How to implement a generic arbitrary node-graph with unknown number of generic types?

Idea: Ultimately an "observer" is a callback so use closures or `std / tasks` for type erasure.

How to implement a generic arbitrary node-graph with unknown number of generic types?

Its good to know that the TS approach appears to be mostly a stopgap measure. However, the problem with RxJava is that it relies on generic methods, which I recall nim having issues with, so that approach is kind of dead in the water.

Help storing *reference* instead of copy in an object constructor.

1. pointer in Thing, var param (drawback: you have to make sure that the pointer stays valid): type Thing = object list: ptr seq[int] proc initThing(list: var seq[int]): Thing = result.list = list.addr Run 2. ref original

Help storing *reference* instead of copy in an object constructor.

Nim has no mechanism to safely reference a value type, as such you need to raise the `original` to a `ref seq[int]` like so var original = new seq[int] original[] = @[1, 2, 3, 4, 5] type Thing = object # I would like `list` to be set to a *reference *of `or

Help storing *reference* instead of copy in an object constructor.

How can I change **initThing** so that it stores in **list** a _reference_ to **original** so that when **original** is changed, **list** reflects the change. The current code just makes a copy :-( var original = @[1, 2, 3, 4, 5] type Thing = object # I would

Compilation Problem: "Error: cannot open C:\..\..\..\lib\system.nim"

Windows Defender is disabled, but this post did lead me down the right rabbit-hole, however. Thanks for that! :) I figured out my VPN is doing it. x.x Thank you. I'm now going to try to build my "Hello, World!" app.

How to implement a generic arbitrary node-graph with unknown number of generic types?

Related: Looking at docs for other Rx implementations for statically typed languages, e.g. RxJava and RxSwift, `pipe` doesn't seem to be in the picture, but `Transformer` and `compose` are a thing i

Compilation Problem: "Error: cannot open C:\..\..\..\lib\system.nim"

As stated in the subject line of this thread, I'm having trouble with compiling. Upon receiving this error, I browsed my nim-2.0.4_x64 folder only to discover that I have no lib directory. How do I get this directory? Also, I did notice a separate issue... I'm on Windows 11 and also have had so

How to implement a generic arbitrary node-graph with unknown number of generic types?

Heyho, I've been playing around with implementing reactivex (or rather expanding an existing lib to more fully implement reactivex), which is a lib to implement reactive programming, aka observables, subjects etc. . This allows you to make values depend on one another via a push instead of a pul

Nim on the go: Smartphone, termux and ... "no" docs.

The doc generator has an option to ouput [pdf](https://nim-lang.github.io/Nim/docgen.html#document-types-latex) files. Arch for example, used to generate them by default, but now it only installs the .md files under /usr/share/nim/doc/ . Which is another option I guess if you have a markdown re

You can install [devdocs.io](https://devdocs.io/nim/) as a Progressive Web App in your phone's browser. I've tried it in firefox for Android, but chromium-based browsers should also work. It does work offline, just note that you should "enable" a documentation first and then download it from op

Please review my types: ref object or plain object

I did have terrible performance issues related to the seq being copied when stored as a temp variable in a function scope. Thinking back on it, the problem there might have been that I used let while I should have used var. I suspected as much with the direct result assignment. (hence the commen

Please review my types: ref object or plain object

Where you used `ref` and where not seems ok as far as I can tell. However, usually you start with the non-ref version and then only if either performance is bad (copies) or else the logic requires shared mutable state to work properly things are changed to `ref`. `result.headPose = state.riderH
