TimToady no :) 00:18
sjn confusing, eh
camelia rakudo-{parrot,jvm,moar} 28d672: OUTPUT«(timeout)»
TimToady [+]() is just like foo()
sjn it is? o_O
TimToady reductions are exactly like list operators, including the rule that parens make it a function call 00:19
sjn when would you want to call a reduction operator as a function?
TimToady when you want to something else after as a postfix 00:20
timotimo m: say [\+](1, 2, 3, 4, 5)[^2]
camelia rakudo-moar 28d672: OUTPUT«1 3␤»
timotimo m: say [\+] (1, 2, 3, 4, 5)[^2] # as opposed to this
camelia rakudo-moar 28d672: OUTPUT«1 3␤»
TimToady well, you lucked out :)
timotimo ... er
timotimo is quite tired, it seems 00:21
colomon … er indeed
TimToady you see the difference with the infinite list, what with [+] being somewhat more eager than [\+] 00:22
m: my $pair = (<this is>, <a list>, <of four>, <sublists>) => "Or is it?"; say $pair.key; 00:23
camelia rakudo-moar 28d672: OUTPUT«this is a list of four sublists␤»
sjn is new to [+] too :-\
TimToady earlier, it was implied that these lists flatten in the key
they don't
m: my $pair = (<this is>, <a list>, <of four>, <sublists>) => "Or is it?"; say $pair.key.perl
camelia rakudo-moar 28d672: OUTPUT«$(("this", "is"), ("a", "list"), ("of", "four"), "sublists")␤»
TimToady see, the structure is still in the key
colomon oh! I missed the \
TimToady m: say [\+] 1,2,3 00:24
camelia rakudo-moar 28d672: OUTPUT«1 3 6␤» 00:25
TimToady note that it returns the same # of values, hence the [^2] worked either way
despite doing the operations in the opposite order
why I said "lucked out" :) 00:26
colomon right
sjn thanks, 00:29
sjn also now understands why [+]((11..*)[^14]) worked 00:30
sjn thought he was overriding presedence 00:32
TimToady well foo() is very high precedence :) 00:34
sjn r: say [+].WHAT 00:37
camelia rakudo-{parrot,jvm,moar} 28d672: OUTPUT«(Int)␤»
sjn r: say &[+].WHAT
camelia rakudo-{parrot,jvm,moar} 28d672: OUTPUT«(Sub+{<anon>}+{Precedence})␤»
TimToady verb vs noun
on top of which, &[+] isn't a reduction 00:38
timotimo it's interesting that it's sometimes easier to verb than to noun in perl6
TimToady both FP and OO are biased in favor of verbs over nouns, though differently
foo bar $baz vs $bas.bar.foo 00:39
timotimo i thought in OO you usually can't have a verb without a noun to accompany it? :)
TimToady .really?
timotimo well, in java.
timotimo remembers that article
TimToady but you often want to call methods on something that is returned
FP and OO just have different ways of cascading verbs
timotimo ah, mhm 00:40

masak "It's *possible* that one of the Perl 6 works-in-progress will reach a point of usability and gain stability and maturity as a useful product, with documentation, libraries, support, and uptake." -- that was the important one for me. 07:38
07:38 dayangkun left
masak first off, while there have been many parallel efforts during the years, right now basically all the focus is on Rakudo and its backends. 07:39
I understand if for a relative outsider that still looks like several works-in-progress. it doesn't feel like that from the inside.
DrEeevil hrm, it's not as bad as the python3 split, imo
masak no? interesting.
DrEeevil perl5 is not deprecated
python upstream actively tries to get people to use py3, with the usual response of "lol" - who is going to port all the code for us? 07:40
masak deprecation doesn't stop ~85% of the Python community from using Python 2.7
DrEeevil well, circular - e.g. django, it now has theoretical py3 support, but practically that's still not production-ready
so if I were starting any py project now, well, I still stick to py2
thus all my effort goes into improving py2 libs. derp :D 07:41
masak right. 07:43
DrEeevil so the business case for py3 is, hmm, I spend a few hundred to a few thousand hours of effort on no visible progress, and get a performance penalty for that
not something that interests me

