# ticker
A utility of concurrent programming in Haskell, inspired by [Ticker](https://golang.org/pkg/time/#Ticker) in Go.
```haskell
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!
```
More functions are defined in `src/Control/Concurrent/Ticker.hs`.
