korvo I would like to install Humming-Bird using zef. However, this causes Cro::TLS to be installed, which fails with the error, "Cannot locate native library 'libssl.so': libssl.so: cannot open shared object file: No such file or directory" 06:28
This can be minimized to the inability to $(zef install OpenSSL), which also fails. Now, to be fair, I don't have a /usr/lib/libssl.so but I'm willing to show zef where it is. Are there docs that I can read on this topic? 06:30
Alternatively, I don't actually need TLS support right now. Is there a way to indicate that TLS is optional and doesn't have to be installed?

tadzik you may be able to point it to the right libssl with LD_LIBRARY_PATH 06:46
(that's an env variable, nothing zef-specific)

korvo tadzik: Looking at the Build.rakumod there is an OPENSSL_PREFIX envvar which does the trick. Thanks for the hint. 06:51

disbot6 <simon_sibl> is there a way to import a module as another name ? 07:42
<simon_sibl> also if I use a module, for example sibl::Foo which export sub greet, how come greet works but sibl::Foo::greet does not work ? 07:46
07:52 arkiuat joined
disbot6 <simon_sibl> I have to do our sub ... if I wanna use the syntax <some>::<module>::subname() ? 07:56
07:57 arkiuat left
disbot6 <simon_sibl> that means that if I do require on a module, which use is export and not our sub then I cannot use any of the subroutines from the module ? 08:04

ab5tract Export doesn’t change the scope of th function, it just adds things to the importer’s scope 09:22
09:22 sibl joined
ab5tract So you still need to declare as ‘our sub greet’ to be able to call it with ::Bar::greet 09:23
You cannot change the name of an imported module but you can create a new name referencing the imported module by creating a constant 09:24
09:24 arkiuat left
ab5tract You can even create this constant/alternative name in the EXPORT routine. Terminal::Print does this 09:25

korvo rcmlz: Nice. I'm on NixOS too. It looks like zef doesn't have an offline installer mode, so I can't really prepare an environment with packages in the Nix store, but your trick looks good for setting up a temporary environment. 16:35
16:37 arkiuat joined
timo you can just run `zef install .` inside of an extracted distribution, though if you don't have the dependencies already installed, it will still try to find it on the 'net 16:40
korvo Which is precisely what one may not do during a Nix build. 16:41

disbot6 <_ccubed> Of what use are loop labels if they can't be used with respect to an outer loop? 16:55
<_ccubed> The only examples in the doc would work the same if last LABEL or next LABEL dropped the LABEL. 16:56
<_ccubed> So I checked and in fact you can't use a last FOO do exit an outer loop labeled FOO. 16:57
lizmat m: FOO: loop { loop { last FOO } }; say "outered" # seems to work ok ? 17:00

lizmat can you gist the code that shows the issue ?
disbot6 <_ccubed> I've been doing it in the REPL, so give me a few minutes
<aruniecrisps> lizmat: oh! okay then no worries, I was just curious because I wanted to learn a little bit more about the MoarVM internals and see how it all works 17:03
lizmat _ccubed ah, the REPL 17:04
make sure that the first "FOO: loop {" is on one line in the REPL, then it should be ok 17:05

disbot6 <_ccubed> Well I did a small example in a script and it seems to work, but examples in the docs that would work the same without the feature being explained are not helpful. 17:16

