Re: death to nnrss-snarf-moreover-categories

[jidanni@jidanni.org]

Using nnrss, if one accidentally answers "yes" to "Fetch extra
categories?" how can one clean all 500 of them back out of
~/News/rss/nnrss.el? I tried to edit it by hand but as it is all one
big line, emacs goes crazy with the CPU.

I could delete the file and start again, but there are also other
groups I want in there.

Maybe I need a special function like this, (but for nnrss.el -- which
should be called nnrss.eld to not confuse it with the lisp/*/nnrss.el)
(defun rs-gnus-save-newsrc-with-whitespace-1 ()
  "Save ~/.newsrc.eld with extra whitespace."
  (gnus-message 5 "Adding whitespace to .newsrc.eld")
  (save-excursion
    (goto-char (point-min))
    (while (re-search-forward "(\\\"\\| ((\\| (nn" nil t)
      (replace-match "\n  \\&" t))
    (delete-trailing-whitespace)))
(add-hook 'gnus-save-quick-newsrc-hook 'rs-gnus-save-newsrc-with-whitespace-1)
