geekosaur preps to nuke rakudobrew and start over again... 00:38
AlexDaniel weeeeelll for that you'd need rakudobrew to adapt
geekosaur hm, actually I suppose that won;;t work until rakudobrew itself is updated; it knows about nom

timotimo how hard can it be to write a blog engine … 00:51
Zoffix wrote the one that drives rakudo.party in an afternoon :P 00:52
timotimo heh. 00:53
what kind of features does it have? i take it it's a static site generator?
Zoffix No, dynamic. With a command to pull from repo and repo got markdown files: github.com/zoffixznet/perl6.party/...aster/post 00:54
errr. wait don't look there!
timotimo er, oops?
Zoffix hides all the unfinished drafts :)
bitrauser spoilers D:
timotimo but how does your command differentiate between draft and release? a field in the markdown perhaps? 00:55
Zoffix And this is basically all the code for it github.com/zoffixznet/perl6.party/...y/Posts.pm and github.com/zoffixznet/perl6.party/...ter/app.pl
timotimo: the posts have metadata at the top (the `%%` things): raw.githubusercontent.com/zoffixzn...-Update.md
drafts have `%% draft: true` in the metadata 00:56
timotimo neat
Zoffix On top of markdown, the features is just some shortcuts for IRC quotes, links to routine/class docs and and markdown massager to make posts suitable for copy-pasting to blogs.perl.org :)
timotimo it also has the glot.io snippet support right? 00:57
Zoffix Oh right yeah, that too
This: github.com/zoffixznet/perl6.party/...js#L14-L74
timotimo this test.p6 seems extremely useful
thanks for sharing that
Zoffix + code mirror for highlights; + this for backend to access glot.io API github.com/zoffixznet/perl6.party/...pl#L49-L67 00:58
:)
timotimo i should go to bed
have a good one! :)
Zoffix You too \o

Zoffix chars as bytes.. I'm not sure what you mean. 02:18
jdv79 i have a byte size limit but utf8 makes substringing less obvious 02:19

Xliff jdv79: So, force single character strings? 02:19
jdv79 no. just get the biggest substring i can fit
Xliff Er... Single BYTE encoded stringss
So single OR multi-byte characters that fit into a buffer of a specified size? 02:20
jdv79 yes
02:21 noganex_ left
jdv79 i just brute forced it by chopping in a loop until the byte size fites 02:22

patrickz Hey! Is there any documentation how to create modules that contain C code and thus need a compiler during install? 12:51
DrForr Not sure how much documentation there is, but I'd definitely check out Inline::Perl5, plus if you're distributing the library separately you can always use NativeCall for an interface. 12:54
12:55 synopsebot joined, ChanServ sets mode: +v synopsebot
patrickz I already looked at Inline::Perl5, but that module looks a bit overkill using a Configure.pl and Makefile.in. 12:55
12:56 synopsebot left
patrickz The library is just a tiny little bit of supporting C code that is more easily done in C than perl6. 12:57

Does anyone know if DBIish is thread safe (in practice)?
moritz back when I wrote some code in it: no 14:37
most of the underlying DB libraries assume that you use the DB handle on the same thread where you opened it
piojo_ moritz: I'm doing that, but something's going wrong anyway 14:38
14:39 Coleoid joined
piojo_ I posted about it on stackoverflow, because I can't exactly post a good test case here. (But maybe I should post somewhere else, because it's not syntax highlighted on SO.) stackoverflow.com/questions/tagged/perl6 14:41

14:47 Piotr_ joined
AlexDaniel do I get it right that “latest” on travis is HEAD? 14:50
piojo_ Yeah, recently there's been one guy posting almost every day. It's cool. Fun to see questions waiting. :)
AlexDaniel or is it the latest release?
piojo_ Haha, did everybody just go to stackoverflow and upvote the recent questions and answers? 14:53

