Native GUI development for MacOS

It doesn't help that Apple keeps changing everything. We like Java, use that, no wait, use Objective C. You can use Carbon, wait no, use Cocoa, wait no, use Swift UI. Use OpenGL, no wait, ...

Cross-Compiling for Windows 32-bit with ChooseNim Install

It's rather easy when you don't use Choosenim. Download our 32bit zip, unpack, run "finish.exe". For a cross compile, download our 64bit zip, unpack, install the MingW of your choice, add it to your %PATH% and use `--cpu:i386 --os:windows` for the Nim compiler invocation.

What Nim projects are you working on?

I am currently working on a simple invoice creation tool for sole traders. Currently thinking what UI choices to make when the user has made a wrong input in Gtk. (Not sure how to force-contain the image into the frame) Since I am using a popover widget to collect data, really not sure where to

Native GUI development for MacOS

> Actually its just amazing, why so obvious task like UI for mac Because it’s difficult, and a large task considering the API surface area. Also, IMHO a large proportion of the OSS/hacker community either use Linux ... or if on a Mac don’t really care about apps other than Terminal and a web br

Own numeric type

Sounds like you want an enum, with those integers assigned to the values.

Own numeric type

Do you have some unusual arithmetic going on here? in that case you might want to define a class, and/or use an enumeration.

Cross-Compiling for Windows 32-bit with ChooseNim Install

I haven't cross-compiled from a Windows OS, but you can take a look at the cross compiling setup here It builds 32 bit and 64 bit Windows binaries from Mingw64 (but from a Linux host)

Own numeric type

The point of having a numerical type is to have the ability to perform mathematical operations, but in case of a restricted set of numbers most of the time you'll be getting answers outside of the set, so you still need to perform checks afterwards. So either you just use the regular numbers and

Docker image for cross compiling

This is now current with Nim 1.4.2. There are tags for 1.0.10 and 1.2.8 as well.

arraymancer ``

Yes, nimhdf5 works great. Thanks @Vindaar. I'll try to open an issue on the arraymancer repository.

how use custom event inherited from DOM Event in javascript?

Have you tried just casting the event you get to the vent you want? `cast[Event]` ? I usually do that with JS events see here:

Own numeric type

That's not a language feature, possibly due to the low number of actual use cases for it.

Error Using _kbhit with .importc

Hm. Yeah I think a full implementation of this would require implementing the basic keyboard code via getConsoleInput and peekConsoleInput as needed for other items.

Cross-Compiling for Windows 32-bit with ChooseNim Install

Hi, I have installed Nim v1.4.2 installed via choosenim on an x64 Windows box, and allowed it to install the default MinGW64 toolchain. It works fine until I try to cross-compile an executable to Windows 32-bit. I'm aware MinGW is rather fiddly when it comes to cross-compiling to x86 targets, h

What am I doing wrong with streams

Whenever I sit down to write a program I know that I will do something wrong. Generally that doesn't stop me from coding something that works, but in [this case](https://github.com/Lecale/piggy/blob/main/piggy.nim) it has. I open an input and an output stream from osproc's StartProcess. In the i

Creating Custom DLLMain using MSVC

Hi, I'm currently attempting to create a DLL with a custom DLLMain function in Nim. Based on [this forum post](https://forum.nim-lang.org/t/1973\]) , I created the DLL as follows: import winim/lean proc NimMain() {.cdecl, importc.} proc DllMain(hinstDLL: HINSTANC

C++ bindings - doubt with an argument's default value

Thanks. Understood. It looks I have to do: proc constructMaterial*(mat: Material, copyop: CopyOp = constructCopyOp(CopyFlags(SHALLOW_COPY))): Material {.constructor,importcpp: "osg::Material::Material(@)".}## Copy constructor using CopyOp to manage deep vs shallow copy.

Native GUI development for MacOS

I've tried nimx one of the first, it works fine with OSX but is far from native :( Actually threre is one wrapper: , it emits Objective-C commands directly to Cocoa API, as I understand. It works perfect but only for two things: file open and sa

Own numeric type

Hi All, Could someone pls. help me with this: I would like to create own numeric type which consists for example only from these numbers "0,1,3,6,8,9". I was successful with range: type my_num_type = range[0..9] However I do not want to have 2,4,5,7 there. Thanks Peter

Native GUI development for MacOS

You might try [nimx](https://github.com/yglukhov/nimx). I've never assessed how "native look & feel" it is, but it claims to support MacOS and is well maintained.

Native GUI development for MacOS

Thanks for reply, I've tried wxnim but it does not work out of repository: it returns a dozen of various errors upon compilation of its examples. Same time wxWidgets itself was compiled fine at one click. I guess it is due to non maintainable code which is not up to date to current NIM and wxWid

C++ bindings - doubt with an argument's default value

It seems like `Options` is implicitly convertible to `CopyOp` on C++ side, but this is not the case in nim. In general, C++ default arguments should be wrapped using `arg: Type = initType(defaultValue)` where `toType` is wrapper for implicit conversion constructor on the C++ side. In C++ defaul

C++ bindings - doubt with an argument's default value

I have doubts with the following header: [Material](https://github.com/openscenegraph/OpenSceneGraph/blob/40bddd8d9532620dc704adce0d2fb0c854d62d0f/include/osg/Material#L38) from OpenSceneGraph: namespace osg { /** Material - encapsulates OpenGL glMaterial state.*/ class OSG

Seems like a bug? SIGSEGV: Illegal storage access.

Maybe we should say then - don't use function as "or" types, as it would make it hard to use it later. And using simple code like `fn((arg) => arg.hi())` won't be possible.

Cancelation points in async

[chonos](https://github.com/status-im/nim-chronos/) supports cancellation, though in a slightly different way - you don't complete the future with `fail` \- you `cancel` it - using `fail` like that might be hard to reason about because you now have multiple "owners" fulfilling the promise.

arraymancer ``

First of all I'm happy to hear that `nimhdf5` works well to read NetCDF files! Slicing on tensors in arraymancer based on boolean conditionals was only added relatively recently. I assume that it's an oversight that there is no variant of `index_select` and similar (which `[x !=. 0.0]` calls), w
