rypervenche So I've been working on moving my current Bash backup script over to Raku and adding some new features to it. I'm currently writing it as a single script and very functionally, but I was thinking of breaking it out into a real Raku module and not having it all cluttered in a single file. 00:53
I also have some resources (like my rsync exclude list and rsync options) that I think would make sense to have in separate files. Does anyone know of any good examples of a good module that I could use as an example? 00:54
Or any ideas of how I might break this up into different parts? I'm not sure if I would be wanting to make classes or simple keep it the way it is, but put parts into different files and simply call them in the main one: gist.github.com/rypervenche/b18cc7...9b479bfe03 00:55

Voldenet my approach might be wrong, because I'm a oop junkie, but I'd definitely make roles/classes out of this (so, for example mounts-file processor is a class, fsck accepts this class and so on) 01:30
and ofc, I'd get rid of anything that looks like global state, because I dislike having that - I'd rather have complex description of everything in my MAIN file, but again, it's only my preference 01:33

pilmihilmi I'm poking around in NQP and wanted to ask weather maybe the Precedence Parser of NQP can be implemented in Raku Grammar or weather the constructs used are NQP lowlevel specific? 08:54
I'm talking about this code: github.com/Raku/nqp/blob/master/sr...r.nqp#L384 08:55
moritz pilmihilmi: I don't think there's any magic in there that would prohibit a raku-level reimplementation 08:56
pilmihilmi: in fact, for my book I've implemented a simple precedence parser (only infixes, IIRC) in raku 08:59
(chapter "Case Studies" of www.apress.com/us/book/9781484232279) 09:01
pilmihilmi moritz: That sounds promising. But for instance cursor_start_cur() and $termcur.MATCH(), what type of raku grammar primitives could I use to implement these? The code also sets the pos of the match. I'm not really fluent in raku but it seems readonly property etc... 09:06
jnthn pilmihilmi: I don't think you'd want to translit it that directly; a bunch of what you see in there is optimization based on knowing internals. 09:09
When I've done OPP I've declared proto tokens for infix/prefix/postfix/term, written a rule like rule EXPR { <termish> [<infix> <termish>]* }, with token termish { <prefix>* <term> <postfix>* }, and then done the precedence sorting in an action method. 09:12
(My factoring was a bit different. In operators I did `make Foo::Infix::Add`, for example, and had a `prec` method on that class, for the precedence sorting, and then made a new instance of that type for the AST node in EXPR) 09:13
09:18 rbt left, rbt joined, vrurg joined 09:19 vrurg left, vrurg joined
pilmihilmi jnthn: moving precedence sorting to the action is a good hint. One thing I wonder still is weather the kind of dynamic parsing (try and backtrack like (I only sense it but am not really fluent in raku)) in the Precedence Parser of NQP is not really possible with raku? Is the NQP grammar exposing some internal/mechanisms that are closed in raku? It seems the "cursor" concept and calling "MATCH" seems NQP-only? 09:21
moritz pilmihilmi: an OPP shouldn't make the grammar backtrack 09:23
pilmihilmi jnthn: I'm trying to understand how the code is working because the grammar building on it is so exceptionally small and nice to read...
moritz pilmihilmi: I'd recommend you start with the examples in my book, they have a simple explanation using Raku code only 09:24
it only handles infixes, but contains some hints on how to expand it to other operator types and associativity and so on 09:25
jnthn pilmihilmi: MATCH is something that's called for you provided you're writing stuff as a token/rule rather; those calls are really it "pretending" to be the regex engine 'cus it's written out as a method
pilmihilmi moritz: Is Apress books distributed as pdf or do I need to intsall some proprietery program in linux? 09:30
moritz pilmihilmi: if you buy through apress, you get a watermarked (with your name) but DRM-free PDF 09:33
I believe you also get an .epub copy, but I'm not entirely certain

pilmihilmi moritz: currently stuck in payment limbo, but asking Stringer Customer Service now... 09:58
jnthn: May I aske weather there is some resources that describe the internals of the grammar system of raku, something like a raku-grammar-guts ? 10:00
jnthn I'm not aware of one. 10:04
(I figured it out by reading the implementation. Or perhaps by writing a few parts of it. :)) 10:06

[Coke] did a git pull --rebase, reconfig/build, still getting /Volumes/BUKKIT/Users/coke/p6/bin/nqp-m version 2020.06-9-gdb0c1088f is outdated, 2020.06-19-g3e928af0b expected. 14:24

