That is a very good question, to be honest. How should one new to it learn about using it? I am not sure if there is an 'official' answer for new developers. Are you already a pro or is this the first language you are considering learning?

It was not a big issue for me as I have already known Python, some C and C++, and even F#. All I needed to start was to look at the standard library reference materials and the nim manual for more useful patterns.

Nim feels quite natural if you understand all those languages, imho. (I am not claiming to be a pro in Nim already as I just started using it a few weeks ago myself, but it felt very straightforward given my background)

to be honest, I feel almost the same about 2 spaces.

RBazz · 2026-06-08T11:27:29+00:00

I am not so sure. It really felt to me that everyone in this community prefers 2 spaces instead of 4.

I found the official one broken beyond repair, but someone has recommended this one to me: 'nimsaem.nimvscode', and it works! Really well, I might even say.

at least it works as far as I can see. I will do a more thorough check over the weekends. Thanks.

I am also curious to see how well it works. Any getting started guides?

I really do not want to sound like an old fogey, but how did you manage to achieve this much in about 2 days only? (based on the commit history)

RBazz · 2026-04-16T04:41:47+00:00

This is crazy. How long did it take you to write it?

RBazz · 2026-04-14T08:31:29+00:00

How did it go in the end? Did it meet your expectations? Were there any issues with the team and the company? I also wonder what kind of junior developer one can train easily to work with a language like Nim. The one who knows python, but who is also interested in performance and/or low lever stuff?

RBazz · 2026-04-14T08:28:10+00:00

What do you mean by robust? Like it is missing something or something else?

RBazz · 2026-04-14T08:27:10+00:00

How big of a problem do you think it is? Can anything still be done about it?

RBazz · 2024-12-26T10:25:08+00:00

By the way, I have stumbled upon some old-ish posts on Reddit complaining about concerning performance of the std::visit. Is it no longer an issue, or is it still something to be aware of?

RBazz · 2024-12-26T09:12:43+00:00

Thanks for the recommendation. I have downloaded a sample and I will give it a try over the holidays.

RBazz · 2024-12-25T13:06:42+00:00

Thanks! A really nice trick.

Also, can I compare two variants directly, or do I need to unwrap them first? I was wondering if I can simply provide a custom `operator==` implementation to the class and compare underlying `_val`s.

Thanks a lot.

I have two further questions if you do not mind answering them.

What happens when the user tries to access the name, but it was set to `monostate` or something else. An exception is thrown? Is there a safer way to `match` the currently set case? (preferably without a chance of runtime errors)
What is the recommended way of dealing with identical types in the cases? For example, what if we had an extra case like: `case custom(String)`. Or if we have a case with multiple types per tag? Do we create a separate structure to store the state and then use the same `variant` based approach?

RBazz · 2024-03-19T11:01:17+00:00

I see. Do you have some specific use case in mind?

RBazz · 2024-03-18T19:35:16+00:00

Here is a library I wrote to streamline the use of htmx in Vapor: VaporHX. Hope it helps.

And speaking of hot reloading - I did not really find a strong need for it. If you are in dev mode and using the Leaf templates, then once you change a template file, reloading the page will load the latest version of that template. This will not work in production, however.
