[linedit-devel] type error with tab completion

[Martin Bähr]

hi,

using my own completer function i get a type error in sbcl or ccl:

(defun complete (key all)
  (let ((match nil))
    (setf match
          (loop for word in all
                when (equal (mismatch key word :test #'string-equal) 
                            (length key))
                collect word))
    (values match (length match))))


(defun tag-completer (key editor)
  (complete key (mapcar #'symbol-name '(CURRENT RESEARCH TEST WEEK-24 WEEK-25 WEEK-26 WRITEUP))))

(defun prompt-read (prompt &optional default &key complete)
  (linedit:linedit :prompt (concatenate 'string prompt ": ")
                   :string (or default "")
                   :complete (or complete (lambda (a b)()))))

(prompt-read "test" "" :complete #'tag-completer)

test: <tab>
CURRENT  RESEARCH TEST     WEEK-24  WEEK-25  WEEK-26  WRITEUP
test: w<tab>
WEEK-24
