Question

My company has recently added some new code styling rules, and I would was wondering if there is an easy way via emacs to change a couple things w/ a regex replace.

if statements now have to look like the following:

if (expression) {

where I have many that look like so:

if(expression){   

lacking the spaces. Is there an easy way to fix this?

Answer 1

You might be able to regexp replace it if expression is always on one line, but I’d use a throw-away function just to be safe:

(defun my-fix-style ()
  (interactive)
  (save-excursion
    (goto-char (point-min))
    (while (re-search-forward "\\_<if(" nil t)
      (backward-char)
      (insert " ")
      (forward-sexp)
      (unless (looking-at "[ \t\n]")
        (insert " ")))))
