Too much memory used for N-queens problem

yes it's not the most memory efficient solution. i believe i did one of these using bitsets but i can't find it. at n=15 there are almost 2.3 million solutions so the data structure you use to hold a solution better be small. if you're representing a solution as a seq[int] with length 15 and may

Error: unknown substition variable: attype

i got that error too when trying to install nimterop, due to my crappy internet and an interrupted download. the problem was a git clone left an empty folder somewhere. I think `nimble uninstall nimterop` and `nimble install nimterop` should do it, or `rm -rf ~/.nimble/pkgs/nimterop*` manually

Trying to use openssl RSA funcitonality in nim

Too much memory used for N-queens problem

I'm sorry for making that much posts on my first day after signing up, but I have been testing several other Nim implementations and I thought this would also be interesting. I made a similar post today on I encountered the following program:

Why memory leaks with ARC/ORC on platform game?

Hello, I have been looking for some game developments on Nim and I found the following: A platforms game made in Nim. Well, the problem with this is that if I compile with arc or orc my RAM memory gets filled slowly but steady. If I use the default

Thank you. I saw a few mentions about some of unittest which should not be used with testament.

Thank you for your suggestions, indeed it's better like this.

Initializing subclassed objects, like C++ Constructors

not completely satisfying, but maybe gets somewhere towards what you're after: type Point = object x, y: float proc initPoint(): Point = Point(x: -1) type Circle = object of RootObj p: Point r: float # and now the chaine

Testament documentation - test-case, test-step, setup, tearDown

I'm trying to port one of my python packages to nim. The package uses [pytest](https://docs.pytest.org/en/stable/) I'm really confused about testing in nim. The documentation for testament (at lest the one I've managed to find) is mostly about how to invoke it. Most searches just finds some iss

Initializing subclassed objects, like C++ Constructors

In C++ we often see constructor code like CircularArc2D::CircularArc2D(const CircularArc2D& arc) : CircularDisk2D( arc ) { m_StartPoint = arc.m_StartPoint; m_EndPoint = arc.m_EndPoint; } Run Here CircularArc2D is a subclass of CircularDisk2

respecting the conventions when declaring a function pointer in a tuple

this is correct. when implementing a function table you should prefer {.nimcall.} to avoid the extra overhead of {.closure.} while i don't know the rest of your logic, so maybe there's a reason you've structured things that way, but perhaps you might like to consider as an alternative:

How to best access a potentially const variable in a func that is to big for default stack?

oh i know, nimsuggest crashes and it does take ages to populate that 64MB array, and yes while testing there were several times i got a SIGKILL. i'm trusting that it's a crucial optimization for your use case. bear in mind `let defaultB:B = ` will calculate the result at runtime, the tradeoff b

How to best access a potentially const variable in a func that is to big for default stack?

The `const` thing works, I tried it again, the issue is that it takes ages to compile. Apparently it would also work when using `let defaultB: B = block:`, the first issue I had is that I didn't use `block` but an extra function which resulted in program termination (I am not 100% sure that it w

Chrome Extensions with Nim, who would have thought?

Yeah, if only I had the time to make a video :( I had originally wanted to start doing YT tuts for Nim and even bought nimprogramming.com for companion posts to the vids... but I'm going to have to sit on it all for now, I got way too busy on my business. I'll put a repo up though of the sample

Demystifying nimDecRefIsLast

I guess every approach has its own trade-offs. One of the big advantages of a Rebol-ish language is its extreme flexibility. So, on one hand, you can do many (weird) things super-easily, but one the other hand, it has to be handled with... caution. The debate is pretty much like compiled vs int

Demystifying nimDecRefIsLast

Don't use nimprof, it's unreliable for CPU bound code and hardly maintained. Use a real profiling tool. And then rewrite your VM, it's never gonna be fast anyway. ;-)

Sorry, it's my fault, I changed it to "announcement". I changed it back to "default".

Demystifying nimDecRefIsLast

The VM right now is pretty much proof of concept and hardly optimized. I guess I could bring it to more a competitive level with mainstream scripting languages, in the future. The main goal is to go totally self-hosted with an LLVM backend - but that's not my main concern right now. What would

Chrome Extensions with Nim, who would have thought?

That's not an announcement. If "it works", as you say, then where's the code? Looks nice and official though, using the Nim logo as your avatar. And it's good promo for a yt video.

Demystifying nimDecRefIsLast

After I compiled my project for profiling and opened the `profile_results.txt`, I can see that `nimDecRefIsLast` consumes a significant part of the calls and time. What would you look for in the code if you had results like this? (I admit I haven't yet spent any time in optimizations; I rather

NimScript tasks with parameters?

I made a procedure that’d parse the parameter strings and return a configuration object. If a sub-task needed the config it just (re)calls the parsing procedure. Inefficient but straightforward and no init checks required.
