warning_unreachable_code hello

warning_unreachable_code how are you doing

warning_unreachable_code yeah i was warning then i switched to error

warning_unreachable_code i'm doing fine

TheIbraDev Write some tests

TheIbraDev How have you been Mario man?

NakorBlue oh right im subbed, i was like wait i dont see adds

TheIbraDev latest streams have been during Nighttime here

warning_unreachable_code do you still update your blog about performance

warning_unreachable_code i forgot about your site

TheIbraDev Just follow modern tech and let it crash

TheIbraDev link it

SpirodonFL https://enlightenedprogramming.com/

Rei Ayanami how are you doing?

TheIbraDev I think i even inserted my email there. Spiro hasn’t sold my info yet

TheIbraDev (yet)

Rei Ayanami can i ask you why you use one monitor? and why your laptop one?

Rei Ayanami did you see the new open ai model?

ghostm4gic hello mr mario

Moldy Apple Odin + your mom = viking babies

kelyje you can use Overview as a reference

kelyje https://odin-lang.org/docs/overview/

Tazdij Nice, using odin :)

Tazdij Really? For me I just download it, extract it, and then add that into my .bashrc it all works. I am on debian 12 though

Tazdij You already have it working here though, so no need

olavostauros who is talking? spiro, spiro minus minus or spiro69?

olavostauros chat is kinda ded

ghostm4gic map

olavostauros instanfce

olavostauros instance

Tazdij I like using zone or region

kelyje Location?

olavostauros what about instance?

olavostauros omg spiro is ignoring my suggestion TearGlove

rook_uwu world, level, sub levels.

ghostm4gic level assume progress to higher one

olavostauros wet_water/solid_land

ghostm4gic zone/region assumes all are equal

Tazdij @olavostauros Instance is already something in programming with a meaning, I avoid it to reduce possibly conflating them

ghostm4gic the only correct answer is map :)

olavostauros @Tazdij gotcha

olavostauros a clusterfuck

olavostauros it's a good idea, a clusterfuck

LaughinPanda Destination?

kelyje let's vote ))

Tazdij I like zone and region, as they don't carry and additional meaning or implicit properties

olavostauros a zone inside a zone

Tazdij Any*

olavostauros we must go deeper

rook_uwu world region east, west, north, south. then zones in regions

ghostm4gic you can see why programmers are so bad at naming

Tazdij Also with zone it is easy to have subzones too

olavostauros clustecrfuck!

olavostauros the nerdzone

ghostm4gic so your ocean will be a zone, and city will be a zone and that's confusing

ghostm4gic but both are maps

LaughinPanda Region and Port.

olavostauros a zone of a zone, within a zone, that is a zone within itself

olavostauros shore?

olavostauros shore/port

olavostauros shore/port/sea

Tazdij @ghost a map is an illustration of the topography of a region ;)

ghostm4gic right, and that's why it matches both

ghostm4gic and you can call ocean a zone, and call port a port

LaughinPanda There's no factions and territories in your game?

olavostauros can I pet the dog in your game?

ghostm4gic you just need different names for ocean, port and both

Tazdij In a data structure though, is there any reason to store it any different than each other? A region/zone/map should be nesting in a hierarchy with each node having a type field

SneakyFoxtrot Yo!

NakorBlue thats it im review bombing this game now.

Tazdij Rofl, honestly doesn't matter, usually just a personal preference that is blown out of proportion

Tazdij Dynamic arrays are contiguous but might be relocated is resized

Tazdij If resized*

Tazdij Im pretty sure, Odin zero initializes arrays without initial values defined

Tazdij you can do multiple return values

kelyje but you can return two values

Tazdij so it is a limitation of the WASM?

Owencodes Oi

ghostm4gic exception

TheIbraDev Gotta go sleep, have s nice stream @spirodonfl !

Owencodes spirod1Hi

del_cx How you finding Odin so far? I picked it up again few months ago too

Rei Ayanami do you use wls on windows? why?

Tazdij Oh, this a function being exported to use in JS. I have never tried it with an exported function

ghostm4gic you can't throw exception?

Lafolie_ spirod1Hihi spirod1Hihi spirod1Hihi spirod1Hihi spirod1Hihi spirod1Hihi spirod1Hihi

Lafolie_ Odin has multiple returns

Tazdij it did seem to work correctly when they were internal functions without the need to interop with js

Lafolie_ ^int

GhostSpeedRunner hello

Tazdij Why doesn't returning a struct work?

