RabidGravy boom 10:20
azawawi my eyes... :)
RabidGravy: one of the thing that worries me about GTK::Simple is the usage of the GTK::... namespace 10:21
RabidGravy: github.com/perl6/gtk-simple/tree/master/lib/GTK
RabidGravy: namely GTK::GDK and GTK::NativeLib
RabidGravy yeah, I've thought that about other modules too 10:22
I was going to write something up about avoiding doing that
my general feeling is that for a given module Foo::Bar then you should attempt to only use the Foo::Bar::* namespace, otherwise it potentially blocks out someone else using Foo:: 10:25
Ulti also there was a trend of calling nearly everything for Perl 6 thats the first implementation pass "Simple" rather than it just being the first version of the real deal
10:26 TEttinger left
Ulti ::Simple was meant to mean something about the API not the authors attitude to their own work :3 10:26
RabidGravy which is probably a hostage to fortune to be honest
hahainternet i do think that Go's adoption of an import path being the authoritative name is quite lovely
so good luck using 'github.com' as your namespace 10:27
Ulti I thought the way P6 packages worked is you had namespaces broken down by authority anyway
RabidGravy well if we could uniformly use the module long name everywhere then it wouldn't be a problem
pmurias Ulti: +1 using ::Simple how it was orginated in Perl 5 10:28
Ulti DBIish also >:P I always forget if its one 'i' or two, if you dont know what DBI was then its a bad name and if you do then you wonder why its not just DBI here and if there's meant to be a real one coming 10:32
10:32 grondilu joined
Ulti its an ecosystem of doubt :Z 10:32
pmurias is a real one coming? 10:33
Ulti fairly sure we can defacto say it is the real one, especially since its really functional 10:34
nine Well a new one with a redesigned API was in the works back then.
jnthn fwiw, GTK::Simple was originally written by me, for the purpose of demonstrating how supplies are a really nice way to deal with UI events. I didn't really think about how to make it handle all of GTK (knew I'd no way have time for that), so it was meant to handle simple use cases. :) I'm happy it's now in hands other than mine, but if it's going to support All The Things then a name change is likely sensible :) 10:35
azawawi starts reading developer.gnome.org/gtk3/stable/ :) 10:36
Ulti nine I guess with Inline its nice to have the name be different too 10:38
pmurias Ulti: Tim Bunce had plans how the Perl 6 version of DBI would look like (with a JDBC style standardized api for backends), it's understandable that people didn't want to "steal" then namespace from him 10:42
Zoffix .seen stmuk
yoleaux I saw stmuk 24 May 2016 09:56Z in #perl6: <stmuk> something like that is better
Zoffix Don't we have :auth<> stuff? :)
stmuk Zoffix: just saw this buffer! 10:43
Ulti ^ this
DBI:auth<tim> would have been that one, with a major version number bump ahead of what anyone else was doing?
I thought that was meant to be the Perl 6 way of handling the namespace camping issue? 10:44
I guess at the time we didnt have much versioining in modules either :) 10:45
as in the ability to do it
Zoffix Well, version is supposed to irrelevant. :auth stuff alone is sufficient.... were people to actually use it.
Ulti well the version number bump makes it easier to discuss since you could say DBI 2 rather than DBI-the-tim-bunce-one 10:46
Zoffix heh
10:46 andreoss joined
Ulti authority is more often going to be you trust someones patches and release schedule rather than its a fork or parallel project you'd hope? 10:47
10:48 skingsbu joined, skingsbu left
Zoffix I'd think it's more to prevent stuff like this: (4 top results): metacpan.org/search?size=20&q=...pe=modules 10:49
:auth basically gives each author an ability to name their module anything they want, regardless of what other authors name their stuff. 10:50
It also creates a problem that without :auth, you may or may not get what you want :/
Zoffix foresees module installers having a "trusted authors" list in the future 10:51
stmuk, if you have no idea why perl6.party desn't show up on pl6anet, then I could try replicating another feed to-the-letter... I just didn't wanna do the work if I didn't have to :) 10:53
And if all else fails, I guess we can revert it back to blogs.perl.org :/

Seems like an array just has some extra methods to it. 14:35

camelia rakudo-moar a5c46b: OUTPUT«Blob[uint8]:0x<66 6f 6f>␤»
psch ah, right, immutable
AlexDaniel m: my Buf $x = Buf.new(104, 101, 108, 108, 111); say $x ~ ‘ world’
psch nicqbot: a Buf is a mutable Blob. as in, binary data
camelia rakudo-moar a5c46b: OUTPUT«Cannot use a Buf as a string, but you called the Stringy method on it␤ in block <unit> at /tmp/XPWlfax8gw line 1␤␤»
ZoffixW nicqbot, Buf is for binary data. Array is for itemized values. Hence the difference in methods. Sure, you can represent many things inside an Array, including strings, but it's better to have a specific type.
AlexDaniel docs claim that it is Stringy
psch m: my $x = Buf.new(70, 79, 79); say $x.decode('ascii');
camelia rakudo-moar a5c46b: OUTPUT«FOO␤»

