mcabber - Online in the Cloud

PROGRAM:

NAME

mcabber - a simple Jabber (XMPP) console client

SYNOPSIS

mcabber [ -h | -V | -f configfile ]

DESCRIPTION

mcabber(1) is a small Jabber (XMPP) console client. For now it needs a configuration file
to start, so please copy the sample mcabberrc file and adapt your connection settings.

You also need to have an existing Jabber account to use this software, as it cannot
(un)register accounts yet.

Here are some of the features of mcabber:

· SASL/SSL/TLS support.

· MUC support (Multi-User Chat).

· PGP, OTR support

· Chat States support (typing notifications)

· History logging: If enabled (see the CONFIGURATION FILE section), mcabber can save
discussions to text history log files.

· Commands completion: If possible, mcabber will try to complete your command line if
you hit the Tab key.

· Input line history: Any message or command entered is in the input line history and
can be reused easily.

· External actions: Some events (like receiving a message) can trigger an external
action such as a shell script if you enable it in your configuration file. A sample
events script ("eventcmd") is provided with mcabber source code, in the contrib
directory.

· Modules: mcabber can load modules (a.k.a. plugins) at runtime that extend its
features.

OPTIONS

-h
Quick help usage message

-V
Displays mcabber version and compile-time definitions.

-f configfile
Use configuration file configfile

WINDOWS/PANES

The mcabber(1) screen is divided into 4 regions. The roster, alias buddylist, is on the
left. The chat window, or chat buffer, is on the right. The input line lies at the bottom
of the screen, under a small log window.

Two status lines surround the log window. The bottom status line is the "main status line"
and reflects mcabber general status. The other line is the "chat status line" and shows
the status of the currently selected buddy.

To display buddies chat buffers, you will have to enter chat mode. You can enter chat mode
by pressing enter, and leave chat mode with the ESC key. Simply sending a message will
also enable chat mode.

There are several advantages to the two-mode implementation: first, it allows accurate
"unread" message functionality, as described in the next section; without this, merely
scrolling to a specific buddy will "read" the new messages of all buddies in-between.
Second, it allows quickly hiding the conversation with a single keystroke. Third, it
allows jumping between the few buddies with whom you are conversing with the /roster
alternate command described in another section, without having to manually scroll back and
forth.

KEYS

Text typing occurs in the input line; basic operations are supported (left arrow, right
arrow, home/end keys, insert, delete, backspace...).

PageUp and PageDown keys are used to move in the roster.

Up and Down arrow keys can be used to move in the input line history; they jump to the
previous/next line from the history beginning with the same string (from first column to
the cursor column).

To send a message, move to the chosen buddy in the buddylist, type your message and hit
enter. If the line begins with a slash, this will be interpreted as a command (see the
COMMAND section below). Hit escape to leave the chat mode.

Here is a quick description of the default key bindings:

Esc
Disable chat mode

Ctrl-a
Go to the beginning of the input line

Ctrl-e
Go to the end of the input line

Ctrl-l
Force a refresh

Up/Down
Move in the input line history

PgUp/PgDown
Move inside the roster (buddylist)

Tab
Complete current word, in the input line

Ctrl-g
Cancel completion

Ctrl-c
Abort multi-line messages and completions

Ctrl-d
Send/terminate a multi-line message

Ctrl-p/Ctrl-n
Scroll up/down half a screen in the buffer window (chat mode)

Ctrl-Left
Move the cursor back to the start of the current or previous word

Ctrl-Right
Move the cursor forward to the end of the current or next word

Ctrl-u
Delete from beginning of the line to the cursor

Ctrl-k
Delete from the cursor to the end of line

Ctrl-w
Backward kill word

Ctrl-t
Transpose chars

Ctrl-o
Accept line and put the next history line in the input line
(accept-line-and-down-history)

Additional key bindings may be specified using the /bind command described in the COMMANDS
section.

