@node Configuration, Using the Bot, Introduction, Top
@chapter Configuration

Bobot++ is easy to configure. See the @file{examples} directory for an
example configuration. 

The main configuration file is @file{bot.conf}. There are several
auxiliary configuration files (a user list, aliases file, ban list,
and a script autoexec).

@section Configuration File Placement

Bobot++ will look in @file{/etc/bobotpp/default/} for its default
config if none is specified on the command line. Put the configuration
files you want to be loaded by default in this directory. If you are
not root, or you want to have your own personal configuration, put it
in @file{~/.bobotpp/config/default/}.

@subsection bot.conf

@file{bot.conf} contains key value pairs separated by @code{=}. 

@code{<key> = <value>}

Comments are started with a @code{#} and cause the entire line to be

character of the line}.

bot.conf is the main configuration file for a Bobot++. The available
configuration variables are listed below in the format ``@var{variable}

A few of the options have more complex syntax, they are documented in
their own subsections.

@node server syntax, channel syntax, bot.conf, bot.conf
@subsubsection server syntax

The server syntax in @file{bot.conf} allows you to specify an
alternate port to connect on, and a password to send the server.

You may use more than one server line; Bobot++ will attempt to connect
to the first one, and will connect to the next one in the list if it
fails. The bot will continue cycling through the server list until it
is able to connect to one. There is a command (@code{!cycle}) to make
the bot to cycle servers.

@var{server} = @var{server_name} [@var{port} [@var{password}]]

This will make Bobot++ attempt to connect to @var{server_name} on port
@var{port} with the password @var{password}. @var{server_name} should
be the address of the server. @var{port} and @var{password} are
optional. 

@node  channel syntax,  , server syntax, bot.conf
@subsubsection channel syntax

The channel syntax in @file{bot.conf} allows you to specify the
initial modes the bot should set on a channel, the modes the bot
should maintain, and a key if the channel needs it.

You may have any number of channel lines. When Bobot++ starts it will
attempt to join and gain operator status in every channel listed.

@var{channel} =
@var{name}:@var{initial_modes}:@var{modes_to_keep}:@var{channel_key}

The bot will join @var{name} and set the channel modes to
@var{initial_modes} (e.g. ``nt'') if it is able to gain operator
status. It will then maintain @var{modes_to_keep}. If the channel
requires a key to enter simply set @var{channel_key}. Every argument
except for @var{name} is optional.

A few example lines:

@example
@var{channel} = #foo:nt:nt:bar
@end example

The bot will join @code{#foo} with the channel key @code{bar} and will
then maintain the modes @code{nt}.

@example
@var{channel} = #bar:::
@end example

The bot will join @code{#bar} and will not set any modes nor will it
attempt to maintain any modes.

@node bot.users,  , bot.conf, Configuration Files
@subsection bot.users

@file{bot.users} is the default file name of the userlist. It may be
changed in @file{bot.conf}. The file contains lines with the format:

@samp{@var{mask}:@var{channel}:@var{level}:@var{protection}:@var{auto-op}}

@itemize

@item @var{mask} is the host mask
(e.g. @samp{*!*username@*.domain.com}) of the user

@item @var{channel} is a channel mask of the channels that the user
has priviliges to use the bot in (e.g. @samp{*} for all channels,
@samp{#*} for all non-local channel, @samp{#foo*} for all channels
starting with ``foo,'' @samp{#bar} for channel ``#bar'' only, etc.)

@item @var{level} is the user level of the user (@ref{User Levels}).

@item @var{protection} is the protection level of the user
(@ref{Protection}).

@item @var{auto-op} is set to control whether a user is automatically
given operator priviliges on channel entry (@ref{Automatic Op}).

@node Starting the Bot, User Levels, Using the Bot, Using the Bot
@section Starting the Bot

The bot is usually installed with the binary name @file{bobotpp}. It
accepts the following command line arguments.