RabidGravy the thing about this is that when the expression is a type or a whatever it adds a fallback method to do it rather than explicitly adding a method 16:27

azawawi RabidGravy: the on-the-fly XML to Class file translation in BEGIN { ... } looks cool until you have big UI projects with many dialogs/windows/components. It adds up to the cost of compiling Perl 6 code and slows down the work of IDEs trying to show errors 18:49
RabidGravy yeah, I'm not that keen on that part 18:50
azawawi RabidGravy: and you need to look at the timestamp of each glade file in question which adds more I/O
RabidGravy: Generating stuff in glade is done once at the start of a project to speed up development and then no one really uses it for maintenance 18:52
RabidGravy: though i could be wrong ofcourse 18:53
azawawi reads developer.gnome.org/gtk3/stable/GtkBuilder.html 18:54
RabidGravy I actually don't find glade any easier than building it by hand 18:55
geekosaur I thought glade got you some isolation from gnome3/gtk3 folks changing everything at the drop of a hat 18:56
azawawi RabidGravy: so more complete widget support is more important than glade translation support atm. I see. 18:57
geekosaur (that is, that was the main reason to prefer glade)
RabidGravy yeah, you'd need to support all the widgets to be able to use glade properly anyway 18:58
azawawi so why not create another project for glade XML -> class translation? 18:59
RabidGravy that would be cool
azawawi GTK::Simple -> widgets wrapper and App::GladeTranslator is a separate effort 19:00

dha Oh, and FWIW, I took a look at the grammar (I'm clearly insane). I still have no idea how :w and :ww figure out what are quotes. 21:30
geekosaur has seen worse grammars... 21:31
21:31 Zoffix left 21:38 xtreak_ left 21:45 willthechill left
dha Oh, I'm sure. 21:47
psch dha: what do you mean "what are quotes"? 21:49
dha There's been discussion on how qqw and qqww work wrt quote preservation. In that context, what counts as a quote? 21:50
psch dha: did you see role ww? 21:51
dha straight quotes, curly quotes, japanese quotes all seem to work. But I think there should be an official description
yep. and japanese quotes, although they are considered quotes in this conext, apparently, are not listed there.
(AFAICT) 21:52
psch oh, that's the weird angle-y things, right?
like, the ones that Match.gist uses
dha Yep.
psch m: say "a" ~~ /(a)/ # just to have them for searching
camelia rakudo-moar a5c46b: OUTPUT«｢a｣␤ 0 => ｢a｣␤»
psch token metachar:sym<'> { <?[ ' " ‘ ‚ ’ “ „ ” ｢ ]> <quote=.LANG('MAIN','quote')> <.SIGOK> }
ah, that's in RegexGrammar 21:53
dha ...and looking at role ww doesn't give any indication that I should be looking there (again, afaict). 21:54
So figuring out what the *actual* answer is to this, is, IMO, not obvious. (maybe someone who understands the grammar better than I do would be able to figure it out, but... I dunno). 21:55
psch dha: well, afaiu, QGrammar is what parses every q//
dha: and the adverb determin which of the roles inside of QGrammar are applied
+e
21:56 AlexDaniel joined
psch role ww says "if we are :ww, everything that uses one of these quote characters gets a new QGrammar with these roles instead, until we hit FAILGOAL 21:56
"
AlexDaniel .

 21:57
dha psch - great. So where does it say "look at RegexGrammar too!"
?
:-/
Also, I'm not really sure how to parse that line you posted from RegexGrammar 21:58
So... I still don't know how to answer the question. Also, since I don't know how RegexGrammar figures into this, I also don't know if there's something *else* that affects this.
Etc. Etc.... blah.. blah... :-)
psch dha: well, it declares a metachar token with the symbol <'> that can be any of those quotes, and inside switches to the quote language 21:59
s/can be any/gets matched when any of the opening quote characters match/
dha: so, basically, it states that where that rule is in effect a metchar that would match ' can also match e.g. ｣ 22:00
err
the opening one of those two.. :)
of course, that doesn't explain how that goes from Perl6::RegexGrammar into Perl6::QGrammar 22:01
dha Right.
which, again raises the question, what *else* might go into Perl6::QGrammar. :-/
Keep in mind, here, I JUST VOLUNTEERED TO WRITE SOME GOLDARNED DOCUMENTATION 22:02
;-)
psch ...so what's the documentation-level question? :) 22:04
dha when :w does quote preservation... what counts as a quote? 22:05
psch everything that also counts as a quote in the main language
dha (or, conversely, when :ww *doesn't* do it)
psch m: .say for <a <b c>>
camelia rakudo-moar a5c46b: OUTPUT«Value of type List uselessly passed to val() in block <unit> at /tmp/k7duwuvbLL line 1␤a␤<b␤c>␤»
psch grr
dha Great! What are those things?
psch well, except for "end and start character is identical" i suppose
if you want to pull that out of the grammar, it's all the "token quote:sym<..>" declaration 22:06
or you can hope someone volunteers to do that for you... :) 22:07
well, i suppose not all
e.g. token quote:sym<q> is the q// (without the //) construct
dha Aha.
psch eh, it's a bit more involved, anyway :/
like, quote:sym</ /> is obviously QRegex, not QGrammar 22:08
dha So, the stuff under 'proto token quote', then.
psch on a glance, apos, sapos, lapos, hapos, dblq, sdblq, ldblq, hdblq, crnr
those are definitely all variations on q// or qq// 22:09
dha (until the <q>, at least)
ok. *that* seems to be what I was trying to find.
No idea where to put it in the docs, but at least I know where to find it now. 22:10
psch in general, looking for 'nibble(self.quote_lang' is a good hint, yeah
