I was checking "sb-ext::run-program", when I found this in
src/interp/nlib.lisp:
#+:sbcl
(defun delete-directory (dirname)
#-:win32 (sb-ext::run-program "/bin/rm" (list "-r" dirname) :search t)
#+:win32 (obey (concat "rmdir /q /s " "\"" dirname "\""))
)
First, the win32 case doesn't run before or after my recent "OBEY" fix.
Second, we have our own in-house |remove_directory| implemented in C.
Are there systems that this C implementation is rejected by 'configure'?
Third, should we really supply our own C implementation, which may be buggy?
It's a pity that filesystem operations are not part of Common Lisp
standard, but there are third party library that aggregates
implementation dependent functions. Shall we use that Lisp library
or a portable C library?
