;;;; gnus

;; good info http://www.emacswiki.org/emacs/GnusTutorial
;; good info http://www.emacs.uniyar.ac.ru/doc/em24h/emacs183.htm


;; After downloading mailing list archives, once you have an mbox file,
;; there are rather straightforward ways to get it into any mail program,
;; but I will cover gnus, which I use and is a bit tricky.

;; gnus has a native search (limited, too slow for body text searches), and external search engine integration.
;; gnus manual recommends converting to maildir for searching local mail, but importing lots of maildir messages to gnus
;; takes 10+ minutes, so scratch that option. it suggests 2 alternate options
;; mairix. for mbox, it doesn't integrate 100% with gnus, it copies the search results to a mbox
;; and tells gnus to make a group of that mbox and display it. This means the read state won't be persistent, but otherwise
;; works great.

;; local imap server which will use the mbox and provide search.
;; dovecot is modular, theres a dovecot-common which uses recommends to install i guess it's most used modules. Its
;; description is completely not useful. Anyways, I'm not sure if there is any benefit to installing this over just the
;; module we need.
;; pi dovecot-imapd

;; dovecot by default also makes a an inbox folder based on the normal local mail location /var/mail/<username>
;; those locations are adjustable and well documented via the var mail_location in
;; /etc/dovecot/conf.d/10-mail.conf
;; I forward my local mail, didn't see immediately how to turn off the inbox, but it will always be empty, so I left as
;; is. you could make the var be empty, which apparently has the same effect.

;; Originally just linked the default location ~/.mail, but I changed to altering the config since ~/.mail since it seems
;; other things like postfix use that location

;; based on http://roland.entierement.nu/blog/2010/09/08/gnus-dovecot-offlineimap-search-a-howto.html
;; other links that poped up contained outdated, innacurate information
;; http://sachachua.com/blog/2008/05/geek-how-to-use-offlineimap-and-the-dovecot-mail-server-to-read-your-gmail-in-emacs-efficiently/
;; http://www.emacswiki.org/emacs/JamesFerguson
;; http://www.sanityinc.com/articles/read-mailing-lists-in-emacs-over-imap/

;; Within emacs you can move messages between mbox and maildir etc, which is a nice flexibility.



;; doc group for mbox:
;; in gnus, do gnus-group-make-doc-group (G f in groups buffer) and point to the file

;; info about groups created within gnus is stored in ~/.newsrc.eld
;; also stored is a duplication of what email messages are read/unread,
;; what newsgroups are subsribed to and read/unread,
;; probably more stuff, everything that gnus saves.


;; searching the body of the messages, i cut off after a few minutes.
;; i can grep the file in just a couple seconds


;; random side note
;; we can also get mbox from gmane
;; http://notmuchmail.org/howto/#index7h2


;; gnus can't search mboxes except with its builtin search which is extremely slow. mairix can do mbox files from the command
;; line, but not from within gnus, but from mairix.el, which can then open the results in gnus

;; mbox can be converted to maildir easily, but gnus loads lots of maildir messages extremely slow. it parses all the
;; headers and generates a nov file for each.

;; nnfolder-generate-active-file

;; to reset things, when changing mail group. I duno all the proper way, but it works to delete
;; ~/Mail ~/.newsrc.eld ~/.newsrc-dribble


;;;;; mail sources vs select methods background
;; I found this very confusing when first reading through the manual.  "mail sources" is a term that does not simply mean
;; sources of mail, it is much narrower for gnus. sources of mail can be either "mail sources" or select methods. Mail
;; sources will move mail to ~/Mail (not sure what format), and split it into groups according to variables. You can use
;; "mail sources" for maildir / imap, but those can also be read via select methods, which do not move the mail from their
;; location, but use them in their native format. This is what I want to do, and I can simply ignore mail
;; sources. Confusing terminology is that "fetching mail" "scanning mail", lots of things mail doesn't mean all mail, it
;; means specifically from "mail sources". The words "articles" and "news" is used in connection with select methods, aka my actual mail.



;;;;; caching background

;; caching:
;; there is also ~/News/cache, filled with a bunch of articles, like 300 megs. can't figure out why.
;; Grepped for caching in the manual, found 2 main things.
;; cache is for 2 purposes. to cache locally, and to keep articles from expiring, called persistence
;; gnus-use-cache, which puts things if they are
;; gnus-cache-enter-articles
;; things go in cache when they are marked certain ways by default, ticked and dormant
;; and read articles are moved out of the cache
;; still no idea why i have a bunch in the cache, but I set a var so that my mail won't get cached
;; I'm gonna delete the cache, and check on it later see what exactly is going in there
;; And of course, I moved ~/News to my encrypted drive and symlinked it
