tbrowder hi, all 11:44
anyone wanna discuss class DateTime ? 11:45
i'm trying to understand class Instant. docs say it is not tied to any epoch, but that doesn't make sense to me. 11:46
what does a zero Instant mean? 11:47
one can convert a posix timestamp to either an Instant or a DateTime object and either object will then show the same Instant value. 11:48
also, docs don't say it but you can create a new DateTime obj from a fractional posix timestamp and the new obj will show fractional seconds (but only the integral part of the posix input). 11:52
that sounds like a bug to me
11:54 judd7 left
gfldex tbrowder: "not tied to any epoch" means: "Don't assume the unix epoc. In fact, don't assume anything." 12:05
PimDaniel o/ 12:08
tellable6 2021-03-31T20:00:09Z #raku <ggoebel> PimDaniel: yes it looks like you can set breakpoints and debug step by step in the community editions
12:08 judd7 joined
PimDaniel ggoebel ok thank's! 12:09
tbrowder but the docs should say a bit more than that, don't you think? at least say in general how the number is derived.
PimDaniel Is this ugly: my @all_lines := (@!diagonales,@vertices,@mis_lines).flat? Could we write this more simple? 12:11
I mean is there a simpler way to cat some list without using flat? 12:12
12:13 wamba joined
tbrowder surely there is a common zero, otherwise how could two Instants be compared? 12:13
so if there is a common zero on the same time scale, mustn't that zero be an epoch, even if it doesnt't have a commonly known name? 12:15

gfldex tbrowder: The common 0 is an implementation detail (that is not marked as such). 12:53
tbrowder fair enough, but i have glanced at the code and see reference to 'tai' and that name rings a bell. 12:56
ah, International Atomic Time (TAI), abbr from the French name 12:57
gfldex how about `my **@a = @b, @c, @d` ? 13:09
13:10 monkey__ joined
gfldex m: my @a = <a b c>; my @b = 1,2,3; for @a, @b -> **@c { dd @c; } 13:11
camelia Array element = [["a", "b", "c"],]
Array element = [[1, 2, 3],]
gfldex not quite DWIM
vrurg gfldex: why? It is expected. 13:17
for doesn't flatten, ** is explicitly non-flattening. 13:18
gfldex m: my @a = <a b c>; my @b = 1,2,3; my @c := -> *@c { @c }(@a, @b); dd @c; 13:25
camelia Array element = ["a", "b", "c", 1, 2, 3]
gfldex My point is that signatures can autoflatten but assignment can't. That's a little odd.
13:35 berber44 joined
vrurg As to the original PimDaniel question I'd say | is the best answer. But otherwise it's an interesting point. I wouldn't expect `*@a = ...` to work as there are possible side effects. But for `my` it would be an interesting point. 13:47

PimDaniel Well this is not clear to me since i've go many answers : Has i undestood, i tried : my @combined = (|@a,|@b,|@c,...) and it works too. But for now i do not mind to keep .flat. 14:07

