Haskell ghci lambda symbol in prompt

In Haskell ghci is it possible (and how) to get a lambda symbol in the prompt, for instance like this 

λ>

Using Linux Ubuntu terminal.

Solution

  • The command you're looking for is :set prompt. Follow it by whatever you want the prompt to be. You can put this in .ghci, I believe.

    :set prompt "λ> "
:set prompt2 "λ| "
