flip913 masak: short question allowed? 13:05
masak flip913: sure. 13:06
flip913 I saw in use.perl.org/~masak/journal/
zarah flip913's link is also tinyurl.com/6csgre
flip913 this line: $c.send_response(&app(%env)[2].Str)
masak yes? 13:07
flip913 but .Str puts spaces between the elements of the list doesn't it?
masak oh, er.
rakudo: say <a b c>.Str
flip913 So ['<div>','<span'>] would end up with whitespace ... which changes the meaning a bit.
p6eval rakudo 0d4fe0: OUTPUT«a b c␤»
masak flip913: you're completely right.
thanks for that.
rakudo: say ~<a b c>
p6eval rakudo 0d4fe0: OUTPUT«a b c␤»
masak hm. 13:08
rakudo: say [~] <a b c>
flip913 Ain't there an attribute to .Str?
p6eval rakudo 0d4fe0: OUTPUT«abc␤»
masak that's probably what I want.
flip913 And, is there a way for streaming output?
So I can send eg. javascript lines to update some progress information?
masak flip913: can I attribute the fix to you in an edit to the blog post?
flip913 Of course. But 913 is just some random number for uniqueness ... 13:09
masak flip913: I got the streaming output question during my YAPC talk as well.
flip913 Yes, that was me ;-)
masak flip913: I'll call you whatever you want in the blog post. :)
flip913 So: do you have any plans for the other list elements, after the array ref? 13:10
masak flip913: I'm planning to field your question to #rack when I have the tuits.
wayland76 flip913: Tell him you want to be called "O great and worshipful master" :)
flip913 If not, how about looking at the elements, and if they're Callable, just run them?
masak flip913: I'm not in a position where I want to just extent the protocol we have right now. 13:11
flip913: also, I'm pretty sure Rack has some prior experience in this area.
I plan to ask them first.
flip913 And, btw:
rakudo: my @a=1,2,3,[1,2,,,3], 4; say [~] @a; 13:12
p6eval rakudo 0d4fe0: OUTPUT«1231 2 34␤»
flip913 there are spaces again
rakudo: my @a=1,2,3,[1,2,,,3], 4; say @a.Str; 13:13
p6eval rakudo 0d4fe0: OUTPUT«1 2 3 1 2 3 4␤»
flip913 rakudo: my @a=1,2,3,[1,2,,,3], 4; say @a.Str('');
p6eval rakudo 0d4fe0: OUTPUT«too many arguments passed (2) - 1 param expected␤in Main (/tmp/l5V3zSN7GF:2)␤»
masak flip913: well, the elements of &app(%env)[2] should be Str, so... 13:14
flip913 Well, but appending to a single array might be bad for performance ... if some functions just return their own arrays, and I just push their reference onto my output array, that scales better, I think. 13:15
And it works for .Str ... only the delimiter has to be removed.
rakudo: my @a=1,2,3,[1,2,,,3], 4; say ''.join(@a);
p6eval rakudo 0d4fe0: OUTPUT«␤»
flip913 rakudo: my @a=1,2,3,[1,2,,,3], 4; say @a.join(''); 13:16
p6eval rakudo 0d4fe0: OUTPUT«1231 2 34␤»
flip913 Hmrpf ...
I'm just looking at aspn.activestate.com/ASPN/Mail/Mess...ge/2630896

flip913 rakudo: my @a=1,2,3,[1,2,,,3], 4; say @a.join; 13:17
p6eval rakudo 0d4fe0: OUTPUT«1231 2 34␤»
masak flip913: no, the Rack spec says they have to be Str.
flip913 But, as I just mentioned, might not scale.
masak at least I think it does. 13:18
I agree about the need to think about what might and might not scale, but I don't think we should try and fight invisible enemies at this stage. 13:22
our current problem is not scalability, but speed in general.
flip913 Sorry, had to answer somebody. 13:30
masak flip913: updated blog entry use.perl.org/~masak/journal/39475 and pushed a patch to Web.pm. thanks! 13:31

push is not entirely linear 13:33
I've seen some projects that had to try clever things, like stringify return values, and pushing them on arrays, and so on 13:34
ain't it possible to 'enhance' the Rack specification? Embrace, extend, ... as they say 13:36
rakudo: my @a=1,2,3,[1,2,,,3], 4; say @a.cat; 13:37
p6eval rakudo 0d4fe0: OUTPUT«Method 'cat' not found for invocant of class 'Perl6Array'␤»

masak flip913: of course it's possible to extend the Rack spec. my point is just that I don't think it's time for that just yet. 13:41
I consider the Rack spec to be something very stable. they hit 1.0 in February this year.
flip913 Update: nopaste.snit.ch/17595 push nearly linear. 13:44
Let's keep it at that, at least ATM. Thank you!

flip913 @tell masak stone the cows - revert that last thing, I solved both problems. 20:57
zarah Consider it noted.
flip913 @tell masak Does the Rack standard say "Array"? 20:58
zarah Consider it noted.
flip913 @tell masak Or can it just be a list - possibly infinite?
zarah Consider it noted.
flip913 @tell masak then just pass the list to sendResponse(), and some levels down some code has to iterate over the list and send each element 20:59
zarah Consider it noted.
flip913 @tell masak then we just put a lazy list there - ie. something "does Iterable" or suchlike.
zarah Consider it noted. 21:00
