Hi, does someone have examples of IO programs for reads and writing files ?

Sincere,

Hi Serge,

Here is a barebones implementation of cat (i.e. a use-case of readFile):

Below `main' reads a string from data.txt and writes the obtained
string to standard output:

--------------------------------------------------
module TT where
open import Function using (_∘_)
open import Foreign.Haskell
open import IO.Primitive
open import Data.String using (String; toCostring)

main = (readFiniteFile "data.txt") >>= putStrLn ∘ toCostring ∘ g
where
g : String -> String
g str = str
--------------------------------------------------
