rangerprice Perl 6 will have more features than Python ? 00:06
skids Heheh. We don need no stinkin basics. 00:09
skids cannot speak to what constitutes a "feature", or Python 00:10
flussence African or European python? 00:12
rangerprice Hahahaha
00:12 raiph left
rangerprice Another question, Perl 6 will have a increased speed performance ? 00:13
flussence increased relative to what?
rangerprice relative to Perl 5
00:14 raiph joined 00:15 laouji joined 00:17 aborazmeh joined, aborazmeh left, aborazmeh joined
skids I think currently the answer is it depends on how many frameworks/modules you usually load into Perl5 to get things that are builtin to Perl6. 00:20
timotimo it depends drastically on what you're doing 00:25
if you have a very tight loop with numeric code and you use native integers, you can be quite a bit faster with rakudo + moarvm or rakudo + jvm
if you're doing something that parallelizes well and you have enough cores, you can end up faster than perl5 by a bit
the GLR will, once finished, improve performance related to lists quite a bit, which makes me quite excited every time i think about it :P 00:26
00:26 raiph left
timotimo other than that, you'd really have to go on a case-by-case basis 00:27
i haven't done a run of the full benchmark suite in a long time 00:28
rangerprice Today perl 6 is a general purpose language. But why perl 6 is not specialized into a specific purpose ? like speed performance, concurrency, or system administration ?
timotimo and tux's Text::CSV stuff is always noticably slower in the perl 6 version compared to the different perl 5 versions :(
that's not the perl way :)

timotimo i feel like i've forgotten a bunch of stuff, but that feeling's always there anyway 00:57
zef takes quite a bit longer to install than panda does :P 01:03
dnmfarrell Hey all I'm trying to create a pseudopod grammar with an "=include" token that has a filepath to another .pod file. I want the grammar to parse that pod file and insert the match object to the current parse tree. Is that possible? Here's what i've got so far: "token include { ^^\=include \h+ <singleline_text> \n { $/.make(self.parsefile( $/<singleline_text>, :actions($*ACTIONS) )); } }"
timotimo huh 01:04
arnsholt I'd do it as an action
timotimo ugexe: i didn't end up with a "zef" binary in the folder it's supposed to end up in
you may want to .ast after the ) belonging to parsefile
oh 01:05
you want the match object
that's okay then
arnsholt Just an action method for the include directive, which can "make PseudoPod.parsefile(...)"
dnmfarrell arnsholt: but the action method is more to do with transformation pod --> html, pod --> markdown etc. The "include" directive is part of the grammar 01:06
arnsholt Aha, in that case I don't have any terribly good ideas 01:08
dnmfarrell I guess I could do it that way, but then i'd have to have the "include" action class everywhere I used the grammar. Hmm, maybe that's a pragmatic way forward...
arnsholt Except maybe factor it so that you can use the actions to build the AST, and have a separate AST transformer to convert it to different formats

