Remove some incorrect statements from the Grammars article

The dynamic variables section stated that grammars behave like classes, but they don't; they have a completely different metamodel.

kawaii Has anyone got a good way of tracking uptime in a daemonised perl 6 app? :) 01:01

kawaii in the meantime, still learning p6regex, `if $id ~~ / ^'<@' '!'? \d+ '>'$ | ^\d+$ / { say 'yes' }` I don't know if I'm being too verbose - but $id is a param passed into the method, and I'd like to set the value to JUST the \d+, but still match and extract the \d+ from the first match which contains the entire 'tag'. 12:27

kawaii based on the help jmerelo gave me earlier, I wrote a method! www.irccloud.com/pastebin/FsEsssyy/ 13:35
but, $/.Int does not seem to behave as expected
because $/'s type is Match 13:36
and I don't think it can be coerced
13:36 pat_js left
kawaii It also seems to not be stripping the characters I do not want to match 13:36
timotimo in that case you may have to .Str.Int 13:39
timotimo actually looks at the code
you can't .Int it because it's got some junk around the number
kawaii yeah, but my smartmatch should eliminate that, no?
timotimo you're already using ( ) around the \d+, which means you'll probably want to use $0 and $1 instead of $/ 13:40
kawaii so $1 for the result of the ()?
timotimo m: say "<\@1234>" ~~ / '<@' '!'? (\d+) '>' | (\d+) /;
camelia 「<@1234>」
0 => 「1234」
kawaii because $0 would be the entire thing that matched I assume
timotimo m: say "1234" ~~ / '<@' '!'? (\d+) '>' | (\d+) /;
camelia 「1234」
0 => 「1234」
timotimo no, $0 is the first one
oh, both get the 0 because of the alteration? 13:41

kawaii method extract-id(:$cmd-obj) { 13:46

moritz timotimo: yes 13:47
kawaii timotimo: my $user-id = self.extract-id(:$cmd-obj); unless $user-id ~~ / ^\d+$ / { return $user-id; }
this works :)
moritz m: say 'b' ~~ /(a)|(b)/; say $0
camelia 「b」
0 => 「b」
timotimo there's no actual need to have the '<@' '!' (\d+) '>' if you also have the (\d+) in there 13:48
and if you just want the string rather than the match, using .comb(/\d+/) is simpler 13:49

Kaiepi i ran into a confusing error while trying to write something a bit weird 15:02
so i have a Net::Telnet::Client and Net::Telnet::Server class, which both either use Net::Telnet::Terminal::UNIX or Net::Telnet::Terminal::Win32 depending on the os 15:03
the client and server are just unit classes, and the terminal modules look something like this hastebin.com/sivovafibe.php
but when i use them it claims merging global symbols failed because of a duplicate definition of Terminal 15:04
where is it getting that from? i checked with git grep and don't see anywhere where that should be happening
it throws the same error if i try to declare the classes in the terminal modules as Net::Telnet::Client::Terminal and Net::Telnet::Server::Terminal instead 15:05

guess i have to split the 2 modules into 4 15:33

albertferrico -bash: perl6: command not found 17:38
timotimo probably interesting to check "which perl6" and "perl6 -e '.say for $*REPO.repo-chain'
albertferrico so I guess I don't have it?

lembark Sanity check: If I wanted to keep POD in a separate file from the module, other than naming it FooBar.pod6 is there any convention for, say, recording it in the META6 or standard location (e.g., next to the module, in docs/FooBar)? 18:40
antoniog1miz assets
you can make an assets dir an specify the contents in the META6.json
lembark Thank you.
antoniog1miz github.com/JJ/p6-pod-load
in that module you can see an example
(it's not using assets but resources intstead) 18:41
lembark i.e., something like: 18:44
Uploaded file: uploads.kiwiirc.com/files/cd4177e6...pasted.txt
antoniog1miz mmm you can delete the lib line from resources 18:45
lembark Thought the "resources" => "whatever gets installed".
what's the dividing line between them? 18:46
antoniog1miz resources is everything you add to the module that "is not the module"
I dont know how to explain it correctly xd 18:47
lembark: what line?
lembark You just explained it correctly. 18:48
And succinctly :-)
antoniog1miz good then :)
Kaiepi is there a way to export a symbol from another module as the current module's own symbol? (like `export { default as Foo } from Bar` in es6) 18:50
i tried using sub EXPORT and using the module's name as the only key in the map returned but other modules can't find the symbol when i try to use it 18:51
antoniog1miz mmmmm, you can use unit class or unit grammar but I do not know with functions
Kaiepi wdym, like subclassing the other module? 18:52
antoniog1miz mmm nop, I said unit class to directly export the class, but I think that's not useful in your case 18:54
I suppose you have tried "is export"?
Kaiepi that wouldn't work for this, maybe i explained what i'm trying to do badly or something 18:57
this is what Net::Telnet::Terminal::Client looks like atm fpaste.scsys.co.uk/585188
18:58 empee0 joined
Kaiepi i'm trying to export either Net::Telnet::Terminal::UNIX::Client or Net::Telnet::Terminal::Win32::Client as Net::Telnet::Terminal::Client itself depending on the os 18:58
the module isn't entirely necessary, but it'd help make my code a bit cleaner 18:59
antoniog1miz ooh I see mmm 19:01
Kaiepi oh, maybe is export could work for this if i write `my constant Net::Telnet::Terminal::Client is export = require <...>` 19:02
...nope, can't use :: in a constant declaration 19:05
timotimo huh, i think this is the first time i hear about the assets thing for modules
antoniog1miz (assets is a dir I ussually use, resources is the good one) 19:06
timotimo oh 19:07
antoniog1miz at least that's what I normally see in the META6 modules
how would you do it instead?
timotimo i haven't a clue :)
antoniog1miz ah haha 19:10

