ghc

The Glasgow Haskell Compiler. Compiles and links Haskell source files. More information: https://www.haskell.org/ghc.

• Find and compile all modules in the current directory:
  ghc Main
• Compile a single file:
  ghc {{file.hs}}
• Compile using extra optimization:
  ghc -O {{file.hs}}
• Stop compilation after generating object files (.o):
  ghc -c {{file.hs}}
• Start a REPL (interactive shell):
  ghci
• Evaluate a single expression:
  ghc -e {{expression}}
