Yeah.. that came up in a private conversation as the easiest next step for global "workspaces" like the R repl has. There' s still perhaps some trickiness if any objects contain pointers to other objects since pointers are not "fat" (or encoded as offsets to some base address to be "re-linked at

Does the stdlib HCR work at all? I tested the program in the [docs](https://nim-lang.org/docs/hcr.html) (making sure that the logic was in a separate file), and on 2.0.2 and 2.0.4 it produced bad codegen. On 1.16.14 it compiled, but it didn't actually work.

You could write an object with `system.copyMem` but then you would have an issue with non shallow datatypes (like strings), so i think the best would be to serialize your data first. For example with

An LSP can do pretty much anything an extension can with little to no fidelity difference. The difficulty in implementation is another matter, I've wasted a lot of cycles on trying to improve the LSP but it's a pain to get a productive test setup going and even if you do the inability to kill t

You're probably right. I was using the Saem nim vscode extension, because I had wanted to add some features and the typescript was't getting frequently updated and I wanted to work with nim. @Saem lists "Extract most functionality into an LSP (check existing one)" on the readme. So there is des

Why spending on this or that extension when improving would make most IDEs compatible with Nim?

NIM IDE

I don't get your point - install count (or download count) almost never correlates with software quality, it rather shows software popularity, and kosz extension has 48k installs because it has been around for much longer. Nowadays it's not maintained while the saem extension is, so it actually

The typescript VS Code Nim plugin has 48k installs vs 3k for the saem Nim version. Are you recommending that people use the Nim version because its better, or because you hope it becomes better in the future with support?

If you so like PyCharm perhaps you will stick with the Nim plugin for it (from Intelli JDEA creators)

There are two Nim extensions for VSCode. One written in typescript and not frequently updated, and one written in Nim with frequent updates. I highly recommend using and contributing to the pure Nim one: . You can also use the codelldb plugin for debugging. T

Nim used to have its own IDE, Aporia: . Trust me when I say: it's better to spend time perfecting a VS Code extension rather than a standalone IDE.

that would be time and resource expensive and could lead the developer team attention away from nim development, maybe a community solution would be good, if i'm not wrong a nim ide similar to vim already exists

Hi Nim guys! In my opinion NIM is one of the best language around. Point. It should have its own IDE. Commercial solution like Embarcadero Delphi offers a free community edition. Also R Studio offers a free edition for R. Are project like Aporia and similar still in development? I write this j

The only issue I have with inim is that it recompiles everything each time a command is sent. If you're using any randomization in your variables, you'll get different variables everytime you have a new input. Booo

Thanks Araq, looks like it'll have to be HCR for now. For the life of me I couldn't get arraymancer to work with `nim secret` and deep learning stuff was originally what I intended on making the notebook IDE for. As for your recommendation, I'll definitely head in that direction at a later time

`nim js` is pretty fast, enough to use for a normal REPL or scripting purposes, though it's not exactly a substitute for all the C bindings.

There is a patch for enabling the FFI with Nim's VM or you can use hot-code-reloading. I think neither approaches are that good, I encourage you to look into solutions that patch Nim's allocator to be support "shared" memory and patch the C(++) codegen so that globals are accessed via an indirec
