diakopter lue: are you sure you had libicu installed? 01:18
lue jsonrpc fails too. It's thanks to a "missing or wrong version of dependency" of MIME/Base64/PIR.pm6. Not sure why.

So, no-one yet can point me in a direction to this failure? :/ 03:06
oh, huh. Looks like `make install` fails on precompiling the offending modules. I just didn't catch that earlier it seems. 03:10
(LWP::Simple has the same "missing or wrong version" error as the tests, while JSON::RPC needs LWP precompiled to work.) 03:11
TimToady timotimo: in the normal Perl 6 RC page, the link to the unimplemented tasks is on the right in the Your Help Needed box 03:14
[Coke] lue: did make test work for the updated lwp-simple in teh R* release?
I mentioned that a few days ago in here, see you tripped over it too. 03:15

yeah, seems to be latest 03:17
[Coke]: I'll remember to check the R* runs before complaining next time, so I at least know more when I do :) 03:19
do you recall how you fixed it? 03:20
[Coke] I never fixed anything. I just reported the failure... and I see it's gone in today's daily run 03:21

had at least 2 days where it was working.
(including today) 03:22
lue *headdesk* I just _knew_ this was why updating the MIME::Base64 module was troublesome earlier. I just _knew_ this error was the reason behind that. And now I have proof :)
irclog.perlgeek.de/perl6/2013-11-23#i_7905580 <-- evidence, for the curious
[Coke] (when I asked if you fixed it, I didn't realize my daily run had cleared up.) 03:23
lue
.oO(the insidious part of the error is that it's the things *using* ::Base64, not the module itself, that fail. Which would make git blame and related strategies a bit more involved.)
 03:24
...I'm gonna need to make 2013.12.1 tag for R*, aren't I? :)
oh, nvm, tagging doesn't happen yet. phew. 03:28
[Coke] you only need to make a .1 tag if you made a non .1 tag already 03:31

Update release guide to deal with Perl6::MIME::Base64

There's no easy way to modify the existing submodule command to skip Perl6::MIME::Base64, in a cross-platform way. So instead presented here is a way to fix Perl6::MIME::Base64 getting a merge commit.
The sooner we don't need this addition to the Release Guide, the better.

timotimo is your nickname raydiak because you do raytracing?
moritz raydiak: if you release the code tomorrow, you can post the announcement as day 25 of the advent calendar :-)
raydiak timotimo: sorta, but it's more based on my real name..."Ray" is literally my middle name :) 16:05
diakopter diak is your last name?
raydiak moritz: I thought all the days were gone now...???...
diakopter opter is timotimo's middle name
moritz raydiak: well, advent calendars typically only go to 24, which is why only the days upto 24 are taken 16:06
raydiak: but there wouldn't be any harm in adding another day :-)
raydiak diakopter: ha ha :) it's too early for me to come up with anything clever to answer that with
moritz: oh right...well, that's a thought; I do have half a day of peace to myself 16:07

timotimo and you expect the [^3] to flatten the LoL before accessing? 18:03
kind of makes sense; it already says .list at the end
and the .list of that should be flat
raydiak timotimo: I'll be sure to let you know if I notice anything obvious when I start profiling (if japhb doesn't beat me to it...he mentioned a "barely contained obsession with optimizing 3D graphics code") 18:04

Ulti if I wish to map a list to triplets from that list what is a perl6ism for this that returns the new list using something like for @list -> $a,$b,$c {} works but is there something like map that consumes more thna one value? 19:14
timotimo isn't for the same as map, basically? :P 19:15
i'm confused; why isn't eqat available in the stage0s? we recently rebuilt the stage0s :( 19:17
Ulti I dunno I just tried map {"$^a$^b$^c"}, @list and it didn't work out 19:18
timotimo i just mean: why not use that exact for?
Ulti because its a bit unwieldy 19:19
timotimo well, use the for just to make triplets then?

timotimo to completely confuse anyone ever :) 20:05
Ulti the [X] (@list xx 3) is a no go though since its not three lists but one list made from three appended by the looks of it
timotimo also i think your Str @!bases would look better with < ... > syntax as well
Ulti timotimo yeah I realise I could make some epic single line :) 20:06
timotimo no, i think that really would look nicer :)
Ulti I meant more the Z=> sorry
timotimo oh? no, i just needed a hash to test if <<>> will interoplate and turn into postcircumfix:<{ }> 20:07
and i thought Z=> was the shortest way
Ulti ohhh
timotimo in the same vein, i could have written Z=> 1..*, or even used <a b c d e f g>.kv
hm. i wonder if there's a reason to have .vk and .sriap, too 20:08