MCABBER’S ROSTER

The first listed item on the roster is [status], which keeps a log of everything that
appears in the short log window below the main chat area. While the log window was
designed for showing the latest few elements, the dedicated [status] buffer allows more
comfortable viewing of the log, as well as scrolling it in a standard manner.

Group names are displayed above the items that are within them, and are indicated by ---
to the left of the name.

For every real Jabber contact, the roster displays four pieces of information: the buddy’s
name or alias, its online status, its authorization status, and whether there are unread
messages from the buddy waiting for you.

The online status is one of the following:

o
online

f
free for chat

a
away

n
not available (labeled extended away in some clients)

d
do not disturb

_
offline (or invisible to you)

?
unknown, usually meaning you are not authorized to see this buddy’s status

x
a conference room in which you are not participating

C
a conference room in which you are participating

The authorization status indicates whether a buddy is authorized to receive your online
status updates, and is displayed by the brackets surrounding the buddy’s online status.
Square brackets, like [o], indicate that this buddy is authorized to receive your status.
Curly braces, like {o}, indicate that they are not authorized to receive your status.

When there are unread messages from a buddy which you have not looked at, a hash mark (#)
appears in the leftmost section of the roster for that buddy. The hash mark disappears
once you view that buddy’s message buffer. When the user attention is requested (or when
you receive a message containing your nickname in a MUC room), the hash mark is replaced
with the attention sign, an exclamation mark (!).

Examples:

--- Buds
This is a group named Buds

#[o] John
John is online, can see your status, and sent you a message that you did not read yet

{?} Sally
Neither you nor Sally have authorized each other to see your online status

{a} Jane
Jane is away, but she cannot see your online status

#[C] [email protected]
You are participating in [email protected] conference room, and there are unread messages

COMMANDS

/move [groupname]
Move the current buddy to the requested group. If no group is specified, then the
buddy is moved to the default group. If the group "groupname" doesn’t exist, it is
created.

Tip: if the chatmode is enabled, you can use "/roster alternate" to jump to the moved
buddy.

/msay begin|verbatim|send|send_to|toggle|toggle_verbatim|abort
Send a multi-line message. To write a single message with several lines, the
multi-line mode should be used.

In multi-line mode, each line (except command lines) typed in the input line will be
added to the multi-line message. Once the message is finished, it can be sent to the
current selected buddy with the "/msay send" command.

The begin subcommand enables multi-line mode. Note that it allows a message subject to
be specified.

The verbatim multi-line mode disables commands, so that it is possible to enter lines
starting with a slash. Only the "/msay" command (with send or abort parameters) can be
used to exit verbatim mode.

The toggle subcommand can be bound to a key to use the multi-line mode quickly (for
example, "bind M13 = msay toggle" to switch using the Meta-Enter combination).

send_to [-n|-h] jid
Send the current multi-line message to "jid"

toggle|toggle_verbatim

abort
Leave multi-line mode without sending the message

The -n or -h flags turn the message to "normal" or "headline" accordingly, as opposed to default "chat" message.

/otr key, /otr start|stop|info [jid], /otr fingerprint [jid [fpr]], /otr smpq|smpr [jid]
secret, /otr smpa [jid]
You can use the shortcut-jid "." for the currently selected contact.

key
Print the fingerprint of your private key to the Status Buffer

start [jid]
Open an OTR channel to the specified jid (or the currently selected contact)

stop [jid]
Close the OTR channel to the specified jid (or the currently selected contact)

info [jid]
Show current OTR status for the specified jid (or the currently selected contact)

fingerprint [jid [fpr]]
Show the active fingerprint of an OTR channel. If the fingerprint is provided
instead of "fpr", the fingerprint will become trusted. If you replace "fpr" by
some bogus string the fingerprint will loose the trusted status.

smpq [jid] secret
Initiate the Socialist Millionaires Protocol with the secret and the buddy

smpr [jid] secret
Respond to the Initiation of the jid with the secret

smpa [jid]
Abort the running Socialist Millionaires Protocol

/otrpolicy, /otrpolicy (default|jid) (plain|manual|opportunistic|always)
You can use the shortcut-jid "." for the currently selected contact.

