moritz depends on what you need to do with it 06:48
maybe the simplest is to simply add it to all candidates
if it's just one central action, it may be possible to do it in a proto, but I have no idea if that interferes with the introspection into the multi signatures 06:49

elcaro Altreus: Seems like a perfect fit for a Proxy 11:13
see my accepted answer to a similar question here: stackoverflow.com/questions/552507...c-in-perl6 11:14
in fact you could make a generalized `valid` sub that acceps a validator function, and returns a Proxy that validates against that fuction in the STORE method or throws/dies 11:15
moritz are you trying to reinvent subset types? 11:16
m: subset SmallerTen of Int where * < 10; my SmallerTen $x = 5; $x = 20; 11:17

Demos[m] lizmat: ah that triggers a rakudo bug in my copy of rakudo
(the latest rakudo star)
lizmat yeah, parameterization of QuantHashes is relatively recent
Demos[m] what does dd do? 11:26
moritz m: my Int $x = 42; dd $x
camelia Int $x = 42
Demos[m] oh, found it
elcaro moritz: yeah, good point... Proxy's are mainly useful when you want to attach additional logic around STORE or FETCH
lizmat basically: note @args>>.raku
moritz Demos[m]: it prints out stuff for debugging
Demos[m] but can I use it to format my hard disk? 11:29
El_Che sure, surround it with shell() :) 11:33
moritz with enough creativity, everything is possible

El_Che lizmat: the day apple made the awfull itunes optional in windows for using its devices, the macos users were doomed :) 12:21
lizmat possibly, otoh it would appear to me that JITting should be either a simpler task on ARM equipment, or less needed ? 12:22
El_Che feasability: it's a more easier arch, but I have no idea honestly. Less needed, I wouldn't think so. The mac laptos will be underpowered. 12:23
my mac airs with macos feels a lot slower than the 4y older i7 laptop with ubuntu 12:24
12:27 rindolf joined 12:28 titsuki joined
lizmat well, they do seem to target the cheaper models (aka underpowered) models first 12:31
12:40 p6steve joined, Doc_Holliwood left
El_Che Thing is, I think, that those are the models people buy if they mac is not provided by $work 12:40
lizmat well, as jnthn pointed out, the only thing you won't get is JIT, it would still have spesh and inlining 12:41
El_Che I run Linux at work, but if I wasn't allowed I would moved to mac before using win 10. But even then I wouldn't really ask for a 2500€ laptop at work :)
now I ask for many somwhat cheaper :) 12:42
so I can run all os'es :)
although Dell Latitutes are in way cheap nor low range :) 12:43

Altreus I have previously made the decision to use a mac instead of a windows 10 machine 13:23
I do not regret it
nor do I now have a mac or any desire to own one :P
(I have also previously installed debian on a mac, back when they used the powerbook architecture) 13:24
raschipi People, please stop, I'm already sweating just thinking about these things. 😅 13:29
jnthn If Apple keep up making it such a nuisance to ship software to run on Mac, I wonder how many projects will just think, screw it.
raschipi Microsoft wants the same, and is already taking steps to make it so. 13:32
Windows 10 S, used on the Surface, is already this way. 13:33

AlexDaniel we need JIT on ARM anyway 14:05
for all SBCs out there
hm that probably means both 64-bit and 32-bit… 14:08
jdv79 need is a strong word 14:10
14:10 chloekek left
AlexDaniel “we” is also a strong word 14:10
*I* need JIT on ARM, please :)
jdv79 diverting resources just for jit on arm - idk - if i had to pick between that and almost anything else 14:11
jnthn Probably fully switching over to the expression JIT is a pre-req for sensibly doing ARM JIT 14:12

lizmat I sorta expected all of those to give NaN 14:30
or a Failure
now for something completely different: Pictures! twitter.com/liztormato/status/1253...4237483016
AlexDaniel lizmat: omg! Amazing! 14:31
so many camelias ♥
jnthn lizmat: Failure maybe, but cmp is spec'd to return Order, and I don't think Order or Num is much good; Order with the usual Failure sneaking through rule could work I guess 14:32

raschipi lizmat: Could you ask Wendy for a more explicit license because sometimes it's a requirement. 14:41
Oh, now I found it. 14:42
I think the NonCommercial limitation is a problem, though. Can't be used by anyone actually involved in Raku or any of it's websites, since all of them are commercial. 14:44
Unless that's what is intended the intention. 14:45
Anyone that wrote a book about Raku also can't use it. 14:46

