Note 2: If you run multiple languages in this way (like maybe Lisp?), then you can replace the // This is a comment. Note 1: For convenience, I used the Settings > ShortCutMapper > Plugin Commands to change Execute from F6 to F1. If you don't have a main function in your file, then instead use :cmd return $ unlines. If you don't know about $, you'll learn it soon as it's part of basic Haskell. unlines takes a list of strings and joins them with . ' allows you to execute a string as multiple ghci commands, separated by . Whenever you want to work with a new file, you will have to change yourFileName of course.Įxplanation: :cmd return '. When you open Notepad++ next time, this will still be there. Pressing F6+ENTER will load and run the file again. Type this into the menu: :cmd return $ unlines and press ENTER. Upon pressing the OK button, the Notepad++ console will run the Haskell interpreter.

Suppose you have a file like this in a file called yourFileName.hs: main :: IO () It's a simpler process than it looks and once you do it, you're good to go:

If you're using Haskell with stack, I found a lovely way to run things quickly using NppExec.
