In Haskell, to write a file, you can use the writeFile function from the System.IO module. The writeFile function takes two arguments: the file path and the content that you want to write into the file. Here's an example code snippet for writing a file:
import System.IO
main = do
let filePath = "example.txt"
let content = "This is an example text."
writeFile filePath content
In the above code snippet, writeFile function writes the content to the file specified by the filePath variable. Once the code is executed, a file named example.txt will be created in the current working directory with content "This is an example text."
You can also provide a complete path for the file, for instance, /Users/UserName/Documents/example.txt.
Note that if a file already exists with the same name/path, it will be overwritten by the content you write.
