| sjn | is there a way to create character classes based on the content of previous captures in a regex? | 05:15 | |
| e.g. m/( <[abc]> )( <[abc] - [$1]> )/; | 05:18 | ||
| interpolated character class set operations | 05:25 | ||

| [Coke] forgot he wrote github.com/coke/raku-cal to have 'cal' on windows. wow, that is old and needs some updating. | 13:31 | ||
| (needs to switch to app-as-shim-for-lib model and add a META6.json) | |||
| dakkar | uh… I didn't know you could put a pair inside a «» | 13:39 | |

| dakkar | m: say qq:w{:a(1) b}.map: { $^a.WHAT }; | ||
| camelia | ((Str) (Str)) | ||
| dakkar | docs.raku.org/language/quoting doesn't say anything about that… docbug? | ||
| m: say qq:ww{:a(1)}.map: { $^a.WHAT } | 13:45 | ||
| camelia | ((Pair)) | ||
| dakkar | m: say qq:ww{:a(1)} | ||
| camelia | |||
| dakkar | uh… why is it not printed? | 13:46 | |
| m: say qq:ww{:a(1) b} | |||
| camelia | (a => 1 b) | ||
| dakkar | is there a special case for list-contaning-one-pair in `say` or `gist`? | ||
| does it get interpreted as a named argument?? | 13:47 | ||
| (roast does specify that qqww recognises pairs, in `S02-literals/quoting.t`) | 13:49 | ||

| [Coke] | :v is documented as "convert (value) to allomorph if possible" | 14:49 | |

| camelia | (a => 1 ,) | ||
| ugexe | docs.raku.org/syntax/Single%20Argument%20Rule | 14:51 | |
| [Coke] | ordering seems to matter, :v:ww vs. :ww:v | 14:52 | |
| m: say qq:v:ww{:a(1)} | 14:53 | ||
| camelia | (a 1) | ||
| [Coke] | m: say qq:v{:a(1)} | ||
| camelia | :a(1) | ||
| dakkar | ugexe: I'm not sure how single-argument applies without an iterator… | ||
| [Coke]: that last one produces a string, as expected | 14:54 | ||
| [Coke] | for this kind of debugging, 'dd' may be more instructive than say | ||
| dakkar | tried that, didn't help | ||
| ugexe | well that would depend on the signatures of all the functions that end up getting called | ||
| dakkar | ugexe: proto say(|), multi say(\x), multi say(|) | 14:56 | |
| github.com/rakudo/rakudo/blob/mast...#L109-L123 | 14:57 | ||
| ugexe | is say really the only function used? | 14:58 | |
| dakkar | how would I check that? | ||
| ugexe | i.e. Q v etc don't end up calling any functions? | ||
| dakkar | m: my @a=qq:ww:v{:a(1)}; dd @a | 14:59 | |
| camelia | Array @a = [:a(1)] | ||
| dakkar | m: my @a=qq:ww{:a(1)}; dd @a | ||
| camelia | Array @a = [:a(1)] | ||
| dakkar | I *think* that means the difference is in `say`, but I don't know how to check better | ||

| [Coke] | you know say calls '.gist', yes? | 15:01 | |
| dakkar | yes | 15:02 | |
| m: print qq:ww{:a(1)}.gist | |||
| camelia | a => 1 | ||
| dakkar | then again… | ||
| m: print qq:ww:v{:a(1)} | 15:03 | ||
| camelia | a 1 | ||
| dakkar | m: print qq:ww{:a(1)} | ||
| camelia | ( no output ) | ||
| dakkar | *something* is up | ||
| it may well be correct and specced, but I'm not sure where to look | |||
| m: print qq:ww{:a(1)}.gist | |||
| camelia | a => 1 | ||
| dakkar | m: print qq:ww:v{:a(1)}.gist | ||
| camelia | a => 1 | ||
| ugexe | i'm not suggesting its correct or specced, just that it seems like single arg rule might be behind it | 15:04 | |
| dakkar | maybe? why would `:v` (make allomorphs) affect that? | ||
| ugexe | i dunno, presumably :v calls some function to turn a thing into an allomorph? | 15:05 | |
| dakkar | (my starting assumption is "I'm missing something", not "stuff is broken" 😁) | ||
| ugexe: but the weirdness only happens when the result of the quoting is used as arglist for a different call… | 15:06 | ||
| should I open an issue? even if it turn out to be correct behaviour, it may still lead to some doc changes | 15:07 | ||
| m: print (qq:ww:v{:a(1)}) | 15:09 | ||
| camelia | a 1 | ||
| dakkar | m: print (qq:ww{:a(1)}) | ||
| camelia | a 1 | ||
| dakkar | still a single argument, but gets printed | 15:10 | |
| m: print qq:ww{:a(1)} | |||
| camelia | ( no output ) | ||
| dakkar | hmmm | 15:12 | |
| m: sub x(|c) { dd c }; x qq:ww{:a(1)}; x qq:ww:v{:a(1)} | |||

