| El_Che++ | |||
| El_Che | lizmat: I should cloudsmith make to pay me. With every new release they add the needed distro because I ping them | 10:15 | |
| :) | |||
| they lacked ubuntu jammy (next stable) so the upload of ubuntu-devel packages failed | |||
| lizmat | I see... | 10:16 | |
| El_Che | lizmat: I had to do a weird workaround, though: | ||
| # Workaround for github.com/rakudo/rakudo/issues/1515 | |||
| mkdir -p $INSTALL_ROOT/share/perl6/site/short $INSTALL_ROOT/share/perl6/vendor/short | |||
| touch $INSTALL_ROOT/share/perl6/site/short/.keep $INSTALL_ROOT/share/perl6/vendor/short/.keep | |||
| the packager I use does not handle empty dirs well in debs | |||
| and for one reason or the other rakudo started supplying 2 empty dirs a few releases ago | 10:17 | ||
| lizmat | have you made an issue for this particular issue ? | 10:18 | |
| El_Che | yeah, it's in the paste | ||
| lizmat | the empty dirs issue ? | 10:20 | |
| El_Che | yes | ||
| lizmat | nxadm commented 16 seconds ago | 10:21 | |
| yeah, now :-) | |||
| El_Che | no, no, that's how I worked around it, not the issue itself | 10:22 | |

| Altai-man | well, the original Camelia of course, but don't know about others. They look super cool though. | 15:39 | |

| Anton Antonov | @Altai-man Thanks for the links! I am writing about connecting Mathematica and Raku. For the Raku-mode cells in Mathematica I use the stylized icon raw.githubusercontent.com/uzluisf/...-logo1.png . (Rotated 30 degrees.) But I wanted to refer to more "generic" and well know source of Raku icons. | 15:48 | |
| Altai-man | for the docs website I used this: raku-infra-fsn1-01.rakulang.site:10...loured.png and IMO it looks 1)recognizable; 2)more stylish, the original is somewhere in the marketing repo. | 15:50 | |
| I like the hex icon you're using now a lot too, IMO that's an example of an icon one can show to people outside of community without them making faces. | 15:51 | ||
| Anton Antonov | I tried to use a smaller version that icon to indicate Raku cells, but that icon has too many details. | 15:52 | |
| Altai-man | hmm, how small do you need it to be? | ||
| in Comma we use 13x13, which is fairly small, and it works kinda alright. | 15:53 | ||
| Anton Antonov | @Altai-man Yes -- thank you for that feedback! | ||
| There is a question of how well it fits with the icons of other language cells in Mathematica. I will post example within 2 min. | 15:54 | ||
|

| Here is an example of Raku and other languages cells in a Mathematica notebook: imgur.com/NvT40r0 | 16:04 | ||
| Altai-man | hmm, I don't see anything criminal, but maybe it can be resized better, now it looks blurry. | 16:07 | |
|
16:08
holyghost left
|
|||
| Anton Antonov | Yeah, it does, I have to tweak the Mathematica code for those cells some more. I think the icons used by WRI are from vectorized drawings (not images.) | 16:09 | |
| WRI == Wolfram Research, Inc. (Makers of Mathematica) | |||
| BTW, as background cell color I used background color in the input/output cells in the documentation. (E.g. here: docs.raku.org/language/objects .) | 16:12 | ||