ShimmerFairy dnmfarrell: are you aware of the P<> formatting code? It's meant to embed things into a Pod file, like standardized copyright info for instance. If you want to make something like =include , you could possibly look into spelling it as P<> 01:37
dnmfarrell ShimmerFairy: no I'm not, P<> is a Perl6 pod formatting code? 01:39
ShimmerFairy It would have the advantage of being compatible with regular Pod6, if nothing else :) (though rakudo's current parser doesn't support it, sadly)
dnmfarrell ah
ShimmerFairy dnmfarrell: yes, you can see here: design.perl6.org/S26.html#Placement_links
dnmfarrell I wonder why it's a formatting code and not a command block. That could create issues if it pointed at a pod file containing command blocks but it was in the middle of a paragraph 01:41
I guess you could inject blank lines 01:42
ShimmerFairy dnmfarrell: it is interesting, I'll admit, but I think the idea is that it's the "opposite" of a L<> code; instead of pointing you out of the document, it pulls something into the document.
01:42 dayangkun joined
dnmfarrell Yeah, very curious, thanks for the link! 01:42
ShimmerFairy dnmfarrell: the example S26 gives for P<> isn't formatted very clearly, but putting P<> as its own paragraph is exactly what's demonstrated
You're welcome. I don't know for sure what your plans are with =include, but I just wanted to point out that something like what you were going for is already specified in the design docs :) 01:43
dnmfarrell I'm writing a pseudopod extension for Perl5 pod github.com/dnmfarrell/Pod-Perl5/bl...Grammar.pm 01:47
ShimmerFairy And for what it's worth I think a directive would be clearer (though I guess the more Perl6-y name would be =use :P), however P<> seems harmless enough to let stay in the spec. (P<toc:> for a table of contents looks especially useful)
dnmfarrell: interesting, is it an extension for Pod6 or Pod5? (pseudopod, looking quickly, is for books and such, right?) 01:49
If Pod5, interesting choice writing it in Perl 6 :)
dnmfarrell Well version 0.1 was in Pod::Pseudopod, 'twas a painful experience 01:50
Pod::Simple literally has a module called "black box"
Writing it in Perl 6 was just so much easier. But now I want more features, hence the extension :) 01:51
ShimmerFairy dnmfarrell: well, if you're ever adding a Pseudopod-like thing for Pod6, I'd be interested. I'm actually in the middle of writing a replacement Pod6 parser for rakudo (not public yet, but hopefully soon), so Pod6 design question will be on my mind for a while :) 01:52
*questions
dnmfarrell Interesting ... maybe I should just use Pod6 :) Is there much left to implement of the spec? 01:53
ShimmerFairy dnmfarrell: unfortunately, I would say so. P<> like I said isn't supported, and neither is M<> (M<> is a tag meant for modules to plug in whatever formatting code they want, e.g. M<mymodule:stuff> is meant to generate a specific class with "stuff") 01:54
dnmfarrell: If you want to play around with Pod6, then it's perfectly fine. But if you have Serious Documentation™ in Pod5, I wouldn't fully switch that stuff over just yet. 01:55
dnmfarrell ShimmerFairy: thanks for the info. I'm going re-read the Pod6 spec, I think there are some ideas I can borrow for my project :) 01:57
ShimmerFairy Looking at the Pseudopod tutorial, that T<> tag for citation would be implemented as M<citation:my-source> , as an example.
dnmfarrell: it's worth a read for sure :)
Also, G<> and H<> would be M<sup:> and M<sub:>, respectively. The idea of the M<> is that M<Foo:stuff> would generate an object of type Pod::FormattingCode::Named::Foo, in case you're curious :) 02:00

jnthn good...whatever time this is...#perl6 :) 03:17
yoleaux 19 Aug 2015 19:06Z <nine> jnthn: what is .flat actually supposed to mean? Array has a flat method that does Seq.new(self.iterator) while inheriting .iterator from List. List itself on the other hand does not use its own iterator for .flat and inherits Iterable's instead.
03:17 cognominal joined, aborazmeh left, CQ left 03:18 CQ_ is now known as CQ
jnthn .tell nine because an Array is a bunch of Scalar containers, we know that nothing will ever flatten, so instead of type-testing everything against Iterable we simply just give back an iterator over the values (and if you use binding to defeact that and put an Iterable directly in there, on your own head be it) 03:19
yoleaux jnthn: I'll pass your message to nine.
03:26 laouji left
skids jnthn: should Array not allow BIND-POS of uncontainerized things then? It's been unclear to me how strongly it polices Scalars, whether that was always or just via the iteration related APIs. 03:35
abaugher I have a hash that's hitting my RAM limits. Is there a way to tie a hash to a file, like the old dbm routines or DB_File? 03:36
jnthn skids: It doesn't police it that strongly. 03:37
skids: We've long had := as being fairly low level 03:38
skids: The only place it enforces it is assignment.
skids OK.

is there a way to rebless? 10:46
ShimmerFairy jdv79: I don't know P5 refs, so I don't understand that terminology enough to help. Best I can guess is that "is copy" instead of "is rw" lets you change SELF as though you had copied it.
jdv79 i imagine not as it would require uncomposing which is probably impossible

[Coke] trying to update the daily run scripts to use Inline::Perl5 so we can report on those also. panda bootstrap hanging here: Compiling lib/File/Find.pm to mbc 14:43
(cloned panda into ./panda - cd panda && ../install/bin/perl6 bootstrap.pl)
also, when it says fetching File::Find - is it really fetching, or using the copy in ext/ ? 14:44
14:44 jack_rabbit left
nine [Coke]: I changed line 40 in t/harness to +$ENV{'PERL6LIB'} = join ',', qw( lib . /home/nine/Inline-Perl5/lib ); 14:44
[Coke]: to run S01 spec tests
laben [Coke]: the one it builds and installs is the one fetched from git, the one in ext is used only for making included panda work OOTB 14:46

