| disbot4 | <jubilatious1_98524> @voldenet The size is a hard-sell if you're trying to get schools to try installing Raku on a RaspberryPi... . | 08:18 | |
| Voldenet | different hardware, different tradeoffs | 08:24 | |
| disbot4 | <jubilatious1_98524> @voldenet prove to me Rakudo loads, compiles, and runs on a RaspberryPi. If it doesn't then it's a limitation of the Raku language, not a tradeoff. | 08:30 | |
| Voldenet | hmm I could actually check if it builds on some arm soc | 08:49 | |
| I think that even 512 rpi would be able to run raku and that is the absolutely smallest one | 09:08 | ||

| lizmat | tbrowder: the self.a calls the method a on the invocant: that's an infinite loop in your program | 11:51 | |

| camelia | Cannot resolve caller is(Int:D); none of these signatures matches: (Mu $got, Mu:U $expected, $desc = "") (Mu $got, Mu:D $expected, $desc = "") in block <unit> at <tmp> line 1 |

| SmokeMachine | tbrowder: the only way to call a attribute (called a) is with $!a… self.a and $.a calls methods… not attributes… | 12:24 | |
|
12:25
arkiuat left
|
|||
| SmokeMachine | has $.a do not mean it’s creating an attribute $.a… but it means that it’s creating a attribute $!a and a method a… | 12:25 | |
| lizmat | tbrowder: what SmokeMachine said :-) | 12:28 | |
| SmokeMachine | tbrowder: So, when you do: has $.a; method a {…} its overriding the method that would be created by the declaration $.a… so when inside of method a you do self.a, it will call itself again… entering an infinite loop… | 12:33 | |
| tbrowder: I just realised I may have misinterpreted your question… are you saying that the compiler should give an error when a method is overriding a method created by the attribute declaration? | 12:35 | ||
|
12:37
arkiuat joined
|
|||
| SmokeMachine | (By overriding I mean: if I remember it well, if the class already have a method with the attribute’s name, it doesn’t even tries to create the accessor method) | 12:40 | |
| (I only read that part of the code when I start developing Red… too long ago… I’m not sure anymore…) | |||

| camelia | 3 | ||
| arkiuat | there's the numification to 3 | ||
| sorry about all that. I'm still a novice at irssi and apparently I did something that switched windows between #raku-doc and #raku while I was trying to ask that question | |||
| the question went to #raku-doc! which doesn't have Camelia. So here is the question: | 17:51 | ||
| disbot4 | <librasteve> 42 | ||
| arkiuat | The documentation for ~~ says "see ACCEPTS documentation for the type on the right-hand side of the operator". StrDistance doesn't have a documented ACCEPTS method, and neither does its parent Cool, and the behavior documented for the ACCEPTS method of Any (Cool's parent class) is not what I see going on here. So which ACCEPTS method is getting called by ~~ here? | ||
| librasteve_ | good question | 17:53 | |
| arkiuat | the thing that stringifies to 'new string' and numifies to 3 is a StrDistance object | ||
| I've always found Raku's ~~ operator a little confusing, and this is one reason why! | 17:54 | ||
| librasteve_ | i guess(!) that `~~ tr/a/b/` is a syntax sugar for trans(a,b) | 17:57 | |
| docs.raku.org/routine/trans#(Str)_method_trans | |||

| librasteve_ | not quite sure how to ground that out (hopes people with “actual knowledge” will chime in) | 17:59 | |
| arkiuat | thanks, that's helpful. So I guess in this case, it's class Code's ACCEPTS method that is getting called, which makes sense | ||

| melezhik | after some recent feedback I decided to update sparrowhub.io - so to make it official Sparrow project web site, de-facto it was, I just now am making this clear, comments, feedback are welcome, thanks. It's WIP | 18:00 | |
| librasteve_ | cool! | 18:01 | |
| arkiuat | the doco for ACCEPT in class Code says that ACCEPTS (and therefore ~~) just returns the result of the called code | ||

| librasteve_ | please can you post the code (snippet) that makes a StrDistance | 18:07 | |
| oh sorry - just found it - my guess #1 wrong, please ignore | 18:09 | ||
| docs.raku.org/language/operators#t...literation | 18:10 | ||
| arkiuat | right, that's the page whence I copied out the snippets I started with | 18:11 | |
| librasteve_ | lol | 18:12 | |
| arkiuat | I still think you led me in the right direction though, and that it is the ACCEPTS method from class Code that is getting called here | ||

| wayland | .tell melezhik Thanks for the Sparrow website. I've updated my Pathways of Entry article to link to it. | 23:46 | |
| tellable6 | wayland, I'll pass your message to melezhik | ||
| wayland | .tell melezhik What your page is missing is an explanation of why one would want to use Sparrow rather than eg. running commands in bash ( sparrowhub.io/examples would be shorter as a bash command). Does it run on multiple servers? Is it so that you can ensure state on them? You may be having the same problem as Raku: too many features highlight none. But your website should start with a list of the use cases. HTH, | 23:51 | |