DrForr Not I, I hardly use my account. THough again that should change. 14:55

piojo_ moritz: Thanks a lot! I'll test it, though if I might have to wait until Monday if I can't reproduce on my home computer 15:03
I'll let you know if that was it
but that really looks like the problem! I forgot %h«» interpolates but %h<> doesn't 15:04
moritz but don't use %h«...» there 15:05
piojo_ I need to break the habit of using %h<> so often
moritz it splits the key on whitespace
piojo_ Oh yeah, I know it woud be wrong
but it would also work.
(in this case)
moritz no
because it interpolates $*THREAD but not .id
piojo_ oh, indeed. haha. Then it would have to be $*THREAD.id() 15:06
but like I said, I really need to break that habit.
moritz right
AlexDaniel answering my own question: “latest” = HEAD on the default branch 15:11

ugexe github.com/CurtTilmes/perl6-dbi-async - this uses DBIish and uses threads to do connection pooling 15:25
15:26 lostinfog joined
ugexe and keying on $*THREAD.id doesn't mean you are keying on an id that will always point at the same thread 15:27
key on just $*THREAD I believe
jdv79 is it true that a "non-capturing group" aka [] can be made capturing by naming it? 15:28
moritz jdv79: you can do something like $<foo>=[...]
jdv79 seems to work but the docs seem conflicted about that
moritz m: 'abc' ~~ /$<newname>=[.]/ 15:29
camelia ( no output )
moritz m: say 'abc' ~~ /$<newname>=[.]/
camelia ｢a｣
newname => ｢a｣
moritz m: say 'abc' ~~ /$<newname>=./
camelia ｢a｣
newname => ｢a｣
jdv79 yeah, weird. the docs call [] non-capturing:)
moritz well
it doesn't capture, it groups
it's just that $<...>= captures the next atom
jdv79 its a named capture, isn't it?
moritz whatever it is
jdv79 haha
15:30 HoboWithAShotgun joined
jdv79 that's gonna confuse people but ok 15:30
15:30 wamba left
moritz so here, with [] you just define what's part of an atom 15:30
nobody said regexes were easy...
jdv79 i guess its just the docs for me. creating a named capture using non-capturing grouping 15:31

jdv79 not sure how to reword that correctly though. i'll bug it i guess. 15:31

 15:37
moritz jdv79: IMHO it's better to think of [] as just a "group" 15:38
and () as a "capturing group"
and $<...>=... is a modifier that makes anything after it capture
15:38 kyan joined
jdv79 hmm, how come i can't do $0.?Str 15:48
in other words is there a way to tersely convert a match to a string if it matched and Bool false if it didn't 15:49
moritz $0 && $0.Str
jdv79 kinda like my $var = $<var>.?Str // $default-var if it worked 15:50
i thought maybe there was something shorter
piojo_ Oh, I'm interested in that, too
jdv79 its good. tanks.
15:51 wamba joined
piojo_ I found myself setting: my %data = from-json (%data<field> // "{}"); 15:51

piojo_ Err, didn't mean to use the same variable twice. Should be my %result = from-json (%data<field> // "{}"); 15:53
perlpilot what was ugly about it?
moritz needs to be '{}'
jdv79 yeah, i think {} interplates away
15:54 rindolf left
moritz %result = $_ ?? from-json $_ !! {} given %data<field>; 15:54
perlpilot I'd call that one more ugly
piojo_ it makes more sense, though. 15:55
ugexe it would break on invalid json such as bare 0, no? 15:56
15:56 Cabanossi left
piojo_ ugexe: in my case it's coming from a database (a JSONB field), so it must be a string 15:56
but yeah, if needed we could change it to $_.defined 15:57

AlexDaniel stmuk++ 16:01
stmuk I haven't tried it on Windows yet TBH. That might be "interesting" :)
piojo_ oh, haha
I was wondering why it was .tar.gz
and I forgot star was for linux, too 16:02
because it doesn't work on archlinux, I started thinking it was just a windows thing.
I mean, I mean there's no package for archlinux
stmuk its a source tarball
piojo_ I'm sure the download works fine.
yeah, we package our source installs
but that's not working for rakudo star.
ugexe m: my %result; %result<foo> = Any; my $x = %result<foo>.?Str // 42; # an annoying problem with `.?Str // ...` 16:03
camelia Use of uninitialized value %result of type Any in string context.
Methods .^name, .perl, .gist, or .say can be used to stringify it to something meaningful.
in block <unit> at <tmp> line 1
piojo_ It's one of the snobbish distros that has complex wrapper scripts for most source builds
AlexDaniel star: say 42
camelia 42
AlexDaniel what should be done to update this ↑ ?
moritz currently, I still do that manually 16:04
piojo_ moritz: you definitely solved the DBIish issue. Thanks! I'll add a note to the relevant code so no other noob can read over it and accidentally think the technique is correct.
moritz if somebody wants to automate it, even better

