Emacs: Escape Quotes Command 💠

This page shows a emacs command to escape/unescape quotes.

For example,

"xyz"

becomes

\"xyz\"

This is very useful when coding lisp to process other languages.

For example, when you have this x = "…", and you want (search-forward "x = \"…\"")

put this in your Emacs Init File:

(defun xah-escape-quotes (Begin End)
  "Add slash before double quote in current line or selection.
Double quote is codepoint 34.

  (interactive
   (if (region-active-p)
       (list (region-beginning) (region-end))
     (list (line-beginning-position) (line-end-position))))
  (save-excursion
      (save-restriction
        (narrow-to-region Begin End)
        (goto-char (point-min))
        (while (search-forward "\"" nil t)
          (replace-match "\\\"" t t)))))

(defun xah-unescape-quotes (Begin End)
  "Replace  「\\\"」 by 「\"」 in current line or selection.
