IOninja is it somehow possible to add a sub that would be visible everywhere? 00:58
Like, I'd alias `perl6` to `perl6 -MM` and it'd always load my module with the above sub and it'd just be available everywhere in the code?

todd Hi All, I have been looking at perl6maven.com/introduction-to-perl...ast-arrays 02:40
IOninja \o 02:41
todd seems to me that I am quoting the guy. What is wrong with
IOninja Are you Todd?
todd Yes, I am Todd. Also known as "His Resplendances", but yo can call me "T" for short. 02:42
perl6 -e 'my @x = ('abc', 'def'); say @x;'
===SORRY!=== Error while compiling -e Undeclared routines: abc used at line 1. Did you mean 'abs'? def used at line 1
IOninja todd: shell quoting
todd which means?
Oh I get it 02:43
timotimo you're sending my @x = (abc, def); say @x; to perl6 as code
because ' belongs to the shell
02:43 risou is now known as risou_awy
IOninja perl6 -e 'my @x = (‘abc’, ‘def’); say @x;' 02:43
todd perl6 -e "my @x = ('abc', 'def'); say @x;"

todd Cannot call 'push' on an immutable 'List' 02:45
IOninja mhm
todd push ( @Report, "Completed with $ErrorCount errors\n" ); 02:46
IOninja todd: toss the parentheses or the space between push and (
Right now you're calling push(List)
todd I get away with thiw on Perl 5, but not perl 6. I could fid anything on perl6.org
IOninja Perl 5's a different language.
Death to parentheses! 02:47
todd I way to add the string as a new cell at the end of the array. What am I doing wrong?

IOninja With the code above?
02:47 ilbot3 joined, ChanServ sets mode: +v ilbot3
IOninja remove parentheses 02:48
todd ah poop. Did it again. "push(" fixed it. Thank you!

IOninja with... ?
todd for @Report -> my $Line { $StringFullOfLineFeeds .= ( "$Line" ~ "\n" ); }
Invalid typename 'my' in parameter declaration.
IOninja todd: don't use `my`
and those parentheses aren't needed
Death to parentheses! 02:55

this works too: for @Report { $StringFullOfLineFeeds .= "$^Line\n"; }

todd Interesting!
Net::SMTP anyone know the syntax to pass multiple eMail address in "To"? 03:04
comma seperated did not work
IOninja Based on the docs, I'd say pass them as a Positional 03:05
[email@hidden.address] [email@hidden.address]
['foo@bar.com', [email@hidden.address]
etc
todd a space and no comma? 03:06
IOninja Correct.
That's like qw/foo@bar.com [email@hidden.address] in Perl 5 (except I think it'd whine about '@' won't it?)
todd Bad to address: The following address failed to send: 03:07
IOninja Ah, no works.
hobbs no, qw is non-interpolating :)
IOninja It's the '#' it complains about :P
m: sub ($to) { for $to.list { .say } }( [email@hidden.address] [email@hidden.address] )
camelia foo@bar.com
meow@meow.com
IOninja todd: reading its code and it should work... 03:08
Does it work when you use the addresses one at a time?
todd that worked. Wow. That was obscure! 03:09
IOninja huh?
What worked? Sending one at a time? Well, it should work sending several at the same time with [email@hidden.address] [email@hidden.address]
todd address1\naddress2 03:10
worked
IOninja :S
todd placing "\n" between the addresses as a delimiter
IOninja By [email@hidden.address] [email@hidden.address] I meant literally, not a string 03:11
todd and they are showing up in my eMail too
IOninja m: dd [email@hidden.address] [email@hidden.address]
camelia ("foo\@bar.com", "meow\@meow.com")
IOninja ^ it makes a two-item list of strings
todd thank you! Got to go! 03:12

yeah i'd say 32 is fine. since things were revised in the GLR 09:20
it should probably go in 32

Quoted method name requires parenthesized arguments. If you meant to concatenate two strings, use '~'.