Demos[m] raku's MAIN multi sub is real neat 15:26
raschipi What I think is even neater is that the whole language was shaped to make MAIN fit very well. Very well designed, the features aren't just bolted on. 15:45
15:45 p6steve joined, stoned75 joined 15:49 k-man__ joined 15:51 k-man_ left 16:04 ensamvarg2 left, ensamvarg_g6 joined
Demos[m] I consider bolted on features a feature of perl (and raku) 16:11
I love the live and let live attitude perl has
(and raku)
Real question though: Is there a way to instruct rakudo's build system to link additional static libraries? 16:12
Kaeipi i haven't really seen HyperWhatever get much love 16:14
m: say (1...10).map(*+1)
camelia (2 3 4 5 6 7 8 9 10 11)
Kaeipi m: say (1...10).&(**+1)
camelia (2 3 4 5 6 7 8 9 10 11)
Kaeipi useful for one-liners ig
didn't mean to interrupt tho, didn't see i was scrolled up when i sent the first message 16:17
Demos[m] also: is there a way to add a trait for every sub in a block 16:26
I wanna add "is native('...') is export without having to write it every time
jnthn Demos[m]: No, there's no way to factor that out, though it's typical to have a `constant` for the native library name so that isn't repeated. 16:29
moritz this would be a good use case for macros (but probably not in the first macro iteration)
Demos[m] I mean I should be able to define a sub that just creates the native sub and adds it to the module via the MOP right? 16:31
or a YOLO slang :D
oh also, on the native call front: is there a way to override the library name?
jnthn The MOP is about OO stuff. You could define your own trait_mod that applies the two, however. 16:32
Demos[m] I want to be able to distribute my application as a single executable, that incluedes the interpreter, static linked to the libs I need, and my files
jnthn And that will mean there's only one thing to repeat
Demos[m] mmm that could be good
Well you can muck around with ModuleHOW no? 16:33
jnthn I don't see how it'd help you really; subs are lexical
So there's not a way to reach them via ModuleHOW 16:34
The language generally has a quite strict early-bound (lexical) vs late-bound (objects) split.
16:37 dakkar left
Demos[m] so I guess my own trait, or a YOLO slang 16:41
moritz well, you could always have a list of subs 16:43
apply-traits( sub a(...) { }, sub b(...) { }); 16:44
that way apply-traits gets a list of subs as arguments
and can go wild :D
jnthn Not really because traits should be applied at BEGIN time 16:46
I guess you can try sticking a BEGIN before calling apply-traits

HTH
logs: repo.westus.cloudapp.azure.com/raku...662128.txt
repo.westus.cloudapp.azure.com/raku...661668.txt
weird enough, but now details are seen on logs 17:24
verbose mode is not enabled in rakudist, but it's rare when it is really needed 17:25
vrurg melezhik: and this is actually when verbose is needed the most, I guess. :)
melezhik yeah, but in 99% default `zef install` produces enough information ... 17:26
I can tweak rakudist harness though and rerun test
5 minutes
have launched new build with verbose mode enabled, so let's see :-) 17:27
repo.westus.cloudapp.azure.com/raku...662831.txt 17:28
vrurg Aha, thanks! Meanwhile, Linux Mint – installed with no problem.
Demos[m] Can I make new allomorphs? 17:30
vrurg Demos[m]: p 17:31
Sorry, wrong window. :)
Demos[m] ummm
were you addressing me in another window? 17:32
vrurg Demos[m]: it's autocompletion.
But, anyway: look for but
Another way is to have a class coercing the way you need it. 17:33

