operating_system

Note: In a while, this package might look abandoned. I can assure you - if Gleam v2 did not drop - it works.

gleam add operating_system@1

import operating_system

pub type OS {
  Windows
  Linux
  MacOs
}

pub fn main() -> Nil {
  let os_name = operating_system.name()
  let os = case os_name {
    "windows_nt" -> Windows
    "linux" -> Linux
    "darwin" -> MacOs
    _ -> Linux
  }
}
