slrn is an easy to use but powerful NNTP / spool based
newsreader.
It is highly customizable, supports scoring, free key bindings and
can be extended using the embedded S-Lang interpreter.
To use slrn, you either need to set the NNTPSERVER
environment variable to the server you want to read news from or specify a
server on the command line. A newsrc file is needed, too. In case you
do not yet have one, you can create it using ``slrn -f ~/.jnewsrc
--create''.
Inside slrn, online help is available via the '?' key.
The following options can be used when calling slrn from the
command line. They override both environment variables and settings in
private and global configuration files.
- -a
- Read active file when checking for new news.
- -C
- Use colors without checking if the terminal supports it.
- -C-
- Don't use colors, even if the terminal supports it.
- -d
- Get group descriptions (taglines) from the news server. Please note that
this may cause a download of several hundred kilobytes and thus can take a
long time. The output is saved to a local file, so you only need to do
this once. May not be specified in combination with --create.
- -Dname
- Add name to the list of predefined preprocessing tokens, which can be used
in your slrnrc file to have conditionally interpreted lines. See the slrn
reference manual for details.
- -f newsrc-file
- Use file as the newsrc file for this session. This is permanently set via
the server configuration command.
- -h host[:port]
- Connect to the NNTP server on host, overriding the
$NNTPSERVER environment variable. If no port is given, the
default NNTP port (119) will be used. This option is only accepted after
--nntp or when NNTP is the default mode.
- -i config-file
- Read file as the initialization (slrnrc) file. The default is to use
.slrnrc (or slrn.rc on VMS, OS/2 and Windows) in your home directory.
- -k
- Don't read the score file.
- -k0
- Read the score file, but inhibit expensive scoring. A scoring rule
is expensive if it contains header lines that are not included in
the server's overview files. This makes applying them slow.
- -m
- Force mouse support (without checking if it works on the current
terminal).
- -n
- Do not check for new groups (usually resulting in a faster startup).
- -p N
- Use port N to connect to the NNTP server.
- -w
- Wait for a key before switching to full screen mode, allowing the user to
read startup messages.
- --create
- Read the active file (the list of all groups) from the news server to
create an initial newsrc file.
- --debug file
- Write debugging output to file.
- --help
- Show help for command line switches.
- --inews
- Use an external inews program to post articles.
- --kill-log
file
- Keep a log of all articles that were killed by the scorefile in
file.
- --nntp
- Use builtin NNTP support for reading and posting (an external program is
used to post if slrn was compiled with --enable-force-inews).
- --pull
- Spool outgoing articles locally for slrnpull to send.
- --show-config
- Print detailed information about slrn configuration.
- --spool
- Read directly from spool.
- --version
- Print version and some compile time settings.
slrn uses the following list of environment variables.
Note: environment variables can be overridden by configuration files or
command line switches.
- COLORTERM
- If this variable is set, slrn will assume that your terminal supports
ANSI color sequences. It also enables a workaround for a problem
with the mouse reporting when running slrn inside of an rxvt.
- DISPLAY
- If set, slrn assumes that X11 is running.
- EDITOR
- See $SLRN_EDITOR.
- HOME
- See $SLRNHOME.
- HOSTNAME
- If no hostname is given, the value of this environment variable is
used.
- LOGNAME
- See $USER.
- NAME
- Set it to your realname, if slrn can't determine it otherwise.
- NNTPSERVER
- You can use this variable to tell slrn which NNTP server to connect to. It
can be overridden by the command line option -h.
- ORGANIZATION
- The name of your organization.
- PRINTER
- On unix systems, slrn pipes the current article to ``lpr -P
$PRINTER'' to print it.
- PWD
- This variable is only used on unix systems that don't support getcwd(3).
In these cases, it should be set to the current directory at the time slrn
is invoked. This is usually done by the shell and nothing the user has to
worry about.
- REPLYTO
- The value of this variable is used as the default if you do not set
replyto in your slrnrc file.
- SLANG_EDITOR
- See $SLRN_EDITOR.
- SLRNHELP
- You can set this variable to a file slrn should read its online help from.
This is only needed when the default key bindings have been changed and
you want the help function to reflect this. If unset, slrn looks for
help.txt in the configuration directory.
- SLRNHOME
- When interpreting filenames as relative to your home directory, slrn uses
this variable to find out what your home directory is. If $SLRNHOME
is unset, $HOME is used instead.
- SLRN_EDITOR
- The editor to start for editing articles. If this variable is unset, slrn
subsequently looks at $SLANG_EDITOR, $EDITOR and
$VISUAL.
- SLRN_SLANG_DIR
- If set, slrn will search for slang macros here. If not set slrn will
search in the default path, which is defined at compile time (usually
share_dir/slang).
- TMP
- Indicates the directory in which slrn should save temporary files.
- TMPDIR
- See $TMP.
- USER
- Your username, if slrn can't get it from the system by other means.
- VISUAL
- See $SLRN_EDITOR.
- $HOME/.slrnrc
- User-specific configuration file.
- config_dir/slrn.rc
- System-wide configuration file. config_dir is set at compile time
(/usr/local/etc by default).
- $HOME/.jnewsrc
- default newsrc file for slrn.
- $HOME/.jnewsrc.dsc
- Per user newsgroups descriptions.
- share_dir/newsgroups.dsc
- Global newsgroup descriptions. share_dir is set at compile time
(/usr/local/share/slrn by default).
The documentation that comes with slrn, especially
FIRST_STEPS, manual.txt, FAQ and score.txt. If you consider writing S-Lang
macros, also look at README.macros and slrnfuns.txt.
Recent versions of the slrn manual and the FAQ as well as
additional information can also be found on slrn's official home page:

Questions about slrn that are not covered by existing
documentation may be posted to the newsgroup news.software.readers
where they will be answered by knowledgeable users or the author of the
program. In addition, announcements of new versions of slrn are
posted there.