ennio Hi all 09:23
09:23 synopsebot left
ennio I have a noob question 09:24
09:24 Timbus left
FROGGS hi ennio 09:24
09:24 synopsebot joined
ennio Is there any difference between declaring a string in code and reading a string from a file with slurp 09:25
FROGGS ennio: the string in the code is in a constant table, because it will always be constant in your program 09:26
the string from the file is not in that table of course
ennio I'm not able to read a markdown file and parse it with Text::Markdown 09:28
But it works with simple embedded strings
FROGGS so it seems that your are perhaps not reading the file in properly, or the file is misformatted 09:29
ennio: can you no-paste your code?
should look a bit like: say parse-markdown( "myfile".IO.slurp ).to_html 09:30
ennio gist.github.com/scriplit/7c9e86d0a8361dc41aa9
sergot ennio: I did this that way: github.com/sergot/filip.sergot.pl/...gen.p6#L90 09:31
but I didn't use slurp 09:33
FROGGS From embedded string:
<strong>bold</strong> and <em>italic</em>
From file:
<strong>bold</strong> and <em>italic</em>
ennio: it works on my box
ennio: do you get an error message?
ennio No such method ast for invocant of type Any 09:34
masak ennio: your gist certainly looks like it *should* work, both ways.
ennio: if someone manages to reproduce your problem, we might be looking at a bug report here... 09:35
sergot ennio: btw. Text::Markdown has only bold, italics and code working iirc
masak yeah, I should get on that :)
the target feature set is "enough so that I can run my blog on it"...
oh, FROGGS++ managed a non-reproduce above. I missed that. 09:36
FROGGS ennio: what is your perl6 --version?
ennio 2014.05 on MoarVM
09:37 [Sno]_ joined
FROGGS hmmmm 09:37
09:37 [Sno]_ left
masak odd. 09:37
FROGGS ennio: can you please also pass --ll-exception when running the script? and then no-paste the backtrace?
masak yes, that'll likely help a lot. 09:38
sergot ennio: work for me too
works
FROGGS I mean, this can only mean that it failed to parse the document...

sergot If we have no \n there it doesn't work with files containing empty lines, if we have \n+ there it deosn't work with just strings. 12:39
12:40 ivan`` joined
masak to be precise: I was fine with the addition of \n* -- I don't see why the + inside the [\n\n+] was removed. 12:41
that latter change seems unrelated to the PR, and so I don't want to accept it as it stands.
(and if the tests still pass with that + gone, then we're missing a test -- pull requests welcome) :) 12:42

masak <paragraph>* % [\n\n+] means "zero or more paragraphs, separated by two or more newline characters" 12:47
your change makes that instead "...separated by exactly two newline characters"
12:47 brrt joined
jnthn I mighta written taht as [\n ** 2..*] 12:49
ennio And more newlines are captured by \n* now 12:50
jnthn Yes, but the \n* after it doesn't fall within the paragraph separator, no?
If it's <paragraph>* % [\n\n+] \n* 12:51
masak what jnthn said.
ennio: you don't seem to understand the % construct yet.
ennio: <paragraph>* % [\n\n+] is one unit, tied together by the % 12:52
ennio: the thing that comes after the % in the [] is a separator
ennio Ok