@itemize
@item @code{[--help][-h]} - Shows detailed help and exits
@item @code{[--version][-v]} - Shows version information and exits
@item @code{[--no-background][-b]} - Run bobot++ in the foreground
@item @code{[--config-file file][-f]} - Use file instead of @file{bot.conf}
@item @code{[--config-dir dir][-d]} - Use dir as dir to load config file from
@item @code{[--config dir][-c]} - Search your config path (defaults to
@file{@var{$HOME}/.bobotpp/config/} and then @file{/etc/bobotpp/}) for
dir and then loads your config data using dir
@item @code{[--sys-config dir][-s]} - Looks for config in
@file{/etc/bobotpp/dir}. Note that the user dir is still searched
first
@item @code{[--user-config dir][-u]} - Looks for config in
@file{@var{$HOME}/.bobotpp/config/dir/}. Note that the system dir is
still searched after this if dir is not found.
@item @code{[--debug][-D]} Makes Bobot++ print debugging info and run
in the foreground
@item @code{[--debug-scripts][-S]} Enabled the Guile debugging
evaluator for verbose script errors and backtraces while still running
the bot in the background.
@end itemize

The default configuration is read from
@file{@var{$HOME}/.bobotpp/config/default/} and then
@file{/etc/bobotpp/default/} if the user config is not found.

The bot defaults to running in the background as a daemon.

@node User Levels, Protection, Starting the Bot, Using the Bot
@section User Levels

There are several user levels available in Bobot++ to provide gradated
access to commands. @command{!adduser} and @file{bot.users} use the
numeric code; Scheme uses the textual name for the level. By default
(if the user is not found in the userlist) a user has access to
commands with the level @code{bot:user-none}.

@enumerate 0

@item @code{bot:user-none} - No @strong{built-in} commands may be
executed @emph{by default} (commands may be added from Scheme that can
be executed by users of level none and the level required to execute a
command may be changed from Scheme).

@item @code{bot:user-user} - Will be able to execute most commands but
not all and cannot use masks on kicks and bans.

@item @code{bot:user-trusted} - For built-ins with a default
configuration this user has access to the same set of commands as an
@code{user} but may use masks on kicks and bans. Scheme commands may
be added which require a user to be of this level.

@item @code{bot:user-friend} - In the default configuration a user who
is a friend will be able to do everything short of stopping the
bot. Again, there may be user added commands that require a higher
user level.

@item @code{bot:user-master} - This is the highest user level and has
access to every feature of the bot.

@end enumerate

@node Protection, Automatic Op, User Levels, Using the Bot
@section Protection

A user added via Scheme, the @file{bot.users} file, or
@command{!adduser} may be protected from being deoped, kicked, or
banned. The user list and IRC commands use the numeric codes, Scheme
uses the symbolic names.

@enumerate 0
@item @code{bot:protection/none} No protection
@item @code{bot:protection/no-ban} No ban. If a user is banned the bot will unban him..
@item @code{bot:protection/no-kick} No kick. The user may still be kicked but the bot will kickban
the user who kicked the protected user.
@item @code{bot:protection/no-deop} No deop. The bot will ensure that the user always maintains
operator status.
@end enumerate

@node Automatic Op, Built-In Commands, Protection, Using the Bot
@section Automatic Op

A user may be automatically given operator status upon entering a
channel. Scheme uses the symbolic name, the user list
(@file{bot.users}) and IRC commands use the numeric value.

@enumerate 0
@item @code{bot:aop/no} Do not automatically op the user
@item @code{bot:aop/yes} Do automatically op the user
@end enumerate

@node Built-In Commands,  , Automatic Op, Using the Bot
@section Built-In Commands

Bobot++ has many built-in commands that make it useful without
scripting support. The reference leaves off the command char; remember
to use whatever you defined the command char to be in
@file{bot.conf}. If a command needs the channel name then you must
specify the channel as the first argument to the command when private
messaging the bot a command.

@node Scripting, Concept Index, Using the Bot, Top
@chapter Scripting

Bobot++'s most powerful feature is its scripting system. You write
scripts using Guile Scheme. This manual does not cover how to use
Guile or how to learn Scheme. @xref{Top, , Guile Reference Manual,
guile, The Guile Reference Manual}, for the Guile reference manual and
@url{http://www.ccs.neu.edu/home/dorai/t-y-scheme/t-y-scheme.html} for
a good tutorial on Scheme. 

