codesections why do the $0 capture group ^^^ have multiple matches in it? I would have expected just one in each execution 12:45
s/do/does 12:46
moritz codesections: you actually get several matches, each with their own $0 12:52
codesections Yeah, I see that. But, unless I'm misreading the output, each of the $0 (except the last) has two matches 12:53
moritz you are misreading 12:54
I recommend you print each match on a separate line in the terminal, it will be easier to see that way

maybe a LTA print representation?
moritz it's pretty good actually, if you take care that each output starts on a new line 13:04
codesections Hmm? The thing I was saying is LTA is that each output *doesn't* start on a new line. 13:05
13:05 aborazmeh joined
moritz well, but that's because you're not using say() 13:05
13:05 aborazmeh left, aborazmeh joined
moritz just do it, and you'll be fine 13:05
gist.github.com/moritz/698e186c9fb...8f0bbf7588 13:06
or even add \n before you output the match 13:07
codesections yeah, I get that. I was saying the *default* print representation for `say 'a1a2a3a4a5' ~~ m:g/(a \d)/` isn't great ā€“ because that prints without the newlines 13:08
moritz agreed 13:09
but there isn't much we could do
that wouldn't also break some other use case
codesections Interesting. Why is that? `say` there prints with `.gist` ā€“ I thought `.gist` was free to print however it liked without breaking anything? 13:10
Or would it break things in the sense of displaying poorly?
moritz well, say gets a list
we could of course say that .gist on a list joins by newline 13:11
but then something like
m: say <a b c>
camelia (a b c)
moritz would be *much* more verbose
or we could say that Match.gist adds newlines (leading or trailing), but then the *far more common* use case of simply doing "say $/" now contains unnecessary whitespace 13:12
codesections: what would be your suggestion on improving the situation?
codesections I was thinking along the lines of the second suggestion. If `Match.gist` added a trailing newline, wouldn't that be good whenever `$/` returns more than one match? And when $/ returns 1 match, it'd just cost 1 newline 13:14
moritz IME a single mach is by far more common than multiple matches 13:15
and it makes sense to optimize for the common use case
codesections Agreed 13:16
I guess I thought one extra newline wouldn't be much of a loss: the problem with newlines in `say (a, b, c)` is that it gets really verbose, but one newline doesn't really cause that problem. 13:17
But yeah, if we view the extra newline as a problem, then there's no good way to fix the uncommon case without messing up the common one
ĀÆ\_(惄)_/ĀÆ 13:18
13:20 domidumont joined
codesections (a more radical solution that I personally like but wouldn't advocate for is to change `List.gist` to print commas between the list elements. But that's too big a change to make sense as a fix here ā€“ I'd just like it :) ) 13:20

Add article for RFC 5
codesections Actually, moritz: what would you think about printing Matches with a delimiter? e.g., changing .gist to print like: 13:33
m: say ('a1a2a3' ~~ m:g/(a \d)/).map({'{' ~.gist~ '}'})
camelia ({ļ½¢a1ļ½£
0 => ļ½¢a1ļ½£} {ļ½¢a2ļ½£
0 => ļ½¢a2ļ½£} {ļ½¢a3ļ½£
0 => ļ½¢a3ļ½£})
codesections Matches *aren't* associative, but they "feel" a bit like an associative object 13:34
which is why I used `{ā€¦}` in the example. But it could be other delimiters 13:35
moritz m: say Match ~~ Associative
camelia False
moritz m: say Match ~~ Positional
camelia False
moritz slightly surprised
13:37 aluaces left, aborazmeh left

gfldex guifa2: not from the object that has received the mixin. You could create a new object that is a partial clone. 16:02
16:05 andrew left
guifa2 gfldex: hmm, creating the new object is the tricky bit. I'm being evil and wrapping new ^_^ 16:10

tony-o dakkar: i'm fleshing that grant proposal out a bit more this morning. anything in particular you'd like addressed about the API ? 16:17
disregard - i see comments on the link moritz posted 16:18
dakkar yeah ā˜ŗ and here
essentially, having "just a bunch of files" makes plenty of uses simpler 16:19
of course, some of those files will be indexes
16:19 melezhik joined
dakkar but the fact that I can create a local cpan mirror with just a call to rsync is powerful 16:19
by all means, fancy APIs like metacpan are awesome 16:20
melezhik Hi rakuers! If someone is into kubernetes stuff here? I've created a Sparrowdo scenario to deploy k8s cluster from the scratch using aws infrastructure
github.com/melezhik/sparrowdo/blob...s/k8s.raku
dakkar but having to install indexers, servers, &c to serve my own distributions feels like a sub-optimal design to me
melezhik I am going to give more details in the next RakuOps issue 16:21
tony-o there won't be much of a change from that type of structure except to handle the :auth:ver etc
the api is mostly around account creation/uploading
dakkar ok, so it's a PAUSE-like API 16:24
and the repository stays CPAN-like
and `zef` doesn't need an index server, it keeps fetching the whole index file and reading that 16:25
+1 from me

tony-o [Coke]: i'll be adding some and responding to your comments this morning too 16:31
is it appropriate to just respond in comments or is there a way to amend the proposal?
moritz tony-o: you write an email to Jason Crome (TPF secretary who posted the item on the blog) and supply him with an updated version 16:38

demostanis I'm having some weird issue with regexes (again), $m.Str where $m ~~ Match seems to return a string of the match, INCLUDING ignored stuff, is this is intended behavior? I am going to try to write up an example... 21:23
In a grammar, I have a token value { [ <thing> | <other-thing> | <.ignored-thing> ]* } 21:24
In the grammar's actions, I am trying to get the $<value> as a string using its .Str method, however the result includes stuff matched by <.ignored-thing> 21:25
skids <.ignored-thing> just doesn't create a submatch. It doesn't exclude the text that matched ignored-thing from the outer token. 21:31
demostanis How would I make it exclude that text? 21:32
codesections If I understand what you're trying to do correctly, try something like this: 21:33
m: 'AAABBBCCC' ~~ /<(['AAA' | 'BBB')> | 'CCC']*/

gfldex guifa2: Raku is less dynamic that it might look. You just made that show. 23:01
guifa2 Indeed. I'm finding lots of little gotchas when working with natives. 23:02

camelia No such method 'gist' for invocant of type
'Perl6::Metamodel::ClassHOW+{<anon>}'. Did you mean 'isa'?

elcaro lizmat: Hash2Class is nice. I'm not sure if it's of any interest to you, but there's an intersting talk by Rich Hickey about schema (and something called 'spec') in Clojure 23:51
It's about validating that the data in a Hash looks a certain way. I was thinking of building something like that but Hash2Class pretty darn close 23:52
here's the talk, if interested: www.youtube.com/watch?v=YR5WdGrpoug
I'm not a Clojure user, but it's still interesting... and potentially would still be a useful thing to build. Do we have something in ecosystem that validates the shape of - and types in - a Hash? 23:53
