Dir path in Haskell

In Haskell, you can get the current directory path using the getCurrentDirectory function provided by the System.Directory module.

Here's an example code snippet that shows how to use getCurrentDirectory:

import System.Directory (getCurrentDirectory)
main :: IO ()

main = do

    dirPath <- getCurrentDirectory

    putStrLn $ "Current directory path: " ++ dirPath

In this code snippet, the getCurrentDirectory function is called inside the do block to get the current directory path. The resulting path is stored in the dirPath variable, which can then be printed to the console using the putStrLn function.

You can also use the getCurrentDirectory function in combination with other functions from the System.Directory module to manipulate files and directories in the current directory. Here's an example code snippet that shows how to list all files and directories in the current directory:

import System.Directory (getCurrentDirectory, listDirectory)
main :: IO ()

main = do

    dirPath <- getCurrentDirectory

    contents <- listDirectory dirPath

    putStrLn "Current directory contents:"

    mapM_ putStrLn contents

In this code snippet, the listDirectory function is used to get a list of all files and directories in the current directory. The resulting list is stored in the contents variable, which is then printed to the console using the mapM_ putStrLn function.
