Array Difference

Yesterday i was not able to find a proc for the array difference known from other languages like Ruby. I think I was searching for it already five years ago when I was new to Nim. It is available maybe with a different name already? As we use & for concatenation of sequences, using `-` from Rub

Might there be a better `dotOperators` design?

You might be onto something. Working through a bunch of examples of it working and also acting poorly will help test whether it's a good idea. Generalizations that reduce the number of rules in a language are typically a very welcome thing, fewer concepts more leverage. One way to do that is the

What is happening under the hood of "cast" function ?

I have a section about cast and type conversion in the Nim for kids book: Have you missed it, is it unclear?

Thanks :). The answer for both questions - because of simplicity. Proper JS packager like WebPack would be a better option but it would require more code to write and maintain. Websockets are also better, but require to write and maintain more code - on the client - to handle reconnections and

Neat stuff! And thanks for making the accompanying video. Looks like you're using deno to build out the JS too. If I may ask, what are the advantages of using Deno in this context? Regarding the nim part - is the plan eventually to incorporate some Websockets tech? Lots of those new HTML-on-the

Might there be a better `dotOperators` design?

Hey guys, I've been using the `dotOperators` feature since I started my game engine project 2 years ago. I use it to interface with C++ libraries, and for the most part it works amazingly. Being able to implicitly generate Nim bindings to a C++ library as you use it in your code is sick, IMO. I

Yeah I guess that was a bad example. But quitting from outside of a main still presents an problem.

Library for making lightweight Electron-like HTML/JS GUI applications

Finally I've had the time to make another release! Neel v0.3.0 Updates: * added ability to call JavaScript anywhere within a procedure freely/multiple times via `callJs` macro * added ability for `callJs` macro to be used in your other modules procedures * removed the need for procedures

Yes- this can be mitigated by using Neel lol

Multi-threaded features needed for Server

well 1) looks like a bug in your application to me. use valgrind or do a code review. 2) unsure - for me it was easy (but that's my subjective opinion). I developed some pooling utility years ago. Just look at how it was done. Originally developed with Ni

What is happening under the hood of "cast" function ?

Typically when you cast a variable to another it runs a procedure to convert it to the given type, since most types differ in their underlying bit representation. For instance `10.3.int` the `int(float)` conversion truncates the decimals. Now you also have a bit for bit `cast` which is `cast[in

Multi-threaded features needed for Server

I tried to [create Web Framework in Nim](https://forum.nim-lang.org/t/7749), and think there are some things that could be improved. 1) Errors in multi-threading mode Sometimes server crawhes with `SIGABRT pointer being freed was not allocated` or `SIGSEGV: Illegal storage access.` or hangs and

What is happening under the hood of "cast" function ?

Hi all, Almost all programming languages i met are using "cast" function to convert data types. I wonder what is happening under the hood of this so called "cast" function. I am sorry if i misuse the word function here. can anyone could explain it ? Thanks in advance.
