Warnings:

The 'description' field should be longer than the 'synopsis' field. It's useful to provide an informative 'description' to allow Haskell programmers who have never heard about your package to understand the purpose of your package. The 'description' field content is typically shown by tooling (e.g. 'cabal info', Haddock, Hackage) below the 'synopsis' which serves as a headline. Please refer to <https://www.haskell.org/cabal/users-guide/developing-packages.html#package-properties> for more details.

ticker

A utility of concurrent programming in Haskell, inspired by Ticker in Go.

import Control.Concurrent.Ticker (newTicker)
import Control.Concurrent.Chan (getChanContents)
import Control.Concurrent.Async (async, cancel)
import Control.Monad (forM_)

main :: IO ()
main = do
  (chan, cancelTicker) <- newTicker (10^3 * 100) -- tick rate: 100ms
  chanStream <- getChanContents chan
  thread <- async $ forM_ chanStream $ \_ -> do
    putStr "Tick!"
  threadDelay (10^3 * 350) -- wait 3 ticks
  putStrLn ""
  cancel thread
  cancelTicker
  
-- Tick!Tick!Tick!
