Fill array in C style

Thanks to all for examples. I thought that it is can be done only with generating array/sequence during compile time. @xigoi Sorry, it's my error, you are right. Non zero fill initialization in C really possible only in runtime. Or I must use GCC extension or doing filling sequence with preproc

First program does not compile and is hard to debug

Hello, I spent the last three days learning Nim, and just today coded the application I wanted to do (an image processing filter). As I wrote what I wanted as math, I wanted to code it like math (functionally and using for loops), but Python was too slow, thus I looked for an alternative langua

Can't get basic example of creating reference objects to work. Compilation errors.

Oh no. It's been revealed that all accounts on this forum are just Araq pretending that someone is using his language.

Fill array in C style

By the way, the C code you provided doesn't actually fill the array with 500; it sets the first element to 500 and fills the rest with zeroes.

Why is nimscript interpreted and why the limitations?

It would mean for every single compile time evaluation you'd have to compile a program which will slow down compile time even further. This means for every `static` block or anything that can be done statically you go out to a compiled program. Macros, any constant evaluations through `static` o

Fill array in C style

For clarity this does not require a template, a procedure works fine: proc initArray[T](size: static int, value: T): array[size, T] = for ele in result.mitems: ele = value const arr = initArray(10, 500) const arr2 = initArray(5, "hey") proc mai

Tuple unpacking for an array rvalue?

I am having the same issue!

Fill array in C style

Not sure if there is a better/easier way, but this will only fill the array at compile time: template initArray[T](size: static int, value: T): untyped = block: var res: array[size, T] for i in 0 ..< res.len: res[i] = value res const a

Fill array in C style

Hello. Can Nim fill array with same value (not zero) while defining array? I know about `fill` method in standard library, but it is initialization in runtime (instead of creating static filled memory blocks in pre pre main by compiler). int array[10] = {500}; int main() {

Why is nimscript interpreted and why the limitations?

Genuinely interested about the design decision for nimscript. Why is it interpreted? Is it not possible to compile the nimscript to a local binary and then execute, or JIT compile it? Or is this too complex to implement for little benefit?

Is it possible to create a blockchain with the nim programming language?

It's hard to answer your question unambiguously, cosmos blockchain platform plans to integrate with at least two new programming languages ​​for smart contracts Secure ECMAScript and Kadenamint.

Convert Python codes to Nim codes

Here is with an "unsate" slice version that doesn't use experimental features. It compiles but results are different. I added one string formatting but I think another one is missing #--- # Name:

Issues when creating static library on macOS

Hi all! I'm building a static library named `lightclient` on macOS via this command invocation: nim c --app:staticlib --header:lightclient.h --noMain lightclient.nim Run During the final stage, when the build process invokes `ar` tool, i get this error:

Convert Python codes to Nim codes

Sorry, I'm still lost about how to use the slide.

use memlib call dll proc face nil access

Well you're passing in a null as the third argument, presumably that might be the cause.

I was going bald by the age of 27. If this guy sticks to C++ he's going to be bald before he gets to 21!

Nim without libc?

It depends a lot on what stdlib modules you use as well. The embedded use cases should be good guides. Most things in std/os for example will pull in more C functions.

Nim without libc?

This section of the compiler manual may be useful: For info compiling an hello world program with `nim c --gc:arc --os:any -d:useMalloc` on linux uses the libc functions: U calloc@GLIBC_2.2.5

String vs Array concatenation

The procs in system above with the signature `proc `&`*[T](x, y: sink seq[T]): seq[T]` (notice sink) are supposed to optimize by using inplace `add` (which will not always copy), but they don't seem to do so. Using `add`, if possible, is what you are supposed to do. Copying strings is computati

String vs Array concatenation

I've been benchmarking a bit to see how different things work (in Arturo) and one of these is: concatenation/appending-to an array vs a string. The exact same operation is slower for arrays than for strings. Which is not so surprising. What _is_ surprising is that what I'm calculating is roughly

Nim without libc?

Maybe there is some potential using , that can create executables that work on 6 OS with no change (Linux, Mac, Windows, NetBSD, FreeBSD, OpenBSD). I was asking myself if any Nim guy did play with this... and this post gives me the opportunity.
