CATGIRL(1) FreeBSD General Commands Manual CATGIRL(1)

catgirl —
IRC client

catgirl [-KRelqv] [-C copy] [-H hash] [-I highlight] [-N notify] [-O open] [-S bind] [-T[timestamp]] [-a plain] [-c cert] [-h host] [-i ignore] [-j join] [-k priv] [-m mode] [-n nick] [-p port] [-r real] [-s save] [-t trust] [-u user] [-w pass] [config ...]

catgirl -o [-S bind] [-h host] [-p port] [config ...]

catgirl -g cert

The catgirl IRC client provides a curses interface for TLS-only Internet Relay Chat. The only required option is -h, the host name to connect to. See EXAMPLES for managing further configuration. Type /help in catgirl to view the list of COMMANDS and KEY BINDINGS.

Options can be loaded from files listed on the command line. Files are searched for in $XDG_CONFIG_DIRS/catgirl (usually ~/.config/catgirl) unless the path starts with ‘/’, ‘./’ or ‘../’. Files and flags listed later on the command line take precedence over those listed earlier.

Each option is placed on a line, and lines beginning with ‘#’ are ignored. The options are listed below following their corresponding flags.

util | = util
Set the utility used by /copy. Subsequent copy options append arguments to util. The URL to copy is provided to util on standard input. The default is the first available of pbcopy(1), wl-copy(1), xclip(1), xsel(1).
seed,bound | = seed,bound
Set the initial seed of the nick and channel color hash function and the maximum IRC color value produced by the function. The default is 0,75. To use only colors from the 16-color terminal set, use 0,15. To disable nick and channel colors, use 0,0.
pattern | = pattern
Add a case-insensitive message highlight pattern, which may contain ‘*’, ‘?’ and ‘[]’ wildcards as in glob(7). The format of the pattern is as follows:
nick[!user@host [command [channel [message]]]]

The commands which can be matched are: INVITE, JOIN, NICK, NOTICE, PART, PRIVMSG, QUIT, SETNAME.

|
Disable the /copy, /debug, /exec, /join, /list, /msg, /open, /part, /query, /quote commands. Replace the username with a hash of its original value.
util | = util
Send notifications using a utility. Subsequent notify options append arguments to util. The window name and message are provided to util as two additional arguments, appropriate for notify-send(1).
util | = util
Set the utility used by /open. Subsequent open options append arguments to util. The URL to open is provided to util as an argument. The default is the first available of open(1), xdg-open(1).
|
Disable the /copy, /exec and /open commands, the notify option, and viewing this manual with /help.
host | = host
Bind to source address host when connecting to the server.
[format] | [= format]
Show timestamps by default, in the specified strftime(3) format. The format string may contain raw IRC formatting codes. The default format is “%X”.
user:pass | = user:pass
Authenticate as user with pass using SASL PLAIN. Leave pass blank to prompt for the password.
path | = path
Load the TLS client certificate from path. The path is searched for in the same manner as configuration files. If the private key is in a separate file, it is loaded with priv. With sasl-external, authenticate using SASL EXTERNAL. Certificates can be generated with -g.
|
Authenticate using SASL EXTERNAL, also known as CertFP. The TLS client certificate is loaded with cert. See Configuring CertFP.
path
Generate a TLS client certificate using openssl(1) and write it to path.
host | = host
Connect to host.
pattern | = pattern
Add a case-insensitive message ignore pattern, which may contain ‘*’, ‘?’ and ‘[]’ wildcards as in glob(7). The format of the pattern is as follows:
nick[!user@host [command [channel [message]]]]

The commands which can be matched are: INVITE, JOIN, NICK, NOTICE, PART, PRIVMSG, QUIT, SETNAME.

channels [keys] | = channels [keys]
Join the comma-separated list of channels with the optional comma-separated list of channel keys.
path | = priv
Load the TLS client private key from path. The path is searched for in the same manner as configuration files.
|
Log chat events to files in paths $XDG_DATA_HOME/catgirl/log/network/channel/YYYY-MM-DD.log.
mode | = mode
Set the user mode.
nick | = nick
Set nickname to nick. The default nickname is the value of the environment variable USER.
Print the server certificate chain to standard output in PEM format and exit.
port | = port
Connect to port. The default port is 6697.
|
Raise the default message visibility threshold for new windows, hiding general events (joins, quits, etc.).
real | = real
Set realname to real. The default realname is the same as the nickname.
name | = name
Save and load the contents of windows from name in $XDG_DATA_DIRS/catgirl, or an absolute or relative path if name starts with ‘/’, ‘./’, or ‘../’.
path | = path
Trust the self-signed certificate loaded from path and disable server name verification. The path is searched for in the same manner as configuration files. See Connecting to Servers with Self-signed Certificates.
user | = user
Set username to user. The default username is the same as the nickname.
|
Log raw IRC messages to the <debug> window as well as standard error if it is not a terminal.
pass | = pass
Log in with the server password pass. Leave pass blank to prompt for the password.

  1. Generate a new TLS client certificate: 
    $ catgirl -g ~/.config/catgirl/example.pem
  2. Connect to the server using the certificate: 
    cert = example.pem
# or: $ catgirl -c example.pem
  3. Identify with services or use sasl-plain, then add the certificate fingerprint to your account: 
    /ns CERT ADD
  4. Enable SASL EXTERNAL to require successful authentication when connecting (not possible on all networks): 
    cert = example.pem
sasl-external
# or: $ catgirl -e -c example.pem

  1. Connect to the server and write its certificate to a file: 
    $ catgirl -o -h irc.example.org > ~/.config/catgirl/example.pem
  2. Configure catgirl to trust the certificate: 
    trust = example.pem
# or: $ catgirl -t example.pem

The catgirl interface is split into three areas.

The top line of the terminal shows window statuses. Only the currently active window and windows with activity are listed. The status line for a window might look like this: 
1+ #ascii.town +3 ~7 @

The number on the left is the window number. Following it may be one of ‘-’, ‘+’, ‘++’, as well as ‘=’. These indicate the message visibility threshold and mute status of the window.

On the right side, the number following ‘+’ indicates the number of unread messages. The number following ‘~’ indicates how many lines are below the scroll position. An ‘@’ indicates that there is unsent input in the window's Input Line.

catgirl will also set the terminal title, if possible, to the name of the network and active window, followed by the unread count for that window, and the unread count for all other windows in parentheses.

The chat area shows messages and events. Regular messages are shown with the nick between ‘<>’ angle brackets. Actions are shown with the nick preceded by ‘*’. Notices are shown with the nick between ‘-’ hyphens.

Blank lines are inserted into the chat as unread markers.

While scrolling, the most recent 5 lines of chat are kept visible below a marker line.

The bottom line of the terminal is where messages and commands are entered. When entering a message, action or notice, your nick appears on the left, as it would in the Chat Area. When entering a command, no nick is shown.

Formatting codes are shown in the input line as reverse-video uppercase letters. These will not appear in the sent message.

Input that is too long to send as a single message will have a red background starting at the point where it will be split into a second message.

Any unique prefix can be used to abbreviate a command. For example, /join can be typed /j.

The most likely location of configuration files.
$XDG_DATA_DIRS/catgirl

Join #ascii.town from the command line: 
$ catgirl -h irc.tilde.chat -j '#ascii.town'

Create a configuration file in ~/.config/catgirl/tilde:

host = irc.tilde.chat