[Coke] Ugh. Want to have a way to build without re-fetching things over the network all the time. (already doing this for rakudo, roast, pugs, nqp, moar, parrot, etc.)
anyway, the panda install is busted for me on that setup. Will try nine's trick of using an uninstalled copy, but I'd rather test the install while I'm doing this. 14:49
JimmyZ what about zef?
laben [Coke]: also, for now File::Find Shell::Command and Panda need to have patches applied to them to work on glr, you can find them in PRs in their repos 14:50

timotimo praised be oetiker+partner!
PerlJam Did someone court Oetiker+Partner for the donation or was it "random"?
timotimo since they are based in olten, i bet they have something to do with the SPW 15:07
PerlJam ah
timotimo in fact, they are one of the sponsors listed on the spw website
[Coke] laben: starting with github.com/coke/perl6-roast-data/b...ar-jit.sh, modifying that to grab panda, inline-perl5 ... it's a bunch of small change to that script, but basically, doing a make install, then using the installed perl6 to run panda hangs on teh aforementioned step.
nine [Coke]: if you're on Linux, just run this from your Inline-Perl5 directory: gcc -Wall p5helper.c `perl -MExtUtils::Embed -e ccopts -e ldopts` -shared -o lib/Inline/p5helper.so -fPIC -g
[Coke] nine: "just" ? 15:08
I'll make panda work instead.
nine or that :)
timotimo oh wow

nine wow indeed
leont nine: do you always build it with ldopts? 15:10
nine leont: that's what perlembed told me to do
leont It's meant for executables, not shared objects. It's probably ok, there is a chance that has some consequence on some platforms.
laben [Coke]: did you try rakudobrew to help install and manage both rakudo and panda? 15:11
[Coke] laben: no.
oetiker bow gracefully 15:12
lizmat oetiker++ :-)
[Coke] I'm specifically doing this for the daily spec test run, which already has a build setup (does rakudobrew provide a way to build from local checkouts rather than fetching over the network?)
oetiker++
PerlJam oetiker++
nine oetiker++ # counter is far behind
tony-o is there actually a counter? 15:13
laben i would recommend, it makes keeping up with commits very easy and simply keeps the git repo around, so no big fetch every time
nine leont: without it I get Unhandled exception: Cannot locate native library 'lib/Inline/p5helper.so': lib/Inline/p5helper.so: undefined symbol: boot_DynaLoader
tony-o: probably not :)
lizmat [Coke]: it is one of my goals to allow Installed modules to be re-precompiled when rakudo changes
PerlJam tony-o: only in our collective consciousness :)
lizmat without needing to refetch them from anywahere
*anywhere 15:14
ugexe zef keeps the repos around in /tmp/module-name and does a git pull if it exists already
leont nine: yes, it certainly contains essential things, it will also contain useless things (you don't need most -l flags except on Windows/Cygwin for example), it may contain harmful things.
Not saying it's wrong, I'm saying it may be subtly wrong somewhere.
nine that's the worst kind of wrong... 15:15
ugexe lizmat: ive been thinkg how to do that as well, mostly boiling down to saving the dependency graph in the MANIFEST
oetiker at O+P we love perl ... most of our tools are made with perl ... so we thought that it would make sense to invest a bit into perl 6 ... especially hoping that other small shops would maybe follow our lead
15:15 diana_olhovik_ left
tony-o i only love perl6 15:15
_itz_ oetiker++ # I've used rrdtool many times over the years 15:16
ugexe and possibly a way to re-run the hooks/ (as well as saving the hooks)
leont It's probably nothing, I'll try to look into it when I have time
tony-o is the hooks thing still the biggest challenge with that? a lot of BUILD.pm junk still out there 15:17
lizmat ugexe: as a core developer, re-installing modules should be possible without network access, every time I to "make install"
tony-o lizmat: if pull fails it tries to build what is there
ugexe lizmat: right. if the manifest contained a dependency graph then it would be possible
lizmat tony-o: I don't want it to try: I don't want modules changes as well whenever I do a make install of rakudo and I happen to have network connectivity 15:18
nine Oh that's a cute one: adding debug output to deepmap makes many more hyper tests pass
tony-o lizmat++
timotimo so you're potentionally sinking something that didn't get sunk before? 15:19
nine timotimo: .perl reifies the list. deepmap(\op, \obj) really requires obj to be a fully reified list. It's accessing $!reified directly 15:21
timotimo ah, mhh
skids agrees strongly with lizmat++, was actually perturbed to discover build/test targets bailing for lack of net. 15:22
moritz \o 15:23
tony-o skids: i think lizmat is more referring to when recompiling a bunch of modules all at once, those modules shouldn't be automatically upgraded to a new(er) version if available. just recompile the ones already available in the system
lizmat tony-o: indeed 15:24
tony-o i'm taking yours to mean that build/test stage should fail if the module requires net but it isn't available (skids)
nine oetiker: maybe I should try to sell it as an investment to our mangement instead of as a donation. We are donating, but more tranditionally to social institutions.
JimmyZ oetiker: thank you! 15:26
lizmat
.oO( the new trend in mangening :-)
PerlJam nine: how would you do that? You don't typically expect a return for donations, but you do for investments. What would their ROI for Perl 6 be? 15:28
lizmat ROI could be in personnel enthusiasm for work 15:29
mst but also in potentially increased development speed
skids tony-o: the general principle of the matter, really. It's ok to quickly check for updates and notify the builder they are available, but you don't want code changing automatically when you are debugging stuff, and definitely don;t quit because your git pull failed.
nine PerlJam: it would be a long term investment, that's for sure. Well, keeping Perl alive can only be a good thing when you sit on a quarter million LOC Perl code.
PerlJam lizmat: that might work for nine, but I'm not sure it would work for "management" :)
mst 'spnsorship' is often an effective term
skids
.oO(kids these days. When I was a kid you had to walk 25 feet up a flight of stairs to get your sibling off the phone before downloading anything.)
 15:30
tony-o skids: i believe that is what lizmat was hinting at, the default should be not checking for updates when rakudo version changed from the last one. zef doesn't die if the git pull fails
s/hinting/stating/ 15:31
PerlJam nine: what mst said too
skids tony-o: Right. I would say as long as the timeouts are kept short, though, it's OK to quickly look and spit out a "hey there are updates, btw" message. 15:32
ugexe the build process will get better as CURLI matures and the manifest contains more meta information
lizmat ugexe: indeed :-)
[Coke] skids++ #old timer.

