Small libraries you'd like to see ported to Nim?

Thanks for the quick response, When I write things my aim is to be practical with high impact, so even though it can fail as you say for learning purposes, i aim for it to be functional. in other words, we want modern languages that are actively used. What languages would you suggest as input? D

Small libraries you'd like to see ported to Nim?

So... me and Claude, we're writing a transpiler. This is partly an experiment with AI, and partly a chance to finish an ambitious project i had a few years ago (which got to about 70-80% completion and took about 3-4 months -- it was a c# to nim transpiler using Roslyn) I will now tell you all

Claude 3.5 (Sonnet)

Just a note, for those not following the AI scene. Claude.ai have released a new model called Sonnet 3.5 Very very capable in terms of code writing. For example, I spoke to it about improving Nim's error messages and show me where they exist in the code, and it fetched github sources, took a loo

Raising the IC feature again

Hello, I would like to ask what is the current state of incremental compilation? Was it implemented while I was away ;-) Looking at github issues, it seems it is partially implemented? I asked 'Claude.ai' about further optimizations inline with nim's design philosophy (that is, not too crazy st

Why not use AI to create momentum in Nim?

Those numbers of course come from Hamas authorities, which is a genocidal terror organization. The worst estimates are 3 terrorists to 1 civilian, but no one really knows, and the IDF never hurts civilians for no reasons (so I assume the actual hurt are much much less). This is really off topic

Why not use AI to create momentum in Nim?

it's like a huge knowledge base without any ideas. when you state your intention and ideas, or tell it an example and to find similar themes, then it's working. I think it can save a lot of time, but you have to be the product manager, and do the proof-reading. it's verbose and you need to corre

Why not use AI to create momentum in Nim?

PS: Usually it may refuse to cooperate. for example, if you want to see prototype ideas for a military defense system that uses high speed drones to physically tackle a drone attack, (hey I'm from Israel, it's on our minds...) Then, you ask it about how to track thousands of flies simultaneously

hardware-software interaction in Nim

Hi guys, I have initial thoughts on connecting a small drone to a computer console-like system, programming in Nim, and sending messages to it, not via the hardware controller, but via the software. it could be several drones, maybe send them tasks to perform. From a software design perspective,

Wishlist: Ideal UI library for Nim

I'm sorry to state the obvious for everyone, in my opinion this is a huge task, and we don't really need a gui made from scratch especially for Nim. I applaud the effort of course, but we don't need it. We only need a library that is easy to get started with, non-friction, Nim way. It can simply

Wishlist: Ideal UI library for Nim

Nimx was nice, but lacked widgets. With most of the gui options, lack of widgets is the determining factor in abandoning it. I know it's hard work, but the user cannot be expected to write that code. There are also wrapped libs that aren't very nimish. So easy to get started, relatively nim way,

why use nim over c#?

I would have to disagree, OOP is very useful. designing with interfaces and classes or structs, encapsulates your data in one object, which is very useful for avoiding complexity down the road. The myriad design pattern, yes, they are confusing and sometimes lead to more confusion. But you can c

why use nim over c#?

With C# you have a ceiling of high-level code - a ceiling of abstraction, on the other side you have a floor you can't break - you cannot go too low-level either. In C# you will have to use reflection or annotations or something horrible as that, to go further, and it is really really really slo

Choosing Nim out of a crowded market for systems programming languages

I want to say that I have tried many languages, and came to understand that Nim is "future-proof", it can go down all the way, and go up all the way. So, very abstract because of macros, and very low level, because it compiles to c. performance was always good enough. memory use, had to be optim