GhostSpeedRunner im ur 36th subscriber

Lafolie_ just return false in the bool return

Lafolie_ Oh you can't because of the WASM thing

Lafolie_ You can't use a union?

Lafolie_ You gotta predeclare the union

Lafolie_ static type innit

Lafolie_ Just setup the union in the function body

Lafolie_ You didn't change the body

Tazdij I think you need declare a variable of type Value, and then set it, and return it

Tazdij in the function body

Lafolie_ in the get_value proc set the return value to either false or the array element

Lafolie_ v : Value = some_array[index]

Tazdij should only declare v once

Lafolie_ right but you are always return the second one now lol

Lafolie_ huh. Maybe wasm doesn't support unions

Lafolie_ oh, get rid of the v: Value line between the proc and union

Lafolie_ You're shadowing so maybe that is screwy?

Tazdij line 32, you still have a global v. but I don't know if that is an issue

Lafolie_ So the best way I can think to solve this is a switch

Tazdij does it return an u16 if you give it a valid argument?

Lafolie_ oh wait, you'd still need two procs

Tazdij ok, so then it is not liking the union?

Tazdij because it should be copying the value itself into the return

Lafolie_ No, that's for checking the union tag

Tazdij can you export the Value definition?

Lafolie_ You don't need an enum for that because Odin has tagged unions

Lafolie_ Can wasm read a struct?

Tazdij something seems odd, because this sort of thing works with emscripten and C

del_cx Odin macros to generate glue?

del_cx (comp type stuff)

Tazdij Oh, so you are trying to do this without the runtime library odin has, to make all the language features work?

Lafolie_ I'm pretty sure I read somewhere that Odin has some extra stuff for the wasm build

Lafolie_ like a lib or something

Tazdij odin-dev-2024-03\vendor\wasm\js

Lafolie_ Check the source for vendor:wasm

Tazdij no, on your local file system

kelyje https://github.com/odin-lang/Odin/tree/master/vendor/wasm

Tazdij wherever you installed odin at

Tazdij oh hey, looks like it is in the repo too

Tazdij this is the glue code to make it all work

Tazdij I suppose you will just need to write your code in a very particular way, to work within the confines of wasm

Protonmat You have come to the Odin side

Protonmat Im Glad

del_cx val :: 25

del_cx this is const

Lafolie_ constants are untyped compile-time symbols in Odin

Lafolie_ The only way I can think of really solving this is manually checking the array len before you call get_value_of...

Protonmat You could use a Enum for errors

kelyje let him cook

del_cx If its all single threaded, could you have global variable which is flipped on error, c style?

del_cx e.g. when error happened read this register to find out which value you hit

del_cx error you hit*

del_cx CheckLastError()

del_cx And in JS you just want to make sure that error list length is always 0?

del_cx if get last error returns non 0 we have an error, so it give you ID of latest error instead.

Lafolie_ Might be worth your time to ask on the Odin discord about this. Finding it hard to believe wasm has this limitation

Lafolie_ well Odin errors are just bools

Lafolie_ There's no exceptions

ghostm4gic @Lafolie_ but you have panic right

ghostm4gic so what was wrong with panic(EXCEEDED_LENGTH)

ghostm4gic -1

Owencodes @Rei Ayanami theres nothing wrong with using wls on windows I use it and ik several other devs who do it its a very popular dev enviroment

ghostm4gic i meant 0 -1 should give you max

ghostm4gic if unsigned

Lafolie_ @ghostm4gic No, Odin has multiple reterns. So the odiom is to return (value: int, ok: bool)

Lafolie_ Bill's rule of thumb is "you made the mess, so you clean it up"

ghostm4gic 0xFFFF

Lafolie_ but I have no clue about anything wasm

Lafolie_ Yeah you have to be explicit about casting in Odin

Lafolie_ panic ends execution

Lafolie_ Try assert

ghostm4gic but would you continue execution if exceeded length

Owencodes dad me and lafo miss u :D

ᎮᏒᎥᎷᏋ Spiro!!

