repeatedly

Call a function repeatedly with a delay between each call.

Works on both Erlang and JavaScript runtimes! This means it's good for little scripts, but if you're writing a full OTP program then this isn't the right library to use, and something that exposes OTP compatible APIs would be better.

gleam add repeatedly

import repeatedly

pub fn main() {
  // Print every 500ms
  let repeater = repeatedly.call(500, Nil, fn(_state, i) {
    io.println("Call number " <> int.to_string(i))
  })

  // And at some point later, stop it
  repeatedly.stop(repeater)
}
