Other GNU Emacs Gnus tips

If you have GNU Emacs Gnus check RSS feeds, when you have many feeds defined, Gnus startup can take a considerable amount of time, as it redownloads each RSS feed. This can be quite problematic, especially when you are on a slow connection. Also sometimes you need to just check your email quickly without downloading RSS feeds.

To accomplish this:

1. Setup you email access for Gnus in ~/.emacs and subscribe to your Inbox and the needed folders.
2. Exit Emacs.

3. $ cp ~/.newsrc ~/.newsrc.mail $ cp ~/.newsrc.eld ~/.newsrc.eld.mail

4. Enter Emacs and Gnus and add the need RSS feeds, you wish to be subscribed to.
5. Exit Emacs.

6. $ cp ~/.newsrc ~/.newsrc.mail-rss $ cp ~/.newsrc.eld ~/.newsrc.eld.mail-rss

7. Enter Emacs and Gnus.
8. Unsubscribe from your mail Inbox and all the mail folders, leaving only the RSS feeds as subscriptions.
9. Exit Emacs.

10. $ cp ~/.newsrc ~/.newsrc.rss $ cp ~/.newsrc.eld ~/.newsrc.eld.rss

11. Add the following code to your ~/.emacs:

(defun shiroikuma/gnus-mail-rss ()
  "Use GNUS to read email and RSS streams."
  (interactive)
  (copy-file "~/.newsrc.mail-rss" "~/.newsrc" 't)
  (copy-file "~/.newsrc.eld.mail-rss" "~/.newsrc.eld" 't))
(defun shiroikuma/gnus-mail ()
  "Use GNUS to read email only."
  (interactive)
  (copy-file "~/.newsrc.mail" "~/.newsrc" 't)
  (copy-file "~/.newsrc.eld.mail" "~/.newsrc.eld" 't))
(defun shiroikuma/gnus-rss ()
  "Use GNUS to read RSS streams only."
  (interactive)
  (copy-file "~/.newsrc.rss" "~/.newsrc" 't)
  (copy-file "~/.newsrc.eld.rss" "~/.newsrc.eld" 't))

1. Restart Emacs.

Now when you want to just check your email, run the following one time before starting Gnus:
