Can I do text replacements in a file via a NimScript?

I need to do as part of a build step some string replacements in a text file. In full Nim I'm able to do this via stream reading, text replacements, and stream writing - can I do this in NimScript (i.e. `config.nims`) as well? The `streams` module is not listed for NimScript... Thanks for any p

globalThis is not defined although node version is v14.4.0

interesting. running `node main.js` it works. Maybe by default it is using a wrong node version. I have nvm and I do have multiple node versions installed including v14, v12, v9 and v8.

NimScript tasks with parameters?

How can I use parameters in NimScript tasks? I had a peek at the the `task` template source and it looks like the `...Task` proc does not take any parameters. So do I have to read parameters manually from the command line?

I am confused. Javascript, WASM coroutine support ?

1\. Coroutines are definitely my #1 feature request for Nim, but for now they aren't well supported. The [coro module](https://nim-lang.org/docs/coro.html) is an unstable API that hasn't seen much attention recently. It works well under the arc/orc garbage collector, but has problems with the de

The "var F" thing has nothing to do with the browser, it's the stack trace entries, they work fine in the browser as well as in Node.

I am confused. Javascript, WASM coroutine support ?

Hi. I do like Nim. It is beautiful and easy to develop. I just discovered it yesterday and I believe it is a RUST and GO killer. But I want to see if Nim can fit in my demands right now: 1. Right now, can the coroutines work in Javascript or WASM (source compiled to C and then compiled to was

Thanks! Without `static:` and `block:` it works indeed.

Looking forward to it :)

runnableExamples need random - what can I do?

> Running nim doc on my draft of median.nim Why is it important that runnable examples are inside of `static` and `block`? Are you aware they won't be run at runtime, even without `static`?

I copy-pasted the stuff you posted, fixed wrong types in several places, and the documentation seems ok: proc median*(A: var openArray[int], left, right: Natural, myCmp: proc(x, y: int): int {.nimcall} = cmp[int]): float = result = 1.0 runnableExamples

Subclassing is explained in I know that this topic is missing from the GTK4 book still, but I generally assume that people read the README first.

array sample slower than indexing into rand(size-1)

Nice shirleyquirk! I guess I should just use arrays when performance really matters and I know the size compile time. Would you do it like this? import sequtils import random import times const size = 10_000_000 iterations = 100_000_000 type

If one copies the code after the `block:` statement below into a separate file and moves it to the left, it compiles just fine, but with `runnableExamples` it fails proc median*(A: var openArray[int], left, right : Natural, myCmp : proc(x,y:int):int {.nimcall

array sample slower than indexing into rand(size-1)

Also, I am pretty sure that, besides being slow, `proc rand(r: var Rand; max: Natural)` is also buggy/biased. Git VC history says it used to be correct, but then someone hastily re-did some logic to make it range-inclusive. Briefly, if x <= randMax - (randMax mod Ui(max)): re

Converter string to raw

Raw strings are just the same as a normal string. Only difference is how they are created. With normal strings it will escape things like `\t` to be a tab, but with raw string literals it will be the two characters `\` and `t`. But I assume what you want is to replace all the escape characters b

Generics overload - which one is selected?

The sentence they quoted seem to imply that even if they're both generics, the more specific one should be chosen.

Compile-time string obfuscation

The answer is I need some way to protect my data from been extracting easily for common users. A weak protection goes well. But I am too lazy to encrypt every string to a hard-to-be-judged variable then use the decrypted string by adding, something like, `decrypted(strCryptedName)`, `decrypted(

Generics overload - which one is selected?

`T` and `T` are both generics. You need to use disambiguation like that: proc foo[T: not SomeInteger](A:openArray[T]) = echo "Generic version" echo A proc foo[T:SomeInteger](A:openArray[T]) = echo "SomeInteger version" echo A Run

Compile-time string obfuscation

I think it does not really matter which "encryption" is used since the key is stored somewhere next to the strings.

Compile-time string obfuscation

Why somebody needs this home-made encryption, if you can use `nimcrypto` to encrypt data using AES at compile time?

Manually initializing exception handling

You also should try `-d:noSignalHandler` which removes the exception seq handling code altogether.
