Hi, I'm doing advent of code 2021 and I have a very very very weird bug where my console is broken and only display a fraction of the lines, when I execute this code :

val data = readFile("day1.txt")
val pairs = data.trimEnd().split("\n").zipWithNext().toMap()
val result = pairs.count { a ->
	return@count a.key == a.value
}
	
pairs.forEach { println("key=${it.key}, value=${it.value}") }
	
println(result)

I don't get the key=something part in my console

I'm using Intellij Idea 2021.3 with Kotlin 1.6.0, Gradle 7.3.1 and here is my repo : https://github.com/Ayfri/advent-of-code-2021

are you using Windows? whatever you used to save the .txt file added DOS-style newlines (\r\n)

[ephemient]

the advent of code site itself only serves \n

[Ayfri]

oh yes, it was Intellij that saved the file using CRLF, thanks !

[ephemient]

it's configurable: https://www.jetbrains.com/help/idea/configuring-line-endings-and-line-separators.html

[ephemient]

but in this case I would recommend saving the file directly from a browser (or scripting the HTTP fetch) instead of copy-pasting

[Ayfri]

Yeah I've done that it's simpler, but I have to use ktor & dotenv libraries (as it requires a session cookie and I'm storing the token into a .env file as I guess it's important to)

[ephemient]

I'm well aware that a cookie is required, that's why my repo has https://github.com/ephemient/aoc2021/blob/main/get-inputs.main.kts + https://github.com/ephemient/aoc2021/blob/main/.github/workflows/get-inputs.yml and session set in GitHub Actions secret. not sure why you'd have to use ktor or dotenv, but sure those could be made to work as well

[Ayfri]

I use ktor for making the request, I know it is possible using JDK but I'm to lazy to haha