ghostm4gic but why would

Owencodes spirod1Hearts spirod1WorkingHard spirod1Lurk

Lafolie_ assert instead of panic

Lafolie_ but it would finish anyways, hrm

ghostm4gic assert(false)

ghostm4gic and end execution

ghostm4gic cause there's something wrong with your math

ghostm4gic and you need to fix your code

ghostm4gic if would be wrong if you go over array length

ghostm4gic depends if you do that or not

ghostm4gic yes, we check it, but this code is wrong if he hits it

Lafolie_ Yeah I really think checking length before calling is the simplest way

ghostm4gic so no reason to run it

Lafolie_ Yeah

Lafolie_ Does the built-in bounds checking not apply to wasm?

ghostm4gic but if you're outside of scope then no need to process that on js side

ghostm4gic js code is wrong

ghostm4gic you just need exception / panic and that's it

Lafolie_ Odin has bounds check. Maybe the runtime.js file has something

Lafolie_ runtime.bounds_check_error

ghostm4gic and that was great

ghostm4gic yes, that's a different case and more complicated

ghostm4gic then you need some error

ghostm4gic right i understand

Lafolie_ okay

Lafolie_ So how about this

Lafolie_ assert(len(arr) < index, "You're out of bounds, dummy")

ᎮᏒᎥᎷᏋ how did you learn coding?

Lafolie_ Replace the if with the assert

Lafolie_ Get rid of the if block

Lafolie_ Yeah a union would be nice here

Lafolie_ or a struct

omnifidus Your "TWITCH ADS ARE PLAYING" message did not go away after the ads were over.

Tazdij lol, stream video thinks there are still ads

rvIceBreaker @SpirodonFL fix your overlay ya dingus

rvIceBreaker endstream

rvIceBreaker laser focus

Tazdij no reason to break your flow state

Owencodes hey spiro made more progress on my personal site :)

Owencodes spirod1Lurk spirod1Hearts spirod1Lurk

Owencodes :)

TravisVroman Oh, didn't realize you were streaming. Also Odin? 9 e's. How are you liking it?

TravisVroman In particular how do you like it as compared to Zig?

TravisVroman That's interesting considering how much you love Zig

TravisVroman Does it win out over C?

Hasen Judi Odin FTW

TravisVroman -WASTED-

TravisVroman I'd jump in and try it if I didn't already have my entire engine written in C LUL

Lafolie_ vendor

thefallaway Hello

Tazdij Odin is easily my favorite language of the c-like replacements

Tazdij super good math lib

TravisVroman Does it have a comptime type deal?

TravisVroman Like compile time string hashing?

Lafolie_ when blocks are compile time

Tazdij @TravisVroman no, nothing like a Zig comptime

thefallaway Wait vulkan and ratlib in core? That's crazy

ghostm4gic so what makes it better than Zig?

TravisVroman Vulkan is in core Dahek

Tazdij #1 the syntax of zig make my eyes hurt, and odin's doesn't

Lafolie_ Bill and Andrew are good friends

TravisVroman That's a good thing imo

Lafolie_ Yeah Bill's position is 'BDFL'

TravisVroman If you don't like it, fork it

LaughinPanda But, you're Canadian you have no guns to stick to...

TravisVroman C++ *ahem*

Tazdij Odin is very inspired by the book, "Algorithms + Data Structures = Programs"

TravisVroman Nobody realized that the name of C++ is really just an iterator for bloated bullshi

Tazdij which makes me like it too

Tschieses the core-lib sounds too good to be true - nice * ,*

Tazdij Also there is a huge application in production which is written in odin, so that is at least proof of its ability and utility

TravisVroman Swizzle for shizzle?

TravisVroman I've always thought swizzling should be extended to other languages than shader languages

omnifidus @TravisVroman I don't think there is a bit-swizzle in Odin. :=)

thefallaway But how far have you cooked?

TravisVroman @omnifidus Fair, but any kind of swizzling is a step in the right direction imo

thefallaway I mean it looks kind of straight forward

Lafolie_ You can swizzle arrays

Lafolie_ not sure about bits

thefallaway "Just go" go = golang Kappa

TravisVroman *Entity Complication System

TravisVroman Aw, bollocks. Poor timing on my part lol

NakorBlue thought it was 24 hours

Lafolie_ thanks for the stream <3

Tschieses take care everyone :3 /

SpirodonFL Join our discord and get inspired! https://discord.gg/7ZrQHjUsJ4

Tschieses thanks for the nudge to Odin - will take look at it!

thefallaway Yes

Tschieses sounds fun Kappa

TravisVroman Have a good one
