johnjaye question. is there a reason that variable names cannot have dashes followed by numbers? i read this and found things like x-6 are not allowed as variables 02:22
ugexe it would be ambiguous with subtraction 02:29

ab5tract johnjaye: note that you can use single quotes in identifiers 08:39
I think that applies also to variable names, but alas my iPhone keyboard doesn’t seem to have a proper single quote to try it out with 08:40

tellable6 2025-10-09T03:54:47Z #raku <tonyo> librasteve: how long of a talk need it be?
lizmat simon_sibl one nit: is that how you spell dictionary ? :) but cool indeed :-) 09:12
librasteve_ m: my $o'dell = 42; say $o’dell; 09:13
camelia ===SORRY!=== Error while compiling <tmp>
Variable '$o' is not declared. Perhaps you forgot a 'sub' if this was
intended to be part of a signature?
at <tmp>:1
------> my $o'dell = 42; say <HERE>$o’dell;
librasteve_ my $o'dell = 42; say $o'dell; 09:14
m: my $o'dell = 42; say $o'dell;
camelia 42
lizmat yeah, the second ' was a 2019 RIGHT SINGLE QUOTATION MARK ’ 09:15
librasteve_ (turns out macOS terminal interprets “‘” differently to IRCcloud)
neat demo of why this feature should be avoided!
disbot5 <librasteve> @simon_sibl one neat trick with regex (and thus Grammars) is to use look ahead assertion to employ the built in raku syntax, for example 09:22
<librasteve> my regex number { \S+ #grab chars <?{ +"$/" ~~ Real }> #assert coerces via '+' to Real }
09:23 arkiuat joined
disbot5 <simon_sibl> lmaooo sorry xD native french xD 09:24
<simon_sibl> I will fix this xD
<simon_sibl> sorry I am probably tired, would that help making the grammar I made easier ? I try to keep it short, would that help while keeping it not "bloated" xD 09:27
Voldenet ' in variable names is cursed code - I once made a toy programming language that allowed spaces and tabs in variable names
it was horrible idea
09:28 arkiuat left
disbot5 <librasteve> Voldenet: amen to that - the only use case that I could imagine would be to have a single quote at the end such as my $a; my $a'; my $a''; (ie a prime, a douple prime) as in math / physics notation - but that is explicitly disallowed in raku identifiers anyway 09:29
Voldenet instead of a'' consider a" 09:30
disbot5 <librasteve> @simon_sibl - if you are looking for an Int, then standard regex digits (as you have) is definitely better - I was just mentionning in case you want to parse something like a Num or Rat 09:31
Voldenet but $a_ and $a__ is actually good replacement
disbot5 <librasteve> excellent point
lizmat I guess one of the reasons for allowing ' in identifiers is:
m: m: sub don't($a) { say "do not $a" }; don't "foo
camelia ===SORRY!=== Error while compiling <tmp>
Unable to parse expression in double quotes; couldn't find final '"' (corresponding starter was at line 1)
at <tmp>:1
------> on't($a) { say "do not $a" }; don't "foo<HERE><EOL>
expecting any of:
…
lizmat m: m: sub don't($a) { say "do not $a" }; don't "foo"
camelia do not foo
disbot5 <librasteve> .oO ... that makes (very limited) sense 09:32
<simon_sibl> silly quick question, how does zef/Rakuland find new raku module ? 09:39
<simon_sibl> or "how to submit a module"
<librasteve> you need "fez" for that 09:40
<librasteve> docs.raku.org/language/modules 09:41
<librasteve> raku.land/zef:tony-o/fez 09:42
<librasteve> also, many folk use App::Mi6 to automate release and change control 09:43
<librasteve> raku.land/zef:skaji/App::Mi6
<simon_sibl> thanks, I tried to upload the basic Bencode file xD lets see 09:47
Voldenet m: sub d'_'b($a) { say "♫⋆｡♪ ₊˚♬ﾟ.$a♫⋆｡♪ ₊˚♬ﾟ." }; d'_'b "foo" 09:54
camelia ♫⋆｡♪ ₊˚♬ﾟ.foo♫⋆｡♪ ₊˚♬ﾟ.

disbot5 <simon_sibl> well now I got a problem with Bencode and Grammar, how do I parse torrent file with raw bytes in it that arent utf8 ? I tried the latin-1 trick but it doesnt seem to solve the issue, it doesnt match anything when I try with latin-1 11:34
<simon_sibl> the code can be found here: raku.land/zef:4zv4l/Bencode / github.com/4zv4l/Raku-Bencode 11:40
11:44 arkiuat joined 11:49 arkiuat left
disbot5 <simon_sibl> yeah for some reason it reads too much (2 characters too much) when there is the bytes part (trying with Debian torrent netinstall file) 11:59

[Coke] (camelia stickers). I can help with that probably Q1 2025. (where's my UV printer, Bruce!?) 12:53
disbot5 <simon_sibl> let me try 12:55
<simon_sibl> not sure how tho, I do the encoding with latin-1, and I cant give a blob or buf to grammar.parse
<simon_sibl> I read the right amount of byte I guess (62640 so cannot count manually but Blob.bytes shows the same amount) 12:57
<simon_sibl> so I dont understand why it reads a bit too much 12:58

disbot5 <simon_sibl> if that helps for people to check: glot.io/snippets/hbvfzohnob 13:13
<simon_sibl> I added the link to the torrent file and to my lib (the lib code isnt necessary here, I took the code for the parser out)

disbot5 <.landyacht.> Is there any guidance for using NativeCall on Mac? I’m trying to get some code of mine portable, but Mac complains about libcrypto being loaded in an unsafe way. I can solve it by specifying the version the system has installed explicitly (e.g. is native(‘libcrypto.46’)) but that’s obviously not sustainable 17:38
<.landyacht.> My initial thought is a very early phaser to look in the system libraries path but I don’t know how viable or good that is… 17:40
<antononcube> @Rog I do all of my Raku-NativeCall project on macOs. See "Math::DistanceFunctions::Edit" or "Math::SparseMatrix::Native" .
<.landyacht.> I’ll take a look, thanks 17:41
<antononcube> I followed the setup (for NativeCall packages) by titsuki and bduggan. 17:42
<.landyacht.> Oh, is this using your own C code? 17:46
17:48 vasko4 left 17:49 vasko45 joined
disbot5 <antononcube> Yes. 17:49
<.landyacht.> Ah okay, mine is using whatever libcrypto is provided by the system, although maybe I could get around this issue by having my own C layer? Idk how much I like that idea though 17:51
<antononcube> The "Makefile.in" has to be changed accordingly. I am not sure about the C-libraries inclusions. I think I tried that without success with Apple's "Accelerate". 17:52