| lucs | m: 'x' ~~ Any && print "Why does this match?" | 16:17 | |
| camelia | Why does this match? | ||
| Altai-man | lucs, because 'x' is Str and Str is Any. | 16:18 | |
| maybe you meant this: | |||
| m: 'x' ~~ Any:U && print "Why does this wait you don't see me..." | |||
| camelia | ( no output ) | ||
| Altai-man | ? | 16:19 | |
| lucs | Hmm... I'll think it over, thanks. | ||
| Altai-man | say: 'x'.^mro.say | ||
| oops | |||
| m: 'x'.^mro.say | |||
| camelia | ((Str) (Cool) (Any) (Mu)) | ||
| Altai-man | so it is an instance of Str, Cool, Any and Mu. | ||
| lucs | The context I'm seeing the "problem" is different, but your explanation should help me figure out what to do. | 16:20 | |
| Altai-man | lucs, what do you want to do in the first place? | 16:21 | |
| lucs | Let me beef up my example... | ||
| Altai-man | if you need an exact type check you can use =:= I think. | ||
| m: say Any =:= Any; say 'x' =:= Any; | |||
| camelia | True False |
||
| lucs | Turns out I'm calling a function that returns an array, and I want to see if some element appears in that array. | 16:26 | |
| But the returned array can look like (Any), and 'foo' ~~ @A matches in that case (which I don't want). | |||
| E | |||
| sorry | |||
| 'foo' ~~ any @A | |||
|

| lucs | (edited) But the returned array can look like (Any), and 'foo' ~~ any @A matches in that case (which I don't want). | 16:27 | |
| At least now I understand what's going on :) | |||
| Altai-man | is the function yours? | 16:28 | |
| lucs | No :( | ||
| Altai-man | if you can change it, why not return Empty... ah, I see | ||
| hmm | |||
|
16:29
statisfiable6 joined
|
|||
| Altai-man | maybe you want `'foo' (elem) @what-returned`? | 16:29 | |
| lucs | Oh, good idea. | ||
| Yeah, that works fine. | 16:30 | ||
| Thanks! | |||
| Altai-man | it's probably cheaper (?), but in any case it's less weird than using ~~ for membership check. | ||
| yw | |||
| lucs | "Weird" is in the eye of the more experienced developer ;) | 16:31 | |
| Altai-man | perhaps | ||
| lucs | The TIMTOWTDI can sometimes be misleading, ey. | 16:32 | |
| *eh | |||
| Altai-man | I mean, it's more specific and being more specific is good IMO. | ||
| lucs | Oh, I totally agree. | ||
| Altai-man | m: say 1 ~~ [1, 2, 3] | ||
| camelia | False | ||
| Altai-man | it doesn't work the usual way and then you need to do tricks with junctions | 16:33 | |
| but junctions are tricky | |||
| lucs | I'd just forgotten about (elem) and tried something I vaguely thought would work. | ||
| Altai-man | yup | ||
| lucs | It's good to screw up like that once in a while (not too often!), it can become a learning experience. | 16:34 | |

| spacekookie | I have a question about grammars (I'm pretty new to raku still so pls easy explanation :p) but why does my say line not print a hash with the two keys I provided? paste.rs/c7I.pl | 19:23 | |
|
19:24
jjido left
|

| spacekookie | It prints "(Any)" | 19:25 | |
| leah2 | so, the problem is TOP doesnt match due to the whitespace | 19:30 | |
| ugexe | because it should be e.g. `token TOP { <keyword> \s <payload> }` | ||
| leah2 | and then you want LineGrammar.parse(...).made | 19:31 | |
| Anton Antonov | @lizmant Will do -- thanks! | ||

| [Coke] sees "find element in returned list" and didn't see 'grep' suggested. huh | 20:00 | ||
| Anton Antonov | Is there named regexes for `\v` or `\n` ? (Like `<space>` for `\s`.) | 20:08 | |
| Or, probably it is more correctly to say ask: is there a predefined character class for vertical whitespaces? | 20:11 | ||

| okay i'm confused again. I'm trying to replicate the example in the "Action Objects" section and a bit confused by the message I get paste.rs/siB The error: No such method 'made' for invocant of type 'Array'. (in the TOP method) | 21:56 | ||
| moritz_ | `$<statement>` is an array because <statement> is inside a quantifier | 22:06 | |
| so you'd need something like method TOP($/) { make $/<statement>.map: *.made } | 22:07 | ||
