提示中的Haskell ghci lambda符号

Question

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.

Answer 1

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| "

Answer 2

您可以使用以下命令来使用lambda字符：

:set prompt "\x03BB: "
