Re-re-starting my adventures in Haskell, for no particularly good reason.

Try the first Project Euler problem: [https://projecteuler.net/problem=1]

GitHub repo is here: [https://github.com/JohnL4/ProjectEuler]

...aaaaand, now I have a blank editor in front of me. Now what?

!!! Output

{{putStr}} and {{putStrLn}} for printing to stdout. __NOTE:__ This only prints ''strings''.  Use {{print}} as a more general-purpose output.

See this page: [2015-09-27-writing-a-simple-haskell-script-from-scratch]

So... the first problem is adding {{ghc}} to your path in emacs (if you use that editor).  

!!! Stack

Actually, a better choice is to install {{stack}}, which managed the entire toolchain for you, kind of like {{npm}} does for Node.

See [https://docs.haskellstack.org/en/stable/install_and_upgrade/], and [http://haskell.github.io/haskell-mode/manual/latest/Compilation.html].  After that, you should be off to the races.
