A constant reference/alias or pointer jut like as it is of C++ parameter

I'm honestly noob in Nim, it's so encouraged to detail answer to an explanatory expressions

Found article on concurrency: "Go statement considered harmful"

i dont think this article is just an ad to particular project, now python's asyncio introduced similar concept: [taskGroup](https://github.com/python/cpython/pull/31270), it's a part of structured concurrency; and [some other languages](https://trio.discourse.group/t/structured-concurrency-reso

NimForum 2.2.0 - Fixes a big CVE!

There seems to be quite a lot of `Couldn't render historic post` ([e.g.](https://forum.nim-lang.org/t/7020)). Would it be possible to display these as (suitably escaped) plain text?

Anyone show the iterator on..

By the way, you don't have to specify the type, Nim is able to infer that for you: let u = [ 9, 8, 7, 6, 5, 4, 3 ] for i, v in u: echo i, " . ", v Run

A constant reference/alias or pointer jut like as it is of C++ parameter

In default, parameters are immutable in Nim. Unlike C/C++, Nim doesn't have const type qualifier. Mutability is an attribute of symbol, not type. Please read the Note in end of this section. If you want immutable ref type:

RPC in 10 and REST API in 5 lines of Nim

Hello, What version of nim did you use that the .to_json still works in ? I have tried two different version of nim and they both fail to work at the .to_json can you update the nodem github/codeberg so the source works again with nim?

What do you think about web imports like in Go or Deno, would you like to see them in Nim? import "nimble.io/foo/bar.nim" bar.use() Run On comp time: execCmd ("nimble get gnimble.io/foo/bar.nim") Run

error C2440: '=': cannot convert from 'const char *' to 'NCSTRING'

Initializing `char*` (`NCSTRING`) variable from `const char*` is compile error in C++. It is warning in gcc, but it might be compile error in VCC. You might fix the error by not using `header` pragma. Or cast return value to `cstring` might or mig

Stumped! Extending futures with addition context info

Oops… forget to say thank :-) Much better/simpler! Now I have to double check that actually processes the sites asynchronously… seems to take longer that I would expect… I’ll add start and finish times to the _context_ to make sure they overlap.

error C2440: '=': cannot convert from 'const char *' to 'NCSTRING'

I'm compiling with Windows & VCC/cl and I keep having an issue with a wrapper for a C++ function. This part of the code seems to be the culprit: Here is the wrapper I've written:

Using Nim for system libraries?

@HiPhish \- Yes Go is pretty useless for libraries (particularly on Windows) - any info on Rust's weaknesses here? Looking for arguments that steer users to Nim :-)

Anyone show the iterator on..

Would please anyone show the correct iterator on e.g `var u :array[7, int] = [ 9, 8, 7, 6, 5, 4, 3 ]` to perform for i, v in u echo i, " . ", u Run

Using Nim for system libraries?

When packaging a Nim library as a shared/static library does the client need to call `NimMain()` to statically initialized all the top level `var` s in the stdlib?

Templates and generics

This doesn't work either: type Matrix*[H, W: static int, T] = object data: array[H, array[W,T]] func matrix*[H, W: static int, T](): Matrix[H, W, T] {.inline.} = when H == W: for i in 0..

Can Nim be made more "purely functional""...

> which isn't all that different than as you've done Yeah because you cheated. ;-) I asked for a version that uses the "real" recursion that mine code has and an explicit tail recursion for the "for" loop. Two recursive calls with wildly different characteristics (one needs a stack, the other c

Templates and generics

I wanted to have generic _matrix_ type and constructors like _matrix[2,2,float]()_ and defined-size constructors like _matrix22[float]()_. Anyway I found a solution to my problem: it is not about templates or generics indeed, the static parameters ( _H,W static int_ that define the size of the

Using Nim for system libraries?

This is not all though, after calling a Nim proc from C you need to check the errorflag and make sure an exception wasn't raised, (api missing, bug `<#18215 https://github.com/nim-lang/Nim/issues/18215>_` Also in case there are globals you need to free them afterwards

Templates and generics

I'm not sure what the issue is, but it exists even without using templates as far as I can tell

Stdout problem with nim/lua/love2d (may not be nim related)

I've been using the [nim-lua](https://github.com/nim-lang/lua) bindings with love2d for a while now, and I've compiled some Nim code into dlls, which then get required from lua. But I've always been having this issue that I can't see any errors from Nim in the windows console (I run my love2d g

Can Nim be made more "purely functional""...

FP is not always simpler. From my experience the code in Elixir is frequently harder than same code in Ruby (Elixir is FP language inspired by Ruby).