for now, i will follow my own advice and go to bed early, for once 21:09
good work | rest #perl6

nine Woah! Only 189/1047 spec test files failing now. Good work people!
FROGGS my commit to roast did not show up also
189? really?
197 test files fail on my box 21:23
nine Including my latest commit?
FROGGS ohh, perhaps not, no
nine That would rescue my evening if I fixed 8 files with that :)

timotimo How about that bump for moar and nqp revisions? 21:25
FROGGS nine: and I potentially made three more pass with an upcoming commit :o) 21:26
timotimo: yes, we need to do that
timotimo I am without development machine at the moment 21:27
nine I get 198 failing without my commit
timotimo Though I could turn the laptop on for an hour or so

RabidGravy the software fairies are smiling on you 21:47
nine FROGGS: well .perl on an an itemized empty hash would print ${} which triggers a worry about using $() in Perl 6 instead of ${} while {}.item doesn't and should mean the same, shouldn't it? 21:48

rangerprice Hi 22:09
vendethiel o/, rangerprice 22:10
rangerprice So, why Perl 6 has not metaprogramming features ?
vendethiel rangerprice: it has tons of them 22:11
rangerprice serious ?
vendethiel rangerprice: yes. meta-programming for objects, macros, lexical scope, etc 22:12
rangerprice Perl 6 is an homoiconic language ?
vendethiel m: sub f { g(); }; sub g { say callframe(1); }
GLRelia ( no output )
camelia ( no output )

vendethiel no, not homoiconic. Lisp isn't the only language with macros ;) 22:12

ugexe in a hash of array of hash/array etc (like projects.json for instance) is there a short and sweet way to find any instances of a specific key, any number of levels deep (but if it makes it easier, always at the end node), without knowing the exact structure of arrays and hashes? 22:19