Ulti really it would be nice to get rid of the {} to have something as expressive as the previous map *~*~*
timotimo grondilu also suggested the [X~] $@!bases xx 3 20:13
Ulti timotimo yup one second
timotimo that's wicked concise
the $ prefix to turn the list into being item context is pretty slick
i should remember todo that more often
Ulti done 20:14
ahh so that gets you a reference to the list and then 3 of those
yeah thats nice though the plan wasnt to golf lol
I like it though
timotimo "reference to" isn't a good way to say it, IMO 20:15
oh hey
your join, map, comb looks just like a .trans 20:16
Ulti hmmm $@!bases throws up too 20:17
"Unsupported use of $@ variable as eval error; in Perl 6 please use $!" 20:18
timotimo whoops, that's a bug.
timotimo has a look at the grammar
Ulti $(@!bases) does work 20:19
20:19 grondilu joined
Ulti which I got via the usefule message: Unsupported use of ${@!bases}; in Perl 6 please use $(@!bases) 20:19
timotimo m) 20:20
Ulti so in Perl5 that would be scalar context... scalar context means the object representing a list type?
grondilu weird. $@ works fine here (rakudo star november)
Ulti This is perl6 version 2013.09 built on parrot 5.5.0 revision 0 20:21
grondilu r: my @a = rand xx 2; say $@a
camelia rakudo-parrot d72797: OUTPUT«0.249971135842742 0.298091508719278␤»
..rakudo-jvm d72797: OUTPUT«0.1677135985885968 0.2767544824499587␤»
timotimo interestingly the rule to find $@ looks for \W, '(' or a sigil
wow, ulti, that's old!
Ulti grondilu: might be the class variableness
timotimo: heh yeah :P
I am on my work laptop rather than my personal one (xmas)
timotimo it b0rks on my local version, too 20:22
Ulti so what is $(@list) doing?
because it feels different from what you might imagine from Perl5
timotimo it's the same as @list.item 20:23
afterwards, @list will not interpolate
r: say (1, 2, (3, 4, 5), 6, 7).list.perl; say (1, 2, $(3, 4, 5), 6, 7).list.perl
camelia rakudo-parrot d72797, rakudo-jvm d72797: OUTPUT«(1, 2, (3, 4, 5), 6, 7).list␤(1, 2, $(3, 4, 5), 6, 7).list␤»
grondilu also, you can do: return %codon_table{map *~*~*, $!seq.uc.comb}.join
timotimo oh, excuse me, .perl will still give you its structure
r: .say for (1, 2, (3, 4, 5), 6, 7).list; .say for (1, 2, $(3, 4, 5), 6, 7).list 20:24
camelia rakudo-parrot d72797, rakudo-jvm d72797: OUTPUT«1␤2␤3␤4␤5␤6␤7␤1␤2␤3 4 5␤6␤7␤»
timotimo you see how there's no newlines between the second 3, 4, 5?
that's the effect $... and ....item have on lists 20:25
Ulti okedoke but what $($string)
is it just meaningless
timotimo no change, $string is already in item context, because it is in a $-sigiled variable
grondilu r: my $x = rand; say $$$$$$$$$$$$x 20:26
camelia rakudo-jvm d72797: OUTPUT«0.4587225161057409␤»
..rakudo-parrot d72797: OUTPUT«0.276195594432892␤»
grondilu ;-)
timotimo that's also why we have \ sigil-less variables; these don't have an item/list context or anything like that
grondilu: oh shit! it behaves differently on our two backends!
time to throw one away!
Ulti hmmm so scalars feel refrency
timotimo i have no past with perl5 or earlier.
no history* 20:27
Ulti so is something like $list = (1,2,3) a list thats always in item context?
grondilu should remember to avoid using rand for value examples when calling r:
timotimo yeah
grondilu r: my $a = (1, 2, 3); .say for $a, 4, 5, 6 20:28
camelia rakudo-parrot d72797, rakudo-jvm d72797: OUTPUT«1 2 3␤4␤5␤6␤»
grondilu r: my $a = (1, 2, 3); .say for @$a, 4, 5, 6
camelia rakudo-parrot d72797, rakudo-jvm d72797: OUTPUT«1␤2␤3␤4␤5␤6␤»
timotimo anyone else think the evalbot should write ␤ instead of just ␤?