RabidGravy well apart from the syntax error, the idiom sets the $res to the result of calling the method named in $_ on it 11:47
sena_kun ZzZombo, I'm not sure, but... Perhaps you want "~=" instead of ".="? Since ".=" is a call of method with assignment. And I don't understand fully your "->", what should it mean?

ZzZombo is there any writing how to write a serializer for recursive data type that preferrably won't hang on anything bigger than a few elements in it? 12:55
timotimo is JSON::Fast not fast enough? 12:56
ZzZombo But I'm not serializing into JSON. I want to save parsed and probably changed data back into source form. 12:57
timotimo there's nothing for you on modules.perl6.org?
there's serializers for XML, TOML, Serialize::Naive and Serialize::Tiny are probably something proprietary? then there's PerlStore, no clue what that is, and there's all the JSON ones, and there's something called "Avro" 12:58
apache avro, eh? 12:59
12:59 firefish5000 joined
ZzZombo I have a different format, not one of those widely used. 12:59
timotimo oh, so you're forced to comply with a given format 13:00
i didn't realize that
13:00 sammers left
llfourn_ ZzZombo: just recursively walk your data structure and return objects after visiting each node. 13:00
timotimo llfourn_: that's not fast :)
llfourn_ does it need to be fast? 13:01
timotimo that's how JSON::Tiny does it. JSON::Fast has something a bit more efficient
13:01 girafe joined
timotimo yes, he said he wants one "that preferrably won't hang on anything bigger than a few elements in it" 13:01
ZzZombo and that just blew my computer up. Did you notice I've timed out.
timotimo though i have no idea why something would "hang" with more than "a few elements"
i did not notice that
you probably infinitely recursed instead of making progress
ZzZombo well, I had to reboot. Now I'm gonna run tests under a VM, I guess. 13:02
timotimo just set a ulimit
13:02 bjz joined
ZzZombo ulimit? 13:02
timotimo yup, check out ulimit -a

timotimo watch out, though, the "maximum resident set size" option is usually not implemented 13:03
ZzZombo that's for Unix though, isn't it? 13:06
timotimo oh, you're on windows? 13:08
ZzZombo yep 13:09
moritz you could use Perl 6 in docker, and define some resource limits on the docker level
timotimo how well does docker work on windows?
llfourn_ doubts the computer is hanging because of FDs
timotimo and can you use ulimit on "ubuntu on windows10"? 13:10
llfourn_ docker should work pretty well on windows. It uses HyperV now from what I heard. 13:12
13:13 sammers joined
IOninja ZzZombo: .= is a method call and you can provide the method name in a string; in which case you need parens after it. 13:25
firefish5000 I cannot figure out whats up with my grammars, the smallest changes seem to grossly affect the output. (for instance, adding {say 'fix'} into the non-working token may cause to to finally correctly match)
IOninja m: my $x = 'meows'; $x .= 'uc'() .= 'flip'(); say $x
camelia SWOEM
moritz firefish5000: a {} block delimits longest-token matching 13:26
so it's legitimate that it can affect outcomes
IOninja hchienjo, I'm guessing you've read a particular article to know of that name... Keep in mind not everything is entirely true on the Internet. 13:27
firefish5000 oh, that explains why my debugging attempts have been failing so miserably! Thanks moritz 13:28
moritz firefish5000: are you aware of Grammar::Tracer?
IOninja toolforger, angled brackets in that case a Rat literal. Only the Num view of a Rat follows IEEE floating point rules; so for example 0/0 + 0e0 won't explode, but 0/0 + 0 will
moritz firefish5000: <plug type="blatnat">the grammar chapter of leanpub.com/perl6 might interest you</plug> 13:29
(though I don't talk much about LTM in there, TBH) 13:30
llfourn_ things do become much easier once you get used to LTM
firefish5000 yes, and I use it extensively. but I wasn't aware my code blocks affected the output. I will need to re-read up on grammars. thanks!

