Xanozoid can Raku be ran client-side in a website? 02:08
Xliff Actually, it can with rakudo-js
Xanozoid is that the official name for it? or is that a supported target via Rakudo? I can't really seem to find much on the web about that 02:09
Thanks Xliff

chloekek I recall somebody was interested in packaging Rakudo and Raku packages for Nix, but I don’t recall their name. 15:04
Thing is, for doing that I was working on this index of packages called CRAI and I’m not sure if I want to continue running it. 15:06
Right now it is not all that useful; it indexes all archives from CPAN and p6c every hour and displays metadata about them on a website. This includes the URL and the hash, which are very useful for package managers. 15:07
Considering I’m not using Raku all that much I’d like to not run that server anymore as I currently pay for hosting it every month and I don’t think anyone is using it, but the software may still have potential. 15:08
regreg chloekek, how much does it costs to run the server? and what about time sunk? 15:09
chloekek Oh lol it’s only 6 EUR apparently. 15:10
rba chloekek: what is this used for exactly?
regreg i could pay for it if it has any use for the community but i don't know how to manage it 15:11
chloekek rba: There are currently two places where you can find Raku library archives: CPAN and the ecosystem repository. CPAN provides an easy way to download specific versions (archives) of libraries, but the ecosystem does not as it just points to Git repositories’ master branch.
rba If there is common community usage, I might take it over under the umbrella of raku infra.
regreg but it will have to wait until i receive next disability payment (which will about around 12 march)
chloekek rba: So I wrote a cronjob that periodically downloads all those libraries though stable tarball URLs, and computes their hashes. This information could be useful if exposed in a machine readable format, but I don’t really have the time to work on that. 15:12
It generates a SQLite database that has a table in it with (tarball URL, tarball hash, META6 extract)
rba Does it overlap with modules.raku.org or zef?
chloekek modules.raku.org only seems to index latest version of each library, and does not provide hashes. 15:13
Without hashes, you don’t really know what you are downloading.
The problem is really with ecosystem repository, it just points to Git repositories, but those don’t tell you how to get a specific version of each library.
rba Got it. I will take over hosting. Who is taking over the development?
chloekek Say you want Foo::Bar v1.0. You would need to clone its git repository and search the git commits for the one that bumps the version to v1.0 in META6.json, except for the rare case of libraries using Git tags. 15:14
And even then, the author could release v1.0, then update the repository to include malicious code, and change the tag to refer to the new commit, and people would suddenly be deploying that. 15:15
rba May we look into details later today. 20:00 CET or later, or this sunday? 15:17
chloekek Sure.
May open an issue on problem-solving about archiving and version discovery. 15:18
jmerelo: was also interested in this.
tellable6 chloekek, I'll pass your message to jmerelo
chloekek Here’s an example of what it indexes: crai.foldr.nl/archive?url=https://...e8c.tar.gz 15:21
rba Chloekek: problem-solving makes sense.
15:21 Altai-man_ joined 15:22 _jrjsmrtn left
chloekek I suppose integrating the cronjob into modules.raku.org would make sense, but we’ll discuss this on/after the problem-solving issue. :) 15:24

san_goku_ssj_10 rypervenche thanks. It's impossible to change the value of the variable inside the routine ? 23:48

san_goku_ssj_10 I have try it 23:50
but I have this error message
Parameter '$message' expected a writable container, but got Str value in sub message at main.pl line 3 in block <unit> at main.pl line 10
rypervenche Ah yes, I'm wrong there. 23:51
Try "is copy" instead. 23:52
That works.