| guifa | (the goal is to try to really go all in on the idea of an in-person conference. I'm really looking forward to it) | 20:10 | |
| drakonis | it'll be quite nice, nonetheless | 20:12 | |
| guifa | I've just got to finish up my talks. I'm a masochist and ended up agreeing to do three of them lol | 20:13 | |
| drakonis | good job! | 20:14 | |
| that said | |||
| coerce protocol talk? | 20:15 | ||
| guifa | for the new COERCE method that vrurg added to core | ||
| drakonis | oh, neat. | ||
| how new is that one? | 20:16 | ||
| guifa | I think it the PR was committed late last year maybe? | ||
| drakonis | oh, neat. | ||
| p6steve | a coerce talk is great - the raku approach to gradual typing and coercion is quite cool... we know it but many don't | 20:18 | |
| drakonis | indeed it is | ||
| p6steve | also nice to hear the subtleties, trade offs and design approach (no pressure) | ||
| drakonis | i got into a perl discussion earlier today and rperl was brought up | 20:19 | |
| it seems like such a weird thing | |||
| coleman | I would be interested in a mailing list for Raku | 20:20 | |
| drakonis | it is very much a half measure towards bringing raku and perl together | ||
| lizmat | rperl? | ||
| drakonis | but it has the ability to output executable binaries | ||
| rperl.org/ | |||
| lizmat | bringing perl and raku together ? | ||
| yeah, I know about rprel | |||
| that page does not mention raku | 20:21 | ||
| drakonis | it was written before the rename | ||
| p6steve | never heard of it - they (rperl.org) do "making perl run faster" -- no mention of raku | ||
| drakonis | back when it was perl 6 | ||
| it is part of a thing called perl11 i guess | |||
| lizmat | yeah, it parses a subset of Perl and generates C++ code | ||
| drakonis | it is more like nqp then | 20:22 | |
| p6steve | no mention of perl6 or raku | ||
| lizmat | perl11 is a pipe dream of the developer of rperl | ||
| drakonis | yes it is | ||
| rperl.org/the_book_of_rperl.html | |||
| it is a strange pipe dream | |||
| p6steve | tobacco? | 20:23 | |
| drakonis | this is not helpful documentation | ||
| no | |||
| hallucinogenic drug fueled trips | |||
| the documentation on cpan is a lot better | |||
| vrurg | rperl is mosly about producing binaries. Not even bytecode, by binaries as such. | ||
| drakonis | i'm interested only in the binaries bit but in raku | 20:24 | |
| which has been stalled for some time | |||
| metacpan.org/release/WBRASWELL/RPe...earning.pm | |||
| vrurg | It makes me feel weird because either it's Perl with all its power; or it's C or Rust for the performance. But castrated Perl?? | ||
| drakonis | that sounds accurate | 20:25 | |
| sienet_ja_LSD[m] | I would use rperl if the documentation was better | ||
| drakonis | metacpan.org/release/WBRASWELL/RPe...b/RPerl.pm | ||
| the documentation is ugly and the cpan docs are serviceable | |||
| it looks a lot like a half-measure since it has a lot of hardcoded stuff that looks like it came from raku | |||
| sienet_ja_LSD[m] | I was supposed to do some OO project with it, but I couln't do it | 20:26 | |
| lizmat | for all practical purposes, rperl appears to be stalled for almost 2 years now? | ||
| drakonis | so it is. | ||
| El_Che | I don't think it went further than esoteric perl being interesting but not used at large | 20:28 | |
| sienet_ja_LSD[m] | maybe I'll try it again if I'll play around with the examples | ||
| drakonis | it is more interesting to use raku anyways | ||
| github.com/wbraswell/rperl/tree/master/docs this has some silly bits | |||
| in special the modes | 20:29 | ||
| rperl.org/the_low_magic_perl_commandments.html this bit in particular though | 20:30 | ||