PerlJam nwc10: you're in 4th place for what I assume is the p5 code (merlyn wasn't too clear about which code base he was using) Only about 60,000 more change lines and you'll be in 2nd! :) 13:27
13:31 atroxaper joined, kurahaupo joined
nwc10 unclear too. ohloh puts me second by whatever metric they use: www.ohloh.net/p/perl/contributors/summary 13:33
which might be number of commits. Not changes, not blame annotation
13:35 enza joined, ennio left
nwc10 typically, I think I've been making smaller commits than the mean commit size (but more of them) 13:35
and also I've removed more lines of code that many people
colomon removal++
13:36 carlin joined
nwc10 although don't confuse "lines of files shipped in the tarball" with "lines of code" - davem removed a lot of Changes files, and I've removed a lot of auto-generated stuff 13:36
PerlJam merlyn's metric using "git blame" won't give you credit for the lines that aren't there, but they are equally important (if not more important sometimes :)
nwc10 also, if I know what merlyn's metric is, I can game it, by systmatically removing or changing lines of code of the people "ahead"
jnthn :D 13:37
moritz assuming you actually care to game the metric :-) 13:38
nwc10 I'm more curious what the stats are for Rakudo, and how to dilute the scors of the current metrics: www.ohloh.net/p/rakudo/contributors/summary
scores of the current "winners"
ie, how to broaden the contributor base
13:39 enza left
jnthn lizmat++ is beating me in the last 12 months :) 13:39
nwc10 in particular, "Other" is slacking off. 17% all time, 15% last 12 months, and a mere 3% in the last month.
13:40 carlin left
PerlJam I think that Rakudo's code is easier to grok, so that barrier to entry is quite a bit lower than P5. It seems the "big" problem for contributing is finding useful problems to work on (or maybe finding problems to work on that aren't being quickly solved by the existing contributor base) 13:40
13:40 carlin joined
nwc10 PerlJam: OK, so how could we make it easier to match such tasks to potential volunteers? 13:41
moritz well, I had an approach 13:42
with weekly blog posts that invite people to solve very specific, approachable tasks
PerlJam I dunno. Maybe a big list of the known problems along with some hints as to what's need to solve them (knowledge of grammars, concurrent programming, etc.)
moritz and it got us a few short-term and medium term contributors
PerlJam moritz++ that's sounds awesome.
moritz but I ran out of steam and ideas 13:43
perlgeek.de/blog-en/perl-6/contribu...ounce.html # from 2010
PerlJam IMHO, our biggest lack is documentation, tutorials, and whatever other "educational" materials we can generate to get people started *using* P6. 13:46
That's what I intend to do if I can ever find some time and get my head oriented right--write some stuff that helps people get started 13:47

vendethiel (and probably the most profilic ones) 13:50
PerlJam moritz: re, running out of ideas ... Couldn't we troll the RT tickets for ideas? Or does the problem then become the time it takes to specify the problem enough so that someone can solve it? 13:51
moritz PerlJam: well, RT is full of stuff; sifting through it to find something that you are confident that is easy to fix is the problem. Plus writing up, yes 13:52
13:53 thou joined
PerlJam maybe at the next YAPC, instead of a hackathon, there should be a specifiathon where we troll RT and pull out problems for people to solve and specify them enough so that others can contrubute. 13:55
well ... by "we" I mean "you guys" because I won't be at YAPC this year :( 13:56
moritz PerlJam: well, the real problem is that this preparation needs to happen *before* the specifiathon
13:57 thou left
PerlJam aye. That makes sense. 13:58
moritz we can start crowd-sourcing problems/tickets now, and then either use it for YAPC or blog-driven 13:59
PerlJam The beauty of a whatever-athon is that its designated time. You know going in what you're going to be doing, so you prepare to do it. If you try to do the same thing "in your spare time", you never have enough spare time to make significant progress. (OR maybe that's just my personal problem)

fix precomp bug about colonpairs in 'use' statement

When we pass a colonpair to a use statement it can land in the compiled compilation unit before the CU's serialization context is created. Which means that we cannot have WVal there, since these need the SC of the CU to be deserialized. This patch cares about strings, i.e. in :from<NQP>.

japhb_ Saw the patches sometime in the last week that made $*USER and $*GROUP work. They are objects that .Numeric and .Str appropriately. Is the 'true dualvar' concept -- single values that ~~ Int and ~~ Str at the same time -- now dead? 17:57
jnthn IntStr may well end up being more dualvar-ish, but doing that for $*USER and $*GROUP feels odd to me. 17:58
japhb_ Does IntStr work in Rakudo now? (Did I just miss that happy moment? :-) 17:59
TimToady yeah, that's not really the intent of IntStr...
japhb_ Sigh, no joy from 'git grep'
jnthn NYI 18:00
japhb_ TimToady, I know the intent of IntStr was for e.g. command line args, but why *wouldn't* you use that for something like $*USER, assuming it worked?
jnthn japhb_: I think using IntStr for something that isn't two representations of the same peice of information (like "42" and 42) is probably a bit of a design smell. 18:01
japhb_ Ah, I see. That dividing line makes sense to me. 18:02

