Question

In Python one can say this:

python script.py

from the command line and receive script.py‘s output inlined. Is it possible to do this with Haskell’s GHCi? Basically I’m wondering if there’s a way to run a Haskell program from the command line without compiling and without the user entering the interpreter.

Answer 1

runghc is what you’re looking for. From its manpage:

runghc is considered a non-interactive interpreter and part of The Glasgow
Haskell Compiler. runghc is a compiler that automatically runs its results at
the end.

Edit: Ubuntu provides a symlink called runhaskell, but it might not be standard.