| it seems to suffer a lot from perl collapsing under the weight of its age | 20:31 | ||
| guifa | the author of that page is … eccentric. | 20:32 | |
| drakonis | i'm... aware... | 20:33 | |
| p6steve | yes, raku is a great lifeboat for perl nuggets - i am really impressed by metacpan.org/pod/FFI::Platypus - and trying to rekindle in Dan::Polars | ||
| El_Che | trying to get C performance in a safe language is kind of the Holy Grail :) | 20:34 | |
| p6steve | err - no its Rust | ||
| El_Che | nah | ||
| drakonis | i wonder why rperl has a operator for crypt lol | ||
| p6steve | not fast? not safe? | ||
| El_Che | it came and it did not take over the world, and not for lack of attention | ||
| drakonis | rust has been eating up some marketshare | 20:35 | |
| it takes time to displace the existing options | |||
| El_Che | slowly | ||
| p6steve | yeah - I've spent weeks knee deep in rust and it's hard | ||
| drakonis | since you can't replace C or C++ with it overnight | ||
| then there are spaces that it needs a lot of investment to break into | |||
| El_Che | p6steve: I like the simplicity of Go | 20:36 | |
| drakonis | like the data science space | ||
| El_Che | p6steve: so did most devops people so it took that space where it was not intended to | ||
| p6steve | you cant replace [Perl|Python|Ruby|PHP] (with raku) overnight either | ||
| guifa | As with all things, there are trade offs | ||
| drakonis | indeed not. | ||
| El_Che | it's a different comparison | 20:37 | |
| drakonis | you can however write something useful that will slowly eat up the marketshare at the edges | ||
| wrt replacing the common scripting languages | |||
| El_Che | there is stuff where perl and co still beat raku | ||
| drakonis | except usability and long term flexibility | ||
|
20:37
moon-child left
|
|||
| El_Che | there are advantages, but people care about different things | 20:38 | |
| ans like p6steve implied, there is inertia | |||
| drakonis | and inertia is truly a powerful thing | 20:39 | |
| p6steve | El_Che: then try Occam! | 20:40 | |
| El_Che | 's razor | ||
| :) | 20:41 | ||
| when and if I had the time I would like to pick up some rust | |||
| drakonis | occam, eh? | ||
| p6steve | El_Che: can always work on Dan::Polars ... | ||
| El_Che | having a look | 20:42 | |
| p6steve | sadly a bit early | ||
| El_Che | p6steve: you're into data science :) | ||
| p6steve | learning as I go | 20:43 | |
| yes occam: if it can fail, it will fail | |||
| El_Che | the rust integration looks more promising to me than inlining python | 20:44 | |
| python (and perl and ruby) are terrible to deploy | |||
| (that's why go took devops from python) | |||
| so maintaining several stacks of languages is not something I would like to do | |||
| but on the other hand, I don't see people porting Panda :) | 20:45 | ||
| p6steve | we need Python for some level of feature completeness, interop for newcomers/compatibity and workflows to eg plotting | ||
| BUT rust/pandas/arrow2 is a good match for raku (fast, lazy, better API) | |||
| rust is nice to deploy as a lib | 20:46 | ||
| just a pig to code | 20:47 | ||
| El_Che | so nativecall is lipstick :) | 20:48 | |
| p6steve | the notion with Pandas is just EVAL anything that looks like df.pl.XXX() ... so just have to maintain as a proxy | ||
| well Polars Python binding uses maturin - we have nativecall :: rust FFI and nothing in between | 20:51 | ||
| no - raku is the lipstick! | 20:52 | ||
| drakonis | lipstick on a pig, eyyyy | 20:56 | |

| El_Che: and you can add rust to your CV | 21:00 | ||
| drakonis | how long until rakuast is merged into the main branch? | 21:02 | |
| also, how long until the opposite happens? | |||
| El_Che | p6steve: I am not in that field | ||
