Xliff How long does it take to Lock.protect? I am trying to have events write to the screen every 0.05 seconds. I will need to Lock.protect the screen while each element draws. Given that this is a TUI, I shouldn't have much trouble doing this with Raku, should I? 00:14

Voldenet Xliff: last time I've check lock.protect took around 3us, so you can have 1000 components just fine - it depends if you are going to render scrollable lists with N items in TUI 08:37
tellable6 Voldenet, I'll pass your message to Xliff

melezhik o/ 08:54
what RakuAST is going to change for "mere mortals"? My lasting expectation from Rakudo is performance , will it decrease rakudo programm start up time? 08:56
lizmat no: RakuAST only lives at compilation, and most likely when you start your rakudo program, it already has been compiled 09:02
and the bytecode (at least initially) will be the same as with the legacy grammar, or even less optimized (again, initially) 09:03
melezhik i mean when I say descrease start time, time required to program to start when compiled data already in place is still wanting, at least for _my_ case ( Sparrow launches a lot of Raku proccesses and this is by design ) 09:05
just in general I wish rakudo will take less time to start a program 09:06
and hoped that RakuASK could do something about it, and now I see it is not, byt thanks for clarification anyways 09:07
Raku proccesses -> Rakudo proccesses ( when a whole new programm gets run as a separate proccess ) 09:08
Voldenet for that use case, I bet it'd be nice at some point to be able to reuse the compiler without reloading everything 09:11
melezhik yeah, unfortunatelly or likely sparrow designs relies on separate procceess which makes some things very easy, and other things very hard 09:23
Voldenet Have you checked whether checkpointing (criu?) would help?
melezhik what's that? 09:24
Voldenet the technique that lets you save running process into binary 09:25
I don't know whether startup time is slow enough that this would help though 09:26
09:26 yewscion_ joined
Voldenet and it would definitely complicate loading actual code 09:27

melezhik yeah 09:56

wayland76 .tell melezhik Regarding AST, while there's no optimisation improvements yet, it should give the opportunity for better optimisation in some cases. In dev.to/fco/the-future-of-red-orm-for-raku-44gf skim down to the section called "The promise of RakuAST". Short version: We might be able to compile some blocks to SQL and run them on the database server. 11:11
tellable6 wayland76, I'll pass your message to melezhik
wayland76 Btw, the first hit for "red ORM ast" is still a Wikipedia page about a Viking story from the 10th century :) 11:12
No, my bad, a novel (1940s) set in the 10th century. 11:13
SmokeMachine usercontent.irccloud-cdn.com/file/.../image.png 11:14
stanrifkin Terminal::LineEditor does not support CTRL-L for clearing the screen, right?
wayland76 www.google.com/search?client=firef...ed+orm+ast
SmokeMachine yes... on google I got that... but my default id ddg... :) 11:15
wayland76 stanrifkin: According to raku.land/zef:japhb/Terminal::LineEditor it does "refresh-all", whatever that is. 11:16
SmokeMachine: Nice! I tried it a few years back, but didn't quite manage to tear myself away from Google yet.
SmokeMachine wayland76: thanks for talking about that post... maybe that will help to change the first occurrence on google...
wayland76 haha, no worries :) . 11:17
Hmm. For just "Red Orm", it's not even in the top 10 on Google. That's more important to change. 11:18
Also, I'll probably at some point want to discuss whether there are any useful points of collaboration between Red ORM and the Table-Oriented Programming stuff. 11:19
But I want to finish more Table-Oriented Programming stuff before we get into that very far. 11:20
SmokeMachine wayland76: please, let me know when you want to discuss that (or any other thing...) 11:21
wayland76 One big difference though -- I want Table-Oriented Programming to support not just SQL, but also spreadsheets, and in-memory tables. And CSV files.
I've currently got some basic TOP stuff going (I can make tables in either memory or Postgres with pretty much the same code, and can eg. read in a Linux command output as a table, and spit it out as a CLI table, or a CSV), but I'm currently working on the TOP operators (so that we can do a join between a CSV file and a Postgres table) 11:23
Once the operators are done, there will be a few bits and pieces (ie. groups of columns), and then I'm going to call it MVP and put it on the back burner so I can do Tree-Oriented Programming (think being able to use XPath/XSLT operations in Raku code). 11:24
(Just trying to give some idea of a timeline) 11:25
I'll probably talk to you once I have MVP and before I put it on the back burner.

melezhik SmokeMachine: it could be that search engine uses your browser search history via cookie and shows you results wrt previous search 13:22
tellable6 hey melezhik, you have a message: gist.github.com/6f0beb43a2b5cc2bfb...fe874b91f9
melezhik wayland76: thanks
wayland76: viking - not bad assosiation for Red BTW )) 13:23
SmokeMachine: in other words you may try to repeat the search from browser anonimous mode, my assumption might be incorrect though, just guessing ) 13:25
SmokeMachine wayland76: I had a project to create a role called Reddish that one would implement a few methods and it would give Red interface to anything... I never had time for that...
melezhik: I'm not really sure how it works on ddg... 13:30

librasteve The narrative is set in the late 10th century and follows the adventures of the Viking Röde Orm - called "Red" for his hair and his temper, a native of Scania. lol 17:00

timo Voldenet: would you like to investigate criu for faster rakudo startups? 18:27
i'm also interested in seeing that 18:29
antononcube There is a graphs (hamiltonian paths) question in Mathematica.StackExchange that can be answered with Raku implementations in "Graph". I think it is fine to file separate Raku-centric StackOverflow question, right? 18:32

test-docker-image.yml: Test Docker images also for all version bumbs

Let's do a Docker image build also on every new Rakudo-Star version, not only on `Dockerfile` changes.
Should hopefully discover issues BEFORE we even get into issues with the `official Docker image build`, see also