number8 hello, everyone! i'm trying to store all regex captures in a single line doing something like $string ~~ m:g/ (pattern)? / ... but how can i store all captures in an array? 17:30
timotimo you can use comb instead, if you pass :match inside it'll give you the match objects corresponding to every match rather than just the matched string 17:32
17:32 scovit left
timotimo m: my @results = "hello how are you today?".comb(/ \w(\w+)\w /, :match); .[0].say for @results 17:33

number8 timotimo: awesome, thank you. i have to read the comb documentation because i thought it only returned a list of the individual elements of a sequence... 17:35
17:36 epony left
timotimo you can also use $string.match(/ (pattern)? /, :g) for the same purpose 17:36
and i think if you my @results = $strign ~~ m:g/ (pattern)? / it'll also give you what you want 17:37
[Coke] AlexDaniel: "nom regression" indicates that it regressed when we cut over to nom from the previous master. so yes, don't rename those. 17:39
number8 i tried that last one but it stored the ｢capture｣ in that format, whereas i'm only interested in the capture as a string

knight__ When I have hash, and hash has some key and value is array and array contains a hash. If I do %hash<key> that returns array of hashes not one hash 18:58
for example

Why it does not return a whole hash in array?
I do not understand it.

El_Che I created a Ubuntu 14.04 pkg for using it with travis on my own projects. The rakudobrew community version is too slow for long jobs.

AlexDaniel HoboWithAShotgun: what about this? ↑
HoboWithAShotgun i think it's because a hash is just a list of pairs so {a=>3, b=>4} is actually [:a(3), :b(4)] and that [[:a(3), :b(4)]] gets then flattened somehow? 19:14

HoboWithAShotgun i don't care about the rationale, that's wrong. 19:35
ugexe what if the solution was wrong somewhere else? 19:36
raschipi The one argument rule is by definition correct
19:36 troys is now known as troys_
number8 moritz: for example, i want to read a file line by line: for $filename.IO.lines -> $current_line { ... 19:36
moritz number8: we could help you much better if you provided an actual, concrete example
AlexDaniel no he is actually right, it's really weird
for example
m: say ((50))
camelia 50
AlexDaniel m: say [[50]]
camelia [50]
moritz it is weird, yes
but we haven't found a better solution
HoboWithAShotgun it makes every notation of a datastructure erratic 19:37
lizmat HoboWithAShotgun: no, the rule is consistent
ugexe thats a bold claim
lizmat anything iterable used as a single value / parameter, will be iterated over / flattened
HoboWithAShotgun sure you can have an array of arrays, but all arrays must have at least two elements...
raschipi m: my @a := [[1]]; say @a.perl;
camelia [1]
moritz HoboWithAShotgun: or you just use a trailing comma 19:38
AlexDaniel HoboWithAShotgun: oh, you're misunderstanding it! [42,] is not two elements
number8 then for each line i want to find ALL instances of / .* (THIS) .*/
moritz m: say [[1,],].perl
camelia [[1],]
AlexDaniel number8: / .* <( THIS )> .* /
raschipi m: my \a := [[1]]; say a.perl;
camelia [1]
moritz number8: just leave out the .* on both ends
AlexDaniel or that ↑
ugexe .lines.map: { if $_ ~~ / ... / { say $0 } }) 19:39
AlexDaniel depending on what your actual example is

ugexe moritz: but if he wants the value its easier to grep at the end for .defined than to do another map to get the actual value 19:40