Ulti yeah I looked in Cool too 20:34
its in Str in the core shizzle in Rakudo
timotimo it's mentioned there, but there's nothing about it here
Ulti reading the source rather than the docs
timotimo mhm, yeah
it's in the synopses in any case. 20:35
Ulti I think maybe the docs.perl6.org hasn't been rebuilt in a while 20:36
or is it not coming from the source code?
also I cant believe I forgot about [X~] considering I used it to make some decks of cards only a few months ago 20:37
timotimo i do think it comes from the source code
20:38 jnap left
timotimo er, doesn't it come from the docs/ folder? 20:38
Ulti yeah I doubt its the actual source because there aren't any pod comments
or comments...
retupmoc1 re: MIME::Base64 and R* - the problem is that precompilation breaks somehow on the conditional require 20:39
timotimo that's right
the core setting is already painfully slow to compile
retupmoc1 without precompilation, everything works correctly
timotimo if we also parsed Pod6 inside it ... ouch
20:39 retupmoc1 is now known as retupmoca, SoemGyu joined
timotimo i know for a fact that there's still lots to be optimized in the pod6 parsing we do. 20:40
Ulti timotimo use a perl5 script to strip it all and mangle variable names to be short like JS "compilers"
timotimo well, to be honest ... i tried to optimize it and didn't get any wins
they are actually called "uglifiers", at least i heard that name used often enough.
lue retupmoc1: yeah, I read the commit on the precompile-fix branch :)
Ulti heh

timotimo looks at STD before changing rakudo
do you want to open a rakudobug so i can tag the test for it? 21:04
Ulti thought it would be easy to make a DNA or RNA sequence subclass where just the @!bases list was different :S
timotimo can do if you step me through opening one which I imagine starts with me getting an account to submit a ticket
timotimo @! is private
Ulti what so a subclass can't define it? 21:05
timotimo if you want to override the way @!bases behaves from a subclass, you have to go through an accessor that gets overrided
you can't define it?
Ulti yeah but the methods from the super class use the undefined one
timotimo you should just be unable to access the superclass' one, no?
from the subclass, that is 21:06
Ulti I also tried making it @. but it didnt change anything
timotimo it should; but you have to access them with @. as well
Ulti its more the methods are in the super class and I wanted the sublcasses to just define a different parameter
timotimo if you access them with @!, you'll end up accessing the private one of either the subclass or the superclass
Ulti yeah no thats what I did... I'll keep playing
timotimo can you update the gist so i have something concrete to look at?
Ulti oh I must have missed one before 21:07
just tried again ;]
its working now

Ulti the problem I have is that once I have my own constructor the magic that overrides goes all to hell because in BUILD I do a bind to $!something rather than $.something 21:49

timotimo i don't understand why your BioInfo::Sequence just invariably dies 21:55
diakopter Death does what Death wants
timotimo Ulti: i think you want something like method residues { <T C A G> } instead of a member 21:57
alternatively, your DNA/RNA sequences could do a role Sequence[Str @residues] 21:58
Ulti timotimo: testing is why it invariably dies 21:59
timotimo anyway, i think you want something different from a member variable 22:04
it's a property of the class rather than of any one instance
so either do the method or the role?

timotimo Ulti: do i understand correctly that you want the sequence to be checked for wrong characters? like an X for example? 22:11
Ulti timotimo not sure I do want the role because some sequences wont be DNA ;) 22:12
or RNA and use residues which have a tonne of different operations on
timotimo hmm.
Ulti but the concept of a constrained alphabet common to them all is still true
timotimo in that case i'd go for a RestrictedToAlphabet role that has a @.alphabet or a method like that 22:13
now i'm thinking about what the smartest way to reject strings that have invalid characters in them is.
iirc, if you interpolate an array into a regex, it'll work like an LTM alteration
let me check that
r: my @alts = <foo bar baz>; "bar bar baz" ~~ m:s/ <@alts> +/ 22:14
camelia ( no output )
timotimo r: my @alts = <foo bar baz>; say "bar bar baz" ~~ m:s/ <@alts> +/
camelia rakudo-parrot d72797, rakudo-jvm d72797: OUTPUT«｢bar bar baz｣␤␤»
timotimo cool.
so you can just match for ^ <@.alphabet> $
Ulti yeah I already knew you can expand that list to be a character class I did it previously in a little grammar that parsed these sequences working out if it was DNA or RNA 22:16
well guessing
timotimo :)
for that i would have bag $foo.comb, tbh 22:17
Ulti well this was a grammar that parsed some of the file formats and it just had some rules that let it choose between the three depending on what matched 22:19
timotimo oh
well, in that case ... :)
Ulti so I'm trying to make some classes to build actual objects that are useful from the sequences parsed :) 22:20
lue preflex: tell moritz the only file to differ between the two tarballs is <tarball>/MANIFEST, and *I think* it's just that the sorting of files in them is different. I also don't spot any files that only appear in one tarball. 22:25
