Haskell
From Organic Design wiki
Haskell is a functional programming langauge used in Cardano.
Getting Started
Install the Haskell platform with:
sudo apt-get install haskell-platform
Then run the interpreter via:
ghci
Quitting the Haskell interpreter is the same as vim: :q or :quit.
You can write Haskell in .hs files then compile using ghc like so:
ghc -o hello hello.hs
And then you can run via the executable file ./hello.
