slrn (``S-Lang read news'') is a Usenet newsreader that runs in text mode on various Unix and Unix-like operating systems (including Linux), Windows, OS/2, BeOS, MacOS X and VMS.
It supports scoring rules to highlight, sort or kill articles to make reading
news more efficient. Furthermore it is highly customizable, allows free
key-bindings and can be extended using the S-Lang macro language. Offline
reading is possible using either
slrnpull (shipped with
slrn) or a
local newsserver like Leafnode or INN.
If you run Linux, your distribution probably contains a
slrn package that
might not offer the latest version, but is more or less ``ready to go''.
If you wish to obtain a more current version of
slrn for Linux or another
supported OS, details can be found at
Additional resources are available at <http://slrn.sourceforge.net/>.
Note: Upgrading is especially recommended if you are currently using a 0.9.8.1pl1 or pl2 version, in which significant bugs exist.
The source distribution contains a lot of documentation; on Unix-like systems,
it is likely to be installed somewhere in
/usr/doc. It contains manpages (type
man slrn at the command
prompt), the slrn Reference Manual (
manual.txt) and several other
useful resources like a sample slrnrc (configuration) file.
If you are new to
slrn, please make sure to read the file
FIRST_STEPS. It should get you started.
If you cannot find this documentation on your system, you can find it online via <http://slrn.sourceforge.net/documentation.html>.
If you have general questions about
slrn that are not covered by its
documentation, please make use of the appropriate newsgroups or mailing list
rather than writing to the maintainer directly:

slrn-user is a mailing list for discussion of the use, development and

To keep track of
slrn's development, simply subscribe to slrn-announce.
It is a low-traffic moderated list that informs you about new releases,
important bugfixes or major changes to the website. The subscription address
announcements are also mailed to slrn-user, so there is no need to read both
slrnappears quite stable. Why don't you call it version 1.0?
The main reason for the sub-1.0 version number is the poor handling of
different character sets. Users of a modern newsreader expect it to support
Unicode as well as legacy character sets. So, you'll see
slrn 1.0 as
slrn is ported to the new slang-2 library and running
Since version 0.9.8.1pl1,
slrn compiles against slang-2.
Since version 0.9.8.1pl2,
iconv for internal charset
handling and supports UTF-8, with some bugs left.
Both versions were never officially released, although some Linux distributions shipped them.
In version 0.9.9 a lot of bugs in the UTF-8 handling have been fixed.
A current drawback of slang-2 is that its regexp engine lacks UTF-8 support.
When you run
slrn in UTF-8 mode, you should have your score file in UTF-8
as well. You may still encounter surprising results; in particular, regexp
matching has no error handling for invalid UTF-8.
Since there were fundamental changes in the internal character set handling,
the configuration of this has also changed. The configuration variables
charset, editor_uses_mime_charset, fold_headers,
mime_charset and use_mime, and the configuration command
compatible_charsets are no longer valid. To set character sets for
display, editor and posting, use the new
charset command instead.