Note that in previous versions the scripting commands where in the
form @code{bot-@var{function}}. They are now in the form
@code{bot:@var{function}}. The old names are still available, but are
deprecated and will be removed in Bobot++ 3.0. New commands are only
available with the @code{bot:} prefix. The command @command{perl -pi
-e ``s/bot-/bot:/g'' @var{your-files}} should be enough to convert
your code to use the new functions.

@strong{NOTE}: All arguments to functions and hooks called by the bot
are strings unless otherwise specified.

@node Adding New Commands, Hooks, Scripting, Scripting
@section Adding New Commands

Adding a new command is simple. To register a new command use
@code{bot:addcommand}.

@defun bot:addcommand name func needs-channel? num-of-args min-level

The @var{name} is a string representing the name of the command being
added.  @var{func} is a function accepting @var{num-of-args}
arguments. @var{needs-channel?} is a bool that is true if the function
needs the channel name as its first arg, and false otherwise.
@var{num-of-args} is the number of args @var{func} will take and must
be within zero (0) and twenty (20).  @var{min-level} is one of the
@ref{Scheme User Levels}.  A user must be at least a @code{min-level}
user to use the new command.  None of the arguments are guaranteed to
be passed; if they aren't they are set to the empty string @code{""}.
An example of a new command would be:

@example
(define (hello channel name)
  (if (string=? name "")
    (bot:say channel "Hello world!")
    (bot:say channel (string-append "Hello " name "!")))

(bot:addcommand "hello" hello #t 2 0)
@end example

This will display ``Hello World!'' if called as @kbd{!hello} and
``Hello World @var{USER}'' if called as @kbd{!hello @var{USER}}.

@node Hooks, Scheme User Levels, Adding New Commands, Scripting
@section Hooks

@cindex Background on Hooks
Hooks are a powerful feature of Bobot++. Hooks are a hybrid of ircII
and tiny fugue (a MUD bot) hooks with a little bit of extra stuff
added in. A hook is called when a regular expression is matched
against a message sent to or by the bot.

Bobot++ uses different hook types for each IRC message type, and also
includes a hook for accessing raw irc messages. Hooks are tagged with
a priority and a flag that specifies whether to call the next hook
that matches after calling the current one or to stop
processing. 

Hooks are processed from the highest to lowest priority, with
fallthrough hooks of equal priority to non-fallthrough hooks being
executed first.

* Creating a Hook::             
* Hook Types::                  
@end menu

@node Creating a Hook, Hook Types, Hooks, Hooks
@subsection Creating a Hook

To add a new hook you use the function @code{bot:addhook}.

@defun bot:addhook type regex function [pri fall name]
@var{type} specifies the type of hook (the types of hooks are listed
in @ref{Hook Types}). 

@var{regex} is a standard regular expression. If
@var{regex} is matched, @var{function} will be called. 

@var{function} will take a different number of args depending on the
hook type. 

@var{pri} specifies the priority of the hook---higher priority hooks
are executed first. This argument is optional and defaults to
@code{0}. 

@var{fall} is @code{#t} if the hook is a fallthrough hook and
@code{#f} is the hook is not a fallthrough hook. This arg is also
optional and defaults to @code{#t}.

@var{name} is the optional name of the hook that defaults to
@code{"DEFAULT"}. If you set the name then you can have more than
one hook that matches the same regexp, as long as they have the same
name. E.g. in a log script you could have the regexps for the log
function all be @code{".*"} and set their names to @code{"log"} to
avoid a conflict with other hooks.
@end defun

@node Hook Types,  , Creating a Hook, Hooks
@subsection Hook Types

The following sections document the different hooks Bobot++ exposes.

The general format of each hook description is as if it were a
function to be defined, but these describe the function to be passwd
to @code{bot:add-hook}.  Do @emph{not} name your functions these
names.

That said, here is the list of available hooks functions.

@subsubsection Receieved Message Hooks

The following hooks are triggered when a mesage is received by the bot.

@defun hooks/action from to action
This hook is triggered when someone performs an action.

@var{from} is the nickname the person that performed the
action.

@var{to} is the target of the action, which is either a channel or the
Bot's nick if the user private messages the bot.

