---|
21 | =head1 DESCRIPTION |
---|
22 | |
---|
23 | The BarnOwl module contains the core of BarnOwl's perl |
---|
24 | bindings. Source in this module is also run at startup to bootstrap |
---|
25 | barnowl by defining things like the default style. |
---|
26 | |
---|
27 | =for NOTE |
---|
28 | These following functions are defined in perlglue.xs. Keep the |

---|
80 | |

87 | Displays C<PROMPT> on the screen and lets the user enter a line of |

---|
108 | |
---|
109 | Returns the BarnOwl user configuration directory, where user modules |
---|

---|
111 | |
---|
112 | =head2 popless_text TEXT |
---|
113 | |
---|
114 | Show a popup window containing the given C<TEXT> |
---|
115 | |
---|
116 | =head2 popless_ztext TEXT |

117 | |
---|
118 | Show a popup window containing the provided zephyr-formatted C<TEXT> |
---|
119 | |
---|
120 | =head2 error STRING |
---|
121 | |
---|
122 | Reports an error and log it in `show errors'. Note that in any |
---|
123 | callback or hook called in perl code from BarnOwl, a C<die> will be |
---|
124 | caught and passed to C<error>. |
---|
125 | |
---|
126 | =head2 getnumcolors |
---|
127 | |
---|
128 | Returns the number of colors this BarnOwl is capable of displaying |

---|
141 | |
---|
142 | Creates a new barnowl style with the given NAME defined by the given |
---|
143 | object. The object must have a C<description> method which returns a |
---|
144 | string description of the style, and a and C<format_message> method |
---|
145 | which accepts a C<BarnOwl::Message> object and returns a string that |
---|
146 | is the result of formatting the message for display. |

176 | =head2 AUTOLOAD |
---|
177 | |
---|
178 | BarnOwl.pm has a C<AUTOLOAD> method that translates unused names in |
---|
179 | the BarnOwl:: namespace to a call to BarnOwl::command() with that |
---|
180 | command. Underscores are also translated to C<->s, so you can do |
---|
181 | e.g. C<BarnOwl::start_command()> and it will be translated into |
---|
182 | C<start-command>. |
---|
183 | |
---|
184 | So, if you're looking for functionality that you can't find in the |
---|
185 | perl interface, check C<:show commands> or C<commands.c> in the |
---|
186 | BarnOwl source tree -- there's a good chance it exists as a BarnOwl |
---|
187 | command. |
---|
188 | |
---|
189 | =head3 BUGS |
---|
190 | |
---|
191 | There are horrible quoting issues here. The AUTOLOAD simple joins your |
---|
192 | commands with spaces and passes them unmodified to C<::command> |

208 | be called with the arguments passed to the command, with NAME as the |
---|
209 | first argument. |

---|
787 | =head1 DESCRIPTION |
---|
788 | |
---|
789 | C<BarnOwl::Hooks> exports a set of C<BarnOwl::Hook> objects made |
---|
790 | available by BarnOwl internally. |
---|
791 | |
---|
792 | =head2 USAGE |
---|
793 | |
---|
794 | Modules wishing to respond to events in BarnOwl should register |
---|
795 | functions with these hooks. |
---|
796 | |
---|
797 | =head2 EXPORTS |
---|
798 | |
---|
799 | None by default. Either import the hooks you need explicitly, or refer |
---|
800 | to them with fully-qualified names. Available hooks are: |
---|
801 | |
---|
802 | =over 4 |
---|
803 | |
---|
804 | =item $startup |
---|
805 | |
---|
806 | Called on BarnOwl startup, and whenever modules are |
---|
807 | reloaded. Functions registered with the C<$startup> hook get a true |
---|
808 | argument if this is a reload, and false if this is a true startup |
---|
809 | |
---|
810 | =item $shutdown |
---|
811 | |
---|
812 | Called before BarnOwl shutdown |
---|
813 | |
---|
814 | =item $receiveMessage |
---|
815 | |
---|
816 | Called with a C<BarnOwl::Message> object every time BarnOwl receives a |
---|
817 | new incoming message. |
---|
818 | |
---|
819 | =item $newMessage |
---|
820 | |
---|
821 | Called with a C<BarnOwl::Message> object every time BarnOwl appends |
---|
822 | I<any> new message to the message list. |
---|
823 | |
---|
824 | =item $mainLoop |
---|
825 | |
---|
826 | Called on every pass through the C<BarnOwl> main loop. This is |
---|
827 | guaranteed to be called at least once/sec and may be called more |
---|
828 | frequently. |
---|
829 | |
---|
830 | =item $getBuddyList |
---|
831 | |
---|
832 | Called to display buddy lists for all protocol handlers. The result |
---|
833 | from every function registered with this hook will be appended and |
---|
834 | displayed in a popup window, with zephyr formatting parsed. |
---|
835 | |
---|
836 | =item $getQuickstart |
---|
837 | |
---|
838 | Called by :show quickstart to display 2-5 lines of help on how to |
---|
839 | start using the protocol. The result from every function registered |
---|
840 | with this hook will be appended and displayed in an admin message, |
---|
841 | with zephyr formatting parsed. The format should be |
---|
842 | "@b(Protocol:)\nSome text.\nMore text.\n" |
