Re: Physical processes modeling --- libs recommendations?

We have a github repo that is dedicated for tracking these things: [https://github.com/nim-lang/needed-libraries/issues?q=is%3Aissue+is%3Aclosed](https://github.com/nim-lang/needed-libraries/issues?q=is%3Aissue+is%3Aclosed)

Re: Full nimble support for gintro package (high level GTK3 GUI) available

Well, basically we can use Vte. Have just hacked together a minimal test: # https://vincent.bernat.im/en/blog/2017-write-own-terminal import gintro/[gtk, glib, gobject, gio, vte] var cmd: array[2, cstring] = ["/bin/bash".cstring, cast[cstring](0)] proc

Physical processes modeling --- libs recommendations?

Hi folks! I've been more or less active on forum for quite a long time but to tell you the truth, I haven't really used Nim for any "serious" stuff. Now when I started Physical Processes Modeling course as a part of my studies, a friend of my asked me: "Will you use Matlab or Python?". It was

Re: c2nim fails for struct with function pointer containing reference argument, how to convert manually?

If you include the header in the top of the generated file, wouldn't you have two structs, causing a "redefinition of 'struct Foo'" error? \--- begin of file --- #foo.h code struct foo... # original from header #generated code struct foo... # generated from type statement

Re: How to rewrite this C++ code to Nim properly

I think you could find inspiration in the implementation of BitSets and IntSets since they both do low-level bit manipulation and operate on arrays of bytes. BitSets have a fixed memory size while IntSets are dynamically allocated/resized and use refs (GC'ed memory).

Re: "multiple definition" Problem

I solved this by adding the "stb_image.nimble" file in my project folder (I had just the "stb_image" folder). I haven't the motivation to investigate what happened exactly, but anyway, that works.

Re: How do I read BMP file header directly to type?

You should probably also use the `packed` pragma on your type since depending on platform and compiler there could be some padding between the fields of your struct. (ex: between signature and size )

Re: How to cross-compile a Nim executable for Android

Thank you, I did different approach. I followed from this stackoverflow thread about cross compiling

Re: How do I read BMP file header directly to type?

Certainly, but you need to assign to `result`: proc loadBitmapFileHeader*(bitmap: Bitmap, file: FileStream): BitmapFileHeader = static: doAssert(cpuEndian == littleEndian) discard file.readData(result.addr, 14) bitmap.fileHeader = result

Re: How to rewrite this C++ code to Nim properly

The use of `ptr` in Nim is always not safe. For pointer math operation, check this post: [https://forum.nim-lang.org/t/1188#7366](https://forum.nim-lang.org/t/1188#7366) If it's sequence of bytes, you can use `seq[Byte]` or simply use `cstring` together with `cast`

Re: The Nim way to do this

Thanks! Where in the docs are these methods?

Re: The Nim way to do this

let primes = [7, 11, 13, 17, 19, 23, 29, 31] #1 if 7 in primes: echo("Found it!") #2 echo primes.find(13) I don't think count does what you think it does. According to [the docs](https://nim-lang.org/docs/sequtils.html#count,openArray%5BT%5D,T) it "Returns

The Nim way to do this

I've looked through the docs but haven't found the answer to this. I have an array of integers (prime numbers) and I want to: 1) determine if some number is included in the array and 2) return the index value of the number in the array. In Ruby/Crystal I can do the following. What are the
