raydiak I just tried and encountered the same problem. It worked after a `sudo ln -s /usr/lib/perl5/5.34/core_perl/CORE/libperl.so /usr/lib/`. perhaps there is a way to specify an additional path to check for native libs? 00:27
moon-child one way is LD_LIBRARY_PATH, but... 00:29
raydiak could that be an indication that I need to do something special with ldconfig or fiddle with ld.so.conf or whatever? should there already be a symlink to libperl in a standard location? do I have to remember to fuss with this every time my distro updates perl? 00:33

moon-child more likely is that libperl.so is hiding away because it doesn't want to be linked against 02:02

elcaro I think there's a bug with ~& (yes, yes... stringy bitwise-AND... very popular operator!) 04:18
doc says: Coerces each argument to a non-variable-encoding string buffer type (e.g. buf8, buf16, buf32) and then performs a numeric bitwise AND on corresponding integers of the two buffers, padding the shorter buffer with zeroes.
but it doesn't look like any padding is occuring
m: say 'foo' ~& 'bar'; say 'foo' ~& 'barssssss'
camelia bab
bab
elcaro I'm guessing should look like this... 04:19
m: say Blob.new(|(0 xx 5), |('foo'.encode) Z+& ('barssssss'.encode)).decode
camelia ␀␀␀␀␀bcc
elcaro or... something
Raku just punts directly to nqp::bitand_s 04:20
so my question is... should the paddding be happening in rakudo or in nqp?
nqp tests for bitand_s only tests for equal length strings
m: say Blob.new(|(0 xx 6), |('foo'.encode) Z+& ('barssssss'.encode)).decode # I missed a zero before 04:22
camelia ␀␀␀␀␀␀bcc
elcaro and maybe "padding" means after... and maybe that depends on Endianess of the system... I dunno 04:23
moon-child elcaro: honestly that looks like a doc bug to me 04:27
padding with ones feels more correct, as they're the identity element for and
I'm guessing that string was pasted from the doc for or, which does use 0
ah...hmmm 04:28
roast has a test: "aaaaa".encode ~& "aa".encode eqv "aa\0\0\0".encode 04:29
m: say "aaaaa".encode ~& "aa".encode
camelia utf8:0x<61 61 00 00 00>
moon-child m: say "aaaaa" ~& "aa"
camelia aa
moon-child m: say ("aaaaa".encode ~& "aa".encode).decode
camelia aa␀␀␀
aa␀␀␀ 04:30
04:31 sono joined
elcaro moon-child: changing the docs is _easier_... but the bitwise AND should pad the shorter buffer. it's more useful that way 04:31
i will raise an issue anyways
moon-child r: say "aaaaa" ~& "aa" 04:33

raydiak .tell lucs apparently zef is not the best way to get it running (though you can make it work with the symlink workaround I mentioned earlier). I just tested building with the instructions at github.com/niner/Inline-Perl5#building and that worked flawlessly without workarounds 08:41

too much debris in the river, whole trees and other big things 10:47

tellable6 hey lucs, you have a message: gist.github.com/950200490e208b85e2...62e7af768e
lucs raydiak: Soryy, I'd missed your comment about linking to the lib. Also, I'll go read the build instructions on the github page. Thanks! 13:29
Hmm... So, wondering how/if Inline::Perl5 handles possible multiple Perl installations (from perlbrew for example). 13:52
Altreus TIAS? 13:54
:) 13:55
I'm interested too, but only because you brought it up
lucs I TIAFailed :) 13:57
moritz lucs: I would expect that Inline::Perl5 uses the Perl 5 that was active when it was compiled 14:01
lucs moritz: I got this error when I tried that with a perlbrewed 5.34.0 (with the -Duseshrplib option, yes): gist.github.com/lucs/9fdbad93fcbc9...d62b5d5a17 14:05
Uh, the error was not even being able to install it. 14:06
moritz I don't know how Distribution::Builder searches for its perl :( 14:07
ugexe zef does that search
from the message just posted
github.com/ugexe/zef/blob/ef2157c7...1086-L1095
basically just shoves it into a `is native(...)` and sees if it works
use NativeCall; sub is_installed is native("perl") { }() 14:13

b-bar Might I ask why Raku has adopted 𝑒 (U+1D452) as the Unicode symbol for natural exponent? 14:49
According to the Unicode standard, U+1D452 has no special meaning[1], rather U+2147 (ⅇ) may represent natural exponent[2].

vrurg b-bar: 1D452 𝑒 Mathematical Italic Small E – I think 'mathematical' is the answer. 14:52
b-bar: and for 2147 the comment says: "_sometimes_ used for the natural exponent" 14:53
14:54 masak_ is now known as masak
b-bar Thank you @vrurg. But if the word "mathematical" is the key, wouldn't the appropriate symbol for pi be U+1D70B instead of U+03C0? 15:03
vrurg b-bar: good point. I think it can be an alias. But then again, for 03c0 it is also clearly stated in the comment: "math constant 3.141592..." 15:07
I think 1D70B can be made an alias. I also like the look of it more than 03C0. :) 15:09

spydox hi 17:42
sjn of course, feel free to ask anything about Raku :) 17:43
spydox Im trying to get started. I wrote a little helloworld.pl and tried run in comma.. All I get is unexpected EOF. It does run at the linux prompt. I *think* it thinks Im trying to run a "prolog" file .pl ? 17:47
17:47 clarjon1 joined
spydox it runs /usr/bin/swipl -t halt -q /home/me/CommaProjects/one/two.pl 17:48
seems like it SHJOULD run like /usr/bin/perl6 ....
I went thru every comma menu I dont see where it determines the compiler based on file type
I even tried a she-bang which was ignored 17:49
17:52 justsomeguy joined
MasterDuke well, .pl isn't recommended for raku scripts, you could try .raku 17:52
spydox wilco, Im on it! ty
sjn yeah, .pl is traditionally perl5 scripts; we used .pl6 before the name change, today it's .raku as MasterDuke says 17:56

spydox Raku v2019.11
its odd if I say RUN the only thing there is edit config
and if I go in there all my files are under "prolog" 20:48
yet a bunch of sources show up on the left..
if I do + on config, all the files are under "Prolog" 20:50
evem though there is no prol;og in the disk path 20:51
Altai-man spydox, can you show a screenshot? 20:54
spydox ok
Uploaded file: uploads.kiwiirc.com/files/726b6007.../posed.png 21:00
my first file was a .pl I guess it thinks this is a prolog project! 21:02
Altai-man spydox, no, I don't think so. can't you select "Raku" in "Add New Configuration"? Then you can specify a script to run and run it using the SDK you specified in Project Settings. 21:05
spydox if I do that it says UNEXPECTED EOF and it tries to run it as PROLOG 21:06
let me try again
Altai-man spydox, are you using standalone Comma or a plugin for IntelliJ? 21:07
spydox standalone in ubuntu
hello 21:08

THANKS sir much better
Altai-man spydox, and you have prolog plugin installed?
