Wishlist: Ideal UI library for Nim

High quality software mostly have their own custom UI library, for example FL Studio or Blender. And modern consoomer UIs with their huge, gigantic butons made for touchscreens first look like crap. Especially on Linux, wether is Qt, Gtk, Wx, the buttons are huge and disproportional. If I woul

Some of Nim's convention needs to change in order for it to succeed

"The lack of namespaces in Nim" is like saying "The lack of pointers in C"

realloc and self referencing array problem

I was kinda hoping Nim has some pragma for this :)))

Recursive Fibonacci function

What C compiler and what flags? You can see the c-flags Nim used in the generated source/json. Try compiling the C code with those flags.

Is it possible to write Linux kernel modules in Nim without having to "hack" the Nim compiler?

Like gc:arc can replace kalloc?

"allocate chunks at a time or something" Its the same thing as linked list of arrays, but from different angle :P

realloc and self referencing array problem

When you expand an array/tree where each member has a pointer to other member, but realloc sometimes copy the old data and the pointers are gone. What im doing now is instead of pointers im using indexes, but its not enough flexible if you want to go up/down to parent/child trees. Other solution

Why Svelte is far superior than React (Karax)

That's why in most of the frameworks there's one way data flow. For example in Vue 1 you could do two way updates, in v2 they removed that option.

One might see a difference when using C compiler that generates jump tables, it should be several times faster than if-else

Effect system: filtering tags

"Safety" is a mindset, not a language feature or concept. C# started with the "unsafe" keyword, then Rust came up and they use it as a selling argument. Just look at the kind of people it attracts :/ There is no "Safety"

Please help me understand the performance difference between Nim/Rust in this (contrived) example

Nim's `int` is 8 bytes 64 bit integer, in your Rust code you are using `u32` which is 4 bytes 32 bit unsigned integer. Can you change the Rust example to `i64` and see what happens?

Best practices for porting huge C projects to Nim

Is there any global hook which works with arc? If you importc, lets say a linked list, how do you free it from nim with --gc:arc? There is already existing FreelinkedLists() function in C, how can i call it from Nim?

C FFI using only types?

I made a mistake, ffi.h should be included, not mod.h, now it works

Best practices for porting huge C projects to Nim

What is the best practice for this? You can't do it in one time, I suppose you'll have to use FFI, so my idea was to port Xash3D (Half-Life engine), but its too complicated, the modules are too big and depend of globals, void functions, hash tables, structs with function pointers, etc. So how

Calling nim-server-code from javascript

Did I hurt your feelings? If yes, I'm very sorry for them. Anyway... > But without a "safe by default" runtime, like Deno, there's no much sense > doing it, too dangerous... This is legitimate concern, but the same can be said about installing via Nimble. Or npm.

Call Nim code from C (linking errors)

Doh! Found it. It's gcc that causes the bug, not Nim, it was the **filename case**. Nim generates lower case .c files, but in the project has files with upper case eg. 'TEST.C'. So I reanamed all .c files generated from Nim to uppercase (with .C extension) and it works!

Nimble download/install sequence improvement

Made some mockup [here](https://gist.github.com/JDragan/e53f159c73d4402c8543865e5dc327f9) It downloads the .nimble file and extracts the dependencies. If the package dependencies were in `packages_official.json` it would be a lot faster

Nicer function anmes and other identifiers in the JS output

This could be default way for generating var names, at least those which are not derived. There's no need for names like `var answer_4576375436745 = 42` at all

Avoid adding `m_type` field in JS Objects?

Tnx, it worked! Still, this is a workaround, the good thing about Nim when compiling to JS is that you can use the types, but i still dont see why this extra typeinfo is added, the size of the output could be reduced by half if it wasn't this m_type. Who needs it anyway :)))
