One option is to create a file "imports.hs" which contains the text
"import Control.Monad", and then run
ghc -e "forM [[1,2,3]] r

As of 6.10.2, the bug whereby the GHC API lets you use functions from
anywhere just by naming them (Java-style) has not been fixed:
$ ghc -e "Control.Monad.forM [[1,2,3]] reverse"
package f
Can I import a module when using ghc -e?
e.g. ghc -e "import Control.Monad; forM [[1,2,3]] reverse"

interact :: (String -> String) -> IO () is a very handy function for
ghc -e, e.g.
ghc -e 'interact $ lines . map (show . (*2) . read) . unlines'
will multiply the number on every line by 2. (interact takes a
function which maps from entire input to entire output)

It seems to me that you can use getContents, et. al., as you would
from any other Haskell program:
$ echo hello there mauri

xargs ought to do the trick nicely.

Hi,
Is there a way to run 'ghc -e' taking input
from standard input? I would like to use it
in a pipe.
Thanks,
Maurício
