I am writing a program that reads and writes to the same file. I was having some
problems with it writing to the file before it read it. I solved it in the following
two ways:
1.
main = do text <- readFile "test"
let something = somefunc text
writeFile "test2" something
renameFile "test2" "test"
2.
main = do text <- readFile "test"
let something = somefunc text
writeFile "test" $! something
Are both of these correct (guaranteed to give the behavior I want)? Which is better
(and why)?
Thanks!
