SNOWNEWS(1) Snownews 1.5.12 SNOWNEWS(1)NAMEsnownews - console RSS newsreader
SYNOPSISsnownews [-huV] [--help|--update|--version]
DESCRIPTION
Snownews is a console RSS/RDF news reader. It supports all versions of
RSS natively and can be expanded via plugins to support many other
other formats.
The main program screen, that is shown right after you start snownews,
lets you add/remove feeds and update them manually. On the right side
of the screen the number of new items is shown for every newsfeed. To
add a feed press 'a' and enter the URL. This can be either a http:// or
a feed:// URL. If you omit the protocol specifier snownews asumes the
HTTP protocol. To delete a listed feed highlight it with the cursor
keys and press 'D'. A dialog will ask for confirmation.
You can navigate through the main menu with up and down arrow keys or
with 'n' and 'p'. The keys page up/page down, b/space and HOME/END,
</> will scroll a page up or down and to the first or last entry
respectively. Pressing 'r' reloads the highlighted feed from the
server, 'R' updates all feeds in your list and 'T' refreshes the feed
ignoring any cache control data. That means, even if the feed has not
been modified on the server, Snownews will still download the file.
The program will not sort this list alphabetically by default. You can
move items up and down by pressing 'P' and 'N'. To sort the feed list
alphabetically, press 's'.
If you highlight a feed and hit Enter the program will display every
item for this feed. Navigation in all sub menus works as usual. If you
press 'r' the program will reload the current feed. Items may vanish
from the list completely and new newsitems will appear bold or in
colour.
Select an item and hit Enter to read its description. If there is none
attached to it the text "No description available." will be displayed
instead. You can use the arrow keys left and right, repectively 'p' and
'n' to select the previous or next newsitem in the list. Pressing 'o'
will open the link (usually the complete news text) in the browser.
The default browser is lynx, but you can change this by pressing 'B' in
the main menu and entering a new default browser. Or you can edit the
file ~/.snownews/browser. The program replaces %s with the URL when
expanding the string.
You can rename a feed by pressing the key 'c' and entering its new
name. To reset its name to the original title enter '-' in this
textfield.
A context help window is available everytime by pressing 'h'.
Type Ahead Find
For faster navigation in your feedlist you can use Snownews' Type Ahead
Find feature. Press the TAB key and the statusline will change into a
text entry field. While you enter the text you want to search for,
highlight will be automatically placed on items as they match. If you
have selected an item just press enter to open the feed. If there are
multiple items matching you can switch between them by pressing TAB. To
quit Type Ahead delete the search text or press CTRL+G
Categories
Snownews uses categories to manage large subscription lists. You can
define as many categories for a feed as you like. You can then apply a
filter in the main menu that will only show feeds that have a matching
category defined. Feeds with a category will have it printed next to
their name in the main menu.
To add or remove a feed from a category, press 'C' while the feed is
highlighted in the main menu. If you already have defined categories
for other feeds you'll get a list of the existing categories. Just
press its number to add the current feed to this category. To add the
feed to a new category, press 'A' and enter the name of the new cate‐
gory. If you want to remove a feed from a category, just press its num‐
ber in the feed categorization GUI.
You can see all defined categories for a feed in the feed info.
Customizing keybindings
You can customize the keybindings by editing the file ~/.snownews/key‐
bindings. The format is "function description:key". Do not change the
string "function description". The single character behind the colon
represents the key the program will associate with the corresponding
function. If you delete a definition or the program cannot parse the
file for some reason the default settings will be used instead.
Colours
If you prefer to see the world in colours you can enable (and config‐
ure) colour support in Snownews. Edit the file ~/.snownews/colors. To
globally enable colours in the program, set enabled to "1". To set a
colour, use the colour key value that is listed in the comment in that
file. You can disable usage for single items by using the value "-1".
HTML conversion
Snownews will try to convert HTML content into plain text before dis‐
playing the text. Tags will be stripped alltogether and some common
HTML entities will be translated. By default only the five entities
defined in XML (< (<), > (>), & (&), " (") and '
(')) plus a default setting included will be translated. You can influ‐
ence this behaviour with the definition file at ~/.snownews/html_enti‐
ties. See the comments on top of the file for further details.
Importing/exporting subscriptions from other programs:
Snownews can import opml subscription files from other RSS readers into
its own format with the included program "opml2snow". To convert an
opml subscription file type "opml2snow MySubsriptions.opml" with MySub‐
scriptions.opml being the name of the file you want to convert. The
program will print the converted data to stdout. Use "opml2snow
file.opml >converted" to put the converted data into the file "con‐
verted" or "opml2snow file.opml >>~/.snownews/urls" to append it to
snownews' subscription list.
You can also export snownews' internal format to an OPML file with
"opml2snow --export".
See "opml2snow -h" or its manpage for more usage examples.
HTTP client features
Snownews' HTTP client will follow HTTP server redirects. If the URL you
have entered points to a permanent redirect it will update the internal
URL to reflect the new location. Requests will be automatically sent to
the new location from now on.
Snownews supports HTTP authentication and Cookies. To subscribe to a
feed that requires authentication, use an URL http://username:pass‐
word@server/feed.rss. You can use cookies to supply log in information
to a webserver. Put the cookies you want Snownews to use into the file
~/.snownews/cookies. The file has to be in standard Netscape cook‐
ies.txt file format. Mozilla uses this format for example. Snownews
will automatically send the right cookies to the right webserver. You
can also just place a symlink to your browser's cookie file, but it is
not recommended. If a cookie is expired, Snownews will print a warning
on program start and not use the cookie. If a cookie is marked as
secure (only to be used via an SSL secured connection) Snownews will
also discard the cookie.
If you need to use a proxy server to access the internet, set the envi‐
ronment variable "http_proxy". Snownews expects this variable to be in
the format http://your_proxy.org:PORT/
(http://proxy.your_isp.com:8080/).
Automatic update checking
Once a week the program will automatically check for a new version when
it exits. It will request a file named "version" from my webserver and
compare the returned value with the local program version. If they dif‐
fer it notifies the user of a new version. It is done on exit to be
least annoying I hope. This way you can easily ignore it if you don't
want to upgrade for some reason or can't, because you're using a pack‐
age that came with your distribution, etc. To disable this check, put
the value -1 into the file ~/.snownews/updatecheck. Snownews will not
transfer anything to my server. It will just download a file containing
the version number and compare it locally.
Plugins
Snownews has a plugin architecture that allows to load feeds from
external scripts or pipe downloaded contents through a filter. Such a
filter could be an Atom to RSS converter for example. The snownews web‐
site has a section with publically available extensions. See
http://snownews.kcore.de/snowscripts/.
There are two types of filters: execurls and filters.
Execurls are scripts that produce a valid RSS file by themselves. You
can add such extensions by subscribing to a feed "exec:/path/to/exten‐
sion".
Filters convert a downloaded resource on the fly. You usually subscribe
to an URL that is a webpage or a non-RSS feed. If snownews asks you if
you want to use a filter, because it couldn't parse the resource, enter
the location of your script. You can also add filters to exisiting sub‐
scriptions by highlighting the feed and pressing 'e' in the main menu.

BUGS
Reporting bugs
If you think you found a bug in Snownews, please report it. Anything
that makes the program crash, regardless what you're doing is a bug and
needs to be fixed. XML parsing errors are probably not fixable in
Snownews since libxml is responsible for parsing a document's XML.
Though you can report problematic feeds anyway, it may be a bug in
Snownews.
Please read http://kiza.kcore.de/software/snownews/faq#toc4 before you
report a bug.
