lisp-indent-line

lisp-indent-line

[A Soare]

(defun new-lisp-indent-line (&optional whole-exp)
  "Indent current line as Lisp code.
With argument, indent any additional lines of the same expression
rigidly along with this one."
  (interactive "P")
  ...)



lisp-indent-line has one parameter.

However, it is never used in the code as far as I see... I do not understand its logic...

Can somebody explain me its logic , please?

what means that: "With argument, indent any additional lines of the same expression rigidly along with this one." ?

Is it an important feature that worth to be kept in future?

a soare.

  "Indent current line as Lisp code.

rigidly along with this one."
  (interactive "P")
  ...)

And also when I call it using C-u <parameter> TAB the effect is the same as the simple TAB.

So what it shoud have been useful for?

a soare.

Try it on a multi-line sexp.

Look for

       (and whole-exp (not (zerop shift-amt))

Re: lisp-indent-line

Look at this code:

                                 (save-excursion
  (goto-char beg)
  (forward-sexp 1)
  (setq end (point))
                    (goto-char beg)
  (forward-line 1)
                        (setq beg (point))
  (> end beg))


Press C-u 1 TAB. with the cursor on the 1st line.

Do you think that such a feature is useful for something?

I use it all the time.

Agreed, but I think it should be implemented in indent-for-tab-command
rather than in the indent-line-functions.

If this is the C-u TAB feature, it is very important.
And it works when I try it.