[Coke] (using the installed version and not the version we're currently building) 14:24
14:24 patrickb left 14:26 fling left
patrickb71 Coke, do you build nqp yourself or do you let the rakudo Configure.pl script do that for you? 14:27
[Coke] I let config.pl do it 14:28
I just did an rm ./nqp and am trying again, JIC
(if this works, guessing we need to update the NQP revision ref.) 14:29
(I also tend to include --force-rebuild)
14:31 sena_kun joined
patrickb71 Coke: I'm not entirely sure how exactly you do the build. Given you already had rakudo and nqp installed and then try to rebuild rakudo (irrespective of you deleting the `rakudo/nqp` folder) and *not* passing the `--gen-nqp` option is expected to result in the error you posted. 14:31
[Coke] /opt/local/bin/perl5.28 Configure.pl "--prefix=/Volumes/BUKKIT/Users/coke/p6/" "--gen-nqp" "--gen-moar" "--backend=moar" "--moar-option=--debug" "--force-rebuild" "--force-rebuild" $* 14:32
running that inside a long standing 'rakudo' clone. 14:33
patrickb71 Hm. I think that should work.
[Coke] (not sure why --force-rebuild is in there 2x)
looks like removing the nqp folder fixed it - guessing that we're missing an nqp commit that addressed something? 14:34
holyghost [Cokde] : you better build it cleanly if you can
[Coke] Yes, as I said, removing the nqp folder (which forces it to latest) avoided the issue. 14:36
14:37 sena_kun left
vrurg [Coke]: --force-build is there because this is what you used last time when ran Config.pl 14:38
[Coke] yes, didn't realize it wasn't de-duping. 14:39
patrickb71 vrurg: github.com/rakudo/rakudo/blob/mast...do.pm#L664 14:40
Does that line mean that once an nqp is checked out it won't change the checked out version?
[Coke] oh, that makes it look like force-rebuild is having kind of the opposite effect of what I expected.
[Coke] drops it from his default build. 14:42
holyghost good point 14:43
vrurg patrickb71: only when --force-rebuild is used. Because the option is mostly for development when one needs to test the exact combination of commits. 14:45
patrickb71 OK. Then it's clear why it behaved the way it did. 14:46
[Coke] Might be nice to change the force-rebuild help to indicate that (test currently checked out versions) as opposed to the negative phrasing currently there. 14:47
Thanks for the explanation, though, much clearer now

codesections are any `$=` variables other than `$=pod` currently implemented? I get `pod variable $=Foo not yet implemented. Sorry` when attempting to access any others, as described in the docs ( docs.raku.org/language/variables#The_=_twigil ) 15:36

