lizmat: making great progress on hugely improving CSV-Autoclass 'cause i'm using it installed locally for another project. no promises, but i may be able to push out another advent article later. 00:34

melezhik how can I iterate though all symbols provide by module export (exported functions) when requiring  module (not loading it) ? 09:11
docs.raku.org/language/modules#require example only shows how to reference to a specific symbol (function name), but I would like to iterate through all of them 09:12
looks like this - 'require Foo;  say Foo::.keys' 09:20

clarkema1 I decided to have a play around with testing Readline on openbsd, just for fun. On a fresh installation of 7.4, I had to patch zef's tar detection routine to get it to work, but am now encoutering the following: gist.github.com/clarkema/ec15c0fbc...6ab47d3b7a 23:07
I'm at a bit of a loss as to why it would be failing to recognise, or (alternatively) incorrectly creating the 'dist' directory just on openbsd
I've tried getting it to use gnu tar for the extraction just in case that was making a difference, but that doesn't seem to have helped -- any ideas welcome! 23:08
23:13 sena_kun left, sena_kun joined 23:14 sena_kun left 23:16 antim0d3s joined 23:17 sdfgsdfg left
clarkema1 ah, never mind -- it _is_ a gnu vs bsd tar issue. I'll keep digging 23:20
23:27 jpn joined
ugexe what did you need to update re tar detection? 23:32
23:32 jpn left
clarkema1 ugexe: I'll do a PR once I've run down the second issue, but in short github.com/ugexe/zef/blob/main/lib...akumod#L93 23:34
just running bare 'tar' on openbsd doesn't output any of the magic words
obsd-test$ tar
tar: Failed open to read on /dev/rst0: Permission denied
So I changed to BEGIN my @needles = <archive file specify /dev/rst0:>; 23:35
ugexe I dont remember how I came up with that detection on openbsd 🤔
clarkema1 Tested on 7.4, and I've checked the bare tar output on an old 6.8 machine and it's the same 23:36
bare tar on FreeBSD gives this: `tar: Must specify one of -c, -r, -t, -u, -x`, so maybe it used to look similar on openbsd, but if so it was at least prior to 6.8 23:38
ugexe i probably just asked chatgpt to pretend to be an openbsd command prompt or something
clarkema1 lol
ugexe i guess there is no way to get a more... complete?... help output? 23:40
clarkema1 it doesn't appear so, other than by making it barf to generate a usage message 23:41
gist.github.com/clarkema/7ead2ff13...8388432466 23:42
of course, an openbsd installation that doesn't have /bin/tar is pretty damn broken, so its presence could be assumed
The second issue is a missing 'z' flag further down the file, which gnu tar is cool with but not bsd tar 23:47
just testing now
ugexe i'm not sure it is bsdtar, because macos and windows both come with bsdtar and work 23:49
clarkema1 ah, well maybe it's just openbsd /bin/tar being special then. I have no idea when they all forked off each other
how do you feel about the detection change, before I do a PR? Would you prefer some other test? 23:52
ugexe I'm fine with making the detection work, i'm just not sure the best way to do it. Adding a check for `/dev/rst0:` probably doesn't work if /dev/rst0 actually exists. adding a random flag can potentially break in a future version of tar. Ideally there would be some parameter/flags that could be used to get either a 0 exit code or deterministic output. I'd accept a PR regardless as long as some 23:55
consideration is given to those concerns before submitting though
clarkema1 Fair point. Sadly I don'th have a tape drive lying around 23:56
One option could be to ship the world's smallest tar file and try to extract it 23:57
ugexe ah, is /dev/rst0 always gonna be a tape drive?
clarkema1 yeah
ugexe ah, then maybe it is fair to check for that then. if someone has a tape drive i suppose they can file a bug report and then we'll figure out a better option
clarkema1 tar -cf - exits silently and succesfully 23:59
