=head1 DESCRIPTION |
45
|
|
|
|
|
|
|
|
46
|
|
|
|
|
|
|
This module lets you interact with the |
47
|
|
|
|
|
|
|
(L) API. See |
48
|
|
|
|
|
|
|
L, L, and L for details about |
49
|
|
|
|
|
|
|
what data you can get from the API. |

=head1 METHODS |
52
|
|
|
|
|
|
|
|
53
|
|
|
|
|
|
|
Right now, everything is a class method since the weewar API is public |
54
|
|
|
|
|
|
|
for everything except the HQ (and no state needs to be kept between |
55
|
|
|
|
|
|
|
requests). If this changes, then this API will change a bit. |

92
|
|

|
|
|
|
|
|
|
Return a list of all active Weewar users as L objects. |
94
|
|
|
|
|
|
|
The objects are loaded lazily, so this method only causes one request |
95
|
|
|
|
|
|
|
to be sent to the server. When you start accessing the returned |
96
|
|
|
|
|
|
|
children, they will be populated on-demand from the server. |
97
|
|
|
|
|
|
|
|
98
|
|
|
|
|
|
|
An exception will be thrown if something goes wrong. |

You can use different weewar servers by changing these environment |
165
|
|
|
|
|
|
|
variables. I doubt there are other weewar servers that speak this |
166

|
|
|
|
|
|
API, though. |

|
|
|
182
|
|
|
|
|
|
|
If the Weewar API changes, this module will need an update. Let me |
183
|
|
|
|
|
|
|
know if something is broken so I can fix it. |
184
|
|
|
|
|
|
|
|
185
|
|
|
|
|
|
|
The combination of Weewar's odd XML, C, and the fact that |
186
|
|
|
|
|
|
|
I had very little sleep before writing this makes for some very ugly |
187
|
|
|
|
|
|
|
code. Feel free to clean it up and send me a patch. |
188
|
|
|
|
|
|
|
|
189
|
|
|
|
|
|
|
Bugs should be reported through RT, but you can email me directly too. |
