tbrowder hi, gang 14:03
if i have a class instance, how do i make it take certain actions if the caller exits the program prematurely? i am used to using the END block for non-class things, but i'm sure there are other considerations for a class instance. 14:07
the main action i'm thinking about is saving the current open file content, closing that file, and reporting status to stdout. 14:10
the class has an attribute for the open file handle and name. 14:11
14:39 dmc7z joined
guifa2 You can get the END phaser to work on a class level, but not on an instance level AFAIK 14:40
theoretically you have method DESTROY, but there's no guarantee that will be called
moritz yes, you'd have to do some magic to keep a list of all open instances 14:41
and then in the END phaser, close them all
XOR require your caller to call a .close or .finish method or so on each instance, and make it the caller's responsiblity
and then the caller can do something like my $instance = YourClass.new() will leave { $instance.close } # or however the "will" trait works 14:42
docs.raku.org/language/phasers#ind...will_trait
guifa2 this is probably the easiest, TBH: tio.run/##TY5BCsJADEX3c4pPcSldumgR...GHp3IZ0Yfw 14:43
And then add another method, if necessary, to remove stuff from thel ist as needed
dakkar one problem I see with that, is that all the instances will be kept alive throughout the life of the process… 14:44
(one of the few times where perl's weak refs are very useful) 14:45

dakkar notice that each END in the source code gets installed / executed exactly once 14:57
guifa2 dakkar: indeed, that's what I meant to remove stuff from the list as available. Could probably fairly easily make a "register" and "deregister" class method that the instances call

RaycatWhoDat jmerelo: Gotcha. 16:46
tbrowder oops, END in TWEAK fires even though no class object exists! and i get an exception for attempting a method on a null object. 16:56
trying a "tweak"... 16:57
RaycatWhoDat How do you specify a sequence with a constraint? 16:59
Something like 1, 1, * + * ... * where * is less than 13 17:00
Seems like I'm just getting (Nil)s
tbrowder i fixed it (so far) with "END { if self { self.meth }}" 17:01

pilne so, i'm loving the zip download with the set-env.bat file, it's great for learning with raku wherever i can take my USB stick, i've just got a quick question about where zef will install modules to by default with that setup, will it dump them in the extracted file structure somewhere (good) or in userspace somewhere(bad)? thanks in advance! 19:37

20:25 tejr joined
tony-o you can also just dump $*REPO.repo-chain and look for the one that says `site` 20:26
guifa2: i'm not opposed to it just for posterity - people using older versions of zef would benefit from them being on p6c but ultimately i'd like to see p6c deprecate 20:27
guifa2 tony-o: yeah, agreed on wanting to se p6c fall to the wayside. I've been aiming (since we're early in adoption right now) only about a year's worth of deprecation before tossing stuff in my modules. 20:30
In this case, I feel like the best practice would be for my extant modules to stay on p6c for about a year after 6.e, when presumably most people would starting getting fresh installs of Raku with an updated zef.
tony-o agreed, there's a ton of cruft in p6c that will likely clean itself up by way of deprecation 20:54
going through it i think there are still modules without author/version/etc 20:55
is there someone available who knows more about modules.raku.org's internals that can test this branch? github.com/Raku/modules.raku.org/tree/zef-eco - this should put zef-eco on the modules.raku.org page 20:56
tbrowder tony-o: when you refer to modules w/o author info, etc., are you talking about those adverbs being in the module? 21:00
tony-o in the META
they're just basic {"name": "XY::Z", "description": "test"} 21:01
tbrowder if so, that’s one of the reason’s i’ve come to love mi6
ok, meta, got it. another thing i’ve been voting for: some minimal and testable standards for acceptable modules. 21:03
before they can be accepted as “official” in the modules.raku.org. 21:05
tony-o digging through modules.raku.org, i'm kind of liking the raku code for raku.land 21:06

guifa2 tbrowder: I had mention to lizmat that I've thought about also creating a curated list of modules — not in an ecosystem per se, but just a website that might be more purpose driven than name driven (e.g. "modules for handle XML", and a list of each of those with the differences — bindings to native libs, pure raku, performance, etc— or similarities — compatible APIs— being discussed). 21:45

Then return that hash at the end. 23:42
23:43 MasterDuke left 23:45 mowcat left
guifa2 So you can do that — but make sure there's no way your regex can backtrack, or you might end up pushing multiple times for the same value (I maaaaaaybe made that mistake once back in the day haha) 23:48
in the TOP rule, define a dynamic variable
and 'make' it at the end 23:49
rule TOP { :my %*result; ^^ ('-' <flag-with-values>)+ %% <.ws> $$ { make %*result } }
in your flag-with-values token, after you've matched everything, you can insert a small code block to assign to that hash, e.g. 23:50
token flag-with-values { <flag-name> <.ws> <flag-value> { %*result{~$<flag-name>} = ~$<flag-value> } } 23:51
Then just do your parsing, %options := OptionsParser.parse( $string ).made 23:52
RaycatWhoDat What's that `:my` syntax? 23:54
guifa2 that's how you declare a new variable in a regex scope
RaycatWhoDat Oh neat
guifa2 code blocks are their own local scopes inside of regex
RaycatWhoDat and the `~$<...>`? 23:56
