Remove leading and trailing whitespace in Haskell

In Haskell, there are several ways to remove leading and trailing whitespaces from a string. One common method is to use the Data.Text module, which provides the strip function.

Here is an example of how to use strip:

import Data.Text (strip)
-- strip leading and trailing whitespaces

strip "  Hello, world!  "  -- returns "Hello, world!"

In this example, the strip function removes all leading and trailing whitespaces from the input string " Hello, world! " and returns the result string "Hello, world!".

Alternatively, you can also use the trim function from the Data.List.Utils module:

import Data.List.Utils (trim)
-- trim leading and trailing whitespaces

trim "  Hello, world!  "  -- returns "Hello, world!"

The trim function works similarly to strip and removes all leading and trailing whitespaces from the input string.

Regardless of which function you use, these methods will help you remove leading and trailing whitespaces from a string in Haskell.
