Avandu is an emacs application that connects to a
@uref{http://tt-rss.org, Tiny Tiny RSS} instance and allows you to
read the articles it has gathered locally.

The name avandu was taken from a random web 2.0 business name
generator, as I am very bad at thinking up names.  If you have a
suggestion for a better one, please let me know.

@chapter Installing Avandu

Installing avandu should be easiest when using package.el, the package
manager for emacs 24.  Once this package is uploaded to
@uref{http://marmalade-repo.org/,Marmalade} it should be as simple as
calling

@lisp
(package-install "avandu")
@end lisp

@noindent
but as long as that is not the case, of if you can't use it for some
other reason, another way is to download it, either with
@uref{http://git-scm.com/,git}:

@example
git clone git://ryuslash.org/emacs/avandu.git
@end example

@noindent
or a
@uref{http://code.ryuslash.org/cgit.cgi/emacs/avandu/snapshot/avandu-master.tar.gz,snapshot},
which should then be unpacked.

If you still have package.el available to you, you could use

@lisp
(package-install-file "/location/of/avandu.el")
@end lisp

@noindent
to install it, or you could byte-compile it, place its location
somewhere in your @code{load-path} and either @code{autoload} or
@code{require} it.

@lisp
(add-to-list 'load-path "/path/to/avandu/")

;; And then either:
(autoload 'avandu-list "avandu" "Show a list of feeds." t)
;; or:
(require 'avandu)
@end lisp

@chapter Configuring Avandu

Now that it is installed, it needs to be configured
(@pxref{Installation}), otherwise it won't work at all.

Avandu only has one option at this time.

@defopt avandu-tt-rss-api-url
This option tells avandu where to look for the api to your Tiny Tiny
RSS instance. This needs to be the complete url to the api, for
example @indicateurl{http://tt-rss.org/demo/api/}. Before this option
is set avandu won't be able to do anything.
@end defopt

Other than this, it is possible, but unnecessary to set the following
variables.

@defvar avandu-user
The username that is used to log in to your Tiny Tiny RSS instance.
This will get asked for when avandu tries to connect, and once a
succesful connection has been made it will remember it.
@end defvar

@defvar avandu-password
The password to use to log in to your Tiny Tiny RSS instance.  This
option shouldn't really be set, it is mostly used to remember the
password so that when a session ends, it can easily be restarted.

Setting this variable manually in your emacs init file will make it
easier for others to find, be careful if you do.
@end defvar

@chapter Using Avandu

Once it has been installed (@pxref{Installation}) and configured
(@pxref{Configuration}) it is ready to be used.

Avandu currently offers two things one can do with the stored feeds on
the server.  View an overview of all the articles and see how many
unread articles there are.

@menu
* Article overview:: A list of all unread articles
* Other commands::   Anything else
@end menu

@node Article overview, Other commands, Usage, Usage
@section Viewing unread articles

The avandu overview lets you see a list of all the unread articles in
Tiny Tiny RSS.

@deffn Command avandu-list
Show a list of all the unread articles that your Tiny Tiny RSS
instance has stored, grouped by feed.  Due to certain
@dfn{limitations} of Tiny Tiny RSS, this will only be at most 60
articles at once, or less if the user/admin has changed this setting.

Grouping is done very naively in avandu, as long as articles come from
the same feed, they will be grouped together, if the articles are not
already sorted by feed when avandu downloads them many headings might
be created.
@end deffn

The overview can be used to view these articles. Pressing @kbd{r} on
any article title will mark that article as read, pressing @kbd{o}
will try to open it in your browser (using @code{browse-url}) and mark
it as read.  Using @kbd{c} on any feed heading will @dfn{catch up}
this feed, meaning it will mark all the articles in this feed as read.

Anywhere in the buffer, pressing @kbd{n} or @kbd{p} will move the
cursor to the next or previous article title respectively, and @kbd{N}
and @kbd{P} will do the same, but move to feed headings.

@section All the others

There is also the possibility to see how many unread articles there
are and to manually login and logout of your Tiny Tiny RSS session,
though logging in is done whenever necessary as well.

@deffn Command avandu-new-articles-count
Shows the total number of unread articles in Tiny Tiny RSS in the echo
area.
@end deffn

@deffn Command avandu-login
Log in to the Tiny Tiny RSS instance specified by the user (with
@code{avandu-tt-rss-api-url}, @pxref{Configuration}), ask for the
user's username and password if they're not already known and remember
the session variable that was returned by the api.
@end deffn

@deffn Command avandu-logout
Log out of the Tiny Tiny RSS instance, reset the session id, username
and password used by avandu.
@end deffn
