| lizmat | it takes the first with the if-clause matching | 13:11 | |
| so if you change the order of the candidates, you should be fine | 13:12 | ||
| habere-et-disper | That's the issue. I'm trying a declarative programming approach and I don't want the order to matter. | 13:16 | |
| nemokosch | That's not the only issue really | 13:17 | |
| The resolution order seems to be obscure and underspecified | 13:18 | ||
| lizmat | gist.github.com/lizmat/d63d0ed8e4c...37fa0a6813 | 13:29 | |
| habere-et-disper ^^ | |||
| habere-et-disper | Wow, thanks. (y) So if I grok this now then as long as the predicates are mutually exclusive we can forgo candidate order. | 13:41 | |
| lizmat | yup | ||
| otherwise order becomes meaningful | |||
| habere-et-disper | Lesson learnt. Merci ! | ||
| kdon | hello, i would like learn what can be done with raku languaje | 22:01 | |
| lakmatiol | string processing of most kinds can be expressed really nicely. | 23:04 | |
| 24 Sep 2023 | |||
| antononcube | Raku's string processing nicely completes (or integrates with) Large Language Model (LLM) workflows. | 01:13 | |
| snonux | I like to use Raku for small command line utilities and also for one-off-quick-n-dirty-getting-things-done-scripts. Not to say that Raku can also be used for larger applications, but I personally didn't do that (yet). | 12:40 | |
| scullucs | m: my $b = Blob.new(1, 2, 3); say $b.WHAT; say "{$b.WHAT}" # Why does the interpolated one fail? | 14:44 | |
| Raku eval | (Blob) Use of uninitialized value of type Blob in string context. Methods .^name, .raku, .gist, or .say can be used to stringify it to something meaningful. in block <unit> at main.raku line 1 | ||
| lizmat | m: my $b = Blob.new(1, 2, 3); say $b.WHAT; say "{$b.WHAT.gist}" | 15:33 | |
| camelia | (Blob) (Blob) |
||
| lizmat | scullucs: interpolation calls .Str on the expression, say calls .gist on the expression | ||
| lucs | lizmat: Hmm... Okay, thanks. | 15:39 | |

| lizmat | and yet another Rakudo Weekly News hits the Net: rakudoweekly.blog/2023/09/25/2023-...eleaseses/ | 12:01 | |
| habere-et-disper | We can repeat a string or a list with "x" or "xx". How do we repeat a statement ? Just use postfix "for" ? | 22:41 | |
| 26 Sep 2023 | |||
| nemokosch | this is not Ruby 😄 | 00:00 | |
| but actually xx thunks | |||
| so it will execute an expression as many times | |||
| m: rand() xx 5 andthen .say | |||
| Raku eval | Exit code: 1 ===SORRY!=== Error while compiling /home/glot/main.raku Unsupported use of rand(). In Raku please use: rand. at /home/glot/main.raku:1 ------> rand⏏() xx 5 andthen .say | ||
| nemokosch | whatever the reason is | 00:01 | |
| m: rand xx 5 andthen .say | |||
| Raku eval | (0.07748747360451047 0.20944011451510647 0.01756085583672984 0.2818930280640839 0.8926975957918685) | ||
| habere-et-disper | Thanks -- I did not know this! :) | 00:22 | |
| scullucs | Depending on what one wants, the postfix "for" could be used: | 01:30 | |
| m: say rand for ^5 | 01:31 | ||

| rcmlz | Is it possible to test for Constrains? #!/usr/bin/env raku subset Allowed-Returns of UInt where * ∈ 1..10; sub some-function(Int $a where * mod 2, UInt $b where { ($a + $b) mod 2 }, --> Allowed-Returns ) { $a + $b } use Test; dies-ok some-function(2,7); I tried dies-ok, thrws-like and it does not work. gist.github.com/rcmlz/e4532b0c80f1...30b69a0470 Thank | 08:09 | |
| you. | |||
| Nahita | hi, dies-ok et al. takes a code block to call for you, you shouldn't already call it | 08:37 | |
| like dies-ok { f() } | |||
| also there is the %% operator for even disibility, so maybe * !%% 2 is clearer than * mod 2 | 08:38 | ||
| so in your case it tries to call what the call some-function(...) returned; albeit since some-function(...) errs, it doesn't reach the dies-ok at all | 08:39 | ||
| rcmlz | Thank you @Nahita - I did not read the documentation carefully enough. Now it works like a charm! Very nice feature! | 08:56 | |
| stanrifkin | Is there an overview of the new features of v6.e? | 20:18 | |
| nemokosch | this is a good question. I don't think there is an explicit compiled list - it's not yet released, for what it's worth, and I wouldn't say there is a final vision of what it will contain | 20:21 | |
| stanrifkin | thank you | 20:22 | |
| nemokosch | there are some changes in the core, that's the simpler part and that could really be collected. Some of these are kind of "bug fixes". | 20:24 | |
| better complex support for certain math operations, the new snip method for cutting a list/sequence, the snitch method for conveniently executing a callback on a value while returning it nevertheless to allow for chaining... supposedly there should be value type lists and maps but I cannot see that one yet | 20:27 | ||
| nested slices coming from arrays... | 20:28 | ||
| either way, the big one is RakuAST which is the main focus of the whole v6.e | 20:29 | ||
| basically a high-level in-language representation of Raku code that supposedly compiler frontends could produce and compiler backends could consume | 20:30 | ||
| this should make user-space code generation much simpler and more efficient | 20:31 | ||
| stanrifkin | found here something raku-advent.blog/2021/12/25/future...-language/ | 20:32 | |