ggoebel a comma ide question... trying to stub out a new module. created a t/00-sanity.rakutest file with the contents: use v6.d; use Test; use-ok 'MyModule:ver<0.1.0>'; done-testing; -And Comma's code analysis is complaining that use-ok and done-testing subroutines are not declared. I.e. it isn't picking up on their being exported by Test. Are these false-positives a known issue? Is there a fix or work-around? 15:21
jmerelo ggoebel: can you post the code? 15:22
ggoebel: and the error message?
Ah, OK, that's all the code there is...
ggoebel: it might be the case that they're not "picking them up" since they are system libraries. Just add them to the META6.json file 15:23
ggoebel will give that a try 15:24
jmerelo ggoebel: It won't hurt, and will help comma find them and not complain about them.
ggoebel add Test, Test::META, and App::Prove6 to test-depends... no luck. The code analysis which runs before my initial git commit still shows the same "Error:(4,1) Subroutine use-ok is not declared" and similar for other Test imports. 15:28
guess I can tick the box to turn off code analysis on git commits
sena_kun ggoebel, can you check in Project Structure what SDK is set? 15:31
ggoebel, File -> Project Structure.
15:33 fluca1978 left
ggoebel <No Project SDK> which if I read correctly should default to what it finds in the PATH... Raku v2021.03.22.gec.73.d.6.c.96 15:33
setting that explicitly, closing, and reopening project still results in same error in code analysis 15:34
15:37 andinus joined 15:38 Doc_Holliwood left
jmerelo ggoebel: actually, you have to set that up explicitly for every project 15:42
15:42 jmerelo left
ggoebel Interesting. Just updated comma to latest available community edition. pretty sure it said if it wasn't set it would default to first raku found in path. but now that I've set it, I can't unset it. 15:45
s/just/I had just/
sena_kun ggoebel, I think you misread the changelog about using the default. As for the symbols not found: the indexing is done? Can you do some typing in the file to re-trigger analysis? 15:53
15:55 rindolf left
sena_kun I cannot reproduce it, can you compare what you are seeing: ibb.co/mhTNLgJ ? 15:57
16:01 mowcat joined 16:02 RC left
ggoebel here is what I get before renaming files from *.t to *.rakutest 16:02
ibb.co/cy6cyqP
sena_kun ggoebel, are you using some plugins? Maybe like Perl5 support plugin? 16:03
16:04 kurahaupo joined
sena_kun It appears to me that this is likely true and given Perl 5 and Perl 6 shared `.t` extension for test files in past the Perl plugin is likely to take the control and thus Comma plays no role with it. But it will be better with using a non-ambiguous extension, *.rakutest as you noted. 16:05
ggoebel And here after .pm6->.rakumod and .t->.rakutest 16:07
ibb.co/xjcb4Cr
sena_kun ggoebel, can you please do File -> Invalidate Caches and restart? 16:08
ggoebel no change 16:13
actually my bad... or color blindness... either that or turning off the perl6 plugin worked 16:16
thank you for your help!
sena_kun ggoebel, you mean perl 5 plugin? Glad it worked for you. I still think having Perl 5 plugin enabled should not do such hindrances, so I'll try to investigate it some time. 16:18
ggoebel yes sorry perl5 plugin
still works after turning perl5 plugin back on 16:20
In the future, I will remember to try File -> Invalidate Caches and restart 16:21
do you know what all gets cached?
there were enough project configuration variables that I'm not sure which one created the original problem 16:22
sena_kun ggoebel, I would bet on 1)Perl plugin "overloaded" .t files, so they were not processed as Raku ones; 2)No SDK set in Project Structure, which is mandatory; When you fixed two of these and restarted it once or twice it started to work. 16:23
ggoebel I appreciate you taking the time to help me. Thank you! 16:24
sena_kun ggoebel, no problem, you are welcome!
jdv79 codesections: peeked at the MAIN issue a bit more - looks like all the binding machinery in bootstrap might be needed to do it correctly - oof. hopefully there's an easier and still correct way. 16:29
16:37 kleb joined, MilkmanDan joined
kleb hi folks! i have a project where i am using raku as a basic, project localized, code snippet transpiler from c++ to rust -- i have a performace problem with my codebase and i am wondering if somebody here might know something which will help me! 16:38
basically, the structure is as follows:
the main project lives in src/, while the raku stuff lives in u/ 16:39
16:39 guifa2 joined
kleb we have u/{grammar,util,x1,x2,x3,x4,x5,x6,x7,...}.rakumod 16:39
where the x1.rakumod, x2.rakumod, etc all hold functions which take the parsed IR and turn it into text (they are essentially output functions) 16:40
grammar holds the full grammar required for all my parsing needs
util holds all the utility functions, used by the x1,x2,x3, etc so i dont have code duplication 16:41
there is also u/translate, which is my entrypoint, and u/typemap.rakumod, which is the file i am having problems with
basically, what typemap.rakumod is, is a running hash mapping c++ type names (many local to the project itself) to rust type names 16:42
when i say "running hash" what i really mean is that i continuously update it as i encounter new types (during the porting process)
16:43 sno left
kleb as far as code correctness goes, i know my algorithms are all working, for the most part.  the grammar is correct enough and fast, the utility functions do what i need them to do 16:43
