Dear Huang Ying,
I found in README of inferior-shell, it is said that the default output mode is as follow:
NIL (default) for inheriting the parent process's stdout,
But in recent uiop implementation, the ":output nil" means to redirect to /dev/null, while ":output :interactive" means to inherate the parent process's stdout (at least for sbcl).
So I think we should change the default value of output parameter for run or change the README.
What do you think about that?
Thanks for the bug report. I've slightly edited the README for now. And some people claim that the concept of "bitrot" is impossible! —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org [A] Computer [programming] language is inherently a pun — [it] needs to be interpreted by both men & machines. — hbaker
