A simple project has the following files included in it:
➜ helloworld ls LICENSE Setup.hs helloworld.cabal src stack.yaml
In the folder
src there is a file named
Main.hs. This is the "starting point" of the
helloworld project. By default
Main.hs contains a simple "Hello, World!" program.
module Main where main :: IO () main = do putStrLn "hello world"
Make sure you are in the directory
helloworld and run:
stack build # Compile the program stack exec helloworld # Run the program # prints "hello world"
