| voidzero | What's a good book on Raku? Not a total Perl beginner, but still a newbie somewhat. | 14:32 | |
| librasteve | personally I like think raku (althought this teats you like a beginner to all programming, it is easy to speed read and get a very well organised into the main features imo) | 14:33 | |
| greenteapress.com/wp/think-perl-6/ | 14:34 | ||
| ^^ freudian slip? | |||
| otherwise, the docs.raku.org pages have sectional intro material | 14:36 | ||
| so after reading raku 101, then just read the tutorials that take your fancy | 14:37 | ||
| docs.raku.org/language/classtut, docs.raku.org/language/grammar_tutorial, docs.raku.org/language/list, docs.raku.org/language/hashmap, docs.raku.org/language/control | 14:39 | ||
| ^ maybe these | 14:40 | ||
| voidzero | great, librasteve thanks! | 14:48 | |
| rcmlz | I originally got interested in Raku because of concurrency: docs.raku.org/language/concurrency, also good to know (to avoid reinventing the wheel) what is already build in Arrays/List docs.raku.org/type/List plus hyper/race from docs.raku.org/type/Iterable | ||
| antononcube | @voidzero In case your prefer recipe or case studies books: 1. "Raku Fundamentals: A Primer with Examples, Projects, and Case Studies", www.amazon.com/Raku-Fundamentals-E...1484261089 2."Raku Recipes: A Problem-Solution Approach", www.amazon.com/Raku-Recipes-Proble...1484262573 | 15:24 | |
| voidzero | I enjoy the 'Learning Perl (8th edition)' and 'Intermediate Perl' books a lot | 15:28 | |
| doing the exercises is very useful | 15:29 | ||
| antononcube | @voidzero If you want to "graduate" from using 3d or 4th generation programming languages into 21st century AI-infused programming experience, then read: 1. "Workflows with LLM functions", rakuforprediction.wordpress.com/20...functions/ and 2. "Number guessing games: PaLM vs ChatGPT", | 15:31 | |
| rakuforprediction.wordpress.com/20...s-chatgpt/ | |||
| voidzero | I'm not sure I'm ready for that yet LOL | 15:32 | |
| hey what's your discord link so I can just join that | |||
| antononcube | @voidzero I am not sure what is "a Discord link"? Of Raku's discussion group at Discord? | 15:34 | |
| voidzero | yes, please :) I assume that there are more channels than just the two I'm in via LibreIRC | ||
| antononcube | This should work: discord.com/invite/VzYpdQ6 . See here: raku.org/community/ . | 15:35 | |
| realvoidzero | Much better, thanks | 15:38 | |

| jgaz | Is there a streightforward way to compare an smaller array against a larger array and get the offset of any match? That is @small would be a part of @large having the exact same elements in the exact same sequence but at some unknown index? | 21:11 | |
| ab5tract | jgaz: good question. unfortunately nothing comes to mind besides doing it in a "traditional" algorithm | 21:18 | |
| though I imagine someone smarter than me could come up with some way to do it via stringification and regexes | 21:19 | ||

| ab5tract | m: my @a = 1, 3, 5; my @b = 1, 8, 9, 0, 1, 3, 5, 6; my $offset; for @b.kv -> $i, $v { next unless $v == @a[0] || all(@b[$i + 0..^(+@a)] == @a); $offset = $i }; say $offset | 21:29 | |
| camelia? | 21:30 | ||
| anyway, the above seems to work jgaz ^^ | |||
| actually can get rid of the first part of the unless | |||
| scratch that... | 21:31 | ||
| you need the first part too :) | |||
| m: say "hello" | |||
| jgaz | Let me play with it and see if it works for me. | 21:32 | |
| ab5tract | not sure what's gone wrong with our butterfly :( | ||
| I've violated my own principle for using unless here, though (that is, never use unless with more than a single condition) | 21:34 | ||
| camelia | 4 | 21:38 | |
| hello | |||
| ab5tract | o/ camelia! :) | ||
| m: my @a = 1, 3, 5; my @b = 1, 3, 6, 0, 1, 3, 5, 8; my $offset; for @b.kv -> $i, $v { next unless $v == @a[0] || all(@b[$i + 0..^(+@a)] == @a); $offset = $i }; say $offset | 21:41 | ||
| camelia | 4 | ||
| ab5tract | doh | ||
| m: my @a = 1, 3, 5; my @b = 1, 3, 6, 0, 1, 3, 5, 8, 9; my $offset; for @b.kv -> $i, $v { if $v == @a[0] && all(@b[$i + 0..^(+@a)]) == @a { $offset = $i; } }; say $offset | 21:42 | ||
| camelia | 4 | ||
| ab5tract | ^^ jgaz, a less confusing edition, perhaps. note that if you want it to only pick up the first existence of @a in @b, you will want to add a last in that if block | 21:43 | |
| wambash | m:my @a := 1, 3, 5; my @b := 1, 8, 9, 0, 1, 3, 5, 6;@b.rotor( +@a => -(@a-1) ).grep( * eqv @a, :k).say | 21:47 | |
| Raku eval | (4) | ||
| ab5tract | wambash: nice one! | 21:49 | |
| nemokosch | "create a sequence of shifting windows in @b that have the size of @a, and look up the index where the window matches @a exactly" | ||
| possibly multiple indices | 21:50 | ||
| I figured it might be a bit dense to read if you are unfamiliar with the principle ^^ | |||
| @wambash what are you using Raku for, if I may? | 21:52 | ||
| wambash | mainly for fun, lately I'm using Raku at university for some scripts for (static) malware analysis using fuzzy sets. | 22:05 | |
| ab5tract | wambash: that sounds like some interesting work | 22:06 | |
| Marcel249 | Hi everyone, I am obsessed writing code in Raku, it's such a cool language. Why can't I find a good Raku Wallpaper? | ||
| ab5tract | Marcel249: hmmm, we don't seem to have one of those, do we | 22:09 | |
| nemokosch | are you a professor? | 22:10 | |
| ab5tract | Marcel249: somewhere there should be a camelia in SVG that you could use to create one | 22:17 | |
| wambash | senior lecturer | 22:19 | |
| nemokosch | will do š¤ | 22:25 | |