codesections :guifa Thanks. I'm hoping to be able to help with that work, though I probably need to learn a bit more about Raku and a lot more about Rakudo & NQP) before I can be of much help 16:12
guifa Yeah, I think we’ve hit the point where people are starting to look at long-term stuff more and more — where in-code documentation plays a huge role — and so the same usability kinks/quirks that early Raku went through we now to get to go through :-) 16:16
codesections :guifa "we’ve hit the point where people are starting to look at long-term stuff more and more"… unlike the last 20 years of Raku's development as a 100-year language, where everyone was focused on the short-term stuff :D 16:21
guifa haha
I meant long-term coding projects
As opposed to short-lived scripts / etc
codesections yeah, and it's a fair enough point. Just struck me as funny :) 16:22
16:23 Tirifto joined 16:24 Altai-man_ left
guifa Lately I’ve been playing around with doing more and more literate styles of documentation 16:26
16:26 wamba left
codesections Yeah, Pod6 really seems like it'd be a great fit for that style 16:26
guifa Which of course is what I feel like pod most lends itself towards, but I also wonder then how the bestw ays of presenting that on a user-facing side. I’m sure for comma it could have an code-“reading” style where the pod is rendered appropriately without the code, but it’s the creation of, e.g., a website documenting things that makes me most think about stuff 16:28
JJMerelo guifa: cool! 16:30
16:30 vrurg joined
guifa that’s why a link to a code object (me and ShimmerFairy were talking about it the other day) would be awesome, because right now, all of the awesome rakudocs are entirely separate from the code (speaking of, jjmerelo++) in order to enable the links 16:33
codesections Yeah, I've been thinking along vaguely similar lines. In my ideal world, `#|` declarator blocks could be used to extract more API-level docs, while the main Pod blocks could give a more "literate" feel for the code. And both could be automatically viewable online as HTML or locally (via man? info? as plain text?). But that's getting pretty far ahead 16:34
16:34 hungryd76 left
JJMerelo That's cool 16:35
codesections (Poking around with these sorts of ideas was what led me to realize that `#|` can't currently be used to document variables. But I opened an issue: github.com/rakudo/rakudo/issues/3804 16:36
)
JJMerelo For the time being, you need to explicitly mix code and documentation. doc renderers just extract the declaration part...
SmokeMachine kawaii: how can I help you? 16:37
JJMerelo codesections could you also please show the AST for that piece of code? I don't remember exactly how to do that, it's something like raku --ASt
Let me check
kawaii SmokeMachine: If I want to create a table with a combined primary key in Postgres, can I just use `is serial` on two items instead of `is column`? :) 16:38
16:39 dolmen left
JJMerelo codesections no, raku --target=optimize docs.raku.org/language/faq#Is_ther...f_the_AST? 16:39
SmokeMachine kawaii: yes, but `is serial` mean id + auto-increment, you probably want 2 `is id` instead
JJMerelo So you save your program to a file, and run that through raku --target=optimize, and it prints the AST so that we know why the pod is not assigned to the right declaration. 16:40
kawaii SmokeMachine: ah yes, I understand, I will try that now, thanks :)
SmokeMachine kawaii: like here: github.com/FCO/Red/blob/master/doc...rimary-key
16:40 dakkar left
codesections JJMerelo: Aha, I didn't understand what you were asking for. Will do! 16:41
kawaii SmokeMachine: I missed that, there is so much Red documentation it's hard to find specific things :)
JJMerelo codesections comments (and then pod6 sections) are part of the AST, so what way we know where they are and check if there's an arror
you can also use target=ast
SmokeMachine kawaii: that page is new... I really need some help to organise the documentation... 16:42
kawaii SmokeMachine: instead of using `has DateTime`, what can I use to get `timestamptz`, which is postgres-specific 'timestamp WITH timezone'? :)
SmokeMachine kawaii: you can use `is column{ :type<timestamptz> }` if I'm not remembering it wrong... let me take a look 16:43
16:44 defaultxr left, defaultxr joined 16:45 defaultxr left, defaultxr joined
kawaii SmokeMachine: I'll try like this `as DateTime $.last-updated is column{ :type<timestamptz> }` :) 16:45
16:46 JJMerelo left
SmokeMachine kawaii: yes, it should work... if it doesn't, please let me know 16:47
kawaii SmokeMachine: I think this error is unrelated, but I'm new to the lib and unsure :) www.irccloud.com/pastebin/6gtCMxno/
16:48 wamba joined
kawaii L17 is `Reputation.^create-table: :if-not-exists;` 16:48
SmokeMachine kawaii: sorry... I'll have to add that...
kawaii SmokeMachine: otherwise my script works fine if I just use the regular DateTime :) thanks for your help! 16:50
SmokeMachine: I note that Red has created column names using _ instead of - (which is totally fine in postgres if you wrap it in quotes i.e. `"user-id"`) is there a way to override this behaviour yet? :) 16:52
16:52 ufobat left
SmokeMachine kawaii: it seems I've forgot the default... :) 16:54
fixing it...
kawaii: not yet... 16:55
kawaii SmokeMachine: great, I'm going afk for 1hr or so, but feel free to ping me if there is stuff to test :)
I really love Red so far, even from making my first table :D

melezhik Hi! Does rakudo work on Mac OS? 17:19
lizmat melezhik: yes 17:20
melezhik what is the best way to install Rakudo on Mac?
lizmat I have no idea, I do a git clone and then build
but then again, I also have XCode installed
melezhik yeah, is it possible install with user, without root access?
providing that xcode is here 17:21
lizmat works for me :-)
guifa Building from source is also probably best right now. Current versions of macOS are starting to get insane about permissions for running non-code-signed software