HoboWithAShotgun actually i think i mixed that up with cargo-culting, what did slashdotting then mean again 20:22
timotimo getting featured on slashdot and your web server going down under the enormous traffic, that's slashdotting to me 20:23
20:30 as_ joined
geekosaur your web site/blog/whatever went viral and everyone's trying to load it at once 20:31
also I have decided I don't like the way programmers sneer about 'cargi culting' 20:32
like it or not, that's how the human brain works
mspo IT is heavily fashion driven 20:33
that is reality
marketing of technologies is weird but can pay off big time if you manage to start a trend 20:34
HoboWithAShotgun oh, i'm all for copying the closest existing piece of code and massage it into your needs, saves a lot of time sometimes
but: you must understand it. 20:35
geekosaur that's not the problem. the problem is the attitude we bring to it
mspo oh I was thinking of something else :) 20:36
20:37 bdmatatu left
perlpilot geekosaur: you think cargo culting is a pragmatic solution that we shouldn't look down upon? 20:37
geekosaur sigh
what did I just say
perlpilot I dunno, that's why I'm asking for clarification. 20:38
geekosaur you may well be part of the problem then.
'cargo culting' is our natural way of understanding the world around us.
guiding people to actually understand things is good,
Being snotty about it is NOT. 20:39
perlpilot gotcha.
geekosaur and even the label is a severe put-down
lowin How do I read environment variables?
as_ %*ENV?
geekosaur m: say %*ENV<HOME>
camelia /home/camelia
perlpilot lowin: they're in %*ENV
lowin perlpilot, I tried %*env<REMOTE_ADDR> 20:40
throws an error
as_ lowercased
perlpilot lowin: "ENV" and "env" are not the same thing
lowin oh my bad
as_ hi, i have something about the new atomic operations
why we neeed the utf character at all?
timotimo you don't need the character 20:41
20:41 Cabanossi left
as_ if the variable has to be declared as 'atomicint' anyway 20:41
timotimo: what do you mean? ascii versions?
perlpilot as_: call it another hint.
as_ but it is hard to type
geekosaur as_, because you can operate on it normally as well if you don;t need the atomicity
but to be atonic it *needs* to be stored a particular way 20:42
*atomic
as_ i think if i need an atomic variable i would want perl to think about it, not me
geekosaur as well as the atomic op itself being special
as_ like "atomicint" forces all operations to be atomic
perlpilot as_: in this case *you* do need to think about it :)
20:42 Cabanossi joined
as_ that can be an acceptable tradeoff 20:42
geekosaur as_, but that is impossible
most things perl 6 does cannot be atomic
as_ no. if i say "atomic" - what things cannot be atomic? 20:43
geekosaur they can be done under an atomic lock but they cannot themselves *be* atomic
jnthn as_: The ops are exposing low-level, hardware-provided, atomic operations. 20:44
as_ my atomicint $a; $a<ATOM>++ vs. my $i; $i++
timotimo you can't atomically divide, for example
geekosaur the only things that can be atomic are specific CPU operations with their specific restrictions
perl 6 can expose this to some extent, but because it;s the hardware/CPU that controls it it will always be limited in any higher level language
as_ thread support is now very simple 20:45
jnthn lol
perlpilot as_: along one axis maybe
as_ but atomic operations are a bit more difficult syntactically
geekosaur so you think that can automatically be done for anything else?
jnthn Anyone who puts "thread" and "simple" in the same sentences hasn't done enough with threads ;-)
20:46 ifim joined
as_ jnth: for the user, not for you :) 20:46
geekosaur as_, perl 6 cannot rewire your CPU.
*the CPU controls this*.
jnthn as_: There are function version if you don't want to type the atom :)
*versions
geekosaur languages do not. Operating systems do not.Programmers do not.
lowin Another stupid question. How can I get the size of an string in bytes?
perlpilot lowin: bytes or chars?
lowin bytes
as_ jnthn: i mean i don't want to type <ATOM> or its ASCII replacement as soon as i claimed the variable is an atomicint 20:47
perlpilot lowin: then you don't want a string
lowin What do I want then
geekosaur buf8
El_Che perl5 autodie is a new requirement of moar I see
[Coke] lizmat: I should go see Thor next week, yes? 20:48
jnthn lowin: A string can be represented in many different ways, (latin-1, utf8, utf16, etc.) and the number of bytes will differ.
20:48 bdmatatu joined
lizmat [Coke]: yeah, it's fun (mostly) 20:48
jnthn lowin: So you'd want to do $str.encode('utf-8').bytes for example
lowin jnthn, appreciate it. thanks
geekosaur lowin, despite what other languages may have mistaught you, a string is not a string. A string has a specific encoding and a specific representation (in perl 6, graphemes). it could also be Unicode codepoints, ISO8859 characters, etc. 20:49
lizmat [Coke]: definitely a more Guardians of the Galaxy feel than the previous Thor movies
jnthn as_: We can't do that, because native types don't actually knwo what kind of thing they are
[Coke] lizmat: cool. I've been super jazzed for it since the first trailer. :)
lizmat (and that includes using the Immigrant Song prominently in the movie)
as_ jnthn: ah - that explains (a bit)
jnthn as_: So we can't multi-dispatch on int vs atomicint for example
But also, from a language design perspective, we give different semantics different operators. 20:50
as_ jnthn: does it mean i can use simple 'int' and use atomic operations with it?
jnthn Thus + for numeric addition and ~ for string concat
[Coke] gives up on $dayjob and goes on strike for 2 days!
geekosaur I am somewhat tempted to argue that atomicint should be a internal thing not part of perl 6 as such.
lizmat [Coke]: www.youtube.com/watch?v=8QxtIQ1F1ig # but you've probably already seen that
jnthn as_: You can...sort of. But atomic operations are restricted to the sizes the CPU can do them on
geekosaur [perl 6 might make visible synchronization/locking stuff at a higher level, whose implementation uses atomicint under the hood 20:51
jnthn as_: atomicint is simply an alias to whichever size is doing to work
uh, is *going* to work
lowin geekosaur, I come with C background. If you have asked me last week, I'd tell you "there is no such thing as a 'string', just an array of bytes packed together"
as_ cheers:)
jnthn So you can write portable code
geekosaur but you will get stuff like this where as_ thinks atomicint is a high level operation that can be treated in high level ways, when fandamrnally a raw CPU operation and you MUST do exactly and only what the CPU will permit
perlpilot Even with all the new Perl 6 books, it seems we need a few more
geekosaur *fundamentally it is a 20:52
20:52 cdg joined
[Coke] lizmat: heh. Nice, I hadn't seen that cut with just the song. 20:52
jnthn geekosaur: Well, it's a "make the hard things possible" kidna thing. I'd like it to be possible to implement lock-free data structures in Perl 6. 20:53
20:53 darkmorph joined
geekosaur yes. but that should be implementation layer not public layer 20:53
because you cant make atomicint a proper Perl 6 type without breaking the CPU invariants 20:54
jnthn At the end of the day, though, we'd want to provide some standard way to access this functionality (that folks can use it their modules), and that'd mean it gets documented, and I'm not sure that sticking "this is implementation layer" and "this is public layer" in the docs will make a great deal of difference. 20:56

