I program the advent of code challenges using Kotlin/Native.

Generally the gradle build task generates the binary file, but to read the input you need to call it with different options. Also, you need to set the main file in the build.gradle.kts. I will not go into detail for this.

Kotlin/Native is not different from normal Kotlin when it comes to the math parts of Advent of Code. However the hardest part (so far) was to load the input. I tried two approaches.

I used this sample by jetbrains to generate a library which allows me to use curl: https://github.com/kotlin-hands-on/intro-kotlin-native Then I provided the input on a webserver (Advent of Code requires authentication) and loaded it this way. That workes but I only used it for the first day

On the second day I learned that I can use Okio to read files. I downloaded the input as text file and saved it to resources. Then I added a new task gradle assembleWithResources that copies the resource files and the executable to 'build/ready'. From there one can call the binary and pass the fitting resource file name.

Using multiline Strings one could just copy the input and compile it as Kotlin file. That would be boring, so I didn't do it, but it probably works.