sena_kun El_Che, no? 17:42
El_Che no
I misread
it's 2019.03 changelog
sena_kun El_Che, 2020.03 starts with "Add a Raku REPL with multiline commands, history, auto-completion of symbols, and the usual range of annotations and intentions". ;)
El_Che not 2020.03
17:42 p6steve left
El_Che so the changelog is not for 2020.01.0 17:42
still mismatch, but not the one I wrongly saw 17:43
sena_kun El_Che, no, it is correct.
El_Che ah ok
sorry for the noise then
sena_kun El_Che, it says "migrated to 2019.03", but this is because we indeed migrated (well, for community folks) in 2020.01. 17:44
El_Che yeah, I get that now
melezhik so vrurg: it's test failure - repo.westus.cloudapp.azure.com/raku...662831.txt 17:45

vrurg melezhik: I can't test on docker, it doesn't support macos. Otherwise the log is still pretty much useless. The failed test is a subtest which is in turn a bunch of subtests too. :( 17:48
melezhik yeah. i can't help more, it run in verbose mode. other than run stuff from docker manually ... 17:49
I can't test on docker, it doesn't support macos"
this is why rakudist exists
17:51 aborazmeh joined, aborazmeh left, aborazmeh joined, andrzejku joined
vrurg melezhik: I think there is an env var which causes zef/prove to output all test messages 17:53

zef --debug ? 18:02

melezhik but I doubt it will give us more info 18:02

i was thinking of using grammars as a quick way to implement a VM 18:44
and i guess turning the sequence of operations into a string works, except for cases where an operation also changes the sequence itself 18:45
but i guess grammars might not be the right tool for that 18:46
guifa2 x[LGWs4x4i]uG2N0: basically. For old-school regex (like, in 8-bit encoding era) there wouldn't be muchof a question because there wasn't much of a distinction between a string and a blob, they were both totally arbitrary pieces of data taken in 8bit chunks 18:47
Most (all?) regex engines these days are focused on string processing, and strings today are ...more complicated today :-) 18:49

jdv79 is there a fast yaml module? 20:15
i have a feeling YAMLish is slowing my stuff down 20:16
20:16 girafe left
MasterDuke have you profiled (i love that rakudo comes with one built-in)? 20:16
jdv79 uh, i haven't been able to get a browser to load a real profile in a long time 20:18
i just added something with YAMLish and now its dog slow - gotta check though
20:18 rindolf left
MasterDuke timotimo's moarperf handles large profiles (you have to generate sql profiles though) 20:20
jdv79 oh nice. i pulled a large chunk of code into the "script" as well - that's it 20:21
compilation speed
nevermind then
20:21 girafe joined
jdv79 i tried a few times to do the more complicated profiling stuff but could never get it to work 20:22
be neat if it was like Devel::NYTProf - that profiler is amazing
MasterDuke it currently has a problem with the
index page redirect. you may have to manually to go localhost:20000/#/prof/home/ 20:23
20:23 stoned75 left
jdv79 iirc they wrote the profiler and then stopped using perl, in part cause it was slow. 20:24
jnthn jdv79: I replaced YAMLish with YAML::Parser::LibYAML in one codebase doing a load of YAML and got a significant speedup
SmokeMachine I was thinking… is there a way of creating custom types that work like Junctions? I mean: not child of Any and if passed to a function expecting that type would just run the function as usual and if it expect Any it would behave differently (eg: run multiple times (or no time at all) on parallel as Junctions do).
jnthn It does have a native dependency, however.
MasterDuke jdv79: huh, didn't know that history
jdv79 ah, i'll try that 20:25
raschipi SmokeMachine: That's what we want macros for.
jdv79 if it runs anywhere it'll be in a docker thing so no issue with a native dep
SmokeMachine raschipi: by macro you mean the function would be a macro or the RakuAST would give us power to change it behaviour? 20:27
raschipi Well, a function isn't a macro and RakuAST isn't macros either, so I'1m a little confused about what you mean... 20:29
SmokeMachine I was wandering about having a Junction like Maybe type, for example, and if you do `any-function($my-maybe)` and it’s Nothing, than it would not run the `any-function` and would return Nothing again... 20:30
raschipi: I meant how would you implement that with macros? 20:31
raschipi Well, have the macro expand to code that checks the type and do different things depending on it. 20:37
20:38 molaf joined
SmokeMachine raschipi: so I’d have to implement the “function” as the macro… and I was thinking as a general thing to use on any function/method... 20:39
