How to define an Emacs command that uses `replace-string` for a specific string (2 answers)

Closed 3 years ago.

I need to remove ascii character 0253 and add a carriage return in it's place. In emacs I do

M-x replace-string ý RET C-q C-j

C-q C-j adds a carriage return. I do this often enough that I creating a custom defun would be much better.

Here is what I have so far

(defun remove-253 ()
   "Removes ASCII Character 0253 and adds a carriage return in it's place"
   (interactive)
   (replace-string "ý" .... not sure what to do next )
)

Your thoughts?

Thanks,

Norm

This worked for me:

(replace-string "ý" "\n")

`repeat-complex-command' (C-x escape escape) should also help you in future problems like this. It shows you the Emacs Lisp form that represents your last complex operation, so you can paste the form directly into a defun and off you go.

In this case, you would see:

(replace-string "ý" "\n" nil (if (and transient-mark-mode mark-active) (region-beginning)) (if (and transient-mark-mode mark-active) (region-end)))

Sounds like a job for keyboard macros. :-)
