@chapter Configuration

Bobot++ is easy to configure. The configuration file format may be
changing in the 2.1 series, so it is not documented for now. See the
@file{examples} directory for an example configuration.

@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 configration, put it in
@file{~/.bobotpp/config/default/}.

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

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}. All users default to @var{none} unless they are changed
by a script, the @code{!adduser} command or the @file{bot.users}
file. @var{none} is for everyone---very few commands (e.g. help) are
available to the users and almost everyone should be this
level. A @var{user} can execute many of the bot commands, but can't
use masks on kicks and bans. A @var{trusted} user can everything a
@var{user} can do, but can also use masks on kicks and bans. A
@var{friend} can do everything except for stopping the bot (be
careful who you give this to!). The @var{master} level is for the
bot's owner (probably you) and can do @emph{everything} to the bot. Be
@emph{very} careful if you give @var{master} level access to anyone
else. You cannot use this symbolic levels with the @code{!adduser}
command. See (FIXME: ref) for the numbers you must use with
@code{!adduser}.

@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++ 2.4. 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.

@section Adding New Commands

@findex addcommand
Adding a new command is simple. To register a new command use
@code{bot:addcommand}. The prototype for @code{bot:addcommand} is
@code{(bot:addcommand name func needs-channel? num-of-args
min-level)}. The @code{name} is a string representing the name of the
command being added. @code{func} is a function accepting
@code{num-of-args} arguments. @code{needs-channel?} is a bool that is
true if the function needs the channel name as its first arg, and
false otherwise. @code{num-of-args} is the number of args @code{func}
will take and must be within zero (0) and twenty
(20). @code{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:
@verb{|
(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)
|}
This will display ``Hello World!'' if called as @kbd{!hello} and
``Hello World @code{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
hooks and tiny fugue (a MUD bot) hooks. The basic idea of a hook if
that you match a text against regular expression and call a function
if text in a message matches that regex. The different types of hooks
provided by Bobot++ correspond to the different classes of messages
that Bobot++ can recieve. A Hook also has several properties,
including its priority and whether or not it is a fallthrough
hook. Higher priority hooks are executed before lower priority hooks
and fallthrough hooks are executed before non-fallthrough hooks. A
fallthrough hook can match and processing of hooks will continue; as
soon as the first non-fallthrough hooks matches processing of hooks
stops.

@subsection Creating a Hook

@findex addhook
To add a new hook you use the function
@code{bot:addhook}. @code{bot:addhook} is prototyped as
@code{(bot:addhook type regex function pri fall)}. @code{type}
specifies the type of hook (the types of hooks are listed in @ref{Hook
Types}). @code{regex} is a standard regular expression. If
@code{regex} is matched, @code{function} will be
called. @code{function} will take a different number of args depending
on the hook type. @code{pri} specifies the priority of the
hook---higher priority hooks are executed first. This argument is
optional and defaults to @code{0}. @code{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 default to @code{#t}.

@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,  , 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.

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

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.

@itemize @bullet

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