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 {{path/to/file.hs}}

• Compile using extra optimization:

ghc -O {{path/to/file.hs}}

• Stop compilation after generating object files (.o):

ghc -c {{path/to/file.hs}}

• Start a REPL (interactive shell):

ghci

• Evaluate a single expression:

ghc -e {{expression}}