lizmat El_Che: autodie needed for Moar ??? 20:58
jnthn ah, gotta go away for a bit...bbl
timotimo lizmat: Configure.pl, if anything
or the exprjit compiler
El_Che lizmat: buildtime
20:58 cdg joined
El_Che it's new, I add to add it to the docker container 20:58
lizmat why would one need that as a prereq? feels like unnecessary laziness to me
(from the person doing work on Configure.pl) 20:59
El_Che other distros had it already in the installed perl pkgs, centos splitted that
so it needed to be added
lizmat ah, so it's not a recent change in Configure.pl causing this ?
El_Che it is
between 2017.09 en 10
lizmat: travis-ci.org/nxadm/rakudo-pkg/job...46517#L869 21:00
(ignore the exit 0 result, and explicit exit 1 was missing on that build)à
lizmat if I look at Configure.pl, I don't see a mention of autodie in there? 21:01
timotimo probably under lib/ 21:02
21:02 troys_ is now known as troys
El_Che The same succesful build is here, for reference: travis-ci.org/nxadm/rakudo-pkg/jobs/293870092 21:02
lizmat tools/expr-template-compiler.pl
tools/jit-dump.pl
but those aren't needed for building ??
timotimo i think the template compiler only has to run for developers? 21:03
or do we not have the results from that ni our source tarballs?
El_Che I don't do any magic in the build
21:03 darkmorph left
El_Che and autodie was not used in 2017.09 21:03
"cd /MoarVM*; perl Configure.pl --prefix=$PREFIX" 21:04
that's it
timotimo we don't check it into git i don't think
i *think* we could, but brrt will know for sue 21:05
sure*
lizmat the only two occurrences of autodie in the MoarVM tree are in those two files
El_Che These are the config parameters of that build: travis-ci.org/nxadm/rakudo-pkg/job...46517#L670
lizmat changed in 2017-05-15 and 2017-07-18
ah, but they got merged between 2017.09 and 2017.10 perhaps ? 21:06
I would be in favour of removing the autodie dependency 21:07

El_Che lizmat: did you say "remove the perl 5 dependency"? :P 21:09
lizmat no, autodie

my testcase is simple: ok !(12V == 12A) 23:49
