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
