How to use Gnus Group Topics efficiently
Group Topics is used to manage Gnus groups.
For example, you can,
- Place groups (mail folders) from Gmail into "gmail" topic
- Place groups (mails folders) from Outlook.com into "hotmail" topic
- Make "gmail" and "hotmail" belong to the root topic "Gnus"
Enable it is just one line,
(add-hook 'gnus-group-mode-hook 'gnus-topic-mode)
Now comes the question how to delete/add/move the topics?
The official answer is to read its manual.
But there is a simpler solution. All you need to do is insert below code into ~/.emacs or ~/.gnus.el,
(with-eval-after-load 'gnus-topic
(setq gnus-topic-topology '(("Gnus" visible)
(("hotmail" visible nil nil))
(("gmail" visible nil nil))))
(setq gnus-topic-alist '(("hotmail" ; the key of topic
"nnimap+hotmail:Inbox"
"nnimap+hotmail:Drafts"
"nnimap+hotmail:Sent"
"nnimap+hotmail:Junk"
"nnimap+hotmail:Deleted")
("gmail" ; the key of topic
"INBOX"
"[Gmail]/Sent Mail"
"[Gmail]/Trash"
"Drafts")
("Gnus"))))
The management of topics is as easy as editing above code.
My setup always works no matter ~/.newsrc.eld is loaded or not.
BTW, "hotmail" and "gmail" are the keys you used when configuring IMAP accounts,
(setq gnus-select-method
'(nnimap "gmail" ; key
(nnimap-address "imap.gmail.com")
(nnimap-server-port 993)
(nnimap-stream ssl)))
(add-to-list 'gnus-secondary-select-methods
'(nnimap "hotmail" ; key
(nnimap-address "imap-mail.outlook.com")
(nnimap-server-port 993)
(nnimap-stream ssl)))