@var{action} is the text of the action. E.g. if someone did @samp{*
foobar does baz}, then @var{action} would be the string @code{"does
baz"}.
@end defun

@defun hooks/nickname old-nick new-nick
This hook is called when someone changes his nickname from
@var{old-nick} to @var{new-nick}.
@end defun

@defun hooks/signoff nick message
This hook is called when someone signs off of IRC.

@var{nick} is the nickname of the person signing off.

@var{message} is his quit message
@end defun

@defun hooks/ctcp nick to command rest
This hook is called when a CTCP request is received by the bot.

@node Scheme User Levels, Sending Messages, Hooks, Scripting
@section Scheme User Levels

@vindex user-none
@vindex user-user
@vindex user-trusted
@vindex user-friend
@vindex user-master
There are five levels that a user may be when interfacing with a bot:
@var{none}, @var{user}, @var{trusted_user}, @var{friend},
@var{master}. The Scheme variables for the user levels are
@code{bot:user-none}, @code{bot:user-user}, @code{bot:user-trusted},
@code{bot:user-friend}, and @code{bot:user-master}. See @ref{User
Levels} for more information on User Levels. 

When adding a new command, think about who should be able to use
it. Is your command a general purpose command that helps the channel
(e.g. @code{!seen}) that everyone should be able to use? Or is it
something that should be restricted? See @ref{User Levels} for
information on what level users can do what with the built in bot
commands and think about what level a user your command is targetted
towards. You must be @emph{very} careful when giving new commands to
lower level users because you can do basically everything the bot can
do with a script. As the scripting interface becomes more powerful,
you must think more about what users can use new commands you add.

@node Sending Messages, Misc Scripting Stuff, Scheme User Levels, Scripting
@section Sending Messages

There are several types of messages you can send with Bobot++ from
scripts. There is the simple, but rather limited, @code{bot:say},
@code{bot:action} and @code{bot:msg}, and the more powerful, but lower
level, @code{bot:send-MESSAGE} functions. Most bots will probably only
need the higher level functions, but for the sake of why-not Bobot++
lets you use the lower level functions (in progress).

@defun bot:say channel message
Send a public or private @var{message} to @var{channel}.

@var{dest} can be a nickname or a channel.
@end defun

@defun bot:action channel message
Send an ``action'' type  @var{message} to @var{channel}
@end defun

@defun bot:msg nick message
The same as if a user typed @code{/msg nick message} to their IRC client.
@end defun

Sends @var{message} as a NOTICE to @var{target}. @var{target} may be a
user (nick) or a channel. This returns 0 on success.
@end defun

@node Low Level Message Functions,  , High Level Message Functions, Sending Messages
@subsection ``Low Level'' Message Functions

@c Add a url for rfc2812
The ``Low Level'' messaging functions allow you to do things like send
CTCP messages. You probably want to read rfc 2812 and the CTCP spec
before using these. If you have no idea what these do, read rfc 2812
(IRC Client Protocol) and CTCP spec. These functions all return
@code{*unspecified*} always, so don't use the return value for
anything.

@defun bot:send-ctcp to command message
@var{to} is the target of your CTCP message, @var{command} is the
CTCP command, and @var{message} is the message (or arguments) of the
command. Make sure to @code{bot:ctcp-quote} the message!
@end defun

@defun bot:send-ctcp-reply to command message
@var{to} is the target of your CTCP reply, @var{command} is the
CTCP command, and @var{message} is the message (or arguments) of the
command. Make sure to @code{bot:ctcp-quote} the message!

This is used to reply to a ctcp that the bot has received.
@end defun

@node Misc Scripting Stuff,  , Sending Messages, Scripting
@section Misc. Scripting Stuff

These are a few useful things that I thought people writing scripts
might want to know.

@vindex exit-hook
If you want to execute code when the bot exits, just do
@code{add-hook! bot:exit-hook @var{thunk}} where @var{thunk} is an
argumentless procedure (a thunk). When the bot exits your thunk will
be called.

@quotation
[ I didn't know where to put any of these, so I just stuck them in
here.

There probably needs to be several sections added, like dealing with
users (kicking, added, etc), dealing with the bot (channels, nickname
of the bot, etc), server issues (serverlist), useful tools (nslookup,
whois), and do on. ]