[Coke] I am confused by your syntax also. 17:42
disbot6 <_ccubed> Using the exact syntax in the documentation for the toggle method
17:44 dakkar left
disbot6 <_ccubed> I copied and pasted the example without the ':off', then ran it again with the ':off'. 17:44
<_ccubed> There's a space between the '.toggle:' and the '.off' 17:46
timo evalable6: gist.githubusercontent.com/coke/21...1/foo.raku
evalable6 timo, Successfully fetched the code from the provided URL
does this work?
timo [Coke]: the discord-irc-bridge turned a multi-line message into a single line, there was a newline between the &is-prime and (0 1 2 3 6 7) there 17:47
disbot6 <_ccubed> evalable6: 15/6
<_ccubed> With respect to the documentation, what would help me greatly is description of what various syntax characters mean in different contexts. 17:52
<_ccubed> What the heck is the asterisk doing there? 17:53
<_ccubed> What water is that colon carrying here?
[Coke] docs.raku.org/type/Any#method_toggle ? 17:54
disbot6 <_ccubed> yes
[Coke] ok, that doesn't quite match the sample there, but the `.toggle:` - the list after the : are the arguments to the toggle method. 17:56
disbot6 <_ccubed> Try the 1st example then add an ':off:' to it
[Coke] toggle is taking Callables; you can specify a sub, or a block or a WhateverCode - the `* < 4` is a bit of code that can be invoked, and will return true if the argument passed is less than 4.
disbot6 <_ccubed> Yes, I understand that much 17:57
[Coke] :off is a named parameter to the method.
(different use of colon)
disbot6 <_ccubed> Why, with ':off' is anything printed before 4?
<_ccubed> got that backwards 17:58
<_ccubed> er, wrong
<_ccubed> why is 0 printed but 2 is not
[Coke] ah, I see that your example in IRC is probably missing some #'s to mark things as comments. 17:59
Sure it looked fine on discord.
so just this one?: 18:00
m: say ^10 .toggle: * < 4, * %% 2, &is-prime
camelia (0 1 2 3 6 7)
[Coke] I don't see an example on the page that prints 0 but not 2. 18:01
I see one that prints 2 but not 0? 18:02
disbot6 <_ccubed> No, take the example you just gave to Camelia, and insert a ':off,' before the '* < 4'
<_ccubed> m:say 15/6 18:03
[Coke] m: say ^10 .toggle: :off, * < 4, * %% 2, &is-prime
camelia (0 2 3 4 5 6 7 8 9)
[Coke] that prints 0 & 2.
disbot6 <_ccubed> I can see the 0, but there shouldn't be a toggle until you get to 4, so what happened to the 1? 18:04
<_ccubed> No wait the * %% 2 toggles when you get to 2 18:05
<_ccubed> Does the order of the callables matter? 18:06
<_ccubed> The document suggests that it does,
<_ccubed> What's the use case for .toggle? 18:07
timo one example is when you have line-based input and you want to grep groups of lines that have a starting and an ending marker of some kind 18:09
m: say <( a b c d ) x y ( 1 2 3 ) 9>.toggle('(', ')')
camelia No such method 'CALL-ME' for string '('
in block <unit> at <tmp> line 1
timo m: say <( a b c d ) x y ( 1 2 3 ) 9>.toggle(* eq '(', * eq ')') 18:10
camelia (( ) x y ( 1 2 3 ) 9)
timo m: say <( a b c d ) x y ( 1 2 3 ) 9>.toggle(|(* eq '(', * eq ')') xx *) 18:11
camelia (( ) ))
timo not sure how best to do an infinite toggle like the ff operator would do
disbot6 <_ccubed> Ok timo, I've got to go now. Thanks for the help. I'd like to get deeper into Raku. I've used it successfully a couple of times for Project Euler, projecteuler.net/ 18:13
[Coke] I am trying to follow the logic for adding the :off to the sample, and honestly it makes my brain hurt. 18:14
starts off, then 0 is < 4 which matches, but that changes the state to on, which should move it to the next callable. 1 isn't %% 2, so that should fail, which should change the state back to off, which should go to the next callable. 2 IS prime, so it should turn back on... and then should stay with is-prime since it's the last callable. but then why is it printing 4, 6, 8? 18:15
I tried replacing the callables with blocks that include "say" statements so we can see them being invoked, but no love. 18:16
ah, because I did it wrong... 18:17
m: say ^10 .toggle: :off, {note "A$_"; $_ < 4}, {note "B$_"; $_ %% 2}, {note "C$_"; $_.is-prime} 18:18

[Coke] ah, so we ran out of Callables, and the *switch stays in the current position* 18:20
which is in the docs, but it helped to see it in action there.
it's not that it stays on the last Callable, which was my initial mis-read 18:21
timo m: say <( a b c d ) x y ( 1 2 3 ) 9>.grep({ '(' ff ')' }) 18:22
camelia (( a b c d ) ( 1 2 3 ))
timo m: say <( a b c d ) x y ( 1 2 3 ) 9>.grep({ '(' ^ff^ ')' }) # doesn't include the parens when using ^
camelia (a b c d 1 2 3)
timo grep ff is easier to use when you want the testers to always toggle 18:23
[Coke] mmm 18:24
I wonder if "code golf" is the use case for toggle. :P