15:57 risou_awy is now known as risou
IOninja Looks like the IO grant will do some major changes. And some things are documented, despite there being zero tests for routines. Their behaviour is undesirable and since there's no roast to block the changes, I'll make them... 15:59
Gonna draft an advanced notice telling users wtf's happening. My ETA for these changes going in: 2017.04 Rakudo and Star releases. 16:00
s/draft/publish/;
(Re documented without tests: it's 'cause they were documented prior to our implementing a policy of not doing that)
moritz it would be really awesome if old-style IO and new-style IO could coexist for a while, to ease the transition 16:01
IOninja Don't see a good way to do that.
MasterDuke do any of the modules currently in the ecosystem use the stuff that's going to change? 16:02
IOninja The release will come with detailed upgrade guide ("if you're using X, you're supposed to be using Y") and I'll publish an announcement basically a realease and a half in advance, so IMO it's not as bad. 16:03
16:04 kurahaupo left

ZzZombo what is better to put in alternation first, something that is gonna succeed often or fail quickly? 16:07

IOninja A problem tho: (a) a module updates for new changes; (b) user uses the module with an older compiler. 16:24

IOninja The devs have free pass to make these changes since our contract with the user is: we don't break 6.c-errata tests. And we won't. 16:25
16:25 itaipu left
IOninja In reality: our tests in this area are crap and users are using stuff they think won't change. 16:25
Plan C: delay this until 6.d; but then all the books being published right now will be heavily outdated and wrong in just a few months after their publication. 16:26
mst surely the books should be targeting 6.d ? 16:27
IOninja Well, the .seek change can at least be done while still supporting old interface. No one seems to be using `link` anyway. I guess I'll publish an advance notice and we'll decide what to do on any other things that'll pop up. 16:28
mst: they will be published before 6.d. We don't even know when 6.d will happen yet.
mst ah
if we're fixing up I/O can we have unix socket support now? 16:29
IOninja Not as part of the grant, because I don't know what that even is. But I saw enough people ask about it that I'll look into it after the grant. 16:30

i think i just did that because the json for them was empty, but i'm not going to swear to that 19:23
timotimo yeah, makes sense 19:24
but we only make those empty because that's cheaper than to put the key in and set its value to 0
MasterDuke ah, ok. then making the sql output 0 does probably make more sense 19:27

BenGoldberg wonders if it would be a good idea to have a perl6 builtin uniname-like(Str --> Seq). 21:12
Iterating through all unicode points to find the ones which match something seems a bit silly. 21:13
21:13 itcharlie joined, itaipu joined
BenGoldberg Otoh, searching a unicode database file for a specific string, then backing up the beginning of the line and capturing to the end of the line, seems like a much more efficient proposition. 21:14
moritz in some real-life examples, it looks less jagged when I just assume everything is one character wide than when I assume my width() sub is correct 21:15
BenGoldberg: it takes less than two seconds to do search through all character names, so I find that acceptable for my use case 21:16

moritz I just wrote "codepint" instead of "codepoint". Not a pun I ever made intentionally. 21:24

timotimo that's a named argument

timotimo haha :D

timotimo well, an object hash is with Any keys 23:57
m: my %hash := Hash[Mu,Mu].new(); %hash.push: (Mu) => 5; dd %hash
camelia (my Mu %{Mu} = (Mu) => 5)
timotimo there you go
MasterDuke timotimo: what do you mean "every node in the callgraphe unique"? you mean something like give every table a new autoincrementing primary key?
IOninja Ohhh
BenGoldberg m: my %hash := :{}; %hash.push: item Failure.new('blah') => 5; dd %hash;
camelia :{(Failure.new(exception => X::AdHoc.new(payload => "blah"), backtrace => Backtrace.new)) => 5}
timotimo not every table
at the moment you can have many entries in callees where "id" matches
anyway, i'm not so sure you can properly reconstruct the call graph just from the sql 23:58
