SmokeMachine Is there already a link for the Raku conference? 11:04
tbrowder g'day. visiting IO::Path again, it seems unfinished that IO::Path.parent has no terminator. that is to say that, for a real file $f with no more than 10 parents will give the same result with $f.IO.parent(100). 11:07
lizmat m: dd "/".IO.parent # hmmm.... 11:08
camelia IO::Path.new("/", :SPEC(IO::Spec::Unix), :CWD("/home/camelia"))
lizmat tbrowder: so you'd argue that should probably create a Failure ? 11:09
tbrowder or do something. i would like to see something like this to return the "top" parent IO::Path.parent(*) 11:11
and make IO::Path.parents return a number 11:12
of parents
Voldenet I agree with the .IO.parent point
giving "/" to a script is an edge case otherwise
tbrowder exactly 11:13
right now i have to test for "/" at every step
Voldenet right now my scripts don't even support that properly, because I know to not run them in root 11:14
which isn't exactly elegant convention
tbrowder anyhow, i know lizmat, coke, and vrurg can come up with an elegant solution 11:15
what time is raku conf kickoff? 11:17

camelia Impossible coercion from 'Int' into 'Assignable[Int]': method COERCE returned an instance of Int+{Assignable[T]}

lizmat tbrowder: the problem with IO::Path.top is that on Windows, there is not a single top 12:15
C:\ and D:\ would both be top, no ?
I'd rather see a method "is-top" on an IO::Path that would return a Bool indicating there's no more parents 12:16
Nemokosch +1 for a link for the conference... 12:24
Voldenet I'm not sure if uniform path handling is going to ever work well on windows 12:25
for example `raku -e $*CWD.IO.dir.say` on windows can fail easily
tbrowder lizmat: that would work for me 12:26
12:27 deoac joined
Voldenet which happens when $*CWD is unc path 12:27
on win2003 \\?… is correct unc path, on vista+ it isn't
tbrowder well Windows people should pick a better OS! ;-D 12:28
Voldenet I wish windows was more unix like, eh
tbrowder you bet! 12:29
lizmat: how about the IO::Path.parents method retuning number of parents (counting is-top)? 12:31
Voldenet imo msys2 does the right thing: /c/whatever becomes `c:\whatever` and `//whatever/test` becomes `\\whatever\test` 12:33
lizmat so that $io.parents.tail would give yu top ?
Voldenet imo .parents.tail should return '/' on unix and 'drive:' or '\\servername' 12:45
lizmat not drive:\ ? 12:46
I thought drive: implied current directory on that drive Voldenet ? 12:47
Voldenet you can do `dir c:`
it's somehow weirder for UNC paths 12:49
because in most tools \\servername is not a proper root
you can't `ls \\server`, `ls \\server\path` is valid 12:50
tbrowder if we’re looking at a parent dir, what about getting children? (without File::Find)?
Voldenet .dir(:recursive)? 12:52
tbrowder sorry just first generation :~) 12:53
Voldenet continuing the above, on msys2 bash I can just `ls //server`, which is totally weird, but consistent 12:54
tbrowder or specify depth of search
file child vs dir child 12:55
Voldenet (in powershell you need `net view \\server` which is a few more layers of weird)
tbrowder hm, looking like good parts of File::Find! 12:56
one of my fav modules 12:59
Voldenet I've thought about it and drive:\ is more sane 13:12
13:27 evalable6 left, linkable6 left 13:28 linkable6 joined 13:29 evalable6 joined
Voldenet either way, probably more difficult issue is properly handling unc paths, because there's no good default on whether "\\whatever\" should be included as top parent or not 13:30

[Coke] "on vista+ it isn't" - do we need to be supporting vista with even code examples at this point? 14:33
Voldenet I'm not sure what is supported when you run raku in compatibility mode on windows, but probably not 14:38
(vista+ is the current state though)
(win2003 is still in use, but unsupported) 14:39
[Coke] sorry, how to run raku in compatibility mode? 14:43
I am just... running it.
ah. You can manually choose to run something in compatibility mode - but why would you do that? 14:44
Nemokosch it only goes to Vista anyway
[Coke] That sounds like a DIHWIDT.
Nemokosch on Windows 10
Voldenet either way, I have not seen \\?-style paths in a while 14:48
[Coke] +1 14:52
(Something that could be part of the documentation, supported versions of windows when looking at OS-specific methods) 14:53

[Coke] Can we get a ticket on the backlog to stop installing "perl6" executables? 14:54
... dammit. :)
Voldenet I've checked and .net doesn't support that 14:55
lizmat The 2nd Raku Conference has started! conf.raku.org 15:02
Voldenet til perl6 is not a symlink to raku 15:04

ugexe \\? style paths are used internally at the libuv level 15:34
which allows long paths to be used 15:35
also libuv only supports >= windows 8 15:45

ingy microsoft.github.io/language-serve...ification/ lists `perl6` 17:26
someone should PR that
lizmat where would that need to be PRed ? 17:27
ingy My guess would be add `language-server-protocol/specifications` to github.com :) 17:28
bad guess :) 17:29
lizmat thanks 17:30
ingy domains like lizmat.github.io/foo are gh-pages web pages for lizmat/foo repo (as I'm sure you figured out) 17:33
lizmat if you set that up, right ?
ingy yep

lizmat: fyi using your own domain name there is easy peasy if you want. I use gh-pages for almost all my sites. 23:04
lizmat ingy: will look at that tomorrow... first some shuteye& and thanks again for the nudge
ingy sure, but it wasn't even a nudge. :) 23:05
