Thanks a lot! I thought that option resided in ghci or runghc apps. On Jan 18, 2008 2:00 PM, Clifford Beshers wrote:

Hi,

I don't know if it's been asked before. I just wonder if GHC supports some sort of one-liner program that can be specify right as the argument to either ghci or runghc program. In perl, they have something like

perl *-e* 'print "Hello"'

Do we have similar thing with GHC?

ghc -e 'putStrLn "Yes, we do."'

Thanks all. This really helps me a lot! On Jan 18, 2008 6:24 PM, Jonathan Cast wrote:

Although, unlike perl, you don't have to say print explicitly if you don't need it:

ghc -e '"This works great!"'
