Re: [slime-devel] SB-EXT:RUN-PROGRAM and *STANDARD-OUTPUT* interaction in REPL

Executing (TEST T) causes the output go to emacs' *inferior-lisp* buffer, with (TEST *STANDARD-OUTPUT*) it goes to SLIME's REPL buffer, although they should behave the same, AFAICT.

I think T and *STANDARD-OUTPUT* are different in this case. The docstring says:

:OUTPUT Either T, NIL, a pathname, a stream, or :STREAM. If T, the standard output for the current process is inherited. ... If a stream, all the output from the process is written to this stream. ...

The "standard output" is probably the file descriptor 1. At least

(with-output-to-string (*standard-output*) (sb-ext:run-program "/bin/ls" '() :output t))

which just returns "", seems to confirm this.
