Novice parallelization question

It is not efficient to accomplish this task in the browser. The JS method for handling threads is by using workers, and even if it is possible to abstract over it, the cost will be too high.

Cheap exceptions, opinionated error handling

This looks like the complete opposite approach used by Zig. It's limited, and I don't like that. I'd rather go with the Zig approach—an enum that grows at compile time, without the Rust problem of converting results.

Which IDE to use in 2024?

Helix is quite good and easy to set up. The only problem is that I couldn't get it working with Nim.

get object field by variable

It should be possible to use macro magic to do that though.

Would Nim modules or available Nim web frameworks suffice for an e-commerce back-end?

Can you tell me more about the "problems" with async? As much as I dislike closures, that is not a problem in itself.

Hexagonal Architecture, Domain Driven Design, and Event Sourcing in Nim

This is not related. I've seen this pattern many times at work, and I really can't figure it out. Why is this happening? I may be missing something... proc credit*(self: WalletDomain, walletId: UUID, transactionId: string, coins: int): Wallet = try: result = self

9999999999999999.0 – 9999999999999998.0

it works with decimal but not with floats import decimal/decimal let a = newDecimal(".0") let b = newDecimal("9998.0") echo a - b Run

Sum types, 2024 variant

This is great! I've been waiting for something like this for a long time.

Nimforum custom theme

Too much freedom is a curse. The outcome it would achieve can be attained by using a client-side extension like Stylus. This dark theme is awesome, by the way.

Ideas about strings

Good enough for me! I hope we can have more control over lifetimes in the future.

How to prevent nim language server plugin from spawning multiple instances of nimsuggest

If you are using vscode, try add this line on you `settings.json`: `"nim.project": ["./src/main.nim"],` It solves the spawning problem and also the extreme cpu usage.

unsure about lifetime-tracking hooks

I'm trying to understand how the [lifetime-tracking hooks](https://nim-lang.github.io/Nim/destructors.html) work, but I'm not sure if I'm doing it correctly. The code below is an implementation of a slab (an array with reusable slots). It is almost an exact copy of the [example](https://nim-lan

Rc[T] implementation

type Rc[T] = object data: ptr T refs: ptr int proc rc[T](value: sink T): Rc[T] = result.data = cast[ptr T](alloc(sizeof(T))) copyMem(result.data, addr value, sizeof(T)) result.refs = cast[ptr int](alloc(sizeof(int))) result.refs[] = 1

converter not working unless I explicitly use it

I have a converter, from `proc(Request, string)` to `proc(Request)`, but the compiler refuses to accept it unless I explicitly call it. The code below works fine, but if I remove `.toRequestHandler()` it won't compile. What am I doing wrong? import mummy, mummy/routers pro

Thanks man, that's what I need.

Any way to prevent GC from collecting some values?

I need to pass some data to an external env as a pointer and use this pointer later, but GC will collect this value since there is no ref.

If anyone have the same problem in the future (download big files), here is my solution: It's a simple and single purpose script to download files (no proxy or redirect support).

How to copy dir using nimscript?

Learning threads

Can anyone tell me what am I missing here? I'm trying to learn about nim types and threads. I made this small example and theoretically it should work. The output is: Thread started! Input: 1 Handling command... Result sent back. Thread stopped! Run Th

could not load: lua(|5.1|5.0).dll

I created a lua lib using nim but only works if I put the lua dll in the same dir as the lib. I'm not embedding lua. Any ideas about how to solve this? If I remove the dll I get the error `could not load: lua(|5.1|5.0).dll`.

Problem with --threads:on

I tried without nimble, using this line `nim c --colors:on --path:C:\Users\psore\.nimble\pkgs\lua-1.0 -o:.\bin\server.exe .\src\main.nim` to compile my server, this will compile the binary and I can run int with no problems, but if I include `--threads:on` and compile it, will run and close imm

Problem with --threads:on

This is really strange and disappointing, with a `nim.cfg` inside `src` folder with just `--threads:on` inside I can, inside my "main" nim file have this line `var thread: Thread[int]`, and it will compile but the "Hello World!" message won't appear. If I rename the `nim.cfg` to `package_name.cf

Problem with --threads:on

[nim.cfg](https://i.imgur.com/U5IwpEO.png) [package_name.cfg](https://i.imgur.com/WSse4IT.png) Two prints showing the result, as you can see the `.cfg` file is inside the `src` folder.

Problem with --threads:on

I create a new project and did all those steps again, the problem seem to be with the `nim.cfg`, if I'm using `package_name.cfg` it works properly but if I'm using `nim.cfg` it doesn't works.

Problem with --threads:on

I'm using `nimble run` and I have a `nim.cfg` at `src` folder with `--threads:on` inside.
