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 s-lang macro language.
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.
OPTIONS
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.
-create
Obsolete version of
--create.
--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.
--spool
Read directly from spool.
--version
Print version and some compile time settings.
ENVIRONMENT
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.
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.
FILES
$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).