vendethiel ugexe: something like this? :)
22:24 TEttinger joined
vendethiel I guess that doesn't work past one level, uh 22:28
ugexe yeah :( 22:29
rangerprice It would be great if perl have native c++ code integration in syntax
leont Good luck with that!
vendethiel rangerprice: that simply wouldn't be parsable. if your usecase is c/c++ code interop, nativecall is good at this
ugexe i was hoping there was a way to abuse antipairs or something to turn the hash inside out 22:30
RabidGravy except for the c++ name mangling part
vendethiel ugexe: there might very well be! i'm not versed into anti-pairs 22:31
leont RabidGravy: and its typesystem, and a bunch of other things
vendethiel leont: just think about name resolution! and ADL
rangerprice venderthiel : what metaprogramming features has perl
leont ADL will be fun too, yes
RabidGravy trivial to make a C wrapper of a C++ class in such a way the perl can use it
22:32 AlexDaniel joined
vendethiel rangerprice: you can use "tab" to autocomplete my name :) 22:32
rangerprice: as I said: MOP for the objects, macros, callframe()-style, etc.
rangerprice: the debugger is written only in perl6 code.
rangerprice oh 22:33
vendethiel here's teh debugger: github.com/jnthn/rakudo-debugger some metaprogramming code that adds a "monitor" keyword: github.com/jnthn/oo-monitors
RabidGravy at various times in the lifetime of a program yoy can get access to and modify the behaviour and meta data of nearly all the meta objects 22:35
what you do to them is obviously down to the program design 22:36
see also github.com/jonathanstowe/Staticish which takes some awful liberties with class composition to make a "static" class 22:38
rangerprice Why Perl is a hight level programming language and not a mid-level ? why perl has not C keyword like: const, static, constexpr...to produce a more optimized perl code ? 22:41
vendethiel static isn't related to optimization 22:43
constexpr is akin to our BEGIN/constant
const is "just" immutable data things in perl
RabidGravy it is optimised, but for programmer and design efficiency in mind rather than succinct machine code generation 22:44
"post-modern" - they've been banging on about moores law for years let's use it to make software developers lives happier 22:46
rangerprice okay, if perl can be optimized without an equivalent of the tons of keywords provided by C, why C need all this tons of keywords to produce optimized assembly and perl not ?
22:47 virtualsue left
RabidGravy because perl doesn't make assembly (it could if you cared to make it happen of course) 22:47
22:48 skids joined
rangerprice oh 22:49
oh i understand now
lizmat .tell [Coke] re github.com/perl6/roast/commit/0452...5bf2e7f183 I have *no* idea, I just reran the generate script 22:51
yoleaux lizmat: I'll pass your message to [Coke].
RabidGravy perl 6 is just a specification, the specification indicates that it will run on some virtual machine, the nature and implementation of the VM is a separate matter
lizmat .tell [Coke] I assumed it to be a hash ordering thing
yoleaux lizmat: I'll pass your message to [Coke].
22:53 danaj left
cognominal rangerprice, in modern language most optimization is moved at the runtime. The runtime gets more info than the programmer and static optimizers can dream of. 22:59
And the time spent doing dynamic analysis is recouped by the optimisation produced except for very slow processors. 23:01
rangerprice oh
vendethiel ...in theory, at least ;-) 23:02
vendethiel looks at SufficientlySmartCompiler
cognominal This has been pionnered by the Self language, used by Hotspot Java and now every javascript interprer.
vendethiel 's not sure he'd use "self language" rather than "whichever VMs the great engineers built" :P. didn't IBM sell self and all, back then? 23:03
cognominal rakudo has most of the infrastructure to do it, but is not quite there yet.
self was a resarch language at Sun Microsystems. I think you can trace the self engineers moving from self, to java, to javascript and Go :) 23:04
And then, there are the self taught people like jnthn :) 23:05
speaking of languages, I noted on #perlfr that Perl is rococo when the tendancy is now neoclassic like go :( But TimToady would argue that Perl is postmodern, not rococo. Things are there for a reason. 23:08
RabidGravy Yeah I'd go with post-modern too 23:09
cognominal well, that was an architectural pun, where neoclassic comes after rococo baroque :) 23:10
And go is definitevely neoclassical. 23:11
23:12 lizmat left
RabidGravy yeah but taken to the concrete extreme it would imply that perl (rococo) is a sentimental re-imaging of the pre-classical (e.g. cobol) 23:13
23:13 jkva joined
RabidGravy which clearly isn't the case 23:13
metaphor not pun
cognominal yea 23:14
RabidGravy :)
23:15 leont left 23:17 jkva left
RabidGravy of course the problem with the whole analogy set is that in architectural (and indeed the arts generally) we're talking timescales of hundreds of years, in programming at most tens of years 23:24
TimToady now at YAPC::Asia venue 23:28
RabidGravy yay! 23:29
cognominal RabidGravy, we could do a mapping like does Sagan with his cosmic calendar. There is clearly an event acceleration at the end and maybe some more complexity. 23:30
With the VM fashion, there is clearly the equivalent of endosymbiosis going on in the computer world. And that brings Sagan's wife, Lynn Margulis, in the picture :) 23:33
