timotimo i usually look at htop, but "free -m" is good enough 15:54

timotimo so the postrelease opts don't actually do all that much, except when it has to precompile in which case it's more expensive? 15:57
wait, did i read that backwards 15:59
OK, postrelease-opts made it about 5 seconds faster when you have "make clean" before that
except now i got 35 seconds after make clean; perhaps because i just recompiled moar and rakudo cleanly 16:00
as always: timing stuff is fiddly
ingy what's postrelease-opts?
jnthn ingy: A MoarVM branch with a bunch of new opts, which we'll merge to master soon after the next release. 16:01
timotimo everything jnthn has been doing in the last ~two weeks; things that shouldn't go into the release because it's too risky
ingy: how do i run a single test file "directly" with perl6? 16:03
i'd like to remove "prove" and "make" from the pipeline
ingy timotimo: I like your explanation more that jnthns :D 16:05
timotimo: give me a sec... tricky
timotimo that's not good :D 16:06
ingy it's fine 16:10

i just added the path for my perl6 binary in the line and it works now

it's something outside of p6 that only happens when testing p6
timotimo that one runs in only 0.23 seconds or so, so not a good target for benchmarking 16:34

I think the cli param for rakudo could be a nice option tbh

put that definition into a module and use -Mpragma::num 16:42

of course it only works for constants in that very file

in some cases, I got something like Attempt to return outside of immediately-enclosing Routine (i.e. `return` execution is outside the dynamic scope of the Routine where `return` was used)

jnthn xinming: return binds to the enclosing routine, not block; if you want to use return, you'll need an anonymous sub instead of an anonymous block. If you're in a loop, you can also use `next` to go to the next iteration. 21:06

ingy I figured out the p6 sloooowness 21:56
timotimo pong
what was it?
ingy it might be considered a bug
try: time PERL6LIB=/home perl6 -e 'use NativeCall' 21:57
timotimo aaaaahahahaha
yeah, that's not fast
ingy it explains a lot. I keep all my source repos in ~/src 21:58
timotimo having PERL6LIB set to ~ or even ~/src doesn't work very well either
ingy and that ended up in PERL6LIB (bug on my part)
but ~/src got bigger each week
timotimo what do you suggest we do about it?
ingy so I wasn't imagining the p6 tests getting slower 21:59
timotimo unsolicited warning output about folders way too large to be useful in PERL6LIB would be kinda weird
ingy well I had: PERL6LIB=good,also/good,bad/and/big 22:00
bad/and/big was never needed for a look up
do you do a parallel lookup or something?
timotimo you don't "use Test" or something? 22:01
i believe PERL6LIB comes first
ingy I see
timotimo so if you use Test or NativeCall or something rakudo has in its lib/ you'll end up going through your whole PERL6LIB before looking there
ingy before core
aye
ok
timotimo and doing lookup in parallel won't help much because the earlier ones have to come up negative before a later one can be accepted
ingy I wasn't suggesting parallel was good 22:02
timotimo OK
ingy I forgot that stuff would get looked up in ~/src at all
but now I understadn
so nothing to see here... 22:03
except... hmm
I only have 42 repos in ~/src
seems like should only be 42 stats 22:04
but takes 13 secs
timotimo it's going through the whole tree
deeply recursive
ingy why?
timotimo not sure
ingy no thing FOOLIB would do that
no other FOOLIB would do that
timotimo github.com/rakudo/rakudo/blob/mast...m6#L61-L93 22:05
ingy looking up Foo::Bar under $LIB would just stat $LIB/Foo
so I'm wrong, only 1 stat not 42 :)
timotimo i'm not sure who calls the id method there 22:06
ingy I guess p6 lookup is supernatural
timotimo gist.github.com/timo/a8bef611712d2...de65aefc08 22:07
here's a stacktrace for you
ingy seems like a big local lib could also slow things down
timotimo github.com/rakudo/rakudo/blob/mast...y.pm6#L104 22:08
this requires the ids
22:08 graphene joined
timotimo OK, so here's the rub 22:08
if you load Test, it'll have some dependencies listed
22:09 sena_kun left, p6bannerbot sets mode: +v graphene
timotimo hm 22:09
maybe this is how it is:
ingy I wonder if a `use lib` would be faster than a PERL6LIB
timotimo the first entry in the PERL6LIB is where all precomps are stored
ingy ok
timotimo it should do the same thing 22:10
if something depends on precompiled files, it first checks if the repo has not been touched at all
and the file repo does that by sha1-ing all files
ingy one would expect them to be the same, but p6 is always too magic :)
hrmm 22:11
timotimo github.com/rakudo/rakudo/blob/mast...agement.md - maybe this has the explanations
PERL6LIB on a folder with pm files isn't really what you'd have in production
you'd have it actually installed properly
ingy sha1ing all files seems...
timotimo: what would PERL6LIB be in prod? 22:15
timotimo ""
ingy oic
timotimo or something like inst#/path/to/an/installation/folder
ingy is that folder a .precomp dir? 22:16
timotimo not quite
