I want to read a text file, and store it in a *String*. But readFile will get *IO String*. I search with google and they tell me it is not necessarily to do so. Can you explain to me why is this? Furthermore, How to read a file and store it in a String?
In fact, I want to read a file and split it into *[String]* with *lines*function. Here is what I have tried. link<https://github.com/eccstartup/findDict/blob/master/src/Data/Dict/Utils.hs>I think I could directly operate on *[String]*. But it is not true for me.