(without arguments)
Prints all OTR policies to the status buffer

(default|jid) (plain|manual|opportunistic|always)
Sets either the default policy or the policy for the given jid The plain policy
should never be used, because you won’t be able to receive or send any OTR
encrypted messages. If you set the policy to manual, you or your chat partner have
to start the OTR encryption by hand (e.g. with /otr start). The policy
"opportunistic" does that itself by sending a special whitespace-sequence at the
end of unencrypted messages. So the other OTR-enabled chat client knows, that you
want to use OTR. Note that the first message will always be unencryted, if you use
this policy. With the policy "always" no message will be sent in plain text. If
you try to sent the first message unencrypted, mcabber will try to establish an
OTR channel. Please resend your message, when you get the information that the
channel was established. If someone sends you plaintext messages while the policy
is set to "always", you’ll be able to read the message but it won’t be saved to
the history.

/pgp disable|enable|force|info [jid], /pgp setkey [jid [key]]
This command manipulates PGP settings for the specified jid (by default the currently
selected contact).

Please note that PGP encryption won’t be used if no remote PGP support is detected,
even if PGP is enabled with this command. You can force PGP encryption with the
"force" subcommand.

disable [jid]
Disable PGP encryption for jid (or the currently selected contact)

enable [jid]
Enable PGP encryption for jid (or the currently selected contact)

force [jid]
Enforce PGP encryption, even for offline messages, and always assume the recipient
has PGP support. If a message can’t be encrypted (missing key or key id), the
messages won’t be sent at all. This option is ignored when PGP is disabled.

info [jid]
Show current PGP settings for the contact

setkey [jid [key]]
Set the PGP key to be used to encrypt message for this contact. If no key is
provided, the current key is erased. You can use the shortcut-jid "." for the
currently selected contact.

/quit
This command closes all connections and quit mcabber.

/rawxml send string
Send "string" (raw XML format) to the Jabber server.

No check is done on the string provided.

BEWARE! Use this only if you know what you are doing, or you could terminate the
connection.

Example: "/rawxml send <presence><show>away</show></presence>"

/rename name

resource is not provided with the jid, mcabber will send the query to all known
resources for this user.

displayed. If text is "-", the note is erased.

/say [-n|-h|--] text
Send the "text" message to the currently selected buddy. It can be useful if you want
to send a message beginning with a slash, for example.

The "-n" flag turns the message to "normal" type, "-h" to "headline". "--" can be used
to send chat message beginning with -n or -h.

/say_to [-n|-h] [-q] [-f file] jid text
Send the "text" message to the specified jid.

Please note that this command doesn’t set the default resource for a contact, so if
you want to send several messages to a specific resource you will have to use
"/say_to" for each message.

You can send a message to a specific resource of the currently selected contact by
using /say_to ./resourcename message.

The "-n" flag turns the message to "normal" type, "-h" to "headline". "--" can be used
to send chat messages beginning with -n or -h.

When "-q" is used, the message will be sent in the background and will not change the
current active window.

A text file can be provided with the "-f" switch (in which case there’s no need to
pass a text argument after the jid, of course).

/screen_refresh
Refresh the mcabber screen.

/set [option [= value]]
Display or set an option value.

Without arguments prints a list of all set options with their values

/source pattern

If a status message is specified, it will overrride the message* variables (these
variables can be set in the configuration file).

If no relevant message* variable is set and no status message provided, the current
status message is kept.

If StatusMessage is "-", the current status message is cleared.

With the "/status message" command, mcabber will update the message while preserving
the status.

/status_to jid online|avail|free|dnd|notavail|away [statusmessage], /status_to jid message
statusmessage
Send the requested status to the specified Jabber user.

If the specified jid is ".", the current buddy is used.

Note: this status will be overridden by subsequent "/status" commands. If you are
using the auto-away feature, the status will overridden too.

Note: The jid can include a resource (i.e. user@server/resource).

/version
Display current version of mcabber.
