Can you show me some Haskell try-catch examples?

Can you show me some Haskell try-catch examples?

Sure! In Haskell, you can use the Control.Exception module for exception handling. Here's a simple example:

import Control.Exception

main :: IO ()
main = do
    result <- try (evaluate (1 `div` 0)) :: IO (Either SomeException Int)
    case result of
        Left ex  -> putStrLn $ "Caught exception: " ++ show ex
        Right val -> print val

What does this code do?

This code attempts to divide 1 by 0, which raises an exception. The try function catches it and prints the error message.

Can you give me another example with file handling?

Absolutely! Here's an example of handling file-related exceptions:

import Control.Exception
import System.IO

main :: IO ()
main = do
    result <- try (readFile "nonexistent.txt") :: IO (Either SomeException String)
    case result of
        Left ex  -> putStrLn $ "Error reading file: " ++ show ex
        Right content -> putStrLn content