18:06 bluescreen10 joined
japhb_ But I understand jnthn's point of reserving dualvars for 1234 and '1234' 18:06

jnthn From the reliable source of answers that gave us "how is babby formed": answers.yahoo.com/question/index?q...709AA3MAO7 18:47
It's so not agreed upon :)
geekosaur you expected the US to be sane?
jnthn No, I expect to get an enum of names so I don't have to worry about this :P 18:48
18:48 bbkr left
nwc10 so if they are called "ugh", "meh", "bleurg", "wa :-(", "POETS!", "yay", "zzz" it doesn't matter to the program? 18:49
masak jnthn: also from that page: "ISO prescribes Monday as the first day of the week with ISO-8601." -- the rest of DateTime intentionally stays very close to ISO-8601. 18:50
nwc10: thank god it's ughday.
jnthn masak: I'm not arguing for a change to "what is the first day".
masak *nod*
nickpatch masak: the CLDR defines the first day of the week for different locales
jnthn masak: I'm arguing for not leaving people having to guess wrong, like I mighta :)
nickpatch www.unicode.org/reports/tr35/tr35-3...#Week_Data
masak jnthn: I don't have a horse in this particular race. if you can get popular support for introducing a WeekDay enum, go ahead. 18:51
jnthn OK :)
masak ...though I would prefer for the enum not to mess up the existing integer values, if nothing else for compatibility's sake... 18:52
(and because I did ponder it quite a lot, and I believe I got the "right" design choice)
jnthn Yes, I'm fine with the integer values. 18:54

masak an interesting case of the inverse of a once-and-only-once refactor being the right thing to do, due to surrounding forces. 20:07

vendethiel do we have anything that looks like (delimited) continuations ? 20:10
Or are we bound to do this sort of stuff through macros
20:10 eMBee joined 20:12 virtualsue joined 20:13 rgbkrk_ joined
timotimo gather/take is implemented in terms of delimited continuations 20:15
masak vendethiel: TimToady has said pretty definitively that (beyond gather/take), delimited continuations aren't going to be exposed in Perl 6 as first-class things. 20:16
timotimo oh
vendethiel mh; I see.
I can guess why, but meh :(
masak vendethiel: mainly because all VMs we'll want to target won't have them.
20:16 itz_ joined
vendethiel Good point, actually. 20:17
20:17 rgbkrk left
[Coke] DOH. I didn't update rakudo-jvm before trying this test. 20:18
vendethiel But it's a really, really powerful feature. I guess I still will be able to rewrite stuff in macros, someday

'in method message'... as if it explodes in a exception

camelia ( no output )
FROGGS ahh, yeah
jnthn Yes, it's exploding trying to report the exception.
FROGGS of course
jnthn++
jnthn But the reason for the exception is the bind failure
But in general we need to make other-language things appear to be any

ChoHag Does rakudo build on freebsd? 22:44
FROGGS I think so, yes
ChoHag Does it need anything special? 22:48
And/or are there dependencies documented anywhere?
FROGGS the dependencies depend on what you build 22:49
look at moarvm.org when you want to build rakudo@moar
you can also build rakudo for jvm, then you just need the jre and Perl 5 AFAIK 22:51
if you build for parrot, then libicu would be nice to have
BenGoldberg I just had a really crazy idea... perlito allows perl6 to be compiled to javascript; javascript and actionscript are supersets of ECMAScript; how hard would it be to modify perlito to produce ECMAScript which can *either* as javascript *or* as actionscript? 22:57
Running perl6 in a flash player could be really cool, I think 22:58

sadly, the subset of perl6 that perlito can do is quite limited 23:05