however
util.rakumod relies on typemap.rakumod, because at several points in the utility functions, we need to convert from one type system to the other
each of the x1, x2, x3, etc rely on util.rakumod 16:44
and u/translate relies on each of the x1,x2,x3,etc
u/translate also relies on the grammar, and util
so it is basically a diamond (perhaps unfortunately 16:45
)
jdv79 what exactly is the perf issue? you seem to have just said a bunch about not that. 16:46
kleb the problem is that as it is currently structured, every time i update typemap.rakumod, the whole thing needs to recompile -- for some reason, that is taking sometimes a minute or two 16:47
jdv79 you could try the profiler though last i tried once the code involved gets trivially large it craps out
kleb in my use case, this file typemap.rakumod is basically continually being updated
it actually seems to start with util.rakumod -- any time util.rakumod changes, i need to do a big recompile 16:48
everytime one of the x_i change, or the grammar change, or the toplevel translate entrypoint change, it actually doesnt cause such a  long compile cycle 16:49
just a few seconds
jdv79 well, precomp is based on the dep chain afaik - maybe try to organize so the changes so less of a chain's length...
i think there's an env var that might help illuminate some of that stuff - can't remember... 16:50
kleb thats what it seems like to me, too
the issue i think is that something which needs to be closest to the surface is the deepest
namely the typemap
i tried doing "require" instead of "use" but that hasnt seemed to work
the positive is that once it compiles once, it goes fast every time (as long as i dont trigger a recompile by editing typemap) 16:51
is there a way for me to instruct util to use the %typemap hash passed in somehow at runtime? 16:52
so that changes to the typemap.rakumod source file dont trigger a recompile?
or to *pass* typemap into util.rakumod as a whole somehow? 16:55
so that way i dont need to use u::typemap; at the top of util.rakumod 16:56
i considered changing every single function call in util.rakumod to take %typemap as a parameter, then just pass it in from the toplevel 16:57
but that seems somehow like a much inferior solution -- far too much visual noise and added complexity 16:58
i basically need to instruct util.rakumod to "use %typemap, but dont try to compile against it or worry what's in it.  just know about it.  it will be there (somehow) when you need it"
jdv79 require will still factor into precomp, right? maybe a deferred require could help. 16:59
i've done stuff like this in Perl but not Raku so i'm not sure...
kleb ^thats what it seems like is happening 17:00
i just tried it a few seconds ago
without compiling, the program takes 1-2 seconds
but then, if i update one line of the typemap hash, it takes roughly 55 seconds
jdv79 yeah, compiling is still very slow cause regexes are still very slow:( 17:01
maybe some day precomp won't be such a crutch and complication
kleb exactly -- even though i am just updating a hash, there are regexes all over util.rakumod and grammar.rakumod
the issue is that these regexes are all recompiling as well when i trigger the update by updating a simple hashmap 17:02
the hash is just strings to strings, nothing complex in it
jdv79 i mean the raku compiler uses grammars to parse the raku code and that's a large part of why rakudo compilation is slow;)
kleb understood 17:04
it seems tricky to parse without the parsing tools it provides :)
what is the "deferred require" you mentioned 17:05
it seems like i may as well bite the bullet and pass %typemap into everything 17:06
although, it seems likely that there is a workaround
sena_kun kleb, if you don't want to pass something as an argument, maybe dynamic variables can be useful? 17:07
jdv79 odd that RAKUDO_LOG_PRECOMP seems to not work... 17:08
RAKUDO_MODULE_DEBUG may be of use though 17:09
kleb ah, dynamic variables -- i have not tried or needed these before 17:10
i will read to see if i can use 17:11
how do they work with nested scopes? 17:12
lizmat m: sub a() { say $*FOO }; my $*FOO = 42; a
camelia 42
lizmat m: sub a() { say $*FOO }; { my $*FOO = 42; a }

smolck Hello! So, I'm new to Raku, and quite intrigued by it so far; specifically, I'm interested in the JVM backend of Rakudo. There don't appear to be many examples of its usage as far as I've found (although if there are and I just missed them, I'd be happy to go read them given a link or links), and so I have some questions about it, the main one 20:28
being about interop. I know that it's possible to call Java functions, but I haven't seen anything about subclassing Java classes/interfaces/etc. Is that currently possible (and if not, will it be in the future), and if so, might I ask how it's done?

vpcc42 Hi. Can somebody recommend me a good IDE or editor for raku? I've tried Comma / Intellij plugin, vim plugin and vscode, but none of them seem to offer autocompletion 21:23

[Coke] vpcc42: No doubt that it's a lot of work to implement.
codesections vpcc42: Yeah, agreed. For whatever it's worth, though, I tend to write Raku without much editor support – I don't really use what's available. Raku code tends to be concise enough that I haven't really felt the need for many IDE tools. 21:37
[Coke] If it's any help, I bought a subscription to Comma as soon as I could, even though I don't get to use Raku very often. Hopefully that helps the community version exist.
