* Description
+ Read RSS feeds in the comfort of DOOM (Emacs)

** Maintainers
This module has no dedicated maintainers.

** Module Flags
+ =+org= to enable ~elfeed-org~ to use ~org-directory/elfeed.org~

** Plugins
+ [[https://github.com/skeeto/elfeed][elfeed]]
+ =+org=
  + [[https://github.com/remyhonig/elfeed-org][elfeed-org]]

** Hacks
+ By default ~elfeed-search-filter~ is set to ~@2-weeks-ago~ and makes the last 2 weeks of entries visible. This needs to be set after elfeed has loaded like so in your ~config.el~
  #+begin_src elisp
(after! elfeed
  (setq elfeed-search-filter "@1-month-ago +unread"))
  #+end_src

* Prerequisites
This module has no prerequisites.

* Features
+ As there isn't currently binding for ~elfeed-update~ you can run it with ~M-x elfeed-update~

* Configuration
** Without +org
When you don't want to use org mode to manage your elfeed feeds you can put your subscriptions to personal ~config.el~ file, ex:
#+BEGIN_SRC elisp
(setq elfeed-feeds
      '("https://this-week-in-rust.org/rss.xml"
        "http://feeds.bbci.co.uk/news/rss.xml"))
#+END_SRC

** With +org
When using ~+org~ flag then configuration is easier. You can use ~org-mode~ to configure feeds to follow.
#+BEGIN_SRC org
,* root :elfeed:
,** Programming :programming:
,*** [[https://this-week-in-rust.org/rss.xml][This Week in Rust]] :rust:
,** News :news:
,*** Top news :tops:
,**** http://feeds.bbci.co.uk/news/rss.xml
#+END_SRC
+ Root of ~elfeed-org~ needs to have ~:elfeed:~ tag. This is where ~elfeed-org~ starts to read.
+ You can have subheaders as in example ~:programming:~, and ~elfeed-org~ applies that tag to all subheader feeds, in example it adds it to ~This Week in Rust~.
+ You can "name" feeds as you please with ~org-mode~ ~org-insert-link~ (~C-c C-l~) and put name as you want into ~description~.
+ If you don't want to use ~org-directory/elfeed.org~ file you can specify it with ~(setq rmh-elfeed-org-files ("path/to/your/elfeed/file.org))~
