SmokeMachine m: class Bla { method bla("test") {} }; my &bla = Bla.^find_method("bla"); say \("test") ~~ (Signature.new: params => &bla.signature.params.skip) # should this work? 10:39
camelia (signal SEGV)
SmokeMachine m: \() ~~ Signature.new 10:41
camelia (signal SEGV)
lizmat a repeatable SEGV should probably be reported on #moarvm or in the MoarVM repo
SmokeMachine m: say Signature.new
camelia ( --> Mu)
lizmat fwiw, it also segfaults with RakuAST 10:42
SmokeMachine lizmat: thanks. Yes, it does... 10:44

refactus antononcube all he said was to PM him, no other details. the github repo looks like all his recent changes are in the master branch, but I'd hesitate to use it without knowing why he wanted people to talk to him first 18:03

disbot2 <antononcube> Agh, right -- now I recall the DM part ... 18:54
refactus you mentioned you have no way to output 3D plots from raku in a notebook. what does that involve? a raku module that takes some params and a bunch of data and outputs an html page with a webgl canvas and some js for rotating/zooming? 19:17

tbrowder looking for some more design help ref Financeapi.net: it looks like for thr free account, one is limited to 100 queries a day. with some though about how much historical data you need (related to the number of unique security symbols you need, b 20:12
*you can collect a lot in up to as many days as you need. after that, you should be able to keep current daily info with a cron job. 20:15
refactus antononcube I'm going afk for a while but I'll catch up with the scrollback when I get back 20:23
tbrowder i think all that initial data json dump should be put into a relational dbms for practical use...is there a known raku module for doing that? or roll my own? 20:30
the tranfer that is...
lizmat is the fetch of the data once, or do you need to do that every time? 20:32
disbot2 <antononcube> @refactus If any of the JavaScript packages "D3js" or "Google Charts" can produce 3D graphics then Raku can be relatively easily programmed to create 3D graphics. Obviously, that is not the only way to have 3D graphics made. The Raku packages "JavaScripdt::D3" and "JavaScripdt::Google::Charts" do not use canvases and webgl directly (if at all.) 20:33
ab5tract tbrowder: I recommend DB::SQLite
disbot2 <antononcube> @refactus Having 3D graphics would be cool. But if I would work on new Raku graphics features those would be interactive plots of graphics animations. 20:35
tbrowder ah, cro has an Sqlite interface, that may be the ticket... 20:52
20:54 yewscion left
tbrowder lizmat: as far as i have found so far, there is no way to pick a specifiic date in the past, all you can do is pick how long to look back, e.g., 1d, 1wk, 5d 1mo 1y 5y 10y max 20:56
yeah, i think, as ab5tract said, use DB::SQlite to keep the data. the Cro Sqlite use seems a bit different. 21:07
lizmat: i'm not sure i answered you correctly, you only have to fetch data once, if you save it and can use it locally later. 21:16
so i'm going max time in past to fetch data for securities of my interest. then i'll update it as needed. since i'm not playing any market, i only need updates for satisfying the tax man in case we sell something. 21:25

refactus antononcube neither google charts nor D3.js support 3D (which is ironic because D3 is 3D backwards). I'm less interested in 2d than 3d, but I do happen to be currently writing a module for presenting NOAA NWS weather data, which would benefit from good 2d charts. what does "interactive plots of graphics animations" mean, specifically? highlighting and tooltips when you hover over a datapoint? 21:43
tangentially, have you ever considered actually connecting over irc? I hate that I can't see when you're here or not, and that I can't tab-complete your nick :) 21:47
21:48 abraxxa-home left
disbot2 <antononcube> @refactus "Interactive plots" could mean tooltips, but that it is done right now with both packages "JavaScripdt::D3" and "JavaScripdt::Google::Charts". 22:14
<antononcube> I mean interactivity like sliders: generating different, corresponding plot according to the slider move. 22:15
<antononcube> "[...] writing a module for presenting NOAA NWS weather data [...]" -- Is that in Raku? It would be nice to experiment and visualize with it. 22:16
<antononcube> Back to 3D -- I think making a Raku package interfacing to, say, "three.js" should not be that hard. But is that (or other candidate) JavaScript package good for (1) data analysis graphics, and (2) using in notebooks? 22:21
22:23 librasteve left
refactus it is in raku. right now it's just a script I started a few hours ago to pull the data from their API and show it better than their website does. when it's more mature I could maybe abstract it into a module for others to use. long term side goal, thought it'd be cool to have a surface plot of seasonal temps over the years, so you could see the fluctuations over the course of climate change 22:23
and yes 3d would not be that hard, that's why I was asking how much functionality you'd need for it to be useful to you, and what form that would take for it to work in your notebooks 22:24

disbot2 <librasteve> tbrowder: you may also like to take a look at Red … very easy database models 22:26
<antononcube> @refactus To be clear, I am interested in plots like these: visjs.github.io/vis-graph3d/examples/
22:29 librasteve left 22:30 librasteve joined
refactus yeah that's pretty easy. don't even need webgl it that's all you want, could make something like that with SVG and some handwritten perspective projections, sorting back-to-front (painter's algorithm) 22:30
22:31 soverysour left
refactus s/it/if/ 22:31
disbot2 <antononcube> Hmm... there is a host of related functionalities to be implemented. Axes, labels, titles, callouts, legends, scaling, coloring, etc. 22:33
tbrowder librasteve, good idea, it's really come a long way since its inception. 22:35
22:35 librasteve left
refactus antononcube okay, noted, needs features. I'm not trying to convince you it's possible or easy, I was originally asking what kind of output you need it to expose to work in those notebooks of yours 22:40
22:44 apac joined
disbot2 <antononcube> Honestly, notebooks can be ver capricious when rendering JavaScript. That is why I invested a significant amount of time in plotting graphs with SVG. (Via Graphviz.) 22:45
22:47 librasteve joined 22:49 phogg left
refactus is it better if it's svg instead of webgl? 22:56
back when webgl was still experimental I had this idea to write something I was going to call Shadowblade, which projected 3d to 2d and rendered it with SVG or whatever 22:59
but if I understand, what the notebook needs is some sort of HTML output? probably all the things I'm talking about are already written in some JS lib somewhere, that's more of an implementation detail 23:04
if only VRML had caught on :) 23:05
looks like X3Dom is a thing, if you include some JS, but that's still going to be webgl 23:11