Zero_Dogg How does rakudo-js actually work? Is it a transpiler or does it actually bundle an asm.js or similar build of rakudo? 17:33
kawaii SmokeMachine: tested, working, thank you so much! 17:36
[Coke] rakudo targets nqp - rakudo.js has a JS backend for NQP 17:37
17:37 Xliff left
[Coke] easiest way to use it is to install the NPM package. 17:37
SmokeMachine kawaii: \o/ 17:38
kawaii: would you mind to do me a favor?
kawaii SmokeMachine: I can certainly try? :) 17:39
holyghost js is cool
SmokeMachine kawaii: could you, please, create an issue to make it possible to change the table name?
[Coke] er, phrasing was weird there: NQP has a JS backend. (it also has a moarvm backend - the default, and a jvm backend)
kawaii SmokeMachine: I was just about to ask if you'd like me to do that :)
SmokeMachine kawaii: I mean a way to set the rule for the table name creation 17:40

emoji annotations or spelled-out numbers
Altreus apparently "The use of `.result` in a `whenever` block is blocking." ... I assume this applies to `await` as well. Given that, how do I ensure I inspect the result of a promise (in order to get any errors) but without blocking the whenever? 20:59
or the react
holyghost guifa : SFY 21:00
Altreus oh do I just do whenever $promise inside the existing whenever?
Asking questions is a great way to suddenly realise the answer!
Altai-man_ Altreus, if you want to inspect result of a promise _eventually_, use .then.
If you are working with react|supply whenever -> yes, can just add another one on top. 21:01
lizmat Altreus: I'd say that's it, yes
Altreus okay, and what if I don't want to do anything on success? Is it bad form to have an empty whenever?
If I use the then form I have to get its result so at least there's something in it, but it seems unnecessary just to have words in the block 21:03
Altai-man_ lizmat, very cool weekly! Out of curiosity, no release mention? I kinda thought you kept it back a bit to add that.
lizmat no, I kept it back to get the election announcement in, because I was working on that as well at the same time 21:04
Altai-man_ I see, okie.
lizmat next week a proper announcement in RWN, with maybe a R* as well :-)
Altai-man_ While releasing I thought with me on board we probably had more "a week after" announcements than "in time" ones, so maybe people are used to it anyway. :> 21:05
lizmat in any case, now that the release is out again, I will be committing to master again :-)
Altai-man_ lizmat, please do! Also PR queue is growing and all that.

jnthn Altreus: Yes, if you're using the subscription to prevent termination of the enclosing `supply` or `react` for some reason, for example 22:24
SmokeMachine: A role declaration evaluates to the parametric role itself, but the name is a role group (for all roles with the same shortname); it's like a proto with multi candidates. 22:26
SmokeMachine: Also, .^add_method ao a composed role is risky in that roles are immutable (not to mention you won't get to close over the type variables)

cpan-raku New module released to CPAN! JSON::Fast (0.13) by 03TIMOTIMO
timotimo ^- welcome to fast-town 22:35
jnthn SmokeMachine: What's your use case btw? I may be able to suggest something
SmokeMachine I'm adding a experimental code on Red. 22:36
like this: github.com/FCO/Red/blob/master/lib/Red.pm6#L47
but I have 3 classes that does a role that has methods that if it .^can a method, it does the experimental feature, otherwise it does the original feature 22:38
jnthn: ^ 22:39
jnthn Ah, but there' you're adding a role to a class, not a method to a role?
SmokeMachine on the new feature I'm working on it is a method on a role... 22:40
timotimo i imagine you can put a ^parameterize method somewhere that might add an extra role with that experimental feature in it
SmokeMachine www.irccloud.com/pastebin/jFOdWv8s/jnthn%3A
jnthn Yes, but even if you add a method to the role, it's absolutely not gonig to be propagated to any class that has already composed the role 22:41
That's what I meant by roles being immutable. 22:42
SmokeMachine yes, I got it... 22:43
any suggestion of hoe doing that?
www.irccloud.com/pastebin/odKB22Rz...20is%2Fwas
jnthn I wish I had ideas in spades, but alas... 22:44
I guess the problem is about the scope of this too
Is `experimental` meant to make these effects global? 22:45
SmokeMachine yes
at least for now
another option I thought was: if its using experimental, uses one role, and use a different role otherwise 22:46
jnthn Dunno, do you know all the classes that do the role? If so just add it to each of them. I mean, experimental things either go away or become none-experimental, so maybe beauty doesn't matter
That or just have a package Red::Experimental and set $Red::Experimental::Feature = True; or some such and then check the variable
SmokeMachine that makes sense... 22:47
jnthn Not everything has to be done with types :)
SmokeMachine and I have a list of all types... I can grep which uses that role...

SmokeMachine jnthn: ended up with: github.com/FCO/Red/blob/master/lib/Red.pm6#L48 23:21

SmokeMachine sure!
(but seems to be working...) 23:24
