Get working dir path in Haskell

In Haskell, you can get the working directory path using the getCurrentDirectory function from the System.Directory module.

Here is an example code snippet:

import System.Directory
main :: IO ()

main = do

  currentDir <- getCurrentDirectory

  putStrLn $ "Current working directory: " ++ currentDir

Running this program will output the current working directory in the console.

You can also use the getCurrentDirectory function to get the working directory as a FilePath. Here is an alternative code snippet to the one above:

import System.Directory
main :: IO ()

main = do

  currentDirPath <- getCurrentDirectory

  let filePath = currentDirPath ++ "/file.txt" -- You can create a path by appending to the current dir path

  putStrLn $ "File path: " ++ filePath

In this example, we use the getCurrentDirectory function to get the current directory path as a String and then create a file path by appending a file name to it.
