Which tools do you use to code in Nim?

VSCode with nimsaem’s plugin. I wish it worked better though :/ As for libraries, Arraymancer is the one I probably use the most. It’s awesome!

Which tools do you use to code in Nim?

I use `nano` and `nim` on a terminal, usually [Termux](https://github.com/termux/termux-app). Sometimes I use another text editor in graphic interface. I also use a script (made by myself) to get the generated C code.

Which tools do you use to code in Nim?

choosenim + nim + nimble + vim + nimlsp That's my basic setup, I also have the zah/nim plugin for Vim to give me syntax highlighting. As for libraries it highly depends on what I'm doing. However the simplicity of termstyles means that I often include it. And of course Futhark has become more

peekChar() on stdin

Very new to Nim, so apologies if this is a stupid question. Consider the following code: import std/streams var s = stdin.newFileStream() echo "peek: ", s.peekChar() echo "read: ", s.readChar() Run Assuming I input `1` to stdin, I expect the output to

Mindset Nim

The problem is that inim fails for anything beyond the simplest examples and it is quite slow. It is great that it exists, and it is nice for learning, but it is far from what you can get in languages like Python, Matlab or Julia.

I'm surprised I don't see any mention of the INim REPL. You can `nimble insta inim` and have a functional CLI REPL for testing small code snippets. I use it a lot when I want to test the behavior of a single line, and I used it quite a bit when I was first learning. It's not something that can m

You are missing the `ok` in the success path: proc getValue(node: ValuesNode, key: Bytes32) : Result[Bytes32, string] = if node.values[key[^1]] == nil: err("Value not found") else: ok(cast[Bytes32](node.values[key[^1]])) Run (took the liberty

Need help writing a helper function?

Ah, you're trying to apply a python workflow to a compiled language like nim. Basically ideally you'd want to have runtime introspection like go into a repl and get a list of all methods defined for a type. This is sadly not quite possible given how nim works in general, due to being a more low

Using Result library

I think it is unlikely to find other solutions (there are indeed other means to do it, but I think all of them work in similar ways as the Results lib), since Nim is a very strong typed language. You can also use `throw newException(...)` to throw exceptions, but I guess it is not what you want.

Need help writing a helper function?

Actually I think there are not really such solutions. However, if you use Editor support, for example the VSCode extension by nimseam, you can type `"string".` and see all methods available in the Editor completement. As far as I know, this is powered by the tool nimsuggest under the hook.

Compatible enough as it's possible to write code that works with both versions.

If it was trivial to do and/or I knew exactly how to do it, I would have written one by now, heh (I have multiple toy REPLs, but they all have certain problems). For an example of a REPL of a compiled language - C++ - you can check out cling: It effectively uses the

Nim version 2.0.0 is here

How is backward compatibility with Nim 1.x source code? If one wanted to package Nim 2 for a GNU/Linux distro, should there be a separate `nim2` package (which might conflict with the `nim` package) or is it fine to treat Nim 2.0 as a straight upgrade?

Need help writing a helper function?

Just browse the official documentation and focus on these modules for `seq`: system.nim, sequtils.nim, algorithm.nim Or come up with the **verb** you need to use, why do you care if e.g. `deduplicate` exists for `seq` when you don't need to deduplicate seq entries...

Depending on how you build the VM it actually supports calling into native code. There is also a callback mechanism for extensibility not unlike how Python does it.

The reason for this is that scanning through the std documentation seems to take too much time. I just want to set up some basic data and move on from the data, find the associated function, select the possible function, then see the function docstring and examples.

Yes, I assumed everyone was on the same page. This is not the C/C++ backend. But it doesnt mean you can call those functions, you could: * Compile the compiler with `importc` support * Statically bind wrappers-hooks (like the compiler does) * Dynamically bind wrappers (like NUE does) For

Conceptually, how would a REPL for the C backend even work? It would have to work with C imo since otherwise the output of the REPL wouldn't be representative of what you could expect if you compiled it yourself. Doesn't that make the inim approach the only feasible one (You actually treat it a

Mindset Nim

When people talk about a Nim REPL they usually mean a REPL for the C/C++ backend. The Nim VM can only evaluate pure Nim code, so anything that ends up calling some wrapped C code / shared library doesn't work. In practice that means the Nim VM cannot be used for anything non trivial. (There's al
