rfold antoniogamiz: see also bugzilla.mozilla.org/show_bug.cgi?id=668213 07:47
Seems to be due to an eight year old bug in Firefox.

thanks!

rfold So it probably works fine already in Chromium. 07:58
antoniogamiz yep, it does 07:59
rfold If you set autofocus in onload, does it actually set focus though? Because autofocus only sets focus during loading AFAIK. 08:00
antoniogamiz ups, you're right. I should set focus instead
08:01 aborazmeh joined, aborazmeh left, aborazmeh joined
rfold You could set focus only if location.hash is missing or equal to '___top' I suppose. 08:02
er, '#___top'
antoniogamiz done :) 08:06
rfold Cool :)
Can't wait for this fix to be live, it's been bugging me so much.
antoniogamiz how do you manage the messages of your app? do you think make a logger class with different levels of debugging is recommendable? 08:08
I mean, I have different kinds of messages and sometimes some of them needs to be disabled 08:09
so I though that I have a class where several general methods to print those messages, I can disable them there 08:10
s/I have/to have
rfold My approach to logging has always been passing around a function that takes a log message. Then the callsite can wrap this function in another function that does additional processing, e.g. filtering or adding more information. 08:11
antoniogamiz mmm can you show me an example? 08:12
rfold If you don't like passing around arguments then you can use a &* variable.
Yeah sure.

rfold antoniogamiz: glot.io/snippets/fe8143bqqq this uses Str for messages but you could use something more elaborate like a message type that has a level and timestamp and metadata for example 08:18
If you have two loggers &foo and &bar you can combine them like this: sub foobar($msg) { foo($msg); bar($msg); }
This will log to both loggers, e.g. to stdout and to syslog.
antoniogamiz :oo 08:20
thanks a lot rfold!
rfold If you don't like passing it around you can do this: glot.io/snippets/fe817qemj7 and you could write functions like sub log that set the level for you, e.g. sub info, sub warning 08:21
08:22 Imoh joined, Manifest0 joined
antoniogamiz mmm I like that :) 08:23
rfold And these are useful: glot.io/snippets/fe819gresx . We use this approach at work and it's nice because the logger isn't global, thus the caller can easily customize the way that the callee logs things. (Although we use Haskell not Perl 6, but it should work just fine.)
08:24 Imoh left
antoniogamiz I like that even more :oooo 08:25
rfold Other possible combinators include: catch exceptions that occur during logging, make a logger thread-safe with channel or lock, logger that ignores all but the first message, logger that accepts numbers and adds them to a counter (we use this for progress reporting) 08:26
08:27 redhands left
rfold And log message throttling is very useful for high volumes 08:28
antoniogamiz uoh, good 08:29
thanks a lot for your tips :) 08:30

kshannon Is there a way to re-dispatch to the current proto sub? I can't use nextwith as the arguments match a completely different set of multi candidates. 08:38
And while I'm on the subject of multi-dispatch, was there a rationale for making missing optional named arguments more specific than a candidate without the named argument? 08:40
I'm guessing it's probably just a consequence of the actual dispatch rules but I can't seem to find a good description of what those rules are on docs.perl6.org 08:42
antoniogamiz maybe you should raise an issue to clarify that part 08:44

jnthn antoniogamiz: Yes, for a task you should either pass a block of code to execute, which determines the duration of the task, *or* you can use `.start` and then call `.end` on the object you get back if you have a more complex situation (for example, the start and end are in completely different bits of the code) 12:27

ugexe i'm not sure you can avoid those problems of multiple versions without having a good understanding of your dependencies (something a developer *should* have anyway if you ask me) 17:36

vrurg How is it supposed to work? Any link for a paper/discussion? 17:41
ugexe but to rebuttal -- someone made poor choses for the project
just because a module exists and does something you want is not a valid reason to use it 17:42
it must also be e.g. secure
in other words: im of the opinion the user is the only one who can get themselves out of that problem period 17:43
timotimo i wonder if we'll ever have something comparable to html's Subresource Integrity, or how you used to import stuff from .net in niecza, with a hash in the identity; i think that was perhaps for a pubkey? or maybe a hash of the code or something?

