This section describes functions for reading Lisp objects with the minibuffer.
This function reads a Lisp object using the minibuffer, and returns it without evaluating it. The arguments prompt and initial are used as in
This is a simplified interface to the
read-from-minibufferfunction:(read-minibuffer prompt initial) == (let (minibuffer-allow-text-properties) (read-from-minibuffer prompt initial nil t))
Here is an example in which we supply the string
"(testing)"as initial input:(read-minibuffer "Enter an expression: " (format "%s" '(testing))) ;; Here is how the minibuffer is displayed: ---------- Buffer: Minibuffer ---------- Enter an expression: (testing)-!- ---------- Buffer: Minibuffer ----------
The user can type <RET> immediately to use the initial input as a default, or can edit the input.
This function reads a Lisp expression using the minibuffer, evaluates it, then returns the result. The arguments prompt and initial are used as in
This function simply evaluates the result of a call to
read-minibuffer:(eval-minibuffer prompt initial) == (eval (read-minibuffer prompt initial))
This function reads a Lisp expression in the minibuffer, evaluates it, then returns the result. The difference between this command and
eval-minibufferis that here the initial form is not optional and it is treated as a Lisp object to be converted to printed representation rather than as a string of text. It is printed with
prin1, so if it is a string, double-quote characters (‘"’) appear in the initial text. See Output Functions.
In the following example, we offer the user an expression with initial text that is already a valid form:(edit-and-eval-command "Please edit: " '(forward-word 1)) ;; After evaluation of the preceding expression, ;; the following appears in the minibuffer: ---------- Buffer: Minibuffer ---------- Please edit: (forward-word 1)-!- ---------- Buffer: Minibuffer ----------
Typing <RET> right away would exit the minibuffer and evaluate the expression, thus moving point forward one word.
