Upcoming `Result` review - comments and thoughts welcome!

After many iterations and bug-fixes, we (Status) are finally moving to Nim 1.6 (where previously 1.2 was used for stability reasons) - in light of this, I've started thinking about reviewing [`Result`](https://github.com/arnetheduck/nim-result/) from the point of view of efficiency, ergonomics

Calling Nim proc from C and handling the cstring (char array) returned

cstrings are untraced pointers. They cannot hold the ownership of a Nim string. When you assign `"Hey there C code! " & $rand(100)` (a string as a temporary object) to `result` (a cstring), the `string`'s life ends because its reference count is reduced to zero and is not increased, and as a res

Nim in production #2: 100k+ WebSocket connections on one small VM, lots of CPU and RAM to spare

I want to **highlight** that this is based on the [mummy](https://github.com/guzba/mummy) webserver that does not use Nim's `asyncdispatch`, but instead uses OS threads, ORC memory management, and a custom HTTP parser. It's all forward-looking to Nim 2.0. It has a really cool model where all IO

Future of typing ?

While I like optionality and infer for all types, it may be too hard to implement, it's unrealistic. But what's definitely possible and annoys most is lack of auto types when **specifying it explicitly don 't contribute to readability or correctness** so those types are just annoyance and usele

Anyone tried GPT-4 for Nim?

Calling Nim proc from C and handling the cstring (char array) returned

proc gimme(): cstring {.exportc.} = result = "Hey there C code! " & $rand(100) Run is broken. Here is a sketch of a solution: proc gimme(): cstring {.exportc.} = let tmp = "Hey there C code! " & $rand(100) result = cast[cstring](malloc(tmp.le

Anyone tried GPT-4 for Nim?

Sorry to be a bit off topic, but as a guy who is not familiar with GPT, what does it? And how does it work for Nim?

Nim v2.0.0 RC2 is out

Is there something wrong with `sqlite3` and this release? I tried to compile with this last version and seemingly it's complain about the module not being found: Error: cannot open file: sqlite3 Run

Calling Nim proc from C and handling the cstring (char array) returned

I want to call a Nim proc from C which returns a cstring, the same as the "gimme" example at . I want to check that the way I am using the char array returned to C is sound. This is a minimal example of my current

Future of typing ?

In TS i started to use pattern like tihs: const create_api = (options) => { const dosth = () => xy const domore = () => { dosth(); dosth(); } return { dosth, domore } } It allows to reuse things from scope easily minimizing passing arguments. And from my point of view its fine if the co

Future of typing ?

"Overloading plus Hindley-Milner like type inference is NP-complete and Nim focuses on overloading." Thanks for explaining it, I always wondered what was the reason of the inference "lacking". Is there a paper/resource you can link where the relationship is explained in more detail? On the oth

Future of typing ?

Overloading plus Hindley-Milner like type inference is NP-complete and Nim focuses on overloading. I have never regretted this decision in my life. ;-) More type inference is not necessarily good: "I have to type less" has to be weighted against "error messages are more mysterious than ever". >

Future of typing ?

I wrote some simple code like this: var v = 100 proc build_fun(a: int): proc (): int = var b = 20 proc foo(): int = b = b + 1 result = a + b result = foo var f = build_fun(10) f2 = build_fun(

Nim in production #2: 100k+ WebSocket connections on one small VM, lots of CPU and RAM to spare

This is super encouraging to hear. I was really tempted to see if I could get away with putting some nim into production at work recently but I’m holding off for the moment. One thing I didn’t see last time I searched were nim libraries for open telemetry. If I can find the time I might try to
