Yes, 21.3.5 is a CVS version. The SLIME maintainers will need to decide
whether they want to add the read-directory-name function to slime or
re-write it in order to support earlier emacs versions. FWIW, the function
is in files.el - here's the source:
(defun read-directory-name (prompt &optional dir default-dirname mustmatch
initial)
"Read directory name, prompting with PROMPT and completing in directory
DIR.
Value is not expanded---you must call `expand-file-name' yourself.
Default name to DEFAULT-DIRNAME if user enters a null string.
(If DEFAULT-DIRNAME is omitted, the current buffer's directory is used,
except that if INITIAL is specified, that combined with DIR is used.)
Fourth arg MUSTMATCH non-nil means require existing directory's name.
Non-nil and non-t means also require confirmation after completion.
Fifth arg INITIAL specifies text to start with.
DIR defaults to current buffer's directory default."
(unless dir
(setq dir default-directory))
(unless default-dirname
(setq default-dirname
(if initial (concat dir initial) default-directory)))
(read-file-name prompt dir default-dirname mustmatch initial
'file-directory-p))
Cheers,
Bill