timotimo weird 20:19
Kaiepi the problem was i got the name of the module i was requiring wrong, i forgot to rename it to Net::Telnet::Terminal::UNIX::Server from Net::Telnet::Terminal::ServerMaster 20:24
ugexe but that should result in a very explicit error 20:25
Kaiepi it should...
timotimo do we have a "local cache of ecosystem claims there is no such module available publically" output yet … 20:26
ugexe does zef have telemetry yet? no 20:27
timotimo how do you mean? 20:28
ugexe how else would you determine what modules an ecosystem does not contain that is being requested?
timotimo well, how does "zef list" give the names of all modules?
ugexe @json.map(*.<provides>.keys) or some such 20:29
timotimo JSON::Pointer:ver<1.0>
# JSON::Pointer
# JSON::Pointer::Relative
that could be enough of a hint, maybe
ugexe oh you want to take all given ecosystems, and then find dependencies that do not exist in those ecosystems? 20:30
i thought you meant a record of `zef install Doesnt::Exist`
Kaiepi btw the filename was right, just the module name in the unit class declaration was wrong 20:31

Does anyone around have Cairo installed? 21:21
timotimo most people with a linux system, i'm sure
thundergnat Well, I meant the Perl 6 port actually...
If so, what do you get if you grep /path-to-perl6-install/share/perl6/site/sources$ grep "unit module Cairo" * 21:23
For some reason, I have 24 installs on a clean build from scratch.
I wonder if that is why Cairo takes so long to install... 21:24
timotimo wouldn't you get one match per file in the cairo namespace? 21:25
oh, no, it's a single file
btw it turned out i didn't have it
thundergnat But they are all identical
It doesn't seem to be a problem really, I just thought it was weird. 21:26
timotimo oh haha
it installs one file per entry in the provides section
why are they there, that's weird
ugexe thundergnat: `zef list --installed` will tell you everything else installed 21:27
thundergnat timotimo, BTW any thoughts about getting nativecall pass structs by value working? I really miss not having SDL2_ttf :-( 21:28
timotimo oooh
ugexe seeing the list as words instead of sha1s might make it easier to remember what the are
timotimo jeez, that was a thing i was intending to do at some point
ugexe: i wonder, is Cairo the only module that has the same values for multiple keys in the provides section? we should be able to very easily query that, right?
also, i'm pretty sure that's not right 21:29
thundergnat I have a version of ttf working quite nicely locally, except for color handling :-(
ugexe that should be fine
although the way installation works it'll create X many copies of that same file, and precompile them all
timotimo froggs did it! 21:30
that commit is from 2015
it was "add provides section for latest panda (S11 support)"
you literally can't just "use Cairo", because that's not in there
ugexe its not wrong
timotimo well, it is now
it may not be wrong, but i do consider it nonsensical in this situation 21:31
ugexe yeah, there is no purpose in doing it this way in this case
it would be when doing -Ilib (not -I. or installed) and the import statement does `use Cario::Foo` before `use Cario` 21:32
all the tests just do `use Cario` so changing it should Just Work 21:34
then installation wont precompile lib/Cairo.pm6 23 times 21:35
timotimo thundergnat: good thing you stumbled upon that 21:40
thundergnat Yeah, Cairo has always been a real drag to install. No wonder if it is compiling it 24 times. 21:41
It was just an accident, I wanted to check something in the source of Cairo but didn't have connectivity so I grepped the sources folder for Cairo and got a whole page of identical entries. 21:44
and said to myself whut? 21:45

