I completely agree. The current situation is quite confusing.

File IO for the JS backend on node

You can clone it, change the nimble file (lower the nim version number) then, "nimble develop" the repo and try to import it. I guess most people just leave the minimum nim requirements as nimble generates it on the module init

How to make Nim more popular

Seeing how much IoT devices and "smart" home devices are getting so popular, Nim would be a far better option than Arduino's C/C++... I'm currently using MicroPython on a NodeMCU, primarily because it was easy to install with LOTS of documentation. I looked for Nim support first but the document

Does your project _[really](https://forum.nim-lang.org/postActivity.xml#really) need at least Nim 1.4.4? I'm running Nim 1.3.5...

File IO for the JS backend on node

For the JS backend when running under nodejs, is there a module for File/Stream IO (maybe wrapping nodejs' [FS module](https://nodejs.org/docs/latest-v0.10.x/api/fs.html))? Sorry to ask this, maybe I overlooked something basic, but I couldn't find anything in the Nim doco about it...

Idiomatic way to run a process in the background and close it when appropriate?

How does Nim ARC/ORC compare to Rust?

On the subject of "no refcount", I have a slightly tangential question... Strings and seqs in Nim are refs (with refcounts, albeit with copy semantics). As discussed in different threads, including [Multi-threaded features needed for Server](https://forum.nim-lang.org/t/7751) it is often desirab

nim-1.4.6_x64.zip/bin/nimble.exe reports as Trojan:Win32/Zpevdo.B

I guess the reason of these false-positives. Nim is rather popular among malware authors. Because it can produce very compact binary code, and because AST fully exposed via macros provides great code obfuscation capabilities to them. VirusTotal is a dumb piece of crap. All it does is just signa

1.4.6 works fine for me on windows...but I don't run finish.exe. I just extract the zip and add the dir to my PATH.

Idiomatic way to run a process in the background and close it when appropriate?

I'd like to spawn a process and run it in the background. I'd also like it to be closed when and if the process finishes executing. I looked through osproc's functions, but I can't figure out what is the most idiomatic way to do this. Also, I'd like the call to block until it spawns the process,

learn Nim regular expressions - regex, re , NRE

I think it would be inconsistent to mark `re` as deprecated and advise to use `regex` instead, while `re` is in the standard library and `regex` is not. If `regex` is now the right choice, the first thing to do is to add it in the standard library. Deprecation of `re` could follow.

Maybe it would worth to add `UPDATE: deprecated, use regex instead" to the top of `std/re` and `std/nre` documentation pages.

learn Nim regular expressions - regex, re , NRE

@didlybom1h , what languages add regex to the core / stdlib? But I guess even if there are languages do this - the next question is - would it be the right thing to do? I was learning Ruby and Python before - they both must import regex... There is probably a good reason for this behavior.

@Araq, thanks for the clear answer. This is something I’ve wondered myself in the past too. Are there any plans to bring the regex into the stdlib?

How to make Nim more popular

I'm new to Nim, but I think one possible direction is microcontrollers. Nim has a unique feature: compiling to C. As far as I know only a few modern languages have this feature, and among them Nim is the most active one. People working on microcontrollers use assembly before, and they use C now

Hi, As someone who just recently discovered Nim, I can recap what made me learn more about it: 1) Someone must mention it somewhere _outside_ its realm (Hacker News, Reddit, YouTube...). ✅ If no one talks about it, people will never know. It's important to write more blog posts, comment on va

Yes, this is a long list, but these are mostly drafted tasks. I will look at them later. As regards old code, you are right, but I updated it and replaced it in some rare cases. For now, all examples in the main tasks run with Nim version 1.4, at least until letter Y (letter Z is in progress).

How does Nim ARC/ORC compare to Rust?

I might be wrong here, please correct me if so, but: I think that equivalent code written in Rust and Nim would generally result in similar or even equivalent code that calls destructors and does not increase or decrease reference counts. Code that would actually modify reference counts in Nim

Overridable operator precedence

I know we're all used to operator precedence from elementary school and in programming languages, but beyond the very basic rules, most people find them very confusing -- especially with semantics vs syntax (e.g., many people assume << in C has the same precedence as * because they are both mult

How does Nim ARC/ORC compare to Rust?

In reality Swift, C++, Nim and Rust all work very similarly. At the same time there are big differences in the details. Rust also uses a garbage collection system based on reference counting ... ;-) Yes, really. It uses 1-bit reference counts under the covers and full reference counts for `Rc`