camelia ()
ugexe m: $*IN.out-buffer(1); # I would guess this
camelia Too many positionals passed; expected 1 argument but got 2
in block <unit> at <tmp> line 1
ugexe obviously im wrong
JappleAck yeah, that's only i found by "buffer" word 18:11
ugexe well, maybe its $*IN.out-buffer = 1
m: $*IN.out-buffer = 1
camelia ( no output )
JappleAck it's a "method" as i see in the docs, not "property", but i'll try it 18:12
doesn't help
ugexe its an rw method that returns a proxy 18:13

camelia True
vrurg m: say $*IN.^methods.map(*.^name).grep: *.contains("buffer")
camelia ()
vrurg m: say $*IN.^methods.map(*.name).grep: *.contains("buffer")
camelia (out-buffer)
ugexe .open(:out-buffer(1)) works for filehandles at least 18:15
vrurg ugexe: over-use of .^name always plays this trick with a Method object. ;)
ugexe are you sure you don't want $*OUT.out-buffer = 1 ? 18:16
$*IN.open(:out-buffer(1)) might be worth trying 18:17
Xliff vrurg: What constitutes overuse of .^name? 18:19
vrurg Xliff: In my case it's a lot of introspection while debugging. 18:20
JappleAck i tried this: `my \IN = $*IN.open: :1out-buffer;` but when i do `IN.readchars(1).say` it reads only when i press enter 18:21
ugexe wouldn't it have to wait to press enter so it knows it can try to encode the string? 18:22
vrurg JappleAck: you probably need getc method 18:27
18:27 patrickb joined
ugexe still requires an Enter press 18:28

JappleAck is there any equivalent of $| from perl5? 18:30
vrurg JappleAck: Term::termios is what you need. 18:31
JappleAck: waiting for enter is not about Perl6 buffering, it's how terminal works.
In perl5 read STDIN, $c, 1 would do the same for you: wait for enter, then get 1 char. 18:33

JappleAck i found a way to run `/bin/stty raw` first 18:41
but i don't know how to change it back to default value 18:43
vrurg termios is better because it doesn't use external processes.
stty sane must work.

MasterDuke thundergnat: there was a recent example where 90% of the time was spent in stringifying a big Int. since you did so much with stringifying (Fat)Rats, you might be able to evaluate this and see if it could help code.activestate.com/lists/tcl-core/13692/ 20:14
discord6 <Tyler (Aearnus)> dumb question, but I can't for the life of me figure out what : does when you're calling a subroutine 20:17
MasterDuke a : where? 20:18
TreyHarris Tyler (Aernus): I'm pretty sure you mean cases like `say (1,[1,2],"foo",Mu).map: so *.say ;` in Mu's docs? 20:23
That means you're calling a method like it was a subroutine
It's often used for its precedence more than for its actual functionality; in the case of map, for instance, using a colon lets you skip the parentheses, which would be annoying otherwise), so for instance, the above could be written `say (1,[1,2],"foo",Mu).map(so *.say,)` 20:29
m: say (1,[1,2],"foo",Mu).map: so *.say ; 20:30
camelia 1

TreyHarris m: say (1,[1,2],"foo",Mu).map(so *.say,)

timotimo we're making them a thing again! 20:32
20:32 Black_Ribbon joined
TreyHarris @Tyler (Aearnus): The precedence thing, if it wasn't clear, is a bit like Haskell's $, if you're familiar with it. Or "and" and "or" vs "&&" and "||" -- you can say "complex stuff or die sprintf(...)" where "complex stuff || die sprintf(...)" would do something strange 20:34

noisegul Can somebody help me determine a return type? A method is supposed to return an Array of objects, calling `.^name` and `.first.^name` print what's expected, but looping over the result and accessing objects won't work, neither does appending to an Array of the same type the result is supposed to be. Commented example here: gist.github.com/noisegul/b049fd382...55b104f99d 20:45
timotimo noisegul: looks like the array returned by registry.lookup is in a container 20:46
and that makes the for loop only do a single iteration, which passes the whole thing into $r
20:47 Manifest0 joined
noisegul I see, that's why the second for loop example works, but not the first 20:48
TreyHarris noisegul: It's almost the definition of the difference between the $ and @ sigils 20:49
timotimo either put a .list at the end before the -> $r or make lookup return something non-containerized
noisegul I see, what would the return type annotation for .lookup be in that case? Or does that still fall under `Array[TYPE]`? 20:51
timotimo it does
noisegul Alright, makes sense, thanks for the clarification! :) 20:52
TreyHarris Where is .lookup defined, anyway?
noisegul It's from a different module 20:53
TreyHarris noisegul: which, though? I'm having trouble finding it working from github.com/antoniogamiz/Perl6-Documentable 20:54