patrickb I have just successfully built and run a rakudo on Windows in "C:\data\p6-repos with spaces\rakudo". 21:51
ugexe in the old days before CURI multiple namespaces pointing to the same file didn't duplicate files 21:53
patrickb++ many have tried, one has finally succeeded 21:54
vrurg m: sub foo { my $a1; { my $a2; { OUTERS::.keys.say } } }; foo 22:01
camelia ($a2 $*DISPATCHER $_)
vrurg Isn't $a1 supposed to be in the list?
timotimo could be a bug in the keys method of the PseudoStash 22:02
there should also be a whole lot more in there i guess?
like all of the core setting
m: say OUTER::.keys
camelia ()
timotimo hm.
vrurg PseudoStash doesn't have keys. It just throws ctxlexpad or alike into Map's $!storage. 22:03
I just have discovered it by trying to get CORE:: hold all symbols from from all loaded COREs
timotimo oh
vrurg LEXICAL:: – apparently, same issue. 22:04
timotimo i guess that can't work, then :)
vrurg Is there a way to merge lexpads into a new one? 22:07
timotimo not to my knowledge 22:12

vrurg Ok, then iteration only. Thanks! 22:13
kawaii so, uh, I'm having a really strange issue, where perl is referring to a 'False' method that does not exist 22:16
Yet as you can see, there is no False method here, nor did I ask for one (github.com/shuppet/p6-api-discord/...annel.pm6) 22:17
timotimo m: sub test { return a => 1 }; say test 22:19
camelia a => 1
timotimo where is line 116 from Endpoints.pm6?
ugexe the line above it says "# TODO: I don't think we're handling a failure from this correctly"
kawaii timotimo: `my $val = reduce { $^a."$^b"() }, $r, |@f;` 22:20
timotimo are you sure that's correct? :)
kawaii ummmm, no :)
timotimo what's in $r and @f? 22:21
m: say reduce { say $^a, $^b; True }, 1, 2, 3, 4;
camelia 12
timotimo m: say reduce { say $^a, $^b; False }, 1, 2, 3, 4;
camelia 12
timotimo i assume you've got $r as a starting value and @f has a list of method names? 22:22
kawaii I didn't write large chunks of that library, so unsure
timotimo m: say reduce { say $^a, " ", $^b; $^a."$^b"() }, 1, "succ", "succ", "succ", "pred";
camelia 1 succ
2 succ
3 succ
4 pred
timotimo sounds like it should work, unless there's a False in that list :)
kawaii I'll get a local copy of the lib and add a say @f in there 22:23
ugexe m: say reduce { $^a."$^b"() }, (1); 22:24
camelia 1
timotimo we do have a CLI debugger that could help you here maybe :)
ugexe m: say reduce { $^a.""() }, (1);
camelia No such method '' for invocant of type 'Int'. Did you mean any of these?

in block <unit> at <tmp> line 1
ugexe seems like those should be the same 22:25
kawaii timotimo: so looks like you were right, but I don't know _why_ :) www.irccloud.com/pastebin/3UVPVgXu/
timotimo well, something undefined comes in there 22:30

kawaii timotimo: thanks for telling me about the cli debugger, very interesting output that shows me the internals of my app :) 22:36
22:37 netrino joined
timotimo that sounds vaguely like the debugger causing a big bad internal error :) :) 22:37
kawaii well, I see a lot of `+ Exception Thrown | Died` but since the app doesn't actually die when I see these I assume it refers to the methods themselves 22:38
timotimo wait, does my debugger cli do that? 22:39
kawaii www.irccloud.com/pastebin/2XHcP3bR/
timotimo: ^
22:39 nadim left
timotimo oh, that's not the debugger i was talking about lol 22:39
kawaii oh :(
but! that means you have a new toy to show me! 22:40
timotimo but if it helps, that's great
it'd be App::MoarVM::Debugger
you'll start a perl6 --debug-port=9999 --debug-suspend (if you want it to pause at the start) and then connect the moar-remote 9999 to it 22:47
22:48 natrys left 22:49 netrino left
vrurg timotimo: BTW, zef still can't install App::MoarVM::Debugger. ;) 22:50
kawaii `App::MoarVM::Debug` ;)
timotimo: thanks, I got it working, but I don't think it's going to give any information that is useful for _me_ :( 22:51
timotimo oh, is that it
kawaii: yeah, you'll have to have breakpoints in the right spot, then you can dig down into objects and such
