ray tracing. would that help with the maze solution? 00:11
intersections of rays in a plane with known planar figures (curved or straight, connected or disconnected) 00:15

disbot7 <aruniecrisps> @jubilatious1_98524 here's what i wrote, note that it only works for one character glot.io/snippets/hea42gkiew 03:48
Voldenet sadly it's limited to what unicode knows to be decomposable 04:01
m: "ł".NFD.list[0].chr.say 04:02
camelia ł
Voldenet it's clearly l with a slash
disbot7 <aruniecrisps> @voldenet yeah I'm not sure why that is 04:06
<aruniecrisps> For my use case it works fine because that's just how the Indic languages work, they're all decomposable
Voldenet unicode in general loves theoretical linguistics, which is correct
but for practical ones you might want to use things like metacpan.org/pod/Text::Unidecode 04:07
though in general you can't translate unicode to ascii sadly, modules like above usually handle just a subset and do really wild stuff, like translating 十 to + 04:16
transliterating, even 04:17

guifa the L with stroke doesn't really decompose because there's no equivalent diacritic 05:09
the stroke combining diacritics aren't actually the same thing so it's not a decomposition candidate

disbot7 <antononcube> @tbrowder_04810 Here is an example of my description of doing "maze with words": 14:43

<antononcube> BTW, the hexagonal maze makes "2026" look bullet ridden: 14:44

<jubilatious1_98524> ~ % raku -e ' say NFKD("ł").map: *.uniname.raku;' ("LATIN SMALL LETTER L WITH STROKE") 15:15
<jubilatious1_98524> @Voldenet The "ł" character doesn't appear to be de-composable. 15:17
<jubilatious1_98524> (...looks like @guifa chimed in already). 15:20

Voldenet jubilatious1_98524: I know and it's "theoretically correct" - it's different letter from l with a stroke 16:33
but if I wanted ascii representation, I would use l anyway
either way, it's just one example of how dumber replacement tables actually are better for the task 16:34
because unicode wasn't made for this
> role R[::T] { has %.h{T} }; class A does R[Str] {} 16:35
this suspiciously resembles github.com/rakudo/rakudo/issues/6056 - I bet it's similar to bug in instantiate_generic 16:36
m: role R[::T] { has %.h{T} }; # this is enough 16:37
camelia ( no output )
Voldenet …or not
nevermind, it's different after all
tbrowder what are you really trying to do with thy Unicode characters? why the need to deconstruct them? 18:21
Voldenet turn utf into ascii, it's a very common problem if you for example need to construct url out of text 18:32
or simply store ascii text in search, there's a lot of use cases for it

disbot7 <.landyacht.> Love these, it's difficult to find mazes that are somewhat of a challenge as an adult... used to draw them on the back of kids' menus when I was little, tried to make them as hard as I could :^) 19:43
<antononcube> Great! 🙂 19:45
<antononcube> @Rog You might like the "Applications" and "Neat examples" sections here: www.wolframcloud.com/obj/antononcu...Labyrinth/
<antononcube> I am not sure what Raku package should provied those random labyrinths / mazes. Maybe, something like "Acme::RandomMaze". 19:57
