Xliff tonyo: I was just hoping for a more direct method than" ::?CLASS.^attributes.grep( *.name eq $attribute-name )" is all. Thanks for the help. 00:09

tonyo Attr table, nice find 00:23
Xliff Thanks! I think that will work. 00:26
Thanks again for the help, tonyo++
00:26 Kaiepi left
Xliff In the end, this is what worked... 00:27
m: class A { has $!x; has $!y; method a { self.^attribute_table{ $!x.VAR.name }.gist.say }; }; A.new.a
camelia Mu $!x
Xliff tonyo: You mentioned a use case. Well, in some of my code, I have postdeclared comments on attributes that serve as annotations. Such things I can use at runtime. 00:28
So direct access to the Attribute (not its value) is preferred. This solves that problem.
tonyo Ahh v nice

tbrowder hi, need some help about module organization for a class and a separate file for a r 13:05
*set of subroutines for use by it and other progs 13:06
call the class Bar in dir lib/Foo 13:07
call the file of subs lib/Foo/Subs.rakumod 13:08
i want to call a sub in Subs from class Foo::Bar 13:09
no reply yet, please, i need to check some more...i'm getting circular call errors but i haven't given just yet. 13:13
13:22 mahafyi joined
ugexe do you know what a circular reference is? 13:25
if you have Foo.rakumod and Foo/Subs.rakumod and each one of those files uses the other file, its a circular reference 13:26
because when you load Foo it then goes to load Foo::Subs, which then needs to load Foo which needs to load Foo::Subs, and so on 13:27
it sounds like you need to move code in Foo::Subs (the code that depends on Foo in such a way you need a `use Foo` in Foo/Subs.rakumod) to a third module 13:28
or put that logic inside of Foo::Subs in such a way that it doesnt need `use Foo`

[Coke] if we don't have that in one of the tutorials on the doc site, someone please open a ticket for it. 14:39

Anton Antonov @Coke In case you did not get the message -- you have issues. 14:40

Anton Antonov @El_Che Thanks! 15:48
All the chapters of my PhD thesis start with epigraphs that are quotes from "The Offspring" songs. 15:49
nine Anton Antonov: that's epic :)
El_Che Anton: as everyone's should! 15:50
Nemokosch not sure if it's possible to forgive them for that awful Obladi Oblada parody... but anyway, that's not what I wanted to say 16:11
do we have something like Text::Extract::Word in Perl, or is it up to the new generation?
"the new generation" that hopefully won't need much of .doc files but unfortunately I do

ToddAndMargo I have created a class and  a variable of that class.  I have been using "push" to create an array of that variable.  Problem: all of the lines inside the array (about 20 of them)  are all the last line I pushed into the array,  Am I doing something wrong?   The offending line is 84: "push @Tasks, $TaskLine;" 20:31
vpaste.net/iI8EM#uploads
lizmat could you create a gist with line numbers ? 20:33
ToddAndMargo Windows 11; raku -v 20:34
Welcome to Rakudoőď√§√≥ v2022.07.
Implementing the Raku‚Ē¨¬ę Programming Language v6.d.
Built on MoarVM version 2022.07.
lizmat looks like you're only creating a single $TaskLine object
and updating that in each iteration and pushing that 20:35
instead of creating a new TaskLine object each iteration
ToddAndMargo It is that last line repeated over and over 20:36
Xliff ToddAndMargo, under "for $RtnStr.lines[ 3..*-1 ] -> $Line {" 20:37
You need a "$TaskLine = TaskLine.new"
Rather ... "$TaskLine = TaskLineClass.new" 20:38
You can turn the "my $TaskLine = TaskLineClass.new" above that into just "my $TaskLine" 20:39
ToddAndMargo I though I was just reusing line 51 "my $TaskLine     = TaskLineClass.new;"
Xliff Nope.
Well... yes. You are.
That's why you are getting the repeats. 20:40
'You are using the same object. Not a new one.
So when you go to print the list in the next loop, they are all the same.
It's pretty much as lizmat++ said.
ToddAndMargo Fixed! Thank you! 20:42
   for $RtnStr.lines[ 3..*-1 ] -> $Line  { 20:43
      # print "$Line\n";
      my $TaskLine = TaskLineClass.new;
      $TaskLine.ImageName     = $Line.substr(  0..24 ).trim;
      $TaskLine.PID           = $Line.substr( 26..33 ).trim.Int;
      $TaskLine.SessionName   = $Line.substr( 35..50 ).trim;
      $TaskLine.SessionNumber = $Line.substr( 52..62 ).trim.Int;
      $TaskLine.MemUsage      = $Line.substr( 64..75 ).trim;
      push @Tasks, $TaskLine;
Xliff yw - And try to minimize posting code like that in IRC>
I speak from experience! You get yelled at!
Particularly if you bother camelia. 20:44
Xliff flees
ToddAndMargo oops!
lizmat also: if you want to ensure types and values, you'd probably be better of in a TWEAK method doing all of the cleanup
*off
ToddAndMargo Soon as I learned Raku's OOP, I dropped hashes.  OOP is just to powerful and easy to read 20:50
Xliff ToddAndMargo: Yes. However hashes still have their place. ;)

Xliff Oh god bless Raku for case sensitive method names!
21:32 Maylay left
lizmat although, you could actually make method lookup case-insensitive if you really wanted :-) 21:33
by replacing the ^find_method method in the meta-class :-)
21:34 Maylay joined
Xliff lizmat: Yes, I do realize that. I'm good. Thanks! ;) 21:40
lizmat hehe 21:41
Xliff Case sensitivity solves a significant design issue in my code.
So I'm happy about it.
